The last article teaches how to use socat by comparing it first to cat then to netcat. It skimped on socat's UDP-related features, because netcat only implements a subset of them. This article picks up where the last one left off, with respect to UDP. After this article will be one more that discusses advanced socat features.

It turns out there are a lot of subleties when dealing with UDP, even before multicast is mixed in. We'll abandon the comparisons to netcat, as we've exceeded what netcat can do. But first a quick reminder of one way socat does UDP. 

socat as a UDP server on port 11111.

socat STDIO UDP-LISTEN:11111
