A qustion about FtpWebRequest & SSL
Dear All,
I am developing an application which uploads/downloads files to a FTP server. My code was working properly until I enabled
SSLinFtpWebRequestobject
===========================
FtpWebRequest result = (FtpWebRequest)FtpWebRequest.Create(URI);
result.EnableSsl =true;
//Set the login details
result.Credentials = GetCredentials(); // sets user name and password and server url
//Do not keep alive (stateless mode)
result.KeepAlive =false;
=============================
Tehn this exception was thrown “The remote certificate is invalid according to the validation procedure”
After searching about this problem I found a hint in this foroum http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=620849&SiteID=1
You can change the implementation of ValidateServerCertificate() to "return true;" which happily swallows any certificate issue, but you should rather investigate what's wrong with the server certificate.
I did it
============================
ServicePointManager.ServerCertificateValidationCallback =newRemoteCertificateValidationCallback(MyCertValidationCb);
//create request
FtpWebRequest result = (FtpWebRequest)FtpWebRequest.Create(URI);
result.EnableSsl =true;
result.Credentials = GetCredentials();
//Do not keep alive (stateless mode)
result.KeepAlive =false;
return result;
}
publicstaticbool MyCertValidationCb(
object sender,
X509Certificate certificate,
X509Chain chain,
SslPolicyErrors sslPolicyErrors)
{
returntrue;
}
================================
but I got this exception:The remote server returned an error: 227 Entering Passive Mode (67,19,157,166,205,136)
Is there any other setting which I shall set in server or client Certificate?!
Any help will be appriciated.
Thanks in advance,
Saeideh
