Weird problem with UltraVNC Viewer

[occhigrigi]

Hi everybody,
i've been using ultravnc viewer from long time without any problem.
Starting from wine-1.2-rc2 when i'm connected to a vnc server i cannot close anymore the viewer window and when I try to close the window it sends an ALT+F4 to the application running in the vnc server !!
With wine until version 1.2-rc1 the viewer windows close as expected.

In console there are no messages and the application runs PERFECTLY in every aspect (a platinum one).

I'm running on openSuse 11.2 64bit.
Tried with kde with compiz and with Icewm without compiz, same problem.
The application is freely available from http://sc.uvnc.com/download/click.php?id=51

Any idea ?

Please run a regression test and file a bug. http://wiki.winehq.org/RegressionTesting

You can also have a look at ssvncviewer from this:
http://www.karlrunge.com/x11vnc/ssvnc.html (Might replace UltraVNC
viewer rather than fix it though...)

It supports almost all (if not all) UltraVNC extensions and runs
natively... (The interface can't be compared though..)

The only reason I'm using ultravnc viewer is what it supports user/password authentication against a windws domain. Otherwise i should have used the good old native vncviewer
Going to try ssvncviewer as advised.
For the regression test i hope to find time.

The unix SSVNC viewer supports ultravnc mslogon.

Note that the ultravnc mslogon password exchange protocol is extremely weak and the windows domain username and password can be recovered a few seconds. So it is a very good idea to use some sort of additional encrypted tunnel when using ultravnc mslogon (including when using the ultravnc viewer)

Can this be run through ssh X tunneling to the server?

Just wondering what protocol that UltraVNC uses.

VNC can be tunnelled through an ssh port redirection (-L ssh option.) But I don't think the ssh X tunnelling (-X or -Y option) would work; that redirects in the opposite direction (like -R) and also does some things special to the X11 protocol.

For SSH, one would need to install an ssh server on the UltraVNC server side (ultravnc knows nothing about the SSH protocol.) One can set up an ssh server on windows, but I have never done it.

Or one could use SSL tunnelling instead of SSH by using stunnel. That I have done on windows for tunneling VNC and it works fine.
