The method I use is to check the hobbit logs, and if everything looks
ok, and says it is running normally, then:
tcpdump -tn -A -s0 -i eth0 port 1984

on the client machine. This will show all network traffic on eth0 (use
the correct device, but usually eth0 on linux), to the hobbit server
(port 1984). You should be looking for the start of lines where you will
see the hostname being reported, and where the reports are being sent to
(maybe wrong IP address of your hobbit server)...

Hope that helps...

PS, it would be nice for the BB server to return a "OK" after receiving
a report, so the client could log that the message was successfully
delivered or not...

Adam
