At this point, I think I'll use some of /amandatapes spare space to extract the last full, then go find what I need, and copy it back by hand. AIR use dd to feed starting at 32k, to tar xv better yet use dd to get the instructions from the files header which I did, but the final tar's argument was wrong and it errored without creating an output file. So I just fed it to tar x -, and it worked perfectly. Then I used a root mc to copy the 2 trees I needed to a transfer dir in my /home/gene/linuxcnc dir, did a chown -R gene:gene on both of those dirs. Then found /sshnet/picnc was empty, so dropped out of root, cd, then ran bin/mount-machines answering with my pw, which brought that link to life, fired up mc as me, and copied those 2 dirs to /sshnet/picnc/home/pi/linucnc.shut that down and ran linuxcnc picking the normal config, and 20 seconds later I had the same gui I've been looking at for a couple years. So I think I am in business. Just one problem, the grin has pushed my ears a good half an inch to the rear. :-) Thanks for the hand holding, Deb, its both appreciated, and helps keep my train of thought from getting derailed in the minutia. At 84 & still counting, that is very easy to do. Theres's no one else here that both understands what I'm doing, or cares if I do it. Nobody else to talk to IOW. Its past dinnertime here, so I'd better go do something about that. Take care now. Copyright 2019 by Maurice E.
