红宝石的净/ FTP代码未能放说，由于错误的文件(Ruby net/ftp code failing

我有一个失败的这个基本的代码：

  ftpconfighash = open("#{RAILS_ROOT}/config/ftp.yml") {|f| YAML.load(f) }
  config = ftpconfighash[12345]

  ftp = Net::FTP::new(config["host"])
  ftp.login(config["username"], config["password"])

  dir += "/" unless config["dir"].blank? or config["dir"].ends_with?("/")
  remotename = File.basename(filename)
  remotename = dir + remotename unless dir.blank?

  if File.binary?(filename)
    puts "PUTting binary file #{filename} to #{remotename}"
    ftp.putbinaryfile(filename, remotename)
  else
    puts "PUTting ASCII file #{filename} to #{remotename}"
    ftp.puttextfile(filename, remotename)
  end
  ftp.close

我已验证我可以通过FTP服务器，并用手PUT的文件。 我也用IRB通过代码走行由行。 我使用的XML文件作为测试，所以“ftp.puttextfile”是失败的线。 以下是错误：

Net::FTPPermError: 500 Invalid PORT Command.

我听不懂。 我核实，我确实可以把这个文件，但我不能与此代码做到这一点。

我设置ftp.debug_mode为true，这是从ftp.puttextfile命令的输出：

put: TYPE A
get: 200 Type set to A.
put: PORT 10,0,1,20,198,170
get: 500 Invalid PORT Command.
Net::FTPPermError: 500 Invalid PORT Command.

它看起来像红宝石试图运行一个命令，FTP服务器不理解：

PORT 10,0,1,20,198,170

是否有某种方式来抑制命令，还是我失去了什么东西？

Answer 1:

尝试使用被动FTP：

ftp = Net::FTP::new(config["host"])
ftp.login(config["username"], config["password"])

ftp.passive = true
