openssh unix dev - Sep 2000 - RHL OpenSSH upgrade: _new_ sshd is not started

Hello all,

A few days ago I noticed that the following seems to happen when upgradign
OpenSSH on Linux-based (/etc/rc.d/init.d/sshd) based systems:

- sshd is restarted with 'sshd restart'; however sshd serving in port 22
is not replaced.

- you have to kill the old one (netstat -ltp | grep :ssh ; kill
...) first, then restart sshd.

- This might happen only when performing the upgrade while connected on
the system w/ ssh; not sure.

However, I'm not sure which would be the best way to get around this.

Are you sure - it works for me:

Any sshd's that are serving the port, if you kill them, will disconnect
someone. Let them keep running and just restart the parent process.

Me, when I work on the ssh configuration of a remote machine, log in with
telnet; and conversely, when I'm working on the srp config, I log in with
ssh.
(Telnet is set up to require srp.)
