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.
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?

View 1 Replies View RelatedIs 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.

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.

View 4 Replies View RelatedI 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).
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?

View 5 Replies View RelatedWhen I was using Ubunutu 10, I updated the ATI drivers from their web site and the installation failed. There is no uninstall for it that actually works. So, very annoyed, I switched to the VESA driver by editing xorg.conf as shown below.
I just upgraded from Ubuntu 10 to 11.04 and when it booted up it told me that I do not have hardware to run the Unity desktop. Even on a restart the login menu shows the selected desktop as "Ubuntu" (no classic or anything though my desktop looks just like it did in Ubuntu 10).
After upgrading to Ubuntu 11 it seems to have switched to a proprietary ATI graphics driver which actually seems to work very well. Except, no Unity desktop.
If I click System, Administration, Additional drivers it shows one driver and says that it is enabled and in use. The driver is "ATI/AMD proprietary FGLRX graphics driver" and in the description it says "3D-accelerated proprietary graphics driver for ATI cards".
Is there a way to explicitly turn on Unity or ask it why it doesnt want to run?

I do not really care which driver I use. I have been told there is a new driver included in Ubuntu 11 that supports my video card. Is that the driver I listed above or is thee another that I can activate somehow. What shall I do? I just want Unity to work.
Try disable this driver? Will it automatically pick up some default? Do I have to delete or do something to xorg.conf as well?
Is there a way to tell Ubuntu "forget whatever video card driver or configuration is in place and go back to the default for a new install"? I have tried "dpkg-reconfigure xserver-xorg" but all it does is ask for a password and then does nothing. Everyone says to run this buts its never done anything for me.

I'm wondering what the least err unit/ units are for a working Linux. For instance. Is a kernel + a window manager enough? Then let's say you install one app on top of that - now you have one app you can use, right? But is that right (kernel + window manager)? Do you even need a window manager for a functioning system? Do you need more than the window manager?I'm asking because I'm fixing to build something from the ground up but it isn't a regular Linux thing and I want to approach if from the direction of adding just what I need not taking away what I don't.

View 2 Replies View RelatedThe 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 want to ensure I have done all I can to configure a system's disks for serious database use. The three areas I know of (any others?) to be concerned about are: I/O size: The database engine and disk's native size should either match, or the database's native I/O size should be a multiple of the disk's native I/O size. DMA: Disks that are capable of Direct Memory Access (eg. IDE) should be configured for it.
Write-caching: When a disk says it has written data persistently, it must be so! No keeping it in cache and lying about it.
I have been looking for information on how to ensure these are so for CentOS and Ubuntu, but can't seem to find anything at all. I want to be able to check these things and change them if needed. The actual hardware involved is very modest. The point is to get the most out of what hardware we do have, even though it's "not very serious hardware" from a broader perspective.
My daughter from New Zealand gave me her Acer Aspire 4315 Laptop/Notebook Linux System in December 2009 so that I could use it in bed on days that I was unable to get out to use my main computer as I am a very ill man. I was able to log into the unit as she just said to me to use her name and password to. I have been able to use the unit on the internet at home and my other daughters home through a home wireless system. I clicked on the Upgrade Icon which it did, I think it went from a 7. something to 8.something All the way through the set up it asked me questions and I just clicked yes thinking that was what I had to do. My problem now is, that when I turn the unit on it asks me for a username and password. I put the details my daughter gave me but it tells me invalid user and password. All I do know is that a friend of my daughter installed the Ubuntu Program onto the Laptop/Notebook. Can anyone tell me how or what I have to do now to be able to use the unit again as I am getting very frustrated with the whole thing. I am not used to using Ubuntu and am totally lost with it as I have always been a Microsoft user.

View 1 Replies View Relatedhi, first i'd like to say that i'm totally new to linux, i was allways using windows.
as i was allways unable to install a good and stable ssh-server on windows, i thought it is time to change to linux. i was able to set up and configure a ssh-server on debian but found out, that fedora 15 looks more userfriendly in first place for me. but now i unfortunately experience problems..
the ssh server was already installed, i changed the service setting to that it starts automatically but after i succesfully connected to the LAN, i cannot access the shh via putty for instance. when i type "service sshd status" it says beside other things: active (running). but when i look at the /var/log/messages, it says those two lines:
sshd.service: main process exited, code=exited, status=255
Unit sshd.service entered failed state.
i searched on google without success, the only thing i found was that someone had the same problem with a bad sshd_config file, but i'm pretty sure that everything is alright with my config-file (i checked it several times).
beside this i cant login on the gui, after the firefox update (??) it always says: a problem has occured and the system can't recover bla bla... so i can only use fedora right now commandline-based.. but with this problem i will deal later on...
Does anyone know of a way to change the network charts unit of measure in Gkrellm from bytes/sec to bits/sec? I'm not finding any method to do so in the config options.
