hello,
you probably need to disable dns lookup on ssh server.
simply add "UseDNS no" in /etc/ssh/sshd_config

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! Jeff
