Question

我目前的网络设置如下： LocalMachine＆lt; --- SSH ---＆gt;服务器＆lt; --- Telnet ---＆gt;路由器。我试图通过Server从LocalMachine连接到路由器（不能直接连接，服务器充当代理的一种）。 Ruby的net / ssh gem用于与服务器的ssh连接。

require 'net/ssh'


@hostname = "10.16.96.40"
@username = "server_username"
@password = "server_password"

Net::SSH::start(@hostname, @username, :password => @password) do |session|
    session.open_channel do |channel|
        channel.send_channel_request "shell" do |ch, success|
            if success
                puts "user shell started successfully"
            else
                puts "could not start user shell"
            end
        end

        channel.send_data("telnet 192.168.11.201\n")
        channel.send_data("router_username\n")
        channel.send_data("router_password\n")
        channel.send_data("sh ip int brief\n")    

    channel.on_data do |ch, data|
            print data
        end   
    end     
    session.loop
end

脚本连接到路由器。它得到打印输出。但是当预计会被关闭时，会话就会挂起。

当我使用Ctrl + C手动停止脚本执行时，我收到以下消息：

    from 25_net_ssh_channel_shell.rb:9:in `<main>'

知道如何关闭频道/会话并摆脱闪烁的光标吗？

Ruby，net / ssh与代理连接到路由器，通道挂起
