Hello everyone,

I had a problem that when I use the GNS3-0.74 with the IOS "c2600-adventerprisek9-mz.123-26.bin" , I found that just running around 15 minutes. The dynamips-wxp.exe crash,and lose connection to my console for the routers. And I had already uncompressed the "c2600-adventerprisek9-mz.123-26.bin" to "c2600-adventerprisek9-mz.123-26.image" , but still invalid.

Please anyone can help me ?

Below is the stackdump for your reference.

Excuse me for stating the obvious, but AFTER you decompressed the image, did you change the settings under IOS images and hypervisors to point to the new image?

If that is all sweet, try running the latest 0.8.1 (Virtual Box) edition - I've noticed some improvements esp in the windows version

Thanks rednectar, I will try the latest 0.8.1 (Virtual Box) edition.

I try the latest 0.8.1 (Virtual Box) edition. But still had the same problem. I had changed the settings under IOS images and hypervisors to point to the new image.

Just around 15 minutes later..... It's crash and lose connection.

=> Error: lost communication with dynamips server 127.0.0.1
It may have crashed. Check the dynamips server output.
Exiting...

Well it looks like you are not doing too well with that image. If it were me, I'd try the following.

1. When you add the image, did you check the Cisco website (by clicking on the Check for minimum RAM requirements link) to make suer you are allocating enough RAM?
2. If so, try another image - maybe ver 12.3(26) isn't going to work!
3. See if you can make it run in Linux (you can download a Linux Virtual Machine from my blog - see in my signature)
