Simple chat server and client with netcat

10 Nov 2019

The GNU Netcat is TCP/IP based networking utility. If you do not have netcat installed, install it first. On Arch, you must install openbsd-netcat. I accidentally installed the gnu-netcat and it did not support many of the commands and the standard examples from the internet failed. Ubuntu already has netcat installed.

After installation, use it using nc.

Open a listening port in the server: ( -l for listen, -v for verbose)
```
nc -l -v 1432
```
Connect to the server:
```
nc server_name_or_ip 1432
```

If it succeeds, cursors on both of the computers will wait. Now type text in one terminal to send it to the other. Congratulations, you have a highly insecure client-server setup running.
