Do you have > dedicated LAN port for BMC ? Yes. But BMC emulate USB keyboard and this is may be lock inside USB system. "ipmi console don't respond" must be read as "ipmi console runnnig and attached but system don't react to keypress on this console". at the sime moment system respon to `enter` on ipmi sol console, but after enter `root` stuck in login in the '*tcp' state (I think this is NIS related).
