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

Subject: Authentication Issue<br>
<br>
</div>

<pre><div><div class="h5">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!
