LURKER-PRUNE(1)		    General Commands Manual	       LURKER-PRUNE(1)

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	acces-
       sible  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	 obso-
		 lete  due  to new mail	or config changes will be deleted ear-
		 lier.	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	gener-
		 ated 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.
