GNS3 : How to emulate ASA in Windows 7
In a previous tutorial, i had shown ASA emulation in Ubuntu 9.10 (Linux) . Good news is you no longer need to compile and patch Qemu (its already done for you). You just need to build initrd and linux kernel from ASA binary, set path to them in GNS3 preferences and you are all set. If you are installing in Ubuntu, follow the previous tutorial (just skip the compilation and patching section).
If you are installing GNS3 in any of Windows flavour e.g Windows XP , Windows Vista or Windows 7 , its super super easy. So, i decided not to create any video tutorials and rather just show you the screenshots so that you can set it up in less than a minute provided you have already built necessary files (initrd and linux kernel ). If you haven’t built them yet, see previous tutorial.

Here are the quick Steps:- (Click on Screenshots to enlarge Image)
NOTE : Software Versions are :
- GNS3 v0.7
- Windows 7 (64-bit) Home Premium
- ASA 8.0(2) Binary
1. Download & Install GNS3 (next , next , finish stuff)
2. Navigate to GNS3 Preferences -> Qemu -> General Settings tab and Hit Test button to make sure paths to qemuwrapper, qemu and qemu-img are set properly( default setting should work just fine)
3. Navigate to GNS3 Preferences -> Qemu -> ASA tab and set initrd and kernel paths
4. Drag and Drop ASA into workspace.
5. Start ASA and console into it .
Thats all ! Enjoy !

Uncompressing Linux… Ok, booting the kernel.
I’ve left it and left it but it’s not budging from there. Tried uninstalling and reinstalling GNS3 but no luck?

asa(config-if)# namei

For those having issues with the following:

check port number on Windows with
netstat
Hi
All those who are getting the error while trying to “no shut” the port when in interface mode

Hi,

ciscoasa# copy tftp flash:
Address or name of remote host []? 192.168.1.1

anyone else facing the same problem ?
plese guide me

I am able to do the steps mentioned above till uploading the asdm image onto flash, but then says there is an error and cant upload the image from tftp onto flash
Everyone,
use the pcnet for the NIC. Everything else should be at defaults. I am running ASA 8.0.2 with GNS 0.72. The pcnet seems to work for me; I can un-shut the interfaces and do the other interface commands.
Everything works fine…the problem starts the moment putty executes…putty freezes and goes inactive…I can only clear it in taskmanager…I’m baffled…when I test Qemu it works fine…after the linux screen appears and I execute putty it just sits there and then locksup…any ideas?
Has anyone ever figured out the answer to Phil’s last post? I’m having the same problem. I’m using GNS3 0.7.4. I installed the kernel and the initrd.gz files in their respective places and followed various installation paths ultimately ending on this forum and page. I’m using Windows 7. I even implanted the vmlinuz file in it’s respective place as well (although, it has the same distinction as the kernel file) and that didn’t work at all. The furthest that I have gotten was with the asa802.k8.initrd.gz and asa802-k8.kernel files in the respective places within the preferences tab and after I start the ASA that I have put in the environment and try to execute the console, the console comes up and nothing happens. When I press enter (humoring myself) the cursor just hops to the next line (and so on). Unlike Phil, I don’t have to initiate the task manager to exit but I’m doing everything as instructed and nothing seems to be working. Any ansers on this matter? Could it be that I just have some corrupt files?
For those having issues running ASA in Windows 7. Here it is the solution. Spent many hours going through several forums to figure this out!
1. Download “ASA IOS.RAR” from 4share.com
http://search.4shared.com/q/1/ASA%20IOS.rar
2. extract two files: asa802-k8.initrd.gz and sa802-k8.kernel. do not further extract or modify these files.
3. In GNS3(v0.7.4)->QEUM–>ASA SPECIFIC SETTINGS point to the above files. use all other default settings.
4. In QUEM General Settings->IP/HOST BINDING and EXTERNAL QUEMWRAPPER change “localhost” to 127.0.0.1
Still I am getting empty console. There is no # symbol in the console Please help me to solve
@pika
Its done I get the prompt ciscoasa>
lets see further ..
Step 4 is important
as I get prompt after doing same and reload the GNS
Thanks mike..

”
This is your first boot, please wait about 1 min and then type the following commands:
cd /mnt/disk0
/mnt/disk0/lina_monitor
Please note to use the following command under ASA to save your configs:
copy run disk0:/.private/startup-config
”

thanks in advance
200-At least a module and a command must be specified
i m getting above error please help me i m working on this from last 6 hr but no sucess ..
@pika
I got the ciscoasa prompt but it required a password when entering the privileged console
Has anyone been able to really solve the cannot get the channel issue,i have checked the hacki forum and download the stuffs from the 4shared links and tried all that stuff,please if you have kindle assit us with an how and why we get the error.
BR
@Christian: Just hit enter, there is no password set.
@delscarlett: Change the NIC of the ASA until it works. I went from e1000 to pcnet and that worked.
Personally, i’ve been stuck with not being able to write to the Qemu HDD (ASA FLASH) since 0.8x came out and haven’t found a solution that works. =-/
Spot on with this write-up, I truly think this website needs much more consideration. I’ll probably be again to read much more, thanks for that info.
Dear Freind, i had added ASA successfully, when add ASA its starting but when i open console its giving blank please help me to succeed.
