@bob – thats all you see, you need a serial interface to configure the rest.

I’m getting the same.

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?

Hey I got some problems unpacking the asa802-k8.bin.

############################################
c:\Unpack>unpack.exe –format ASA8 asa802-k8.bin
Der Befehl “gzip” ist entweder falsch geschrieben oder
konnte nicht gefunden werden.
Das System kann die angegebene Datei nicht finden.
Traceback (most recent call last):
File “unpack.py”, line 208, in
File “unpack.py”, line 146, in unpackASA8
File “shutil.pyo”, line 199, in move
File “shutil.pyo”, line 91, in copy2
File “shutil.pyo”, line 46, in copyfile
IOError: [Errno 2] No such file or directory: ‘c:\\users\\thomas\\appdata\\local
\\temp\\tmpcsbbov\\vmlinuz’
############################################

I tried all the mentioned solutions, from putting the gzip.exe in the system32 folder, adding c:\Unpack\gzip.exe to the environmental viariables or running this command in cmd “C:\Unpack>PATH=%PATH%;c:\Unpack”, but still get the same massage.

any thing i can do now ?

All guys trying ASA.
1)Download gns3 ver 7.2
2)Download Tobie’s custom initrd and kernel file from this blog.http://blog.gns3.net/2009/12/how-to-emulate-cisco-asa/comment-page-2/#comment-878
3)Install gns3
4)Dont change any path in gns3
5)Test qemu and dynamics, This test button works fine.
6)In gns3 Edit,preferences, qemu,asa select path for initrd and kernel which you downloaded already dnt change other settings.
7)Drag your ASA into gns3 and click start.
8)qemu will open dnt close it just minize it
9)Open console ASA will open in putty.
10) Follow this steps.
Cisco ASA with Multiple Security Contexts
==============================================

This is your first boot, please wait about 2 minutes for ‘disk0′ creation
and then execute the following commands inside the Linux prompt:

# cd /mnt/disk0
# /mnt/disk0/lina_monitor

Please note to use the following command under ASA to save your configs:

ciscoasa(config)# boot config disk0:/.private/startup-config
ciscoasa(config)# copy running-config disk0:/.private/startup-config

To get webvpn working, execute the following commands:

ciscoasa# mkdir disk0:/var
ciscoasa# mkdir disk0:/var/log
ciscoasa# mkdir disk0:/csco_config
ciscoasa# mkdir disk0:/csco_config/97
ciscoasa# mkdir disk0:/csco_config/97/webcontent

If you open putty and use telnet protocol, connect to localhost on port 10525, you will get this:

200-At least a module and a command must be specified

Any ideas?
