ordinary users unable to login on the SSH server

Maaz — Wed, 10 Sep 2008 02:09:04 GMT

SSH Server OS: SLES 10 SP 1 x86_64
SSH Server IP: 192.168.0.1

# rpm -q openssh
openssh-4.2p1-18.25

# ssh -V
OpenSSH_4.2p1, OpenSSL 0.9.8a 11 Oct 2005

every thing is default.

root can login on the ssh server, no problem.

but ordinary(non-root accounts) users are unable to login on the SSH server from any ssh-client machine.

Hi,

It looks like you don't have any keys configured on the client:
debug1: identity file /root/.ssh/identity type -1
debug1: identity file /root/.ssh/id_rsa type -1
debug1: identity file /root/.ssh/id_dsa type -1

How has this been set up and what kind of authentication are you trying to use?

Maaz — Wed, 10 Sep 2008 06:44:21 GMT

Thanks Ollie Rowland for reply.

>How has this been set up and what kind of authentication are you >trying to use?
this is a default setup. no additional configuration. we use to login on the server using password, we didnt configure the password-less(automatic login) login... again this is just the default setup, without any additional configs.

Re: ordinary users unable to login on the SSH server

Maaz — Wed, 10 Sep 2008 06:46:24 GMT

attached is /etc/ssh/sshd_config

Re: ordinary users unable to login on the SSH server

Ollie Rowland — Wed, 10 Sep 2008 10:17:31 GMT

Hi,

The line
PasswordAuthentication no
looks a bit suspect.

Can you comment it out (or set it to yes), restart the sshd and try again?

Re: ordinary users unable to login on the SSH server

Maaz — Thu, 11 Sep 2008 01:43:49 GMT

Hi Ollie Rowland thanks for continuous support.

either I put the "#" before PasswordAuthentication or set PasswordAuthentication to "no"

restart the sshd.

then now atleast I got the password prompt, but rejected with the same error i.e
Permission denied (publickey,keyboard-interactive).

# ssh bilal@192.168.0.1
bilal@192.168.0.1's password:
Permission denied, please try again.
bilal@192.168.0.1's password:
Permission denied, please try again.
bilal@192.168.0.1's password:
Permission denied (publickey,password,keyboard-interactive).

Hi,

I think be default the root user is not allowed to log in via SSH like this.

You have 2 choices:
* Log in as a non-root user and use su to switch to root

* Add the line "PermitRootLogin yes" to sshd and restart the sshd

For security purposes, I would personally choose the first option.

Maxim Revutskiy — Fri, 12 Sep 2008 06:55:30 GMT

Just in case, does ordinary users can login via local console?

And could you post your /etc/pam.d/sshd ?

YES,
