I've done that, and am about to reboot it... Looks like its working, but I've not yet sshsf mounted the nc_files directory since the reboot, worked as expected though. I made an R-Pi_nc_files directory on this machine, and copied the nc_files directory from The Little Monster to there, and mounted it on the pi with a script made executable and contains this line: sshfs g...@coyote.coyote.den:/home/gene/linuxcnc/R-Pi_nc_files/ /home/gene/linuxcnc/R-Pi_nc_files I haven't setup the key files yet, but when I do, the pw request goes away and I can put that stuff in /etc/rc.local so its all automatic. Not well explained in the sshfs "handbook" is the above syntax: sshfs $user@target:/dir/on/target/ /local/filesystem/mount/point Which might make it clearer. sshfs uses fuser, and the traffic over the cat5 is encrypted, but I've yet to see a noticeable lag from the encryption. unforch, the man page I was reading, when it last locked when I ran into the bottom of the page, is not in the terminals history buffer. One long man page, for motion, I just scrolled both ways on, repeatedly banging on both the bottom and top, didn't phase it.

I believe it did, thank you Mathew. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
