Download ntop addon from here:
transfer to /root on ipcop machine
from ssh session on icop:
cd /usr/lib
ln -s
cd /root
tar -zxvf ntop_ipcop_1.4.8.tar.gz
cd ntop
from ipcop gui, refresh view and choose NTOP from SERVICES menu
Click Start button, and refresh
There is a link now shown for Ntop Webinterface (http)


The ln -s  is necessary due to a change since ipcop v 1.4.18

Ubuntu Server 8.04.3 – freenx setup

November 17, 2009 Leave a comment

Sorry for the brevity – it was quickly written to fill a need. I will try and flesh it out later. This is a minimal ubuntu server setup with just enough gui to function with nx client. We use these for remote access terminals on low powered equipment.

Install ubuntu server 8.04.3 from CD

only select openssh-server, use all other defaults

login and note ip address


change ssh port to non-standard port e.g. 8888

sudo nano /etc/ssh/sshd_config

change port 22 to port 8888, save and exit.

sudo reboot

From remote machine login with ssh

ssh <user>@<ip addr> -p 8888

sudo su

apt-get update

apt-get upgrade -y

–let it work for a while


log back in after a few minutes

sudo nano /etc/apt/sources.list

add this at the bottom:

deb hardy main

deb-src hardy main

save and update key, then reload repositories:

sudo apt-key adv –recv-keys –keyserver 2a8e3034d018a4ce

sudo apt-get update

Now actually install freenx:

sudo aptitude install freenx

wait 5-10 minutes for it to finish

sudo /usr/lib/nx/nxsetup –install

You should be ready to connect with NX Client from nomachine

optionally Install a few items you may need later:

sudo apt-get install gnome-terminal firefox tsclient libstdc++5
