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 what-
       ever 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 num-
		 ber 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.
