Unix networking

Unix networking involves the following subsystems:

1. The YP (yellow pages) server: Supplies authentication and user profiling information (such as password, home directory location, and login shell).
2. 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 to telco1.
