A tool that I use a great deal is lsof, as in "lsof -i" which shows me 
every port in use, the PIDs/user driving them, and the remote connection 
IP and port, e.g. (my Pi hostname is "allstar"):

COMMAND     PID            USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
...
asterisk   3764            root    7u  IPv4  30034      0t0  TCP 
localhost.localdomain:5038 (LISTEN)
asterisk   3764            root   17u  IPv4  30038      0t0  UDP *:iax

sshd      11678            root    3u  IPv4  90101      0t0  TCP 
allstar:rsh-spx->192.168.1.106:60316 (ESTABLISHED)
...

Even more detail is available when run as root. The online manual page 
is informative, as usual.
