A school wants to set up a small computer lab for its students.

Downloading and installing RPMs isn't hard, as discussed in Chapter 6, "Installing Linux Software".

The disadvantages are that NIS doesn't encrypt the username and password information sent to the clients with each login and that all users have access to the encrypted passwords stored on the NIS server.

A detailed analysis of NIS security is beyond the scope of this book, but I suggest that you restrict its use to highly secure networks or to networks where access to non-NIS networks is highly restricted.

An advantage of NIS is that users need to change their passwords on the NIS server only, instead of every system on the network.
