Bug#647493: rkhunter: Please allow deactivation of reports

[Alexander Reichle-Schmehl]

Package: rkhunter
Version: 1.3.2-6
Severity: minor
Tags: patch


Hi!

In our setup we use rkhunter on several systems and monitor the results of
the daily runs via our monitoring system.  So, we'd like to disable the
report mails.

However, unsetting MAIL-ON-WARNING in /etc/rkhunter.conf wasn't enough, as
we found out, that mails are also send from the cronjob itselfe (Why, if I
may ask?  Doesn't rkhunter itself already has the mail feature?)

Unsetting REPORT_EMAIL in /etc/cron.daily/rkhunter also didn't solved the
issue for us, as the "| /usr/sbin/sendmail $REPORT_EMAIL" in the cronjob
fails.

However, with the following patch:

-        if [ -s "$OUTFILE" ]; then
+        if [ -s "$OUTFILE" -a -n "$REPORT_EMAIL" ]; then

Report mails can be disabled, while keeping the functionality.


Best regards,
  Alexander
