Logs access attempts by unknown remote systems.
The /usr/sbin/uucp/remote.unknown file is a shell script. It is executed by the Basic Networking Utilities (BNU) program when a remote computer that is not listed in the local /etc/uucp/Permissions file attempts to communicate with that local system. The BNU program does not permit the unknown remote system to connect with the local system. Instead, the remote.unknown shell procedure appends an entry to the /var/spool/uucp/.Admin/Foreign file.
Modify the remote.unknown file to fit the needs of your site. For example, to allow unknown systems to contact your system, remove the execute permissions for the remote.unknown file. You can also modify the shell script to send mail to the BNU administrator or to recognize certain systems and reject others.
