A Rare Collection Of Linux Commands

How to do simple chat in Linux with TCP-IP ?
  • netcat
  • telnet
Steps :
  1. Initiate netcat in a logical Port of Machine A
    nc -l 10000

Here 10000 is a logical Port. You can assign 2 ^ 16 Ports. But some are default ports already. This means the service started over network on the port. A normal man nc briefs about it.

  1. Now Connect using Telnet from the Machine B (or) local machine (Machine A):
  • From another Machine like said (Machine B)
#telnet ip 10000
telnet localhost 10000

A simple TCP/IP Session has been implemented in a logical port and can read/write (Means Normal chat :)).
