Application over an SSH connection

Awatto · 11-09-2003, 08:03 PM

Is there a way I can run an application over an SSH connection, and have it continue to run even when I close the connection (ie, i close putty on my windows machine, and the application stops running on the linux box). I want to run a Counter-Strike server off a linux box which I do not have keyboard access to unless I want to walk down to my brothers house every time I want to start it up. Is there any way I can do this?

I don't know how putty handles this, but I
can do a
<command>&
in ssh, and if I disconnect, and reconnect,
it will still be running...

Cheers,
Tink

Hmm, that sounds exactly like what I want, but Putty doesnt seem to like it. I close the putty window and it just exits the program. What do you use for the SSH connection?

Linux 2 linux .... a simple xterminal ;)

For a non-graphical console app, "screen" is your friend...

# man screen

# screen

# ^A C

# ^A 0

# ^A 1

# ^A D

# screen -list

# screen -R

etc...

If you start a application with the "&" symbol after it it will continue to run after you close the shell, but I think it will stop when you log out. Might try "nohup whateverappyouwant &" and see if that works. nohup means No HangUp.

Do as this:
nohup your_program

It will continue run when u logout.

Hmm, ill try that.

yep yep 'nohup' is your friend just do

'nohup [your app] &' and you are good to go

I know it does work 100% cause i administer linux servers that are 300 miles from where i live that way.

nohup: appending output to `nohup.out'

know how to fix this by any chance while you're on? I admit I haven't read much about it, I'm trying to but can't find much...

do not worry about those files it just redirects output there. delete them once in a while they are harmless. Basically just a log file.

Awatto · 11-10-2003, 03:29 PM

Ok, worked great, now how do I end the program?

Mikhail_16 · 11-10-2003, 03:52 PM

errr

'ps ax | grep "your program" '
or just 'ps ax' for full list

find your program's number from above

'kill [program number]'

or 'killall [program name]'

i recently came across
"pkill" and "pgrep"
check them out quit handy.
i found pgrep very handy as "ps ax | grep <whatever>" always returned the "ps .." as
a match as well - a nuisance in scripts.

Always learning more about linux

looks handy, I'll have to give that a try next time I need to shut the server down

Just read the manuals.
