I have created a mysql master-slave configuration and things look fine . the " show master status;" on slave doesnt show any error . this is the output

Am i missing something
SHOW MASTER STATUS
too, the top bit is missing I think.SHOW MASTER STATUS
on the slave. This information is not relevant unless the slave is also serving as a master for other slaves further downstream.SHOW PROCESSLIST
on the master, do you see the incoming connection from the slave? You should. Also, I would trySTOP SLAVE IO_THREAD;
thenSTART SLAVE IO_THREAD;
on the slave and see how the output ofSHOW SLAVE STATUS
(on the slave) changes, if at all.
