Enabling IPv6 addressing for a Community Server on Linux SuSE

By default, support for IPv6 addressing is disabled in the version of IBM® Sametime® that runs on Linux® SuSE operating systems; you must enable IPv6 support in the "ststart" script used by Sametime on a Linux SuSE server.

Before you begin

Previous releases of Sametime did not support IPv6 addressing. Because the Linux SuSE operating system already supported IPv6 by default, it was necessary to specifically disable IPv6 for Sametime on those servers. If you want to support the use of IPv6 addresses with Sametime on a Linux SuSE server, you must re-enable support for IPv6 by modifying the ststart script.

Note: This task is needed only for Linux SuSE servers.

Procedure

  1. On the Community Server, open a command window and navigate to the Sametime data directory (for example, /local/notesdata).
  2. Open the ststart script so you can edit it.
  3. Comment out the following statements by inserting the # character at the beginning of each line:
    	if [ -f /etc/SuSE-release ]; then
	       IBM_JAVA_OPTIONS=-Djava.net.preferIPv4Stack=true
	       export IBM_JAVA_OPTIONS
	fi

    The statements should now look like this:

    	#if [ -f /etc/SuSE-release ]; then
	#      IBM_JAVA_OPTIONS=-Djava.net.preferIPv4Stack=true
	#     export IBM_JAVA_OPTIONS
	#fi
  4. Save and close the file.
  5. Stop and restart the Sametime Community Server.
