Service Definition

Setup your favorite services below. Define the necessary connections to use the service towards other hosts (e.g. telnet a host). You don´t have to setup the reverse ´ack´-tcp connection. Use the predefined services as a template - if possible.
The configuration-file is 'etc/config/<service>.def'.

You can use any port listet in /etc/services or the number of the port. Also variables from the Aliases definition can be used. Multiple entries are allowed in every input-field. Each port in a ´Source´ field must have a corresponding entry in the ´Destination´ field. Otherwise it will be ignored.
You can also block ports with adding a '!' in front of the port (without blank between!) - see the default definition of ftp_passive for an example.
