Cấu hình ssh truy cập bị từ chối
Em chào các anh chị trong diễn đàn ạ! Em muốn hỏi là vì sao mình cấu hình SSH rồi, mà một thời gian sau nó không cho vào, nó báo là "% Connection refused by remote host" vậy có câu lệnh nào để có thể truy cập không? mỗi lần như thế em vô router rồi tạo crypto key mới thì lại truy cập được?
