how can I start a process, logout, and come back with it still running

[LuxFX]

*NIX is pretty foreign to me, but I'm experimenting with my Java programming, and I need to setup a (chat server) process that will stay running. So far I'm using the 'nohup' command and viola - the java job will stay on after I log off (via SSH to my hosting service). But every time I log back in, it shuts down the service. How can I keep the service going, and be able to hop back into it when I log back in?

hope this was clear!

Use nohup command (text from manpage follows):

NAME nohup - run a command immune to hangups, with output to a non-tty

SYNOPSIS
nohup COMMAND [ARG]...
nohup OPTION

DESCRIPTION
Run COMMAND, ignoring hangup signals.

--help display this help and exit

--version
output version information and exit

The software required `Windows 95 or better', so I installed Linux.

thanks d3funct, but I've tried that. the problem was that logging in again killed the nohup process for some reason. I want to be able to re-login and retain the process.

Hi,

that sounds very strange, because logging into your account should not affect your server prog started in a previous session.

Do you use a publicly available server or was it a developement of your own? A server process should not be linked in any way to a "real-user"-session, instead it should be started when the system reaches the corresponding runlevel without user-interaction.

I have no idea of java-programming, but there should be a way of detaching the process from the controlling terminal and putting itself into the background, like a "normal" c-written server-process does.

ciao,

I would be talking to the hosting service - sounds like they're doing something funny as you login. Mike

Actually you want:

nice nohup COMMAND &

where COMMAND is the command you're using to start the process.

Sorry, I think that's a red-herring - I still think you ought to talk to your hosting service. Mike
