Hi,

using freebsd 5.2 release.

Below you can see what is not commented out in my sshd_config file, which is almost 
the default:
#$FreeBSD: src/crypto/openssh/sshd_config,v 1.33 2003/09/24 19:20:23 des Exp $
#VersionAddendum FreeBSD-20030924
Protocol 2
ListenAddress x.y.z.x
LoginGraceTime 60
PubkeyAuthentication yes
PasswordAuthentication no
PermitEmptyPasswords no
PrintMotd yes
PrintLastLog yes
AllowGroups ssh
Banner /usr/local/etc/ssh/banner
Subsystem   sftp/usr/libexec/sftp-server
I'm using ssh windows client version 3.2.9 from:
http://www.ssh.com
I get a passphrase prompt, I enter xyz, press enter, than I'm prompted to enter my 
password, I enter the password and I have my prompt:
[EMAIL PROTECTED]:
Is this a security bug, a misconfiguration or what?

I thought I had disabled password authentication with: PasswordAuthentication no

thx a lot

you did.  from ssh's point of view.  however, pam is enabled, and it 
allows password authentication.  to do what you're asking, edit 
sshd_config again, and toggle this line

# Change to no to disable PAM authentication
ChallengeResponseAuthentication no
this is my fix, it allows only pubkey logins.  i'm sure this is also 
possible with PAM, and actually, would love to know how that works too :)

hope this helps ~j

Does anyone have any idea on how to require a pubkey AND a password?  I 
don't want either one to be enough, but want both...

Thanks
