FTP server get or put commands do not work

I’ve implemented the HTTP and FTP server using the MDK4.03 and RL-ARM 4.05 in a system based on LPC2468. The system makes use of a flash file system implemented in an SPI flash memory. The HTTP implementation works fine I can download and upload files to/from the file system on the device.
When I tried the FTP server using the Windows command line FTP client utility I can connect to the FTP server, I can get a directory of the file system but I cannot get the files from the embedded file system. What is very strange is that I use the “mget *” command and the utility asks me if I want to get “file1” and I answer ‘y’ but then it says “File Not Found” and the same happens for the other files that were previously stored via the web interface. If I try to use the "put" command the Windows command line FTP client utility accepts the command but does not do anything.
I used another FTP client app, the one from Total Commander and with it I can “put” files into the device but I cannot get them back. Besides Total Commander adds a “\” at the beginning of the file name.
In the “NetConfig.c” I setup 10 TCP sockets, 4 to serve 4 HTTP sessions and 6 for 3 FTP sessions (I read in the TCPnet docs that the FTP server uses 2 sockets per session). I checked with Wireshark what is happening, I see the commands being sent and the responses coming from the embedded device so the TCP side is working. I noticed that the FTP server uses port 21 for command and ports starting with 1025 for data.

What I do not understand is why do I get the “”File Not Found” on get when a “dir” shows the file is there. Where should I look to find the problem? The “FTP_uic.c” is included in the project, the FTP file system access functions are very similar to the ones from the “HTTP_uic.c” .

Any pointer towards solving this problem will be greatly appreciated.

Many thanks,
Doru

Hi Doru,

I believe that i solve the problem, i using 4.13 but i made some changes in the FTP_uif.c
below the code changed for you test, in here now i able to do all operations over FTP runing in the RAM...take a look, was just the (fname+1)...
below:


void *ftp_fopen (U8 *fname, U8 *mode)
{
  /* Open file 'fname' for reading or writing. Return file handle. */
  return (fopen ((const char *)fname+1, (const char *)mode));
}


BOOL ftp_fdelete (U8 *fname) {
  /* Delete a file, return __TRUE on success. */
  if (fdelete((char *)fname+1) == 0) {
    return (__TRUE);
  }
  return (__FALSE);
}


BOOL ftp_frename (U8 *fname, U8 *newn) {
  /* Rename a file, return __TRUE on success. */
  if (frename((char *)fname+1, (char *)newn) == 0) {
    return (__TRUE);
  }
  return (__FALSE);
}

Best Regards

Hi Doru,

{
  /* Open file 'fname' for reading or writing. Return file handle. */
  return (fopen ((const char *)fname+1, (const char *)mode));
}

  /* Delete a file, return __TRUE on success. */
  if (fdelete((char *)fname+1) == 0) {
    return (__TRUE);
  }
  return (__FALSE);
}


BOOL ftp_frename (U8 *fname, U8 *newn) {
  /* Rename a file, return __TRUE on success. */
  if (frename((char *)fname+1, (char *)newn) == 0) {
    return (__TRUE);
  }
  return (__FALSE);
