• Ubuntu, No wireless networks found after correctly installed madwifi

  - by Peter

  Hi, I just installed madwifi on my MSI laptop with an Atheros AR5001 wifi card & Lucid. As far as I can see and according to System - Administration - Hardware drivers the install was successful and the card + driver is up and running. However, I don't see any wireless network (my windows PC can see about 5 wireless networks). I tried it with the network manager applet as well as with wicd. If I try to connect to "Hidden Wireless Network" via nm-applet, it will start to connect for a while but is unable too (although I supply it with the correct WEP settings & key) So, I'm unable to use my wireless network. What am i doing wrong?

• Cheapest server per gigabit throughput [closed]

  - by nethgirb

  I'm looking for a set of servers for performance testing a network, and secondarily testing some applications on the servers. Their most important task is simply to pump out data: from an application like memcached or just dumped from a large file in memory into a TCP flow (i.e., disk performance doesn't matter). This should happen over one or more 1 gigabit Ethernet ports, and the machines should run Linux (ideally), or perhaps Mac OS X or some other *nix. Other than that, there are few constraints (e.g., even something ARM-based could be fine). So here's the question: What's the cheapest server per gigabit? Price and power are both considerations.

• Windows Server 2003 Standby/Sleep Results in Cold Boot when Resuming

  - by Simon Chadwick

  I'm running Windows Server 2003 sp2 on a Dell Inspiron e1705. There has never been a problem going to standby/sleep mode (by closing the laptop lid, or from the Start menu), and then resuming later. Today I did a Windows Update to install the latest patches and fixes. I don't know if there is a correlation, but now when I resume from standby/sleep mode, the machine does a cold boot. The AC adapter is connected. The battery is 2 months old, and all its LEDs light up when pressing its test button. The Power Management shows it at "99% (charging)" all the time. There is nothing suspicious in any of the event logs. Any ideas?

• IBM Bladecentre H Bootup

  - by Spence

  I have a bladecentre with blades, network and a SAN in a single rack. What I'd like to do is control the startup of the bladecentre so that when the rack is powered on that the blades will delay their bootup until the SAN is powered on correctly. Is this even possible? We have an AMM in the chassis if that helps. Basically we are looking into the reboot that occurs after power is restored to a UPS. I sincerely apologise for the noobness of this question, but I am a software guy trying to help :)

• Which are the non-x text editors in Powershell?

  - by Andrei T. Ursan

  Are there some editors like emacs, vi/vim, specifically for power shell, if so which are the best? I will have to do some work on windows and I need some unix productivity - which means for me shell + text editor with syntax highlighting (for python, java, c, c++), so which are my options? Edit: I'm looking for an alternative at vim or other unix editors, and cygwin is not an option. I just want from the command line to say texteditor_name file1, modify it, save it etc, and all of these to happen inside the terminal, not in another interface etc.

• Drobo not mounting. Disk repair doesn't work either.

  - by kohei

  Hi, While transferring data to my 2nd gen Drobo power went out. Now my Drobo is not mounting to my OS X 10.6.3 I have tried Disk Repair and this error message appears: Verify and Repair volume “disk1s2” Checking Journaled HFS Plus volume. Invalid key length Invalid record count Catalog file entry not found for extent The volume could not be verified completely. Volume repair complete.Updating boot support partitions for the volume as required.Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files. I tried DiskWarrior too but it doesn't work either. It gives me that I need more memory to continue and software shuts down. Any one know solution to this one?

• Mobile Intel® GMA 4500MHD boost

  - by Andy Smith

  My machine has a Mobile Intel® GMA 4500MHD integrated graphics chipset. The machine is currently running 64 bit windows 7 premium with 3GB of ram (1x1gb and 1x2gb). I note that the Mobile Intel® GMA 4500MHD shares the physical memory to process the graphics. now, the total available graphics memory can be up to 1,340 MB with a 32-bit operating system and 3 GB system memory or 1,759 MB with a 64-bit operating system and 4 GB system memory. I am considering investing in a 4GB stick to replace the 1gb stick bringing the total up to 6gb, mainly for an increase in graphics processing ability. Can anyone let me know what sort of power (if any over the 4gb) I could expect by upgrading to 6GB?

• Proper management of PGPool II

  - by Cathy

  Currently I have a site, with one Postgres database server. It is just for a select number of users (less than ten) but it needs the maximum uptime possible. I would like some kind of automatic failover for the database. So I was thinking something like: one server running PGPool II, one running Postgres as master, one running Postgres as slave. But then, if wherever PGPool is running suddenly loses power (or dies, or whatever), there's a single point of failure and the whole thing goes down. Is there a solution, assuming that outsourcing this to someone else isn't possible?

• Thinkpad CPU temperature reaches 100°C after 10 minutes of heavy use

  - by Nicolas Raoul

  Less than two years ago, I bought a Lenovo Thinkpad R500. When using the CPU heavily, it sometimes decides to reboot. I am using Linux, and a widget shows me the CPU temperature. The PC usually reboots when the temperature of the first core gets over 100°C Since I switched from Ubuntu 2010.10 32bit to Ubuntu 2011.04 64bit, it crashes much more often. I survive using these techniques: When in the office, I use a laptopcooler. When outside, I underclock to 800 MHz, by doing so it does not get too warm. QUESTION: Is it normal that a Thinkpad crashes if the CPU is at 100% for more than 10 minutes? How can I use the full power of my computer, for instance when showing CPU-hungry business intelligence tools to clients? The computer does not really feel that hot. Maybe the sensor itself is reporting wrong temperatures? Can I tell the BIOS to ignore it?

• Slight network lag on Small Business Server 2008 R2

  - by Sir.Nathan Stassen

  I recently upgraded a network from a SBS 2003 server to a SBS 2008 R2 Server. Both I and users have noticed a slight delay in network applications and browsing network drives on the new server. It is minor, maybe a second or two at most. However I am wondering if anyone knows of anyway to optimize the networking to service requests sooner to the workstations. The network is running a 1 gig network with some 100 meg devices (mainly network printers). All workstations are XP SP3 Network software runs out of a shared folder mapped as a network drive, no sql databases. Server is a Dell Poweredge T610 with plenty of ram, cpu power, and storage.

• Experience with AMCC 3ware 9650se raid cards? Ours seems dead

  - by antiduh

  We have a 8-port 3ware 9650se raid card for our main disk array. We had to bring the server down for a pending power outage, and when we turned the machine back on, the raid card never started. This card has been in service for a couple years without problems, and was working up until the shutdown. Now, when we turn the machine on, the bios option rom that normally kicks in before the bootloader doesn't show up, none of the drives start, and when the OS tries to access the device, it just times out. The firmware on it has been upgraded in the past, so it's possible we've hit some sort of firmware bug. We're using it in a Silicon Mechanics R272 machine with gentoo for the OS. The OS eventually boots, but alas, without the card. We've ordered a new one, but I'm worried that if we replace the card it won't recognize the existing array. Has anybody performed a card swap before? Any help would be greatly appreciated.

• Problem with xvideoservice thief

  - by Nrew

  Xvideo service thief is an application that allows you to download and convert youtube videos into .avi format. The problem is when it tries to convert the .flv into a .avi. The audio in the video is not being played when you try to play the video. But the .flv works fine. I have also enabled Intel(R) speedstep feature in my processor(Pentium Dual core E5200) to decrease the power consumed by the processor with the help of Granola software. What might be the reason for the audio less video converter by xvideo service thief? Could it be the enabling of intel(R) speedstep? Because the software works fine when its not enabled. Is this possible?That the output some applications can be altered when enabling this processor feature?

• Most efficient way to use a laptop like a desktop? [closed]

  - by user74757

  When I'm at home (which is the vast majority of the time now in Summer), I rarely use my laptop away from my desk. When it is at the desk, I plug in a monitor through HDMI, a power cable, and a mouse and keyboard that always stay there. I was wondering if anyone had any recommendations as to a good dock or product that does a good job of transforming a laptop into a true "desktop replacement." Ideally, it would allow all the connections to remain in place, with minimal effort to take the laptop in and out of the fixture. Thanks for any suggestions!

• Odd Tools and Techniques for System Administrators

  - by Joseph Kern

  There's been a lot of questions centering on Software Tools for System Administrators. But I would like to know about any odd physical tools or techniques that you've used; Something that you never expected to be useful, but ended up saving the day. I'll go first: A Camera Phone. An application server had a major power issue that borked the RAID. Many of the disks were offline. Before I took the plunge and forced disks back online, I took a picture of the RAID BIOS screen with my camera phone. Having the exact layout of the RAID stored safely in my pocket, I was able to reset the RAID, and reboot the server. What odd tools/techniques have you used?

• TrueCrypt Failing to Decrypt External Hard Drive after changing Enclosures

  - by Anx Ara

  I have a 4TB external hard drive that was previously encrypted using TrueCrypt. The power source on the hard drive enclosure failed, so I had to switch the hard drive itself into a new enclosure. I can no longer decrypt the hard drive using TrueCrypt, as it says my password is wrong. I am certain that I entering the correct password. Additionally, in TrueCrypt, when I try to mount the volume under "Select Device", it shows the following: Harddisk 5: 3.6TB Device\Harddisk5\Partition 1 H: 465GB Whereas before I changed the enclosure it would show: Harddisk 5: 3.6TB Device\Harddisk5\Partition 1 H: 3.6TB I am on a Windows 8 PC and using TrueCrypt 7.1a. How can I get it to decrypt properly?

• Using 2-port LSI 2308-8e card to control 24 SAS HDDs

  - by GregC

  I would like to rely on a RAID-on-chip solution to control 24 SAS hard drives in a direct-attached environment. How would you approach this to get best bandwidth given that I'd like to spend less than $10,000 on the interconnect. I've read that LSI 2308 chip can easily handle 8-drive SSD RAID6 in hardware. I'd like to harness its power to control 24 SAS hard drives over an expander in an external enclosure. Currently I use an Infortrend S24S-G2240 external enclosure. It provides its own controller and expander. I'd like to use LSI 2308 controller for RAID6 somehow instead of the mystery controller in the enclosure. P.S. I tried to create SAS-expander as a tag, but my rep on this site is low.

• write-through RAM disk, or massive caching of file system?

  - by Will

  I have a program that is very heavily hitting the file system, reading and writing randomly to a set of working files. The files total several gigabytes in size, but I can spare the RAM to keep them all mostly in memory. The machines this program runs on are typically Ubuntu Linux boxes. Is there a way to configure the file system to have a very very large cache, and even to cache writes so they hit the disk later? I understand the issues with power loss or such, and am prepared to accept that. Crashing aside, in normal operation the writes should eventually reach the disk! Or is there a way to create a RAM disk that writes-through to real disk?

  So there's a notebook (Lenovo Thinkpad Z61m) with a SATA hard disk, the SATA controller is configured for native AHCI operation & the OS is Windows XP. The hard disk is going to be replaced with an SSD which is larger. I have an idea of how I'm going to do this, but I want to be sure there isn't something obvious I'm missing. Connect external USB drive Boot some flavour of Linux live CD Use dd to clone the SATA disk to the external drive Power off and replace the SATA disk with the SSD Boot the live CD Use dd to clone back from the external drive to the SSD Does anyone have anything to add?

• What does the "Maximum Frequency" number mean in the Windows Resource Monitor?

  - by nhinkle

  In the Windows Resource Monitor's CPU tab, there is a status box and graph for the "Maximum Frequency", right next to the "CPU Usage" values. What does this mean? The value is sometimes over 100% on my system... what could that imply? By looking at CPU-z's real-time report of the processor's clock speed, it seems to be loosely related to what frequency the CPU is running at, which would imply that it means "percent of maximum possible frequency the CPU is running at"; this would be of relevance on systems with SpeedStep and/or TurboBoost technology (or similar). Furthermore, setting the system to "power saving mode" lowers the "maximum frequency" value to around 60%, while setting it to "high performance" mode sets it to around 110%. However, the percentage does not seem to exactly correlate to the CPU speed being shown. What value is this actually representing then?

• USB ports not recognizing devices (vista)

  - by frank

  I'm trying to fix a problem on a Vista machine where all the USB ports seem to have power but they don't recognize devices plugged into them. It seemed to start after I plugged my mp3 player (sansa clip) into it and disconnect it. So it sounds similar to this article http://support.microsoft.com/kb/817900 but that was for XP. And I did try all the fixes (including the registry entry) but they did not help. It also sounds similar to this SU question 50110 but I don't think it is the mother board. I have see other places that suggest reinstalling the OS...but that seems like a last resort type of thing. I have also seen a suggestion of doing a system restore but not sure if that will help. Any ideas of what I can try?

• Emacs and Dvorak

  - by Nate

  I'm a dvorak typist and a vim power user, and I'm just starting to do some heavy development in a LISP and I figured I'd give emacs a shot. The trouble is, some of the commands are awkward on dvorak. How do I swap commands around? At the moment I'd like to make C-k act like C-x, C-t act like C-k, and C-x at like C-t, but I'm sure that I'll want to swap more things around as I learn what key combinations I actually use. I know that there are some emacs dvorak modes, but most of them remap all of the commands such that you can keep the qwerty bindings: however, I don't know the qwerty bindings, and most of the bindings are mnemonic, so I'd rather not use any of those. Thanks.

• How to run a service as a user who can't delete or update or create a file

  - by neeraj

  Mongodb is a web based console to try out Mongodb. I have created something similar to try out nodejs. In nodejs I am accepting user input and then I am performing eval on that command. Given the power of nodejs , someone from web console can create a file, delete files on the system or could execute 'rm -rf '. I was thinking will it be okay if I run node as a user called node. This user node will not have any privilege to write anything, create anything or update anything. The only access this user will have is read access. Will that work or that is too much of risk. What is a good strategy to handle such a situation?
