On _each_ node add the following to /etc/ntp.conf --------------------------------8X-------------------------------- keys /etc/ntp.keys trustedkey N --------------------------------8X-------------------------------- On _each_ node create /etc/ntp.keys and add the following line: --------------------------------8X-------------------------------- N M the_passphrase_for_this_key --------------------------------8X-------------------------------- Choose a positive integer for 'N' (between 1 and 65534). It does not have to be "123" or any other specific value. But you must use the same number in your keys file and on the trustedkey line. Use the letter "M" for the second column. The passphrase is just a character string. Generate it however you'd like. The key ID (N) and the passphrase must be the same on all nodes. See http://doc.ntp.org/4.2.6p3/authopt.html for a discussion of authentication options. Symmetric Key authentication (which is what we've outlined above) is discussed at http://doc.ntp.org/4.2.6p3/authopt.html#symm -- Steve Kostecke <[email protected]> NTP Public Services Project - http://support.ntp.org/ _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
