I have a simple script which does login, cwd and get - for a tar.gz file. But if file size goes beyond some limit, the resulting file seems to loose a few 100 bytes.
E.g:
On FTP server: 12685981 Mar 22 11:50 test.tgz
File pulled using per: 12685778 Mar 22 12:02 test.tgz
Not sure where I am going wrong. I would appreciate if you could give some pointers. Thanks.
Prapanna.

Did you set BINARY mode?

Yes. Here's the script:
#!/usr/bin/perl -w
use Net::FTP;
my $ftp = Net::FTP->new("ftp.mydomain.com") or die "\nINFO: Cann't connect";
$ftp->binary();
$ftp->login("myid","mypasswd") or die "\nINFO: Failed to login";
print "\nINFO: Login successful. Now getting...";
$ftp->cwd("mydir") or die "\nINFO: Couldn't change directory\n";
$ftp->get("test.tgz");
$ftp->quit;
print "\ndone\n";
I also tried it without binary. But the problem persists. BTW, the 'put' for the same tarball goes thru perfectly fine.

We saw the similar issue in our application. This was caused due to the link speed was reduced from 100mbps to 10mbps.
May be you would like to check on your link speed.

the problem is that you are calling the binary method before authenticating with the ftp server...so you are really using ascii
move the binary line below the login line and you should be fine

Good catch!
Thanks!
