    Iīve noticed that since 01/24 00:14 GMT -0200, til today, different IPīs
    started to scan my whole network for UDP port 135.
    
    They send one packet each 30 seconds, one for each IP of my whole range.
    
    The source IPīs are different from any IP sending the slammer worm for me,
    so it doesnīt seem to have any relation.
    
    Here are some of them:
    - 208.62.233.151
    - 67.34.191.69
    - 65.217.17.36, 44, and 45
    
    Iīm used to receive tons of UDP 137, on random IPīs, but never to my whole
    IP range.
    
    Is it some other simple probe directed specifically to me, and iīm
    overreacting, or maybe something else? UDP 135 is used by MS Exchange
    (portmapper)...
    
    Thanks
