GNS3 issues

Has anyone had a problem in GNS3 where copy run start reverts your running config back to blank? Every time I do it it disappears. Sometimes doing a copy start run will bring it back but it goes away next time I copy run start. I have all the save options checked for the project too. I've reinstalled and tried 64 bit also. I don't know what's going on.

"copy run start" works like a charm for me every time in GNS3.

Are you sure you didn't accidently do something like this?

'copy run start' erases flash. wrote:

Can you provide a log of what happens when you try--

1. show run int <any-configured-interface>
2. copy run start
3. show run int <that same interface>

No idea, mate. I would say post to the GNS3 forums, but you're already on top of that.

Thanks Vet, it is so frustrating because no matter what I do it still does the same thing. Even uninstalling and reinstalling does it. But yeah, I have it posted over on GNS3 forums also, but I figured people here would be quicker to respond, and this is my favorite forum!

MrXpert

Have you tried the "export startup config" option?

What version of GNS3 are you using? There was a new release just a few weeks ago. Also, what IOS are you using? Just tested using GNS3-0.8.3 and two router images [1760 - 12.4(15)T14 AdvEnterpriseServices] and [2620xm - 12.4(25c) AdvIPServices]. Both saved the configuration.

Yeah I don't know what to do here. I wiped a whole computer clean, did a fresh install of W7, installed GNS3 all in one, still a blank running config after copy run start. I have tried a lot of different images, same on all of them. I have no idea what to do next besides give up on GNS3

If you don't get a reply on the GNS3 "General Issues" forum within 24 hours, try their Bug Report forum. From what I can see, the developers monitor that, and usually reply within a day.

Thanks Vet, I will do that. I just don't understand what can be going on. I mean it has to be something I am doing because it is working for others, plus I started fresh on a clean install and still got the same results. Installed different releases and everything. Now it won't even write once, and the strange part is if I do a show ip int br it will show my ip address is assigned to the interface, but my running config is still empty.
