Re: [time-nuts] lady heather on headless linux box

[Douglas Bercich]

Disclaimer: my only experience with LH is on a Windows box, but I have a lot of 
experience pushing bits around on Unix platforms. So, here goes the 5000’ 
overview...

On the LH box:
It can be headless, but needs all the X11 dependencies that make LH work; 
supporting libraries, etc. it does NOT need an actual X server or GUI 
installed. 

On the remote box:
You need an X Server installed and obviously graphical capability. Then the 
procedure - generally - is to ssh into the LH box with X11 forwarding enabled. 
Then you execute LH and it’s display shows up on the remote box. There are 
security details with this; you’ll probably need to type a command to allow the 
LH box to connect to your X server. 

There are other ways of making the connection using xdm and such as well. It 
really depends on what exactly you’re dealing with.

Re: [time-nuts] 1 PPS 50-ohm driver

[Douglas Bercich]

I was looking but can't find a V/div anywhere on that. Maybe my old eyes or not 
enough coffee. 500mV?
