Thx for the response jermy i appreciate your support and now i am able to use ASA V7 in GNS3.

Hey but what about the configuration of ASA v8 image in Qemu, can you kindly help me out with this also.

Can you jot out the steps that i need to follow to setup Qemu for the ASA v8.

Once again thanks for the support.

Hi,

With an ASA v8 image you need Qemu. If you want to use an ASA v7 image then you can use GNS3.

To use an ASA 7 image with GNS3, you have to unpack it with Cisco image unpacker.

On Linux:

Code:

$ python unpack.py --format ASA7 asa724-k8.bin 
Archive:  /tmp/asa724-k8.bin.zip
inflating: /tmp/pix
ASA7 binary image successfully unpacked in asa724-k8.bin.unpacked

On Windows:

Code:

C:\Unpack>unpack.exe --format ASA7 asa724-k8.bin
Archive:  c:/docume~1/admini~1/locals~1/temp/asa724-k8.bin.zip
inflating: c:/docume~1/admini~1/locals~1/temp/pix
ASA7 binary image successfully unpacked in asa724-k8.bin.unpacked

Then you can use asa724-k8.bin.unpacked in GNS3 as a PIX image.

This is a GNS3 forum, not a Qemu forum :)

The only reason it's easy to help with Pemu is because it's intergrated with GNS3. Qemu is not. You can find more on Qemu at http://bellard.org/qemu/

Hi,

Cisco Image Unpacker can unpack an ASA8 image to be used with Qemu. There is an example in the README. I'm kind, here is a copy paste... ;)

Create a FLASH file with the follwing command: "qemu-img create FLASH 256M"

Then you can use Qemu to launch ASA:

Finally start telnet to connect on port 15000:

$telnet localhost 15000

Hi Jeremy,

I was not able to successfully unpack ASA image using the unpacker. This is the error I received during the process.

C:\Documents and Settings\>unpack.exe --format ASA7 asa724-k8.bin
'unpack.exe' is not recognized as an internal or external command,
operable program or batch file.

Can you share with me the step by step process on how to unpack successfully and where to put the ASA image file before unpacking.?

Thanks
K

@routerer you have to be in the same directory as the unpack.exe program.

@routerer you're not in the directory of the unpack program..

As an example..

Code:

C:\Documents and Settings\>unpack.exe

Should be

Code:

C:\unpack\>unpack.exe
