I have 2 questions:
1) how can I restrict users from being able to su to root? Currently, I'm able to su to root and it does not ask for a password while connecting through ssh.
2) How do you setup a banner message for users as they log into the system via ssh. I thought it was:
BannerMessageFile /etc/issue.net
however, I cannot seem to get this to work.
Thanks,
Tim Doyle
