Hello Joel,

You can id the process or processes easily. To work from the command line,
look into:

man netstat
man tcpdump
man ifconfig
man ps

learn about the /proc/ filesystem. There are docs in the kernel source code
tree under the Documentation directory.

You'll know what to do, once you id the process or processes.
