How to use IPv6 networking in Wowza Media Server

Wowza Media Server supports IPv6 by default; however, the computer that Wowza Media Server is installed on must also support IPV6, and Java JDK 1.7 is required.

Steps:

1. Test to see if the computer supports IPv6:
   
   
   1. On Windows, open a command prompt window and type the following at the command prompt (Note that "::1" is the IPv6 version of "127.0.0.1" or "localhost"):
      
      Code:

      ping ::1

      Expected output:
      
      Reply from ::1: time<1ms
      Reply from ::1: time<1ms
      Reply from ::1: time<1ms
      Reply from ::1: time<1ms
   2. On Linux, test in the SSH console:
      
      Code:

      cat /proc/net/if_inet6

      Expected output:
      
      fe80000000000000103139fffx8320x4 02 40 20 80 eth0
      00000000000000000000000000000001 01 80 10 80 lo
   
   
2. If the computersupports IPv6, install Java JDK 1.7, then update the java_home environment variable to point to the Java 1.7 JRE. For example, I have:
   
   Code:

   C:\Program Files\Java\jdk1.7.0\jre

   Start Wowza Media Server in standalone mode (/bin/startup.bat or startup.sh) and check the startup lines to see if JDK 1.7 is in use. You should see information similar to the following:
   
   
   INFO server comment - Java Version: 1.7.0-ea
   INFO server comment - Java VM Version: 21.0-b12
   INFO server comment - Java Spec Version: 1.7
   INFO server comment - Java Home: C:\Program Files\Java\jdk1.7.0\jre
3. Ensure that that the following line in /bin/setenv.bat (or setenv.sh) is set to false:
   
   Windows:
   
   Code:

   set JAVA_OPTS=%JAVA_OPTS% -Djava.net.preferIPv4Stack=false

   Linux:
   
   Code:

   JAVA_OPTS="$JAVA_OPTS -Djava.net.preferIPv4Stack=false"

   Also, if running on Windows, open the bin/WowzaMediaServer-Service.conf file in a text editor and add (or modify) the following wrapper.java.additional value:
   
   Code:

   wrapper.java.additional.[n]=-Djava.net.preferIPv4Stack=false

   Where [n] is the next index in the list of wrapper.java.additional items that aren't commented-out.

Now you can test. Use the [install-dir]/examples/SimpleVideoStreaming (Wowza Media Server 3.1.2) or [install-dir]/examples/VideoOnDemandStreaming/FlashRTMPPlayer (Wowza Media Server 3.5 or later) examples and enter the following information in the example player webpage:
Note The square brackets surrounding the IPV6 address.

You can get the IPV6 address of your remote server with the ipconfig command in Windows, or the ifconfig command in Linux.
