Method: Net::FTP#connect

Defined in:
lib/net/ftp.rb

#connect(host, port = FTP_PORT) ⇒ Object

Establishes an FTP connection to host, optionally overriding the default port. If the environment variable SOCKS_SERVER is set, sets up the connection through a SOCKS proxy. Raises an exception (typically Errno::ECONNREFUSED) if the connection cannot be established.
