I am having difficulty logging onto my Amazon ec2 instance. I set it up,
downloaded the key. At first it complained because my permissions were setup
correctly. Then I executed:
chmod 400 myKey.pem. When I try to log in,
I still get:
Permission denied (publickey)
Next I deleted all of my keys and tried fresh:
rm -rf ~/.ssh
I am confused by the other responses to this question. It seems like 1000 things could go wrong, and I'm not sure where to begin. I ran it with the -v option and it generated the following output (see below). Which I don't know exactly what to make of it.
As a beginner working through this, what should I try next?
