Reset-Machine-ID(1) General Commands Manual Reset-Machine-ID(1) NAME Reset-Machine-ID -- resets the machine identity state SYNOPSIS Reset-Machine-ID [-H hostname | --hostname hostname] [-M | --skip-machine-id] [-S | --skip-ssh-configuration] [-K | --skip-ssh-key-replacement] [-Z zabbix_server | --zabbix zabbix_server] [-A | --install-zabbix-agent] [--yes-to-all-i-am-really-sure] Reset-Machine-ID [-h | --help] DESCRIPTION Reset-Machine-ID resets the machine identity state, particularly for a cloned VM, to make it appear as a new machine. It performs the follow- ing tasks: * Reset /etc/machine-id, * Reset /var/lib/dbus/machine-id (symlink to /etc/machine-id), * Reset host ID in Debian Popularity Contest configuration file (if in- stalled), * Change hostname, if a new one is provided (--hostname parameter). * Provide hardened settings for SSH client and server. * Create new SSH key pair. The changes are made interactively on request, unless the option --yes- to-all-i-am-really-sure is used. ARGUMENTS The following options are available: -H hostname | --hostname hostname Set the given hostname. -M | --skip-machine-id Do not reset the machine ID. -S | --skip-ssh-configuration Do not make SSH configuration changes. -K | --skip-ssh-key-replacement Do not replace SSH keys. -Z zabbix_server | --zabbix zabbix_server Configure an already-installed Zabbix Agent for a given Zabbix server. -A | --install-zabbix-agent Try to install Zabbix Agent, if necessary, when a Zabbix server is given but no Zabbix Agent is installed. This will add the current Zabbix PPA on Debian/Ubuntu/Fedora systems. Note that a Zabbix PPA may not be available for the used distribution! On FreeBSD, the Zabbix Agent is installed from the FreeBSD Ports Collection. --yes-to-all-i-am-really-sure Create new keys (delete old ones) as well as replace sshd_con- fig and ssh_config without interactively asking for confirma- tion. -h | --help Prints command-line parameters.
