NAME

Reset-Machine-ID — resets the machine identity state

SYNOPSIS

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 following tasks:
* Reset /etc/machine-id,
* Reset /var/lib/dbus/machine-id (symlink to /etc/machine-id),
* 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.

-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.

-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.

--yes-to-all-i-am-really-sure

Create new keys (delete old ones) as well as replace sshd_config and ssh_config without interactively asking for confirmation.
