Hi all,
I'm trying to use GNS3 on my laptop using an external hypervisor installed on a Ubuntu 12.04 Server.
Until now, using GNS3 (and local hypervisor) on my Windows 7 laptop goes well.

Issues are on the Ubuntu side: I tried both to install dynamips using apt-get (dynamips RC2) and downloading dynamips.bin (RC3) package.
In both cases, dynamips seemed to work well (dynamips -H 7200) and GNS3 did not rise neither alerts nor problems when creating a new topology while routers were stopped.
As I tried to start routers, depending on images I used:
- dynamips/router went into a loop (fetch error, I see an endless stream of messages both in dynamips as connecting in telnet)
- or, even no loop seems to start, I try to connect with telnet: connection seems to go well, but I'm not able to receive router prompt and sends commands.

I even try to run a simple topology (dynagen simple.net) on the Ubuntu server side, but problem remain the same.

Has anyone an idea, even how to do troubleshooting?
Is it, in your opinion, a problem related to Ubuntu server?

Thank you very much,
Simo

Hi all,
anyone can help on this topic?

I even try other two type of installation:
- GNS3 installed in a Windows 2003 Server: started dynamips on this server and connect from GNS3 installed on my Windows 7 pc. It works.
- GNS3 installed in a Ubuntu 12.04 Desktop: I can use GNS3 on Ubuntu, but if I try to connect from GNS3 installed on my Windows 7 pc, it does not work, that is, I start GNS3 on my pc, I can build a topology and start/stop routers, but if I try to telnet them, I can't do anything...see picture.


Anyone could help?

Thank you very much,
Simo
