Contain the BNU program log files.
The /var/spool/uucp/.Log directories contain Basic Networking Utilities (BNU) program log files. The BNU program normally places status information about each transaction in the appropriate log file each time you use the networking utilities facility.
All transactions of the uucico and uuxqt daemons as well as the uux and uucp commands are logged in files named for the remote system concerned. Each file is stored in a subdirectory of the /var/spool/uucp/.Log directory, named for the daemon or command involved. Each subdirectory contains a separate file for each remote system contacted. Thus, the log files are named according to one of the following formats:
/var/spool/uucp/.Log/DaemonName/SystemName
/var/spool/uucp/.Log/CommandName/SystemName
All activities of the uucp command are logged in the SystemName file in the /var/spool/uucp/.Log/uucp directory. All activities of the uux command are logged in the SystemName file in the /var/spool/uucp/.Log/uux directory.
The uucp and uuto commands call the uucico daemon. The uucico daemon activities for a particular remote system are logged in the SystemName file in the /var/spool/uucp/.Log/uucico directory on the local system.
The uux command calls the uuxqt daemon. The uuxqt daemon activities for a particular remote system are logged in the SystemName file in the /var/spool/uucp/.Log/uuxqt directory on the local system.
When more than one BNU process is running, however, the system cannot access the standard log file, so it places the status information in a file with a .Log prefix. The file covers that single transaction.
The BNU program can automatically append the temporary log files to a primary log file. This is called compacting the log files and is handled by the uudemon.cleanu command, a shell procedure. The procedure combines the log files of the activities of the uucico and uuxqt daemons on a particular system and stores the files in the /var/spool/uucp/.Old directory.
The default is for the uudemon.cleanu command to save log files that are two days old. This default can be changed by modifying the appropriate line in the shell procedure. If storage space is a problem on a particular system, reduce the number of days that the files are kept in their individual log files.
The uulog command can be used to view the BNU program log files.
These directories are part of the Basic Networking Utilities Program (BNU) in BOS Extensions 1.
