But I remember a coworker a few years back who kept the x-server on his Sun Workstation open and someone mistypes an IP number and he got some one else' windows on his screen. Who was more at risk? Can't say. X-11 forwarding is not a good way to do your banking but in a small shop it sure is better then having a dozen screens and terminals I have a Pi3 here and a 4th gen iPad. Goal now is to put X11 on the iPad and use it as a display for the Pi3 I also have a Synology NAS. The operating system for the Pi3 is going on the NAS. So there will be NOTHING connected to the Pi3, not even an SD card. Just power and GPIO. With zero local storage backup becomes a non-issue and on the NAS I can set things up so that it keeps all the old versions of every file. I can "un-do" changes going back months and years. All the files are mounted to all the computers I own so I never have to log into a Pi3 to change a config file It is SO much faster to work with a Pi if you never have to flash an SD card and never have to log into it to make changes and if a change does not work as expected, just set the files timestamp backward to put it back the way it was I think it is a mistake to use a Pi3 as if it were a PC. They make sluggish and not so great PCs but are pretty useful as embedded processors. Try placing ALL of the Pi's files on your big computer. The one in the house that has the nice chair and desk under it.

Using a SD card as a live storage system because that is what you are used to doing with a PC and a disk drive Bater to keep the files on a bigger computer where you can save you old setup using just a "copy" command. Then make the change and test it. Then if it does not work delete the image and rename the saved copy and you are back to where you were. Never make a change to your only good working system image. Make a clone and hack on the clone. I've seen saying you have to decide if the goal is cutting metal or being a pioneer If you want to cut metal use the LAST image of LinuxCNC on a PC with known hardware. > > I'm not certain that it's safe to mix running apt-get and aptitude. > (Never been game to try it to find out.)
