nuc5 computer replaced with new model, clean debian9 install

Carlos, Dave:

A new nuc (build name nuc25) has been installed as nuc5 in the control room (was renamed to nuc5). The old nuc was renamed to nuc25 so I could take files off it.

I've tested the kinit script generates a kerberos nuc5 robot ticket, and the dmtviewers are able to obtain data. My new startup script expands and starts the plots correctly. The new machine had its screen saver on, I've manually turned it off. Because it has the same name, the web links to its screenshots are operational.

Reminder, we are fixing the problem whereby one of the dmtviewers segfaults after a random period of time, anywhere from 7 minutes to over a day.

Lower right dmtviewer (3-30Hz) just segfaulted, so problem maybe inherrent with deb9? Perhaps time to downgrade this machine back to deb8 for further testing.

actually there is no segfault dmesg for tonight's crashes. Looks like 3-30Hz dmtviewer has crashed at least twice in the past 5 hours.

Booted nuc5 at 12:39am and everything started fine, but the Upper Displays low-freq seismic DMT Viewer stopped running at 12:53am.
