Server Optimization

Aea

Please don't give me "That sucks, use that," or "That's not enough bandwidth you n00b," I just don't need somebody telling me my server sucks. Now, I want to optimize my server, I'll give you some specs below...

3.1.1.0 Hlds Unsecure
800 Mhz Duron Cpu
512 MB of ram
256 Kbs upload (stable)
When I get more then 8 people on my server my ping goes from 30 to over 100, obviously caused by cpu/ram issues. I have the 2.4 kernal and I'm running KDE, any hints?

Stop running KDE.

If you can get away with not using the X11 interface, your RAM/CPU load will be dramatically decreased.

I've got to agree here, I use KDE myself on my desktop client and it's great for that. What it's not great for is making servers run faster.

I'd do ps -ef and look at the process list and see what processes you can do without. If it's a standard bloathat install you can remove 50-90% of that crap and run a HLDS server fine.

Also, if you want some better feedback you should also post the cmd line you use to start hlds, the contents of your server.cfg and autoexec.cfg. Withhold any passwords or stuff like that but it'd be nice to know what junk you have running with HLDS. I was running pingboost -2 for a while and that hit the CPU pretty hard. I removed that line at someone elses suggestion and the server was able to handle a few more users.

Aea

Here's my launch command ./hlds_run -game ns +ip
12.254.40.75 +maxplayers 12 +map ns_eclipse

I'm running Metamod, with amx, unstuck pro, and lerklift. I striped down the amx to it's bare necessities <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->

My cpu use is pretty high, any way to shut down KDE while running it?

billcat

uh.. if you're in the kde desktop there should be a logout thingy down at the bottom. If you asking me if you can close KDE and still have the server you started in a KDE window working, I don't think that's possible. I'd shut down the server, log out of KDE and then from the console start HLDS.

Aea

Closest thing I can get is "failsafe" which is still GUI like with a console, anyhow, which are safe to nuke?

notice all that kde crap in your ps output? yep, you are still running KDE. You need to use the logout feature to get all the way out of KDE. Try CTL-ALT-BACKSPACE to hard kill xwindows. The key here is NO GUI!! Use a standard console login and no GUI at all. Yes, we're no longer in MS land.

I'd also shut down sendmail unless you're really doing mail on that desktop.

Aea

Um, KDE will just start over again if I shut it down, and when I try to hardkill GUI it turns off my pc :o

How crucial is the information on the computer at the moment?

I take it that when you installed it, you checked the "Start in GUI Mode" which is a pain.

The "easiest" way is to re-install the machine. Otherwise there are some config files somewhere that control whether KDE starts up or you are left in console mode.

I can't remember off hand where they are, so it may be easier for you to tar and gzip your HLDS files, transfer them to your other computer, and then re-install Linux, then transfer them back.

While you're at it, try another distro of linux that isn't quite so bloated. Suggestions here are slackware, debian, suse.

Aea

Reinstall isn't an option now, I have a match in 2 hours and 30 minutes, and if anybody knows the location, please tell me <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->

Ok depending on your distro you can disable booting into X-windows

If you are in X and want to disable it simpely press CTRL + ALT + F1 and log in as root. then use a
<!--c1--></span><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td><b>CODE</b> </td></tr><tr><td id='CODE'><!--ec1--> kill <pid> <!--c2--></td></tr></table><span class='postcolor'><!--ec2--> where <pid> is the pid of your X server

root 3035 3034 3 00:14 ? 00:00:02 /usr/X11R6/bin/X -auth /var/g

in this case 3035, BEWARE this numberg changes everytime X is restarted
if you really want to hard kill the X server use a <!--c1--></span><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td><b>CODE</b> </td></tr><tr><td id='CODE'><!--ec1-->kill -9 <pid><!--c2--></td></tr></table><span class='postcolor'><!--ec2-->

If you tell me what distro you are using i can tell you how to remove all the other crap including sendmail, cups and rpc services

biomass

If you don't care about X at all you can change the following to boot into console mode instead of the graphical interface. What you need to do is edit a file called /etc/inittab as root. You should find a line there that says
<!--c1--></span><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td><b>CODE</b> </td></tr><tr><td id='CODE'><!--ec1-->id:5:initdefault:<!--c2--></td></tr></table><span class='postcolor'><!--ec2-->
If you change the 5 to a 3 you will make the computer boot into console mode (runlevel 3), you will also see the different numbers you can use described in the inittab file. Hardly anything but 5 and 3 and 1 are used.

It is also possible to manually trigger this while logged in as root byt typing 'init 3' in a console window if you are in the graphical interface mode.

It seems that you are running redhat, is that so ?

If so you can use the chkconfig command to list which services are run at each runlevel and enable/disable them from there.
A printout of 'chkconfig --list' would be more helpful than a ps output actually.

and don't listen to people telling you to reinstall, it should not be necessary. =)

Hi,

I think the best way for you is just simply start your linux-system with "init 3" as a kernel-parameter this will start in console mode with network but without gui. So in your lilo or grub there is normally a menu entry like "linux" or something, this word "linux" is written at a boot-command-line below the menu.. Just write init 3 behind this, so you got "linux init 3".
Of course the other way is to disable xdm, kdm so X won't automatically restart if you kill it <!--emo&;)--><img src='http://www.unknownworlds.com/forums/html/emoticons/wink.gif' border='0' style='vertical-align:middle' alt='wink.gif'><!--endemo-->

Jsut edit the /etc/inittab file


there is a line called default run level...its set at 5 right now, set it to 3 (could be set to 4, they keep changing it)
