Temat: SSH + logowanie za pomocą kluczy
WitamMam problem z połączeniem się z serwerem poprzez protokół ssh. Już od kilku dni siedzę i przeszukuję internet i nie mogę znaleźć rozwiązania.
Potrzebuje nawiązywać połączenie z drugim serwerem poprzez ssh bez podawania haseł. Obecna moja konfiguracja działa, ale muszę podać hasło. Konfigurację oparłem o opis dostępny pod adresem: http://dug.net.pl/tekst/65/ssh___klucze_rsa_(mozliwosc_logowania_bez_hasla)/
Na serwerze z którego nawiązuję połączenie wygenerowałem parę kluczy RSA
ssh-keygen -t rsa -b 4096
Następnie zawartość klucza id_rsa.pub dodałem na serwerze z którym będę się łączył do pliku ~/.ssh/authorized_keys, za pomocą polecenia:
ssh-copy-id
Sprawdziłem, klucz został dopisany.
Niestety, nadal połączenie ssh wymaga ode mnie podania hasła (podczas generowania klucza passphrase pozostawiłem puste).
W logu pojawia się następujący wpis:

Po podaniu polecenia
