I'm trying to do an FTP GET a file from mainframe to Linux.
I have a perl daemon on Linux which issues the follwing commands-

my $ftp=Net::FTP->new($MVSADDR,Timeout=>1800,Debug=>1);

my $olddir = getcwd();
chdir(makedir()) or $ftp=0;

$ftp->login($MVSUSER,$MVSPASS);

$ftp->binary;
$ftp->pasv();

$ftp->get(remote file,localfile);

$ftp->quit;


and I get the follwing messages from FTP server:

220-FTPD1 IBM FTP CS V1R7 at IMSJES2.us.rxcorp.com, 21:48:41 on 2006-06-29.
220 Connection will close if idle for more than 15 minutes.

125 Sending data set G1ZIP01.TST.ET770056.FILE001.SPLIT001
250 Transfer completed successfully.

QUIT
221 Quit command received. Goodbye.

The above script downloads a file of 200 bytes correctly.

However a 50 MB or more file is downloaded as a zero byte file and a successful transfer message is received.

When I manually try to do the ftp for 300 MB file, it downloads correctly in 40 seconds.

Why does the script download a zero byte file?
What do I need to do to have the complete file transferred correctly-whatever the size!!

-Please help.

-Thanks,

I tested out the following code:

Code:

use Net::FTP; my $ftp=Net::FTP->new("www.wellho.net",Timeout=>1800,Debug=>1); $ftp->login("wellho","abc123"); $ftp->binary; $ftp->pasv(); $ftp->get("backups/20060519.sql.gz","ltf.txt"); $ftp->quit;

(password changed before publication, of course!) and it correctly downloaded my 89 Mbyte compressed SQL backup file.

I can't see anything wrong in the code you have posted, but I do note that it's incomplete - perhaps a few lines that you felt to be the important ones cut and pasted from a larger application, and there's also a certain amount of pseudocode in there.  Can I suggest  you start by getting an example as simple as mine working as a test case, like I did, then work up from there; I suspect that your problem and the clues to it lie may not lie in the code you posted.
