SFTP problems...

Hello beginners@perl.org,

I just install Net::SFTP on my machine via PPM (randy kobes
repository), and ran this code:

#!/usr/bin/perl -w
use strict;
use warnings;
use Net::SFTP;

my $host = '11.11.111.11';
my $user = 'root';
my $pass = '*********';

my $sftp = Net::SFTP->new($host,user =>$user,
password=>$pass,
debug =>1,
ssh_args=>[port=>22] ) || die "Can't connect $@\n";
print "Connected\n";

__END__

gives me strange output:

branog: Reading configuration data /.ssh/config
branog: Reading configuration data /etc/ssh_config
branog: Connecting to 66.98.212.99, port 22.
branog: Remote protocol version 1.99, remote software version OpenSSH_3.9p1
branog: Net::SSH::Perl Version 1.25, protocol version 2.0.
Use of uninitialized value in concatenation (.) or string at D:/Perl/site/lib/Ne
t/SSH/Perl/SSH2.pm line 41, <GEN0> line 1.
Use of uninitialized value in concatenation (.) or string at D:/Perl/site/lib/Ne
t/SSH/Perl/SSH2.pm line 47, <GEN0> line 1.
branog: No compat match: OpenSSH_3.9p1.
Your vendor has not defined Fcntl macro F_SETFL, used at D:/Perl/site/lib/Net/SS
H/Perl.pm line 214.

it seems, I don't have /.ssh/config nor /etc/ssh_config, but I don't
think this is causing error. Line 41 from SSH2 is:
$ssh->{config}->set('identity_files', [ "$ENV{HOME}/.ssh/id_dsa" ]);

si I put infront on my script:
$ENV{HOME} = '';

now, I don't get 'Use of uninitaialized value...' errors, but last
error still remain.

line 214 from Perl.pm is:
fcntl($sock, F_SETFL, O_NONBLOCK)
or die "Can't set socket non-blocking: $!";

but this I really don't know how to cheat it...

Also, when I think about this, main errors are these:
branog: Remote protocol version 1.99, remote software version OpenSSH_3.9p1
branog: No compat match: OpenSSH_3.9p1.

so it seems, local SSH can't comunicate with remote version of SSH
(I'm right?). Where I can find list of supported SSH versions (so I
should add this one:)

Yeah, it looks like the server is version 1 of ssh, while you are
running ssh2 on your client.

You could try adding a
protocol => 1,2

to your %args . Adding ssh options to sftp can be a little
tricky, here is one way to do it. Untested (and I don't have windows)

########################################
################
my %ssh_options = (
protocol => 1,2
);

my %args = (
username => $user,
password => $pass,
debug => 1,
ssh_args => (options => \%ssh_options)
);

my $sftp = Net::SFTP->new($host, %args)

########################################
###############

Goodluck. Googling for answers might help.

now everything works under win32. The SFTP under win is tricky thing,
but it seems, it works good.

problem was original Net::SFTP which calls NET::SSH::Perl

You should use the SSH WIN32 port on all windows platforms. Or else it can get UGLY !!
