Hello. I'm today following the FreeBSD security how to <http://www.it.daemonnews.org/200108/security-howto.html> to secury my FreeBSD server. I configured dsa ssh access, now I can use my own computer to login to the server with ssh with dsa no problem, no password authentication is necessary. Following the guide I edit /etc/ssh/sshd_config and made sure
PasswordAuthentication no
But I tried restart sshd and even reboot the server, I can always login with password on any other computer.
Please drop me a hint.
Here is my server's configuration:
