Yes, well ... let's just say that xymond has some very specific 
requirements about the TCP/IP protocol. Which the Xymon network tester 
doesn't fulfill.

(Technically, xymond expects the client to send a FIN packet - usually 
done by calling "shutdown(socket, SHUT_WR)" before it will assume that 
the entire command has been sent - and only then will it process the 
request and send a response).

Nope, same reason - telnet doesn't shutdown the session the way xymond 
expects.

So you are not doing anything wrong - it's just xymond that behaves oddly.
