This PiKVM device has running kvmd-ipmi daemon and provides IPMI 2.0 interface for some basic BMC operations like on/off/reset the server.
WARNING! We strongly don't recommend you to use IPMI in untrusted networks because this protocol is completely unsafe by design. In short, the authentication process for IPMI mandates that the server send a salted SHA1 or MD5 hash of the requested user's password to the client, prior to the client authenticating.
NEVER use the same passwords for KVMD and IPMI users. And even better not to use IPMI. Instead, you can directly use KVMD API via curl. Here some examples:
