Probleem järgmine:
root kasutajaga üle SSH masinasse logimine õnnestub. B masinas on genereeritud dsa key ja saadetud cat'iga C masinasse. Passphrase on tyhjaks jäetud, miska võiks eeldada et ilma paroolita login toimiks. Kui nyyd yritada B masinast C masinasse logida, kysib C masin parooli.
(Sama yhendus toimib A ja B masinate vahel normaalselt, parooli ei kysi...)
Kui proovida ssh root@C -v, annab tulemiks:

C masin on E masina koopia. Kas võib olla probleem ssh confis või PAM confis?
(NB! Paluks reaalset abi ja mitte hala teema yle et root no-password on ebaturvaline jms. Tulenevalt vajadusest on seda vaja ja teiste masinatega töötab. Tegemist sisevõrguga.)
