Problems with PPP Negotiation

Once you have a modem connection, the next step in the connection phase is the PPP negotiation. The client and the server communicate to negotiate a common configuration for the PPP link. The policy is to converge if at all possible; however, failure to agree on certain mandatory parameters will cause the negotiation to fail.

The following log file extract was generated when the PPP negotiation failed:

11/13/95 20:34:42 - Connection requested to miles
11/13/95 20:34:43 - Dialing number P365 ...
11/13/95 20:35:16 - Got modem connection
11/13/95 20:35:19 - LCP up on ipdptp0
11/13/95 20:35:19 - PPP error on ipdptp0: Negotiation of mandatory
options failed

In this example, the error was provoked by an IP address that did not match the IP address expected by the server. If the PPP negotiation fails, check your configuration against the information that your system administrator or Internet provider gave you. If it is correct, contact your system administrator or Internet provider for help, as they may need to modify the server configuration.
