can't restart sshd after updgrade

Hi, Well as the subject says after installing openssh.rpm to SuSE 7.1 via # su -c ' rpm -Uhv openssh.rpm' I issued su to root and echo "rcsshd restart" |at now +2min and I logout from the machine. The command runs and sshd complains port 22 address has already binded /etc/ssh/primes not found using old prime and I still have the previous sshd running :-( Where am I doing the mistake ? Note I can not log in as root and ssh is the only access to the machine (meaning I do not have a terminal connected) -- Togan Muftuoglu
