Nie można zalogować się do zdalnego komputera za pomocą klucza

15

Logowałem się na zdalnym komputerze (muszę zrootować ten komputer) za pomocą klucza. Zarówno moja lokalna, jak i zdalna maszyna jest w wersji F23. Od kilku dni nie mogę zalogować się do tego komputera za pomocą klucza. To prosi o hasło. Oto ssh -vvv:

Aby rozwiązać problem, utworzyłem innego użytkownika, zrobiłem to ssh-copy-idi działa dobrze. ssh -vvvdla tej działającej maszyny jest:

Nie mam pojęcia, dlaczego w tej samej kombinacji lokalnie-zdalnej jedna działa, a druga nie.

EDYCJA .ssh / config dla nieudanego to:

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

Nie ma wpisu ssh / .config dla rudra2, tzn. Działał.

Odpowiedz Paulowi na mojej lokalnej maszynie:

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

W obu zdalnych użytkownikach mam tylko authorized_keys. I oba są identyczne.

Jaka (odpowiednia część) Twoja lokalna ~ / .ssh / config?
Sidhekin,
Najbardziej oczywistą różnicą jest to, że dla pierwszego użytkownika ssh stosuje opcje z /home/rudra/.ssh/config, podczas gdy dla drugiego użytkownika tak nie jest. Więc… pokaż nam te opcje?
Sidhekin,

Możliwy duplikat Jak sprawić, aby logowanie bez hasła działało

Głosuję za tym, aby pytanie pozostało otwarte, ponieważ robi dwie rzeczy: 1) niektóre odpowiedzi pomagają użytkownikowi odczytać diagnostykę generowaną przez szczegółowe flagi, a 2) pokazuje, że nieprawidłowe uprawnienia nie są wyświetlane bezpośrednio w diagnostyce , mimo że stanowią podstawę problemu.

Ten problem różni się od „Jak sprawić, aby logowanie bez hasła działało” ze względu na charakter problemu i jego objawy. Administratorzy nieustannie ślinią się, aby oznaczyć rzeczy jako duplikaty. Miej trochę cierpliwości.

Tu jest. Grupa ma dostęp do zapisu do ~ 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

Tak więc sshd odmawia zaufania plikom w ~ rudra i nie używa ~ rudra / .ssh / author_keys, mimo że jego uprawnienia są poprawne.

chmod g-w ~rudra powinien to naprawić.

Och ... Zawsze robię, llaby sprawdzić pozwolenie, aby to zobaczyć, dlatego nigdy tego nie zauważyłem. Właściwie nie wiem, dlaczego ../pojawia się reż. Ale zmiana uprawnień to naprawiła.

To byłaby -aopcja ls- i dlaczego ls -alFkonkretnie o to prosiłem . … Okej, więc -Ftutaj jest zbyteczna; tylko stary nawyk. ;-)

Twój pierwszy użytkownik przesyła klucz rsa i jest odrzucany.

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

Drugi użytkownik odnosi sukces

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).

Twoje wiersze poleceń są różne, a lokalny plik .ssh / config jest aktywowany dla pierwszego użytkownika dla zdalnego hosta 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

Jakich opcji używasz w pliku konfiguracyjnym?

Wreszcie dwa używane rsakeys wydają się różne.

Pierwszy użytkownik

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

Drugi użytkownik

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

@X Tian: Jakiś pomysł, dlaczego pub został odrzucony? Nigdy nie widziałem pliku ecdsa w .ssh
