How to SSH to EC2 Instance on AWS (for Beginners) - Sending file modes: C0644 20 SampleFile.
I've been working with AWS for awhile and I am not sure exactly happened but after returning to my computer after a week away from AWS there is something wrong with my key pair permissions. Key pairs have never been an issue but when trying to SSH into EC2 instances, I am always getting one of two errors: Failed to add the host to the list of known hosts Followed by Permission denied publickey. OR I am prompted for an instance-specific password Ironically, this comes after the initial prompt ensuring you want to connect. I've tried generating key pairs 3 ways. I am currently preparing for an AWS certification exam so this is obviously a problem I've been dealing with for about a day now and I'm out of ideas troubleshooting wise. Any help would be greatly appreciated. Think you could throw in the output from ssh -v? Obviously scrub sensitive data first. It can usually be ignored but may point to other permission issues on your ssh directory which prevent the use of your keys when connecting. The verbose output will help diagnose that.
