... Mời các bạn khám phá tiếp Tham khảo thêm về một đoạn script khởi động lại ADSL Router và cách dùng autoexpect: http://www.cyberciti.biz/tips/shell-script-to-reboot-dsladsl-router.html  

em ko hiểu lắm, tại sao trên router ADSL này lại chạy được những lệnh của linux 

cho em hỏi sao mà em vào Login :admin nhưng mà ở cái hàng Password: em không gõ được bất cứ chữ nào cả - giống như bàn phím bị liệt vậy nhưng mà khi ấn Enter thi nó báo là "Login incorrect . Try again." sau đó thì em lại nhập bàn phím bình thường....cho hỏi vậy là bị gì ạ? 

Cho emm hỏi thế đối với ZyXEL P-660H-T1 thì làm thế nào để thực thi các lệnh trên máy đó
