//  To use a SOCKS4 or SOCKS5 proxy, simply set the following

//  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.
