Is it possible to ssh to my computer, start a command line
program, exit ssh and then come back later and ssh to the same
command line program? How would I do that exactly?
man screen
Well, I've got another hitch, I'm using PuTTY for an ssh client from
my WinXP box. <CTRL-ALT-F?> just rings the bell and prints [1?~.
Will it work with PuTTY or only with a Linux version of ssh?
What you want is 'Ctl-a d' to detach then 'screen -r' to
reattach. (And possibly 'screen -l' to get a list of IDs
if there's more than one.) It can do much cleverer things,
but I've usually found that's enough and I have used it with
PuTTY.
You could always tunnel VNC over SSH of course, but that
may be a bit heavy duty depending on your purposes. It's
certainly more bandwidth hungry.
