Thank you so much for responding ... I'll try to work on it this weekend to convert from bash to perl. And good call with the log rotating. :)
If anyone is interested, here is my bash script:
#!/bin/bash
string="connection_input: conn=11"
tail -n 0 -F /var/log/ldap.log | \
while read LINE
do
echo "$LINE" | grep -q $string
if [ $? = 0 ]
then
echo -e "$string found on $HOSTNAME" | mail -s "LDAP authentication on
+ $(hostname)" teamsupport@yourdomain.com
fi
done
But I have to start it with a no hangup script
#!/bin/bash
nohup ./ldap_log_reader.sh 0<&- &>/dev/null &
