Public Key Private key VS. password

[neonep]

Hello all,

I wrote a script in Perl that uses sftp to put and get files from different servers. I have set up a public key/private key authentication on my box and so it never prompts for a password when I run the script for sftp'ing to another server. What I want to happen is, if someone else tries to run the script, if the public key/private key is not set, instead of sftp prompting for a password and hanging there, I just want it to throw an error and quit. How would I do that?
Your help will be greatly appreciated.
Thanks.

Show us some code, there's got to be a way to test the condition.

This public Key, Private key, that's not the server certificate ...?

I use an SFTP client, and had no idea you could this PGP setup

You could probably use Expect, or Perl::SSH to setup a secure shell to the client first, and if that fails, so too will the SFTP, assuming the users are properly setup

Here's a detailed explanation of my problem.

$rc = system("/usr/bin/sftp -b $command_file $userid\@$server >> $results_file 2>> $results_file");

the $command_file has the information on lcd and cd and stuff for the sftp.

if someone WITH a public key private key set up on his box and the server runs this script, it will easily copy the files without prompting for a password.

But if someone WITHOUT a public key private key set up on his box and the server wants to run my script, when it reaches the above line, it prompts for a password.

If that's the case, instead of prompting for the password, I want to print out an error saying something like "Public key private key authentication not set up"

I want to do this, because this script will be scheduled to run automatically and there will be noone to feed the password manually. The errors ( like the one I want ) will be logged in a log file though.

I hope this helps you understand my problem.

You need to look at Net::SFTP on

http://search.cpan.org

It should crap out at all the right points w/o waiting for user input
