Networking :: Bandwidth Monitoring - Log Based On Usage / Consumption?

May 10, 2009

Can you suggest bandwidth monitoring software for GUN/Linux that will log bandwidth based on usage/consumption.

Not options:
- slurm or any other "real time" bandwidth monitoring
- /sbin/ifconfig <interface> | grep "RX bytes" or the like

What do you use to monitor your monthly, daily, hourly bandwidth consumption (assuming that you do).

Fedora Networking :: Controlling A Running X Server Remotely?

Apr 11, 2009

*Solved* I have been reading the following guide on how to use the VNC programs and a GUI to connect to my main machine from my laptop via my LAN and router:

[URL]

This allows me to control the server remotely, and run applications on the server remotely, with the GUI output being shown on my laptop, which is really neat I had Eclipse + PDT running on my server and had to stop it and start a new instance remotely from the laptop via VNC viewer, as Eclipse said the workspace I wanted to use was already in use.

So starting the VNC server on the main machine does not allow me to access the programs that are already running on the main machine under the native X server. However I can now do PHP debugging remotely using Eclipse + PDT now, and all the PHP source code is on the server machine. That's OK, but I would like to do more than that. I want to be able to connect to the native X server on my main machine, and control all the applications running on the main machine remotely from my laptop, without having to shut them down and restart them again via a VNC viewer.

Is there some sort of remote control program I can use to allow me to connect to the running X server on my main machine from my laptop, and control those applications remotely please, so the desktop layout on the main machine's screen is mirrored on the laptop screen?

Ubuntu Networking :: Controlling Totem Over TCP/IP / Send Signals To Totem?

Feb 22, 2010

I have a desktop hooked up to a router and plugged into my TV. I like to run Totem and have videos running full screen on my TV. I would like to control that Totem using my laptop (connected to the same router over wifi). How would I go about doing that? I connected to my desktop using SSH and tried to send signals to Totem, but nothing worked. I tried using VNC, and that was ineffective as well.

Ubuntu Multimedia :: A Bug In The Display Off Mode Energy Conservation

Nov 12, 2010

After installing Ubuntu 10.10 on a laptop Acer Aspire 5942G graphics card ATI Mobility Radeon HD 5650, some time after the boot falls color monitor. Color depth is only 65000 colors or more. In all settings, all is well (and the color depth is there spelled 24bit). Color depth is reduced at some time after a reboot. After further experiments with the screensaver was set: color spoils the energy saving mode and turn off the display!After disabling the option "disable display through .." color is now always saved in the norm!

General :: Turn Off Monitor (Energy Saving) While In Text Console Mode

Nov 3, 2010

How to configure Linux text console to automatically turn of the monitor after some time? And by "text console" I mean that thing that you get on ctrl+alt+F[1-6], which is what you get whenever X11 is not running. And, no, I'm not using any framebuffer console (it's a plain, good and old 80x25 text-mode). Many years ago, I was using Slackware Linux, and it used to boot up in text-mode. Then you would manually run startx after the login. Anyway, the main login "screen" was the plain text-mode console, and I remember that the monitor used to turn off (energy saving mode, indicated by a blinking LED) after some time. Now I'm using Gentoo, and I have a similar setup.

The machine boots up in text-mode, and only rarely I need to run startx. I say this because this is mostly my personal Linux server, and there is no need to keep X11 running all the time. (which means: I don't want to use GDM/KDM or any other graphical login screen). But now, in this Gentoo text-mode console, the screen goes black after a while, but the monitor does not enter any energy-saving mode (the LED is always lit). Yes, I've waited long enough to verify this. Thus, my question is: how can I configure my current system to behave like the old one? In other words, how to make the text console trigger energy-saving mode of the monitor?

Debian Configuration :: Increased Power Consumption On Kernels >= 2.6.38?

According to Phoronix [URL]... aspm&num=1 (which seems to only test Ubuntu kernels) the problems should affect all users of the affected kernels, including Debian's, but that article provides a fix. I don't remember anyone here mentioning lower battery life and increased heat on their mobile platforms, though.

Fedora Hardware :: Power Consumption In Runtime Level 3?

Mar 21, 2010

I'm very curious about something. I like to use my command line as much as possible. So, most of my work and usage of my computer revolves around the command line. In such a case I could work without having to use any graphical interfaces. My only current limitation is WLAN connection isn't working for me, but that belongs in another thread and something for me to do for now.

My question is, Is it worth it in terms of battery life to work in level 3 when running a laptop on a batter? What sort of extension to the life would one expect?

OpenSUSE Hardware :: Fan Noise And Battery Consumption On HP Envy 15 - 11.3

Sep 5, 2010

The fan noise caused by my HP envy 15 when I'm using OpenSuse 11.3. When the computer is under W7 there is almost no fan noise. In OpenSuse, however, every three or two minutes the fan goes very loud. It sounds as if the machine were doing hard processing work when it is just surfing and doing office stuff.

Another issue is the battery consumption, I already tried the power option but the under OpenSuse the machine eats the battery in almost half of the time than under W7. it stands for just one hour under OpenSuse, when it uses two in W7. These machine comes with a core i7 and an ATI graphic card.

OpenSUSE Install :: Power Consumption With Blank Screen?

Jan 7, 2011

I have installed a new PC system

- OpenSuSE 11.3, 64bit
- AMD Phenomen II X4
- ASUS M4A88TD-V Evo/USB3
- 3 hard disks
- etc.

After start-up with runlevel 3, no applications running, network is up, the overall power consumption of the PC (without monitor) is ca. 70 Watt. After some minutes the monitor goes to power saving (terminal mode, runlevel 3 !), but the power consumption rises to 120 Watt! After pressing a key on the keyboard (e.g. Num) the monitor leaves the power save mode, shows the login screen, and the power consumption falls to 70 Watt. In parallel I have investigated the system via ssh and running top, but I have not observed any abnormal operation. I looked into /proc/acpi/* but I did not find something unusual.

General :: Unable To Model The Power Consumption Of Various Components

Aug 3, 2011

I am working on a traffic surveillance project which performs various image processing tasks with a number of visual sensors and a computing platform. My basic task in the project is the power optimization/management. I am using a ZOTAC-IONITX computing platform (Intel ATOM CPU + NVIDIA ION GPU). The problems that I am currently facing are:

I am unable to model the power consumption of various components e.g., processor, GPU, hard drive, memory etc, since there seems to be no way to measure the power consumption of individual system components. Since I don't have a power consumption model, I cannot come up with a power optimization algorithm. I am currently working on Linux. Is there any way to measure/model the power consumption of individual system component?

I have already checked powertop. It doesn't tells the power (watts) consumed by a component (e.g., microprocessor). It just gives information about the power state the processor is in (However there is no way to change the power state by the user) and the processors that cause processor to wakeup.

Ubuntu :: Going Green - PowerTop And Cutting On Power Consumption?

Feb 27, 2010

Judging by the number of responses (close to zero) to other threads about powertop on this forum, I have little hope in getting any answers. However, I do not know where else could I ask. PowerTop tell me that even after applying almost all the tips and tricks from lesswatts.org, my laptop still consumes over 72 Watts while idling.

Code:
< Detailed C-state information is not P-states (frequencies)
1.60 Ghz 0.0%
800 Mhz 100.0%
Wakeups-from-idle per second : 451.1 interval: 10.0s
Power usage (5 minute ACPI estimate) : 72.5 W (0.3 hours left)
Top causes for wakeups:

[Code]...

Suggestion: Enable USB autosuspend by pressing the U key or adding usbcore.autosuspend=1 to the kernel command line in the grub config This is when I am not touching the laptop. When I am surfing the web or listen to music, it goes up to 2000+ wakeups! How do I cut it further? I am getting like 20-30 minutes max on battery and this is unacceptable cause in Windows I get at least 3 times that.

Ubuntu :: Get Files/bookmarks/ - Higher Power Consumption

Jul 5, 2011

What my situation was before the problems:

-I dualboot win(xp) and xubuntu(11.04)
-No problems whatsoever except for the fact that power consumption was higher on xubuntu.

Then i read something that said that the kernel i was using was effectively having power issues and that it could be fixed so in went into the terminal and nano'd the grub config file and update-grub'd with the addition i had read all over the internet. When i rebooted it seemingly had worked but once i opened a ..... video it didn't react to anything (i'm 99% sure kernel panic since there was no hdd movement). So i forced it to shutdown and when i got back in again i nano'd the file again but for some reason i didn't only remove the power stuff but I also removed the quiet splash. Once i had rebooted it would suddenly ask for username and password twice.

once the older looking menu an then the newer looking one with the fancy bg). The first time i got in okay but afterwards i could only get in as root. I thought i had simply forgotten my password but i ran passwd myusername as root and it didn't work(only when i typed something random it gave the wrong password message). As root i also can't edit the users and groups(when i open it it stays grayed out). how do i fix this. If i will lose my account anyways then how do i get my files/bookmarks/... of of it.
