[Ssh-sftp-perl-users] Problem With Net::SSH:Perl

[cheerla s. <ch....@gm...>]

Hi ,

I am using the following code to connect to the remote host .
use Net::SSH::Perl ;

$scon = Net::SSH::Perl->new ("$host",interactive=>FALSE);
$scon->login("root","$passwd");
print "looking around ...\n";
($output,$errors,$exit) = $scon->cmd("ls -l");
print $output;



When I execute this code , it is prompting for the password .
I want to ssh without prompting for the password .

Please suggest me how I can modify the above code to ssh a client without
prompting for the password .

Thanks in Advance .

Hi

You need to include all of your code when you report problems, or at
least a 'cut-down' fully working program that demonstrates the problem.

 

If you had done so in this case we could have seen that you had not
included the following in your perl program.

 

use strict;

use warnings;

 

I can tell that you have not done so since you your interactive=>FALSE
would have given a warning like

 

Bareword "FALSE" not allowed while "strict subs" in use at ssh.pl line
10.

 

This is doing the exact opposite of what you are expecting. Since you
have not turned on strict and warnings pragmas then perl is converting
the FALSE into a scalar, which is then being evaluated as a true value
so requesting the prompt!

 

If you read the documentation you will see that it defaults to false
(perl false not FALSE) so it should not request the password.

 

A complete example (which I have tested) is as follows.

 

#!/usr/bin/perl

use Net::SSH::Perl;

 

use strict;

use warnings;

 

my $host    = 'your.domain.com';

my $user    = 'root';

my $passwd  = 'secret';

 

my $scon = Net::SSH::Perl->new ($host);

$scon->login($user, $passwd);

print "looking around...\n";

my ($output, $errors, $exit) = $scon->cmd("ls -l");

print "output=[$output] errors=[$errors] exit=[$exit]\n";

 

If this still does not work then you have to double check that you can
ssh onto the host using the credentials you are putting into your
program.

 

Regards

Ian

Hi ,

I exactly used the code given by you by just changing the $host and $passwd
. When I execute that it is still prompting for the password .

So we need to configure SSH for not prompting the password ?

Thanks for the help .

Hi

Two things.

 

First double (triple) check that the username, password combination
works from the command line.

 

Second add the debug=>1 option to the new and post the debug output you
get when you try to make a connection.

my $scon = Net::SSH::Perl->new ($host, debug=>1);

 

Regards

Ian

Hello
             You need to create public/private keys via SSH-keygen
You can refer for any documentation of how to set up password less SSH
login.

I responded earlier that creating password-less public/private keys was
an option, but the code I gave to login using a password is what was
asked for (and frankly easier to set up for the uninitiated than using
SSH-keygen).

 

I agree that passwordless SSH login is a much better solution if only
because it does not require passwords to be 'hard-coded' into scripts or
config files.

 

By the way SreeHari I would seriously recommend *not* using the root
account to try out this script. You should set up a separate user
account with limited access if you are going to be doing this.

 

Regards

Ian
