I am trying to set up mysql replication on 2 systems but Once I get it
going, I get the following an error 1062,
which is a duplicate entry and my 'slave status' shows:
Slave_IO_Running: Yes
Slave_SQL_Running: No

* Someone is changing the POS for replication.

SHOW SLAVE STATUS \G
SHOW MASTER STATUS;

should not happen if the slave is properly cloned
