chap_secret
The chap_secret attribute defines the token used for authentication when
you use the CHAP protocol for PPP links. CHAP authenticates users
based on the user names in the acp_userinfo file. To create a token:
1. From the Bay Networks program group window, double-
click on the appropriate icon to open the acp_userinfo file.
The acp_userinfo file opens in the Notepad editor.
2. Find the area of the file where entry information resides and
type
chap_secret
following by the token.
Each token can use up to 32 alphanumeric characters. Bay
Networks recommends that all tokens use at least 16 characters.
Using the acp_keys File
The acp_keys file stores RAC names or IP addresses and corresponding
encryption keys. Erpcd uses the keys you define here to create encryption
keys that the security server and a RAC use to exchange messages. When
the security server receives an encrypted message from a RAC, it matches
the key with an associated RAC in the acp_keys file. If there is no match,
the RAC and the server cannot communicate.
To create an entry in the acp_keys file:
1. From the Bay Networks program group window, double-
click on the appropriate icon to open the acp_keys file.
The acp_keys file opens in the Notepad editor.
2. Find the area of the file where entry information resides and
enter one or more RAC names or IP addresses.
Use an asterisk (wildcard) for any part of an IP address. If you
list more than one RAC, you must separate names or IP
addresses using commas.
