OK, we've discussed two distinct configurations and that wasn't clear. Friday I reinstated the old configuration and checked just now that carnot is still running. Click here ==> http://142.103.107.138/ . If you don't get the home page, the most likely explanation is disk drive failure. > I thought that you had it on a private network > and were trying to tunnel it onto the public internet. That was the recent investigative configuration. In the old configuration, http://142.103.107.138/ connected through the AT 3612TR was accessible to the public from 2002 until a few months ago. I shut it down a few months back because the disk drives were failing. Powered it up again Friday, but a drive might fail any time. For years I've had a private network with Dalton routing connectivity to Cantor. My objective in the past week was to consider whether the AT 3612TR can be eliminated with routing through Dalton. The private subnet to Carnot is incidental to my study of how the objective might be reached. > And of course carnot isn't on the diagram so I feel I am just missing > the mark here. Carnot and the AT 3612TR being absent from the diagram is a bad deficiency. I'll add them on Tuesday or Wednesday when back at work. The AT 3612TR is between dalton and the Internet. Carnot is connected to the AT 3612TR beside Dalton. > What is carnot's first card's address and which wire is it hooked to? It has only one interface. In the old configuration the address is 142.103.107.138 and it is connected to the AT 3612TR. > If carnot is already on 142.103.107.138 then why does it need a > private address ... The primary objective is find whether the AT 3612TR can be eliminated by routing through dalton. The private subnet to Carnot was part of my study of whether and how this objective might be reached. Typically, a Linux router has private subnets. > ... and what looks like an openvpn point to point link > between it [carnot] and dalton? As you said a little earlier, carnot is not on the diagram. The tunnel is between dalton and joule and has no relevance to my present objective. The scanned image from a penciled sketch isn't good but zooming bigger will help.

That idea helps. I thought of another question, probably more directly relevant to my objective. Will post it with subject "Linux hub". Thanks, ... Peter E. -- VoIP 7785886232 is gone.
