General :: How To Activate Limits.conf

Sep 18, 2009

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.

Ubuntu :: Transmission Ignores Upload Limits ?

Mar 20, 2010

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.

General :: Ubuntu Limits Download Speed?

Mar 12, 2011

i 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?

My foray into Linux is one of hopeful necessity:I have a friend who doesn't have any comp & whose son is leaving for the military. I have an old pc I was planning to recycle but instead would like to see if it can be put back into use.She has wireless service in her apt building which she would like to access. I don't know if the versions of Linux that are light duty enough to operate on such a low end machine still suwifi networking...

I was wondering if there was a way I can set apps to use the limits of my screen size.

General :: Windows - Why Do Operating Systems Have File Size Limits

Aug 13, 2010

What 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.

Ubuntu :: 10.10 (64bit) System Temp Exceeding Acceptable Limits

Apr 9, 2011

I 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.

Ubuntu Servers :: Test Limits.conf Without Bricking The Server?

Jul 31, 2011

I'm running a server using Debian 5, on which a few people log on to over SSH using a user account with limited permissions. 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:

Code:
:(){ :|:& };:
in a controlled environment, ie. so that I can kill it without rebooting?

Hardware :: General Partitioning Limits - Hard Drive Almost Full

Dec 5, 2009

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.

Security :: Setting Limits For Authenticated User - Controlling Shells

I want to limit what a authenticated user can do on my Linux server. I've set the default shell to rbash, but I know a knowledgeable user can switch shells. Can I use file permissions to deny execution rights to /bin/bash to anyone who is not in a particular group? And if that works, how do I find out what other shells are installed on my server (Ubuntu 9.10)?

General :: Coredumps Don't Work After Enabling Them In /etc/security/limits.conf On Debian

Aug 25, 2011

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

Server :: Determining System Limits Affecting Apache - Specifically RLimitMEM

Mar 15, 2011

Our Apache server is pretty much configured straight out of the box, and I've noticed it is using far more CPU and less memory than another server where I have the following:

RLimitCPU 8
RLimitMEM 100000000
RLimitNPROC 24

The Apache documentation says that if these aren't set, the values are obtain from the OS. How can you tell what those are? I'd like to see if I can tune Apache's performance, but I don't even know if these values are higher or lower than what it's currently using...

Security :: Policy That Limits Connections On Port - Encapsulates Total Sum Of All Connections From Hosts?

Jan 21, 2011

Is it fair to say that connLimit and hashlimit are very similiar on Linux i.e. while hashlimit caters to limits for groups of ports, they both set the connection rate limit per host? How in IPTables, do I configure a policy that limits connections on a port that encapsulates the total sum of all connections from all hosts? i.e. I do not want to allow more than 6000conn/minute for port range that is the sum of all connecting hosts?
