Does anybody know how to add vnc-java for resumable sessions?

Does anybody know how to add vnc-java for resumable sessions?

Are you talking a bout using a java client? Should be the same process. Let me explain. "Resumability" of a session is a property you set on the vnc server (parameter passed to Xvnc on the server side). It should be resumable based on this property no matter which client you use. So, whatever page you found for setting up vnc java applet and follow this thread to set up resumable session and it should work. This is how I am set up.

Let me know if you are running into issues.

CU_:
No, I meant of equivalent of using next line:
vnc4server :5 -httpport 6505 -httpd /usr/share/vnc-java
this command create listener for http request on port 6505. It is allow to connect to server by command http://xx.xx.xx.xx:6505
vnc-java client will be downloaded automatically and client will connect to port 5905.

I tried to use this code for xinetd:

service Xvnc
{
        type = UNLISTED
        disable = no
        socket_type = stream
        protocol = tcp
        wait = yes
        user = root
        server = /usr/bin/Xvnc
        server_args = -inetd :5 -httpport 6505 -httpd /usr/share/vnc-java -query localhost -geometry 1024x768 -depth 16 -once -fp /usr/share/fonts/X11/misc -DisconnectClients=0 -NeverShared passwordFile=/root/.vnc/passwd -extension XFIXES
        port = 6505
}

But it don't work.

Just for info. How to install it on ubuntu server without any X.
All operation was made under root account. If you are using another account you should modify
passwordFile=/your_user_name/.vnc/passwd

apt-get install screen xfce4  mousepad thunar-archive-plugin vnc4server vnc-java xserver-xorg-core xdm xinetd 

vnc4server :55
inter password for vnc
vnc4server -kill :55

------------------------------------------

edit xdm parameters:
---------------------------------------------------------------------
xdm

These changes are only required, if your display manager is XDM. If you use GDM or KDM, see the next sections.

Open /etc/X11/xdm/xdm-config with your favorite editor.

Look at the last line : "DisplayManager.requestPort: 0"

Comment it out by inserting a ! at the beginning of the line. File: /etc/X11/xdm/xdm-config

!DisplayManager.requestPort: 0

Edit /etc/X11/xdm/Xaccess and uncomment the line " '* #any host can get a login window" by removing the single quote. You could also change it to 192.168.0.* for some security
(from: http://en.gentoo-wiki.com/wiki/XVNC_Server#xdm )
--------------------------------------------------------------------

edit services for xinetd:

nano /etc/xinetd.d/Xvnc

 service Xvnc
{
        type = UNLISTED
        disable = no
        socket_type = stream
        protocol = tcp
        wait = yes
        user = root
        server = /usr/bin/Xvnc
        server_args = -inetd :1 -query localhost -geometry 1024x768 -depth 16 -once -fp /usr/share/fonts/X11/misc -DisconnectClients=0 -NeverShared passwordFile=/root/.vnc/passwd -extension XFIXES
        port = 5901
}

I switched to NoMachine NX.

Install SSH, NX client, NX node and NX server on the Ubuntu box you want to remote into and install NX client on the other PCs.

I have NX client intalled on XP, Vista and Ubuntu Jaunty desktop. They can all remote to the Ubuntu box running NX server flawlessly.

It's faster than VNC and is more secure because it uses SSH to authenticate users.

NX is free, it works out of the box with the default configuration and you also have the ability to resume sessions with NX.

Hi, my problem is that the host machine has got me logged in, so when I try to connect it shows a message asking for permission.

Any solution?

Thanks,

Chris

The default tools that have come with Ubuntu since Feisty have allowed you to configure resumable remote desktop sessions simply by going to system > preference > remote desktop. That's why this tutorial is in the "Outdated tutorials and tips" section.

Have you tried to configure remote desktop via this method and failed?
