    //  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:
    sftp.put_SocksHostname("www.mysocksproxyserver.com");
    sftp.put_SocksPort(1080);
    sftp.put_SocksUsername("myProxyLogin");
    sftp.put_SocksPassword("myProxyPassword");

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