Installing wireshark on Ubuntu 12.04 LTD and limiting packet capture to one group, in this case the group wireshark. I’m sure you can use these instructions for other debian based distributions.
Although you’ll have to take it as read that I’ve only tested it on Ubuntu, feel free to let me know if it doesn’t and I’ll amend the instructions to suit.
First, we install Wireshark from the terminal.
I’m making the assumption that you have a working 12.04 installation that’s connected to the internet.
First, your going to add the freenx repository, then update. Followed by installing the freenx software.
sudo add-apt-repository ppa:freenx-team/ppa
sudo apt-get update
sudo apt-get install freenx-server
Now tht you have the Freenx server installed, you will want to configure it to use the ubuntu-2d session for any Freenx clients. The ubuntu-3d session doesn’t work with Freenx and will give you an error message “Failed to load session “gnome-fallback””.
sudo echo -e "\n#Use unity 2d for client sessions\nCOMMAND_START_GNOME='gnome-session --session=ubuntu-2d'"|sudo tee -a /etc/nxserver/node.conf
All done, you should be able to connect using NoMachine’s free client.
