Marcoinstallkey =============== The utility detects all nodes in the network and install the specified public key in them. This is useful when deploying ssh-based applications such as MPI, avoiding entering the password every time. If run with the -h, a help message is displayed :: > Usage: marcoinstallkey [-h|-n] [-i [identity_file]] [-p port] [[-o ] ...] [-u user]\n Arguments -h, --help show this help message and exit -i [identity_file] Use only the key(s) contained in identity_file (rather than looking for identities via ssh-add(1) or in the default_ID_file). If the filename does not end in .pub this is added. If the filename is omitted, the default_ID_file is used. Note that this can be used to ensure that the keys copied have the comment one prefers and/or extra options applied, by ensuring that the key file has these set as preferred before the copy is attempted. -p [port] -o [ssh_option] -n dry run -u user
