Communication Requirements for Client Agents Installed on UNIX, Linux, and Mainframe Linux Platforms

To help ensure that CA ARCserve Backup primary servers and member servers can communicate with the CA ARCserve Backup agents that are installed on UNIX, Linux, and Mainframe Linux computers, you must allow CA ARCserve Backup to communicate with the agent through the firewall, if any, that is configured on the agent computers. You can allow CA ARCserve Backup to communicate with the agent computers by adding CA ARCserve Backup to the firewall exceptions list on the agent computers.

As a best practice, you should add CA ARCserve Backup to the firewall exceptions list on the agent computers before you install the agents.

This requirement affects the following CA ARCserve Backup components:

• Client Agent for UNIX
• Client Agent for Linux
• Client Agent for Mainframe Linux
• Oracle Agent on UNIX platforms
• Oracle Agent on Linux platforms
• UNIX and Linux Data Mover

For information about how to configure the firewall on the agent computers, see the platform-specific documentation.

Note: By default, CA ARCserve Backup communicates using port 6051.
