- Format:
-
- +<Hash function name>:<SIM path>
-
- <ServerInfo>
-
- 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>
-
- <Identity>
-
- This section is used to set both the user and group which silcd
- sets itself upon starting.
-
- Format:
-
- <user>:<group>
-
- <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>
- +errorlogfile:<path>:<max byte size>
-
- <ConnectionClass>
-
- This section is used to define connection classes. These can be
- used to optimize the server and the connections.
-
- Format:
-
- +<Class number>:<Ping freq>:<Connect freq>:<Max links>
-
- <ClientAuth>
-
- This section is used to define client authentications.
-
- Format:
-
- +<Remote address or name>:<auth method>:<password/cert/key/???>:<Port>:<Class>
-
- <AdminAuth>
-
- This section is used to define the server's administration
- authentications.
-
- Format:
-
- +<Hostname>:<auth method>:<password/cert/key/???>:<Nickname hash>:<Class>
-
- <ServerConnection>
-
- This section is used to define the server connections to this
- server/router. Only routers can have normal server connections.
- Normal servers leave this section epmty. The remote server cannot be
- older than specified Version ID.
-
- Format:
-
- +<Remote address or name>:<auth method>:<password/key/???>:<Port>:<Version ID>:<Class>
-
- <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.
-
- Format:
-
- +<Remote address or name>:<auth method>:<password/key/???>:
- <Port>:<Version ID>:<Class>:<Initiator>
-
- <DenyConnection>
-
- This section is used to deny specific connections to your server. This
- can be used to deny both clients and servers.
-
- Format:
-
- +<Remote address or name or nickname>:<Time interval>:<Comment>:<Port>
-
- <RedirectClient>
-
- This section is used to set the alternate servers that clients will be
- redirected to when our server is full.
