IBM Lotus Sametime 7.5 Release Notes Installation, migration, upgrade, and configuration
With these configurations, the Sametime Connect client connects to the HTTPS proxy, and the proxy
connects to the Sametime server on behalf of the Sametime Connect client. The connection from the
proxy server to the Sametime server Community Services occurs on port 443. The Community Services
on the Sametime server must be configured to listen for the HTTPS connections on port 443 to ensure the
connection can succeed.
Note The configurations above enable Sametime Connect to establish a connection to a Sametime server
through an HTTPS proxy server. The HTTPS connection method is used to establish the connection but
the data passing over this connection is not encrypted with SSL.
If the Domino HTTP server is also configured to listen for HTTPS connections on port 443, a conflict
occurs because the Sametime Community Services are also configured to listen for HTTPS connections
on the same port number.
In this scenario, you must assign an additional IP address to the Sametime server to ensure that both
Web browser users and Sametime Connect client users can connect to the Sametime server on port 443.
This configuration requires the following steps:
z
Bind the DNS name for the Sametime server to the Sametime HTTP server.
z
Add a new IP address to the Sametime server machine.
z
Map the new IP address to a new DNS name for the Sametime Community Services. This
configuration is performed on the DNS server.
z
Use the Sametime Administration Tool to add the new DNS name to the Community Services
connectivity settings on the Sametime server. This configuration enables the Community Services to
listen for HTTPS connections on the new DNS name.
z
Configure the Sametime Connect clients to connect to the new Community Services DNS name.
Note The configuration described below can enable either a Sametime 2.5 (or higher) Connect client to
connect to a Sametime 7.5 server on port 443 or 563.
Step-by-step instructions for these configurations are provided below.
Step 1 - Bind the base DNS name for the Sametime server to the Sametime HTTP server .
1.
Open the Sametime Administration Tool and select Configuration-Connectivity-Networks and
Ports-Configure HTTP services on a Web page in its own window. The HTTP section of the Server
document in the Domino Directory opens and displays in a separate window on the computer.
2.
Under the Basics heading in the "Host name" field, enter the base DNS name for the Sametime HTTP
server (for example, www.sametime1.com).
Under the Basics heading In the "Host name" field, also enter 127.0.0.1. This entry is required for the
Sametime Administration Tool to operate in this configuration. Place a comma between the DNS
name of the HTTP server and the 127.0.0.1 entry (e.g. www.sametime1.acme, 127.0.0.1)
3.
Click "Save & Close" at the top of the Server document. After the document closes, close the
Server-Servers view of the Domino Directory.
