FTP FEAT command problem.

#1 Post by bsrinath » 2010-11-18 23:58

Hi All,

I am trying to test FTP restart and recover with REST on a homegrown FTP server. For a FEAT command from FileZilla client, the server responds with the list of extensions supported which includes SIZE and REST, but the FIleZilla log shows:

Code: Select all

Trace: Unexpected reply, no reply was pending.
Is that ok?

I ask this because for a broken file transfer, the FileZilla client never sends a SIZE command and always does an Overwrite even if I select "Resume" from the window that pops up. am I missing any setting in FileZilla? Following is my complete debug log:

Code: Select all

The server doesn't send a well-formed FTP reply. Please read RFC 959 on the general structure of FTP replies.

You can also use https://ftptest.net// to test your server for correctness.

Thanks a lot for that hint. The web based test would require that I put my FTP server on the public domain and I can't do that. Is there a way for me to figure out the problem using some other diagnostic tools? Would wireshark reveal the problem. What am I looking for?

Thanks again for the help.

Code: Select all

Response:   FEAT
This line is too much. Every response from the server MUST begin with a response code. In the case of FEAT the listing of the features must be shifted one char to the right (inserted blank at the start).

A small example from http://tools.ietf.org/html/rfc2389#section-3.2

Code: Select all

   A typical example reply to the FEAT command might be a multiline
   reply of the form:

        C> feat
        S> 211-Extensions supported:
        S>  MLST size*;create;modify*;perm;media-type
        S>  SIZE
        S>  COMPRESSION
        S>  MDTM
        S> 211 END

Thanks "boco"! I fixed that, and now I don't see the problem anymore.

I also wanted to find out, how and when does FileZilla decide to use REST (restart) for an upload. I have enabled "Allow resume of ASCII files". In such a case does it try to use REST whenever there is a broken connection for upload provided extension features like SIZE and REST are supported by the server?

Thanks again!

If the server advertises Resume support through the FEAT response, FileZilla makes use of it. For uploads, APPE support would also do.

Great! Thanks for this info! Does it prefer one over the other?

Since version 3.2.8.1, it favors REST over APPE if the server has REST STREAM support.

Is it possible for me to obtain any design documents for how REST is implemented in FileZilla client.

Looking at the debug logs, I can't figure out on a broken upload, how does FileZilla determine what size should it RESTart from? Any ideas?

FileZilla looks at the size of the remote file. Either it knows it from a previously obtained and cached directory listing that has not been invalidated by some other operation or it sends the SIZE command to obtain the actual size.
