I'm trying to use dsa key pairs so that I can ssh in a cron script without
passwords. I've generated the key pair, then copied the public key to the
server. Client is Hoary, and server is Debian Sarge.
When I ssh, I get asked for a password. Is there some step I'm missing? Is
there something in the sshd_config or ssh_config that needs fixing?
Another point: since sudo is not an option in this case, does that mean I
have to activate root?
While I'm asking.. can anyone tell me if there is any advantage of either RSA
or DSA?
Below is what I actually did.
thanks... David.
david at foo:~/.ssh $ ssh-keygen -t dsa
