WireShark is great for monitoring all kinds of traffic on a network.

If you'd like to only see local traffic, you can use capture filters.

For example:

net 192.168.0.0/24

Depending on the level of detail you are interested choose from this list.

  1. Wireshark -- for detailed packet inspection
  2. Sysinternals TCPView -- for basic connection activity on a Windows machine
  3. iptables for basic connection activity on a unix machine
