Setting Up UUCP Security

The default /etc/uucp/Permissions file provides the maximum amount of security for your UUCP links. The default Permissions file contains no entries.

You can set additional parameters for each machine to define:

• Ways it can receive files from your machine

• Directories for which it has read and write permission

• Commands it can use for remote execution

A typical Permissions entry is:

MACHINE=datsun LOGNAME=Udatsun VALIDATE=datsun 
COMMANDS=rmail REQUEST=yes SENDFILES=yes

This entry allows files to be sent and received (to and from the "normal" UUCP directories, not from anywhere in the system) and causes the UUCP user name to be validated at login time.
