Hello,

i have a problem with a file-upload over FTP from a Raspberry PI (OS: Paspbian) using libcurl to a Windows 7 PC. If I use Filezilla instead of curl the fileupload is possible.
can somebody help me?
Windows File is disabled.

Thanks for you support.

FTP-Client Code on the Raspberry Pi:

#include <stdio.h>
#include <string.h>

#include <curl/curl.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <string.h>
#include <fcntl.h>
#include <errno.h>
#ifdef WIN32
#include <io.h>
#else
#include <unistd.h>
#endif

int main(void)
{
  char filePath[] = "/home/pi/LogFiles/Logfile.txt";
  struct stat fileInfo;
  curl_off_t fsize;
  FILE *fp = NULL;
  CURLcode err;
  struct curl_slist *headerlist=NULL;
  CURL* handle = NULL;

  static const char buf_1 [] = "RNFR "; //UPLOAD_FILE_AS;
  static const char buf_2 [] = "RNTO "; //RENAME_FILE_TO;

  stat(filePath, &fileInfo);

  fsize = fileInfo.st_size;

  fopen(filePath, "r");

  curl_global_init(CURL_GLOBAL_ALL);
  handle = curl_easy_init();

  headerlist = curl_slist_append(headerlist, buf_1);
  headerlist = curl_slist_append(headerlist, buf_2);
  curl_easy_setopt(handle, CURLOPT_POSTQUOTE, headerlist);
  curl_easy_setopt(handle, CURLOPT_VERBOSE, 1L);
  curl_easy_setopt(handle, CURLOPT_UPLOAD, 1L);
  curl_easy_setopt(handle, CURLOPT_FTP_CREATE_MISSING_DIRS, 1L);
  curl_easy_setopt(handle, CURLOPT_PORT, 21L);
  curl_easy_setopt(handle, CURLOPT_URL, "ftp://Nutzer:1234@192.168.70.42/logfile.txt");
  curl_easy_setopt(handle, CURLOPT_INFILESIZE_LARGE, (curl_off_t) fileInfo.st_size);
  curl_easy_setopt(handle, CURLOPT_READDATA, fp);

  err = curl_easy_perform(handle);

  fclose(fp);
  curl_slist_free_all(headerlist);
  curl_easy_cleanup(handle);
  curl_global_cleanup();

  return 0;
}
