Without something **like** ssh you cannot issue commands on remote machines.
I am aware of 3 generic ways of having some level of access to a remote machine:
ftp and its variants---file transfer, no commanding of the remote
remote cli login tools such as telnet, ssh, and others
remote gui login tools such as vnc
In all cases, you must first establish a connection before having access to to whatever commands are available.
Why do you not want to use ssh? tell us more about the application
