Asked by: howruaz9

I believe Net::SSH::W32Perl is a very useful Perl module. After installing this module with kind help in here. I still have some problems.

1. my($stdout, $stderr, $exit) = $ssh->cmd("exit > /dev/null 2> /dev/null");
    when execute this command, sometime it works, sometime doesn't work.

2. my($stdout, $stderr, $exit) = $ssh->cmd($cmd);
    print "$stdout\n";
    They didn't work. How can I get result after execute a command?

Thanks very much in advance.

#set HOME=C:\IS";
use Net::SSH::W32Perl;
 
$host="testserver";
$user="bnfjghy";
$pass="sdhj3$%ED";
$cmd="ls -l";
 
   my $ssh = Net::SSH::W32Perl->new($host);
      print "\ndone 1\n";
 
   $ssh->login($user, $pass);
      print "\ndone 2\n";
 
   $ssh->session_id;
     print "\ndone 3\n";
 
    my($stdout, $stderr, $exit) = $ssh->cmd($cmd);
      print "\ndone 4\n";
      print "$stdout\n";

Net::SSH::W32Perl was last updated in 2002 and appears to be no longer maintained.  It would be better to use Net::SSH::Perl or Net::SSH2

Which ever module you end up using, you'll need to add proper error handling.
For example:

my $ssh = Net::SSH::Perl->new($host) or die "can't ssh to '$host' $!";

You should also add the following 2 pragmas (to every Perl script).

use strict;
use warnings;

Why are you executing an 'exit' command in the ssh call?

Exactly what are you trying to accomplish with that call?
