Googling a bit it does seem that the T105 lacks a BMC :-( Earlier cheap servers from dell (sc1435 for example) did have it... > How would I access it if it were available? > I see a large number of BMC-related ports in /etc/services , > but none of them seem to be active on my server. The BMC is independent from the OS, think a small separate server inside your real server. If a server has one you access it in one of the following ways: * service ipmi start, local access (requires OpenIPMI kernel driver support) * via LAN to a dedicated management ethernet port on the server * via LAN to a shared ethernet port on the server The LAN access way depends on the BMC having a connection to an ethernet port and a working TCP/IP configuration. /Peter
