Systems affected: Fedora 37 – 40

Update

It appears at times updates will reset the changes made below. So – I created a new solution

Create a file named /etc/cron.daily/00LogwatchDetail and insert the following

#!/bin/bash

sed -i "s/my\s*\$Detail\s*=\s*\$ENV{'LOGWATCH_DETAIL_LEVEL'}\s*||\s*0/my \$Detail = \$ENV{'LOGWATCH_DETAIL_LEVEL'} || 1/" /usr/share/logwatch/scripts/services/fail2ban
 

make sure you
chmod 700 /etc/cron.daily/00LogwatchDetail 

The above will check the /usr/share/logwatch/scripts/services/fail2ban to make sure it is set correctly every day

Install fail2ban as needed. Information is being logged correctly to /var/log/fail2ban. Updates executed by fail2ban are not reported in logwatch.

Correction:

edit /usr/share/logwatch/scripts/services/fail2ban

Find the line:

my $Detail = $ENV{'LOGWATCH_DETAIL_LEVEL'} || 0;

change it to be:

my $Detail = $ENV{'LOGWATCH_DETAIL_LEVEL'} || 1;

Additional Notes:

Testing logwatch –

Get a report just on the screen just about the service fail2ban

/usr/sbin/logwatch --detail 1 --service fail2ban
