The checkpc (check printcap file) is one of the most
useful utilities in the LPRng package.
It will read all the configuration files, printcap files and tests
whether devices are set up correctly. Optionally, it will also set the
permissions for spool directories and device files. Additionally, it
will truncate the accounting and log files to a maximum size. Another
use for checkpc is to remove old entries from queue
directories.
For a new installation, you will want to run
checkpc -f -V
-f flag instructs the
program to correct file permissions. If you don't run this as
root, you'll receive a warning about that fact and any
chown(2) calls will (most likely) fail.
The program reports everything it changes. Since it isn't too clever about some things (visit the man page), you should keep an eye on the output, and run it again if needed. If it keeps failing, change the permissions yourself.
Later, you will want to use checkpc for the daily
maintenance of your system. I have this line in user lp's
crontab:
32 5 * * * checkpc -t 10K -A3 -r >/dev/null 2>&1
-t 10K).
Actually, it will keep the last 10K from the file, starting on a
complete line.-A3 -r)./dev/null, because checkpc
is a little noisy to my taste. (But too noisy is better than too
silent :)
You can use checkpc -V -P
to examine printcaps and tell you what
they contain.
This is identical to the lpc server all operation,
but with a higher level of verbosity.
