ARD Protocol

Question

ARD Protocol

Hi,

I'm interested in using the VNC extensions the Apple Remote Desktop (ARD) protocol uses for Screen Sharing in my application.

Other software such as JollyFastVNC ( http://www.jinx.de/JollysFastVNC.html) and MochaVNC ( http://www.mochasoft.dk/vncce.htm) support ARD.

Is it possible to get the protocol specification for ARD (or just the extensions to the VNC protocol)?

Thanks,

Sandeep

I'm not aware of any extensions Apple has made to VNC, but if there are, they would be in the developer documentation if Apple has made them public:

Hi Dave,

Thanks for the link, unfortunately there was no information on VNC/ARD there.

The AppleVNC server supports security types 30, 2, and 35 however only 2 is documented in the RFB protocol spec (www.realvnc.com/docs/rfbproto.pdf).

There are also other encodings the Screen Sharing app (VNC client) supports which are undocumented (0x0000044C and 0x0000044D for example).
