[ale] Linksysmon report extract?

Hey all,

	I haven't built a transparent poxy server yet, still using my Linksys BEFSX41 
router. I'm using Linksysmon-1.1.2 to grab the router logs (through 
snmptrapd). The logs are written as a flat file to /var/log/linksys.log

	Have any of you come across a report tool that analyzes Linksys logs? I'l 
like to start putting that data into a more understandable format. 

The format looks like this:
Parse error: >                s: Print only last symbolic element of oid.<
Parse error: >                S: Print MIB module-id plus last element.<
Parse error: >                t: Print timeticks unparsed as numeric 
integers.<
Parse error: >                v: Print Print values only (not OID = value).<
Parse error: >                T: Print human-readable text along with hex 
strings.<

It looks like I would drop records starting with "Parse error", and keep 
records starting with my router's inside IP address - 192.168.1.1. It also 
looks like I can get the date, time, direction (in or out), IP address from 
and to, protocol (udp or tcp) and port. Where DNS lookup is enabled, I get 
the name.
