Program Name: rpcclient.c  
Purpose: Acts like a feeble rsh client. Executes a command on another machine.

How does it do this?  Using UDP/IP (another protocal) a Remote
proceedure has been defined which the client calls with a parameter of
command.  The returned result is a string of charaters resulting from
the execution of the client's command on the remote machine.

Why? Lets say there was a file on your friends machine that you
needed.  You could run this niffty program like: 'runc dec5ki cat
herfile.c' and waaala, it would appear on your terminal.  Nice eh!

Notes: This program will run on hercules and the Dec stations.  The C
compiler on the Dec stations seem to be a tad less forgiving with
pointers, so there will be a few warnings.  This could easily be fixed
by casting! The skeleton for this program was origionally written by
Rob Kowalchuk
