+The option `-t 30` configures socat to use a timeout of 30 seconds when socat reads from the socket awaiting to get an EOF (End-Of-File).
+As the container image has already been pulled, such a long timeout is not really needed.

 The echo server works as expected. It replies _"hello"_ after receiving the text _"hello"_.
