Subject: Really ODD 12 byte UDP attempts

Hey All!

Since there doesn't seem to be much going on I thought I'd ask about
this.  I've searched and either I suck (must likely) or it's something
else.  Here's a snippet of what I see:

Aug 28 06:57:01 kernel: New,invalid SRC=64.94.45.26 DST=24.116.255.102
LEN=32 PROTO=UDP SPT=11050 DPT=33440 LEN=12

This modified netfilter log line is just one of many I see.  The only
thing that all the attempts have in common is that the LEN=12 and that
the DPT=344**.  They usually come in bursts of 6 or 8.

The reason I'm posting this now is because there have been a BOATLOAD
of these in August...but not much in other months..as follows:

April:	317
May:	176
June:	352
July:	292
August:	1207

To save time and space I have 2 files on a site:

To view all source IP's:

To view raw(edited) log:

I looked up the ports on isc.sans.org but found nothing.  Anything out
there going on that I should know about?  Thanks all!

James
