today my daily security check output shows this:

kernel log messages:
> \^H\M^@@@\^P\^B\^B\^B\^A\^H\^H\^D\^P\^B\^H@Copyright (c) 1992-2000 The
FreeBSD Project.

> ipfw: 1900 Deny UDP 64.13.99.12:137 255.255.255.255:137 in via fxp0

Anybody know what could produce that first line ? should I be concerned
about this ?

please CC me as I am not currently subscribed to the list

Thanks
