hi

I might be totally off the mark here, but has slapper now changed to port
1812? This'll make it really difficult to filter, if you're using this
port for RADIUS.


We saw this yesterday, directed at a previously infected slapper.a
(2002/udp backchannel) host on a a customer's network, and I sent the
captured info to CERT to see what they made of it.

I didn't know if it was the slapper communications channel, or one of the
triggered DDOSs from slapper.
