Chung quy thì lệnh này kiểm tra các file đang kết nối máy tính và các thư viện nó sử dụng. Ví dụ dòng thứ 2 thì YahooMessenger.exe đang truy cập địa chỉ localhost:1036 thông qua cổng 1037 (grass-b1dd508cb:1037), các thư viện nó sử dụng là mswsock.dll, WS2_32.dll, nspr4.dll, Flash10c.ocx, -- unknown component(s) --, WININET.dll...

Bác gửi mail hỏi thầy Định đi, ổng dạy CISCO thì chắc chắn phải biết lệnh này.

Thank bác tdat01 nha!... vì mình thấy mấy dòng lạ lạ,,, mình cứ tưởng có tên nào đi nhầm vào máy em chứ.... Để hum nào gửi mail cho thầy Định để biết chi tiết hơn..
