Not exactly clear what you mean by a list, but check the below:

- ifconfig will give a list of interfaces and their status

- netstat -i will give a list of the interfaces and how much traffic 
has gone through them

- netstat by itself will give a list of current connections

- tcpdump -i (interface) (i.e. tcpdump -i en0) will give a live stream 
of packets passing through the interface - hit control-C to stop

Use the man command with any of these to get more info.  Hope this 
helps!
