I'm not seeing any traffic on port 9202 using:
tcpdump -i eth0 port 9202
I tried specifying a terminal, but when nothing showed up, I tried
leaving that out, to "sniff" for any port 9202 traffic. I get
nothing after a few minutes of listening. I still have a 5-6% CPU
usage on TONS of lbussd processes though.
UPDATE: I just had a couple packets show up, but nothing that looks
abnormal. I can send the results if you like, but it's just 3 packets.
On my second server (not as slow, but still not "normal"), I have
about half a dozen lbussd processes, all using between 15-25% CPU.
The servers are running K12LTSP 6.0, and are configured similarly.
Perhaps I've configured something poorly...
