You can enter a line like this to your /etc/apt/sources.list file:
deb http://smoke.silmor.de/debian dist extraThe dist keyword must be replaced by the distribution of Debian or Ubuntu that you want to target. After that you can install MagicSmoke with Apt:
apt-get update apt-get install magicsmoke2-client magicsmoke2-server magicsmoke2-doc
Alternatively download the packages from the pool directories (Debian; Ubuntu) and install them with dpkg -i package.
Download the Windows packages...
Download the *.dmg file of the newest version, open it and drag the contained *.app to a place where you want MagicSmoke to be installed. It is recommended to move the app to your hard drive, to make it easier to start next time.
