Package: protocon
Protocon is a socket-centric framework for rapidly prototyping
connections through simple send and receive commands. Think socat with
pretty hex output and more send / receive automation control.InstallingProtocon requires Python 3.4+ and can be installed via pip using the
commandpython3-mpip install protocon.Example UsageManual ModeStarting Protocon requires atarget_urlargument which describes the
type of socket to open and the endpoint to connect to. Protocon will
then switch to an interactive console where various commands are
available to send and receive data.user@localhost:~$ ./protocon tcp://github.com:22
