You're heading way off base very fast, here...
The first thing to do is to find out whether there actually is any
network traffic going past. Then you need to find out whether it's
network traffic that you want to be going through.
Simple first test: if you bring down the main network interface on
the machine, does the flickering stop?
# ifdown eth0
(Use ifup eth0 to bring it back up)
If so, then it's probably not a hardware fault, and something
really is sending network packets. Also try:
# watch -n 1 ifconfig
and watch the RX bytes and TX bytes counters.
To investigate what might be doing this communication, netstat may
help:
# netstat -ap --inet --inet6
Look at the tcp and tcp6 sockets that are "ESTABLISHED", and see
what connections you've got. The last column will give you the pid of
the process, in each case, which you can then look up in "ps axfww".
If you still can't see what might be causing the communications
you're worried about, then we can get all medieval on it with tcpdump
and/or wireshark, but the above should be a good start.
