Lấy IP từ clien log faild thì ra kết quả IP Nga:

Có 2 IP cùng lớp mạng thay nhau Brute Force Attack là 213.226.123.99213.226.123.98

Hiện tại nó vẫn đang scan nhưng em đã xóa hết data server rồi!

Trước đó em có cài proxy hàng tàu này vào máy không biết có phải do nó không :cold_face:

việc bạn mở ra thì bị scan là chuyện rất bình thường, câu hỏi đặt ra là tại sao bạn lại mở nó ra ngoài?
khi bạn làm gì đó, bạn cần phải biết, phải hiểu là mình đang làm gì chứ

Em mở port database để em remote access vào database, bây giờ cho dù em nhập đúng password thì DBMS cũng không cho em access.

Em muốn config chỉ cho phép dãy IP VIệt Nam truy cập server, cho em hỏi tìm list IP của ISP Việt Nam ở đâu. Em cảm ơn.

Đây là để từ chiều qua đến sáng nay vào mà nó còn như này, mấy cái scan này ông để mật khẩu đặc biệt mạnh là oke rồi

nên dùng 1 máy chủ trung gian rồi cài tunnel ssh hoặc tương tự để dứt điểm
tất nhiên lúc này con máy trung gian sẽ thành tâm điểm bị brute force
