Yesterday I noticed the following entry in logs:

Packet log: input REJECT eth0 PROTO=17 169.254.208.158:137 
169.254.255.255:137 L=96 S=0x00 I=3072 F=0x0
000 T=128 (#9)

This occured only on our internal (10.10.x.x address) network. The packets 
were seen three times over the course of the day but lasted for only one - 
two seconds so it was impossible to get a tcpdump.

In addition the source address was either 169.254.208.158 or 
169.254.24.111. We don't use the above addresses on the network so am I
