This one is definitely for me.
I was having problems logging into my AWS EC2 instance. I connect through a custom port (security overkill; sad face), but the problem seemed to be the key.
I went to the AWS console and generated a new key pair, downloaded it, and tried to connect using that, but to no-avail.
It seems that each instance is limited to a specific
*.pem file. May be
obvious to most, but this is a reminder to myself.
I need that file to connect to the instance with. I can't (or at least, don't
know how to) create another
pem file to connect to the instance with. It's
strange, and frustrating, but I'm sure this'll help me later on when I try to do
this exact thing :P
Thus, store that key in a secure place (eg. password-protected file in Dropbox, email, etc.), and then access that whenever needed.
