This is a Network port tester. On one endpoint the program runs as a server and in the other endpoint the program runs as a client.
This program is usefull where you need to check if a firewall is blocking some ports.
Just run:
./QtNetworkPortPing -s {port number}
in order to start listening on port {port number}
On the other endpoint:
./QtNetworkPortPing -c {host}:{port number}
