I'm completely at a loss as to what is preventing my local machine from authenticating the connection that is being forwarded from the remote server.
I've read a ton of the posts on here regarding this and man, I swear I've tried damn near everything.
The guide I've been following can be found here: http://www.zeespencer.com/articles/building-a-remote-pairing-setup/
Basically where I'm stuck at is in forcing passwordless authentication. If I allow passwords in sshd_config, when I connect to pair@pair-server I am prompted for my local user password and am able to login remotely, so I am being forwarded. But, as soon as I turn it off, I get the following
λ ssh pair@pair-server Permission denied (publickey). Connection to pair-server closed.
Verbose output here: https://gist.github.com/anonymous/0c2b3892596d5ded6abb
I currently have my local user key.pub in pair@pair-server's .ssh/authorized_keys which are command directed to ssh back to localhost. pair@pair-server has it's own key, on my computer I've added pair@pair-server's key.pub to .ssh/authorized_keys.
Seemingly relevant lines in sshd_config:
RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile %h/.ssh/authorized_keys PermitEmptyPasswords no PasswordAuthentication no UseLogin no
