SOCKS4 and SOCKS5 Proxy for FTP

See more FTP Examples

Demonstrates how to connect to an FTP server through a SOCKS4 or SOCKS5 proxy. Both SSL/TLS and non-secure FTP communications may use SOCKS4 and SOCKS5 proxies. C#

bool success = false;

//  This example requires the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

Chilkat.Ftp2 ftp = new Chilkat.Ftp2();

ftp.Hostname = "ftp.example.com";
ftp.Username = "login";
ftp.Password = "password";

//  To use a SOCKS4 or SOCKS5 proxy, simply set the following
//  properties prior to connecting:
//  The SOCKS hostname may be a domain name or 
//  IP address:
ftp.SocksHostname = "www.mysocksproxyserver.com";
ftp.SocksPort = 1080;
ftp.SocksUsername = "myProxyLogin";
ftp.SocksPassword = "myProxyPassword";
//  Set the SOCKS version to 4 or 5 based on the version
//  of the SOCKS proxy server:
ftp.SocksVersion = 5;
//  Note: SOCKS4 servers only support usernames without passwords.
//  SOCKS5 servers support full login/password authentication.

//  Connect and login to the FTP server.
success = ftp.Connect();

//  Change to the remote directory where the file is located.
//  This step is only necessary if the file is not in the root directory
//  for the FTP account.
