* sl_relay [#k8b98ddc] [[日本語はこちら>sl_relay]]~ ** Outline [#uf81341b] -''sl_relay'' is a Packet Relay Server for Second Life running on Linux. It is aimed at connecting to Second Life Servers from a PC through a firewall such as might be found in a university. -''sl_relay'' relays communication (UDP,HTTP/HTTPS) between the SIM Server and the Second Life viewer. - Note: it not only relays but also scans inside each packet. Thus when the content of a packet (URL, IP address and port number) indicate another SIM is involved, a new relay process for that SIM can be started. - ''[[sl_cache>sl_cache (E)]]'' can be used with ''sl_relay'' to provide a texture data cache. - When caching UDP packets (''[[sl_cache>sl_cache (E)]]''), the sequence number of each UDP packet is rewritten to prevent contradictions. - It is also possible to limit access to particular SIMs by using ''sl_relay'' with the Information Server (''[[sl_info>sl_info (E)]]''). - ''sl_relay'' is part of ''[[sl_proxy>sl_proxy (E)]]''. - The current version is ''1.10.0'' (29 Step. '11) #br ***''Outline of Functions.'' [#b28df040] + You can execute Second Life from a PC with private IP address behind a firewall. + You can specifiy the port number for firewall access. + Access to ''sl_relay'' can be controlled. + Full HTTPS access between Viewer and Relay Server is possible. (default is HTTP) + MusicURL and MediaURL(High 23) is supported. However, it is recommended that a Web proxy be used. + External Web Proxy (e.g. squid) connection is supported. Moreover, an internal Web Proxy function is included. + [[OpenSim]] is supported. (Test version) + ''[[sl_cache>sl_cache (E)]]'' connection is supported. (''[[sl_cache>sl_cache (E)]]'' is the texture cache server for ''sl_relay''.) + When ''[[sl_cache>sl_cache (E)]]'' is down or response is too slow, ''sl_relay'' automatically disconnects from the cache server after short delay. + Access to Second Life SIMs can be controlled, by Avatar, viewer machine IP or at the global SIM level through the use of white lists with ''[[sl_info>sl_info (E)]]''. ***''Annoyances or Bugs.'' [#dc53166d] + You might see the same message two or more times in IM or chat. The cause is unknown, sorry. + A stress test of ''sl_relay'' has not been carried out. **''Explanation'' [#g7f1e55f] + [[Over the Firewall>./Firewall]] + [[Cooperation with the Cache Server>./Cooperation with the Cache Server]] + [[Cooperation with the Information Server>./Cooperation with the Information Server]] + [[Communication by HTTPS>./Communication by HTTPS]] + [[WEB Proxy Function>./WebProxy]] + [[When the server has two or more network interfaces>/sl_proxy (E)/two or more network interfaces]] + [[Rewrite Viewer Version>./Rewrite Viewer Version]] + [[Log and Debug Mode>./Log and Debug Mode]] + [[Security>./Security]] + [[Get Grid Information>./Get Grid Information]] ** Configuration [#q6718feb] - The default configuration file is ''/usr/local/etc/sl_proxy/sl_relay.conf''. - It is also possible to specify an alternate configuration file using the ''-f'' option of ''sl_relay''. - Because the configuration file is read before ''sl_relay'' 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. #br *** Items [#mdd29c33] **** Communication port with SIM Server [#p93e3cae] -[[MinUdpExPort>./MinUdpExPort]] -[[MaxUdpExPort>./MaxUdpExPort]] -[[MinTcpExPort>./MinTcpExPort]] -[[MaxTcpExPort>./MaxTcpExPort]] **** Communication port with Viewer [#k3e77800] -[[MinUdpImPort>./MinUdpImPort]] -[[MaxUdpImPort>./MaxUdpImPort]] -[[MinTcpImPort>./MinTcpImPort]] -[[MaxTcpImPort>./MaxTcpImPort]] **** Control port of Relay Controller [#veb796bb] -[[MinControlPort>./MinControlPort]] -[[MaxControlPort>./MaxControlPort]] **** HTTPS(SSL) [#c3106ca2] -[[CERT_PEM_File>./CERT_PEM_File]] -[[SKEY_PEM_File>./SKEY_PEM_File]] -[[CA_PEM_File>./CA_PEM_File]] **** Access control [#rf8a9f3c] -[[Hosts_Allow_File>/sl_proxy (E)/Hosts_Allow_File]] -[[ExternalWebProxy>./ExternalWebProxy]] -[[Proxy_Allow_File>./Proxy_Allow_File]] **** Etc. etc. [#s663b4ba] - [[SL_GridInfo_File>/sl_proxy (E)/SL_GridInfo_File]] - [[Temp_File_Dir>/sl_proxy (E)/Temp_File_Dir]] - [[MaxIdleTime>/sl_proxy (E)/MaxIdleTime]] #br **Execute Options [#p28613aa] sl_relay [-s server_name[:port]] [-p port] [-f config_file] [-u user_name] [-i interface_address] [-pid pid_file] [-l [log_file]] [-v syslog_level] [-cs [cache_server:port]] [-cg] [-cp] [-is [info_server:port]] [-wf] [-vs [voice_relay_server:port]] [-as] [-aca] [-ano] [-xp [web_proxy_server:porti]] [-ip [port]] [-ipx [port]] [-mm] [-ver version] [-d] [-x] [-xt] [-xu] [-xuf] [--version] [--help] [-h] -s : specify login server of Second Life. default is login.agni.lindenlab.com:443 -p : port number that Viewer connects. default is 8100. -f : configuration file. default is /usr/local/etc/sl_proxy/sl_relay.conf -u : specify effective user. -i : specify Viewer side network interface IP address. if your server has two or more network interfaces, you need to use this option. -pid : specify pid file. -l : specify log file. default is /var/sl_proxy/sl_relay.log -v : level of syslog. default is LOG_INFO (7). -cs : specify sl_cache cache server. default is localhost:8200 -cg : only get cache data. do not save data. -cp : only save cache data. do not get data. -is : specify sl_info infomation server. default is localhost:8086 -wf : The access limitation to SIM by the white list is done in cooperation with sl_info. -vs : specify sl_voice_relay server. default is localhost:8088 -as : use HTTPS between Viewer and Relay Server. -aca : confirms Second Life Server by using C:\Program Files\SecondLife\app_settings\CA.pem -ano : no HTTPS communication. Do not use, usually. It is for OpenSim olny. (Experimental option) -xp : specify external web proxy server. -ip : use internal web proxy function with full access mode. excute internal web proxy process. port number can be specified. -ipx : use internal web proxy function with restricted mode. excute internal web proxy process. port number can be specified. -mm : relay MusicURL and MediaURL(High 23). If it is possible, to use web proxy function of viewer. -ver : rewrite Viewer version. Please use this temporarily only when you cannot immediately install new Viewer. It is dangerous to use this lasting long, and never do it!! -d : debug mode. display debug information -x : TCP(HTTP/HTTPS) packets are saved at working directory and UDP packet headers are printed. -xt : TCP(HTTP/HTTPS) packets are saved at working directory. -xu : UDP packet headers are printed. -xuf : UDP packet is full dumped. --version : display Version information. --help, -h : display this Help messages. **Processes [#f13647f7] ***Relationship between Processes [#ece449c6] http://www.nsl.tuis.ac.jp/xoops/modules/xpwiki/?plugin=ref&page=sl_relay&src=sl_relay.png ***Transformation of UDP and HTTP/HTTPS Packets [#cfd53c48] http://www.nsl.tuis.ac.jp/xoops/modules/xpwiki/?plugin=ref&page=sl_relay&src=sl_relay2.png -[Proxy Process] is ''Relay Process'' -[Control Process] is ''Relay Controller''
