Well, I cannot run ktrace on this particular server. I did run it on the
client, but I'm not sure that is much help.
Yup, that is what has happened. The sshd process (pid 45244 and 45265 below)
is dying (not the /usr/sbin/sshd one).
root 52394 0.0 0.0 1000 340 p0 DL+ 2:54PM 0:00.00 grep ssh
root 60244 0.0 0.1 2404 1624 ?? Ss 8:45AM 0:00.46 /usr/sbin/sshd
root 45244 0.0 0.1 5056 1840 ?? Is 2:45PM 0:00.03 sshd: jdf [priv] (sshd)
jdf 45265 0.0 0.1 5000 1848 ?? S 2:45PM 0:00.04 sshd: jdf at ttyp0 (sshd)
So, why would this be dying when I login with a Mac and not
from linux? Is the mac not pinging the server to remind it
not to doze off into unconsciousness?
