I have two machines on the same local network. One is a Mac (192.168.42.74) and one is a Dell (192.168.42.75) running Kubuntu Linux.
If I issue 'nc -l 12345' on the Mac and issue 'echo "blah" | nc 192.168.42.74 12345' from the Linux Machine, I see "blah" show up on the other end at the Mac...
But if I reverse the roles and issue 'nc -l 12345' from the Linux Machine and 'echo "blah" | nc 192.168.42.75 12345' from the Mac, I don't get anything showing up on the other side.
Does anyone know why there is this asymmetry between the machines? Not sure where to start troubleshooting this one.

Check your firewall on the Kubuntu machine. – heavyd – 2015-06-04T06:36:56.973
Works perfectly between my Kubuntu and my Mac OS, listen to @heavyd! – MariusMatutiae – 2015-06-04T08:47:17.150
