HOWTO: Set up VNC server with resumable sessions

[mssm]

Tichondrius, I observed a strange thing. Afetr starting the xinetd service, If I issue the command

$ vncviewer localhost:0

I am getting the current desktop screen but not the login screen which I obtained last time by issuing that big command.

Update : This occurred due to enabling ubuntu's built-in remote desktop feature. When I turn off this feature, the above command yields nothing. But still vncviewer localhost:1 gave the error msg. I thought if this remote desktop feature is interfering with the vncserver setup, but it's not the case.

Moreover, I should add that right now I am working in gnome desktop and my /etc/xinetd.d/Xvnc file is exactly identical to the config. you alluded to in post #14. And still, the error msg. with vncviewer localhost:1. So using kDE desktop is not an issue. I shall follow method of elimination to pinpoint the trouble, if I can. If anybody else can help us, it will be really appreciated.

Kacheng, sorry, I could not help you since I am a novice in this regard but you can try to install the tightvnc java-client from the thread I linked to in my previous post. You need to enable ubuntu's built-in remote desktop so that it can work and of course if you are behind a router, you need to fwd those ports.

sudo /usr/bin/Xvnc :2 -query localhost -geometry 1280x1024 -depth 16 -once -fp /usr/share/X11/fonts/misc -dontdisconnect -nevershared -rfbauth /root/.vncpasswd

I too am trying this on AMD 64., Following this thread I get to this point and I all I get is

Segmentation Fault

mssm - thanks, I have no problem with using vnc and the remote desktop - even can tunnel over ssh. That works great.


However, at some point I'd really like to get the XDMCP working properly and have the ability to utilize several sessions. (e.g. two people logged in at the same time).

using a fresh install of 5.10. running

 sudo apt-get install vncserver xinetd

yeilds me the following results:

Reading package lists... Done
Building dependency tree... Done
E: Couldn't find package vnc4server

what am I missing here? Do I need to add an additional installation source?

EDIT: I found the package in a different installation source. Open package manager, go to settings->repositories, clicked the 'community maintained' button.

vnc4server installed and works like a champ. Thanks!

Hi Kacheng,

Is there a How-To for tunnelling VNC over SSH? Some pointers would help a lot ... thanks

[Tichondrius]

Yes, you are suipposed to enable the extra repositories because vnc4server is from the universe repository which is not enabled by default.

Hi cosmix, good to learn that you are running vnc on one machine? Did you follow Tichondrius's how-to? Are you behind a router? I am still trying hard.

Yes here's one:

There are many others.

Hi Kacheng, thanks for the link and thanks for your appreciation before.

I found that freenx is much smoother less jerky and easy to install than vnc. Moreover, it supports vnc too. There is no headache for port opening and forwarding, since it uses standard ssh port and hence the whole session can be encrypted. So I switched to freenx. I followed this thread :

Good luck!
