Just checked back again - sorry about the delay. Not that I know of - the router address is specified in the DNS tab in the network settings utility, so I think it's using RoadRunner supplied DNSs.

SYN from from where? to where? what port(s)?



This is the event log:


Description Count Last Occurence Target Source IP Fragmented Packet 4 FRI JAN 19 14:23:49 2007 me.athome.on.XP:26219 my.schools.name.server.Ithink:20375 LAN-side SYN Flood 1 FRI JAN 19 15:26:29 2007 some.atl.addr.31:80 me.athome.on.XP:1667 SYN Flood 1 FRI JAN 19 15:26:29 2007 me.athome.on.XP:1666 some.atl.addr.31:80 LAN-side SYN Flood 1 FRI JAN 19 17:13:27 2007 different.schools.server.addr:80 me.athome.on.Debian:3744 SYN Flood 1 FRI JAN 19 17:13:27 2007 me.athome.on.Debian:3745 different.schools.server.addr:80 LAN-side SYN Flood 6 FRI JAN 19 17:13:42 2007 different.schools.server.addr:80 me.athome.on.Debian:3753

etc.

I had the XP and Debian boxes up originally, then when I noticed this going on, took the XP off the network and it jumped to the Debian box.


Today, its just 124 IP Fragmented Packets from my school's server to my XP box.


Thanks -

Hello, all,

I'm new here <waves> and just came across something fairly scary. My home router shows something called an IP Fragmented Packet *from my school's DNS server*, then there's a series of LAN-side SYN Flood, then just plain SYN Flood, events to and from my [innocent, I swear!] router's IP to some address in Atlanta, back from Atlanta, then to a rival school's IP address here.

My systems are XP and Debian 2.6 - when I shut down the XP, it jumped to the Debian. Can anyone clue me into wth's going on?

Many thanks -

MG
