Deploying
IBM® Sametime® consists of a variety of servers and clients, and can be deployed to suit many different environments. The deployment instructions are organized by feature set, beginning with the minimum components that are necessary to support instant messaging, and then expanding the deployment to include features such as audio and video support, and conferencing.
Deploying instant messaging
Instant messaging features are provided primarily by the IBM® Sametime® Community Server, which supports presence, text chats, and two-way phone calls.
Securing the Sametime® Community Server
The IBM® Sametime® server uses the Internet and intranet security features of the Domino® server on which it is installed to authenticate web browser users who access Domino databases on the server.
Configuring Sametime® Community Server to use SSL encryption
Configure IBM® Sametime® Community Server to use SSL (Secure Socket Layer) for its services; and configure HTTPS when communicating with Web clients or enable LDAPS (LDAP over SSL) with the LDAP server.
Enabling encryption between a Sametime® Community Server and the LDAP server
Configure SSL encryption between an IBM® Sametime® Community Server and an LDAP server by enabling the LDAPS protocol.
Installing GSKit on the Sametime® Community Server

About this task

IBM® Domino® ships with a version of GSKit, but for this task you must use the version included with IBM Sametime® Community Server.

To install GSKit on Linux, follow the steps:

Procedure

Log on to the server as the root user.
Stop the IBM Domino and Sametime server.
Expand the GSKit package into a temporary directory.
Install GSKit to the relevant operating system, 64-bit, as follows:
1. Change to the temporary directory where you expanded the GSKit package.
2. Install the packages into the usr/lib directory by using the following command:
```
rpm -Uv --prefix /usr/lib gskcrypt32-version_number.linux.arch.rpm gskssl32-version_number.linux.arch.rpm 
```
  The string version_number represents the version number of GSKit being installed, such as 8.0.14.6, and can vary as new modifications of GSKit are released.
  The string arch represents your system architecture, for example x86.
