我有这个失败的基本代码：

  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

我已经验证我可以 ftp 到服务器并手动 PUT 一个文件。我还使用 irb 逐行浏览代码。我正在使用 XML 文件作为测试，因此“ftp.puttextfile”是失败的行。这是错误：

Net::FTPPermError: 500 Invalid PORT Command.

我不明白。我已经验证我确实可以放置这个文件，但是我不能用这个代码来做。

我将 ftp.debug_mode 设置为 true，这是 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.

看起来 Ruby 正在尝试运行 FTP 服务器不理解的命令：

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

有什么方法可以抑制该命令，还是我错过了其他东西？

尝试使用被动 ftp：

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

ftp.passive = true
