  1. /*
  2. Server side By Jonah
  3. Free release
  4. logs the IP of the user connecting, along with a couple other cool things
  5. Small update:05/21/17
  6. If you would like to add users upon screen, compile like the following
  7. gcc server.c -o server -pthread -DUser
  8. if you just want to screen it, then do the following
  9. gcc server.c -o server -pthread
  10. Btw, if you plan on modifying this, at least give credit, thanks.
