IBM Lotus Sametime 7.5.1 Release Notes
Services.
After you have added a new IP address to the Sametime server, set up your DNS server to map the new
IP address to a DNS name for the Sametime server Community Services.
For the Community Services, map the IP address to the DNS name "community-xxx.xxx.xxx" (where
xxx.xxx.xxx is the DNS name that was bound to the Sametime HTTP server in step 1 above).
For example, you would map the new IP address to the DNS name "community-www.sametime1.com."
Step 4 - Configure the HTTPS-tunneling settings in the Sametime Administration Tool
You must specify the new DNS name and port number for Community Services HTTPS connections in
the Sametime Administration Tool.
1.
Open the Sametime Administration Tool and select Configuration-Connectivity-Networks and Ports.
2.
In the Community Services Network-Address for HTTPS-tunneled connections settings, specify the
following:
Host name: community-xxx.xxx.xxx (Where xxx.xxx.xxx is the DNS name that was bound to the
Sametime HTTP server. For example, community-www.sametime1.com.)
Port number: 443
With this configuration, the Sametime Community Services multiplexer will listen for HTTPS-tunneled
connections on host name community-www.sametime1.com on port 443.
Step 5 - Configure the Sametime Connect clients to connect to the new DNS name of the Community
Services
To connect to a Sametime server configured to listen for HTTPS connections on the host name and port
specified above, the Sametime Connect client must have the following settings in the Sametime
Connectivity tab:
z
The "Host" setting must specify community-www.sametime1.com.
Note If a Sametime 2.5 Connect client connects to a Sametime 7.5.x server using HTTPS on port 443
or 563, it is only necessary to enter the server name (www.sametime1.com) in the "Host" setting of
the Sametime 2.5 Connect client. For example, enter "www.sametime1.com" instead of
"community-www.sametime1.com" in the "Host" field. For more information, see "Sametime 2.5
Connect client compatibility issue when connecting to a Sametime 7.5.x server on port 443 or 563"
below.
z
The "Community port" setting must specify 443.
z
"Use proxy" and "Use HTTPS proxy" must be selected. Enter the host name and port on which the
Sametime Connect client connects to the HTTPS proxy.
Sametime 2.5 Connect client compatibility issue when connecting to a Sametime 7.5.x server on port
443 or 563
The Sametime 2.5 Connect client is designed to use HTTPS tunneling on ports 443 or 563 to connect to a
server that uses multiple IP addresses.
When a Sametime 2.5 server is configured to listen for HTTPS-tunneled client connections on port 443 or
563, the server listens for Community Services connections on the server name
"Community-servername." For example, if your Sametime 2.5 server is named
sametimeserver.acme.com, the server listens for HTTPS-tunneled Community Services connections on
ports 443 or 563 on the server name "Community-sametimeserver.acme.com." The Sametime 2.5 server
is hard-coded to prepend the string "Community-" to its server name when listening for Community
