I'd normally admin the hardware via the DRAC but it's non-functional now. The system won't boot without someone there plugging in a keyboard and pressing F2 to continue... arrrgh!

I don't know this though. It might be CPU or RAM, both of these can be swapped out, just need to capture the info... arrgh! -- J.

10.3-stable random server reboots - finding the reason
It's not an external vulnerability in the DRAC is it as that seems to be more and more common these days On Tue, 18 Apr 2017 at 15:10, tech-lists <tech-lists at zyxst.net> wrote:> On 18/04/2017 13:34, Kurt Jaeger wrote: > > > 1) > > echo '-Dh -S115200' > /boot.config > > 2) > > vi /boot/loader.conf > > ------------ > > console="comconsole" > > comconsole_speed=115200 > > ------------ > > > > Then: connect it to some kermit session from a different box, > > and write a session log.
