Which processes need to be running???

[Jeepsta]

I have Mandrake 7.2 with absolutely everything installed. The problem is that there seems to be alot of processes running that I dont think I really need to. For example, I have apache running and I dont need that for anything.

I need to know what needs to be running and how to stop all the others from not starting. An NHF would be helpful but I havent found any that fit.

Can anyone lend some advice here.

Thanks,

Zach

SHUT THAT PUPPY DOWN! It's a security risk if you're not running a webserver. Check out the security nhf's on how to shut down the unimportant security risky services linux is consistantly installed with.

Also, if you wanna kill a process, simply type 'ps aux' in a terminal window and that will list all the processes running... find the one you want to kill, and type 'kill <processid>' and viola http://www.linuxnewbie.org/ubb/smile.gif

The problem is that I dont know what processes do what and I figure that they will just start back up again when I reboot. Isnt there a file(s) that control all this.

Keep in mind that I am a newbie here.

In a console or from the command line as root(or su) type ntsysv. Shutdown anything you dont think you'll need ... anything you are not sure of just post here and someone will be able to tell you what it does and you can determine from that if you need it or not. Some essential ones you dont want to shut down are crond, network, random and syslog ... others you may want/need, but most for a desktop workstation you dont need and are nothing but a potential security risk and a waste of memory.

Will that keep them from being started or just shut them down?

Perhaps a better way to look at processes is with pstree, that way you can see which one is parent to what and what killing each will take down with it.

[Jeepsta]

I agree with MkIII_Supra in that I dont know what all these things stand for. Is there an NHF on this subject or another webpage that could lend some advise as to which processes need to be running and which ones are just for ****s and giggles.

Thanx

I run a lean and mean mandrake box. Before posting your PS shots, please shutdown X.. numerous tasks that are not needed will be shown. Also, using Drakeconf there is a button that will let you select which services at boot to use.. I usually turn all off except:

xinetd
anacrond
cups
usually I turn off all the file sharing things, but they are good if you are sharing with a windows comp.

Also, edit inetd.conf and place a # before each service you dont need to use.. none are vital. If you have more questions post a revised PS without X running.

The Startup Services{/i] in [i]DrakeConf are really usefull in Mandrake. Also a mouseover will give a bit info so you might make an intelligent guess on what you need. I personally shut off all server stuff but network.

Here (http://www.mandrakeuser.org/admin/adaemon2.html) is a list of services in Mandrake.

Here (http://www.mandrakeuser.org/admin/adaemon1.html) is a bit more info on your daemons.
www.mandrakeuser.org (http://www.mandrakeuser.org) has a lot of helpfulstuff for, you guessed it, Mandrake Users. Other distros can benefit from it as well, but it definately is Mandrake centric.

Thanx for the help guys. I will look around and read up on those services.
