This is intended as an example for Computer Networks 2 class at Poznań University of Technology. Mostly usable by my students. Goecho lousy implements Echo protocol over TCP/UDP described in RFC862.

For a daytime, check here

go get -u github.com/tdi/goecho

goecho [-h] [-H HOSTNAME] [-p PORT] [-u]

By default godaytime listens on port localhost:2222, -u makes it listen on UDP port.

➜  nc localhost 2222
hello there
hello there
