The authorized +keys file location is set at the SSH daemon configuration file. +The default location is /etc/ssh/authorized_keys, so: + +[root@clusterhost]# scp /root/.ssh/id_rsa.pub root@alterpath:/tmp + +login to the TS/ACS/KVM box normally and append the public key. + +# ssh root@alterpath +Password: .... + +[root@CAS root]# cat /tmp/id_rsa.pub >> /etc/ssh/authorized_keys + +The following entries must be present on /etc/ssh/sshd_config for the +passwordless scheme to work properly: + +RSAAuthentication yes +PubkeyAuthentication yes +AuthorizedKeysFile /etc/ssh/authorized_keys + +Next step is to test if the configuration has been done successfully: + +[root@clusterhost root]# ssh root@alterpath +[root@CAS root]# + +If it logins automatically without asking for a password, then everything +has been done correctly! + +Note that such configuration procedure (including generation of the key pair) +has to be done for each machine in the cluster which intends to use the +AlterPath PM as a STONITH device. + +------ +Any questions please contact Cyclades support at <support@cyclades.com> +or <marcelo.tosatti@cyclades.com> |
