Often referred to as the "swiss army of knife" for TCP/IP networking, [Netcat][1] is an extremely versatile Linux utility that allows you to do anything under the sun using TCP/UDP sockets. It is one of the most favorite tools for system admins when they need to do networking related troubleshooting and experimentation.
In this tutorial, I am sharing a few useful netcat examples, although the sky is the limit when it comes to possible netcat
use cases. If you are using netcat
regularly, feel free to share your use case.
Note that when you are binding to well-known ports (0-1023) with nc
, you need root privilege. Otherwise, run nc
as a normal user.
$ nc -vn 192.168.233.208 5000
Say you're running a virtual machine on your work computer. Say this machine, for whatever reason, can only connect to the internet over NAT - as in, it does not get it's own IP address. Say this VM is running a webserver, and you need a device outside of your computer to connect to it.
If only there was a way to get your work computer to 'share' it's network, so that you could get at that VM… Here's how you do it!
For all instructions, I assume your work computer is a mac
