I have an application that runs on multiple platforms (windows, linux, solaris, aix, hpux). and uses SFTP to send files to our host server.
I needed a 64bit windows version, but the underlying libs for SFTP are not ported to 64bit windows (math::Pari, etc)..
so I rewrote the function to use SFTP:Foreign and use SSH2. all works ok so far.. today I received a trouble report, the ftp send fails, leaving a 0 length file on the server.

I am trying to figure out how to debug this.. 

        use Net::SSH2;

        use Net::SFTP::Foreign;
        my $ssh2 = Net::SSH2->new();
         $ssh2->debug($debugFlag eq $true ? 1:0);
         $ssh2->connect($ftpSecureServer)
           or die "Connect failed!\n";
         $ssh2->auth_password($ftpUser, $ftpPW) 
           or die "password auth failed\n";
           
        $ftp = Net::SFTP::Foreign->new(ssh2 => $ssh2,
                    backend => 'Net_SSH2');

from this 
        $ftp = Net::SFTP::Foreign->
             new(host => $ftpSecureServer,
                 backend => 'Net_SSH2',
                 user => $ftpUser,
                 password => $ftpPW);

both use this code to actually send 
           $ftp->put( $zipFileName, $ftpDir."/" . $newname );
           if ( !$@ )
           {
              printl("Transmission complete..\n");
              $rc = $true;
           }
           else
           {
           printl("file $zipFileName upload failed, try later\n");
           }

the 32 SFTP version does 
          $ftp->put( $zipFileName, $newname );
          if ( !$error )
          {
            # etc

setting SSH2 debug gets me the gory details, but nothing really useful 
libssh2_channel_open_ex(ss->session, pv_channel_type, len_channel_type
+, window_s
ize, packet_size, ((void *)0) , 0 ) -> 0x47dc418
Net::SSH2::Channel::read(size = 4, ext = 0)
- read 4 bytes
- read 4 total
Net::SSH2::Channel::read(size = 5, ext = 0)
- read 5 bytes
- read 5 total

anyone have any suggestions?
