Thanks for the information Chris. I'll give it another shot, but I'm unable to even get into my machine with the nxclient from my Windows machines. The server experiences the segfault and says authentication failed. I think the problem started when I was last able to remote in and started a session where I was using Firefox and FireFTP. I closed the session (didn't terminate it), and I've not been able to get back in since.<br>
<br>I'll get you more information, and I really appreciate your help this far. <br><br><div class="gmail_quote">On Tue, Feb 14, 2012 at 6:18 AM, <span dir="ltr"><<a href="mailto:chris@ccburton.com">chris@ccburton.com</a>></span> wrote:<br>

<br></div><tt><font>If you can connect the first time and continue until</font></tt>

<br>
<br><tt><font> you should get

<br>
<br><tt><font>Try your NX connections until you get the segfault.</font></tt>
<br><tt><font>(you will need to run sshd again for each new session)</font></tt>
<br>
