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

[Ian D. <Ian...@bd...>]

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 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 .
