Disable pinging slaves in Jenkins

jenkins plugins amazon-ec2 system-properties

At the master node, you can change the system property under /etc/sysconfig/jenkins

JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Dhudson.remoting.Launcher.pingIntervalSec=-1"

you can set the system property when you are running the slave (via JNPL):

java -Dhudson.remoting.Launcher.pingIntervalSec=-1 -jar slave.jar -jnlpUrl <Jenkins root URL>

-K

hudson.slaves.ChannelPinger.pingIntervalSeconds - Since: 2.37, Default:300, Frequency of pings between the controller and agents, in seconds
hudson.slaves.ChannelPinger.pingTimeoutSeconds - Since: 2.37, Default:240, Timeout for each ping between the controller and agents, in seconds
