Hi, I was just checking this out, and although this node is old, for the benefit of people searching, here is how to do it. In your case, scp_get needs a blessed reference to write to, like an IO::File or IO::Scalar object. You just can't specify the file. Below is a working example

#!/usr/bin/perl
use warnings;
use strict;
use Net::SSH2;

my $ssh2 = Net::SSH2->new();
$ssh2->debug(1);

$ssh2->connect('localhost') or die "Unable to connect Host $@ \n";
$ssh2->auth_password('z','ztester') or die "Unable to login $@ \n";

my $dir = '/home/z';
#get a large file like a 100Meg video file
my $remote1 = $dir.'/hamps_boogie.flv';

use IO::File;
my $local1 = IO::File->new("> 2.flv"); #it needs a blessed reference

$ssh2->scp_get($remote1, $local1) or die "$!\n";

# be warned that you cannot have blocking set to 0
# from perldoc Net::SSH2
# blocking ( flag )
# Enable or disable blocking.  Note that if blocking is disabled, 
# methods that create channels may fail, e.g. "channel", "SFTP", "scp_
+*".
