If all you want to do is issue commands, ssh is capable of doing that
directly, e.g., (from a shell prompt):

    $ ssh 10.2.3.4  tail /var/log/syslog

This can be automated by setting up key-based authentication and
ssh-agent, e.g., using the keychain utility.

IMHO Expect.pm and such are called for when you want to automate
interactivity with the remote system, i.e., generate output commands
based on the responses seen.
