How is your ssh directory !!!?

#ls -al /etc/ssh

Do they exists in the places where your sshd_config is telling they should be?

Check

# grep HostKey /opt/ssh/etc/sshd_config
# HostKey for protocol version 1
#HostKey /opt/ssh/etc/ssh_host_key
# HostKeys for protocol version 2
#HostKey /opt/ssh/etc/ssh_host_rsa_key
#HostKey /opt/ssh/etc/ssh_host_dsa_key

If the HostKey directives are commented
they are expected in these default place.

Also check if they have restricted perms like

# ll /opt/ssh/etc/ssh_host_{rsa,dsa}_key
-rw------- 1 root sys 672 Oct 1 2002 /opt/ssh/etc/ssh_host_dsa_key
-rw------- 1 root sys 883 Oct 1 2002 /opt/ssh/etc/ssh_host_rsa_key

If you cannot find any host keys then you must generate them as root.

e.g.

# for c in rsa dsa;do ssh-keygen -t $c -b 1024 -N "" -f /etc/opt/ssh/ssh_host_${c}_key; done

Then try starting sshd again

# /sbin/init.d/secsh start

I rebooted and that seemed to have fixed the issue although I'm not sure why.

Thanks!
