    Greetings,
    
    Destination port 6700 and 6688 are common napster ports.  Any possible way
    you were running a napster client?

    While remotly connected to my home machine, I noticed alot of lag.  I
    executed a 'netstat -a' which showed me nothing out of the ordinary.  But
    when I started tcpdump I saw traffic which I could not account for.
    
    Here is a snip of my tcpdump log..
    Key: x.x.x.x = my ip
    
    16:26:14.957566 24.109.6.174.6700 > x.x.x.x.63781: tcp 0 (DF)

    16:26:15.449510 x.x.x.x.63783 > 172.150.125.247.6688: tcp 688 (DF)
    16:26:15.479993 172.174.174.84.6700 > x.x.x.x.63780: tcp 0 (DF)
    16:26:15.485314 x.x.x.x.63780 > 172.174.174.84.6700: tcp 1360 (DF)
    
    I was unable to capture any of the packets, and a nmap of my machine showed
    no unusual ports open.  Anyone have any ideas on what this could have been?
    
    Thanks in advance,
