Hello there,

I have noticed something kinda interesting about the Linux boxen on my
network.

Basically it seems that they won't talk UDP to each other.
When I try: nmap -v -v -sU <Linux_Hostname>, it just times out and
increases the senddelay.

I have a couple of BSD boxes on the network too. When I do a UDP port
scan of them, they respond. However, when I port scan a Linux box, from
either a BSD machine or another Linux machine, it won't respond.

Does anybody know what is going on here?

Regards,

Chris Fletcher.
