[[日本語はこちら>sl_info]]~

** Outline [#uf52edaf]
- ''sl_info'' is an Information Server for Second Life and is used with ''[[sl_relay>sl_relay (E)]]''.
- ''sl_info'' collects information on users (avatars) and SIMs through ''[[sl_relay>sl_relay (E)]]''.
- The accessibility of specific SIMs through ''[[sl_relay>sl_relay (E)]]'' is controlled based on collected information (avatar identity, viewer ip address and SIM name) and referenced to information kept in a white list. ''sl_info'' uses this information to inform ''[[sl_relay>sl_relay (E)]]'' if access is permitted.

- ''sl_info'' is part of ''[[sl_proxy>sl_proxy (E)]]''.
- Current version is ''1.0.0''  (27 July '08)

*** Function Outline [#gd1c99c9]
+The status of Relay Server (''[[sl_relay>sl_relay (E)]]'') can be monitored.
+Information on SIMs can be collected via relay server (''[[sl_relay>sl_relay (E)]]'').
+It notifies Relay Server (''[[sl_relay>sl_relay (E)]]'') whether a particular SIM should be accessible according to the rules of the white list.

***Annoyances and Bugs. [#ie9ebcd0]
+Information is saved in a plain file or a Berkeley DB file. SQL databases are not supported.
+It is only possible to collect data for a SIM that is listed in the rules of the white list.

** Configuration [#tef5ed9b]
-The default configuration file is ''/usr/local/etc/sl_proxy/sl_info.conf''.
-It is also possible to specify an alternate configuration file using the ''-f'' option of ''sl_info''.
-Because the configuration file is read before ''sl_info'' does the switch to the effective user, exec user should be able to be read.
-The setting of each item is described in the configuration file. Empty lines or lines starting with # are not read.

** Execute Options [#nb85999c]
 sl_info   [-p port_no] [-f config_file] [-u user_name] [-pid pid_file] [-i interface_address]
           [-v syslog_level] [-l [agent_log]] [-fl] [-fdb] [-wf [white_list]] [-d]

  -p  : port number that Relay Server(sl_relay) connects. default is 8200.
  -f  : configuration file. default is /usr/local/etc/sl_proxy/sl_cahe.conf
  -u  : effective user.
  -pid: pid file.
  -i  : specify sl_relay side network interface IP address.
        If your server has two network interface and more, you need to use this option.
  -v  : level of syslog. default is LOG_INFO (7).
  -l  : create log file. default log file is /var/sl_proxy/slcache.log
  -fl : Plane file is used for the data base. default.
  -fdb: Berkeley DB is used for the data base.
  -wf : Information on the white list is offered.
        The access limitation to SIM is done in cooperation with sl_relay.
  -d  : debug mode.
