~/.ssh adresář a 600 na ~/.ssh/id_rsa (privátní klíč). Pokud nepomůže, zkus volat ssh klienta s vobou -v (verbose mode) a pošli výstup.

PermitEmptyPasswords yes
no a přihlášení klíčem bez problému funguje.
PermitEmptyPasswords
When password authentication is allowed, it specifies whether the
server allows login to accounts with empty password strings. The
default is ``no''.
No tak to nehrozi. Sice tam zadne uzivatele s prazdnym heslem uz nemam, ale nahoda je blbec.
/etc/ssh/sshd_config volba PubkeyAuthentication yes. Pak bych zkusil na serveru vrazit veřejný klíč do ~/.ssh/authorized_keys (místo do~/.ssh/authorized_keys2). Nakonec, máte-li na serveru roota (nebo je-li se správcem rozumná řeč), zkusit spustit sshd v debugovacím módu (man sshd) a podívat se, jestli nevyhodí nějaký rozumný výstup.
PubkeyAthentication je povolena.
Zkousel jsem authorized_keys, authorized_keys2 i identity.
sshd. Bez ohledu na to, jak moc (nebo málo) blbá je ta chyba, kterou tam máte, se IMO těžko pohnete, dokud nebudete vědět, co na ty vaše pokusy říká server.
Teda byl, uz sem to udelal slusneji
U klienta jsem vydegeneroval DSA klic, na serveru jsem ho vrazil do ~/.ssh/authorized_keys2Muzete to vice rozepsat?
ssh-keygen -t dsaA vygenerovany .ssh/id_rsa.pub sem prenesl na server do .ssh/authorized_keys
Passphrase sem zadal prazdnounezadal
ssh-keygen -t rsa
cat ~/.ssh/id_rsa.pub | ssh uzivatel@serever "cat >> .ssh/authorized_keys"
$ ssh user@server -v
