Network Management System - Part 2

SSH already running.  Just need to setup X11VNC through the SSH tunnel.

sudo apt-get install x11vnc

Setup a password:

sudo x11vnc -storepasswd /etc/x11vnc.pass
sudo chmod 600 /etc/x11vnc.pass

sudo x11vnc -xkb -noxrecord -noxfixes -noxdamage -display :0 -auth /var/run/lightdm/root/:0 -rfbport 5901 -rfbauth /etc/x11vnc.pass -localhost

(put this in a script eg.

Then to change resolution (modified from - needs to be done from terminal in vnc session:

sudo gtf 1920 1200 60 -x
sudo xrandr --newmode "1920x1200_60.00"  193.16  1920 2048 2256 2592  1200 1201 1204 1242  -HSync +Vsync
sudo xrandr --addmode VGA-0 1920x1200_60.00
sudo xrandr --output VGA-0 --mode 1920x1200_60.00

again add to a script (eg.

note that if you're on the box not vnc - then use:

xrandr -s 1920x1200_60.00

Change desktop if required

Settings/Settings Manager/Desktop

Change SSH port

sudo nano /etc/ssh/sshd_config

#change the port

#check firewall settings
sudo ufw status verbose

#change firewall settings - open new port
sudo ufw allow <insert new port>/tcp

#restart openssh
service ssh restart

#after reconnecting with ssh client on new port change firewall to close port 22
sudo ufw delete allow 22/tcp

#recheck firewall settings
sudo ufw status verbose

then check

netstat -an | grep "LISTEN "

that will do for now - next part we will begin by installing bandwidthd
