Graphical installation is performed through the BeeGFS Admon ("Administration and Monitoring"). It consists of a Java GUI and a beegfs-admon service, to which the graphical interface connects. The beegfs-admon service uses ssh to run installation commands on the other BeeGFS nodes. Thus, passwordless ssh login from the host running the beegfs-admon service to all BeeGFS nodes for user root is required (including the node where the beegfs-admon service is running).
|Note: If you don't know how to configure ssh without password, you might want to have a look at the tool ssh-keygen to create a public/private key pair (without a passphrase) and then use ssh-copy-id to copy the new key to the other nodes, or use your favorite search engine to search for "passwordless ssh".|
