Configuring X.32 Authentication Procedures

Next you need to configure the X.32 authentication procedures. These are used on dial-up links by most PSDNs, to prevent people without permission from dialing in. To configure X.32 authentication:

1. Set Enable X.32 Authentication to Yes.

   You can choose to carry out X.32 authentication at link level or a packet level. When connecting to a PSDN, use link level as this means the authentication is carried out by the network. Packet level is appropriate when connecting with another machine (back to back, for example) when you want the machine and not the network to do the authentication. Both the Identity and the Signature can be any hexadecimal string, up to 32 characters long, not containing whitespace.

2. Click on OK to exit the LAPB and WAN parameters window.

3. Save the configuration.

   This makes sure your changes will be used when you start X.25. From the x25tool main menu select File => Save, and save the changes to the current configuration. Or you can select File => Save As, to save the changes in a different configuration.
