    // 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.
    String hostname = "sftp.example.com";
    int port = 22;
