Compaction of Log Files
The files SYSLOG and LOGFILE that contain logging information are compacted
daily (using the pack command from the shell script uudemon.day ) and should be
kept for 1 week before being overwritten.
Polling Other Systems
Systems that are passive members of the network must be polled by other
systems in order for their files to be sent. This can be arranged by using the
uusub (1) command as follows:
uusub -cmhtsd
which will call mhtsd when it is invoked.
Problems
The following sections list the most frequent problems that appear on systems
that make heavy use of uucp (1).
Out of Space
The file system used to spool incoming or outgoing jobs can run out of space
and prevent jobs from being spawned or received from remote systems. The
inability to receive jobs is the worse of the two conditions. When file space
does become available, the system will be flooded with the backlog of traffic.
Bad ACU and Modems
The ACU and incoming modems occasionally cause problems that make it
difficult to contact other systems or to receive files. These problems are usually
readily identifiable since LOGFILE entries will usually point to the bad line. If
a bad line is suspected, it is useful to use the cu (1) command to try calling
another system using the suspected line.
Administrative Problems
Some uucp networks have so many members that it is difficult to keep track of
changing passwords, changing phone numbers, or changing logins on remote
systems. This can be a very costly problem since ACU’s will be tied up calling
a system that cannot be reached.
I.5 Debugging
In order to verify that a system on the network can be contacted, the uucico
daemon can be invoked from a user’s terminal directly. For example, to verify
that mhtsd can be contacted, a job would be queued for that system as follows:
