...ssword authentication always failed while connecting through ssh. The authentication succeeds if attempted through keyboard-interactive authentication. On debugging this we found that Password authentication is not working because it doesn't Use PAM in openssh 3.7.1p1.

Greetings, I recently discovered a problem with OpenSSH 3.6.1p2 and UnixWare 7.1.1 (as well as OpenServer 5.0.X and SCO 3.2v4.2) When I set up sshd_config as follows: PasswordAuthentication no PermitEmptyPasswords yes and try to connect to a password less account ( I know its a F*up, but that's the application ID10Ts .... ) I can get in using the SSH2 version without a valid key, the SSH1 is okay. below is a fix I used, but I am not sure if this is okay. uw7: /usr/udd1/dev #...

HI! Is it possibly to use s/key with PasswordAuthentication at the same time? I mean that when You enter right s/key password You have to enter right shadow password to logon.

Greetings, Problem : Openssh3.6.1p2 on UnixWare 7.1.1 allows access to passwordless account without a valid key when sshd_config has PasswordAuthentication no + PermitEmptyPasswords yes Attempts: Installed maintence pack3 and recompiled both OpenSSH and OpenSSL (0.9.7b) with native c compiler. Recompiled both OpenSSH and OpenSSL (0.9.7b) with gcc (2.95.2). Still the same problem. Looking at auth2.c line 185-190: authenticated = m->userauth(au...

...d Assignee: unassigned-bugs at mindrot.org Reporter: marcel at telka.sk [This is copied from downstream bug report at https://www.illumos.org/issues/10168] The following code fragment in sshd_config is misleading: <pre> # To disable tunneled clear text passwords, change PasswordAuthentication to no. PasswordAuthentication yes </pre> Indeed, Setting PasswordAuthentication to "no" will NOT disable clear-text passwords if ChallengeResponseAuthentication keeps its default value "yes" . One also needs to set ChallengeResponseAuthentication to "no". See...

Hello, We tested OpenSSH 3.9 in Hp-UX platforms for Passwordauthentication under PAM modules.

The debug traces shows that the authentication suceed as keybo...

Hi, We'd like sshd to listen on port 22 with PasswordAuthentication = no and port 2222 with PasswordAuthentication = yes. At the moment, it seems the only way to do this is to run two sshds, one per port. Since Match blocks already allow PasswordAuthentication to be set, if the Match keyword itself allowed testing of the server port to which the incoming connecti...

I have modified /etc/ssh/sshd_conf to have these settings: ChallengeResponseAuthentication no PasswordAuthentication no UsePAM no I then restarted the ssh daemon (/etc/init.d/sshd restart), but it still allows the user to login using their password.
