You can install and run a ssh binary, which you can use to log into
another system on which sshd is running.
If you want to log in to the remote system without typing in your
password, you'll have to generate a private key in your home directory
using ssh-keygen, then put your public key into
$HOME/.ssh/authorized_keys.
You can also start up sshd yourself as non-root, supplying the -p
option so it binds to a non-privileged port (>1024), and then connect
from another system with ssh -p. This will only allow connections to
your own account, and sshd will, as a rule, not be restarted when your
machine reboots.
You will have to decide wether this is useful for you or not.
