Azure – Disable PING Broadcasting

When LifeKeeper is used in a cloud environment, it may not be possible to use broadcast ping to find other machines on the subnet. Therefore, this should be disabled by changing the configuration of LifeKeeper as follows:

1. Check the current configuration.

# grep -e NOBCASTPING /etc/default/LifeKeeper 
NOBCASTPING=0 	# Can be used to disable the broadcast ping mechanism 

2. NOBCASTPING must be set to 1.

# cp -p /etc/default/LifeKeeper /etc/default/LifeKeeper.org 
# sed -i -e ‘s/NOBCASTPING=0/NOBCASTPING=1/g’ /etc/default/LifeKeeper 

3. Confirm the change.

# grep -e NOBCASTPING /etc/default/LifeKeeper 
NOBCASTPING=1 	# Can be used to disable the broadcast ping mechanism
