I noticed that firefox sometimes uses a lot of memory. Can something like setrlimit be used to control it? I tried to use it on the command line, but it didn't work.
View 1 RepliesI'm considering setting up a virtual machine running Windows, with Ubuntu 10.10 as the host OS, for those cases where I have a Windows-only program.I understand that using a VM will lose some performance, but are there other limitations to what the OS in a virtual machine can do compared to "running on bare metal"?
For example:
Can a VM play games, like Dragon Age Origins or Civilization V? (Possibly with poorer framerates and/or lower resolution, but does it play at all?) Can a VM rip DVD/Blue-ray using AnyDVD or similar Windows program? Can a VM handle new hardware that requires dedicated drivers, but the drivers are only available for the OS running inside the VM? (Ex. graphics card, digital camera, card reader for smart card authentication.) Is it possible to say anything about "general limitations" of VMs, or is this wholly dependent on the specific VM?
I am working on Fedora, I am trying to figure out if there is any way we can set limitations/rights to linux desktop, so that we can control which things user can access, like if i dont want user to have access to kde control center, and should not change the settings in it, or disable changing wallpaper,or disable changing screen saver. How that can be done in linux?
View 3 Replies View RelatedI have a network of 100 machines, all with ubuntu Linux. Is there a limit to the number of machines that can connect to one single machine (at the same time)? For example, can I have 99 of my machines maintain continuous ssh connection to the 100th machine? Can I have every one of my machines (every one of the 100) maintain a continuous ssh connection to all other 99 machines? How much memory does each such a connection take?
View 2 Replies View RelatedI'm having a problem with setrlimit() under linux.
If i used setrlimit(RLIMIT_AS) to set a hard ceiling of virtual memory usage first, then request memory more than that, shouldn't i receive a signal like SIGSEGV?
First i tried the command ulimit in bash, which acted as if i called setrlimit(). i tried 3 programs that overflowed the memory limit i set. i though all the programs would be terminated by a SIGSEGV. but the pascal program received SIGKILL; the C++ program got SIGABRT› the C program, SIGSEGV.
I though there maybe something different between setrlimit() and ulimit, so i wrote a program in C++, fork() first, setrlimit() then execv() in the child, and wait(&status) in the parent. but i got the same result.
I was wondering why these could happen, and could anyone tell me how could i deal with them? i mean, how can i judge that the program exited abnormally because it exceed memory limit?
I have the impression that not that many people understand the scope and limitations of GNU General Public License. This is somehow my basic understanding of it. If I take a program covered under the GNU license, first of all I have the right to get the source code. Second, I can modify it at will. Third, I can redistribute it as will too but the new code will necessarily will have the same GNU license. This made me wonder how people actually can charge for software derived from Linux, for instance, Red Hat. Well, my impression is that they really make profit only out of services. In this thread [URL] I think I found a lot of confusion, even from a moderator (not intended to offend). Red Hat is based on Linux and it is necessarily covered under GNU. Somebody probably bought the program from RHE and can make it available at no cost.
Nevertheless, the moderator decided to warn the user. In this article [URL] it says the following:"Our training is not designed to promote vendor lock-in. Though these courses are based on Red Hat Enterprise Linux, the source code for [RHEL] is available to the community via the GPL [GNU General Public License]," said Red Hat spokewoman Leigh Day. This thread [URL] shows yet more confused people. Is there is a glitch in this type of license that prevents programs like RHEL to be redistributed for free? Why their license page doesn't mention GNU license? Or the problem is just that people get overwhelmed by this license and are afraid to be penalized and get paralyzed? By the way, RHEL is just the example. The key question is about the license!!
I need to share some space on my hard disk with my wife, over our home network. I'm dualbooting Ubuntu and Windows.
My Ubuntu partition is limited to 30GB, and the Windows partition gets all the remaining disk space. Does /host suffer size limitations while being accessed through Ubuntu, or it's size is the same as the Windows partition?

View 14 Replies View RelatedI have a network camera, with a linux OS. We need it to be really precise in its timing for the specific application we want it for. But it's not!
After killing some of the garbage processes on it (and having some achievements, but not enough), it seems that there's some kind of bandwidth limiting applied on the outgoing traffic.
My question: What are all the things that should be done on a machine, running linux, to remove all the bandwidth limitations?
Notes:
1- With my very basic knowledge about traffic shaping in linux, I have made these observations:
# tc qdisc ls dev eth0
qdisc pfifo_fast 0: root bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
# tc qdisc del dev eth0 root
RTNETLINK answers: No such file or directory
2- I am trying to download the images from an HTTP link, and I already have about 14Mbps. I want it to reach at least 50Mbps. I can download with speeds higher than this when downloading from another PC on a windows network. So I assume this is not a problem with the cables. Also the eth0 on the camera is said to be a 100Mbps device.
What are all the limitations in Redhat enterprise linux 5.3?
How much would it cost right now?
Does anyone know if there is a size limitation for shared-memory segments in RHEL AS 4?

View 7 Replies View RelatedComing to the point, as per object, I'm playing ( read also as "messing up" ) with mldonkey since last weeks and I have managed to get it working correctly on my home network ( behind router and firewall ). Next step in my development plan was to enable remote access to mldonkey web interface from any external network, like for example a friend pc. I'm aware of the "IP Access Restriction" in the mldonkey configuration file (downloads.ini) but there I can only specify an ip ( or ip-range) to allow access.
So the question is: how can I manage to disable* ip restrictions upon access, so that with a DNS-aliasing service I can access mldonkey web page virtually from anywhere?

I need to make some solution for my home network, I have a linux server which is: Linux Centos 5.5. So, what I need to do is to make a virtual interface for my clients which set its bandwidth up to 1Mb/s shared to them, but my real bandwidth is 2Mb/s. Also, after that, I have two questions:
1. How to set this rate limitation to that interface?
2. How to edit this interface to let it work and route the client data to my ADSL router?
I'm already generate the virtual interface using webmin managment tool, so I need to set its rate and route data.
I'm having this strange behaviour. If i ssh -X remotehost, and then i issue firefox, the localhost firefox is activated.
View 3 Replies View Relatedi am wanting to use Firefox to connect to my smb shares. However, i keep getting this error message: Firefox doesn't know how to open this address, because the protocol (smb) isn't associated with any program. My client configuration is as follows: Mozilla/5.0 (X11; U; Linux x86_64; en-GB; rv:1.9.1.8pre) Gecko/20100106 Ubuntu/9.10 (karmic) Shiretoko/3.5.8preI tried the instructions below to try and fix the problem with no success: Quote: From [URL]
Linux with Firefox In order to connect to a network share directly from you browser under Linux, you must configure Firefox to handle URL's starting with "smb://". This is done by typing "about:config" in the address line and hitting return. After that you must right-click the list of settings and choose "New -> Boolean" as shown below.
As name you must type: "network.protocol-handler.external.smb" with a value of "true". After that you must do the same thing over again, but this time choose "New -> String", type the name: "network.protocol-handler.app.smb" with a value of the path to the application you wish to use for browsing network shares. If you use KDE, this will typically be "/usr/bin/konqueror".

How do i roll back firefox5beta to firefox4 and keep updating to the latest stable releases w/out upgrading to beta? The only extension that isn't working is FEBE which is incompatible w/ firefox5beta (profile, extension and preference backup). Have to use FEBE beta7 under Firefox4 so I don't think a compatible release for Firefox5beta is going to come out any time soon.

View 2 Replies View RelatedI recently upgraded (via Ubuntuzilla) to firefox 3.5.7 and now, every single time I close Firefox, the program seems to crash without quitting completely.
First, I receive an error saying that the program will not close and asks me if I want to Force Quite or Wait for it to close on its own. This has been happening ever since I upgraded to Karmic and if I just wait it usually quits fully after a couple seconds.
Now what happens is this: the window still closes, but if I try to reopen Firefox then I get this error stating that Firefox is already open and therefore cannot be opened again. The only way to get back into Firefox is to restart the entire computer. (Incidentally, this is the same problem that occurs whenever I try to Force Quit Firefox)
This now happens every single time I "close" Firefox.
Does anyone know the source of this error? Or a workaround?

How do I force Firefox to recognize a certain default firefox profile I have?
For whatever reason I can't get FF to show all of the add-ons I have. Yes, they are installed and they appear when as icons when I first boot up but after I close FF and start it again there are no icons (like Adblock).
Im using firefox version 3.6.12 and it functions fine. However when i use the latest version of this addon https://addons.mozilla.org/en-US/fir...11377/#reviews the screen goes grey and firefox crashes. Restarting firefox only results in more crashes. I had a older version of this addon-1.5 i believe that worked fine.
