'ping' is always a good tool to test connections between hosts.

$ ping -c 4 pc1
$ ping -c 4 pc2

Try it from both machines and if everythings is working you should see a 
reply message from the ping commands.

NB! if the machines are connected directly (without a router etc) you'll 
need a cross-over cable to get your setup to work.
