RE: Traffic on UDP 1815

["Sahr, Kenneth" <ksahr () fiwc navy mil>]

Actually, I was able to determine it's source late last night..It turns out that P2P software Kazaa was causing the 
connections to come back, I can't imagine what it uses UDP 1815 for, however, as I blocked all incoming queries to that 
port and was still able to search and download files..while doing so I saw many packets attempt to come in on the 
suspect port, but all were dropped by my firewall.  Like I said, not sure why this traffic was occuring, but at least I 
know what was causing it..  Thanks everyone for your answers.

It appears MMPFT is the acronym for "Multimedia Portables For Teachers".
Not a heavily used service I would think.  You say you these packets are
coming to your home machine.  Can we assume this is a dynamic IP connection
and perhaps the packets are intended for the user assigned that IP from an
earlier time? Unfortunately, UDP provides few clues and it is often hard to
draw any conclusion unless full payload captures are available.

Hi all, longtime lurker, first time poster to this forum.  I've been seeing
a lot of traffic on my home Win2K pro machine lately from random IP's/high
numbered source ports to UDP 1815, which is registered as "MMPFT"..this is
all the information I can gather on it though..anybody have any insight into
what this might be? I'm hoping someone's seen it before.. I also checked,
there is no initial packets sent out from my machine to any of these source
IP's..so I don't suspect any kind of callback, and I don't really expect any
sort of intrusion at all..just curious as to what this service is..

Thanks in advance for any replies
