I have a firewall that sends a ling to syslog on my Linux box every 5 mins with the number of bytes transferred in that time: Jun 2 14:52:37 192.168.146.100 NameOfFirewall: Stats filter 12: 1363 (All out) I want to srtip this number out every 5 mins so I can feed it to MRTG. Any sugestions about the best way to achieve this? Simon Simon Faulkner
