Is there possibility to login into machine at enlisting stage?

[Bashlakov Andrei]

Hi all!

I have a troubles with deploying MaaS rack-controller in network, that has strict access restrictions and non-trivial DNS configuration. At this moment all machines that boot via PXE from dedicated rack-controller stopped at login prompt at enlisting stage. There is no logs on region controller nor errors on machines screens nor any information about this machines in MaaS interface. I've dumped machines traffic and investigate it for any errors like problems in connection establishment, but all connections seems to be fine. Machines successfully get boot images from rack-controller and enlisting script from region-controller. Is there any possibility to login to machines at this state and get any logs from them? Or maybe there is other way to debug this problem?

Well be glad for any advice.
