Humphrey Cheung (http://www.routergods.com/) has created a video tutorial showing how to get GNS3 WorkBench up and running.
Thanks Humphrey – but a couple of comments:
1. GNS3 WorkBench likes uncompressed images with a .image extension for the prepared exercises – in fact it checks to see if there is a “*.image” file in the IOS directory at the start of each prepared exercise. There are instructions on how tho turn a .bin file to a .image file in the IOS directory. In your example you would run the command:
unzip -p c3725-adventerprisek9-mz.124-15.T5.bin > c3725-adventerprisek9-mz.124-15.T5.image
2. The prepared exercises were prepared using the .T10 rather than the .T5, so to make your c3725-adventerprisek9-mz.124-15.T5.image work with the prepared exercises, you’d also need to run the script script to change firmware image also found in the IOS directory – it runs something like this:
Do you have a backup of your /opt/GNS3/Project directory y/n/eXit? [n]:y c3725-adventerprisek9-mz.124-15.T5.image /opt/GNS3/IOS Enter the current image - the one you need to replace (Ctrl+c to abort) [c3725-adventerprisek9-mz.124-15.T10.image]:<Enter> Enter the replacement image name (Ctrl+c to abort) [c2600-advsecurityk9-mz.124-25b.image]:c3725-adventerprisek9-mz.124-15.T5.image
If you carry out these extra two steps, then your GNS3 WorkBench will work for all the exercises too.
Router r1 is connected to the GNS3 VM via tap0 and apps like ntp, syslog and tftp within the Linux VM do work.
The 2950 switch and the laptop’s eth0 are connected with a cable. Everything else on the laptop is via wlan0.
How to connect a real 2950 switch into GNS3 when GNS3 is in a Linux VM on top of a Linux host running VM workstation?
P.S. Unrelated to the above, I’ve added ntp and tftp to the Workbench and looking to add other tools there too (e.g. mrtg, a snmp tool, etc) but after material progress with the Cisco stuff.
How to use ASA with GNS work bench. Please send me the procedure.
Thanks in advance.
Getting the ASA to work in GNS3 is not an easy task. It is not as simple as putting a copy of an image in a directory, you have to do quite a bit of work on the image first. Jeremy Grossman has posted an article at http://blog.gns3.net/2009/12/how-to-emulate-cisco-asa/ that explains the process. Note you will have to start by installing qemu. Again Jeremy has the answer at http://blog.gns3.net/2009/10/olive-juniper/2/
YOU ARE AWESOME!!!!!
