Your question is still not clear. Do you want to know about existing remote command execution facilities in unix or are you interested in writing one of your own?
Some of the existing commands are: remsh(HP-UX), rsh(Solaris,Linux) and ssh(download from openssh.org and install seperately).
If you have to write one yourself, you are going to have to play around with sockets and the exec* family of commands a lot. I suggest that you get copies of "Advanced Programming in the Unix Environment" and "Unix Network Programming - Volume 1" by Stevens and get reading.

UUID(3) Libuuid API UUID(3)
NAME
uuid - DCE compatible Universally Unique Identifier library
SYNOPSIS
#include <uuid/uuid.h>
DESCRIPTION
The UUID library is used to generate unique identifiers for objects that may be accessible beyond the local system. This library generates
UUIDs compatible with those created by the Open Software Foundation (OSF) Distributed Computing Environment (DCE) utility uuidgen.
The UUIDs generated by this library can be reasonably expected to be unique within a system, and unique across all systems. They could be
used, for instance, to generate unique HTTP cookies across multiple web servers without communication between the servers, and without fear
of a name clash.

OSF DCE 1.1
AUTHOR

AVAILABILITY
libuuid is part of the util-linux package since version 2.15.1 and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
