By “client”
we mean the machine you will be connecting from. Simply make sure
that the openssh-clients
package is
installed.
Type ssh username@remote_machine to connect
to the remote_machine
system with the
username
account. You will be asked for your
password on the remote system. Enter it and you'll be granted
access as if you were sitting at that remote system's
console.
Whether you connect to one or many machines (common scenario for system administrators), the password prompt step can be bypassed by using SSH keys. Use the ssh-keygen command to generate your SSH key, and then the ssh-copy-id username@remote_machine command to copy your key over to the remote machines. When you issue the ssh-copy-id command you will be asked to enter your password on the remote system, but only once per system. Now you can SSH directly into the remote machines without being asked for your password.
