Is this software support multicast udp?

I want to know multicast's meaning in this repo.

Yes, it uses https://github.com/LibVNC/libvncserver/tree/multicastvnc (the client part) internally. You can find background info here: https://edoc.hu-berlin.de/bitstream/handle/18452/14818/beier.pdf?sequence=1&isAllowed=y

Thanks. But I do not why it does not work. I open two instances of this software in two win7 systems.
Then I input IP:5500 to one computer and another one listen to 5500. I use multivnc 0.5 from http://multivnc.sourceforge.net .

I also test on Arch Linux with latest code. I open two instances on the same host.
When connect to 127.0.0.1:5500 , in termial I see PM About to connect to '127.0.0.1', port 5500.
The other one shows PM About to connect to '', port 5900 .
Then there is no response any more.

What kinda server are you using?

[nkcfc]

I use Intel NUC. When I play with other multicast software in my LAN recently, there is no problem.
I also use Archlinux to connect to XP's multivnc. In the side of XP, I can see Incoming Connection.
Then there is no response any more.

Please read the docs. You need a special MulticastVNC-enabled server that speaks the protocol.

[nkcfc]

Oh, sorry. Can you tell me some MulticastVNC-enabled server, linux and windows? Is any vnc server based on libvncserver can be used. I see some software on https://github.com/LibVNC/libvncserver, but only "VNC for KDE" can be used.

[bk138]

Yes, you can use https://github.com/LibVNC/libvncserver/tree/multicastvnc to build a server, for instance https://github.com/LibVNC/libvncserver/blob/multicastvnc/examples/multicast.c

Now I use ubuntu's krfb(KDE Desktop Sharing) with LibVNCServer 0.9.11 as vnc server .
Using MultiVNC 0.6 on Arch linux as a client. I can use ip:5900 to connect to the vnc server.
But It use tcp instead of udp. Can I use multicast udp to connect it?

[bk138]

Well. No. You need a special MulticastVNC-enabled server. Odinary VNC servers or client will not do.
