ubuntu multiple Simultaneous independent remote (desktop like ) connections

vnc - ubuntu 14.10 multiple Simultaneous independent remote (desktop like ) connections - Ask Ubuntu

https://askubuntu.com/questions/581979/ubuntu-14-10-multiple-simultaneous-independent-remote-desktop-like-connection

Here are the things worked for me.. (success using this tute http://www.howtoforge.com/how-to-install-vnc-server-on-ubuntu-14.04 and kudose for Charles Tassell for right directions and advice)

What I did is as follows,

(1) run sudo apt-get update && sudo apt-get upgrade

(2)run sudo apt-get install gnome-core xfce4 vnc4server

(3)then add users (vncserver/unix)

sudo adduser test1   

(you will have to fill details afterwards for the user, I have added 3 users (test1, test2, test3 etc for vnc server)

(4)Then you have to switch users one by one and run vncserver and add password for vncuser login (I have three vnc users, so that i had to repeat this for all three user test 1, test2, test3)

su - test1

then run

vncserver

out put will be like this prompting for a vnc password..

You will require a password to access your desktops.Password:Verify:xauth:  file /home/test1/.Xauthority does not existNew 'server1:1 (test1)' desktop is server1:1Creating default startup script /home/test1/.vnc/xstartupStarting applications specified in /home/test1/.vnc/xstartupLog file is /home/test1/.vnc/server1:1.log

(5) Important : you will have to replace /home/test1/.vnc/xstartup content with below (Else you will not get the desktop, instead you will stuck with blank screen without user interfaces or menus )

vim /home/test1/.vnc/xstartup

and add

#!/bin/shunset SESSION_MANAGERunset DBUS_SESSION_BUS_ADDRESSstartxfce4 &[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresourcesxsetroot -solid greyvncconfig -iconic &

(6) startup script for the vncserver was created using "Further I will make the startup script for the vncserver like this" section of this tute

sudo vim /etc/init.d/vncserver

and add below content..

#!/bin/bashunset VNCSERVERARGSVNCSERVERS=""[ -f /etc/vncserver/vncservers.conf ] && . /etc/vncserver/vncservers.confprog=$"VNC server"start() { . /lib/lsb/init-functions REQ_USER=$2 echo -n $"Starting $prog: " ulimit -S -c 0 >/dev/null 2>&1 RETVAL=0 for display in ${VNCSERVERS} do export USER="${display##*:}" if test -z "${REQ_USER}" -o "${REQ_USER}" == ${USER} ; then echo -n "${display} " unset BASH_ENV ENV DISP="${display%%:*}" export VNCUSERARGS="${VNCSERVERARGS[${DISP}]}" su ${USER} -c "cd ~${USER} && [ -f .vnc/passwd ] && vncserver :${DISP} ${VNCUSERARGS}" fi done}stop() { . /lib/lsb/init-functions REQ_USER=$2 echo -n $"Shutting down VNCServer: " for display in ${VNCSERVERS} do export USER="${display##*:}" if test -z "${REQ_USER}" -o "${REQ_USER}" == ${USER} ; then echo -n "${display} " unset BASH_ENV ENV export USER="${display##*:}" su ${USER} -c "vncserver -kill :${display%%:*}" >/dev/null 2>&1 fi done echo -e "\n" echo "VNCServer Stopped"}case "$1" instart)start $@;;stop)stop $@;;restart|reload)stop $@sleep 3start $@;;condrestart)if [ -f /var/lock/subsys/vncserver ]; thenstop $@sleep 3start $@fi;;status)status Xvnc;;*)echo $"Usage: $0 {start|stop|restart|condrestart|status}"exit 1esac

to make it an executable run the following..

chmod +x /etc/init.d/vncserver

(7) To make vnc desktop sessions allocated for users at start up automatically, create following script in /etc/vncserver

sudo mkdir -p /etc/vncserversudo vim /etc/vncserver/vncservers.conf

add this in vncservers.conf (this is because i have my users as test1, test2, test3 change it according to )

VNCSERVERS="3:test3 2:test2 1:test1"VNCSERVERARGS[1]="-geometry 1024x768"VNCSERVERARGS[2]="-geometry 1024x768"VNCSERVERARGS[3]="-geometry 1024x768"

(8) Then run

sudo `update-rc.d vncserver defaults 99`

(9) reboot server (you are almost done by now) step 10 and the rest is how to login part

(10)download http://www.realvnc.com/download/viewer/

enter servername/ipaddress and session id for example my server is 172.16.70.17 and if i use 172.16.70.17:2 it will login to test2 user desktop.. and 172.16.70.17:3 will login to test3 user desktop like wise

make sure encryption to be selected "Prefer off"

Then you can access your desktop and applications in this manner..
