-
- This section is used to set the server informations.
-
- Format:
-
- +<Server DNS name>:<Server IP>:<Geographic location>:<Port>
-
- <AdminInfo>
-
- This section is used to set the server's administrative information.
-
- Format:
-
- +<Location>:<Server type>:<Admin's name>:<Admin's email address>
-
- <ListenPort>
-
- This section is used to set ports the server is listenning.
-
- Format:
-
- +<Local IP/UNIX socket path>:<Remote IP>:<Port>
-
- <Logging>
-
- This section is used to set various logging files, their paths
- and maximum sizes. All the other directives except those defined
- below are ignored in this section. Log files are purged after they
- reach the maximum set byte size.
-
- Format:
-
- +infologfile:<path>:<max byte size>

-
- <ConnectionClass>
-
- This section is used to define connection classes. These can be
- used to optimize the server and the connections.

-
- This section is used to define client authentications.

-
- <RouterConnection>
-
- This section is used to define the router connections to this
- server/router. Both normal server and router can have router
- connections. Normal server usually has only one connection while
- a router can have multiple. The remote server cannot be older than
- specified Version ID.
