I probably have 5 or 7 tabs open, su- at any one time.

That makes a lot of sense, doing it that way, but since nfs is working now, I'll likely skip it. Once I get the forward path in nfs set, then I can redirect pcb-gcodes output files directly to the ~/gene/emc2/nc_files/project_subdir on the milling machine, and only be missing one thing. And that is either a stream file editor to manipulate the X<value> in a .bot. file to be X<value + 2.195>, thereby offsetting the file back to the board pocket in the board fixture. sed comes to mind, but apparently has no math functions, only text, so its DOA as a simple solution. pcb-gcode does the "Mirror" function by negating the Xvalues it writes to a .bot. file, but that makes the mirror on the minus side of X0.0 and I need to offset it back to the right so it hits the board turned over on the Y axis and remounted to the fixture. This could also be done if its possible, in the file setup header if a "for the duration of the file" gcode "touch off" could be done without moving the machine itself as long as there is a matching "touch off cancel" so we leave it in a known state for the next run. Actually, moving the machines X to the right by the length of the board in the gcode input, then doing the "touch off" would also get the job done. So the success of that depends on how hard it is to do an in-code touch off. Either way should allow near perfect registration of the top & bottom of the board. Either method would allow correcting this pcb-gcode shortcoming. I got a msg back from the author but he is in school, up to his butt in study alligators and can't get back to it for a while. > If you make a mistake in the passwd file and cannot login anymore, > reboot and use live CD (ubuntu, knoppix, fedora, etc.), to bootup, mount > root partition, edit/fix passwd file and reboot.

Duh, it's past 2pm), the 2nd cup hasn't kicked in yet. :( I've now been searching the package repo looking for a sed-like util that can do the additions. 4 hours wasted and I am only down the the middle of the p's.
