I've got one question regarding Ubuntu Juju deployment, on AWS cloud. I'm using Bash to write my hooks. At the end of the install hook/script, I have lines that expose some of my TCP ports(80,443,5666 etc)
open-port 80/tcp open-port 443/tcp
My question is how can I expose ICMP ports in a similar manner? ICMP ECHO request, ICMP ECHO reply is what I need.
The reason for this is that we use Nagios for monitoring of our EC2 instances. Alarms fire off right away, complaining that instance is not reachable, since Nagios relies on ICMP for basic remote host check.
