ssh is still asking for a password, even though I did everything by the book. I have included all output, right from the start. Any ideas?
Thanks!

- Generating public/private rsa key pair and checking permissions on local host
Edit: => As it turned out, this was the problem. The key pair needed to be generated on the remote machine, not on the local machine, as «Mat» pointed it out in the very first comment. Please read the many comments in the solution if you need to know how we got there.
on local computer:
mms: admin$ ssh-keygen -t rsa

I can't look into the log files (/var/log/auth.log or /var/log/daemon.log do not exist and I don't know where they are located). Local computer is a Mac running 10.10.5 and remote computer is a Mac running 10.6 (which can't be changed).
Thanks!
id_dsa.pubinstead ofid_rsa.pub- the default on the server forRSAAuthenticationwill beyes, but it applies toSSHprotocol version1only so maybe the server is set to only accept protocol version2, and hence notRSAauthentication (I am just guessing ...)
