MYSQL ERROR 2049 (HY000): Connection using old (pre-4.1.1) authentication protocol ref used (client option 'secure_auth' enabled)

Question

when I tried to restore all database dump which is in 5.0 version to 5.6 version, it got restored and after that when I tried to reconnect, am getting the following error

Answer 1

On the command line, use something like the following, if you have no choice...

mysql -uTheUseerNAme -pThePassword DbName -h HostName --skip-secure-auth

Hope this helps someone, as this was my problem connecting from a Linux box
