Hola, Tinc un contenciós amb el SSH que m'està portant de cap. A veure si algú de vosaltres hi veu la llum.
La cosa és senzilla d'explicar: vull connectar via ssh a un servidor, i vull fer-ho sense password, és a dir amb clau ssh. Sé com fer-ho, i ho he fet altres vegades: Em genero un parell de claus RSA pública/privada, i copio la clau pública al fitxer .ssh/authorized_keys del servidor, però no hi ha manera. SEMPRE EM DEMANA EL PASSWORD. Abans que feu les vostres hipòtesis, deixeu-me dir el següent. - No sembla un problema de permisos dels fitxers, atès que la cosa funciona cap a altres servidors, i els fitxers implicats tenen els mateixos permisos (700 el directori .ssh i 600 els fitxers implicats). - Les claus estan ben generades. He repetit el procés diverses vegades, i amb altres 2 servidors funciona sense problemes. - No sembla cosa dels paràmetres del servidor SSH, perquè me'ls he repassat i no hi veig res estrany o diferent als altres servidors. - AQUESTA ÉS BONA: Si intento establir una sessió ssh per primer cop, l'autenticació per clau falla i em demana el password, però un cop establida, si provo d'establir-ne una segona des d'un altre terminal, ALESHORES FUNCIONA!! És de bojos. Si voleu els logs..., però no hi veig res estrany: Quan no funciona: debug1: Reading configuration data /home/orestes/.ssh/config debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to xx.xx.xx.xx [xx.xx.xx.xx] port 22.
