Technically, the error I'm seeing is from Net::SSH::Perl, but it cropped up through use of Net::SFTP.

I have a very small script that I'm using to test connectivity with an SFTP server:

#!/usr/bin/perl -l

use strict;
use Net::SFTP;

my ( $host, $user, $pass ) = ( ... );

my $sftp = Net::SFTP->new( $host, 
    user => $user, password => $pass, 
    ssh_args => [ debug => 1 ] );

However, there seems to be a problem with this that I have been unable to track down so far:

I am able to connect to the server through the sftp command line utility just fine. The module usage seems to be pretty straight-forward, but I suppose I could be missing something. I've tried passing it both SSH1 and 2, and all of the compatible cyphers for each through 'ssh_args', but with no luck.

If anyone more experienced than I with Net::SFTP or Net::SSH::Perl could shine some light on this for me, that would be most excellent.
