[...] the ipmi kernel module allows interfacing/communicating with the 'local system', which is nice, unless the kernel went bonkers. You can - after some configuring(*) - connect from another host via something like: ipmitool -A MD5 -H <remote-host-ipmi-module-ip-address> -U root -I lanplus sol activate and get the remote host console, or do a power cycle: ipmitool -A MD5 -H <remote-host-ipmi-module-ip-address> -U root power cycle danny *: you need configure/enable the bios/drac.
