Pinger is a small lightweigt command line programm written with ❤️ in go. It's made for testing TCP connections between to host. Therefore you must run it on both hosts, on one site in server mode and on the other side in client mode. Then the programm on the client side tries to reach the endpoint on the server side and logs it it was successfull.

You can get the latest binary using Go:

> go get -u github.com/jamowei/pinger

or download released binary from here.

If you define a server name (or hostname) with -s r --server, its starts in client mode an tries to connect to the server endpoint on the specified port(s).

Otherwise if you define only the ports you want to test, it starts a small http server for each port.
