Unix networking involves the following subsystems:
- The YP (yellow pages)
server: Supplies authentication and user profiling information
(such as password, home directory location, and login shell).
- The NFS file server
exports the user's home directory to the client workstation where he
is logged on to.
Unix networking is used mostly for the conference
(athos/aramis/portos) and physics computers (torr). It is also
necessary for modem logins
