What happens next?

^ I haven’t done any interviewing for a while but I went through a period of growth in one of the companies I worked for where we were feverishly expanding the development team, so we had to be a little more systematic in our approach to interviewing. Instead of just having an open conversation with candidates to see where it led (which is what I’d previously done in such situations), I wound up preparing a ‘standard’ set of questions. It took a few goes, but eventually I settled on a favourite question for the technical portion of the interview:

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.

1. Test if a particular TCP port of a remote host is open.

$ nc -vn 192.168.233.208 5000
