To open port 80 on my Amazon AMI VM, I need to do "ec2-authorize default -p 80". Should I do this on my home machine or on the VM itself?
Since running ec2-authorize requires a private key, I'm guessing I run it on my home machine for security. I'm confused because ec2-authorize comes preinstalled on my VM (it's in ec2-user's path, but not root's), and that's the one place I shouldn't use it? Or is this for those cases where one VM controls others?
