Summary: FTP transfert in acsii

Initial Comment:

The ftp transfert in ASCII mode fails ( the transfert is
already in binary :( ).

I was working to get a MVS file ( transfert protocol have
to be in ascii mode ).
I use de version 7.9.6 of curl on Win32 ( windows NT 4.0
sp6a ) and the same proble appear with libcurl for PHP.

Thank you.

Closing this. This is arguably perhaps a bug in that is
doesn't tell the user about this situation.

Aha!

This explains a lot. Unfortunately, when using a HTTP proxy
for doing FTP transfers, such as the one you do when this
fails, the protocol doesn't allow all the controls one
otherwise have when doing FTP transfers.

This is an example of such a shortcoming. You just can't
make ASCII FTP transfers when going over a http proxy.

Sorry. This is a protocol problem, not implementation.

Ok.

When i do :

C:\curl -v -i -# -B -U proxyuser:pass -x 10.115.132.102:8080
ftp://ftpuser:pass@x.x.x.x/'name_of_file_in_mvs' > file1
* About to connect() to 10.115.132.102:8080

---> here the file1 is wrong like it was transfert in binary mode
---> the problem is the same with the php library

But I have make another test :

C:\curl>curl -v -i -B -#
ftp://ftpuser:pass@x.x.x.x/'name_of_file_in_mvs' > file2
* About to connect() to ftpuser:pass_at_x.x.x.x:21

---> here the file2 is right it was transfert in ascii mode

I hope it will help you.

OK, I still need more details to get a clue.

Can you please run the curl command with -v and -i and
display what it'll show you? Edit out sensitive before you
post. Just saying "it doesn't work" doesn't really help me
to understand what goes wrong.

No upload, i'm speaking about FTP download.

And i could not give you the url because it's a special
machine whose's acces is restricted.

If i use the windows FTP in ascii mode, than it works.
But with curl in binary or ascci mode the result is the same
as windows FTP in binary -> the file is not good

Are you talking about a FTP upload here? Because if that is
the case, then yes, this is a missing funcionality that is
also mentioned in the TODO-file that we want to have fixed
one day. Feel free to submit patches that offer this!

If you're talking about FTP dowload here, can you please be
more specific and also if possible provide a working URL
with protocol dump that illustrates the problem?
