Hi! The 127.0.0.1 issue is actually a MySQL issue, unfortunately. " On Unix, MySQL programs treat the host name localhost specially, in a way that is likely different from what you expect compared to other network-based programs: the client connects using a Unix socket file. The --socket option or the MYSQL_UNIX_PORT environment variable may be used to specify the socket name. " So not really something we could do much about. Aki
