Hi, I'm lately upgrading the ntp from 4.6.5 to 4.8.1p, when I use ntpq to add 
server, it prompted for a keyid and MD5 password. I don't know how to get this 
keyid and password. Before the upgrade, the keyid is 0, so it doesn't need 
authentification. Can you tell me how to get the keyid and password? Thank you.
