[Bio-Linux] Firewall logs and backup drives (maximal mount count reached errors)

[Dan Swan]

Dear all,

It has been pointed out that currently there is no /var/log/firewall.log 
for firewall alerts as there was in Bio-Linux 2.X.  These messages are 
currently being logged but not in a centralised location.

To remedy this please add the following line to /etc/syslog.conf at the 
top of the file:

kern.=debug                     -/var/log/firewall.log

then restart syslogd with:

sudo pkill -HUP syslogd

This is now fixed on the latest image.

Also if you are seeing messages like this:

Jan 26 04:02:01 yeastimp kernel: EXT3-fs warning: maximal mount count
reached, running e2fsck is recommended

in /var/log/messages then it's because the backup drive /dev/hdb1 has 
been mounted by the backup script enough times to trigger a warning 
limit.  It is not a major problem.

In order to comply with the suggestion you can run the following:

sudo umount /backups
sudo /sbin/e2fsck /dev/hdb1

You could add these lines to a file called check.sh in /etc/cron.monthly 
to ensure a monthly check takes place.

#!/bin/sh

umount /backups
/sbin/e2fsck /dev/hdb1

regards,

Dan
