General Linux?

[Knute Johnson]

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?

Thanks very much,

Neither my F7 test 4 box nor my FC5 server box have man screen.  Just 
'No manual page found'.  I did find a reference on a FreeBSD box that 
I have a shell account on though.

Thanks again,

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?

Thanks one more time :-) and sorry to be such a blivet.

It works with PuTTY.

That is interesting. What would you expect it to do?

CTRL ALT F1, etc., are separate logins.  So you may have to run multiple
PuTTY clients.  Alternatively, perhaps there's a way of configuring it
to change what listens to the keyboard (what it pays attention to, what
it passes through for the remote end to use).

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.

Freenx and the free cross-platform NX client is the way to go for remote 
access to a GUI desktop - although the X vnc module can be handy if the 
desktop you want is the one already running on your console.

Screen was installed by default on all my systems. I guess you'll have 
to yum it.

yum install screen

Yah, you kinda have to install it.

You are right, once you install it it works great!

Thanks very much for all the help.

Does your system have screen installed. What does : which screen
return. man screen exists if screen is installed.

The screen command can help here.

man screen

Use the "screen" command.  In essence you would ssh to your target 
machine, issue the screen command, run your command, detach from 
the command by using the "<CTRL-a>,d" sequence, then exit from the 
target machine.  Later you could ssh to your target machine, issue 
the "screen -list" to see your detached session(s) and issue the 
"screen -r <desired-session>" to reattach to the previously running 
session.  See "man screen" for more details.

Or, if you'd rather do this in a GUI where you can see more than one 
open window at a time and the only reason you don't is that ssh works 
better over slow connections, try freenx and the NX client that you can 
download from http://www.nomachine.com.  This lets you start a whole 
desktop that you can suspend and reconnect and it works very well over 
remote connections.  You can, for example, start a bunch of things in 
different windows (perhaps even xterms ssh'd to a bunch of other 
computers), suspend the session, then reconnect from a different place 
(and perhaps a different client platform) and pick up with everything 
still running.  And it can work where only ssh is allowed in.  The 
initial start-up on a new connection is slower than screen of course 
since it has to draw the GUI screen, but it is very snappy after that 
and you can see all of the desktop windows at once if you were doing 
more than one thing, where with screen you would have to switch among them.

Use screen.
