in thread A little demo for Net::SSH2

To use Shell method on Active Perl on windows use: 
#!/usr/bin/perl
use warnings;
use strict;
use NET::SSH2;

my $host = ""; # use the ip host to connect
my $user = ""; # your account
my $pass = ""; # your password

my ($len, $buf);

my $ssh2 = Net::SSH2->new();
#$ssh2->debug(1);
if ($ssh2->connect($host)) {
  if ($ssh2->auth_password($user,$pass)) {
      #shell use
      my $chan = $ssh2->channel();
      $chan->shell();

      $chan->write("ls -a\n");
      select(undef,undef,undef,0.2);
      print $buf while ($len = $chan->read($buf,512)) > 0;

      $chan->write("who\n");
      select(undef,undef,undef,0.2);
      print $buf while ($len = $chan->read($buf,512)) > 0;
      #$chan->send_eof();
      $chan->close;
  } else {
    warn "auth failed.\n";
  }
} else {
  warn "Unable to connect Host $@ \n";
}

    Thanks for the start, but I found your code would hang on my system. But, all I had to do was make the channel non-blocking and it worked. 

    if( $ssh2->connect($host) ) {
    if( $ssh2->auth_password($user,$pass) ) {

        #shell use
        my $chan = $ssh2->channel();
        $chan->blocking(0);
        $chan->shell();

        $chan->write("ls -a\n");
        select(undef,undef,undef,0.2);
        print $buf while defined ($len = $chan->read($buf,512));

        $chan->write("who\n");
        select(undef,undef,undef,0.2);
        print $buf while defined ($len = $chan->read($buf,512));

        $chan->close;
    }
    else {
        warn "auth failed.\n";
    }
}
