Không thể đăng nhập vào một máy từ xa bằng chìa khóa


15

Tôi đã từng đăng nhập vào một máy từ xa (tôi phải root máy này) bằng khóa. Cả máy cục bộ và máy từ xa của tôi đều ở f23. Từ vài ngày trước, tôi không thể đăng nhập vào máy này bằng khóa. Đó là hỏi mật khẩu. Đây là ssh -vvv:

Tôi đã xóa .ssh, .config.cachetừ xa và làm lại ssh-copy-id, mà không cần bất kỳ sự giúp đỡ.

Để khắc phục sự cố, tôi đã tạo một người dùng khác, ssh-copy-idvà người đó đang hoạt động tốt. ssh -vvvcho máy làm việc đó là:

Tôi không biết tại sao trong cùng một kết hợp từ xa cục bộ, một cái đang hoạt động và cái khác thì không.

EDIT .ssh / config cho lỗi không thành công là:

Host aveta
  User rudra
  Hostname phy-aveta.physics.uu.se
  ForwardX11 yes

Không có mục ssh / .config cho rudra2, tức là đã hoạt động.

Trả lời Paul trong máy địa phương của tôi, tôi có:

tree .ssh/
.ssh/
├── authorized_keys
├── config
├── environment
├── id_rsa
├── id_rsa.pub
└── known_hosts

Trong cả người dùng từ xa, tôi chỉ có authorized_keys. Và cả hai đều giống hệt nhau.

[root@phy-aveta rudra2]# diff .ssh/authorized_keys /home/rudra/.ssh/authorized_keys 
[root@phy-aveta rudra2]# 

Chỉnh sửa 2: Không sử dụng ssh / .config Tôi đã nhận xét phần cho người dùng đầu tiên trong .ssh / config. http://ur1.ca/nzndx là ssh -vvv cho điều đó. Nó vẫn đang hỏi mật khẩu

Chỉnh sửa: Quyền Người dùng đầu tiên ... thất bại

#ls -al /home/rudra/|grep .ssh
drwx------.  2 rudra rudra  4096 Oct 12 14:16 .ssh
$ls -alF .ssh/
total 12K
drwx------.  2 rudra rudra 4.0K Oct 12 14:16 ./
drwxrwxr-x. 36 rudra rudra 4.0K Oct 12 14:30 ../
-rw-------.  1 rudra rudra  394 Oct 10 12:01 authorized_keys

Dành cho người dùng thứ 2

# ls -al /home/rudra2/|grep .ssh
drwx------. 2 rudra2 rudra2 4096 Oct 12 14:16 .ssh
$ ls -alF .ssh/
total 12
drwx------. 2 rudra2 rudra2 4096 Oct 12 14:16 ./
drwx------. 4 rudra2 rudra2 4096 Oct 12 14:14 ../
-rw-------. 1 rudra2 rudra2  394 Oct 11 09:57 authorized_keys

Cái gì (phần có liên quan) cục bộ của bạn ~ / .ssh / config?
Sidhekin

Sự khác biệt rõ ràng nhất là đối với người dùng đầu tiên, ssh đang áp dụng các tùy chọn từ /home/rudra/.ssh/config, trong khi đối với người dùng thứ hai thì không. Vì vậy, chỉ cho chúng ta những lựa chọn?

Tôi đang bỏ phiếu để giữ cho câu hỏi này mở, bởi vì nó có hai điều, 1) một số câu trả lời giúp người dùng đọc chẩn đoán mà cờ verbose tạo ra và 2) cho thấy các quyền không chính xác không được hiển thị trực tiếp trong chẩn đoán , mặc dù là cơ sở của vấn đề.

Vấn đề này khác với "Cách thực hiện đăng nhập không cần mật khẩu" vì bản chất của vấn đề và các triệu chứng của nó. Quản trị viên liên tục chảy nước miếng để đánh dấu các công cụ là bản sao. Có một chút kiên nhẫn.

Câu trả lời:

Nó đây rồi Nhóm có quyền truy cập ghi vào ~ rudra:

$ls -alF .ssh/ total 12K
drwx------.  2 rudra rudra 4.0K Oct 12 14:16 ./
drwxrwxr-x. 36 rudra rudra 4.0K Oct 12 14:30 ../
-rw-------.  1 rudra rudra  394 Oct 10 12:01 authorized_keys

Do đó, sshd từ chối tin tưởng các tệp trong ~ rudra và không sử dụng ~ rudra / .ssh / ủy quyền, mặc dù quyền của nó là chính xác.

chmod g-w ~rudra phải sửa nó

Ồ ... tôi luôn luôn llkiểm tra sự cho phép để thấy điều đó, do đó không bao giờ nhận thấy điều đó. Trên thực tế tôi không biết tại sao ../dir xuất hiện. Nhưng thay đổi sự cho phép đã sửa nó.

Đó sẽ là -alựa chọn để ls- và tại sao tôi yêu cầu ls -alFcụ thể. Không sao, vì vậy -Flà không cần thiết ở đây; Chỉ là thói quen cũ. ;-)

Người dùng đầu tiên của bạn gửi khóa rsa và nó bị từ chối.

debug1: Next authentication method: publickey
debug1: Offering RSA public key: /home/rudra/.ssh/id_rsa
debug3: send_pubkey_test
debug2: we sent a publickey packet, wait for reply
debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,password

Người dùng thứ hai của bạn thành công

debug1: Next authentication method: publickey
debug1: Offering RSA public key: /home/rudra/.ssh/id_rsa
debug3: send_pubkey_test
debug2: we sent a publickey packet, wait for reply
debug1: Server accepts key: pkalg ssh-rsa blen 279
debug2: input_userauth_pk_ok: fp SHA256:xT3VPQUunB3Nv/Pmi6C6Sroc0fa9SlKcQ4d0eF2vxzI
debug3: sign_and_send_pubkey: RSA SHA256:xT3VPQUunB3Nv/Pmi6C6Sroc0fa9SlKcQ4d0eF2vxzI
debug1: Authentication succeeded (publickey).

Các dòng lệnh của bạn là khác nhau và .ssh / config cục bộ của bạn đang được kích hoạt cho người dùng đầu tiên cho máy chủ từ xa aveta:

debug1: Reading configuration data /home/rudra/.ssh/config
debug1: /home/rudra/.ssh/config line 4: Applying options for aveta
debug1: Reading configuration data /etc/ssh/ssh_config

Những tùy chọn bạn đang sử dụng trong tập tin cấu hình?

Cuối cùng, hai rsakeys được sử dụng có vẻ khác nhau.

Người dùng đầu tiên

debug2: key: /home/rudra/.ssh/id_rsa (0x562e17c87070),

Người dùng thứ hai

debug2: key: /home/rudra/.ssh/id_rsa (0x55c98f7eb080),

@X Tian: Có manh mối nào khiến publey bị từ chối không? Tôi chưa bao giờ thấy tệp ecdsa trong .ssh
