I'm on a MacBookPro. I tried starting an EC2 instance with EMR and Rstudio and Spark. I got a port 22 time out. I asked AWS for help and took down my firewall and restarted my modem. Still, nothing but port 22 timeout.
AWS managed to get one EC2 instance running. Then another. Still, I could not ssh on port 22. I changed the vpc, subnet, security group, etc. Amazon verified that they were correct. I allowed all traffic on IPv4. Still, I could not connect via SSH port 22. I unloaded and launched the plist. I checked another file in nano that clearly said port 22 was for ssh. In fact, it listed all of the ports and their functions. I've read every page on the web.
It has now been two, yes, two weeks, and I am on the edge. What else is there to do except begin litigating the bill I've racked up with AWS and give up?
