		     Kerberos on EECS Instructional Systems
		     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


Kerberos is set of programs that allows users to login to remote computers
over the network without exposing their passwords to illicit network packet-
sniffing programs.  It encrypts the password before it is sent over the net.
It is mostly used to login securely between UNIX computers.  The EECS 
department runs servers that support Kerberos 4 and Kerberos 5.  

The standard (unencrypted) "telnet", "rlogin" "rsh" and "rcp" programs are 
not allowed for logging into any Instructional computer.  The EECS 
Instructional UNIX computers and many other UNIX computers in the department 
support Kerberos, but most people are using SSH now instead.
