Configuring an endpoint for a dedicated link

This type of endpoint uses a dedicated serial line over which a dedicated link can be established to a similar endpoint on another system.

The following information is used to configure an entry for the endpoint in the /etc/ppphosts file:

Serial port

The name of the serial port device used by this endpoint. Choose an entry from those listed or click on Add port if you want to define a new serial card and the ports it controls. See ``Adding and configuring serial cards'' for details.

Line speed (bps)

The line speed for the designated serial line, in bits per second. Choose a speed from the point-and-pick list. The default value is 38400.

Local address

The IP address or the host name for the local end of the PPP link. The remote system must agree to use the specified address or the local system will refuse to establish the link.

If a host name is entered, it is saved in /etc/ppphosts rather than the corresponding IP address. The name must be resolvable using DNS or an entry in the /etc/hosts file.

The remote system may ignore this address if it is configured to assign it.

Remote address

The IP address or the host name for the system at the remote end of the PPP link. The remote system must agree to use the specified address or the local system will refuse to establish the link.

If a host name is entered, it is saved in /etc/ppphosts rather than the corresponding IP address. The name must be resolvable using DNS or an entry in the /etc/hosts file.

The remote system may ignore this address if it is configured to assign it.

Netmask

The netmask to use over a link connected to this endpoint. The netmask must match that used by the remote system. For more information on netmasks, see ``Netmask setting''.

Authentication

If required by the remote system, you can use one of the Challenge-Handshake Authentication Protocol (CHAP), the Microsoft extension to the CHAP protocol (MSCHAP) or the Password Authentication Protocol (PAP) to authenticate your system:

1. Select the authentication method to be used and click on Configure.

2. On the CHAP/MSCHAP/PAP Authentication Options screen, enter the ID and password that are needed to authenticate this system. The ID indicates the entry to be used from the /etc/pppauth file for local host ID lookups. The ID and password are optional, provided there is a default entry in the /etc/pppauth file.

   You can also change the time period in minutes within which the authentication must be performed. The default value is one minute.

3. Click on OK when you have finished entering the details needed to authenticate your system.

See ``Example entry for a dedicated serial endpoint'' for an example entry in the /etc/ppphosts file for this type of configuration.
