My system doesn't reacts at writing values below 255 to /sys/class/hwmon/hwmon0/device/pwm(2,3) which correspond to 3-wire case fans connected via M/B (ga-890gpa-ud3h) headers. The idea was taken from [url]
ls /sys/class/hwmon/hwmon0/device/
It indeed shows the actual speed:
But refuses to write to fanX_input: permission denied (even for root).
More specs: kernel 2.6.38.4, sensors output is:
I do not run any daemons for fan control, but suppose the speed may be set by CPU in-kernel governor. How to stop a fan under this conditions without doing hardware tricks?
Upd: part of pwmconfig's output:
Devices:
Found the following PWM controls:
hwmon0/device/pwm2 is currently setup for automatic speed control. In general, automatic mode is preferred over manual mode, as it is more efficient and it reacts faster. Are you sure that you want to setup this output for manual control? (n) y hwmon0/device/pwm3 hwmon0/device/pwm3 is currently setup for automatic speed control.
In general, automatic mode is preferred over manual mode, as it is more efficient and it reacts faster. Are you sure that you want to setup this output for manual control? (n) y

I have a USB modem and a large C++ application that needs to detect whether that device is present or not. I was hoping to get advice for what the best method to do so would be. The only solution I've thought of is to parse the output of lsusb and look for the vendor and product ID of my device, but that seems a little hack-ish and inefficient. Is there a command or program that I can provide it a vendor/product ID for a USB device and it can tell me whether or not such a device is present in the system? Or another, better way to detect the device than parsing the lsusb output that I've been thinking
I am writing an application that has a web service client on a Windows PC that needs to call a web service on a Linux server. In order to create the client, I need to be able to programmatically read the WSDL on the server and use it to create the client. I'm using the web tools in MyEclipse to build the client.
The Linux server is running Red Hat, I believe, with ssh enabled. I can connect from Linux to Windows with no problem, but I can't reach the Linux box from Windows. I get one of three errors when I try: no path to host, connection reset, or unknown error number, depending on the port I use. I've googled for an answer, but haven't found anything yet.Is there some way to add the Windows IP to a permission file on the Linux machine so it will be recognized when it queries for the WSDL?
Given a matrix with 0,1 entries, how can I create a graphic in linux such that we have a black square or pixel if the entry is one and white otherwise?
For example, if the matrix is:
0001000 0011100 0111110 0000000
then I want a graphic that looks like:
[code]....
I will be working with many large matrices, e.g. 1000x1000, or 5000x1000 so I need to do this automatically.
I am writing an Air application and I would like to have the app use the font indicated in Appearance Preferences.
A similar problem to this one :
[URL]
I do not have Gtk::Settings and I have looked in ~/.gconf/desktop/gnome/ but I do not have an interface folder and none of the others I opened have any font details.
I have tried simply not setting a font within my application but it is using a font not specified in the Appearance Preferences at all. It looks like Times.
Ideally I would like to be able to get this information from Ubuntu using a native process :
[URL]
get the font name of the Application font or would I have to write a script and call that from inside Air?
I have a default installation of Ubuntu 10.4 with Unity running on top of Gnome. (I think this is correct. I certainly can get Nautilus running quite easily and as I mentioned earlier I have ~/.gconf/desktop/gnome/ folders).
The brief is to get the application working on the default installation so I cannot install anything but the target machine I am using has got 'gconftool'.
I need to generate pdf documents programmatically using Ruby. i.e. I don't want a GUI interface but an API interface. The bulk of my document is text but there are images included as well. I've looked at this thread: [URL] and it's 2 main recommendations PDFEdit and ImageMagik. PDFEdit has scripting available but I can't get my head round how to call this using Ruby. ImageMagik has a number of Ruby wrappers and is the kind of thing I want but as far as I can tell it only deals with Images and my stuff is mainly text.
Is it possible to do the following in C/C++ in Linux:Without direct linking (my program should NOT depend on Qt or GTK), display a GTK or Qt based file dialog.The behaviour should be something like this when my program runs, when you want to open a file:The program scans whether you have Qt installed. If so, it somehow manages to link itself to Qt (e.g. dynamically loading the .so file) and display its file dialog and get the path from it. If Qt wasn't found, it tries the same with GTK. If that also wasn't found, it displays a less powerful replacement dialog instead (better than nothing).
Or is there any other simple way in Linux to get a standard file dialog somehow (similar to when compiling for Windows you can very easily get its standard file dialog, no matter what version of Windows, in your code, even if your program doesn't use any other Windows GUI at all).
I wonder if there's a way to capture the same information I can get from nethogs to a file. All I need it per process (rather than per interface) what is the sent/received traffic.
I know the tool system-config-display can tell me all about my display but it's not available on all systems and so I'm looking for alternative ways to get my monitor type. Ideally, I could just look in /proc but I don't see anything there and I would like to be able to do so from a script perhaps written in bash or perl. Is there some place to get this info, say in a config file somewhere?
I am developing a application in which i have to show the name of default browser and mail client. i want to run this application on RedHat, SuSE, Mandriva, and Ubuntu. I have checked similar threads but not found any useful information.
whats the difference between restarting/stopping apache using 'service httpd restart/stop' and apachectl restart/stop. I know that using 'service httpd restart' is actually a script in /etc/init.d/httpd but what about apachectl?
This is an examination senario. We have mulitple users logging into a RHEL-4 server using putty. These people are part of a same group. They are giving UNIX shell script exam.They are helping each other copy the code by using redirection to /dev/pts/x. Is there any way I can stop this redirection?
I used the cmd "vncserver" to start a vnc session, and it created a log file like this "/root/.vnc/linux-vzra:2.log". As time going on, the file "/root/.vnc/linux-vzra:2.log" became bigger and bigger, it is too huge indeed. How can I start a vnc session without a log file?
I have a cron job that executes a rake task in rails. I noticed in the log that it was running the task 4 times everytime it was executed. The problem is that there are 4 instances of cron running.
I ran code...
So my question is how do I stop the other instances. When I run the stop command now I get this:
Stopping crond: cannot stop crond: crond is not running. [FAILED]
Any ideas? Do the other instances have different names? Is there a way to kill all instances as once?
I start/stop lots of new instances as I'm learning to use Amazon EC2. Every temporary instance is added to the known_hosts file. Is this ever a problem for others who use EC2 a lot?
I'd like to tell ssh to skip this step anytime I connect to amazonaws.com. Is there a way to do that in the config? I'm using Linux & openssh.
I was messing around with my drive trying some different arrangements of partition to get another one inside. overall the result doesn't differ much from the original but while messing with it I done a lot of steps. I thought GParted will do the minimal number of operations but it didn't. it just traced all my operations one by one. this gave it a few days worth of work. As I don't want to loose data I can't hit cancel but I don't want to wait few days for it. Is there any way to tell it to stop after completing the current operation? It's from natty ubuntu live cd.
I have a PC which I built ~3 years ago which had been running smoothly and silently until recently. Now, the CPU fan likes to spin up to 1200-1500 RPM even when it's idle, which is rather annoying. I have not made any recent changes (software-wise or hardware-wise) to it.
I installed the lm-sensors and hddtemp packages (via apt-get) and configured them. Here's a typical output at steady-state, where the computer's been idle for a while and the fans have been spinning for the same while:
These all seem fairly normal to me, so I'm perplexed as to why the fan continues to run at such a high RPM. What does the ALARM that's reported for in6 mean? Is it important? I've been playing around with the fancontrol daemon, trying to see if I could get better results than with the default fan management. Using the pwmconfig utility, I generated the following /etc/fancontrol file:
# Configuration file generated by pwmconfig, changes will be lost INTERVAL=10 DEVPATH=hwmon0=devices/pci0000:00/0000:00:18.3 hwmon1=devices/platform/it87.552 DEVNAME=hwmon0=k8temp hwmon1=it8718 FCTEMPS= hwmon1/device/pwm1=hwmon0/device/temp1_input FCFANS= hwmon1/device/pwm1=hwmon1/device/fan1_input MINTEMP= hwmon1/device/pwm1=35 MAXTEMP= hwmon1/device/pwm1=60 MINSTART= hwmon1/device/pwm1=180 MINSTOP= hwmon1/device/pwm1=100
This only sort of works—as soon as I enable the fancontrol daemon, the fan shuts off at first (good), but the temperatures of the 7 different sensors slowly rise, even when everything is idle. Eventually, when the Core0 Temp sensors goes past 35°, the fan comes back on, and then it alternates from being on and off at around 500-700 RPM, as the temperature goes back and forth across the boundary. It's certainly much more pleasant than 1200-1500 RPM, but it's still far from desirable.
Here's an example of the sensors output in that situation: $ sensors k8temp-pci-00c3 Adapter: PCI adapter Core0 Temp: +36.0°C Core0 Temp: +38.0°C Core1 Temp: +34.0°C Core1 Temp: +30.0°C it8718-isa-0228 Adapter: ISA adapter ..... cpu0_vid: +1.100 V
I opened up the case, and the CPU heat sink felt warm but not excessively hot. I tried taking off the heat sink, cleaning off the thermal paste, putting on new thermal paste, and putting the heat sink back on, but that didn't seem to have much of an effect, if any. The two other heat sinks—one on the built-in AMD 780G graphics chipset and the other on the AMD SB700 southbridge—felt noticeably hotter than the CPU heat sink. So, my question is this: What should I do to get this computer back to the state where the fan is off when it's idle? Can I solve this with a smarter fancontrol configuration?
I cleaned out the heat sink and fan as best I could with compressed air (there wasn't a whole lot of dust, but I got rid of what I could), but still no dice. Rebooting into the BIOS configuration gives me the same results—the fan still runs at 1100-1200 RPM, and the system and CPU temperatures are reported as 40-44°C. Should I add another fan? The integrated GPU and the SB heatsinks felt significantly warmer to the tough than the CPU heatsink. The BIOS reports a system fan speed and NB fan speed of 0 rpm (since I don't have more than one fan).
I loaded RHEL6 (first time ever loading it) and it would boot to the cmd line. I changed /etc/inittab to boot to GUI, now it freezes. I want to change it back, but do not know how to stop the boot process so I can get to the cmd line to re-edit inittab. I'm working in VMware vCenter.
clafiry what this means? It is in my secure log file: xinetd[5544]: START: smtp pid=6574 from=xx.xx.xx.xx xinetd[5544]: START: ftp pid=6465 from=xx.xx.xx.xxThey are repeated in my secure log hundreds of times, one every second or so.Also how can I stop my ftp and smtp service?

I'm running puppy linux and my wireless works for about 10 minutes before crapping out. Then I tried going thru the internet wizard again and it won't detect my wireless connection. All my other machines are using this connection at the same time with no problem. The situation is temporarily resolved when i reboot.
After manually setting the display brightness on my laptop, the system re-sets the value. If the laptop is plugged in, the value is set to full brightness; if it is not plugged in, it is set to dimmer. How do I stop that behavior?
Note that I am not talking about what it does in response to the event of plugging in or unplugging my system. It changes on it's own - usually several minutes after I change the brightness value. I have observed this behavior on different systems, different distributions, and different desktop environments.

When I have Skype running (not in "Offline" mode) I often see it start eating about 0.5 kb/s of my traffic (so the network quota meter is dropping inevitably and internet stops soon). When I restart Skype or make it go offline-online, it starts forwarding it's things again soon.
How to have Skype available for chat, but not sapping my traffic (at least when "ppp4" is up)? I feel the majority of traffic spent by Skype is unrelated to my own activities (I mostly use text chat).
