The previous problem was due to the build of pure-ftpd
I compiled the pure-ftpd with the option
--with-tls --with-certfile=/etc/ssl/private/pure-ftpd.pem

The pure-ftpd.pem was generated using the command
openssl req -x509 -nodes -newkey rsa:1024 -keyout \
  /etc/ssl/private/pure-ftpd.pem \
  -out /etc/ssl/private/pure-ftpd.pem

Now I have a client exe in windows where I use libcurl to connect to the
Pure ftp server in suse linux

The options I give in the client are
        curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER,TRUE);
        curl_easy_setopt(curl,CURLOPT_FTP_SSL ,CURLFTPSSL_ALL);
        curl_easy_setopt(curl,CURLOPT_FTPSSLAUTH ,CURLFTPAUTH_SSL);
        curl_easy_setopt(curl, CURLOPT_SSL_VERIFYHOST, 2);
        curl_easy_setopt(curl, CURLOPT_CAINFO,ftpcertFile.c_str());
        curl_easy_setopt(curl,CURLOPT_CAPATH,".");

where the ftpcertFile is the same pure-ftpd.pem which I generated in the
server and copied to the client machine .

Now I am getting this error.

An FTPS URL to port 21, really?

Eh, this server doesn't seem to want to play ftp-ssl at all.

This seems like a server-side problem so you are probably better of asking
in
a pure-ftpd related forum...
