Ubuntu :: Use A Processor For A Specific Program?

Aug 27, 2010

Can I set up my system to use a specific processor to do one task, and another processor for normal applications.

Say for example, I'm using a program that relies heavily on your processor, I have a dual core, so I can use one core for that, and another for normal applications.

Security :: Researchers Working Toward Processor-Specific Attacks?

Nov 10, 2010

With the disappearance of an OS monoculture, attackers would do well to find attacks that are neither OS or application specific. One way to do that, of course, is to target attacks at hardware, rather than software. Now research out of Frances Ecole Superiore d'Informatique, Electronique, Automatique (ESIEA) moves a step closer to that goal: identifying a method for isolating the processor used by anonymous systems for the purpose of subverting that hardware.

Programming :: Running External Program On Same Processor?

Mar 2, 2010

The situation is that I have an MPI-parallel fortran program. I run it and it's distributed on N processors, and each of these processes must call an external program.

This external program is also an MPI program, however I want to run it in serial, on the processor that is calling it, as if it were part of the fortran program. The fortran program waits until the external program has completed, and then continues.

The problem is that this external program seems to run on any processor, and not necessarily the (now idle) processor that called it.

how I can call the program and ensure it runs only on this processor?

Extra information that might be helpful:

If I simply run the external program from the command line (ie, type "/path/myprogram.ex <enter>"), it runs fine. If I run it within the fortran program by calling it via

CALL SYSTEM("/path/myprogram.ex")

it doesn't run at all (doesn't even start) and everything crashes. I don't know why this is.

If I call it using mpiexec:

CALL SYSTEM("mpiexec -n 1 /path/myprogram.ex")

then it does work, but I get the problem that it can go on any node.

General :: Run A Program For A Specific Amount Of Time Starting At A Specific Time?

May 18, 2010

I want to record an internet radio station starting at 2:00am tomorrow morning. The specific program on the radio station lasts until 6:00am. The command I need to run to record the station is: Code:mplayer http://wjcu.jcu.edu:8001/listen.pls -ao pcm:file=indie_heat_of_the_night.wav -vc dummy -vo nullI'd use cron, but 1. I'm not sure how to and 2. it seems unnecessarily complicated for something that I only want to run once. If cron is the only/easiest solution, I guess I'll just have to resort to that, but I'd rather not.

Ubuntu :: Launching A Program From Terminal To A Specific Viewport (Compiz)?

Mar 18, 2011

Anyone know how to launch a program from CLI (command line) to a specific viewport? I start programs all the time from the CLI and there are times when I'm in "typing demon" mode and don't want to touch the mouse. Being able to launch a program to a certain viewport (Compiz, w. effects) would be really helpful at times.

I'm familiar with wmctrl and i can use the -a and -c options to switch to and close windows fine. I only have 1 desktop (9 viewports, though), and wmctrl's support for viewport seems limited at best. Ideally, I'd like to launch a program to a specific viewport, but just being able to move an existing one to a specific viewport would work, too.

Please note: I'm talking about moving apps to viewports AD HOC or DYNAMICALLY, not in a fixed way like I believe devilspie and such (and Compiz' Place plugin). Depending on my task, I need to quickly launch several apps to different viewports, and this VARIES for me a lot. ubuntu 10.04 lts / gnome / compiz w. full effects

Fedora :: SELinux Turn Off For Specific Program?

Jul 19, 2010

One thing I have had to do to launch Maya every time is disable SELinux.

echo 0 >/selinux/enforce

I type that each time before I launch maya. If I don't it wont start.

Not sure why. Essentially it makes it so I need to be su to run maya.

If I was setting up the workstation to be used by others as well how would I disable SELinux just for starting Maya but nothing else? Or how to do I tell SELinux maya is ok for regular users to run?

Ubuntu Servers :: Program/Process Route To Specific Network Device?

Jul 30, 2010

Is there a way to bind specific programs to specific network devices (not IPs, since I have dynamic IPs)?

For example, I wish for irssi to route through eth0 and w3m to route through eth1. Keep in mind these devices have dynamic IPs, so I cannot attached them to an IP.

The solution cannot be accomplished through route since route pivots on IPs not devices.

Software :: Webpage Access At Specific Times Management Program For Ubuntu?

May 27, 2010

I'm having here at home one quite addicted Farmville & similar game player which I would like to somewhat control in at least late night/early morning hours, Was browsing a while around for a program which could be used as a webpage blocker for several hours (predefined time), but all I came up was either scripts which I don't understand (I myself can be counted as a newbie in Linux stuff) and don't want to risk blindly or just user account time manager (timekpr).

I found a great solution in my case for MacOS users called SelfControl, but as you can guess ... there's no Linux native client for that. So, my question is - is there any easy and understandable way to block specific webpages for a predefined time period (let's say, every morning from 03:00CET - 08:00CET)?

OS: Ubuntu 9.10 Computer knowledge of the farmer: Getting on Farmville and/or playing Gnome's Mahjongg is pretty much all.

Debian :: Force A Program To Use A Specific Version Of GTK When Compiling

Jul 15, 2010

I decided I was going to compile XChat from source today for "fun." What I ended up doing was spending a few hours getting it to compile, then find out everything didn't work the way I thought it did. I was under the impression that after I ran "sudo make install" I was "upgrading", when in reality I'm just installing a seperate version alongside the old one. Apparently I have to keep the old version so every program that was compiled with it will continue to work, so how do I:

1) Force a program to use a specific version of GTK when compiling.
2) Find where my version of GTK installed to.

I've asked some people and I've just been told to "learn LD_PRELOAD". I've googled and can't figure how I could even apply that to my current problem

General :: Execute A Program Based On A Keypress From A Specific USB Keyboard?

May 4, 2011

I've been given one of these ubiquitous usb-sleep buttons which is basically a supersimple usb-keyboard. It's a big button that sends a SLEEP keypress to the computer when you slam it. But that is pretty boring. I'd love to remap it to do something more fun but I can't figure out how to bind to only the sleep press from the button and not from my ordinary keyboard.

The button identifies as

Bus 001 Device 035: ID 1130:600d Tenx Technology, Inc.

I'd like to know if there's either

a way of mapping a key from a specific keyboard to an action OR a way of remapping the sleep key from a specific keyboard to a new key-code or something like that.

Hardware :: Multiple Barcode Scanners - Can't Seem To Redirect Output From One To A Specific Instance Of My Program

Sep 30, 2010

I have nine barcode scanners, each of whose input I want to send to a separate instantiation of a program I wrote. Each device shows up as /dev/hidraw_ (I'm using Ubuntu 10.4). The problem is that they all act as simple keyboard input, and I can't seem to redirect the output from one to a specific instance of my program. I've tried something like cat /dev/hidraw5 > ./myapp, and that doesn't work. I've tried actually opening the device in my program using open("/dev/hidraw5"), and it returns success, but subsequent reads don't do anything, and the scanner output is just printed to the console.

Ubuntu :: Run Program In Terminal With A Terminal Specific Profile From GUI

Dec 12, 2010

I'd like to run a program [URL] from the GUI menu (yes, I know I can run it from the command line). I've gotten this to work by using a menu entry (see attached screenshot).The command is:

Code:

gksu chkrootkit

with the option for Type: was selected as Application in Terminal However, when chkrootkit is finished, the terminal immediately snaps shut according to the profile selection: When Commands Exits: Close terminal What I'd like to do is create another profile that causes the terminal to be held open (see screenshot) when the command exits and be able to choose that profile from the GUI Menu entry. I believe the command when using the CLI is:

Code:

gnome-terminal --profile=<profile_name>

how do I incorporate this within the Command entry line of the launcher?

Ubuntu :: Allow A Specific User To Mount Or Remount A Specific Partition?

Jun 9, 2010

my system I want user1 and only user1 to be able to mount and unmount a specific partition, this partition contains backups and is usually mounted read only, needs to be temporarily mounted read/write by user1 while doing the backup.user1 is an unprivileged user. I've read that the user option will let any user mount the file-system (and only that user can then subsequently unmount it) and that the users option allows any user to mount or unmount the file-system.I also found this in mount's man pageQuote:The owner option is similar to the user option, with the restriction that the user must be the owner of the special file. This may be useful e.g. for /dev/fd if a login script makes the console user owner of this device. The group option is similar, with the restriction that the user must be member of the group of the special file.So it looks like I'd need a login script for that user to make the user owner of the device file (/dev/voiceserv/backup in this case)

Server :: Sendmail: Block Specific Sender To Specific Recipient?

Oct 1, 2009

I'm trying to configure our mail server to block email from a specific sender reaching a specific recipient. In other words, if one of our employees is getting harassed by a 'stalker', how would one go about blocking, at the MTA (Sendmail) level, a specific sender email address from reaching a particular users inbox? We do not want to capture the email - simply block it before it consumes server resources.The Sendmail server (MTA) is a front end to our Exchange server so no user accounts exist on the Linux server. We simply use it as a SPAM and Virus scanner then forward clean email to the Exchange server.
