HOWTO: Set up VNC server with resumable sessions

[popie]

Here are the instructions I use, and they work in v8.04.

VNC Server w/Resumable Sessions on Ubuntu
Works in Ubuntu 7.04, 7.10, 8.04, and Mint 4 (Daryna)


Make these changes while logged into gnome:

• Go to System -> Administration -> Login Window (General tab) and uncheck "Disable multiple logins for a single user."
• Now go to the Remote tab. Change Style: to "Same as Local"
• Still on the Remote tab, click "Configure XDMCP," then uncheck "Honor indirect requests."
• Enable Universe repositories in Synaptic. (this wasn't necessary in Ubuntu 8.04)

The remaining changes can be made while SSH'd into the system, or in a terminal window:

• Edit /etc/gdm/gdm.conf-custom

sudo nano /etc/gdm/gdm.conf-custom

add the following two lines to the existing [security] and [xdmcp] sections:

[security]
DisallowTCP=false
[xdmcp]
Enable=true

• Install packages:

sudo apt-get install vnc4server xinetd

• Set the VNC password

sudo vncpasswd /root/.vncpasswd

• Create a new file Xvnc to add the vnc service to xinetd:

sudo nano /etc/xinetd.d/Xvnc

Paste these contents into the file:

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/.vncpasswd -extension XFIXES
        port = 5901
}

• Reboot

That's it. I've used these exact instructions on three Ubuntu 8.04 installs without a hitch, as well as 7.04, 7.10, and Mint 4. Good luck.

Just so I'm clear on this, is there a way to set up VNC on Kubuntu so that the remote user has the option of logging in using their own session and logging into the existing session to take control of the PC?

I could do with being able to use both options.

vncpasswd: error while loading shared libraries: libstdc++-libc6.2-2.so.3: cannot open shared object file: No such file or directory

Why do I keep getting this when I try to change the password??

I can download that library as it says it doesn´t exist...

Search your computer for .vncpasswd
Maybe it's not in /root

[mikeduffy13]

I don't get any results when searching for .vncpasswd.

If I search for just vncpasswd I get:

user@machine:~$ locate vncpasswd
/etc/alternatives/vncpasswd.1.gz
/etc/alternatives/vncpasswd
/home/rnccadmin/Desktop/vnc-4_1_2-x86_linux/vncpasswd
/home/rnccadmin/Desktop/vnc-4_1_2-x86_linux/vncpasswd.man
/usr/bin/vncpasswd
/usr/bin/realvncpasswd
/usr/bin/realvncpasswd.real
/usr/local/bin/vncpasswd
/usr/share/man/man1/vncpasswd.1.gz
/usr/share/man/man1/realvncpasswd.real.1.gz
/usr/share/man/man1/realvncpasswd.1.gz
/var/lib/dpkg/alternatives/vncpasswd

If I just try and start the Xvnc I get the same library error message...

[chelrob]

Maybe try creating .vncpasswd in root?

[mikeduffy13]

Even if I create .vncpasswd in /root, still when I issue the command
:~$sudo vncpasswd /root/.vncpasswd I get the same library error...

[chelrob]

Perhaps their's a problem with your C compiler's tool chain?

Are you able to install binaries with

.configure

and

make

?

[mikeduffy13]

When I first installed unbuntu I could...I haven't tried lately. Where can I find a .bin file to install for a test? sourceforge?

...sorry, i'm still new to linux...

[chelrob]

Sorry, I meant source not binaries.

I found this in the Ubuntu forums... you can try to build and install nano from source:

If you have gcc installed you can download nano's source 
(http://www.nano-editor.org/) 

Then type:

tar -xzf file-name
cd new-directory
../configure
make
make install
