And it seems like others have encountered the same problem. And there wasn't a solution except to use teraterm or putty. Kind of sucks (but I guess the issue is Vista). If I were to install GNS3 to a VM of XP Pro on top of Vista 64, do you think that could resolve the problem? Just asking for when I migrate to Windows 7 and we have access to the virtual PC/XP.
I'm pretty sure you can get telnet working in Vista 64.
Try following steps to get console connection manually:
1. Enable telnet client in Vista (Done)
2. Build your topology in GNS3 and start router
3. type "list
" command in Dynagen console inside GNS3 and you will get output like this:=> list
Name Type State Server Console
R0 7200 running localhost:7200 2000
4. Open Command line in Windows and type telnet localhost 2000
If console opens telnet is working.
After this we can investigate this further.
