Sending UDP packets in Linux
In my work, I often have to work with UDP and at one time I knew of a linux utility to send UDP packets from the command line, which is incredibly useful for debugging. However, I forgot what the utility was and no one I asked seemed to know what it was. Surprisingly I could not find it with a web search either. Recently I finally rediscovered it when I read a the following blog post. How could I have possibly forgotten the incredibly intuitive name “nc” which I now know is short for netcat. Slightly more intuitive, I suppose. I am convinced that a design requirement for the unix OS was that managers who happened to look over your shoulder would have no idea what you were doing.
