Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

CLIENT/SERVER MODEL
     It is quite simple to build a very basic client/server model using nc.  On one console, start nc listening on a specific port for a connection.  For example:

           $ nc -l 1234

     nc is now listening on port 1234 for a connection.  On a second console (or a second machine), connect to the machine and port being listened on:

           $ nc 127.0.0.1 1234

     There should now be a connection between the ports.  Anything typed at the second console will be concatenated to the first, and vice-versa.  After the connection has been set up, nc does not really care which side is being used as a ‘server’ and which

Creating Keys

This is a brief guide to creating a public/private key pair that can be used for OpenSSL. While the "easy" version will work, I find it convenient to generate a single PEM bundle and then export the private/public key from that as needed. This document also covers how to add and remove a password from your private key and how to make sure that keychain will automatically unlock it when you sign in.

Just make it work
