Hej

Jeg har lige installeret openSSH på en ny installeret Redhat 6.2. Det gik
helt fint, men jeg har lidt problemer med at forbinde til serveren.

Min klient, SECURE-CRT (Windows) siger at serveren ikke kan genkede min
publickey. Jeg har ellers kopieret den til /root/.ssh/authorized_keys2

syslog siger:

Jun 10 18:06:54 linux sshd[798]: Received disconnect: 11: Unable to
authenticate using any of the configured authentication methods
Jun 10 18:06:54 linux PAM_pwdb[798]: (sshd) session closed for user root

Min /etc/pam.d/sshd fil ser således ud:

#%PAM-1.0
auth       required     /lib/security/pam_pwdb.so shadow nodelay
auth       required     /lib/security/pam_nologin.so
account    required     /lib/security/pam_pwdb.so
password   required     /lib/security/pam_cracklib.so

session    required     /lib/security/pam_pwdb.so
session    required     /lib/security/pam_limits.so

og sshd -d rapportere følgende:

Er det et PAM konfigurations problem eller et sshd problem ?

PS, jeg er helt ny til ssh og linux, så bær over med mig hvis det er et dumt
spørgsmål

På forhånd tak for hjælpen
