• Windows Vista: Screen remains darkened for 30-60 seconds *after* UAC prompt

  - by sf2k

  Fixing someone's Vista computer. Process: I click any program or process that opens a User Account Control prompt. Screen goes dim so you may hit Continue to perform a secure user action. I click Continue Screen goes black for 30 seconds to 1 minute while you wait for the screen to return. In another example I click Cancel and screen still then goes black for 30 seconds to a minute. In that timeframe a chime goes off while you wait. (No chime if it was being cancelled.) Then screen comes back to continue with whatever. Something is occurring after the UAC prompt. Considering everything is practically a UAC acceptance this can get pretty annoying pretty quickly. Laptop has external monitor to regular external plug. Works fine. Laptop also has USB IOGEAR additional external video card. This is problematic but when unplugged same above behaviour occurs. I've ruled out monitor interference since same blackout after the UAC prompt appears with external monitors plugged in or when rebooted with no external monitors. Any suggestions on how to address this problem?

• Using bind (named) as a public proxy server

  - by TrentDavis

  We have a Python DNS server that does a bunch of stuff to figure out values it should return for various DNS records. This works nicely, however as it is Python, the performance under high load won't be great. What I would like to do is have a "proxy" bind server sit in front of it to return results to the public internet. This will cache the results (typically 15 minutes, some records are a few seconds), so the load on the Python server will be greatly reduced as it will only see one look up per domain (only about 100 domains) every 15 minutes. The data in these domains changes a lot, so using a master won't work as it will constantly be changing. I have something setup that looked like it would work great (using a forwarder for the zone), and tested it with dig etc, all going great. However when we went to go live with it, things weren't working, and we figured out that named is not setting the "Authoritative" bit (fair enough, it is a forwarder). So my question is, can we tell bind to set the Authoritative bit for forwarded domains? I have looked at all the doco I can find, and can't find anything about doing things this way. Most of the doco about using it as a proxy if for a LAN to the internet. Ideally I would like to use bind as it is there and installed (CentOS 5 servers). But at a pinch we could look at a different name server to do the work if it just can't be done with bind. Thanks.

• "postgres blocked for more than 120 seconds" - is my db still consistent?

  - by nn4l

  I am using an iscsi volume on an Open-E storage system for several virtual machines running on a XenServer host. Occasionally, when there is a very high disk I/O load on the virtual machines (and therefore also on the storage system), I got this error message on the vm consoles: [2594520.161701] INFO: task kjournald:117 blocked for more than 120 seconds. [2594520.161787] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. [2594520.162194] INFO: task flush-202:0:229 blocked for more than 120 seconds. [2594520.162274] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. [2594520.162801] INFO: task postgres:1567 blocked for more than 120 seconds. [2594520.162882] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. I understand this error message is caused by the kernel to inform that these processes haven't been run for 120 seconds, most likely because a disk access to the storage system has not yet been processed. But what is the effect on the processes. For example, will the postgres process eventually write its data when the storage system is idle again after a few minutes, so that all data is still consistent? Or will it abort the write, leaving some tables in an inconsistent state? I certainly expect that the former should be the case - if the disk access is slow, postgres (or any other affected process) should just wait as long as it takes. I can live with the application hanging for a few minutes. But if there is a chance for data corruption then any of these errors is really bad news. Please advise what to do here.

• Ubuntu 11.10 Virtual-box Unity 3D not working

  - by naveen

  After struggling for four hours, I still cannot get Unity 3D of Gnome 3 to work on my VirtualBox - I have been pouring through Internet and forum posts but to no avail. Here's what I've done so far: VirtualBox 4.1.4r74921 on Windows 7 Installed Ubuntu Desktop 11.10 ( 32 bit ) Enabled 3D acceleration Allocated 1.5GB of RAM Allocated 50MB video memory (hope this is not the culprit) Installed Guest edition 4.1.4 Did apt-get update and apt-get upgrade Booted back in to Ubuntu - falls back to Unity 2D Shared folder, mouse integration all works, so guest edition is properly installed Tried the command and below is the output /usr/lib/nux/unity_support_test –p OpenGL vendor string: Mesa Project OpenGL renderer string: Software Rasterizer OpenGL version string: 2.1 Mesa 7.11 Not software rendered: no Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: no GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no I am trying to find what the "no" means but cannot find any good answers. Inter Core i5 processor 4GB of RAM on the host Display adapter: NVIDIA GeForce 8400GS Is anyone else facing the same problem? If so, can you point me to a solution or any reference where I can find a solution?

• Windows 7 Media Center PC not displaying MKV files properly

  - by David

  Does anyone know why Windows Media Center wouldn't correctly display a 16x9 video? I just upgraded my home-built HTPC from Vista Ultimate (hey, it was a giveaway) to Windows 7 Ultimate - clean install. After that, I installed the Divx7 beta (to get .MKV support) and AC3filter (so I could HEAR the MKV files). Previously, under Vista Ultimate (32 bit), I had Arcsoft's Total Theater Pro for playing Blu-Rays and MKV decoding under Media Center. Now when I play a 720p 16x9 MKV file, I get some 'letterboxing' - like it's halfway between 4x3 and 16x9 - with the aspect ration looking alightly squished as a result. Here's the wierd part. If I use the Media Center connection software in my XBox 360 - it plays perfectly, filling the 16x9 screen edge-to-edge, just like Vista's WMC software USED to. Of course, beats the network up because the XBox goes to the HTPC, the HTPC goes to my WHS machine to fetch the data, it comes back to the HTPC, gets transcoded and streamed back to the Xbox. I'm running the latest drivers for an NVidia card (as fetched by Windows 7). I have no idea WHY this is because if I play "ordinary" (i.s. SD) Divx files that are 16x9, they play just fine, scaled right up to my screen's edges. It puzzles me as to why the same machine that properly converts the bits for the Xbox can't display/scale them properly for the attached display. Mind you, Windows Media Player exhibits the same symptoms. Ideas?

• Remote server security: handling compiler tools

  - by Gonzolas

  Hello! I was wondering wether to remove compiler tools (gcc, make, ...) from a remote production server, mainly for security purposes. Background: The server runs a web application on Linux. Consider Apache jailed. Otherwise, only OpenSSHd faces the public network. Of course there is no compiler stuff within the jail, so this is about the actual OS outside of any jails. Here's my personal PRO/CON list (regarding removal) so far: PRO: I had been reading some suggestions to remove compiler tools in order inhibit custom building of trojans etc. from within the host if an attacker attains unpriviliged user permissions. CON: I can't live without Perl/Python and a trojan/whatever could be written in a scripting language like that, anyway, so why bother about removing gcc et al. at all. There is a need to build new Linux kernels as well as some security tools from source directly on the server, because the server runs in 64-bits mode and (to my understanding) I can't (cross-)compile locally/elsewhere due to lack of another 64-bits hardware system. OK, so here are my questions for you: (a) Is my PRO/CON assessment correct? (b) Do you know of other PROs / CONs to removing all compiler tools? Do they weigh in more? (c) Which binaries should I consider dangerous if the given PRO statement holds? Only gcc, or also make, or what else? Should I remove the enitre software packages them come with? (d) Is it OK to just move those binaries to a root-only accessible directory when they are not needed? Or is there a gain in security if I "scp them in" every time? Thank you!

• How to check DVD region settings in Window 7

  - by jmatthias

  I have installed Windows 7 on my laptop. When I put a movie in the DVD drive, the video player starts up and tells me 'THIS DISC IS NOT FORMATTED TO PLAY IN THIS REGION'. I have changed the DVD region a few times in the past but while I was in Windows XP I changed the region in Region 1. I cannot find how to check the DVD region setting in Windows 7 (it's not located on the hard properties page of the DVD anymore. Does anybody know how to check the DVD region in Windows 7? Update: If I connect an external USB DVD drive I can see the DVD region tab on the hardware properties dialog. I guess there is some compatibility problem with my internal DVD drive and Windows 7 (as I said I was able to inspect/change the DVD region in Windows XP). Solution: I think I had used LtnRPC in the past to remove the region from my DVD drive. It looks like Windows 7 does not like region free DVD drives (at least mine anyway). I was able to use LtnRPC to reset the region back to 1. I can now see the region tab on the DVD drives hardware properties.

• Server reporting incorrect mime type for css files

  - by Becky

  We have a VPS server that we host our websites on. I have written a CMS using CodeIgniter. On one of the interfaces, I am attempting to upload a css file to the system. This worked correctly when we had it hosted on shared hosting. Since we've moved it to the VPS, I am getting an "incorrect filetype" error. It all comes down to the fact that the server is reporting a mime type of text/x-c for the css file rather than text/css. I logged in via shell and ran the following command on an existing valid css file (to make sure it wasn't an issue with either CodeIgniter or with php). file --brief --mime 'filename.css' 2>&1 The server gave me the following in response to my command: text/x-c; charset=us-ascii My question ... is there some sort of server setting that I need to tweak to get the server to correctly identify the css file as text/css? Do I just have to add a mime type for the css files to the server? I found the mime types file (etc/mime.types), and it just hase video types and a couple other that I have no idea what they are. There is nothing in there for css or images or html files. Unless I'm looking in the wrong spot. I'm not a server person, so I'm hoping someone can help me out. Some server specs: Apache/2.2.22 (Unix) php 5.3.13 Server API = CGI/FastCGI the fileinfo php extension appears to be disabled

• Ubuntu rm not deleting files

  - by ILMV

  My colleague and I have been struggling with deleting a directory and its contents. We are working on a new version of our websites source code on Ubuntu 8.04 (dir: /var/www/websites), what we want to do is delete the websites directory and recreate it from a .tar backup we created a couple weeks ago. The purpose of this is so we can run our deployment procedure in a local environment before we do so on our live / public environment. We use this command: rm -r websites This deletes the directory and the files within it. The problem occurs when we un-tar our backup file and view the website we are getting files that don't exist in the .tar backup, in fact these files were only created a few days ago and should have been deleted. We delete the directory once more in the manner stated above, we then create a new websites directory using the mkdir command. Strangely at this stage the 'deleted files' do not come back, but if we unpack our .tar file the 'deleted files' appear again. Is there a way to ensure these files are deleted, or at least the pointers that associate them with said directory. Our .tar backup does not include these files We do not want to use the shred command We do not want to use 3rd party applications Solution should be functional via terminal (SSH) Many thanks! EDIT Er... we fixed it. Turns out the files that are reappearing are because of a link we have to another directory (outside the /var/www/websites), we were restoring the link but not deleting the files on the other end. D'oh! Many thanks for your help guys... friday afternoon syndrome :-)

• SQL 2000 Backup/Export Process - Can't find SQL 2000 Enterprise Manager, Can't use Mgmt Studio Expre

  - by 1nsane

  I need to make a backup of a client's SQL 2000 database, however there are a few issues preventing me from doing so using the traditional methods. I've tried using SQL Management Studio Express, but the host doesn't give sufficient privileges to create a backup and I'm getting some strange error messages. I've also tried doing the "Generate Scripts" to recreate the schema, then using the DTS Wizard to migrate the data, but the IDs set up with the identity specification property are not consistent with the live database once copied over. This results in some foreign key breakage... If I remember correctly, I was able to use Microsoft SQL 2000 Enterprise Manager to perform the task before, but I can't find this anywhere... it seems Microsoft has pulled most SQL Server 2000 stuff from their site. Does anyone know where I can find a copy of Enterprise Manager (or a trial of SQL Server 2000, which I believe comes with the component)? Or conversely, does anyone know of any other tools (preferably non-commercial) that are capable of mirroring remote SQL Server 2000 DBs? Thanks!

• New virtualization project and old SAN

  - by Chris

  Hi, We'll start shortly a partial virtualization of our infrastructure and consolidate a dozen servers into virtuals instances. We'll also add some client application virtualization into the mix for good measure. Two HP DL 380 with the new xeons 56xx and 96 GB of memory each running xenserver + xenapp will then take charge of most of our IT needs. So far, so good. One element that is missing from the picture is the storage part. We need some sort of shared storage to enable live motion and other HA features. We have an IBM DS 4300 SAN that we can use for that. But since it's in production since 2005, I'm not sure about such a critical role for a 5yr old part. So my question is: What is the reliability of this kind of equipment after 5 yr ? Can it last 10 yr with no or few problems ? Since our budjet is tight, not buying another SAN will be a big plus. This lead me to another question: FC disks cost an arm and a leg from IBM. When I type the replacement # in google (for example IBM 300GB 15K 4GBPS FC HDD 42D0410), I can find it at a fraction of the price at various sites. So am I stupid to buy from IBM or naive to trust 3rd party reseller ?? Thanks, Chris

• Copying symbolic links and filenames with special characters to NAS

  - by Mr E

  I have a new Western Digital My Book Live NAS. I am trying to copy files from an old drive to the NAS. I'm using Ubuntu 12.04 and I've mounted the drive by browsing the network in Nautilus and choosing a shared folder configured on the NAS. The shared folder is then automatically mounted at .gvfs/files on mybooklive. There are two problems so far: File names and directory names containing certain characters (e.g. : or |). Attempting to copy these results in the error message: cp: cannot stat `/path/to/destination.filename': Invalid argument Symbolic links. In Nautilus I get the error message: Symlinks not supported by backend My questions are: Can I connect to the NAS or configure the NAS so that I can copy my files without this problem? (In case it matters, I don't need Windows compatibility.) If not, what can I do to identify all the problem files? Can I do anything to automatically fix my filenames Please let me know if any of this needs clarification. I'm not too familiar with all of this so I may have left out some useful information.

• On Windows XP, Start > Run "My Documents" sometimes doesn't work

  - by Clayton Hughes

  On all of my home computers, I can enter "my documents" into the Start Run prompt and the My Documents folder of the current profile will open up. What's more, I can continue typing subfolders, files, etc. and auto-complete works and it's smart and enjoyable. I can't check at the moment, but I'm almost positive entries like "My Pictures" and "My Music" also go to their correct folders. On my work computers, if I enter "my documents" into the Start Run prompt, I get the following error: "Windows cannot find 'my'. Make sure you typed the name correctly, and then try again. To search for a file, click the Start Button, and then click Search." I can sort of circumvent this by creating a shortcut in my PATH named 'my' that points to My Documents folder, but this doesn't solve the auto-complete option (and it's otherwise imperfect, of course, because "my pictures" or "my music" all direct to the same place. A google search doesn't provide much help on this, although it does identify a poster in 2007 with this same question at another board: http://www.msfn.org/board/lofiversion/index.php/t124813.html (Login required, but Google cache available here: http://preview.tinyurl.com/ygxhwwl) Is this just a limitation of the networks belonging to a domain, or is there some way I can get this functionality back? My documents folder does live in the standard place (C:\Documents and Settings{username}\My Documents), and not on a network drive or anything. It's probably worth adding that the computers are part of some freakish Novell domain thing, too. I'm not in IT here so I'm not too up on the details. Thanks for any help/suggestions!

• What configuration changes can I make to speed up extremely slow Windows VM's in ESXi 4.0.

  - by Shawn Anderson

  I've recently moved from VMWare Server to ESXi 4.0. Running on Dell T310. My VM's have been restored but they are running dog slow compared to VMWare Server. I loaded ESXi 4.0 using only default values. Where are some areas where I can tweak the performance? Even logging onto the VM's can be extremely sluggish. Trying to install software on any of them is a new experience in pain. Dell PowerEdge T310 Xeon X3460 2.80 GHz 32 GB RAM 1 HD (2 TB) I have 16 VM's on this server, but only six or so will be running during my testing. I keep an eye on the Resource Allocation and Performance tabs for the host and I never see CPU or RAM getting anywhere close to pegged. Events tab does show some notices for video RAM issues and some hints on Windows activation issues, but nothing that would point to the sort of sluggishness that I'm experiencing. 1 Windows Server 2008 R2 (64-bit) - 4 GB RAM 1 Windows 7 (32-bit) - 2 GB RAM 1 Vista (32-bit) - 1 GB RAM 3 XP (32-bit) - 1 GB RAM Over to you!

• Strange corruption saving from Textpad 5 within Windows 7-64 VirtualBox VM to shared folder with Mac host

  - by joelarson

  I have a fairly new Window-7 64bit install running in Virtual Box on a MacBook Pro. I'm using TextPad 5 within that environment to edit source files that live on a shared folder that is on the Mac Host. When I save some of these source files, the saved file ends up with some amount of the end of the file repeated one or more times. For example, a file that has this at the end: ... return ttp; }; would, once saved, open up with: ... return ttp; }; }; It is definitely a problem with how the file gets written as opposed to how it's read, because I can see this now matter what app I use to open the file with (NotePad & Word in Windows 7, TextWrangler back in the Mac). I've tried saving as ANSI and UTF-8, and with or without the 'Write Unicode and UTF-8 BOM' checked in TextPad preferences. It doesn't happen with all files though I can't see any pattern about which files do or don't have the problem. It doesn't happen with files written to the Windows 7 c:\ drive. And so far it doesn't happen from other applications saving files, only TextPad. Any ideas? My versions: Textpad 5.4.2 Windows 7 Professional 64-bit, fully up to date VirtualBox 4.0.8 r71778 OSX 10.6.7

• What parts should I get for an ASRock x58 Extreme motherboard

  - by Brad Gilbert

  I just received an ASRock x58 Extreme motherboard, for my post on this question. It was a 2009 Tom's Hardware recommended buy. It is a Core i7 motherboard, with an X58 Express Chipset. It uses DDR3 RAM. What I want to know is, what parts should I get to finish it off. I'm looking for some good bargains, because of a lack of funds. The most taxing game I will probably play on it is OpenTTD. The only parts I currently have that are compatible: A Dynex 400W power supply. It appears to be an ATX 2.1 power supply, with the addition of a -5 rail. Apparently designed to be compatible with most ATX-style motherboards. Several PCI add-in cards. Mostly 10/100 Network cards Some sound cards Some video cards with a VGA connector Plenty of PATA drives. 8 GB - 80 GB Hard-drives A dozen or-so CD-ROM drives, only a handful of them are CD-RW drives. One DVD-ROM drive I have one LCD, with a 15 pin VGA connector, which I salvaged from the dump. The only thing wrong with it was some dead capacitors. It also has a stuck pixel.

• Automatically install driver on headless WHSv1 system

  - by Dan Neely

  I have one of the HP Mediasmart Windows Home Server v1 boxes. It's network port appears to have died a few days ago but the system is not giving any other sign of failure: No activity lights activate on either side of the cable when connected to my gigabit switch; when connected to one of my routers 100 megabit ports the lights turn on but it remains unreachable over the network and my router never lists it as among DHCP clients. I bought a USB-ethernet adapter to temporarily get it back online; but the adapter needs a driver to work which I can't install because the system is headless by design (no video out, no PCI/PCIe slots) with admin access only available via the WHS client or remote desktop. Both of those options require network connectivity and are consequently unavailable. I tried copying the drivers to a flash drive; but Windows either didn't look there or none of the drivers provided were suitable (Win8, Win7, or combined XP and Vista). I've been told that a USB WiFi adapter would have the same driver problem.

• Error message: do not have authority to access this function

  - by Ross

  Hi. I just reinstalled Windows on my computer after getting a virus. I worked with it for a while and everything worked as it should. I then used a backup of the computer that I had made a week or so earlier and copied the backup over my user folder. (That is, I took the folder named "Joe" from the backup drive and copied-replaced the whole thing over the folder named "Joe" on the new Windows install.) To do this I had to work from an Ubuntu live CD because some of the files were in use. Now the problem: After I did this copying my computer says that I have no authority. Anytime I try to access anything that is part of the operating system (Explorer, Personalize, Control Panel, etc) I get an error message that says I don't have the authority to do this. I am able to access things that aren't part of the OS: Chrome, Firefox, my accounting software, Rockbox, but nothing that is part of the OS. I only copied over the User file, so I didn't mess with the registry or anything, so I have no idea why this should be. Does anyone out in cyberspace have any idea? Thank you.

• Poor gaming performance with hyper-v installed in windows 8

  - by SnowCrash

  I am getting very poor gaming performance on my Windows 8 host OS with Hyper-V installed but no guest machines running. For example World of Tanks reports 60-70 FPS without Hyper-V installed and 4-14 FPS with it installed. A similar, dramatic, hit is observed in several other games so the issue is not WoT specific. To make the point clear, I am not trying to run games in a virtual machine. I don't even have a VM running while observing this effect. I simply have the Hyper-V feature installed. My system specs: AMD Phenom II 965 (3.4 GHz) AMD Radeon 6950 2GB (XFX Double D HD-695X-CDFC) 16GB DDR3 1333 AMD 790GX chipset Mainboard (Gigabyte GA-MA790GPT-UD3H) I have tried every AMD driver from 12.8 to the current 12.11beta8, virtualization is enabled in the BIOS settings, the onboard 3300HD video device is disabled in BIOS and I have read the MSDN blog entry here regarding a similar issue in Server 2008 that was resolved in 2008 R2 (and hopefully not regressed in Win 8). I'd like to be able to use Hyper-V for development and testing at home (I am a sysadmin/software developer professionally). If, however, I can't also use my home system for entertainment I'll have to scrap those plans.

• Should I enabled 802.3x hardware flow control?

  - by Stu Thompson

  What is the conventional wisdom regarding 802.3x flow control? I'm setting up a network at a new colo and am wondering if I should be enabling it or not. My oh-cool-a-bright-and-shiny-new-toy self wants to enable it, but this seems like one of those decisions that could blow up in my face later on. My network: An HP ProCurve 2510G-24 switch A pair of Debian 5 HP DL380 G5's with built-in NC373i 2-port NIC LACP'd as one link. 9000 jumbo frames enabled. (Application) A pair of hand-built Ubuntu server with 4-port Intel Pro/1000 LACP'd as one link. 9000 jumbo frames enabled. (NAS) A few other servers with with single 1Gbps ports, but one with 100Mbps. Most of this kit is 802.3x. I've been enabling it as I go along, and am about to test the network. But as my 'go live' day nears, I am worried about the 802.3x decision as I've never explicitly used it before. Also, I've read some 10-year old articles out there on the Intertubes that warn against using flow control. Should I be enabling 802.3x hardware flow control?

• Remote Desktop Session Black after Minimize

  - by TorgoGuy

  PROBLEM: When I minimize a remote desktop session and restore it, the remote desktop screen shows up black. This only happens when connecting to a particular computer. DETAILS: If I start clicking around in the black area, portions of the screen will start redrawing and showing up correctly. For example, if I leave a window open in the remote session and click where that window is located on the remote computer, then that window--and only that window--will redraw, and sometimes a portion of that window won't redraw (usually the toolbar). And to clarify--the window only has to be minimized momentarily, so it doesn't seem to be a timeout issue. Clicking or typing in the remote session still causes the remote computer to respond appropriately. Disconnecting from the session and reconnecting restores the whole screen image, as does clicking all over the place in the black image (causing each section to redraw). CONFIGURATION: This problem only happens for me when connecting to a particular computer (a W2K Server box configured to allow remote administration) and only with certain client computers. I've tried 7 different client computers with various versions of Remote Desktop (the OSes were: Win2K, Server 2003, Server 2008, Windows 7 RC, 3 XP) and two of them exhibit the problem (one is one of the XP boxes and the other is Windows 7). Those same computers can RDP to other computers without problem. RESOLUTION ATTEMPTS: I have tried the following: Disable the LOCAL screen saver as mentioned on Technet Turned off bitmap caching in the client, as mentioned on many forums. Updated to version 6.1 of the remote desktop client Using mRemote (I doubted this would work since it uses MS's code for connecting to RDP servers) Turning off all video acceleration. QUESTION: Any ideas on what is causing this?

• New keyboard for linux: Adesso Tru-Form or MS Natural Keyboard 4000?

  Hi folks! I'm going to buy a new ergonomic keyboard for my laptop. In the following, keep in mind I live in Italy. I considered the following models: Adesso PCK-308UB - Adesso Tru-Form™ Pro - Contoured Ergonomic Keyboard with TouchPad-PS2 Pro: has a built-in touchpad in the same position of my laptop somewhat cheaper than the alternative below Cons: the surface doesn't seem to be bowl-shaped. keys seem to lay on a straight slightly-inclined surface. It seems an idea used extensively in other ergonomic keyboards according to a few comments on the net, new Adesso keyboards seem to lack robustness, they're likely to loose small parts after a few weeks or months. Other users, instead, seem to never had any problem in years and swear by their quality and comfortability. Those who had problems, however, lamented a lack of responsiveness from the manufacturer. I'm not sure whether the keyboard, at least the standard keys, and the touchpad will both be recognized correctly under linux distros (I mostly use FC btw) last time I checked, Adesso didn't have local resellers in my country Microsoft Natural Ergonomic Keyboard Pro: recognized as one of the most comfortable keyboards reliable customer service operating in my country AFAIK there are several documented ways to get extra buttons work with linux Cons: it doesn't have a builtin touchpad and has a numeric keypad wasting space to reach mouse But there could be other keyboards I haven't considered yet, so here follows my ideal keyboard wishlist, ordered by priority linux compatible basic ergonomic design, which entails split tilted keyboard and pads advanced ergonomic design, like true-ergonomic's or kinesis , where special keys (like enter, caps-lock...) are placed symmetrically in the middle to be used by thumbs a builtin touchpad/trackball placed under the keyboard. I just love this on my notebook. I think it's pretty effective, since it allows my hand to rest naturally everytime I use it. Any opinion on this? high-quality switches, like cherry's (unsure about this one) additional programmable keys placed near usual ones, to simplify typing shortcuts TIA Andrea

• What benchmark tool to use to benchmark hardware for VM server?

  - by Mark0978

  We are setting up a new piece of hardware to virtualize several of our servers on. Choices are RAID 5, RAID 6, and RAID 0+1. We are wanting to benchmark all three before we go live with the machine, but I'm not sure how to test the speed. Since we will be using it to host VMs, what will the actual disk traffic look like? What can I use to see if RAID 6 is too slow? Short of setting up the system with all the VM's on it and running that way, then redoing on all the work, I'm not sure how to test it. It them becomes more of a subjective test than an objective one. I'm worried that RAID6 will have too much overhead, that RAID5 will be to fragile with 3TB drives and I've never worked with 0+1 at all. So in short I'd like to setup the base machine (which will be running Linux) and then test the underlying SW RAID for speed. What kind of tool exists to simulate this kind of load? Barring the lack of a specific tool, how about a generic FS testing tool that will simulate different loads?

• Acer Aspire one is falling apart on Ubuntu

  - by Narcolapser

  Question: How do I have my netbook detect and install hardware? Info: I have an Acer Aspire One, it came with windows XP and I loaded it with Win7. I decided I wanted to change to Ubuntu so I tried Ubuntu netbook remix, which failed horribly, and so after attempting 3 or so other OS's I ended with Ubuntu Desktop 9.10. Which worked fine for a while, but there were some minor issues so I asked a question about it here and decided to change my OS again. This last weekend I tried mandriva like that guy in my other question suggested, no success. when I had though my netbook lost the ability to use it's touch pad, I didn't think much of it, just thought it must be a driver or something. But When Mandriva failed, and I also while I was at it tried Damn small linux and Debian, which both failed to, I decided to switch back to Ubuntu Desktop(some where in here my keyboard stopped working for one attempt to). But first I gave the netbook remix one more try. it worked this time, with the exception of it didn't have any networking. I thought it was a driver issue again and finished the weekend with ubuntu desktop 9.10 again. But now things get really crazy. it doesn't know it has a wireless card or an ethernet card. It doesn't know my phone is connected trying to provide wireless broadband either. I'm clueless on what could be the problem. And with only a minimal amount of experience with Ubuntu can't navigate the entire interface with only my keyboard(it doesn't detect a USB mouse when I plug it in, it had when I installed it. in fact the network interfaces were working just fine when I live boot ubuntu to installed it). Even so, I don't know where to go or what to do to make it recognize it's hardware. I'm in a dire situation, any help is welcome.
