If the feature is for unresponsive servers, would SSH really work?
- herpderperator 7y agoI suppose I misunderstood the diagnosis part. My understanding was that it was an API to trigger a kernel panic. > Today, we are announcing a new Amazon Elastic Compute Cloud (EC2) API allowing you to remotely trigger the generation of a kernel panic on EC2 instances. Which can be done with the commands I mentioned in my parent comment.
- deathanatos 7y agoNot really. From the hypervisor's point of view, there isn't a guarantee that the VM is running ssh, is running it on the typical port, that there's a valid log-in, etc. And again, the point of this is for VMs that are unresponsive, and that generally includes SSH. It is remarkably simple to get Linux into a state where SSH isn't going to allow you to log in, or log ins might take 10+ minutes to actually happen. Someone else mentions console access for these things, which is sadly missing in AWS. I'm not sure how you'd take something like console access (very dynamic, keyboard input, screen output? text?) and put it into an AWS API, though. (Their APIs tend to follow certain patterns.)
