 ## Interactive Mode
 
-Interactive mode allows you to start and stop modules manually on the fly, change options and apply new firewall rules on the fly, the basic commands are:
-
-| Command | Description |
-| ------- | ------------|
-| help | Display list of available commands. |
-| active | Show information about active modules. | 
-| exit | Close the session and exit. |
-| sleep SECONDS | Sleep for the given amount of seconds. |
-| get NAME | Get the value of variable NAME, use * for all. |
-| set NAME VALUE | Set the VALUE of variable NAME. |
-
-For instance you can view a list of declared variables with `get *` and set new ones, for example `set some.new.variable some-value`, for a list of every module and its parameters, issue the `help` command:
-
-    192.168.1.0/24 > 192.168.1.17  » help
-
-    Basic commands:
-
-                      help : Display list of available commands.
