Hi All,

I built a code for pushing the data from my Windows machine to Unix machine using the SFTP protocol. For the purpose I used NET::SFTP::Foreign. The part of code is mentioned below.

#!c:\Perl\bin\perl
use Net::SFTP::Foreign;
use Net::SSH2;

$user="abcd";
$passwd="abcd@1234";
$host = "192.168.10.2";
$port = "22";

$sftp = Net::SFTP::Foreign->new($host, backend => 'Net_SSH2',username 
+=> $user, password => $passwd, port => $port) || die $sftp->error;
print " SFTP Connected \n";

for ($i = 0; $i <= 23; $i++)
{
$filename = "testfile".$i.".csv";
$sftp->put("c:\\documents\\$filename", "/usr/home/abcd/$filename"|| pr
+int $sftp->error;
print $sftp->status;
}

Using the above code, I am able to transfer the files but as soon as the it tries to transfer the 4th file it gives me error "write failed: LIBSSH2_ERROR_EAGAIN (-37): Unable to send channel data" and Status as "Connection lost". All the subsequent files while putting generate error "Connection to remote server stalled" with status message "Connection lost". I need to run my script few more times to transfer remaining files.

The OS is Windows 7, Perl version is v5.10.1 and Net::SFTP::Foreign version is 1.62.

Can someone please guide me why connection is getting stalled after transferring few files and what is way out?
