openssh-2.5.2p2 upgrade kills master sshd, won't restart
Last modified: 2008-05-01 11:38:00 EDT
After upgrading from 2.3.0p4, I get to the syslog:
Mar 28 20:08:57 xxx sshd: Received signal 15; terminating.
Mar 28 20:08:57 xxx sshd: sshd shutdown succeeded
Mar 28 20:08:59 xxx sshd: RSA key generation succeeded
At this point, master sshd daemon has been killed and /var/run/sshd.pid
Now, 'service sshd start' won't start the daemon; no error messages are
is caused by some bug in 'daemon' code of initscripts (misdetecting current
as the master process?), as '/usr/sbin/sshd' works fine.
There are two ways the next step happens:
1) if you're on console, 'service sshd restart' kills _ONE_ connected ssh
client and otherwise
2) if you're connected with ssh, 'service sshd restart' kills your
connection but won't start a new
one. Time to walk to the console..
The fact that all systems AFAIR had at least one incoming sshd client
process running at the time sshd was restarted might have been crucial.
This has been replicated on 5+ systems.
Bill, this definitely has to be a problem with the "daemon" initscripts
Yes. It was fixed between 7.0 and one of the various betas (the betas
don't have this problem...)
