Some syslog-ng filter examples 
# Get almost all messages according to 
# facility and priority (old syslogd concept)
filter f_all { level(debug .. emerg); };

# Filter just messages for ssh login attempts
filter f_sshlogin { program("sshd.*") and match("(Failed|Accepted)"); };

# Filter anything with "mymsg" messages
filter f_rmatch { match("mymsg"); };

Monitoring Compaq Computer Corporation Smart Array pomoci Nagiosu 
# kudzu -p | grep Array
desc: "Compaq Computer Corporation Smart Array 5i/532"


You will need hpaducli-8.60-8.0.noarch.rpm which contains HP Array Diagnostics Utility (CLI) for Linux. It can be downloaded here:

http://h20000.www2.hp.com/bizsupport/Te ... 9c1ff709dd

The output from the command line diagnostics looks like:

# /usr/sbin/hpacucli controller all show status
Smart Array 5i in Slot 0 (Embedded)
Controller Status: OK
Cache Status: OK
Battery/Capacitor Status: OK


The actual script for getting the controller status (Nagios probe):

#!/bin/sh

STATE_OK=0
STATE_WARNING=1
STATE_CRITICAL=2
STATE_UNKNOWN=3
STATE_DEPENDENT=4
/usr/bin/sudo /usr/sbin/hpacucli controller all show status > /tmp/check_raid.tmp$$

CTRLR_STATUS=""
while read line
do
CTRLR_STATUS=`echo -n $CTRLR_STATUS $line " "`
done < /tmp/check_raid.tmp$$


if [ `cat /tmp/check_raid.tmp$$ | grep "Status:" | grep "OK" | wc -l` -lt 3 ]; then
echo "CRITICAL: $CTRLR_STATUS"
rm /tmp/check_raid.tmp$$
exit $STATE_CRITICAL
fi
echo "OK: $CTRLR_STATUS"
rm /tmp/check_raid.tmp$$
exit $STATE_OK


The /usr/sbin/hpacucli requires root to run, therefore Nagios should use sudoers to run the tool:

Cmnd_Alias HPACUCLI = /usr/sbin/hpacucli
%nagios ALL = NOPASSWD: HPACUCLI


As it will not run as the interactive session we must comment out requiretty:

#Defaults    requiretty.

Denyhost: less password attacks guaranteed 
DenyHosts is a python program that automatically blocks ssh attacks by adding entries to /etc/hosts.deny. DenyHosts will also inform Linux administrators about offending hosts, attacked users and suspicious logins.

install

wget http://downloads.sourceforge.net/projec ... ror=freefr
tar xvfz DenyHosts-2.6.tar.gz
cd DenyHosts-2.6
python setup.py install
cd /usr/share/denyhosts/
cp denyhosts.cfg-dist denyhosts.cfg
cd -
cp /usr/share/denyhosts/daemon-control-dist /usr/share/denyhosts/daemon-control
cd /etc/init.d
