Configuring Domino for IPv6 addressing on Linux™

Before an HCL® Sametime® server can support IPv6 addressing on HCL® Linux™ you must configure IPv6 support for the Domino® server on which it is hosted.

Before you begin

Domino and the Sametime Community server must be installed; the Domino server must be running (it does not matter whether the community server is also running at this point).

About this task

In Domino, only IPv4 addressing is enabled by default. Configuring Domino to support IPv6 involves modifying the Sametime community server's "Server" document within the Domino Administrator interface, as well as adding configuration settings to the notes.ini file used by Domino.

For information on supporting IPv6 with Domino, see "IPv6 and Domino" in the Domino Administration product documentation at:

Domino Administration product documentation

Procedure

To support both IPv4 and IPv6 addressing, update the "Server" document for the community server so that both formats will be accepted:
Note: If you will only support IPv6 addressing, skip this step.
1. On the Sametime Community Server, start the Domino Administrator client.
2. In the Domino Administrator, navigate to the Server pane and double-click your community server's name to select it.
  This opens the corresponding "Server" document.
3. In the "Server" document, navigate to the Internet Protocols > HTTP tab.
4. Update the HTTP hostname field by entering the community server's fully qualified host name, followed by the explicit IPv4 and IPv6 IP addresses for this server.
  Attention: When you fill out this field, you must enter the values using the following format:
  - The first value in the field must a fully qualified host name (for example: commsvr1.example.com).
  - The second and third values must be the explicit IP addresses (using IPv4 dot notation or IPv6 colon notation) that correspond to that host name; the order of these two IP addresses does not matter.
  - Separate values with a carriage return by pressing the ENTER key before adding another value.
5. Save and close the "Server" document.
6. Restart the HTTP service on the Domino server by running the following command in the console:
  tell http restart
Enable support for IPv6 addresses by adding the following setting to the notes.ini file, located in the Domino server data directory:
```
tcp_enableipv6=1
DONT_USE_REMEMBERED_ADDRESSES=1
```
Leave this file open for the next step.
(AIX® only) Add the following setting to the notes.ini file to define the default zone for your server:
```
tcp_defaultzone=zone
```
In this statement, zone is the default zone; this information can be obtained by running the ifconfig -a command.
Restart the Domino server so your changes can take effect.
