Re: "mysql_connect(): Client does not support authentication protocol requested by server; consider upgrading MySQL client"

Telling new users to use Ethereal to diagnose this problem is not good advice. This is like telling someone with car troubles that they need to use an electron microscope to diagnose it.

MySQL uses neither CHAP nor MD5 to perform authentication. MD5 is not an authentication protocol, it's a message digest algorithm. Anyway, MD5 is not used in MySQL's authentication protocol.

MySQL 4.0 and MySQL 4.1 (and later) do use different password-hashing algorithms during the authentication steps. You can get more information about the algorithm difference here: http://dev.mysql.com/doc/refman/5.0/en/password-hashing.html
