sl_info†[edit]

Outline†[edit]

• sl_info is an Information Server for Second Life and is used with sl_relay.
• sl_info collects information on users (avatars) and SIMs through sl_relay.
• The accessibility of specific SIMs through sl_relay 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 if access is permitted.

• sl_info is part of sl_proxy.
• Current version is 1.1.0 (28 Step. '11)

Function Outline†[edit]

1. The status of Relay Server (sl_relay) can be monitored.
2. Information on SIMs can be collected via relay server (sl_relay).
3. It notifies Relay Server (sl_relay) whether a particular SIM should be accessible according to the rules of the white list.

Annoyances and Bugs.†[edit]

1. Information is saved in a plain file or a Berkeley DB file. SQL databases are not supported.
2. It is only possible to collect data for a SIM that is listed in the rules of the white list.

Explanation†[edit]

1. Gathering and Tendering of Information
2. White List Filter
3. SIM Data Base
4. How the server operates with two or more network interfaces
5. Log and Debug Mode
6. Security

Configuration†[edit]

• 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.

Items†[edit]

• MinUdpGatherPort
• MaxUdpGatherPort
• MinUdpInfoPort

Execute Options†[edit]

sl_info  [-p port_no] [-f config_file] [-u user_name] [-i interface_address]
         [-pid pid_file] [-l [agent_log]] [-v syslog_level]
         [-fdb] [-wf [white_list]] [-d]
         [--version] [--help] [-h]
       
-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   : specify effective user.
-i   : specify sl_relay side network interface IP address.
       if your server has two network interface and more, you need to use this option.
       
-pid : specify pid file.
-l   : specify log file. default log file is /var/sl_proxy/slcache.log
-v   : level of syslog. default is LOG_INFO (7).
       
-wf  : Information on the white list is offered.
       The access limitation to SIM is done in cooperation with sl_relay.
       
-fdb : Berkeley DB is used for the data base. default is plain file.
-d   : debug mode. display debug information.
       
--version  : display Version information.
--help, -h : display this Help messages.
