Of course, when using ARD 3.2.2 on systems using Mac OS X 10.4.11 or 10.5.6, I can connect/control all versions of ARD - believe backward supports is back to rev 1.2x -Note- ARD 3.1 supports VNC port 5900 over encryption (typically port 22)

Thank you for your bug report. The issue is an upstream one and it would be nice if somebody having it could send the bug the to the people writting the software (https://wiki.ubuntu.com/Bugs/Upstream/GNOME)

Original bug report was against jaunty but I can confirm it on karmic as well with the following package versions. (the bug is likely to be in the authentication code in libgtk-vnc-1.0-0 rather than vinagre itself imo).

libgtk-vnc-1.0-0 0.3.8-2ubuntu2
vinagre 2.27.5-0ubuntu2

I have raised it upstream here:
http://bugzilla.gnome.org/show_bug.cgi?id=590831

[Dominic Evans (oldmanuk)]

Hmm, launchpad lost the version numbers?

libgtk-vnc-1.0-0
    0.3.8-2ubuntu2
vinagre
    2.27.5-0ubuntu2

[Dominic Evans (oldmanuk)]

Whilst this is a known problem, that vinagre doesn't support the undocumented authentication types used by ARD server by default, a suitable current workaround seems to be to enable the "VNC viewers may control screen with password" option in system preferences. After doing this auth type 2 becomes available and vinagre can successfully connect using the given password.

I have asked upstream if they can do anything to better feed this information back to the user on failed connection.

with respect to vinagre 2.24.1 vnc control of most macs configured via ard client will fail - screen sharing seems to work well enough but is disabled on my servers

Please note that I installed Ubuntu 8.10 Server on a G5 Xserve and once logged into the server - after config (Vino remote desktop server) I was able to control the 8..10 server remotely via ARD 3.2.2 on a MacBook Pro (also worked with JollyFast 0.98.36) - however after logging out of the the Ubuntu server I was not able to control the server remotely - since it appears that the remote vnc server service is not a daemon...I know other vnc servers can run in the background - I'm now looking into the how to for this setup

[Dominic Evans (oldmanuk)]

Good news from Jonh Wendell (upstream). A working patch has been received and committed to enable support for connecting to Apple Remote Desktop servers using their proprietary authentication scheme.

This should naturally be fixed in a future release of gtk-vnc and vinagre.
