Authentication Issue

[Jeff Donaldson]

So it seems the thin client console can ssh to any other server in less than a second, but if I try to ssh from the thin client console back to the ltsp server that it booted it's image from it takes 30-35 seconds. I suspect that this is hitting a timeout and causing authentication to fail. Question is, what would cause the thin client to be so slow talking back to the server it booted from? Any ideas?

 Subject: Authentication Issue

Good Afternoon, I'm having a major issue with thin client authentication. It started just after lunch time today. Authentication works fine from console and on terminal, but ssh takes a very long time to connect. I suspect it is a timeout issue with LDM. From a shell at the thin client I can ssh to any system and authenticate, however this also takes up to a minute for ssh to connect. The response at the GUI login screen is "no response from server, restarting". I've already updated the sshkeys and completely rebuilt the image but this hasn't resolved the issue. How does LDM use ssh for authentication? Is there a reason ssh would have to be routed? Any help is greatly appreciated!
