View source for Generating new ssh server keys


Reference: [http://www.softec.lu/site/DevelopersCorner/HowToRegenerateNewSsh How to regenerate new ssh server keys - XWiki]

If you clone an existing server setup to create a new server, you'll probably want to generate a new set of keys for the new ssh server.

For SSH1 protocol, you need an rsa1 key:
 ssh-keygen -q -f /etc/ssh/ssh_host_key -N '' -t rsa1
For SSH2 protocol, you need two keys, one rsa key and one dsa key:
 ssh-keygen -f /etc/ssh/ssh_host_rsa_key -N '' -t rsa
 ssh-keygen -f /etc/ssh/ssh_host_dsa_key -N '' -t dsa
