Does it mean you are able to browse the directory "/Volume_1" in
dired? Strange.

Could you, please, provide the ange-ftp buffer for a whole session,
including browsing through the directory "/Volume_1" as well as
creation of files, editing files, creation of directories inside this
directory?

Best regards, Michael.

Since it works for me with the same configuration (GNU Emacs 22.1 /
Tramp 2.0.55), I believe this is related to either your FTP client or
server. But we'll see. Btw, which versions of FTP client and server
are involved?

No surprise. Internally, a complete different machinery is working for
you. And which problems with long file names are you running into?

Well, the problems are that it abbreviates the file-names. 
So, concretely.

I wanted to copy a whole batch of files, all with similar file names
(photos, whose file names carry the date-hour-minutes etc which makes the
file names long), So I marked all of them in dired, copied all of them over
the net in a batch to the file-server, using "smb" as protocol. But that
breaks, as some of the files in the target system get the same file-name
via abbreviation, which results in name clash and the copy-batch stops at
that point.

ok. I will post the infos about FTP-version, the protocol the evening then.

Is this the SMB server which abbreviates the filenames? Or is it
because of Tramp, which cannot handle such filenames (maybe containing
spaces, or so)?

Hi,

so, here is the FTP-Buffer. Note that it contains 2 parts, one that is
``automatically'' done when I am operating in dired mode. The very last
part reflects the interaction, when _I_ myself use the FTP-buffer as
interactive shell to operate the ftp-protocol.

The file structure is /Volume_1 at the root.  When I logon to
the directory 

      msteffen@192.164.1.4:

I get the root / of the file system displayed in dired (as I would
expect). Getting into the displayed directory /Volume_1 
in the dired gets me there, as exected. The next command, the 
attempted creation of "testdir", fails.  So I can browse fine,
but creating directories does not work (the same happens
when trying to delete an empty directory).

I appended also the error stack of the debugger, to see the different
ange-ftp/tramp function calls.

The version of the FTP server is indicated in the protocol, I
guess. Anyway, the host is a NAS (network attached server, a D-Link
DNS-323) and I cannot login to it, it's accessible basically via FTP (and
samba and UPnP).

OK. Could you, please, run a native test from the command line:

# ftp 192.164.1.4

Provide user name / password as requested. Afterwards, please apply the
following commands which we have seen in the ange-ftp buffer. This is a
test to see whether it is ange-ftp or your FTP server which behaves
unfriendly:

ftp> hash
ftp> pwd
ftp> cd /
ftp> ls -al
ftp> quote mdtm /
ftp> cd /Volume_1/
ftp> ls -al
ftp> quote mdtm /Volume_1/
ftp> mkdir /Volume_1/testdir
ftp> bye

Please show the session listing of all these commands. I suspect it is
the FTP server which runs into problems. Maybe because of this from your
test:

> ftp> pwd
> 257 "/Volume_1" is current directory.
> ftp> mkdir testdir
> 257 "/mnt/HD_a2/testdir" new directory created.

Looks like "/Volume_1" is a link or so, because "testdir" has been
created on another physical location.

Ah. Samba on FAT32 likely. This could explain why the smb based copy
results in shortened file names.

Off topic: looks like it is possible to run native Linux on a D-Link
DNS-323. I did something similar with my Linksys NSLU2, and I'm happy
with it.

[Off topic as well: Yes, I have seen that. Not sure whether I dare to do

it connected in a blink to my noxon internet radio via UNpP AV). The only

Hmm, the same output as in the ange-ftp log. That is consistent. I
wouldn't blame ange-ftp, when your FTP server isn't able to create a new
directory over a link.

Have you tried (in Emacs) to go to "192.164.1.4:/mnt/HD_a2/" directly?
And if it works, is it possible to create a directory there?

Otherwise, an option might be to create directories on your FTP server
outside of Emacs, for example with the FTP client on the shell.
Transferring files seems to work, if I understand you correctly.

I'm not intimate enough with ange-ftp to change the command sequence it
sends over the wire. I fear I would break other configurations then.

tramp/ange-ftp: error in creation of dir's

[Martin Steffen]

Hi, 

I came to use tramp/ange-ftp again. I have ftp access to some storage, and
tramp comes in handy.  Now it seems some erroneous behavior:

    I cannot create directories in dired mode via
    tramp/ange-ftp ("direct-create-directory")

    I am using tramp with tramp-default-method = "ftp"

Otherwise, I can login, copy files etc, only the creation of
directories does not work. The error message is


mkdir /Volume_1/x
ftp> 550 /Volume_1/x: No such file or directory.

     

Note that it's not a problem of missing access permissions. In
the command buffer of tramps, which runs the ftp-session, 
I can type in

     ftp>  mkdir somefolder

and it works ok.
----------------------------
I use emacs-version 22.1.1
      tramp-version 2.0.55
----------------------------


Actually, when looking at the command-message buffer, it seems that during
the ftp-session there is something's going wrong, during directory browsing
(with dired). So, the ftp-buffer complains all the time, that the
respective director is not there (see the protocol below). That's strange,
as in the dired-buffer, it seems to work, i.e., I can browse the directory
tree, open files, change them, and store them back. Only in the ftp-command
buffer, tramp/ange-ftp complains that those directories are not there:


ls -al /tmp/ange-ftp3480Z7F
ftp> 227 Entering Passive Mode (192,168,1,4,207,17)
150 Opening ASCII mode data connection for directory listing.

Any help is welcome. Thanks. Martin
