Is it an HTTP proxy server ? If so, the answer depends on the type of
authentication method requested by the server.

If you want to do HTTP through an authenticated proxy, you should be using
System.Net.HttpWebRequest. It handles proxy and server authentication. You
just need to provide credentials.

Hi Feroze
I want to connect to my FTP Server through the authenticated proxy server. My application works behind the proxy when there is no authentication enabled at the proxy server. I am unable to pass the authentication to the socket once the proxy server is authenticated.

Manish.

Hi HuangTM
I have a eval version of CCProxy as a proxy server installed.

My core problem is :

How to create a socket to connect to this proxy server when the proxy server is set for authentication
The problem is the Socket class of .NET does not provide me any methods or properties to be set for authentication

Regards
Manish.

Hello Manish,

In .NET, I suggest that you can use WebRequest and its derived class which
supports proxy to communicate to your FTP server. also take a look on the
www.gotdotnet.com site.

There is a sample at
http://www.gotdotnet.com/userfiles/Feroze/ftpclient.zip which provdes a FTP
client class derived from WebRequest and supports Proxy. Please take a look
at it.

Hope this helps.

Hi HuangTM
Thanks for the link that you have sent regarding the sample code.
I tried to run the code behind the proxy server with the following command line arguments

-uftp://64.235.50.69 -pntserver:2121 -v -kutestroxy -kptestuser:tes
1. ftp://64.235.50.69 is my ftp server
2. ntserver is my proxy server
3. 2121 is the port mapped at my proxy server for FTP
4. "test" is my ftp server's username
5. "proxy" is the password of the ftp server
6. "testuser" is the username of the proxy server to connect to
7. "test" is the password to connect to proxy server

I am not able to connect still to my FTP Server with the above arguments
Some times the application hangs or else I get the error message saying "Couldnt open passive data connection. FTP protocol Error..... Status:500 Description:must be connected to remote server."
I also tried to look into the code but was not clear with code to establish the connection to the proxy Server
Can you please help me out as to where the username/password of the proxy is passed to the socket while connecting to the proxy Server. Also please can you explain me what the "ServicePointManager.FindServicePoint" method does. I tried to read this documentation in MSDN but was not clear with the same

Thanks and Regards
