new(host = nil, user_or_options = {}, passwd = nil, acct = nil) public

Creates and returns a new FTP object. If a host is given, a connection is made.

options is an option hash, each key of which is a symbol.

The available options are:

port	Port number (default value is 21)
ssl	If options[:ssl] is true, then an attempt will be made to use SSL (now TLS) to connect to the server. For this to work OpenSSL [OSSL] and the Ruby OpenSSL [RSSL] extensions need to be installed. If options[:ssl] is a hash, it’s passed to OpenSSL::SSL::SSLContext#set_params as parameters.
private_data_connection	If true, TLS is used for data connections. Default: `true` when options[:ssl] is true.
username	Username for login. If options[:username] is the string “anonymous” and the options[:password] is `nil,` “anonymous@” is used as a password.
password	Password for login.
account	Account information for ACCT.
passive	When `true,` the connection is in passive mode. Default: `true`.
open_timeout	Number of seconds to wait for the connection to open. See Net::FTP#open_timeout for details. Default: `nil`.
read_timeout	Number of seconds to wait for one block to be read. See Net::FTP#read_timeout for details. Default: `60`.
ssl_handshake_timeout	Number of seconds to wait for the TLS handshake. See Net::FTP#ssl_handshake_timeout for details. Default: `nil`.
debug_mode	When `true,` all traffic to and from the server is written to +$stdout+. Default: `false`.
