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 worksâ€”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 sinksâ€”one on the built-in AMD 780G graphics chipset and the other on the AMD SB700 southbridgeâ€”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 resultsâ€”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've been using Ubuntu 10.x for several months without any major problems. Everything was fine until this week.
In the past few days there's been a strange new problem. When I turn my computer on, it works fine for 10 minutes, and then the hard drive suddenly starts spinning and won't stop. While this happens the computer is virtually unusable. Mouse moves slow and jerky; apps don't respond; and eventually the windows close by themselves, the whole screen goes blank, and the system reboots. The whole process takes a long time, sometimes 30 minutes.
The only change I made just before this problem started was upgrading Firefox Beta 4 version 10 to the latest version 11. So, I deleted it, and went back to the latest stable version 3.6.x. That seemed to fix the problem for a day or so. But then it started happening again. I deleted all signs of Firefox; it still happens. So it's not a browser issue.
I am stumped. Today I started my computer and just let it sit there without opening any programs at all except the system monitor. It ran fine for the usual 10-15 minutes, nothing changed out of the ordinary in terms of computer resources used in the system monitor, and then suddenly the drive started spinning wildly again .....
Right now my computer's been on for 10 minutes and I am typing this message .... but who knows what will happen right now.
I configured ssh on one of my servers to require public/private key authentication and deny access to login requests not using a public/private key. Now I need to unconfigure that,but I can't remember how I did it. I've looked through ssh_config and sshd_config, and nothing rings a bell. Googling only tells me how to enable public/private key authentication, not how to require it or stop requiring it.
I am looking for a way to configure rTorrent to stop downloading all torrents after they have downloaded x amount. For example, specify 15mb and as soon as the torrent reaches that size have it finish downloading the pieces it has requested and then start seeding partially completed. The reason for this is I'm trying to come up with a way to build ratio on a site where torrents are added very fast and at a very high frequency.
I download and add the torrents to rTorrent automatically via RSS, but I only want to download a small amount and seed that small piece while there are still a lot of people in the swarm (swarm drops off very quickly) and come out with a positive ratio from that small piece, beating the ratio clock so to speak. I thought it would be an interesting all be it somewhat impractical exercise in shell scripting, if rTorrent can be hooked into like that, documentation is sparse in some areas.
I am trying to configure redhat cluster first time but no idea how to do it. I am using rhel 5.2. I have copied cluster rpms from redhat media and tried to install them but facing alot of dependencies problem. Can some one please guide how can i do redhat clustering from start. I am doing this for configuring single node clustering for zimbra suite but it is the requirement to configure redhat cluster first. One more thing i am using two virtual machines installed by using virtual box.
I am running OpenSUSE 11.2 (but I do not suspect that this is distribution-specific).Linux bach 126.96.36.199-0.1-desktop #1 SMP PREEMPT 2009-12-15 23:55:40 +0100 i686 i686 i386 GNU/Linux.I am running in runlevel 3 while trying to sort this out.When smartd runs, it spins up my Western Digital drives from standby, but not my Samsung drive.Anyone know why blkid, edd_id and devkit-disks-pa are reading my standby drives? And are these reads sufficient to make drives spin up? I'm not sure what to look at next.
I think I selected the wrong time during the installation and now at the top right corner, my time keeps changing back to one hour ahead. Not sure why.I've went into the Preferences of the Time/Date > Time Settings > and set an hour back manually. I check back in 30-45 minutes, it's back another hour ahead. I'm on a Dell Inspiron 1545.
i recently switched to ubuntu 9.10 from win vista, i am having a problem... in ubuntu when ever i do any changes it asks me for my password, i know that its for my own PC's securiety but now i am really annoyed with this.
I recently bought a Shuttle XS-35 Mini-Barebone-PC and filled it with a 2GB Corsair RAM and a 1 TB WD Scorpion Blue Drive.After assembling all the parts I simply wanted to install Ubuntu but it simply doesn't work. However then I had the idea it would be good to kinda get the drive to a completely clean state and used the tools to safely wipe the whole HDD (by writing zeros everywhere as the tool tells me). The tool ran good for around 30 minutes but suddenly the write speed showing in the console window would go down to 0B/s (meaning basically nothing at all I suppose). I tried it 2 more times and it always came to a halt at the 10-20GB mark.
So this lead me to belief that that is also the problem while installing, that my drive doesn't want to wark anymore but rather just sleep a bit.What could be the problem? Is it a hardware error? Is there some linux system setting that could whip my HDD whenever it gets lazy? Did I do something else wrong?
Just installed F15 using preupgrade (from F14) and now, every time I reboot, time jumps backwards 4 hours. If I reboot twice in a row without correcting the time, time will be off by 8 hours. Time zone is set correctly (Eastern Time). "Synchronize date and time over the network" is unchecked.
Since the difference between GMT and Eastern time is 4 hours, there appears to be some confusion over that but I can't find anything in the "Date & Time" app relative to that to try to play with to see if I can correct this. II do remember a similar issue many releases ago but I can't remember how it was dealt with.
I'm trying to develop a system that records different desktops at the same time. I have developed a audio-videochat system and I want to be able to record what happens in every room, so my starting idea was:
1) Open a graphic terminal for each room. I have succeeded using vncserver :NumberDisplay. 2) In each terminal, run firefox at each URL. I succeeded too because firefox lets me specify in wich NumberDisplay I want it to be open 3) In each terminal, run recordmydesktop to record. It allows too to specify the NumberDisplay.
My problem now is that it seems that the sound card is "shared", so the sounds recorded in the display 1 includes the sound generated in all others firefox windows. I havnt found an analogy for the sound as the display is for the graphics.
I have thought some ideas but I havnt been able to materialize anyone. Im tried to create virtual sound cards and specify one for each vncserver, I tried to redirect the sound of each firefox window to one "channel" (read firefox delegates the sound so that might not be an option), I read many things about pulseaudio, jack and several stuff that I just havnt been able to work.
Every time I boot up I have to go through a disk check and then restart, how do I stop it from happening? When the disk checks happening I press escape and it usually says its deleted inode something because it has zero Dtime or some thing similar and also a paragraph of repeated lines saying something like all system files need alsa base.cnfg it will be ignored in a future release then the disk check completes and it restarts and is fine then, also sometimes it says dev/sda5 (my ubuntu partition) was not cleanly unmounted check forces. Is their a way to stop this happening as it ends up taking ages just to login.
i'm running 11.2 kde 4.3. i'm having issues with both smplayer and vlc. first, when i play an audio cd through smplayer, it pauses every 14-15 second. by pause i mean that the sound and time counter stops, and i actually hear the disc drive make a sound, the *typical disc-read sound. i tried a few discs, in case it was a specific cd; same thing for all. i also looked through the preferences to see if there was a setting that addressed it; nothing i see seems to address the issue.
playing the same cds in kscd works fine. but kscd really sucks....excuse me, it really really sucks. with vlc, whenever i start vlc, it will appear in my taskbar, but there is no other sign of its existence besides this. no system tray icon, no gui or any other sign of its presence besides the taskbar.
I have Ubuntu 10.04.1 32bit installed on my flash drive so wherever I go I can have my own mini personal computer, but one problem I'm having is every computer it is run on the next time it's rebooted to the OS on the hard drive it has UTC time instead of the actual time for the timezone you're in that Windows uses. So is their a way I can make Ubuntu not automatically change the clock to what it wants?
I'm using debian 5 x64 with xfce.Is there a way to configure (start/stop/restart) services (especially Apache2, mySQL and PHP) using a graphical or cli tool? I tried to use sysv-rc, sysv-rc-conf, rcconf and rc-conf in the terminal but Bash didn't find them (Although Synaptic show that sysv-rc is installed).
I have a machine running Karmic sat in the corner of my office. I scp stuff from my mac to it quite a lot over my local wireless network.At the moment, it holds a .sparsebundle backup of my mac created by SuperDuper! (mac backup application) that I periodically transfer over. I'd like to make this system a little more sophisticated and use Apple's Time Machine to automatically backup to my Ubuntu box if possible.
Anyone have any experience of this? I'm kinda hoping for something a bit more straight forward than this: http:[url]....
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?
