On my workstation I noticed that my network utilization is high and constant even though I don't have any downloads currently going. I fire up iftop and see the following entry at the top:
255.255.255.255:bootps => * :bootpc 0b 0b 0b <= 133Kb 162Kb 163Kb
The actual download speeds vary between 70Kb to 170Kb or more. bootps is port 67, bootpc is port 68.
I have no idea what this might be. Has anyone seen this before? Is some system on this LAN going haywire?
