I’m not asking for coffee money, BUT I do need some more DropBox space – if you sign up to DropBox by clicking this link, then YOU will get an additional 250MB of free storage, and I will also get the same. And I need it!
If you don’t know about dropbox, it is time you learned – it is how I keep all of my precious photos now – by saving them in my DropBox folder, two things happen:
1. A copy is saved offsite at DropBox,
2. The saved copy is synched with another computer at home – AUTOMATICALLY
Hi,
Despite my english is poor (I’am french man), big congratulations for you job. I begin with GNS3 in order to play with ASA and I have an error with “qemu”. When I have perform “Test setting” in qemu tab (preference), I have the error “failed to start qemu”. Where are located “qemu” and “qemu-img”?
Thanks, Constant
Hi Constant,
When I created GNS3 workbench, I aimed it at CCNA level exercises, so I did not include and Qemu options. Sorry. I’ll try and get back to you with the steps you would need to take, but it might take a few days. Very bust testing GNS3 0.8.4 RC2 right now.
CW
SIr, If possible, kindly develop the GNS3 workbench from torrent mode.
Thank you.
I have tried before, but it didn’t seem to get taken up. This is why I have tried to make the files smaller and have them on http://sourceforge.net/projects/gns3workbench/files/v5.8/
If anyone else has downloaded the package and wants to put it on a torrent, please do.
CW
I tried to put the files on torrent once, but it seemed that there wasn’t enough demand to make it work. This is why I split the last version into smaller files that can be downloaded from http://sourceforge.net/projects/gns3workbench/files/v5.8/
If anyone has a copy and wants to put it on a torrent, please do.
CW
Does it work with VirtualBox?
I believe GNS3 WorkBench works fine with Virtual Box – from memory, I think you have to convert the files to .ova format first.
CW
Red,
I was curious to know if you or someone is actively working on another updated release of your fantastic GNS3 Workbench not that 0.8.3.1 is out and 0.8.4 is on the way? Thanks.
Waiting for 0.8.4 to be officially released.
Fantastic!! Love the Workbench. Keep it up:-)
Firstly Wow! thanks for all this….., gotta love Aussie ingenuity!!!
Just wondered if for some exercises/labs that contain 2 or more routers, should all the routers be accessible? e.g. “/ICND2 Exercises/ACL Exercise”. Here I don’t have access to the “Edge” router, (login/password??) & for the purpose of the exercise probably don’t need it. Is this by design?
Again thanks
Chris
Probably the errors are to do with the dodgy way I did some of the scripting for parts that needed to be run as “sudo” – what I’ve done for the next version (and should have done in the beginning) is edit the sudoers file and add the line “%admin ALL=NOPASSWD: ALL”
HTH
Chris
Unfortunately I tried that and it didn’t work. From what I read they no longer use the admin group, its sudo now. so I used sudo instead but also tried creating admin group and no luck.
Right now I have a freshly created vm of Ubuntu 12.04LTS x64
with everything properly installed and working
But the scripts only work if I right click and open folder as root
then start the scripts…or log into root.
Example:
right click on Standard layouts on desktop
open as administrator (had to add a nautilus extension to do that)
input password
then click on “1 Router (reset lab)” and GNS3 and the konsole window with vpcs and instructions work.
*Had to reinstall vpcs
Thanks again for all the hard work… now I can work on getting my CCNA
Bill
OH I cant get the vlans to work yet… I input the info from /etc/network/interfaces and Ubuntu takes forever to boot and eventually gives a message about not using full network. Cant figure that out yet.
First I see:
Waiting for network configuration…
Then I see:
Waiting up to 60 more seconds for network configuration…
And then it displays the following:
Booting system without full network configuration…
Then eventually boots

I started using this and thank you very much but was wondering if there was a way to convert/move this stuff to a windows pc? I already have gns3 configured and working but have had trouble trying to copy the various tutorials/exercises, etc
Again thank you for all the hard work
Bill
It would certainly be possible to copy the .net files and .cfg directories to windows, but you may have to edit the .net files to point to the correct directories. But a lot of the “ease” of the workbench is having vpcs start automatically, and have some instructions displayed automatically. To do that in windows would mean translating all the Linux script files to Windows .bat or .cmd files. And that may well be impossible. But if you want to try….. Good luck!
Chris (RedNectar)
Thanks for answering, I will try that later, I like how you set it all up.
One question I do have is I tried to update the workbench image to 11.04 but get parse errors on the scripts that u setup (i.e startup.continue)
I was wondering if you have tried to run workbench on new version of ubuntu.
And thank you for all the hard work
Dear Chris,
I have installed GNS3 WB 5.8 and I m getting the below error when i test the qemu.
“Failed to start qemu”
What could be the problem?
Adam
Adam, I don’t think I installed qemu when I installed GNS3 on WB because I was aiming at CCNA level. But if you look you should be able to find help on how to install qemu. (Currenly I’m on holidays with just an ipad, so I can’t help you much)
Hi rednectar!Great Job,thanks for our gns3 workbench,i studying for cert ccna and it is great!…
So i have a macbook pro with VMWARE Fusion and when i try to connect cloud with interface of vmware(vmnet 1) gns3 appears this message:
206 unable to create generic ethernet NIO
so i search on google and is a frequently problem but i’m not able to resolve this error…
How you do?I saw that you have a macbook with vmware..
Thnaks a lot!
Hi Max,
I have tried to recreate your problem but all goes well for me – check this video and tell me if you are doing anything different [You will probably need to watch the video in 720p to be able to read the screen]
Chris
Chris,
I came across your post in the GNS3 forum concerning “lost icons”. I too have noticed the icons are lost if I use the user account to start GNS3. If I start GNS3 with the root account the icons appear. Did you ever receive any feedback on this issue? Thanks!
-Mike
Mike,
That problem did get fixed, I just can’t remember exactly what the solution was. I think it was something to do with rights to the working directory (or temp directory or something like that). This is why I need a memory backup – wish I had have posted the answer when I found it!
Anybody any idea how to enable remote desktop connectivity to the GNS3 server?
I have it running on an ESXi host and can ping it no problem, I can remotely connect to routers running on it no problem, however when I try to VNC I get connection refused?
I have enabled the Remote Desktop
Any Ideas?
Have tested this on a remote server running vmware fusion and had no problem, but haven’t tried on ESXi.
A very strange thing….
When I’m running the GNS3 WorkBench image with VMWare player running on my pc (windows)
I’m able to connect GNS3 routers to the local lan….
BUT when I run the GNS3 WorkBench image on a ESXi server, It’s not possible to connect any GNS3 router to the local lan…..same config is used a the previous test…
Does anyone know how to fix that?
regards
Geo
I personally haven’t run GNS3 WB on an ESXi server, but others have. Hopefully someone will be able to help.
Hey Geo, yeah ESXi, especially when managed with a vCenter server utilizing VDS (vDistributed Switchs) greatly complicates things. But even at the most basic level (VSS, vStandard Switches) ESXi abstracts the physical nic’s away making it tricky to know what pnic is really doing what plus esxi inserts a lot of odd but useful layer 2 manipulation. With VDS it goes from tricky to downright insane but equally as useful. But it’s absolutely doable. Unfortunately the configuration of VSS vs VDS is completely different in every possible way, the only thing they share is the nomenclature of the nics vmnic and vmk. Cisco’s nexus 1000v which replaces all of VMwares layer 2 services greatly simplifies things but it’s expensive and not widely used outside of the BIG boy’s. Without knowing more about your setup I can say is that regardless of what switching your using (VSS or VDS), vlan tagging is by far the most common thing that trips people up. VMware’s switching has no concept of the native or untagged/mgt vlan (outside of not setting a vlan or leaving it at None (0). While the default native vlan on all cisco stuff is vlan 1 which I change to 4094 immediately. It’s more complex to change it from 1 but it greatly simplifies things when things get really complex with vmware integration. On the bright side, if you don’t have your arms around vlan tagging this is a perfect scenario to lay a solid foundational understanding of it. Then it’s probably VLAN encapsulation, the older cisco IOS’s mainly used in GNS3 default to ISL (cisco’s proprietary tagging) so just be sure to always explicitly use dot1q.(example #int gi0/10; #switchport trunk encapsulation dot1q). After that and if your using VDS, if frames aren’t making it through the GNS3 cloud to the real hardware go into the properties of the distributed port group you’ve assigned the gns3 cloud nic to and change “promiscuous mode” and “mac address changes” (found in the Policies -> Security section) from reject to accept. And lastly, if you’re proficent with VDS and have tried the above to no avail there’s a 99.999999% it’s a bug in ESXi’s networking that’s been addressed in a minor patch you can apply. That’s happened to me 3 or 4 times in the last 3 – 4 months.
Feel free to post more details about your setup and we’ll see what we can do.
How to fix qemu on WorkBench V5.8
1) Create directory to store files
- cd /opt/GNS3
- mkdir qemu
– cd qemu
2) Download qemu source for V0.11.0
- wget http://download/savannah.gnu.org/releases/qemu/qemu-0.11.0.tar.gz
3) unpack the qemu source archive
- tar -zxvf qemu-0.11.0.tar.gz
4) set working directory to qemu source directory
- cd qemu-0.11.0
5) download olive patch
- wget -O qemu-0.11.0-olive.patch http://sourceforge.net/projects/gns-3/files/Qemu/qemu-0.11.0-olive.patch/download
6) install patch command on Workbench
- apt-get install patch
7) apply the olive patch to qemu
- patch -pl -i qemu-0.11.0-olive.patch
8) install libraries need to compile qemu
- apt-get install libncurses5-dev zliblg-dev libsdl-dev libpcap-dev
9) configure the make command for WorkBench
- ./configure –target-list=i386-softmmu
10) Compile the qemu source
- make
11) Install the new qemu program
- make install
12) Change the parameters for qemu in GNS3 to the /usr/local/bin directory using the GUI.
13) Test should now work.
Thanks Mike. I’ll turn this into a post later (with due credit to you) so it will be easier for others to find
hi
I have server hp dl380 g5 and have 3 hp nic quad port nic cards and in that server I install esxi 5.1 ,
I have also 4 switches 3560 and what to connect gns3 inside esxi to the reall switches through the nics . I install window 7 inside the esxi as a host with gns3 but till now I couldnt manage to make a connection between gns3 routers and the switches
any help will be appreciated
Hey Kadhim, that’s a tricky setup and while it works it’s not straight forward and it behaves oddly, especially on the gns3 host. Are you wanting to extend layer 2 and all of CIsco’s yummy layer 2 services (cdp/lldp, vtp, etc) or do you want a layer 3 boundary between gns3 and ur physical architecture?
How to convert GNS3WB to ESXi from ESXi command line:
Get the WorkBench to your esxi storage via scp or vsphere client
ssh into esxi server or access the console with Alt-F1 over ipmi1.5/2 or from local keyboard and cd into the WB folder
If they’re still zipped do:
for i in *;do unzip “$i”;done
1. Convert and consolidate VMDK’s from Workstation to thin provisioning (in this example)
/vmfs/volumes/OpenFiler/GNS3WB58 # vmkfstools -i ‘GNS3 WorkBench.vmdk’ -d thin ‘GNS3 WorkBenchC.vmdk’
2. Edit vmxf file to reflect the new consolidated vmdk name
/vmfs/volumes/OpenFiler/GNS3WB58 # sed -i s/WorkBench.vmdk/WorkBenchC.vmdk/ ‘GNS3 WorkBench.vmx’
2.1 (Optional) You can delete all the uneeded vmdk files now if you want
/vmfs/volumes/OpenFiler/GNS3WB58 # rm GNS3\ WorkBench-f* GNS3\ WorkBench.vmdk
3. Through vSphere client delete all 3 nics
4. Through vSphere client add 3 “VMXNET 3″ nics
Then start up the vm and enjoy
You can probably copy and paste below:
vmkfstools -i ‘GNS3 WorkBench.vmdk’ -d thin ‘GNS3 WorkBenchC.vmdk’
sed -i s/WorkBench.vmdk/WorkBenchC.vmdk/ ‘GNS3 WorkBench.vmx’
rm GNS3\ WorkBench-f* GNS3\ WorkBench.vmdk
Thanks for the info. Haven’t tested it yet, but this is too good for a mere comment, I’ll publish it as a post to make it easier to find.

With esx 5.1 it disnt work for me i had to do a workaround … create a virtual machine with esx 5.0 and then use the vmware conversion tools
and then copy it back to esx 5.1 … just so you know 
Hey Patrick, I did the conversion on 5.1-799733 and the vmkfstools hasn’t changed in years so it’d be interesting to know where things fell apart for you.
question ! with 5.8 i have 16gig of ram but in ubuntu 10.10 it ‘s shows only 3gig … tried to install the PAE soft.. wont work .. if i upgrade to 11.10 all the software doesnt work ( gns , wireshark ) is that because its 32 bit ? or what r my option ?
I think you hit the nail on the head – 32 bit! Someone else has done a conversion to 64 bit – let me see if I can get him to tell us how he did it.
Thks Body ! i love your work !!!!!!! by the way !!!! many thks !!!!!
Thanks for the tip!
Another Note , i have upgrade to 11.10 ( 32 bit ) and then i was able to install PAE so i was able to use the 16 gig of ram …. but GNS , Wireshark doesnt work anymore ? is there any workaround for this .. i am not a pro with linux !!!! thks !!!
Hi
nice work but it seems that su password did work
I downloaded the GNS WB 5.6
regards
Jeff
su password is:
password
Hello Rednectar,
thx for your replied
but I tried again: su password not working
Another issue is that I’m not able to link the router to my local LAN.
You replied to Titex that it ‘s a bug on linux….I confirm that on XP, GNS3 is able to connect to the local LAN, but with GNS3 WorkBench 5.6, It wouldn’t..Do you know if it’s corrected in the new version?
For your information, I converted your vmx image to run in ESXi 5.1 and it works fine
regards
Geoffroy.

Well done. Thanks for sharing!.

Hi Chris (or maybe somebody else can help me out)
I’ve done some of the ICND1 execises but now i’m stuck at the “SDM DHCP & NAPT” , the problem is that i have to configure eth0 with an ip address 10.10.10.x/29 , i did that (10.10.10.2/255.255.255.248) but i’m unable to ping or connect to the router using 10.10.10.x network from the vm , or i don’t understand which of the NIC’s i have to configure with 10.10.10.x/29
i’ve tried the other interfaces as well but no luck
my vm interfaces are eth0 – bridged , eth1 – NAT , eth2 – Host Only
here http://pastebin.com/M7yKVM67 is my ifconfig output
TiTex,
You need to configure the IP address of your HOST PC (ie your Windows or Macintosh PC) with a 10.10.10.2 IP address. Actually, there is a quirk with Linux that doesn’t allow you to ping from your Linux to your Routers (don’t know why – see http://forum.gns3.net/topic18.html – under the heading :On Linux / Unix / OS X, when I bridge a router or switch interface to my local host I can’t ping it from my host. But this works on Windows? What gives?
I think I’ll rewrite this lab before the next release.
Ok , i’ve done it … however i had some trouble with SDM , so maybe this will help somebody else.
First install a loopback interface on your host (windows , or whatever)
http://www.windowsnetworking.com/articles_tutorials/install-microsoft-loopback-adapter-windows-xp.html
Configure the loopback interface with 10.10.10.0/29 (just don’t pick 10.10.10.1)
i’ve used 10.10.10.2 for the host (windows) and 10.10.10.3 for the guest (ubuntu gns3 workbench)
I don’t know if this is a must , but i’ve done it… edited vmware workstation networks and added a new bridged interface and selected the windows loopback interface to bridge with
I’ve edited the workbench proprieties and removed all NIC’s , then added one NIC , the one bridged with the loopback.
Started the VM , configured eth0 with 10.10.10.3/29 , started the exercise and routers , this time worked.
From my host pc , i could ping 10.10.10.1 (router’s fa0/0) , 10.10.10.3 (linux guest eth0)
As far as i know SDM it’s not installed on the router when you start it up, so i installed it on my host pc , i could connect with it to the router but some futures are not working i.e. clicking on some buttons , i’ve searched around and it looks like it’s a java incompatibility.
After this i’ve uninstalled SDM and installed CCP http://www.cisco.com/cisco/software/release.html?mdfid=281795035&softwareid=282159854&release=2.6&relind=AVAILABLE&rellifecycle=&reltype=latest , CCP worked with jre 7 and i finished the exercise
Any chance this could be converted or made available for Parallels users?
Parallels should be able to read a vmware image – I did a trial of Parallels 8 recently, and I’m sure all I did was point it to the VM I wanted opened and it converted it for me. But I did find that Parallels did screw up the display of my Ubuntu VM when I went from dual-display to single display – so I stuck with VMWare 5.
Pingback: GSN3 virtualized or Saas?
Hello,
thanks for such an awesome program.
i got a quesition:
ubuntu 10.10 is out of life, should i upgrade workbench image to newer version of just wiat for mint to come out.
all i want is to change the screen resolution. i am not that familiar with ubuntu,
thanks for help
As far as changing the screen resolution is concerned, the VM *SHOULD* resize itself to whatever screen you run it on. If you are running on VMware Player, you may have to update VMWare tools (which is a bit of a process- see this link).
Updating Ubuntu is a royal pain – maybe I should just tidy up the Lime version and release it (don’t know how much longer GNS3 0.8.4 will be) and give you a shot at that.
hey SGX
in the README file Chris is suggesting:
“This program requires a copy of a Cisco IOS image – preferably c3725-adventerprisek9-mz.124-15.T10.bin”
so that might be a hint that he used it and knows to work
P.S. you can add interfaces to any router (i think) from the configure page (right click -> configure)
have fun
Firstly, thank you for putting the effort into maintaining this fantastic resource!!
As someone currently doing my CCNA, and unfamiliar with the Cisco world, I found the biggest hurdle with GNS3 is trying to figure out working combinations of IOS images and virtual hardware in GNS3.
I dare say, other newcomers to GNS3 are also in the same boat. Any chance you could include inside your workbench/appliance a list of known working SW/HW combinations including:
(a) IOS image name
(b) Configuration parameters for the GNS3 virtual device hardware
I must have wasted half a day yesterday blundering along in the dark until I happened to find a working combination.
*** I am NOT asking for the actual IOS images, just to know what virtual GNS3 hardware is needed for, say 3 different models, with serial and ethernet interfaces.
SGX,
I feel your pain!!!!!!!!! In fact, it was this kind of difficulty that I wrote GNS3-WorkBench to try and overcome as best as I could. Unfortunately, I had to stop just short of supplying the IOS image!!!
The battle of trying to match IOS versions to hardware capabilities has been a problem for a long time. The BEST place (not a good place, but still the BEST place) to work out which image works with which hardware is the cisco website: specifically http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp (you probably have to register first)
As for the configuration parameters – again – that takes a bit of learning, and again the idea of the WorkBench is to get you started before you have to know that stuff – and when you are ready, you’ll have to read the documentation pages on the GNS3 website.
And finally – my advice is to not worry about 3 different models – just work on learning how one model works, and you’ll be able to transfer that knowledge to 90% of the remaining models. I have written the WB exercises specifically for the C3725 and ideally using c3725-adventerprisek9-mz.124-15.T10.bin – but if you can’t get this particular image, another 3725 will probably do
Thanks!

First excellent work congratulations…
you have developed a level CCNP WorkBench
Muchas gracias…
thank you very much….
The next version will have more exercises, not necessarily CCNP but some will be. And some will be CCIE level.
is there any way qemu can work???
I had same problem with installing GNS3 on Ubuntu but couldn’t make it working,….
It has been a while since I played with Qemu, I know I got it working at one stage, but it wasn’t easy. Are you using qemu to emulate an ASA or another device?
Now that Ubuntu 10.10 is end of life, any plan to upgrade this to a more recent release?
Working on a new version that uses LinuxMint (couldn’t handle Ubuntu’s new interface). Hope to release it soon after GNS3 0.8.4 is done.

Does anyone know if this can be installed on esxi 4?

I have had someone comment saying that they have installed it on ESX http://rednectar.net/gns3-workbench/gns3-workbench-install/
Also another user (stefan) in a comment above says:
Hello everyone! I am studying for Network Admin and I would love to get this up and running. I downloaded “GNS3 WorkBench-f002.vmdk.zip” and followed the installation instructions. The install instruction states:
* From that folder, open the .vmx file (double click – or open from VMWare)
The .zip didn’t come with a .vmx file, only “GNS3 WorkBench-f002.vmdk” which I cannot open in VMWare. I am using VMWare Workstation 8.
Thanks in advance for any help you can give.

Unfortunately, SourceForge only puts up one of the last files uploaded as the “latest version” – your little adventure has caused me to rewrite the README.txt on the front page!
The new README.txt says:
So if you go back to https://sourceforge.net/projects/gns3workbench/files/ – you can find the other files you need!

It is not unusual to get a message about extra byte at the beginning of a file, but what you see sounds like it is a corrupted image. I would suggest trying another image.
but that same image is easily unzipped when i just run them in GNS3, with specific routers??
Then it is probably already unzipped then!
My bad on my last, I guess the latest Ubuntu rev is 12.04LTS:-\
I am not sure if there is a limitation on your blog, but I tried to send you a message that didn’t post twice so excuse me, but I had put this reply in several sections as follows…
Sect 1.
First of all I would like to thank you for all of your efforts:-) I was able to install and use your GNS3 Workbench very easily. However, shortly after loading the unpacked IOS images that you recommended, I got an “out of hard disk space” message from Ubuntu. I researched this a bit and found the following two steps to try to remedy this by increasing the partition size, but it didn’t work for the Workbench distribution. These steps were found on the VMWare and Ubuntu websites:
Sect 2.
1) I shut down the Workbench and increased the partition size in the VMWare Virtual Machine Setting>Hard Disk (SCSI)>Utilities>Expand window. When I changed the size and clicked OK, it popped up a message saying to the effect that “you may have to increase the partition size from within the OS itself.” This was correct because I set the partition to 12Gb, but when I ran the Workbench the original 6Gb remained, but with of 6Gb free space (according to the Ubuntu Disk Utility).
Sect 3.
Any advice on how to increase the space would be greatly appreciated since I am not a Linux wizard:( If not, could you please create a new distribution with a larger partition to be able to accommodate for the IOS files and projects? I do realize and appreciate your wanting to keep this distribution small. There are other alternatives to using ZIP that you may already know about. I recommend using RAR. RAR allows you to reduce the larger files and folders into smaller chunks (in some cases it allows for file compression). Most people that download from the Internet already use it and it is supported by most programs that works with ZIP (i.e. WinZIP, WinRAR, Total Commander, etc…)
The larger distribution will add to the initial download time, but will increase the capabilities to your GNS3 Workbench for future growth.
Respectfully,
Greg P.
Howdy.. I’m downloading the code again, my first attempt to bring it into my VMware esxi5 cluster didn’t work. Do you know if it will run under vCenter?
If anyone is finding my comment about ESXi 5, search this page for comments about the “converter.” That will solve the problem. It runs, very well.
Thank you Chris for your quick reply and the link.Everything is working fine now and I must say the inclusion of gns3vault labs works just like cherry on the icing.Great Work.
Thanks

Chris I’ve tried to download gns3 workbench and all the files listed in the 5.8 folder have downloaded without any problem but GNS3 WorkBench-f001.vmdk.zip downloads only 703 mb opposed to 737 mb as listed although the download finishes without any errors but when I try to extract the zip it fails on 99% with a CRC error.I’ve download it with opera,chrome&IE and also with download manager but its the same story every time.I really need it to prepare for my CCNA.So could you please see into the matter as soon as possible.
Thanks
Aashish
AAshish, Not much I can do about sourceforge, but I have uploaded a copy to http://www.4shared.com/zip/k7uSLuQY/GNS3_WorkBench-f001vmdk.html. You might have more luck downloading from there.
Thanks Chris.I’m downloading it now will reply when it completes.
Thanks

Can’t get it to open. Right after I double click the vmdk file, I get a “line 1: Syntax error.”
Windows 7 Home Premium, 64-bit 6.1.7601, Service Pack 1
VMWare Player version 4.0.3 build-703057
Error while opening the virtual machine: File “C:\…\GNS3 WorkBench-f002.vmdk” line 1: Syntax error.
There are 6 zip files you have to copy and expand – it just so happens that the GNS3 WorkBench-f002.vmdk was the last one uploaded and so shows are “THE” file to download on sourceforge.
To install successfully, you will need to download and expand:
GNS3 WorkBench-f001.vmdk.zip
GNS3 WorkBench-f002.vmdk.zip

Thanks for this great software, it has helped me a lot. Ik have one question, is it possible to use pagent IOS in the workbench. Would be nice if we were able to generate some traffic on the network.
Thanks!
I haven’t tried, but this link may help http://alloytm.com/2011/07/07/install-cisco-pagent-ios-tgn-traffic-generator-on-gns3/

I should add that Mint is based on Ubuntu minus Unity.
I see you went with Ubuntu 10.10. I am guessing you do not like the Unity interface on the newer versions of Ubuntu. Have you considered going with Mint since it uses the native Gnome windowing system?
First impression of Unity interface = sucks However, I’ve just downloaded 12.04 and am determined to have another look at it, but in light of your suggestion I might check Mint first. I’m also going to have a look at a couple of other distros (Suggestions welcome) C

Hello,
First I would like to thank rednectar for all he has already done until now, I know that you already been thanked a lot but I guess it’s in order for all of your efforts.
Am trying to use GNS3 without the scenarios but it’s asking me for a password to access the application. can you tell me what is it?
A google search for “gns3 workbench password” should lead you to this page: http://rednectar.net/gns3-workbench/gns3-workbench-default-password/
Which tells you the only password you need is…
password
Thankyou Rednectar, I have learned how to fix afew things already. I think it would be best instead of having a user, everything is done via the root user, I read that the 209 error is caused because I am not logged in as root.
Hello, I really like gns3 on linux, runs better in a vm than on windows itself. Also having it all pre setup is wonderful apart from having to supply your own IOS’s. Before you release 5.8, I would like you to include some more features.
Install a flash player for firefox.
Provide the root password, every time I tried to su, I get authentication error.
Setup some of the qemu’s like linux tinycore etc, I have been unable to get any working I get 209 error.
include some other software like ftp’s, subnet calculators etc etc.
Also have firefox setup with a alot of good networking links.
Also have routers setup with more modules rather than just fa0/0 & fa0/1, I have been unable to work out how to add modules to routers.
Run a compressed file system. Also do not have the vmdk drive span, most people use filesystems that can support 2gb+ files. Not a big issue but it is nicer.
Thankyou
Thanks for your suggestions John. I’ll do my best! But I can help you out with the root password. It is simply the word password. Use the command sudo su – to log in as root.
Unfortunately, being a network engineer myself — Im totally lost in linux and wouldn’t be able to give you a hand on that one
. One of the reasons I like so much your distro is that you don’t have to have any linux understanding and still be able to just focus on the cisco simulation. Thanks anyway and happy holidays, Chris!
Thank you very much, sir! Workbench rocks! And you must be the real deal, for sharing all this with us, the mortals!
I had only one problem – couldn’t get QEMU running; under the qemu pref – second line (below the qemuwrapper) – where it says ‘qemu’, and the third line with the qemu image are both missing from the distro. The path points to nowhere and the linux cannot locate them anywhere. Not a big deal, just wont be able to use ASA, still would be nice if somebody knows a solution. Unfortunately, I’m totally lost in Linux and cannot have QUEMU recompiled or the like.
Keep up the great work!
When I did GNS3WB I concentrated on the tools that would be needed for CCNA. I’m actually going through the same pain now trying to get the next release ready – that is, trying to get QEMU to work on the rather old 10.10 Ubuntu. Right now I’m not able to work on GNS3WB for a couple of weeks – if you happen to fins a solution before then, please let me know! (sorry for the totally non-helpful answer)
Chris
Your work …Excellent…
The service and opportunity you’ve provide …outstanding…
Your intelligent and timely response to your users and the clean, well designed web interface…
…isn’t it just a bit sad that Cisco doesn’t see the value in promoting the use of GNS3 and providing an “educational” set of IOS’s…so that aspiring, (potential) future advocates/representatives of their Market Share Industry, (the true promoters of Cisco’s product line and services) have a better tool, and thus a better understanding to carry into their careers… sorry…I almost digressed into a rant…
As I was saying….
Well done…
…and I ain’t easy…I can count the comments I’ve left on websites on one hand…(now, one hand and a finger of the other).

I’d love to be able to add the IOS to complete the package, but I guess I better not push the boundaries!
Thanks for your kind comments.
Dear Mr. rednectar. I apologize my behavior earlier, it is maybe due to the frustration I have encountered while downloading your software and due to my passion of learning new things relevant to what your software offer. I would like to request the removal of my post and my name on this website so that I can forget all the disappointment I have encountered while trying to posses your software. Thanks for your consideration.
Rednectar: any updates to workbench?
I am busily getting the GNS3 0.8.2 update installed, plus a bunch of new labs. Hope to have it up within a week
cool, any ccnp labs in the pipeline?
I cant seem to open the console for the router within gns3 have I done something wrong?
and youve done an awesome job! incredible!
Sammy, this is a fairly common problem so I posted an answer here. http://rednectar.net/2012/03/08/problem-cant-get-console-to-open-in-gns3-workbench/
Hi,
I can boot this into VMware player: 4.0.2 build-591240 no problems. This host OS is 64bit Ubuntu 11.x
Will GNS Workbench be released in a Virtualbox compatible version by chance?
Hello Mr. rednectar. You have already told about making download on torrent basis. Just like some of the guys who was dying to grab the workbench… I was also one of them. I’m having problem downloading it at sourceforge. Using Free Download Manager I got stuck at 99% download and all it needs was around 20 mb of files left. Until all my prepaid connection was consumed still I was waiting for that 20 mb to fire up and got no result. I also tried Kget, Uget, DownThemAll and flashgot but all was a failure. Even the Firefox download manager didn’t succeed. Can you imagine the frustration that I have after consuming 24 hours trying to get that file while I can download the same amount of file around three hours on a torrent site? Can you please do something about it? Tell Mr. Cris to upload it to a dedicated torrent site?
I did have a torrent running once before – I’ll give it another shot – although I won’t get a chance to try until next week.
Hello rednectar. A pleasant day to you. You know what? I forgot to tell you last time that I have successfully download GNS3 Workbench at 4shared and I am soooo happy about it even though it was a rar files. It was dissected so anybody who has a low bandwidth internet can download it slowly piece by piece. Unfortunately to my surprise it was encrypted. It was asking for a password. Damn… my heart broke because I am still halfway to my goal. I don’t know why you have upload that workbench to sourceforge where it cannot support low bandwidth download connection. I tried to please the guy who upload it and begged for the password but until now he was not responding. Probably wanting some compensation to his upload where I cannot provide. Well I think I have come to the point where I must gave up hoping to download your workbench. I guess it is only intended for the rich fellows in your circle. Best regards.
Hello the persistent rezolt is back for another alternative download. Anybody here can point me to GNS3 download site that can support low bandwidth connection or can support DownThemAll or Free Download Manager. This tool I mention is a solution software for those who have low bandwidth connection. The problem though is that if you use it to sourceforge.net the server will definitely times out after some time.
Try http://www.4shared.com/zip/smMAEVbR/gns3_workbench_56.html
Thank you very much Mr. Chris for the upload to 4shared. Since last night I was trying to download it using DownThemAll, flashgot using Firefox built-in browser and Wget as well as the Firefox’s direct “save at” button but to no success. The problem is the server suddenly times out and it stops sending file fragments. I really don’t know why. I also tried Transmission last night but it only start this morning around 6 or 7 +8 UTC. The torrent works but I was connected to only 2 peers which is quite very slow. Now that we are in the 4shared website does Mr. Chris knows about the guy who upload the same application in rar files? I believe he was using odin69 as his pen name. The creator of GNS3 workbench created it for free but he was making fortune out of it. Anyway my download is around 70 % now, I hope it’ll end before my 24 hour prepaid load runs out. More power to you Mr. Chris and Mr. rednectar. I just hope you could split the file in 4 and upload it again so it can be downloaded easily and without a password.
Red,
Great work here! One problem, I need to know how to get the IOS images I need?
I get this message when I click on the ICND1 or 2 labs:
…before you can enjoy using GNS3, you have to have an IOS image for a Cisco 3725, 2600 or 2691 Router stored in the /opt/GNS3/IOS directory.
Can anyone link me to an FTP site where I can get these images?
HELP!!! I already scheduled my ICND1 test for next month and really need the practice!
Sorry Big AL – there’s no way I can legally give anyone Cisco IOS images. There may be others who have less to loose than I do who may be able to help. All I can say is that to date I have never heard of anyone being sued by Cisco for using IOS on GNS3.
Hi Chris,
Ignore my last post – apart from the bit that says how impressed I am with the appliance – I appear to have been suffering from a combination of stupidity and laziness. Both of which have now been resolved through judicious application of caffeine.
Keep up the good work,
Dave.
No worries. And thanks for the accolades.
OK Chris,
Actually, one more item and I should be all set! I’m trying to use the Qemu Appliances with WB5.6 — but it looks like qemu is not included in this release? “Failed to start qemu” when I run the test button. Anything I’m overlooking? I searched around and I see some of your older posts indicating that it’s not bundled in to some versions? Is it supposed to be in this latest one?
I have the qemu appliances working great on my Host (Win7) and on a VMware Server2K8 R2 install — this is pretty cool stuff — especially the Linux TinyCore which comes up in a graphical screen! (Perfect for a Linux noob like myself ;o) I also have the VirtualBox appliances running on my Host machine.
I went into Qemu prefs, but I can’t find a path for qemu and qemu-img. So, how would I go about getting this to work? Am I just missing the path?
Jerry
You are correct – I did not install qemu on the WB5.6 release – it was aimed at just things you’d need for CCNA.
When GNS3 0.8.2 is released, I’ll release a new version of WB with qemu and virtualbox pre-installed
CW
Turns out it’s not necessary to do any bridging from vmnetcfg! Finally sorted everything out, and it’s working perfectly. What confused me (and ultimately helped me!) was configuring 3 variations of GNS3. Maybe this will help others out there. The MS Loopback stuff is tricky.
On my Host PC (Win7), I added the Microsoft Loopback adapter. Running GNS3 here, a Cloud sees ALL of the Host’s interfaces — LAC, LAC2, plus the VMware adapters, and VBox adapter! I configure LAC2 Loopback as: 192.168.254.10 /24 PLUS gateway 192.168.254.1 There is plenty of conflicting info on whether a gateway should be specified, but I found the only way to work is to add the gateway setting. I connect this as a Cloud /MSloopback interface to a router port at 192.168.254.1 in GNS3.
Next case, I have a VM running Server2K8 R2, installed a Loopback (LAC2) here also, and when running GNS3 here, the Cloud ONLY sees this VM’s virtual adapters LAC and LAC2! I configured it as 192.168.254.100 /24 PLUS gateway 192.168.254.1 This VM doesn’t see the original Host PC Loopback, nor the VMware adapters. I connect this Cloud loopback the same way, to a router port at 192,168.254.1 in this GNS3.
Now — the trick — in both cases you have to go the PC Command prompt as Administrator, and add in a route back to the other ports of the router you’re connected to! For example, if the other port is 192.168.2.1, on your console,
>route add 192.168.2.0 mask 255.255.255.0 192.168.254.1 -p
This tip came from some excellent videos from Keith Barker at
http://www.youtube.com/watch?v=U91PgdBeKSQ
His video doesn’t use a gateway setting, but again, in my case it would not work unless I have the gateway specified. You can now ping from your console, through the GNS3 virtual router network in either one of these Microsoft environments.
Lastly, with the Ubuntu Workbench 5.6 VM, it finally dawned on me…. duh! Linux doesn’t see the MS loopback at all, nor does it need to! I went back and followed your 3 part series step by step, and everything worked perfectly, once I used the correct address. I changed eth0 to be a NAT config, instead of bridged, and received an IP of 192.168.80.138. In your “1 Router (reset Lab)” dhcp assigned the router port to 192.168.80.143 That’s what I was missing! Now, from my Host PC (Win7) console, I can ping, telnet, and SDM to 192.168.80.143, and Life is Good!
Jerry
Well done. Thanks for the fine explanation which may help others.
CW
Great! Option 2 does work as you explained. If I set the 3 VMware adapters to NAT, NAT, Host-Only, I do get an Internet connection with Firefox. But very strangely, it doesn’t work right after the bootup! I found that if I go to Konsole and “sudo dhclient eth0″ —- it then works immediately. I would have thought that doing a startup would have reset all the IP settings, but something stays stuck. Anyway, I then tried the Cloud configured to eth0, setup a router with a dhcp interface, and a default route, and voila! I’m pinging public Internet addresses. I can capture these packets with WireShark (although I had to change the default Capture launch preferences to ( tail –bytes=+0 -f %c | wireshark -k -i – ) I also bumped the RAM to 2GB for the VM, and removed the Shared Folder link that pointed to your user account ;o)
Now, the last bit to figure out…… getting the Loopback to work. I’m probably missing something here. I configure a Cloud with lo interface. Connect it to a router, but what address to use to connect back to the Host? lo shows as 127.0.0.1
Here’s my setup: Host PC runs Win7 x64, Q6700, 8GB RAM. Network has 1 Ethernet card as L.A.C, and Microsoft Loopback adapter on L.A.C.2, and the VM adapters. Cable modem connects directly to LAC, only 1 IP address. I configured the Microsoft Loopback as 192.168.254.10 /24 + G.W. 192.168.254.1 Soooooo, I should be able to use a GNS router address of 192.168.254.1, right? From Konsole, I can ping 192.168.254.10. But from the GNS router, nothing comes back when I ping 192.168.254.10, and likewise nothing on the Host PC when I ping 192.168.254.1 On Win7, I turned the FW off, no difference. I’m stuck here.
I have another VM running Server2K8 R2, and installed the “All in one beta 0.8.2 GNS” on it, and added a Loopback Adapter to it. (The equivalent of your lo ?) But I didn’t use 127.0.0.1 for the address, I used 192.168.254.100, and it works great! From within GNS, routers set as 192.168.254.1 can ping back to 192.168.254.100. What do you make of it Chris, do I need some address other than 127.0.0.1 on lo, or something I’m missing? Thanks again, Jerry
I’m not much help here – I’ve never played with the loopback interface – I know you need it for some Windows things, but I’ve always used Linux or OS X so haven’t bothered.
However, if I understand you correctly, you want your GNS3 Router (running in the Guest VM) to be able to connect to the loopback adapter of your Host PC – which is Local Area Connection 2.
What you will need to do is set up a bridged connection between your LAC2 and one of the virtual interfaces on the Guest OS – using the vmnetcfg.exe program you already know about.
The bridged connection will (probably) end up being eth1 or eth2 in Ubuntu, and in GNS3 you will need to link your cloud to the correct ethx
HTH
Chris,
Thanks for an outstanding project, I’m sure everyone understands and appreciates the time and work that went into creating Workbench. Your explanation and examples about VMnetcfg and the VMware adapters are the best I’ve seen — I think I’ve finally got it right now!
I do have an issue, and I’ll try to be succinct here — I don’t have a wireless router, I connect directly to a cable modem. It only hands out one IP address, so I think you can see where this is going….. eth0 never gets an address, and ifconfig shows eth0:avahi as 169.254.x.y Now, at first I thought I had all the network settings messed up, but I’m using your standard build with VMware player using the 3 adapters as Bridged, NAT, Host-only. Through lots of trial and error, I found that I can ping public Internet addresses immediately after booting up, but Firefox will not connect to any websites. However, after about 20 minutes or so, Firefox works perfectly! Must be using the NAT adapter, but I don’t know why it takes so long to start working. DNS issues?
I can see that your entire setup is dependent on having a separate router that hands out an IP to the host machine and to the Bridged eth0 interface. Can you suggest a way to get this to work with just a cable modem? eth0 affects the Internet connection, Wireshark captures, and GNS3 connecting to the Host PC. It would no doubt work fine if I had a wireless router, but there must be a lot of others out there that give this a try and run into the same problem with cable modems!
Thanks for any advice, Jerry
Thanks for the kind words Jerry.
You seem to have worked out that when the VM finally worked, it must have been using the NAT adapter. Why it took 20 mins is another issue. It could be that your Guest OS (Ubuntu/GNS3 WorkBench I assume) had the primary adapter set to “Auto Bridged” – I have seen this cause a few similar problems, but without the setup in front of me I can’t come up with anything better.
In my explanation of the adapters, I did indeed assume that you would be using an external router rather than using a USB connected modem. Now I’ve never used a cable modem that didn’t have an Ethernet interface, so I’m not entirely sure how the cable modem interfaces with the PC, but I’m going to take a stab and assume it is like a 3G modem, which gives you an additional interface on your (Host) PC – “Local Area Connection 2″ or something similar. The problem is that if you bridge this interface to the Guest, then you’ll need to get another IP address from your service provider – which of course they are not going to give you!
As for getting it to work, I need to know exactly what you are trying to achieve.
1. Do you just want your VM to have access to web pages and the internet in general?
2. Do you want to have GNS3 routers running on the Guest (GNS3 WB) accessing the internet interface of the host PC?
If you only want (1) then set your first Virtual interface on the Guest (GNS3 WB) to be NAT rather than Bridged. To do this in VMWare Player, go to the VMWare Player menu->Removable Devices->Adapters->[1st adapter]->NAT
Your eth0 interface of your Guest (GNS3 WB) should get allocated an IP address something like 192.168.x.x and a default gateway of 192.168.x.2 and your Host PC is now acting as a NAT router between your Guest OS and the internet.
If you want (2) as well, probably the easiest way is to create clouds in GNS3 WorkBench that link to eth0 of your Ubuntu. Connect the cloud interface to a GNS3 router – say f0/0 on R1. Now for an IP address for f0/0 on R1 – use ip address dhcp and it should pick up an ip address from your Host PC. Also on R1 you will want to add a default route to 192.168.x.2, the same as your Guest OS.
I know this is a bit sketchy – I’m a bit pushed for time at the moment, but let me know if you need more detail.
I know version 5.6 is using 10.10, but can we do a distro upgrade to 11.10 without breaking anything?
Also, excellent work Red. Really appreciate the time you have put into this product. Keep up the great work.
In theory there should be no problem. Make a copy of the VM before you start so that if it all fails you can go back. I don’t like 11.10 personally (maybe I haven’t tried hard enough) but am looking at it for the next release which will be after GNS3 0.8.2 is released.
UPDATE: I was NOT able to update to 11.04 per the update tool. The VM does not have enough disk space to update. I attempted to extend one of the partitions, but Gparted would not allow it and I didn’t want to create another separate partition. ah well….least I tried.
Fixed size disk seems to be causing a few problems. GNS3 v0.8.2 is in beta testing now, when it is released I’ll release a new GNS3 WorkBench, but probably still on Ubuntu 10.10, but with an expandable disk size.
Looks like I solved my own issue. I forgot the ‘>’ in my syntax. All is well now;-)
lol! I made exactly the same mistake myself yesterday! That little redirect symbol makes all the difference.
unzip -p c2691-adventerprisek9-mz.124-15.T14.bin > c2691-adventerprisek9-mz.124-15.T14.image
Has anyone else has an issue unzipping a IOS file in 5.6? I just attempted to unzip an IOS image for the 2691 router and it does not complete. It states that the file names do not match. the command I used was:
unzip -p c2691-adventerprisek9-mz.124-15.T14.bin c2691-adventerprisek9-mz.124-15.T14.image
I followed the syntax per the instructions.
Hi,
I love to see this come together with JUNOS router… I hope to see one. Anyway thank you and this is very good effort. Good Job.
Maybe one day when I get a spare hour or two…….
Brilliant work Chris, Thanks for sharing this excellent tool with us. BTW, I was able to load the PIX image and it seems working fine with no issue.
Joe
Thanks Joel. Good luck with your studies. I’ve returned the link
CW
Excellent work Chris. I’ve linked your site on my Cisco study blog under the downloads sections as it was a great help during my CCNA studies. I hope others can benefit from it as well.
–Joel
Hi Thank you for an absolute outstanding CCNA Setup, GNS3 WorkBench is a god send for sure.
I have a question about one of your ICND2 exercise/labs which is accessed from the desktop ICND2 icon (ICND2 Configuration Test), your solution lists ip address not even in the configuration of the router, Am I missing something???
MYPOOL 198.18.32.65 198.18.32.70 netmask 255.255.255.248
AGAIN Thanks for the WorkBench
I’ll check it out tonight!
OK – finally got round to checking this out (sorry for the delay)
First, lets start with the question – perhaps not worded very elegantly, but:
“The Router ISP has given you six public IP addresses in the
198.18.32.65 – 198.18.32.70/29 range.”
These are public addresses, and are the addresses that must be put into the pool – and a 29 bit mask equates to 255.255.255.248; hence the solution says:
MYPOOL 198.18.32.65 198.18.32.70 netmask 255.255.255.248
So long as the service provider believes that the 198.18.32.64/29 address range on router 1, there is no necessity for router 1 to have any interfaces configured with IPs in that range – the NAT will still work just fine.
All clear now?
FYI – The gns3.net link is misspelt on your last post
Thanks for the tip! I think that mistake has been there since I first put the page up nearly a year ago! I’ve fixed it now!
Guys
I have gns3 workbench installed on ESXI 4.1, I need to be able VNC directly to workbench, usually if I need to connect remotely I either enable VNC within ubuntu or I install xinetd and install VNC as a service. I have tried to enable VNC with workbench but to set a password it needs root privileges
however the password password does not work. Any ideas what the work around is?
Thanks
Matt
I had thought that vnc remote desktop (vino) had already been enabled, but alas, as you found out, this is not the case. All the options are turned on (System->Preferences->Remote Desktop) but it sadly doesn’t work. I’ve just played with it for an hour, no luck either. Here’s a call to anyone else out there who may be able to help – please post your method.
Hi,
have you solved the VCN issue? I am running your GNS WB on an ESX 4.1 server. I would like to connect via VNC to this machine but it is not working. Under the remote desktop config is says: “Your network is reachable only over the local network. Others can access your computer using the address LOCALHOST”.
Why only localhost? How can I edit this?
I’m not sure what the problem is. I don’t have ESX, so haven’t been able to test, but I know other have done so. I’ve passed your problem on to someone who HAS got WB working under ESX4.1, hopefully they can help.
can someone please forward the link to the GNS3 workbench on skd.dks@gmail.com,
if its can be in multipart that will be much beneficial as single link can lead to errors.
Please do send me.
Thanks,
Dave
Dave,
The link (as shown on the top of this page) is http://sourceforge.net/projects/gns3workbench/files/v5.6/GNS3%20WorkBench%205.6.zip/download but it is a BIG file, and I appreciate that if you have limited bandwidth or an intermittent connection it might be difficult to download. I’ve thought about putting up a torrent, so if you’d like me to do that let me know – via gmail. (ie send it to rednectar.chris)
Hi Devinder ,
I have faced this issue three times before , then I used this free software to let the Workbench gets download . You may install it and then try to download the workbench from Chris link again .

Yesterday I finished the first half of the article that I promised to write, (http://rednectar.net/2011/07/20/vmware-interfaces-tutorial/). I’m about to start the bit that tells you how to link your Ubuntu adapters to a) your Host PC and b) the GNS3 topology.
hi,
one more problem is that when i suppose to ping router from topology of gns3 in ubutu to the eth0 of this OS i couldn’t be able to communicate and got a reply the address is unreachable i have already ask this question bt this time i have explain my problem clearly .so do u have any solution for this ????
saksham – I’ve added a second installment – this may be the key to understanding your problem – I’ve still got more to do though! Check out my latest post.
i have i problem i couldn’t be able to ping router with the gns3 workbench o.s eth0 ?
saksham,
I actually started writing an article last night about how VMWare and all the interfaces work together (with an aim to making it easier to get the SDM labs working more easily) – it will also be helpful to you. Keep watching these pages, I should finish it this week.

hi Chris,
it worked
can u tell watz d max numbers of routers which can be started in workbench
after applying the idle value
regards
Rishi
Hi Rishi
The maximum number of routers will be determined by the processing power of the host PC, and the memory allocated to the Virtual Machine.
If you shutdown the virtual machine, and edit the Virtual Machine Settings, you can allocate more RAM if you wish (but not more than what you can spare from the host PC)
I have run up to 15 routers happily on GNS3 WorkBench with 4GB RAM running on a MacBook Pro host with 8GB RAM and a 2.8GHz Intel Core Duo.

Hi Chris,
I installed Ubuntu 10.10
1. removed unwanted packages and Updated the remaining packages
2. Installed GNS3 0.7.4 with Dynamips 0.2.8 RC3 community version
3. Used VPCS 0.21a
4. Installed Konsole
5. Set the new IdlePC values
6. I will set up ASA and Pemu
Now i can start upto 8 routers with 1024 RAM allocated for the VM, Everything works fine GNS3+Routers+VPCS+Konsole, I tried your script (run.vpcs) to start VPCS it is not working for me changed trying the path to VPCS without
need your help to run VPCS, using script
Hi Sathya,
The first thing that springs to mind is that after you have copied the scripts to the new install, you will have to make them executable again.
cd /opt/GNS3/READMEs\ \&\ Scripts/WorkBench\ scripts/
chmod 755 run.vpcs
OR
In a File Browser Window, right click on the file run.vpcs and Select Properties->[Permissions]Tab->Check Execute
Repeat for all other script files
compare.configs
display.instructions
startup
And also in /opt/GNS3/READMEs & Scripts Make the following files executable
script to change firmware image
script to create version information
script to delete work-temp-backup-config files
script to kill all running dynamips instances
script to restore eth0 next reboot
And also every startup.xxxxx script in all of the directories of the /opt/GNS3/Project folder will need to be made executable. I’ve found the easiest way to do this is to navigate to the /opt/GNS3/Project folder in the File Browser, click the search icon (the magnifying glass in the top right hand corner), type startup as the search and hit enter. Now select all the files that appear (Ctrl+a should do it) then right-click on one of the files and Select Properties->[Permissions]Tab->Check Execute.
This has the effect of also marking all copies of startup.vpc and startup.1.vpc etc as executable as well, but that doesn’t matter. If you are picky, you can exclude these when you select all and before you change permissions, or you can enter a new search criteria for .vpc and mark these as non-executable in the same way. If that doesn’t help, let me know.
Chris (RedNectar)
hi,
I tried your software, It worked superb for me but i can start only 5 routers using my hardware, if you explain me how to install and set up Konsole in ubuntu 10.10. I ll set up my own and try
Hi Sathya,
I did a document called diary of tweaks made since install – or the full path is:
/opt/GNS3/READMEs & Scripts/diary of tweaks made since install
In this I describe how I installed Konsole. It is as simple as:
The whole idea of this file was to allow someone like yourself to try and repeat the install. Many of the scripts depend on the superuser password being password, so if you are doing your own install, I suggest that you stick with that. I created a user called user with the password of password.
Once you have it all installed, you should be able to copy everything from /opt/* (including subdirectories) and /home/user/Desktop and pretty much get it going.
If you’d like to record your progress, I’d love to put it here as a feature article.

hey Chris,
after gns workbech wat next r u workin on
ru plaannin somethin new in gns workbench
any thin to emulate switches wud be gre8
i hav heard switches use ASIC hardware coz of which they cant b emulated
wat r d exact scoop thrr
regards
Rish
Rish,
The guys at gns3.net do all the hard work, I just get it installed on a Virtual Machine and put a few script files around it to make it easy for people to get started. Once you get into it, you will probably create your own topologies and problems, and won’t need the WorkBench format.
So to answer your questions:
1. After GNS3 WorkBench ….? I don’t have anything specific yet. Maybe do some more certs
2. Emulating switches isn’t going to happen on gns3 as far as I know – you are right, the ASCIC hardware can’t be emulated in software (without reverse engineering). If you want switching emulation, you’ll have to go for IOU (IOS on Unix), or more specifically L2IOU, which is now operational in the CCIE exam.
The first thing you should do about the lack of L2 support is sign Greg Ferro’s petition – and to be fair Cisco have made some progress in this area with the announcement of their new learning labs which use IOU and L2IOU.
Beyond that, who knows what the future will bring? Will OpenFlow and Software-Defined Networking change the whole ballgame as far as switching/routing is concerned, especially if Google gets behind it? Will the Open vSwitch mean that we no longer need vendors like Cisco? I think not!
Enough rambling for now,
Chris (RedNectar)
i did google for L2IOU but cudnt find it newhrr
can u provide d link for it
Cheers
R
Sorry Rish – this one got lost and I didn’t notice it.
L2 IOS is internal Cisco – the best bet to get to use it is via the Cisco Learning Labs https://learningnetwork.cisco.com/thread/28739?tstart=0

it just opens firefox page and says that gns is started and now u need to download the ios
i hav already put the ios into the directory
can open gns fine from applications
but im unable to open any labs
kindly help
regards
Rishi
Rishi,
When you start a lab, the script looks for an uncompressed image following the convention that the uncompressed filename ends with .image – as recommended by Greg Anuzelli in his dynagen tutorial.. If you have put an IOS in the IOS directory, AND decompressed it AND named it xxxxxxxxxxx.image then the labs should attempt to start. Be aware that the labs all assume that the image you are using is c3725-adventerprisek9-mz.124-15.T10.image. If you are using another image, you will have to run the script /opt/GNS3/IOS/script to change firmware image.
More detailed instructions are in the GNS3 WorkBench Install article.
Good luck, hope you get it working soon.
Chris (RedNectar)
thanks a ton Chris for ur prompt response
the name of my ios was not correct i just changed it d 1 suggested by u and all labs r workin now

i;m so much used to windows that i find linux command line lil bit difficult but i want to learn it
kindly suggest some books or videos tuts which will help me out and
which linux distro shud i start with considering my beginner stage (started with ubuntu and also tried backtrack 4 but finding it difficult )
tk care & GOD Bless
Rishi
Rishi,
I’m a bit of a Linux amateur myself, but I found Ubuntu easy to install, so have spent more time with that than any other. I had a lot of experience writing DOS batch files many years ago, so managed to work my way fairly clumsily through writing a few shell scripts for Linux to get the GNS3 WorkBench operational.
But to answer your questions: 1. Which Linux distro? – Ubuntu is a good as any other I guess. 2. Which book? – None, just Google for Linux tutorial

Chris (RedNectar)
First let me say this is a great tool and I really appreciate everything you have done here. Now I have a question, because for the life of me I cannot get the cloud setup to work. I have the box running on esxi 4.0 and everything works great, but no matter what I do I cannot seem to access the SDM lab or even get ping working to gns3. Can anyone what exactly I should need to do here because from all the digging I have done it should be as simple as setting the interface in the cloud configuration.
Hi,
i’m a member of the openSUSE community, i like what you are doing and i believe we can improve it making it perfect..
i wonder if i can use your work into my future image (thinking to use susestudio) to make a preview and show you what we can do.. eventually we can continue this discussion by mail to go a little more in depth..

Hello,
1)Please advise how to increase disk space to 5GB.
2)Can you add special labs, for example, CCIE labs from ipxpert.com or ine.com labs
Hi,
1) I’m not sure of the process to increase the disk size on a Windows machine, but I believe that this article will tell you.
For Macintosh (VM Fusion), you simply follow these steps.
i) Make sure the Virtual Machine is shut down
ii) Make sure you have a backup of the VM
iii) Go to VMware Fusion -> Virtual Machine Library and select the VM
iv) Click settings
v) Click Hard Disks
vi) Move the slider or type in the new value for the size of the hard disk you want.
vii) Click Apply
2) I can’t add special labs like CCIE labs from ipexpert or ine because these labs are copyrighted.
However, if you have purchased these labs, then it would be theoretically possible to integrate these labs to GNS3 Workbench.
If someone wants to submit a network design that they’d like included (for CCIE or any other purpose) I’ll consider adding it to the next update. It would have to be an original design and guaranteed to be original.
thx for the answer
tnx for project
1)to solve problem with disk space i added another disk to virtual pc (vmware configuration). mount it and use.
Hi Dmitriy ,
Could you share the steps you used to increase the size ( adding new desk and mount the desk ) . I never done that before .
Much appreciated

Hello Chris, I saw a comment from Scott on March 10, 2011 at 08:40 stating that JunOS olive image is working fine for him, can you take help from him explaining me how this can be installed in GNS3? any link describing this process would be helpful to me
Thanks in advance

Hi out there.
I’ve some problems with ASA and IDS – maybe someone can help me?

Hi Mate,
Fantastic work!!!!!
I have made the following changes to the package;
Converted the vmdk disc from Thick(pre-allocated) to Thin and grew it to 20Gb.
Added an Olive Image for Junos, still tinkering with this got it functioning in windows GNS3 so know the olive is good
Got Pix working fine
I am now looking to upgrade the GNS version to latest so you can save mutiple ASA and JunOS builds.
Awesome work on the lab setup scripts!!! i am hoping to use your format to build some security based labs.
Thanks again
Scott
Scott,
can you please help me. I am looking for a link to get junos working with GNS3 in using windows 7
THANK YOU for such an awesome tool! One question: are we able to make this a bootable image to burn onto a CD or a USB drive? I dont have the hardware to run a vmplayer, and I’d like to be able to run my labs anywhere (starbux?) on my laptop on the weekends or when Im traveling. Would be cool if I could boot up from USB. Any plan to make this available, or a way to modify the current image to make it bootable? Thanks again for all your help!!
Great idea Pauly, and you may have just given me a solution to a problem I have where I have some PCs that don’t really have the grunt to run VMWare. I’m going to start looking at making it boot from USB right away (no guarantees). I’ll tweet when (if) its done. @readnectarchris
Red: you da man. Thanks for considering the idea. I think this distro will take off if the magic to make it USB/CD bootable can be done. Users could use 4, 8GB USB sticks with extra space to save their projects, and become even better network engineers in the process by being able to boot into it anywhere/anytime (@ the coffee shop?!). THANKS AGAIN for your miraculous efforts!!
Pauly
hehe – that’s when I get the chance – I did get as far as getting a USB bootable, but haven’t been able to move the VM to the USB. Might have to start from scratch on the USB. If you have any ideas, happy to listen.
Just found this: http://community.spiceworks.com/topic/94632 maybe I can do it with clonezilla. Have a couple of other more important things at the moment, so will have to get back to it.
I was able to perform this….Thank You!!!
Got it!
One thing I am not clear about is, within the lab don’t I need to configure the routers to allow Telnet sessions? and not just withing GNS3 but also from outside GNS3…..for example if I configure a Router with an IP of 10.x.x.x and Telnet is enabled, How Can I remote to that Router?
Excuse my ignorance…..I am really learning here!!
No – the way dynamips (the actual emulator that drives GNS3) works is that when it starts a router emulation it allocates a port to the console access – GNS3 arranges this so that port 2000 is used for the first router you add, then 2001 etc.
If you want to control access so that a password is required, do this:
line con 0
login
password Secret
Hi, Rednectar
First of all I would like to thank you for the excellent work. As a CCNA student this has become my main learning source.
Now, I have a request and would be thankful if you can assist with this.
I am trying to access my Lab from outside my home network. I know it is possible but I am not sure on how to do it.
I am using VMWare workstation 7. my host OS is Win 7 Pro but at the same time I am running Win 2008, 2003, XP on VMs. I can use whichever is easier.
Thanks in advance!!
Frank,
Good luck with your studies! There are a couple of ways of accessing your lab remotely – the one I have had most success with is where the PC running GNS3 Workbench VM is a Windows PC that can be accessed remotely using MS Remote Desktop connection – so in your case you’d have to access your host OS Win 7 Pro. Now setting up your home network to do that could be tricky, but (assuming you have a public IP address on a router that does PAT for your internal network) if you can forward traffic to port 3389 to your Win 7 Pro PC (and of course make sure your Win 7 Pro PC can accept RDP connections) then you should be able to do it. I have seen this work very successfully with one of my customers who run entire remote workshops like this using a classroom of PCs at their central office.
To elaborate – let’s assume your Win7 Pro PC has an IP address of 192.168.0.4, and your public IP address of your home ADSL/Wireless/??? router is x.x.x.x
Firstly, set up your windows PC to accept incoming Remote Desktop connections. Control Panel->System & Security-> System->Allow remote access
Next, you’d have to set up your router to forward incoming connections for TCP port 3389 to 192.168.0.4 – just how you do this will vary from router to router, and this is a skill any CCNA candidate should be able to master.
Now (from home) visit whatismyip.com to find out your public address – x.x.x.x
Finally, from your remote site, use MS RDP application (Accessories- Remote Desktop Connection) to access x.x.x.x – this should take you straight to your home Win 7 Pro PC.
An alternative option is to allow VNC access to the GNS3 Workbench desktop VM (From VMWare Workstation: VM->Settings->Options Tab->Remote Display)
Now forward TCP port 5900 on your home router to 192.168.0.4, and use some VNC viewer to access x.x.x.x – it will take you straight to the VMware Ubuntu desktop
The third alternative is to assign an IP address to the Ubuntu VM – say 192.168.0.5 (sudo ifconfig eth0 192.168.0.5 – pasword is password) .
Now configure your router to forward TCP ports 2000-2020 to 192.168.0.5.
To use this method, you’ll have to get the lab setup and started (but NO console sessions) and telnet from your remote site to x.x.x.x:2000 or x.x.x.x:2001 etc to access the console of each router. This method is best used in conjunction with one of the above.
Tip:Right click on a router ont he GNS3 window and select Change Console port to see what the current console port is!
Hey,
Thanks for the thorough explanation. Sorry I didn’t explained myself better. I am able to remote to my machine, and also I am familiar with port forwarding. Basically, I would like to Telnet to my GNS3 Labs from outside the network. Since you mentioned that I need to forward port 2000 or 2001 my question would be, Is there anything that I need to do within the GNS3 Lab for this to work…basically this is what I would do, please tell me what I am missing
1. open ports 2000 or 2001 on my router
2. assign a static 192.168.x.x to my VM Ubuntu image (I usually do bridge with a second physical NIC)
3. Configure a Lab in GNS3 and keep all my routers up and running (Live)
Now from outside the network I would Telnet to my Home GNS3 Lab using my external IP plus the open port, right?
example: 140.16.x.x:2000 ??
That’s about it Frank – and the long reply was not just for your benefit – it may help others too.
One thing to be careful of – you can’t have any console sessions active on you home GNS3 when you access remotely, otherwise the single console connection that you get with each router will have been taken by that session.
I just installed this and love how its all in one. I do however have an issue. I tried to open just the single router example but it tells me that dynamips failed. I went into the preferences and tested dynamips and it says its okay so not sure what the problem is or how to fix it. Also it shows qemu as not working if I test that.
Can anyone point me to a place to look as to how to resolve these two issues on this virtual appliance?
Hi Joshua,
This is not good news if you see that dynamips has failed. Have you tried any other labs/exercises? I’ll try and work through this with you, and of course check out the gns3.net/forum as well for tips (best way to search the forum: http://www.google.com/search?q=site:gns3.net+dynamips+failed ). I also admit that I didn’t get qemu installed on this distribution – when I built this, I was focussing on getting enough functionality for ICND1 & ICND2 candidates, so qemu wasn’t required. Maybe next version
Hi all,

Hi,
Chris Welsh
Thanks for the reply, I myself using ubuntu 10.10 with Gns30.7.3 Downloaded VPCS 20a, used ./vpcs.linux to start the vpcs and set the Lport and Rport values but i was not able to reach the other end, same problem with the linux microcore and tinycore images downloaded from GNS3 website. If you can post some info on howto use VPCS and Qemu host with GNS30.7.3 under Ubuntu. Please do it, if you can
Hi,
Chris Welsh
First of all your idea of VMware image with all the things included along with ubuntu is a best thing, but to run a VMware image along with ASA/PIX/IDS and routers qemu host, needs a high end hardware which many people cannot afford so please do some documentation work Under linux/windows on some howto’s like Qemu Host (MicroCore, TinyCore), VPCS, Junos and all if it is possible please do that for me.
Kishore – I do hope to add some ASA examples, and maybe a microcore host when I get a chance. I’m working closely with mirshni (VPCS developer) to get a new improved version of VPCs. However, I’m not intending to get into Junos just yet. My main objective in creating this VM is to help CCNA students, and in an image that I can still fit on a single DVD.
However, there is no reason why anyone else can’t add these things themselves. There are many “How To” articles and other advice on the GNS3 forum at gns3.net (do a google search for site:gns3.net howto asa). If anyone can update the image and send me the details, I’d be happy to include it.
Definitely a great package. I wouldn’t complain about the size if you were able to bundle in the ASA & PIX stuff too.
Anyway, in part 5 of the installation section, there’s a little warning about adding/changing the IOS image. Just wanted to share that I unzipped a 7200 image & put it in /opt/GNS3/IOS and it has booted up fine.
Even used Wireshark to capture a few packets running between the 7200 & 3725 just to verify that as well. Didn’t do anything fancy, just like I ripped off the shrink wrap from a SW program, installed it, and everything just worked.
Again, real nice work Chris. Regards,
KH.
Kenny – there is no reason that you can’t load any of the supported IOS images into the /opt/GNS3/IOS directory and then use them in GNS3 – the bit in part 5 “I don’t have the recommended C3725 image, but have another c3725 image or and image for a 2600 or 2691″ is about getting another image to work with all of the prepared Labs and Exercises – if you have JUST a 7200 image installed, the Labs/Exercises won’t work without modification. You need a c3725, 2600 or 2691 image because the Labs/Exercises all assume that there is are f0/0 and f0/1 interfaces, and in some cases an NM-16ESW module installed in slot 1 – which can’t be done on a 7200! Re the ASA and PIX stuff – I’d love to find the time to add some more, but like the 7200, there is no reason why you couldn’t add an ASA image and get it to work (you might need to follow a couple of the tutorials on http://www.gns3.net to get the ASA image working though.
Can ‘t connect my Ubuntu PC to GNS3 topology.
I have confugure eth0 with network 10.10.10.x ip 10.10.10.2
i ve checked cloud configuration in lab scenario. Cloud connect to etho
try to change to nio linux – nothing
a lot of trying – nothing
Can someone make small instruction how to connect virtual lab to real network for this release.

I have tested this using OS X as the host OS (running VMware Fusion) and using WinXP as the host OS (using VMware Player). I have not tested using Ubuntu as the host OS.
However, I have seen the problem you describe and have had to make sure that:
1. Your host OS has an active LAN connection ie eth0/en0/Local Area Connection (Linux/OS X/Windows) – this means you’ll probably have to plug it into a hub or switch. Give it an IP address of 10.10.10.6/29 and a default gateway of 10.10.10.1
2. Make sure your FIRST VMWare network adapter (GNS3 Workbench-Ubuntu) is eth0 (If not, run the script ot restore eth0 next reboot in the READMEs & Scripts folder)
3. Make sure your VMWare network adapter (GNS3 Workbench-Ubuntu) eth0 adapter is linked to your host PC’s ethernet connection (eth0/en0/Local Area Connection). To check this:
From VMware Fusion: Click Virtual Machine->Network Adapter->Network Adapter Settings
From VMWare Player: Virtual Machine->Removable Devices->Network Adapter->Settings – On Hardware Tab, Check the FIRST network Adapter is set to Bridged Mode
From VMWare Workstation: (Don’t know – can anyone help?)
I have also had problems where the host OS has multiple adapters – most notably my MacBook Pro loves to get confused about whether the VMWare adapter is linked to my Ethernet adapter or my AIrport (WiFi) adapter, and so I have to turn off my WiFI so that it really does link en0 to eth0. So in short – if you have multiple adapters in your host machine, you may need to disable some. I have also seen this problem with VMware Player – and with VMware player, if you have multiple adapters it is very hard to edit the actual adapter settings – you have to run vmnetcfg.exe (see this page for help:)
I have it running with ESXI 4.1 . You must convert the VMDK. The right tool is VMware vCenter Converter Standalone 4.3

Thanks for the info
i love your Projekt. I’am a Network Engineer and GNS3 works perfect for me.
Thanks for the great Projekt.
MANY Many thanks! I was just asking the same question at the bottom, when a Google search brought me back to here.. I’m converting now.. I look forward to running this and passing my CCNA.

Glad you found it!
Can I install this as a VM on ESX 4.0? It is failing when I try to power it on and does not work with Converter as well. The power on fails with following message
Module DevicePowerOn power on failed.
Unable to create virtual SCSI device for scsi0:0, ‘/vmfs/volumes/49f07a2e-a9398fbd-6e3e-001b7879227a/GNS3-WORKBENCH/GNS3-WorkBench.vmdk’
Failed to open disk scsi0:0: Unsupported or invalid disk type 8. Make sure that the disk has been imported.
I’ve never tried to install on an ESX server, but I don’t see any reason why you couldn’t. This link refers to ESX 3.5, but may apply. Let me know if it works.
Actually this link may shed a bit more light – you may need to convert the disk to a “growable” type first.
In-case you can’t use the VMWare tools.. Because this is linux and the kernel will boot and detect pretty much any hardware at startup (unlike Windows, which will typically blue screen on different hardware) I’ve done the following in the past:
1. Boot GNS3-workbench VM with an Ubuntu live CD mounted
2. Use the DD command to take a bit-copy of the VM HDD, mount and copy to a network share
3. Create a new ESXi machine, boot with an Ubuntu live CD mounted
4. Mount the network share and use the DD command to restore the bit-copy VM HDD to your new VM
Hope this helps
That is so great, thank you!

Wow – this is a brilliant idea. Thanks for this great service. How much of a performance hit do you get running this in VM compared to natively on the hardware? Is it in the 1-5% range or higher? I am going to try it out – thanks
There is a performance hit, but I haven’t done too many calculations – I was more interested in getting a “complete as possible” package together. If you have the recommended IOS, the labs have a good idle-pc value and depending on the host machine’s power you can run all the labs happily. Eg – on my MacBook Pro (8 GB RAM) I can run a GNS3 WorkBench lab with 6 routers quite happily. On an XP machine with 1.5GB RAM – forget it!
Being loaded in a Virtual Machine also adds a performance hit too – again on my PC I can run GNS3 topologies with 15 routers quite happily, but I doubt it would run so well on the Ubuntu VM (although I haven’t actually tried it).
I’d just like to show some appreciation that you’ve put all this together. I’ve been thinking of doing something similar that includes PIX/ASAs and Juniper Olives.
Thanks Adam – I did have some ASA and PIX stuff as well, but it was getting tough to fit it all in a manageable sized package. I hope to develop this site into something where you can share “add-ons” in a consistent format.
