 6. Create a short bash script inside the dispatcher directory that will launch connection-specific-ssh-config. For instance, you might name this file ```/etc/NetworkManager/dispatcher.d/99-launch-connection-specific-ssh-config```

   This will take the two important variables which NetworkManager has passed along to your launcher script, and pass them along to connection-specific-ssh-config

 The above configuration file will instruct the script to use the ssh configuration file */home/mike/.ssh/config-work* while you're connected to one of your work connections *Work Connection - Main Office* or *Work Connection - Garys Office*, on either of your wireless adapters *wlan0* or *wlan1*. When you get home and connect to your *My Home Connection (Oh Joy)* connection on *wlan0*, the config file */home/mike/.ssh/config-home* will be used instead. Finally, the configuration file */home/mike/.ssh/config-default* will be used when *wlan0* connects to some undefined network.
 
-The script works by simply creating a symlink where your original ssh configuration file was (typically *~/.ssh/config*), pointing to the ssh configuration determined to be the one you want active. Note that this of course means the script will fail (for safety reasons), if your original ssh configuration file still exists as a normal file.
