# 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:

# Set the SOCKS version to 4 or 5 based on the version
# of the SOCKS proxy server:
$ftp->put_SocksVersion(5);
# Note: SOCKS4 servers only support usernames without passwords.
# SOCKS5 servers support full login/password authentication.

# Connect and login to the FTP server.
