I've recently been playing around with Ubuntu on Amazon Ec2. One thing that bugs me is the default host names it gives your instances.
- Is it permissible to change the hostname of your instance?
- Are there any negative consequences?
- How does adding users work with the certificate based authentication?
I've never used cert based authentication before, I've been told it's more secure. If I add a user
Does he login using the same cert or do I have to generate a cert for each user?Code:useradd dude
