All, Apologies if this is a simple error but it's been confusing me for a few weeks and I have no idea how to fix it. I've set a cron job to run 3 times an hour (as root) and logcheck's picking up on this (but no others). The output in the email is this:- Jan 8 20:21:01 homer /USR/SBIN/CRON[8637]: (root) CMD (/usr/bin/python /root/denyhosts/denyhosts.py -c /root/denyhosts/denyhosts.cfg) Jan 8 20:41:01 homer /USR/SBIN/CRON[2949]: (root) CMD (/usr/bin/python /root/denyhosts/denyhosts.py -c /root/denyhosts/denyhosts.cfg) Jan 8 21:01:01 homer /USR/SBIN/CRON[12711]: (root) CMD (/usr/bin/python /root/denyhosts/denyhosts.py -c /root/denyhosts/denyhosts.cfg) I've added the following to /etc/logcheck/ignore.d.server/cron (I assume this is the correct file):- ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ \USR\SBIN\CRON\[[0-9]+\]: \([_[:alnum:]-]+\) CMD \(/usr/bin/python /root/denyhosts/denyhosts.py -c /root/denyhosts/denyhosts. cfg\)$ All the testing I've carried out shows that this is correct. I am running Debian Stable and the version of logcheck from aptitude is 1.2.39. Can anyone point me in the correct direction? Thanks, Andrew -- Andrew Berry andrew@aberry.co.uk http://www.aberry.co.uk
