Krfb/KRDC display error

I am connecting between two Suse 11.0 machines with KDE 3.5.9

The remote machine runs Kfrb set to accept remote logins without questions and is advertising it’s presence.

The connection is made OK but the screens start looking like a stereo pair and the large blocks of colour begin to dominate the screen.

The remote is off-line now but I imagine it has the default Kfrb.

KRDC is 4.1.2

A normal VNC connection works flawlessly but I want to connect to an already active session.

Bug 162493 krfb produces garbled display

This is the one. I guess that plan will will have to wait, and for some time by the look of it.

You can do this with vnc.

I do this all the time to give my mother support on her openSUSE-10.2 Linux PC. She lives in Canada. I live in Europe. When she has a Linux problem, we pick a convenient time for both of us (which is the biggest problem due to the 9 hour time difference) and with vnc I join her already active desktop session. I can move her mouse, launch applications (and she will observe everything I do on her PC).

Then we chat over the phone, and sort her problem/train her on Linux.

Of course 80% of our chatting has nothing to do with PCs, but its kind of neat to provide her support a continent away.

Yes but that is what I am doing Kfrb is the server side and KRDC is the client . Although maybe if I downgrade the server to 10.2 it will work.

I can also do this with vnc with pure 10.3 PCs, … or with a mix of 10.3 and 11.0 PCs, or with 11.0 PCs.

I don’t understand why you are consider downgrading to 10.2

Well my limited unnderstanding is that I need Kfrb running on the server side so that I can log into the active session, but for me and others as well (see link above) this does not work. Probably there is some other way that I do not know about to do this. I would be grateful for a few hints.

To put things more clearly since I may be misusing the termininology here, I have a server in the cellar that could be downloading the new 11.1 beta5. Then the wife and kids all want to watch videos and surf. I have to tell ktorrent to stop for a while. I want to log into that running KDE desktop and change things there. If I log in with VNC I will be running a second session on the server with no control over the already running services.

Maybe what I want to do is log into the local session with VNC, is this possible without Kfrb.

>the :0 is the first session

I remember reading that not all vnc clients can connect to :0

somrthing to try when I get home…

Got the new lappy yet?

As you may have surmised, I never use Krfb nor KRDC. But I do have vnc working well.

I do it all from a konsole. What can I say? I’m old fashioned. In truth, Yaloki (who goes by the user name pbleser) taught me how to do this. …

I have x11vnc and tightvnc installed on both LinuxPCs. I then access the PC by running x11vnc by the following (piping the vnc display over ssh which is reasonably secure):

PC-1 is an openSUSE-10.3 PC
PC-2 is an opensuse-11.0 PC

From 1st konsole on PC-1:
ssh -t -L 5900:localhost:5900 oldcpu@ip-address-of-pc-2 ‘x11vnc -localhost -nolookup -nopw -display :0’
… and then entered password for user “oldcpu” on PC-2:

From 2nd konsole on PC-1
vncviewer -encodings “tight copyrect hextile” localhost:0

And I successfully connected to PC-2, piping its vnc desktop display back to pc-1. This is the active desktop. And I can close and rejoin the session any time.

I did have to open the firewall on each PC to port 22 and port 5900.

In truth, because I did this over the internet, through a router, I added a few more things for security, but the above works well on an internal LAN.

Well that works… Thank you for the help I did it quick and dirty much too much of a security leak even for at home I will just use tighten things up next.

Thanks once again.
