Hardware :: Using One Power Supply For Multiple Motherboards
Apr 19, 2011
Is it technically possible to use just one power supply for more than one motherboard?The reason for asking is that I have a number of old (a few years) boards that I would like to use to make up a blender render farm yet only have one spare PSU. Having looked at the pin spec URL...pin 16 (power on) should only be connected to one board (or have a manual switch to ground for on)Pin 9 (standby +5v) probably should only connect to the one board or none and the other (or all) boards would need pin 9 to be tied to a +5v pin.All the boards would network boot and have nothing connected to them, no disks, floppies, monitors, etc; as all data would reside on a network server.

I just recently installed Ubuntu and my power supply cooling fan won't power down normally when I would run windows tho it would power down after the system was finished starting up. How can I remedy this?

Does anyone had any experience with fanless, low-powered power supply units (PSUs)like PicoPSU? Please share your experience.
I am also interested to hear about experience concerning the fanless cooling solutions and/or power-scaling for low-end CPUs like Intel's Atom, AMD's Neo or Via's Nano.

is this a good combination to use with 8 GB of RAM and 2.6 GHz AMD Hex core? The power supply will be replacing a 450 watt power supply and the video card will be replacing an ATI 5750 1 GB (Which currently doesn't work without 10.9, so far) The problem with these is that it doesn't meet the AMP rating of 38A of the GTX 470.

Is there a way to do that since the computer and OS is aware that the power supply is disconnected.

I have a 500GB WesternDigital Elements external harddrive and recently I plugged it into my computer and noticed the green light on the power adapter didn't light up anymore. I'm assuming that the power adapter failed - is this a fairly safe assumption? I know it COULD be something else, but does this at least make sense to move forward?Coincidentally, I've been researching new externals to order a 1.5TB because the 500GB is full.
I'm contemplating two options:
1.) Replace the power supply for ~$40
2.) Take apart the external and mount it internally
If it is in fact the power supply it might be the best option to just replace the thing and have 2 externals for backing up data on. But if it turns out to not be the power supply I'm out $40.I'm not sure how taking apart the external and install the hard drive in a desktop computer would be. Is the harddrive a standard drive? Does it have all the same power cords a normal computer would? If so, I could just install it into my brother's desktop and retreive the data that way (and he'll have an extra 500GB hdd).

I have installed on my computer Solaris10 (64bit version), PCBSD8 (64bit) on 2 primary partitions and 7 Linux distributions (Redhat,Debian,OpenSuse,Fedora,LinuxMint,Slackware,Ubuntu) on the extended partition. I know this might be a stupid question, but here it goes: I have a problem with my actual power supply unit (the fan doesn't work as it should) and I will change it soon. Is there a problem with any of the Linux distributions if I change my power supply unit? I mean, will the Linux operating systems work properly with a new power supply unit or do I have to reinstall all Linux distributions?

My router/adsl modem is not connected to a power supply so when power goes and comes the network will do a re-boot. Now the problem is my OpenSUSE network won't come back on! I set the static ip as Autoeth0 to eth0 however when network updates I losse eth0. Why is this happening? Why doesn't the PC simply re-connect? Can I do it via command line?

So now that it's working the Server can't be seen from the internet. I see that the router changed all the ip address so I changed the fort port forwarding on the router and still not working. And the external ip address has not changed.

This thread [URL].. was the only one I could find on this forum that addressed the problem I am having. It also involved a Gigabyte motherboard. I recently purchased a Gigabyte GA-MA770T-UD3 motherboard which is a version 1.3 . I have a v. 1.0 of the same motherboard which I have used regularly for a year.
The problem I have is that newer versions of Ubuntu (10.04 and 10.10) don't boot reliably with the new motherboard. It will boot up to where it says "Begin: Running /scripts/init-bottom. Done." and then will stop. If I hit any key on the keyboard the boot finishes and everything is OK. Sometimes it will hang like this but often it will boot successfully without assistance. I need it to boot by itself reliably every time.
Older versions of Ubuntu (8.04 and 9.04) boot just fine with the new board. If I put the drive with the 10.04 installation in my older Gigabyte v.1.0 computer, it boots reliably every time. Interesting to note that Windows XP sp1 installs fine on the older v. 1.0 computer but I need XP sp2 in order to do a successful installation on the v 1.3. I have stress-tested the new setup for 6 hours without incident and memtested the RAM for 4 hours without error. I have even swapped RAM between the two with no resolution.
I can't find any thing in syslog to explain this. It stops just before the splash screen comes up. I removed splash with no positive result.

I would like to connect my pc to the TV but the vga cable is not compatible with my analog Tv.The pc that i'm using is equipped with everything, except it hasn't got an agp port for my TV-OUT video card.I have a second motherboard with cpu(+power source) on it, but it's too slow so i don't want to use it.So! My idea is to connect the pc to the second motherboard, and use the second motherboard just for the agp and the TV-out video card.(i really don't have no money for signal converters and new video cards at all)

I have two servers (A and B) which are identical. My idea was to have a software RAID 1 with both of them running and if server A craps out I wanted to swap the hard drives from server B into server A. When I tried to test this idea the network driver doesn't seem to want to cooperate. ifconfig gives nothing and I can't figure out why. From googling I've read that a network card has a unique ID on it (I'm assuming their talking about the MAC address) and is used in some config files which is why swapping hard drives gives two different MAC addresses and confuses the system. If that is so would anyone know exactly what config files the mac address is stored/used in? That way I can make a backup of those files and swap those out if I ever need to swap out the hard drives.

The upstream provider is supplying samba3x (currently samba 3.3.8) packages in their supplementary repository. I know that most of what is in the supplementary repository is burdened with restrictive or non-free licenses, however, Samba is not.
The samba3x packages are critical for Windows Server 2008 trust relationships as well as Windows 7 client support for a CentOS server acting as a Windows domain controller. I know that I can either roll my own packages or compile from source, but an officially supported version would be a much better option on a production server.Is there any way CentOS can "officially" supply these packages and their associated dependencies?

I am trying to write an irc bot to run interactive fiction games in a channel. I am connecting to the channel using nc. I'm having a hell of a time trying to supply input stdin for nc after the connection is established. Here's what's going on. I've got lines of plain text in a file with the irc commands required to identify the bot's ID and join the channel. I can connect easily using any of the following commands
cat inputfile | nc irc.servername.org 6667 -i 1
nc irc.servername.org 6667 -i 1 < inputfile
Named_Pipe | nc irc.servername.org 6667 -i 1
cat inputfile > Named_Pipe
With the first two commands nc connects, reads the file with some time between each line allowing the irc server to respond, bringing me into the channel. It then begins to receive stdin from the command line allowing me to do things like "privmsg #channelname :Hello World!!!" sending messages to the room. This is not the desired behavior. I require nc to take additional stdin from the inputfile if I cat additional text to the end of it.
The last set of commands using the named pipe seem like it does the same, but it doesn't actually send anything to the room, which indicates to me that perhaps nc is continuing to take stdin from the named pipe (this is the desired behavior) rather than dropping to the console for stdin. If I try to cat more plain text data to the end of the named pipe, however, either with something like "echo 'privmsg #channelname :Hello World!!!' > Named_Pipe" (or >> instead of >) or with a filename in place of the "echo" command the whole command simply seems to hang until I press ctrl-C.
I don't understand what I'm doing wrong. With anonymous and named pipes, and with redirection, the problem seems to be the same. nc seems to take it's stdin from the file until it hits the end of file, at which point I can no longer introduce new lines of plain text as stdin for the running nc process.

I followed this tutorial to encrypt my entire installation: SDB:Encrypted root file system - openSUSE
It worked splendidly and whoever wrote it should get a lifetime supply of beer. After I got the install encrypted I made a RAID 1 array of 2 1GB disks and encrypted that as well. They are used for a data repository.

I use Squeeze with Xfce. My problem is that recently (after the xfce updates) the xfce power manager doesnt react to the power button - it is set to suspend. I dont have gnome-power manager or anything like it running.
If i reboot the computer, the power button will work but if i suspend and resume, it doesnt work again.
The computer is built on an Asus M3N78-VM mobo (2GB RAM/Athlon3200+ single core).
acpi_listen detects the button press.
Any thoughts?

I am using Ubuntu 10.04 64-bit and I purchased a new ALFA AWUS036H wireless card. I would like to know if this "1Watt" wireless card is configured for full power. iwlist wlan0 txpower results:
wlan0 unknown transmit-power information. Current Tx-Power=27 dBm (501 mW). It appears to me that I should be able to increase the power. "iwpriv wlan0 highpower 1" does not work. Do I need to patch the new default driver that comes with Ubuntu 10.04 64-bit with the aircrack one following these directions:[URL]...? Monitor mode and a injection tests seem to work fine with the driver I have installed.

I'm looking for any power monitoring devices for Linux to allow monitoring power quality, voltage changes, and outages. This would be for North American three phase power system. I want to have this data fed live to my own program. It should be something much better than just jury-rigging a circuit to fee the power waveform into 2 or 3 audio cards.

I had unplugged my PC last night as sometimes there's storms at night this morning I plugged in PC and the power light is blinking and the PC wont come on at all tried different power cord, same result
PC is a AMD athlon64 3300+ 2.4ghz SiS graphics
probably the power-supply or what?
If it is the power supply, how do I find new one as I've never had to replace anything on it or any other PC?
Also, I really need access to the hard drive but it's a weird hard drive and was wondering if I could put that hard drive in my K7 PC, which already has 2 drives in it can a pc have 3 drives? do I have to add/have another ribbon cable for 3rd drive?

On the last release, I had this app installed where I could pick my power profile. I could use power conservatively, and performance would suffer a bit, but longer batt life,or I could have it automatically detect, or I could have the apps use all the power they want and then some. I'm looking to reinstall that app. What was the name of it?I can't remember, and so far, can't find.
