An explanation of TCP, UDP, and how to use netcat on Ubuntu to send data over the network.
NOTE: At 2:14 there is incorrect netcat syntax! Don't use -p with -l; just omit the -p and everything will work fine. Thanks to /u/Ob101010 for pointing this out.
(For those who care, it's because I had netcat-traditional installed instead of the default netcat-openbsd.)
