Solution

Check the permissions on your homedirectory,. SSH directory, and the Authorized_keys file: ifyour SSH server is Running with ' strictmodes on ', it'll refuse to use yourpublic keys in the ~/.ssh/authorized_keys file. Your home directory should bewritable only by you, ~/.SSH should is, and Authorized_keys should be 600
