Logowanie Linux-Linux bez potrzeby podawania hasła ( ssh ).

Logowanie za pomocą uwierzytelnienia za pomocą klucza.

Opis znajduje się tutaj. Aby nie podawać hasła należy w pierwszym kroku algorytmu wcisnąć enter gdy skrypt poprosi o hasło.

W astronomicznym skrócie (wszystko wykonujemy po stronie klienta):

ssh-keygen -t rsa
albo
ssh-keygen

ssh-copy-id -i ~/.ssh/id_dsa.pub username@serwer.wejsciowy

keychain – ciekawy program, trzyma klucze po wylogowaniu (np. dla crona)

Uzupełnienie:

W ubuntu (po stronie klienta) w w/w konfiguracji dostaniemy komunikat: Agent admitted failure to sign using the key. Należy wydać komendę ssh-add.
