uucp login ID
When BNU is installed, all of the configuration files, daemons, and many of the commands and shell procedures are owned by the uucp login ID.
The uucp login ID has a user ID (UID) of 5 and a group ID (GID) of 5. The cron daemon reads the /var/spool/cron/crontabs/uucp file to schedule automatic jobs for BNU.
Usually, logging in as user uucp is not allowed. To change files that are owned by the uucp login ID, log in with root authority.
Attention: Allowing remote systems to log in to the local
system with the uucp login ID seriously jeopardizes the security
of the local system. Remote systems logged in with the uucp ID can
display and possibly modify the local Systems and Permissions files
depending on the other permissions specified in the LOGNAME entry.
It is strongly recommended that you create other BNU login IDs for
remote systems and reserve the uucp login ID for the person responsible
for administering BNU on the local system. For the best security,
each remote system that contacts the local system must have a unique
login ID with a unique UID number.
The operating system provides a default nuucp login ID for transferring files.
