Baseboard Management Controller is implemented on “enterprise” systems and along with several satellite controllers facilitates access via a platform management system. IPMI is a set of specifications for interacting with these systems. Typically the BMC provides a web interface, but there is also ipmitool which facilitates access over an ssh server running on the BMC.

There was a complexity in that one of the BMCs was remote and was being made accessible via a transparent bridge that had an arbitrary vlan tag set. Maybe its embarrassing to admit, but for these edge devices there was a need to be able to see both ssh (ipmitool) and http (graphical kvm), so these were exposed via wireguard. ...
