Bug Description
I had an instance up and running for hours, quite successfully. I left it alone for awhile and when I went back to that cmd session the window was dead, as when you shell into another machine and drop the vpn. In that case the entire window is unresponsive.
I tried opening another session and logging in from there. no good.
I tried rebooting the instance and then logging back in. no good. I do not believe the instance rebooted at all.
I did a describe-instances and it showed as running.
I did a terminate-instance and it shutdown.
I restarted it and still can not get in. To my knowledge nothing happened at the cluster.
No matter what I do I receive, after a suitable delay....
ssh: connect to host 192.168.3.100 port 22: Connection refused
I tried the private ip address with the same results.
I suspect that isn't enough for anyone to diagnose what happened, unless it is a known bug.
Where should I look for the answer, and better yet, what would prevent that in the future. It had been running fine. I had a mysql as well as tomcat 6 tasksel up and running on it. I had copied over a complete over 2M row database and was accessing it through the instance, until it went silent.
Thanks,
Walt
There is more history and documentation in Question #112157
Effectively I am running the cluster controller of a managednvlan UEC on an instance of Ubuntu 10.4 Desktop. What I had noticed, over time is running instances would go deaf, often times with what looks like valid IP addresses listed in the describe-instances output. Both the public and private IP addresses would be unavailable.
What's odd is that in the case of an intervening vpn session after the vpn session was closed, the ip endpoints to that cloud instance were removed.
Even if there were a separate dedicated cc would not one lose connectivity from the client machine? My existing (and previously existing) network was the 192.168.0.xxx served by my wireless router. The segment reserved for the cloud instances public IP address was 192.168.3.0->3.50 or some such limited range.
What is avahi and why is it withdrawing the endpoint IPs to the cloud instance?
