SUMMARY: OpenSSH - Could not load host key: /etc/sshd/ssh_host_rsa_key

From: LOEWENTHAL Simon <>

The problem was two fold:

1) The sshd_config should have been modifed to look for the keys under 
/etc/ssh instead of /etc/sshd, instead of using the -h option.  Since my 
sshd_config is on an NFS mount then this was easier than rolling the 
change out to all the clients.

2) Pam was spitting out an error message, which stopped non-root 
accounts from logging in.  When the UsePAM option in the sshd_config was 
toggled to no the users could log onto the system.

Many thanks to all those of you who replied:   Eric Lewandowski, Andrew 
Hall, Chrisopher L Bernard, Crist Clark, Mauricio Tavares, and Micheal 

Regards, Simon.
