<br>My backup server runs a cloned setup (created with clonezilla) from an older image of my primary server (they are exactly the same hardware I might add). My backup server was out of date. I downloaded all updates, and I was still able to use freenx to get into my server. It seems that after downloading some additional recommended updates later, that's when this error started, and I'm no longer able to login to my machine. I just get a message stating authentication has failed, and the above error is logged in the system log. However, I'm not sure if updates have caused the issue. I never end my freenx session, and this might be causing problems? Before, I was able to resume just fine.<br>
<br>I'll try running sshd in debug tomorrow. Thanks so far for the help!<br><br><br><div class="gmail_quote"><div><div class="h5">On Sat, Feb 11, 2012 at 5:33 AM, <span dir="ltr"><<a href="mailto:chris@ccburton.com" target="_blank">chris@ccburton.com</a>></span> wrote:<br>

<br><tt><font>Well if you've changed machines or re-installed</font></tt>
<br><tt><font>then we start again.</font></tt>
<br>
<br>
<br><tt><font>What is the distro and patch level of this machine.</font></tt>
<br>
<br><tt><font>If it's ubuntu 10.04 like the other one</font></tt>
<br><tt><font>is it</font></tt>
<br><tt><font> desktop, with
all the software from Ubuntu</font></tt>
<br><tt><font>or</font></tt>
<br><tt><font> 10.04 server with
your own installation of</font></tt>
<br><tt><font>a GUI, browser and FireFTP</font></tt>
<br>
<br>
<br><tt><font>If it's a similar machine</font></tt>
<br><tt><font>and</font></tt>
<br><tt><font>you are still getting the same sshd segfaults</font></tt>
<br><tt><font> - what's the exact
error message from this machine</font></tt>
<br><tt><font> - any other error
messages</font></tt>
<br><tt><font> - did you always
get this segfault or what changed</font></tt>
<br><tt><font>just before it started.</font></tt>
<br><tt><font> - if you run sshd
in -d -d -d debug mode what's the</font></tt>
<br><tt><font>debug output associated with a segfault??</font></tt>
