amazon ec2amazon-web-servicespingssh
I was following this tut on how to set up a EC2 instance on Ubuntu but qhen trying to execute ssh command on my IP address, I had an operation Timeout.
So I tried to ping it but no chance neither.
got Request timeout
Any idea what to do to make it working ? Status is green on my dashboard.
Thanks !
Have a look at your security groups in your AWS Panel
Make sure nothing is blocking it there.
Unresponsive != no heartbeats. The kernel is still running. AWS has no way of knowing that you've consumed all of your memory.
AWS Cloudwatch monitoring is really just the bare minimum you should do. If you need more detailed monitoring, you'll need to roll your own.

AWS security groups block ICMP (including ping, traceroute, etc.) by default. You need to explicitly enable it.
