    Oh I get it, this nc is for LOCAL network activity, huh?

    When I try to do it via hostname or outward Ip address it fails returning:

    This is nc from the netcat-openbsd package. An alternative nc is available
    in the netcat-traditional package.
    usage: nc [-46DdhklnrStUuvzC] [-i interval] [-P proxy_username] [-p source_port]
    	  [-s source_ip_address] [-T ToS] [-w timeout] [-X proxy_protocol]
    	  [-x proxy_address[:port]] [hostname] [port[s]]

    Hey Allen,

    If I have a server that is set up in pass-through (machine 1; not used in loop) is there a way to make this nc business work for me using machine 2 and machine 3 that are not in passthrough?
    (*passthrough is at&t’s nomenclature for demilitarized I think).

    I’ve already port forwarded a port to designate that machine 2 will host but still I cannot get machine 3 to connect…..arrrrggghhhh!!!! (now I can’t even get me to talk to me)

    thank you.

    hostname -I
    finds my ip address. Much simpler than the method shown here.

      Well, yeah.

      On the other hand, this article is a decent introduction to awk, which is a command line Swiss army knife.

      On that basis, I give it high marks, since general awk skills are a thousand times more useful than a few simple, cookbook commands.
