MySQL 5.6 Master Slave Replication on RHEL 6.5

[Mubashar Iftikhar]

I have one "Master" and "Slave" Machines & I am using "MySql5.6" and "RHEL6.5"

Actually, I was trying to create replication between these two machine Master and Slave.
But my problem is that the slave is not communicating with master and the problem appears just like that here below i.e.

I want the slave should communicate with master and replication process should have to start.

How can I resolve this problem?
