Subject: 23.2; Open remote files (via FTP) fails on (my) Windows XP port
Date: Tue, 14 Sep 2010 20:57:49 +0200

[Message part 1 (text/plain, inline)]

Hello,

I'm testing the opening of remote files with GNU Emacs.

That works fine in my Ubuntu 10.04 version (GNU Emacs 23.2.1
(x86_64-unknown-linux-gnu, GTK+ Version 2.20.1)), but fails in my
Windows XP one (GNU Emacs 23.2.1 (i386-mingw-nt5.1.2600)).

To reproduce:
1.- Start Emacs (anyhow).
2.- Type `C-x C-f'.
3.- In the minibuffer, write the PATH of a remote file, accessible via
FTP. For example: `/ftp:ftp <at> ftp.mozilla.org:/pub/mozilla.org/README'.

Am I doing something wrong? Or is it a bug? (This same procedure works
in the Ubuntu port!!)

Thanks in advance.

I've attached the contents of the *Messages* buffer
(standard_messages_buffer.txt), and the *ftp
ftp <at> ftp.mozilla.org:/pub/mozilla.org* buffer
(ftp_messages_buffer.txt).

I would suspect some network setup, because where you get your
connection closed:

    257 "/"
    cd "/pub/mozilla.org/README/"
    550 Failed to change directory.
    cd "/pub/mozilla.org/README/"
    550 Failed to change directory.
    cd "/pub/mozilla.org/"
    250 Directory successfully changed.
    ls -al c:/DOCUME~1/admin/LOCALS~1/Temp/ange-ftp4012GxJ
    Connection closed by remote host.
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I get the directory listing:

Maybe. But it that same Windows machine, I can open that same remote
file with an Internet Browser (URL
"ftp://ftp.mozilla.org/pub/mozilla.org/README").

Now I wonder this: as you can see, the last command previous to the
error is an "ls" command. That is a UNIX shell command, not available
in Windows machines AFAIK. So, I guess Emacs somehow emulates it. But
I'm tried to run the command with `M-!' and I get this error:
> 'ls' is not recognized as an internal or external command,
> operable program or batch file.

So... Do I need to install some extra tools in my Windows machine to
make "ls" and other UNIX commands work?.
(I've just downloaded the file "emacs-23.2-bin-i386.zip", extracted
their contents into my hard disk, and invoked "runemacs.exe").

This is usually a sign that you are on a NATed connection and require
passive mode.  The Windows FTP client does not support passive
mode. Alternative FTP clients for Windows exist to get around this and
other restrictions of the standard Windows client.

In this case it is an FTP command, not a shell command, so whether it is
installed locally is not relevant.

You must be right, because I have Windows XP installed on top of
Ubuntu, using Virtualbox, and the guest OS has an NATed network
connection.

Thank you.

[Message part 1 (text/plain, inline)]

I'm reopening this bug report, because I'm experiencing it with the
latest Windows build of Emacs, on a Windows 7 system (real, not
virtualized).

0. emacs -Q.
1. C-x C-f /ftp <at> ftp.mozilla.org:/pub/mozilla.org/README

I don't understand why Emacs is unable to visit that file, given that:
 * My browser can show the contents of the file without problem.
 * I also can get the file using the standard windows ftp client (I
sign in with user="ftp" and pass="ftp").
 * My network connection has nothing special: An ethernet port
connected to a cable modem.

I've attached the contents of the ftp session buffer.

TIA.

I'm using a trunk build, on a Windows 7 Home Premium SP1 64-bit, and
it works. Apparently the difference between your log and mine is the
use of passive mode.

Well, I don't know the reason for that difference. I've not tweaked
anything in Emacs nor Windows.

BTW, I forgot to attach the contents of the *Messages* buffer. I'm
doing it now; it may give a clue.

I've tried to reproduce it on a Windows 7 Enterprise 64-bit
machine. Using Emacs 25.1.

Your example ftp.mozilla.org is unresponsive. So I've tried to open

<PATH-TO-EMACS>\emacs.exe -Q /ftp:ftp <at> ftp.gnu.org:/README

It works. There is no special ftp client on this machine, just the
default MS ftp client 6.1.7601.17514 (still not able to run passive
mode). And I run it from behind a NATed router.

So I don't know what else I shall do in order to reproduce it. Could
you, pls, check with a recent Emacs whether you still experience
problems?

Best regards, Michael.

I've just tried your same test, from an environment similar to yours:
  <PATH-TO-EMACS>\emacs.exe -Q /ftp:ftp <at> ftp.gnu.org:/README

and it works here too.

For the record, here I have Emacs 25.1 (compiled from the emacs-25
branch 4 days ago).

So I think you can close this bug.  I can close it too.  Should I?

Thank you.
