UUCP Considerations

When using the Permissions file to restrict the level of access granted to remote computers, you should consider the following:

• All login IDs used by remote computers to log in for UUCP communications must appear in one and only one LOGNAME entry.

• Any site that is called having a name that does not appear in a MACHINE entry, has the following default permissions or restrictions:

  • Local send and receive requests are executed.

  • The remote computer can send files to your computer's /var/spool/uucppublic directory.

  • The commands sent by the remote computer for execution on your computer must be one of the default commands, usually rmail.
