[gentoo-user] any SSH guru on the list

[Joseph]

I'm having problem logging into my Gentoo server from Knoppix booted PC
Connection between two Gentoo servers works fine.

I narrow it to the authorization method ssh is trying to use.  When I'm
logging from Getnoo workstation the authorization ssh is trying to use:
service ssh-connection method publickey

When I try to login from Knoppix booted PC, ssh is trying to use:
ssh-connection method keyboard-interactive
Here is debug-log from Knoppix (failed) vs Gentoo (successful) login
attempt:

Gentoo (success)

man ssh_config
look for "PreferredAuthentications"

Thanks for the pointer.  According to the manual the default for ssh
PreferredAuthentications is:
hostbased,publickey,keyboard-interactive,password
So it should work but for some reason or another Knoppix is not
defaulting to publickey; even though I have public key
in /knoppix/.ssh/authorized_keys

Adding to /etc/ssh/ssh_config
PreferredAuthentications publickey
has no effect.  Do I need to log-out and log-in in order to take it
effect?

What are the permissions for / /home /home/knoppix /home/knoppix/.ssh
/home/knoppix/.ssh/authorized_keys?

No.

Solved!
In my case it was a logical error, it appears had copied Public-Key from
from server I was logging into to the computer I was logging from.  And
it suppose to be other way around. 
I've learned my lesson now.
