Question

我希望通过Net-ssh执行密码更改，此代码似乎挂起了：

Net::SSH.start(server_ip, "user", :verbose => :debug ) do |session|

  session.process.popen3("ls") do |input, output, error|

    ["old_pass","test", "test"].each do |x|

        input.puts x

    end

  end

end

我知道连接是有效的，因为使用一个简单的exec我可以从远程服务器上的ls获取输出，但这会挂起。

有什么想法吗？

调试的最后一条消息是公钥成功。

host = IO.readlines('test1.txt') # full path of servers' list

user = 'username'   # username
  i  = 0

while i < host.length 

  Net::SSH.start(host[i], user , :password => "User pass" , :port=> port) do |ssh|
    ssh.open_channel do |channel|
    channel.on_request "exit-status" do |channel, data|
      $exit_status = data.read_long

          sleep 0.1
        end
      else
        puts "FAILED!!"
      end
    end
    channel.wait
    puts "SUCCESS!!" if $exit_status == 0
    end
  end
i += 1
