openssh-2.5.2p2-1.7 has a new init script
this fails to start a the ssh daemon if another sshd process is running
(which is the case if some are logged in via ssh)
login via ssh
after that the master ssh daemon does not run.
reason: it is started with "daemon" from "init.d/functions" which in
turn uses "pidofproc" to see if there is already a "sshd" running -- and
finds the "sshd" process from my login session.
openssh-2.5.2p2-1.7.2 (updated errata) does not use daemon, and should have this fixed.
If not, please reopen.
