I'm guessing these are kernel modules. They are never really relevant to my interests.

How can I detach process from a terminal I don't have access to?

Joehillen — Sat, 18 Sep 2010 00:22:08 -0400

I have a server process running in a gnome-terminal at home. I am at work, and I want to detach the process from that terminal and move it to screen without restarting it. Also, I can't use VNC.

Is there a way to do this?

Looking for process manager similar to Services Control Panel in Windows

Kurtosis — Sat, 24 Jul 2010 06:59:46 -0400

Does Linux have a process/daemon manager similar to Windows' Services Control Panel that displays all available servers and services and lets you configure which ones to automatically start on system boot, and which can only be manually started?

I download and experiment with a lot of stuff, from Mumble Server to Nagios, but want a way to turn them off and keep them turned off till I'm ready to use them. I know I can use System Monitor, htop, top, ps -A, kill -9, etc., but none of those seem to provide a way to set the services to default to off, only kill it once it's running.

I restart periodically b/c sometimes I break stuff (still learning) and can't figure out how to fix them besides restarting. Hence would prefer a way to setup the system boot into a minimal state, from which I can enable extra services as needed/wanted.

Is there a (graphical-UI) way to change a process/application priority?

pmarini — Wed, 12 May 2010 08:42:43 -0400

I am familiar with the nice and renice commands on the shell, but is there any graphical method (from the User Interface) to actually launch/run an application at a different priority level so to make it use more CPU than it would normally be allocated to it?
Does the Completely Fair Scheduler introduced with kernel 2.6.23 makes this a moot point now?

how do I find a PID with netstat?

Jasper — Tue, 11 May 2010 16:33:46 -0400

Hello,

I have an ssh server running in daemon mode, I believe, so /etc/init.d/sshd stop wont work. I've tried finding this listening port with netstat (netstat -atx |grep 22) but there are too many processes to list.

How do I find a pid using netstat?
