A 64-bit version of Linux is required to run Usfos. Ubuntu is the recommended distribution. It is easy, just follow these steps:

1. Create the folder structure in your home-folder called bin/usfos/etc:

   mkdir -p ~/bin/usfos/etc

   
   

2. Go to usfos.no and download the Linux-modules Usfos, Dynmax and Xact, and place them in the newly created bin/usfos directory. More modules and tools can be downloaded later if you need that.

3. Extract the downloaded .gz-files into the same folder. The compressed .gz-files can now be deleted.

4. Make the files executable by opening a command window and run the following commands:

   
   

   cd bin/usfos # To enter the usfos installation directory chmod +x * # To make the files executable

   
   

5. You need to set some environmental variables. Open the file .profile in your home folder, and append the following lines to the end of the file:

   
   

   # Usfos specific variables export PATH="$PATH:$HOME/bin/usfos" export USFOS_HOME="$HOME/bin/usfos"

   
   

6. Place the Usfos license key in the bin/usfos/etc directory.

7. You have now successfully installed Usfos. Since the .profile file is read only at login, you might need to log out and in before the variables is updated. You can then execute Usfos from anywhere in your environment.

Installing additional modules

Additional modules can be downloaded from usfos.no, and is installed just like the programs above. Download the files into the ~/bin/usfos/bin folder, use the gunzip tool to uncompress the files and make them executable. If you want to install the postfos tool, simply do the following:

cd ~/bin/usfos                                            # Change directory
wget http://www.usfos.no/download/Linux/files/postfos.gz  # Download the file
gunzip postfos.gz                                         # Uncompress the file
chmod +x postfos                                          # Make the file executable
