Ubuntu Manpage: lurker-prune — prunes the web-server cache

NAME

       lurker-prune — prunes the web-server cache

SYNOPSIS

       lurker-prune [-c <config-file>]  [-f <frontend>]  [-m <days>]  [-a <days>]  [-p -v]

DESCRIPTION

       lurker-prune  prunes  obsolete  or  stale files from the web-server accessible cache. This
       command must be run at regular intervals from eg. a cronjob. If it is not  run,  then  the
       lurker  web interface will appear to not be receiving new mail or have contradictory links
       between pages. A good interval is every 15 minutes and should not exceed one hour.

       Be aware that it is possible for an attacker to use  up  a  large  amount  of  disk  space
       through  lurker. An attacker could request many distinct lurker web pages each of which is
       cached, thus using disk space. Please setup a quota for the lurker user, read  your  logs,
       and follow whatever site-specific policies you have for denial of service.

       A  good  script to run in parallel with normal lurker-prune use is one similar to: if test
       `du -s /var/www/lurker | cut -f1` -gt 32768; then lurker-prune  -p;  fi  This  might  help
       guard against a potential denial-of-service attack.

OPTIONS

-c config-file
Use this config file for lurker settings.

-f frontend
The directory of the lurker frontend cache to clean. You can selectively purge
cache with this option. By default, lurker-prune will clean all frontends
specified in the config file.

-m days Keep cached files for at most this many days. Any cached file regardless of last
access will be deleted after the specified number of days (defaults to 7). Files
which are obsolete due to new mail, config changes, or no accesses will be
deleted earlier. Deleted files will be automagically regenerated if needed.

-a days Kill cache files not accessed for this many days. Any cached file which has not
been read from for the specified number of days (defaults to 1) will be deleted.
Files which are obsolete due to new mail or config changes will be deleted
earlier. Deleted files will be automagically regenerated if needed.

-p Purge mode. Delete all cache files even if they do not appear to be expired.
This will only deletes files that are generated by lurker, and is thus
preferable to rm */*.

-v Verbose operation. Indicate which files are being deleted and the reasoning
behind lurker's decisions. This can help in tracking down why some files are
deleted and not others.
