UNIX, Linux, and Mac OS X Client Agent Configuration The following sample shows the configuration file before and after the script changes are made. Before the change: [36] #[ABcmagt] #NAME #HOME #TCP_PORT #UDP_PORT ABcmagt /opt/CA/ABcmagt 6051 6051 After the change: [36] #[ABcmagt] NAME HOME TCP_PORT UDP_PORT ABcmagt /opt/CA/ABcmagt 9051 9051 The port changes take effect only after you restart the Common Agent. If you configure the Common Agent to run on a port other than the default port, you should also configure the CA ARCserve Backup server to access this Common Agent. You can do this by making an entry for the client agent in the port.cfg file. This file is in the config subdirectory under the home directory- $BAB_HOME/config/port.cfg-on the backup server. By default, the Common Agent uses another UDP port, 0xA234 (41524), to receive CA ARCserve Backup requests for the Auto Discovery of UNIX, Linux, and Mac OS X client agents. This port is not configurable. Host Equivalence User Credentials When the Common Agent checks user credentials, it gives preference to host equivalence settings of the system. A UNIX, Linux, or Mac OS X system can be set up to grant access for specific users on specific hosts without requiring the user to provide credentials. You can grant this access by adding the specific user IDs to the /etc/hosts.equiv or .rhosts file. By default, the Common Agent follows these rules, then checks the user's password for authorization. To disable host equivalence checking, define the NO_HOSTS_EQUIV=1 environment variable in the agent.cfg file, as shown in the following example: Chapter 3: Adding and Configuring the Client Agents 41

UNIX, Linux, and Mac OS X Client Agent Configuration
Chapter 3: Adding and Configuring the Client Agents
41
The following sample shows the configuration file before and after the script
changes are made.
Before the change:
[36]
#[ABcmagt]
#NAME
ABcmagt
#HOME
/opt/CA/ABcmagt
#TCP_PORT
6051
#UDP_PORT
6051
After the change:
[36]
#[ABcmagt]
NAME
ABcmagt
HOME
/opt/CA/ABcmagt
TCP_PORT
9051
UDP_PORT
9051
The port changes take effect only after you restart the Common Agent. If you
configure the Common Agent to run on a port other than the default port, you
should also configure the CA ARCserve Backup server to access this Common
Agent. You can do this by making an entry for the client agent in the port.cfg file.
This file is in the config subdirectory under the home directory
$BAB_HOME/config/port.cfg
on the backup server.
By default, the Common Agent uses another UDP port, 0xA234 (41524), to
receive CA ARCserve Backup requests for the Auto Discovery of UNIX, Linux, and
Mac OS X client agents. This port is not configurable.
Host Equivalence User Credentials
When the Common Agent checks user credentials, it gives preference to host
equivalence settings of the system. A UNIX, Linux, or Mac OS X system can be
set up to grant access for specific users on specific hosts without requiring the
user to provide credentials. You can grant this access by adding the specific user
IDs to the /etc/hosts.equiv or .rhosts file. By default, the Common Agent follows
these rules, then checks the user’s password for authorization. To disable host
equivalence checking, define the NO_HOSTS_EQUIV=1 environment variable in
the agent.cfg file, as shown in the following example:
