🦋 (Relatively) Close to the metal
Neat-o, I found a new tool for testing stuff out! It is called netcat and it is essentially what I've always wished telnet would be. You can basically open up a socket and listen as the server or attach as a client, and see all the traffic from the other party, and type in the traffic from your side. Be sure to read the (brief) man page as the tutorial pages I've found on the web this morning all omit important information and leave you scratching your head as to what is going wrong. The two things (at first glance) that nc has over telnet: primary point is that you can listen on a port, and thus emulate a server; telnet does not do this at all. Secondary advantage, the whole thing is much cleaner and simpler, and easier to run as a batch job; you don't have to learn escape characters or anything like that. Drawback is that error reporting is pretty minimal; but I can live with that.
