Try a different tack. Get a root shell on the machine in question and fire up sshd in no-fork mode under strace: strace -o /tmp/ssh.trace sshd -D -p 2222 Then try to ssh into that machine on port 2222 (or whatever you choose). Assuming it fails, close down the temporary sshd and point $PAGER at /tmp/ssh.trace. The failure point will likely be about 90% of the way through the file. (The end of the file will be related to closing down sshd). -- Paul Heinlein <> heinlein at madboa.com <> http://www.madboa.com/
