I try sftp with batch file "-b' option and it fails with Permission denied though entry exists in known_hosts.
authorized_keys is not setup.But as per the configuration, I expect password authentication to continue..this is not happening.
Could you help here to identify for the reason?

Hi

This is because your user doesn't have the their own keys shared in the '~/.ssh/authorized_keys' file.

If you read through your config, you'll see that you've got "PasswordAuthentication no".

This means, no matter what, you won't be asked for a password.

Re: Permission denied (publickey,password,keyboard-interactive).

Hi

please check that you have the own keys shared in the '~/.ssh/authorized_keys' file.

I removed the comment for PasswordAuthentication in sshd_config, restart the sshd and checked again.The password is prompted in the first case but when I use a batch file, it is not prompted.I dont understnad why?

Passowrd prompted:

The connection is successful if I set authorized_keys.But I need the password to be prompted incase for machines which do not have the keys set in authorized_keys.
That is -
My script will check for public key first.If it does not exist, it would check for password prompt.

Nishita Kumar — Tue, 27 May 2008 05:49:04 GMT

Hi,

If you see the sftp manpage, it states that sftp -b can only be used in conjunction with non-interactive authentication. This is why you are not prompted for a password when you use sftp in batch mode.

Re: Permission denied (publickey,password,keyboard-interactive).

Sachin Rajput — Thu, 15 Dec 2011 19:04:29 GMT

Hi ,

Add the below line in your config file : /opt/ssh/etc/sshd_config

========

UsePAM yes
==========

After that restart the ssh daemon and that should resolve your issue .

Ops! ppk files ist not PEM formated, but generated by the software PuTTY, the PuTTY Key Generator (PuTTYgen) , so it is not usable by the openssh software. Try to use the PuTTY to export the ppks files to a formal openssh keys.
