The below method provides no security or authentication, so we recommended not to use. If however heartbeat communicates over a private link such as in our case (serial and crossover cable) there is no need to add this additional security.
Step1
[root@node1]# vi authkeys
## /etc/ha.d/authkeys auth 1 1 crc
The preferred method is to sha encryption to authenticate nodes and their packets as below.
## /etc/ha.d/authkeys auth 1 1 sha HeartbeatPassword
Step2
Give the authkeys file correct permissions.
[root@node1]# chmod 600 /etc/ha.d/authkeys
Step3
Copy the authkeys file to node2 so they can authenticate with each other.
[root@node1]# scp /etc/ha.d/authkeys root@node2:/etc/ha.d/
Step4
Login to node2 – your backup domain controller, use the exact same configuration as the primary domain controllers configuration files for heartbeat.
