I have installed Deb on my laptop and reused my old Deb 7 .ssh directory. I can now ssh into the existing remote servers but cannot ssh into my laptop from them (as a normal user)--I always get asked for a password. So the remote servers recognize my old Deb 7 keys, but apparently my laptop doesn't recognize the other servers' keys.
I have compared files: /etc/ssh/ssh_conf /etc/ssh/sshd_conf /etc/pam.d/ssh/sshd between the laptop and the remote server and can see no significant difference for a normal user. I can also see the host names in the .ssh/known_hosts file. I do see that my laptop host's entries in the remote host's known_hosts are of type "EDCSA" while the remote host's entries in the laptop's known_hosts file are of type "RSA." Can anyone suggest where to look next? Thanks. Best regards, -Tom
