Net::SFTP 无法通过 Ruby 控制台连接

Question

我正在尝试通过 ruby 控制台连接到 sftp 服务器。

代码片段:::

Net::SFTP.start(IP, USERNAME, password: PASS) do |sftp|
.....
end

它抛出以下错误:::::

Net::SSH::Disconnect: disconnected: No Host (7)

    from /Users/venkatesan/.rvm/rubies/ruby-1.9.3-p385/bin/irb:16:in `<main>'

我也尝试使用 Net::SSH.. 得到同样的错误。

但是当我执行 sftp USERNAME 然后提示输入密码时。当我在终端中输入密码时，它连接正确。但是不能单独通过 ruby 代码连接。

有人可以解释一下吗？

Answer 1

终于找到原因了..我给错参数了。它是 user@host。我的参数不正确。

谢谢大家
