Security Considerations

In order to strengthen system security, it is recommended that you turn off the Remote

Procedure Calls (RPC) service on all Linux servers that run Avaya Integrated Management

applications. To turn off the RPC service, you must close all related ports that provide the

service.

Note:

Note: You must have root access to turn off the RPC service.

Perform the following steps:

1. To turn off the service, at the command line prompt in the terminal emulation window, type

service portmap stop.

2. To turn off the service so that it does not start again when the Linux server is restarted, at

the command line prompt in the terminal emulation window, type

chkconfig -levels 12345 portmap off.
