// The SOCKS hostname may be a domain name or 
// IP address:

// Set the SOCKS version to 4 or 5 based on the version
// of the SOCKS proxy server:
sftp.SocksVersion := 5;

// Note: SOCKS4 servers only support usernames without passwords.
// SOCKS5 servers support full login/password authentication.

// Connect to the SSH server.  
// The standard SSH port = 22
// The hostname may be a hostname or IP address.
