Can anyone help me identify the following?

My Mandrake 7.0 (2.2.14) machine is equipped with a eepro100 adapter. I am
seeing a continuous series of UDP packets being bradcast from this machine.
Packets are being sent from my machine at 192.168.1.1:1069 (logan) to
255.255.255.255:5456. 

TCPDUMP shows the packets as:

11:35:42.119078 logan.1069 > 255.255.255.255.5456: udp 256
11:35:47.373467 logan.1069 > 255.255.255.255.5456: udp 256

I captured the payload using Ethereal:
