Following the tutorials, installed Docker, installed Sandbox, troubleshooted for hours and finally got Ambari up and working. Came back 2 weeks later to do the Atlas tutorials, and can't connect. In OSX terminal, I an starting with command ssh firstname.lastname@example.org -p 8080;. I am getting a Connection refused error. Did I miss some simple step? Thanks in advance.
Looks like the key has changed. On your local system, go into .ssh/known_hosts and just delete any lines related to the sandbox. Then try the ssh again on -p 2222 and you'll be prompted to re-accept the key and should be good to go.
hi @L Hurley
what you want to do is open the known_hosts file in a text editor and delete any lines that correspond with the IP address of the sandbox, which in your case is 127.0.0.1 and then try it again
I did the image reinstalled and did do as you said deleting the info from known_hosts. Now I get the original connection refused error:
[root@sandbox ~]# ssh email@example.com -p 2222
ssh: connect to host 127.0.0.1 port 2222: Connection refused
But, I get an error at the URL. I'm not able to get to Ambari and move on with the darn tutorials. Error:
127.0.0.1 didn’t send any data.
