[Dshield] Many Hits on Port 26809

Do you have a network or is this a standalone box?

What software have you run today?

Check netstat see if your box is ready to receive date on UDP 26809
(netstat -an) if so use netstat -ano to get the PID and netstat -anb to
get the executable name that opened the port and track it down from

If that fails you could allow it through and packet capture it, see if
you can make sense of the payload. At least if you allow it the system
will send back a port unreachable and hopefully the remote address will
forget you.

Except that, while my IP address IS assigned dynamically, I've had this
IP address for 3 days now. Everything was quiet until earlier this
afternoon. Suddenly, I'm inundated with all these hits on port 26809.
