Hi Robert
The server only sends the option if the client requests it. And the
client has to do something sensible with the reply.
Suggest using your favourite network sniffer (tcpdump/snoop/wireshark,
etc) to have a look at what is being requested and sent.
3.0.1 is truly ancient, circa 2003/2004, but this is pretty simple
stuff, so it's not likely to be the version that's the problem.
