See the man page for ssh. You can, if you set up ssh correctly, run a ssh to hostname with optional command.

Quote:
DESCRIPTION

ssh (SSH client) is a program for logging into a remote machine and for
executing commands on a remote machine. It is intended to replace rlogin
and rsh, and provide secure encrypted communications between two
untrusted hosts over an insecure network. X11 connections and arbitrary
TCP/IP ports can also be forwarded over the secure channel.

ssh connects and logs into the specified hostname (with optional user
name). The user must prove his/her identity to the remote machine using
one of several methods depending on the protocol version used.

If command is specified, command is executed on the remote host instead
of a login shell.
