Chapter 4    Setting Up RACs

Managing Remote Access Concentrators Using Annex Manager

The

PPP Security Protocol

 box defines the security check that the RAC

requires before it starts the network control protocol. You can select:

•

 None

•

Pap

 - to use password authentication protocol

•

Chap

 - to use challenge-handshake protocol

•

Chap/Pap -

to request the challenge handshake protocol or

to request password authentication if the peer rejects

Chap

The

Outgoing

 box activates security for outgoing modem and non-modem

ports, and for WAN calls.

The

On

 and

Off

 buttons control host-based security for access through the

port server. If you select the

On

 button only authorized users have access

to the ports.

The

 Host Access

 box provides

Restrict

 buttons. The

On

 and

Off

 buttons for

the

Restrict

 field activate host-based security that authorizes connections

from CLI to a network host. If you select the

On

 button, the security server

authorizes a connection based on the

acp_restrict

 file.

The

VCLI

 box provides the

Security

 buttons.

 The

On

 and

Off

 buttons for the Security field control user validation on

virtual CLI connections to a RAC. If you select the

On

 button the RAC

uses the same user name and password validation for virtual CLI
connections as it does for CLI security.
