# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

ftp = Chilkat::CkFtp2.new()

ftp.put_Hostname("ftp.example.com")
ftp.put_Username("login")
ftp.put_Password("password")

# 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:
ftp.put_SocksHostname("www.mysocksproxyserver.com")
ftp.put_SocksPort(1080)
ftp.put_SocksUsername("myProxyLogin")
ftp.put_SocksPassword("myProxyPassword")
# 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.

# Change to the remote directory where the file is located.
# This step is only necessary if the file is not in the root directory
# for the FTP account.
