Configuring an endpoint for automatic or manual dialup

In these types of outgoing link endpoints, the remote host can set one or both of the IP addresses used at both ends of the link.

The following information is needed to configure an endpoint:

Remote system

The name of the remote system. (This name is used to create or amend an entry in the UUCP Systems file. It does not need to be identical to the hostname of the remote system.)

Phone number

The telephone number of the remote system.

Authentication

When making a dialup connection, your system will normally need to authenticate itself with the remote system using a login script and/or an authentication protocol.

Select Simple login script if the remote system expects you to authenticate yourself using a login name and password. To edit the login script (also known as a chat script), click on Edit script. On the Edit Login Script screen, replace the identifiers $LOGIN and $PASSWORD in the displayed list of Send strings with your login name and password.

To add a pair of Expect and Send strings:

1. Select an existing pair from the list to which the new pair will be adjacent, and click on Add.

2. On the Add Expect/Send pair screen, enter the new strings, and select whether the new pair should be placed before or after the highlighted entry. If no entry is highlighted, the new pair will be placed at the end of the list.

3. Click on OK.

To modify a pair of Expect and Send strings:

1. Select the pair to be modified from the list, and click on Modify.

2. On the Modify Expect/Send pair screen, edit the strings as necessary.

3. Click on OK.

To delete a pair of Expect and Send strings:

1. Select the pair to be deleted from the list, and click on Delete.

Click on OK when you have finished editing the login script.

For more information about creating login scripts see ``Adding entries for remote sites to the Systems file'' in the System Administration Guide.

Select one of CHAP or PAP


if the remote system uses the Challenge-Handshake Authentication Protocol (CHAP) or the Password Authentication Protocol (PAP) to authenticate your system:

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

2. On the CHAP/PAP Authentication Options screen, enter the ID and password that are needed to authenticate your system. The ID indicates the entry to be used from the /etc/pppauth file for local host ID lookups. The ID and password is 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.

---

NOTE: Do not select either CHAP or PAP if the remote system does not require either of these authentication methods to be performed.

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 without the link being present.

Leave this field blank or set it to ``0.0.0.0'' if the remote system will assign the local IP address.

You can change how IP addresses are negotiated using the IP advanced options. See ``Configuring IP parameters'' for details.

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.

Leave this field blank or set it to ``0.0.0.0'' if the remote system will assign the remote IP address.

You can change how IP addresses are negotiated using the IP advanced options. See ``Configuring IP parameters'' for details.

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'' in Configuring Network Connections.

Attach name

---

NOTE: This field is only displayed if you are configuring a manual dialup endpoint.

---

A unique name for the endpoint configuration that can be used with the pppattach(ADMN) command to establish a link.

See ``Example entry for automatic dialup'' and ``Example entry for manual dialup'' for example entries in the /etc/ppphosts file for these types of configuration.

See ``How UUCP is configured for outgoing dialup'' for more information about how links established from automatic and manual dialup endpoints use UUCP to make outgoing connections.
