Servers Configuration

Master Server

Icecast version: Icecast 2.3.2-kh4-giss from G.I.S.S. cvs :

export CVSROOT=:pserver:anonymous@giss.tv:/home/cvs
cvs co icecast-2.3.2-kh4-giss

this version is based on Icecast 2.3.2-kh4 from : http://www.xiphicecast.webspace.virginmedia.com but it is only for the master server!

In master server we use an standard icecast.xml conf adding only this line:

<max-redirect-slaves>10</max-redirect-slaves>

Relay Servers

Icecast version: Icecast 2.3.2-kh20a from http://www.xiphicecast.webspace.virginmedia.com

You need to build icecast with libvorbis-dev + libogg-dev + libtheora-dev + libcurl-dev

tar xvfz icecast-2.3.2-kh20a.tar.gz
cd icecast-2.3.2-kh20a/
./configure --with-ogg --with-vorbis --with-theora --with-curl
make 
make install

With this conf each relay server only get one stream till master redirects a client to it.

In each relay server we use an standard icecast.xml conf adding this lines:

<master-server>giss.tv</master-server>
<master-server-port>8000</master-server-port>
<master-update-interval>10</master-update-interval>
<master-password>PASSWORDRELAY</master-password>
<master-relay-auth>1</master-relay-auth>
<master-redirect-port>8000</master-redirect-port>
<master-redirect>1</master-redirect>
<relays-on-demand>1</relays-on-demand>

and changing this parameters:

<clients>160</clients>
<sources>50</sources>

the <clients> value depends on your network bandwidth. So aprox:

for 20 mbps bandwidth, to use 160 as max clients is a good choice
for 50 mbps bandwidth, 400
for 100 mbps bandwidth, 800

the same with <sources>

To request the PASSWORDRELAY to add a new relay server, please send a mail to the GISS admins : gissnetwork _(at)_ gmail _(dot)_ com.
