= Installing VNC =
Note: The [[addusr]] script will automatically do these for you if you specify that you want a new vnc session added.

Firstly ensure that vncserver is installed, package name is typically {{{vnc-server}}} . To ensure that VNC is always available and restarting if killed. It need to be added to {{{inittab}}} .

{{{
 /etc/inittab
}}}
Add a line similar to the following to the mentioned file..

{{{
 v5:345:off:/bin/su - ccc -c /usr/local/bin/inittab_vnc >> /var/log/vnc.ccc 2>&1
}}}
Note that this line is inactive as specified by '''off''' . Upon successful configuration this will be changed to '''respawn''' . Next {{{inittab_vnc}}} has be to installed, this is a perl script which must be modified each time a VNC session is added or removed. There is a copy stored locally on robin, alternatively a copy may be obtained from a client who recently started using VNC. Such as [[TJMBrisbane]] or VNC.

Once installed the array %displaymap is the only place where modification is required.

{{{
%displaymap = (   'ccc' => 5, );
}}}
The above array shows that there is only one VNC session, available for the user ccc on display 5. Next a password for that user much be created. To accomplish this, you must switch to that user using {{{su - ccc}}} and execute {{{vncpassword}}} . This will create a password for the current user in the home directory. It would of greater benefit if the password file and the below mentioned {{{xstartup}}} be store in {{{/etc/skel/.vnc/}}} so when a user is created the appropriate files are copied.

{{{
 $HOME/.vnc/passwd
}}}
The {{{inittab_vnc}}} program depends on the user's home directory being in a specific location. Ensure that home directories are being correctly created. The default directory configuration must be set such that new users have correct paths in {{{/etc/default/useradd}}}.

{{{
 GROUP=3232                        # Non default value  HOME=/u/cc/usr                    # Non default value  INACTIVE=-1  EXPIRE=  SHELL=/bin/bash  SKEL=/etc/skel
}}}
Ensuring that the above is correct, the full path of the password will be as follows:

{{{
 /u/cc/usr/ccc/.vnc/passwd
}}}
An {{{xstartup}}} script must be created in the same directory as the password file and executes the following commands upon the establishment of a session

{{{#!/bin/sh . /u/cc/usr/common.sh export NODEID="vnc$DISPLAY" # exec /u/cc/std/binx11/ccmenubar exec fvwm }}} To test the VNC session, execute the {{{inittab_vnc}}} as the user {{{ccc}}} . Then opening vncviewer for either Linux or Windows specify the machine's IP (likely VPN) address and session number which in this case is 5 after pressing connect you will be asked for a password.

Lastly you should be connected. To ensure that {{{inittab_vnc}}} is run automatically edit the inittab file and replace '''off''' to '''respawn''' . This will allow the session to be started automatically. The parsing of inittab can be forced by executing the following:

{{{
 /sbin/init q
}}}
To set up the VNC terminal on the client side, see: [[VNCTerminal]]

= Create new VNC in CentOS6 =
Add new user to /u/ccr.14/usr/vncusers.sh advancing a number

#!/bin/bash USER[1]='jon' USER[2]='kafu' USER[3]='bernie' USER[4]='jenny' USER[5]='gaurav' USER[6]='boris'

Add new number to start up string ACTIVE_VNCSCREENS in /etc/init/start-xvncs.conf

Start new VNC session:

initctl start xvnc VNC=6

== Setup VNC ==
When setting up VNC for replacement of guacamole.  don't forget to:

1. set up a VPN connection. you did not do this for x2x_geogianna.   Always use pptp vpn first and openvpn is a last resort.  Don't forget to  untick use default gateway.

http://customers.crecom.com.au/vnc/vnc-P5_0_5-x86_win32_viewer.zip

2. Always use the RealVNC 5.0.5 first.  only tick scale to window size.  remove the menu key. set shared to false.

if the connection flash in the begining, untick "adatpt to network speed" and use best network quality

3. Set up shortcut on the desktop.  be sure you put the ccicon.ico file  in the program files (x86)/RealVNC directory and not in the downloads  directory.

3.1 to set up shortcut , first click save connection to a file.

3.2 open the file to using the vncviewer.exe.

3.3 short the the file to be on the desktop.

3.4 change the icon of the file to the control icon.
