Outline†[edit]

• sl_proxy is a Proxy System for Second Life/OpenSim.
• This system consists of a Packet Relay Server(sl_relay) , a Texture Cache Server(sl_cache), an Information Server(sl_info) and a Voice Chat Realy System(sl_voice_relay) all running on Linux.
• So, sl_proxy = sl_relay + sl_cache + sl_info + sl_voice_relay.

• sl_relay relays UDP/HTTP(S) packets to a Second Life SIM Server.
• sl_cache caches UDP Texture data from a SIM Server. (But, sl_cache seems to be useless since SL Viwer 2.1.1. So SL Viewer use "HTTP Get Texture" since v2.1.1)
• sl_info gathers agents and SIMs infomation from sl_relay. It is also possible to limit access to inappropriate or undesirable SIMs through the use of a white list.
• sl_voice_relay relay the vivox's SIP, RTP and RTCP packets for voice chat.

• You can run a Second Life viewer from a PC with private IP address behind a firewall.

• sl_proxy was made to be used in public organizations such as Universities.
• Its use is free for educational institutions (free for non-commercial use).

• Current version is 1.10.4 (30 July. '12).

• Note: sl_proxy is not GridProxy (this old name is SLProxy)

sl_relay†[edit]

• sl_relay is a Relay Server for Second Life. It relays UDP/HTTP(S) packets to a Second Life SIM Server.
• For more information please see sl_relay.

sl_cache†[edit]

• sl_cache is a Texture Cache Server for Second Life.
• For more information please see sl_cache.

sl_info†[edit]

• sl_info is an Information Server.
• sl_info gathers agents and SIM infomation from sl_relay. It is used to monitor usage of sl_relay.
• sl_info is also used to provide the white list of SIMs.
• For more information please see sl_info.

sl_voice_relay†[edit]

• sl_voice_relay relays the packets of the SIP system of the Vivox, and enables to use of the voice chat of Second Life for PC in the firewall.
• For more information please see sl_voice_relay.

• Thanks to kittin

Compile and Install†[edit]

• This software needs the development environments for OpenSSL, zlib and (optionally) Berkeley DB (4.2).
• If necessary please install them before proceeding.
• The --enable-db option enables the use of Berkeley DB and can be omitted.

# zcat sl_proxy-X.Y.Z.tar.gz|tar xfv -
# cd JunkBox_Lib
# ./configure  --enable-db
# make
# cd ../sl_proxy-X.Y.Z
# ./configure  --enable-db
# make
# make install

• If you use Gentoo Linux, please read "Install to Gentoo Linux Documention" by Uwe. Original File: README_on_gentoo

Execution and Stop†[edit]

Running sl_proxy†[edit]

• Execution

  # /etc/init.d/sl_voice_relay start
  # /etc/init.d/sl_info start
  # /etc/init.d/sl_cache start
  # /etc/init.d/sl_relay start

• Monitoring of Users

  # tail -f /var/sl_proxy/sl_info_agent.log

• Stop

  # /etc/init.d/sl_relay stop
  # /etc/init.d/sl_cache stop
  # /etc/init.d/sl_info stop
  # /etc/init.d/sl_voice_relay stop

SL Viewer (MS Windows) Setting†[edit]

• add exec option.... --loginuri http://FQDN:8100/cgi-bin/login.cgi

  > SecondLife.exe --loginuri http://FQDN:8100/cgi-bin/login.cgi

• FQDN is proxy server's FQDN or IP address. 8100 is port number the Viewer connects to.(-p option)
• Changes are made by editing the Target filed of the Second Life shortcut icon.
