Hi Bill!
Ahh..! Again new discovery... udp_daemon. ft8sim was also quite handy
when I discovered it some time ago. It just does not come with package
installs, but self compile makes it.
Just made a listener with perl and learned in hard way that REUSEADDR is
needed. My listener is just a raw dump without decode, so udp_daemon
looks better.
Anyway now I have wsjt-x on 20m and I have monitor results at same time
to cqrlog, to udp_daemon and to my perl listener. Looks like working.
I use also qso initiate and color commands from cqrlog monitor to wsjtx.
They worked with only cqrlog in multicast group, and I can not see any
reason why they would not work when several listeners are online.
Still have to work some qsos to be sure all is ok. (this was too easy to
modify :-O )

Hi Saku,
that's no problem, use message_aggregator in the WSJT-X distribution.
There is also a small command line utility udp_daemon. Neither do
anything in particular as they are to demonstrate WSJT-X UDP Message
Protocol facilities. Both support multicast group addressing.
There are only a couple of minor gotchas with multicast. If you wish
to run multiple servers on the same network interface you must set the
SO_REUSEADDR socket option, and if you try and join an IPv4 multicast
group you must bind to your listening socket for IPv4 only, i.e. you
can't bind to the dual-stack ANY address, so usually you bind to
"0.0.0.0" in that case. To join an IPv6 multicast group there is no
such restriction and there you would normally either bind to the
dual-stack ANY address, or for IPv6 only use the IPv6 ANY address "::"
