Tôi đã gặp sự cố khi xác thực máy khách macbook air của mình bằng ssh để kết nối với máy chủ Raspberry Pi. Có bất cứ đề xuất nào về lý do tại sao điều này không hoạt động?
Những điều tôi đã thử:
- Tạo khóa ssh và sao chép khóa chung vào
~/.ssh/authorized_keysthư mục của máy chủ - Đã bật chuyển tiếp cổng sang cổng 777 (sử dụng cổng đó cho SSH)
- Thiết lập quyền trên máy chủ của tôi cho
~/.sshvà~/.ssh/*thư mục - Đã bật RSAAuthentication và PubkeyAuthentication trong
/etc/ssh/sshd_configtệp máy chủ của tôi
Nhật ký ở phía khách hàng:
