GNS3 WorkBench 5.8 ready to download

I’ve just finished uploading GNS3 WB 5.8 on Didn’t achieve everything I wanted – too hard to get it all working on Ubuntu 10.10. Especially ASA and Qemu. But it does have GNS3 0.8.2, VPCs 0.3 and a few of Rene Molenaar’s GNS3 Vault exercises built in.

Many people had problems downloading such a big file last time, so this time it is 6 zipped files. You’ll have to download all 6.

As always, comments welcome.

    If anyone is curious and wants to for performance reasons, I made a step-by-step on how to make this VM into a physical hard drive.

    There might be a mistake in one of the ICND2 labs. Specifically the EIGRP and Route Summary lab. After assigning IP addresses to interfaces on three interconnected routers, I configured EIGRP between them. When that didn’t work I tried a few different things and decided to check out the completed configs for a little help.
    That’s when I realized they are for OSPF configuration even though they are in the EIGRP folder. Is it something you can help with?

    • JJ says:

      I finished the lab so I didn’t need the configs to help me out this time. By being forced to work it out without any help, I’ve gained some knowledge of troubleshooting EIGRP!

      Also, initially it wouldn’t work with a different IOS image. I have a few similar IOS images with minor differences and this was the first time the lab loaded but for some reason EIGRP wouldn’t work. After changing the default to the one you specified, it worked flawlessly.

        There are so many variations of images that it is always hard to be sure you have an image that is going to do every thing you hope it will!

      One more thing for me to fix up in the next release….

    Hi again. I’m having problems with the interfaces in ubuntu. Whenever I assign a vmnet to the machine, it gets confusing in ubuntu. I can’t configure them for some reason. I have for instance attached vmnet3 and it shows up as eth0 in ubuntu. But I only see it by using ifconfig. When I did the only thing I thought was possible to configure it which is to edit the /etc/network/interfaces file. I uncommented the lines for the IP address, netmask, gateway, etc. But when I restarted the machine, eth0 disappeared from ifconfig and the only way to see it was by using ifconfig -a.

    I was doing the ICND1 SDM DHCP & NAPT Exercise and was trying to connect the machine’s interface to the router. Please tell me what I’m doing wrong.

      Please disregard this for I’ve since realized that I had disabled the vmnet1 interface on the host machine when that was happening.

      Still though, I haven’t been able to figure the network out. eth0 is there and gets an IPv4 address through dhcp. But it also gets an IPV6 address even after I disabled that in vmnet1.
      When I ping which is the address eth0 got through dhcp, i get an error of ‘connect: network is unreachable’.
      I tried to configure the network by going to System > Administration > Network Tools. When I select eth0 from the dropdown I first notice that it shows Scope:Link for IPV6 but not for IPV4. Also, when I click configure, there’s nothing showing up in the Wired tab. If I add the settings for eth0 it still has no effect on the network.
      Please help.

      Sorry to be rambling about on your blog. I ended up figuring out most of the issues.
      So the network is like so:
      Windows 7 host:
      Ubuntu guest VM:

      I didn’t change the R1 config yet. R1 can ping W7 but not Ubuntu. W7 can ping R1 but not Ubuntu. Ubuntu can ping W7 but not R1. Is there anything you can see that leads to this issue?

      Since W7 and R1 have connectivity, I was able to connect SDM to R1 so I was able to complete the lab.

        Hi JJ,

        I’ve been without internet for nearly a day (travelling) so didn’t see your posts until now.

        Firstly, I’m glad you were able to complete the lab, but I agree there are sometimes some strange things happen in the connectivity between VMware and the wired network. I intend to re-write that lab so that we use one of the internal interfaces (vmnet1 or vmnet8) to access the router via SDM


      • JJ says:

        Thanks for the response.

        Are you working on a new version of WorkBench?

      • rednectar says:

        Hi JJ,

        Yes – the next version will be 6.x – it will be running on Mint (an Ubuntu variation – couldn’t get Ubuntu 12 to work properly) and will be running GNS3v 0.8.4 (when it’s ready) and an updated version of VPCs.
        There will be some more labs (time consuming to construct), and I **hope** to have the basics for some ASA labs.

      • JJ says:

        That’s great!

  4. JJ says:

    Hi. Do you have instructions on how to upgrade the GNS3 in the Workbench to the latest 0.83?

    • rednectar says:

      [Have now posted this at: ]
      1. Download one of the sources from – say I downloaded it to ~/Downloads

      cd ~/Downloads

      2. unzip it


      This will create a directory called GNS3-0.8.3-src

      3. The rest is probably easiest from the file manager, but I’ll give you the commands anyway:

      3.1 Remove the following directories from /opt/GNS3

      rm -rf /opt/GNS3/docs/
      rm -rf /opt/GNS3/qemuwrapper/
      rm -rf /opt/GNS3/src
      rm -rf /opt/GNS3/vboxwrapper/

      3.2 Move the contents of ~/Downloads/GNS3-0.8.3-src to /opt/GNS3

      mv -f ~/Downloads/GNS3-0.8.3-src/* /opt/GNS3

      4. Remove the zip file you downloaded and the empty directory you created when you unzipped it

      rm -rf ~/Downloads/GNS3*

      5. The first time you run it, it will detect that you have changed versions and ask if you want to re-initialise everything. Say No
      You will then have to quit and restart if you were loading a lab.

  5. TechieXXX says:

    Indeed, it’s amazing how much work/time you’ve put into creating this great AIO appliance!!!

  6. Frank says:

    @CW – Thanks for your hard work!

  7. AA says:

    I intend to download the files and attempt to use it on my XP with 3 GB RAM, but I have c3725-adventerprisek9-mz.124-25d.image, would it work and do you recommend I spend time running it with 3GB? (my download speed is not that great so I’ve been hesitating).

    • rednectar says:

      1. the c3725-adventerprisek9-mz.124-25d.image should be just fine.
      2. I have run GNS3WB on an XP with 2GB RAM quite successfully, 3GB is even better.

      I have split the files so that it is easier for those with not so good connections to download. The biggest file is 778MB

  8. techieXXX says:

    Am re-creating these INE (i think) topologies as we speak in GNS3, don’t foresee any difficulties. Stuff like introducing an ASA or integrating physical switches is where it gets a bit hairy.!348&parid=51C847621CA88FDB!347&authkey=!AKyreMYOLGVAuBU

    p.s. first time I tried that skydrive….should work eh…

    Hi Chris Welsh.

    Thank you very much for your work…and sharing the same.
    I have tried to v2p your work …and it works.
    If you give permission then I will post the procedure here so that those who do not have VMWARE or good machine with enough RAM can use it on their older machine.

  10. techieXXX says:

    lol, yeah for CCNA it’s a more than complete solution (provided you also spend some hours on packettracer for the switching part). Been fooling around with this CCIE IOU image….cool but how exactly it this different from GNS3 other than the memory and CPU usage being less?

    • Malaya Manas says:

      You will know it when you will go through it.
      There will be no difference when someone can port all labs from rednectar into I0U.
      I am on it…

  11. Iain says:

    Just discovered this. I really hoped this kind of thing existed. Studying for CCNA and the examples and info is a dream come true. Many many thanks!

    Have it working, expanded the disk to 15Gigs via booting into gparted live, so far so good πŸ™‚ πŸ™‚ πŸ™‚ Time for a drink.

    • Frank says:

      hey, how did you expanded the disk? I did it a long time ago with gparted but I forgot.

      The problem is that when I expand the vm through vmdiskmanager, although I can see the free space in gparted, I can’t expand the disk (maybe because there is another partition between the file system partition and the free space).

      Thanks in advance!!

      • TechieXXX says:

        Download gparted-live-0.12.0-2.iso, then either mount it with daemonware or alcohol120% then inside the VMWare workstation you would change the hardware option ‘CD/DVD (IDE)’ to use either the .iso file or the physical (virtual drive letter)..I prefer the later seems to have less issues. I think what you’re trying to do is run gparted while inside the running OS and are therefore unable to make changes to the first partition. – link to screenshot of vmware

    • Frank says:

      no, I am running gparted live (not in ubuntu) I just cropped the picture to make it look nice lol but check the links for a better idea….thanks!

      gparted live

      vmware configuration

    • Frank says:

      I just figured it out…..the Linux-swap partition under the extended partition was not letting me expand the disk, I just deleted the linux-swap and the extended partition, then I was able to expand my disk (in Gparted Live).

      Thanks for helping!

      • TechieXXX says:

        lol ok, yeah you need a contiguous space in order to expand a partition, guess I was referring to my own stupidity when trying to do it within the

  13. Patrick D says:

    Your The Man !!!! Thks again !!!! Can’t wait to try it out !!!

  14. TechieXXX says:

    πŸ™‚ Downloading it now, can’t wait to see what magic you’ve done this time. Great idea to include Rene’s labs, another outstanding site.
