I'm having inexplicable trouble connecting to my EC2 instance. I'm using the below, and no solution seems to quite be working properly. Thank you very, very much for your time!

ssh -v -i MikesKeyPair.pem ec2-user@ec2-54-83-106-238.compute-1.amazonaws.com

You really need to check on the server for what sshd is logging but with the info provided my initial guess would be that the server is rejecting the keys. As to why - see the server logs it initially I'd guess incorrect permissions.

  • Thank you very much for your help Iain. I'm going to try looking at this and will let you know. I don't have direct access to the ec2 server in question... but you're saying that it's not allowing permissions? – Goldnuggets Mar 16 '15 at 19:20
  • @Goldnuggets Read up on the permissions required on the relevant files and directories for ssh on both the client and the server. – user9517 Mar 16 '15 at 19:22
