corrupt files after ftp transfer

'chris' — Sat, 19 Jun 2004 14:07:50 GMT

hi

I transfer TEXT files via ftp in ascii mode
from linux to the WIN2000 ftp server using a perlscript:
-----------------------------------------------
my $ftp = Net::FTP->new ($server, Timeout => 9000, Debug => 3);
$ftp or die "$server: cannot connect: $@";
$ftp->login ($user,$passwd) or
die "$_: Could not login: " . $ftp->message;
# Put file
$ftp->put ($file) or
die "$server: cannot put $file: " . $ftp->message;
$ftp->quit;
-----------------------------------------------
but files after transfer are corrupt.
I get between text lines someting like:
Â 03
or some special not standard symbols, that I cannot copy to the browser.

knows someone, what reason could be and how can I fix this problem ?
I cannot transfer these files in binary mod

I've tried to put:

$ftp->ascii();

but it still doesn't help.

Chris,

I bet what you are seeing on Windows is the unix control characters. It is better to convert the unix format file to dos format before you ftp the files. You can do this with simple linux command called "unix2dos",

eg: #unix2dos myfile.txt --> would convert the linux text file into dos format and replace it.

To see more options with unix2dos,
# man unix2dos
use -n option to write a new file instead of replacing it.

In your scenario, you may put a shell script first to do the format conversion and call the perl script from the shessl script.

regds,
Abdul.

firewall was a problem, because our firewall doesn't support autosense.

I set the port on the sitch to half duplex and now it works without any problems.
