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