dnc: demo version of nc(1)

dnc is a very simple version of the venerable nc(1) that's intended for demo purposes by explaining precisely what it's doing and giving users a little more control about how it operates.

Synopsis

Listen for TCP connections on port 8080 on all local IP addresses:

# dnc -l -p 8080

Establish a TCP connection to a server listening on 127.0.0.1 port 8080:

# dnc 127.0.0.1 8080

TODO

  • basic server
  • basic client
  • allow setting TCP keep-alive options
  • allow setting listen backlog
  • allow disabling poll(2) -- need a REPL?
