vnc in opensuse 11.1 (and probably 11.0)

whschimmel · 02-04-2009, 05:25 AM

Just installed OpenSUSE 11.1 and detected a problem:

When I was using OpenSUSE 10.3 I could setup my vnc settings perfectly. In Yast I could enable remote administration (vnc) and in the Sax2 (display settings) I could enable vnc for the current X screen with a password.

When I switched over to OpenSUSE 11,0 and now to OpenSUSE 11.1 I can't find the settings for enabling vnc for the current X screen.

When connecting from my PC2 (WinXP Pro SP3 with realVNC) to wy PC1 (OpenSUSE 11.1 KDE3.5, with vnc enabled in yast)
I can only connect to local ip:1 (999.999.9.99:1) or through a browser (http://999.999.9.99:5801). But I see only a black and white screen with a cursor. I can't login.

When trying to connect the normal way with vnc in windows (local ip:0, like 999.999.9.99:0) I get the error:

'failed to connect: Connection refused (100161)'

Does anybody have a workable solution or workaround for this problem?

tnx,

Wouter

To connect to your current X session, you'll want to use x11vnc. To use x11vnc with a password, first set the password with the command

Code:

x11vnc -storepasswd

and then start the vnc server

Code:

x11vnc -usepw -display :0

created an vnc password

and gave the "x11vnc -usepw -display :0" command, when I do this I see the following:

Have you tried the x11vnc '-ncache' VNC client-side pixel caching feature yet?

The scheme stores pixel data offscreen on the VNC viewer side for faster
retrieval.  It should work with any VNC viewer.  Try it by running:

    x11vnc -ncache 10 ...

after giving the above command I can connect with my windows pc to my linux pc, but as soon as I close RealVNC in windows i see the following message in the terminal of the linux machine:

when I try to connect a second time to my linux pc from my windows pc, I get the error:

How can i setup x11vnc so its running constantly and accepts all connections?

tomslick · 02-06-2009, 01:10 AM

follow these steps and you will have what you want.

HOWTO: Setup x11vnc as krfb alternative.

whschimmel · 02-06-2009, 05:01 AM

Thanks guys,

its working, I setup my vnc with howto provided. Now I have vnc working properly in OpenSUSE 11.1 (KDE 3.5)!!!

I connected locally from my windows pc to my opensuse pc. This worked perfectly. Also when I close the connection, its now possible to reconnect the same way.

This weekend I will test it from an external location. but my router is setup the right way, so I don't expect any problems.
edit: Externally its working too!!

greetz,

Wouter
