Wo der ssh-Dämon den Key, bzw. die erlaubten Key sucht steht in /etc/ssh/sshd_config
der Eintrag sollte so aussehen:
AuthorizedKeysFile .ssh/authorized_keys (Wobei hier relativ zum Homeverzeichnis des Users geschaut wird.)
Gruß Axel
also authorized_keys sieht so aus: server2:/var/backup/.ssh # cat authorized_keys ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAIEA7zDdaFUpIv4hOsd3cUzRbJWg7MQcLudaDCHqBDodVSr5bYRB c+to6SZYqdQR0kHK13al8dOfznDXXf4iAVXGA7lJ9ZcnnFDXtqHvwN7su6r8D+0aUokBWFAOeigK HYg1EoFjD/j7Zk5hFOwg0+9UMqsiDSzkwD11b/ST5G9xtNE= backup@h561178 die sshd_config sieht so aus: # $OpenBSD: ssh_config,v 1.19 2003/08/13 08:46:31 markus Exp $ # This is the ssh client system-wide configuration file.
