We want to know following :
1) What is the difference between rtprio and priority in limits.conf?
2) How to apply changes in values of limits in limits.conf?
3) What is the value system takes if it is not set in limits.conf?
4) What is the max/ideal value of each parameter especially priority?
I have the following inside /etc/security/limits.conf(I have specified root separately because * will not include it.)
user2 - core unlimited
* - core 0
root - core 0

I would like to limit any process from using more than 500 MB of RAM. AFAIK this is done using RSS in /etc/security/limits.conf but the process called gnome-panel apparently is using 618436 kB of VmRSS. How can this be ?

I've set limits in limits.conf but they don't seem to be having an effect (the easiest to test is maxlogins). Do I need to do something to enable the limits?:wqEDIT: old postI know you can have file system quotas, is there any way to set a similar quota for CPU usage for particular users so that they can't hog all the system resources (either intentionally or accidentally)?A preliminary Google search is suggesting it's not possible, but I can't believe thatOk, limits.conf and pam... I used bad search terms apparently. Now I just need to figure out how to use this stuff, but that shouldn't be an issue.

Basically I want to make sure they can't run things like fork loops as a lot of bad stuff would happen were the server to hard reboot.So, how can I test what something like this will do:

I have some init scripts that launch some daemons that I wrote. I want Linux to generate a coredump anytime something crashes. I activated coredumps in /etc/security/limits.conf by adding the next line:
* hard core 100000 After rebooting, I run ulimit -a and I can see that coredumps are not activated: > root@computer:~# ulimit -a > core file size (blocks, -c) 0 First, I checked if there is any file script on my system that deactivates coredumps (greping ulimit -c 0 ), but I didn't find anything so far.
Then, I created a bogus c program..to double check if it's working, and I can confirm that it's not. The program is this

According to man syslog.conf "You can specify multiple facilities with the same priority pattern in one statement using the comma (``,'') operator. You may specify as much facilities as you want. Remember that only the facility part from such a statement is taken, a priority part would be skipped."
Can someone confirm that this statement means that kern.!=debug is ignored in the first part because it's priority is not the same as the trailing facilities ending in .none?

View 3 Replies View RelatedI've been scanning the apache2 docs for the past few days and have not come up with an answer my following issue:
In my httpd.conf file, at the very end, I have the line
Include conf/vhosts/vhost_*.conf
However, when I run apache checkconfig or try to start apache, it gives me the error:
httpd: Syntax error on line 993 of /etc/httpd/conf/httpd.conf: Could not open configuration file /etc/httpd/conf/vhosts/vhost_1.conf: Permission denied
It appears as if the Include line is correct - in terms of it grabbing the first virtual host conf file. However, I'm confused on the permissions. the /etc/httpd folder is owned by root:root, as are the subfolders. As a test, I chown'd the conf/vhost folder combination and all the vhost files to apache:apache to see if that made a difference, and it appeared to make no difference at all. The log files don't contain anything (assumed because apache isn't starting). If I place the contents of the vhosts in a singular vhosts.conf it works - with the permissions set to root:root. I'd like to avoid having to use one vhosts conf for the configuration I'm trying to achieve - as it would make my life a lot easier.
phpmyadmin files are in usr/share/phpmyadmin but i cant find anything in my apache2.conf or httpd.conf files that point to that directory.How do I find the route taken from the Server root "ServerRoot "/etc/apache2"" to the phpmy admin files.

View 5 Replies View RelatedI have used nVidia my entire linux life (about 5 years clean and sober from M$). Recently, I have switched over to an ATI Radeon HD 5550 card. After many trial and error setups, I finally got the resolutions and screens set properly with a xrandr command, which I have now added to a shell script in ~/.kde4/Autostart. It has worked for me for a while now, but I really would like to get it set in the xorg.conf.d files so that I don't have to wait that extra few seconds after login for the screens to fix themselves.
Is there an easy way to take what xrandr does and export it to the xorg.conf.d files? If my video card recognizes my default monitor as DFP2 and the tv that I only sometimes use with this computer as DFP1, how can I ensure that the login screen for openSUSE/KDE4 appears on my default screen (an issue that drove me nuts a few months ago when I tried Ubuntu to see what all the fuss was about)?
My xrandr command that I use to fix it all is:
xrandr --output DFP2 --auto --pos 0x0 --primary --output DFP1 --auto --right-of
I am using the proprietary Radeon driver from the ioda repository. DFP2 is a monitor which has a optimum resolution of 1920x1200, and DFP1 is an 1080p HDTV. I can not reverse the output plugs for the screens even though my monitor is an HDMI monitor because I use the actual HDMI port on the video card to output audio to the television and the other plug is a DVI that I convert to HDMI for the monitor.
Today I noticed, that despite a 1kb/s limit upload being set i was seeding at an unlimited bandwidth, it had been running for 3 hours wasting about 300mb.
I had never seen this before, however 10gb mysteriously disappeared from my 25 quota last month as i dont mind seeding things at 1kb to help people get the missing bits. My 25gb costs me $100 with the larger package being $160 so i dont have much choice but to be stingy.
how to check the print quota status on print server?
View 1 Replies View Relatedi realised that although before when i had windows7 my relative download speed was around 5.0 MB/s ( i have a 50MB virgin connection)now with ubuntu 10.10 im limited to only 2.8MB/s or somewhere around there.
First i tested my wireless speed on another laptop (with windows 7) on the same network and the speed was as i said around 5.0MB/s sometimes even more. So i thought it was only chrome that i was using at that point.However, this download speed limitation appears in jdownloader as well as in firefox and i guess the whole system.
SO im wondering if there is any way to set up the speed limit on the system and if there is, how should do i go ahead with this change,through the terminal or through preferences?

View 1 Replies View RelatedWhat limits a file to have some maximum size depending on the Operating System? I do not exactly understand this. If you have the storage space, what else can be the limitation? You should be able to store as much data as you want the way you want (even in a single file) unless you run out of storage space.
View 5 Replies View RelatedI recently installed Ubuntu 10.10 (64bit) on my laptop (Toshiba satellite L300 64bit) and have since had horrible issues with the machine overheating. When the system is idle, the temp is decent, a bit warm maybe. If I start browsing the Internet, temp goes way up. I cant watch more than 1 and a half minutes of a ..... video without the system's temp exceeding acceptable limits, and shutting itself down. I have tried both the 32 bit and 64bit versions of ubuntu 10.10, as well as a 64bit version of 10.4. same overheating issues with all of these.
I am 99.999999 percent sure that it is an issue with my laptop's cooling fan, as although it appears to be spinning, it is so quiet that I would think it was off completely if I were to not tilt the laptop back and check to see if it is spinning. Also, the speed of the fan does not change, regardless of the machines temp. Even before it shuts off because of extremely high temps, the fan is still running at that same speed. I am currently downloading fedora 14, a different linux distro, to see if there is any difference.
My friend and I were discussing partitioning and we disagreed on repartitioning when the drive was full. How full is too full before partitioning will mess up your file system? I've partitioned before but it was only after the OS was installed, so only about %5 of the drive is being used. I read that 90% or more is too much. My friend claims it doesn't matter, and you can repartition even if the drive is 95%+ full.
