• Memory works fine separately, but not together

  - by patersonjs

  I've been given four 1GB Corsair DDR2 memory modules, and am trying to fit them into my computer but am getting BSOD on Windows XP and errors in Memtest86+. I've tried to identify if one particular module is faulty by trying them in pairs. They work fine in pairs, but when all four are inserted, Memtest86+ reports errors. The motherboard is an Asus P5N-E with dual channel support and the modules are all the same model (same speed, capacity and timings) but one pair is a different hardware revision. One is v2.1 and the other is v2.2... the voltages are the same too. Would this minor difference be a possible cause of the problem? I've got the BIOS memory timing settings all at AUTO - should I manually set the timings?

• Top causes of slow ssh logins

  - by Peter Lyons

  I'd love for one of you smart and helpful folks to post a list of common causes of delays during an ssh login. Specifically, there are 2 spots where I see a range from instantaneous to multi-second delays. Between issuing the ssh command and getting a login prompt and between entering the passphrase and having the shell load Now, specifically I'm looking at ssh details only here. Obviously network latency, speed of the hardware and OSes involved, complex login scripts, etc can cause delays. For context I ssh to a vast multitude of linux distributions and some Solaris hosts using mostly Ubuntu, CentOS, and MacOS X as my client systems. Almost all of the time, the ssh server configuration is unchanged from the OS's default settings. What ssh server configurations should I be interested in? Are there OS/kernel parameters that can be tuned? Login shell tricks? Etc?

• How to convert WinXP + Apps on RAID0 to use just one of the two RAID disks?

  - by chris5gd

  I have two 150GB SATA drives in hardware RAID 0, on which I have my C: (Win XP) and D: (installed apps). I'm migrating to Windows 7, but I want to keep my XP system until I've got it all running smoothly. So I want to: break the RAID move C: and D: to one of the drives (there's enough room) use the other drive for Win 7 boot into one or the other Clearly I can't move C: and D: after breaking the RAID, so I'm assuming I need to image the two partitions first, then break the RAID and restore the images to one of the drives. So my questions are: Is this possible? If so, what would be a good (free) imaging/restore tool? How do I ensure that the drive will boot after restoring the images? What sort of gotchas should I look out for? If there's a better solution than this, I'd be grateful for suggestions. Thanks!

• Straight-forward to Virtualise with XEN or KVM on IBM Server System x3650 M4 791562G?

  - by ChrisZZ

  I want to built a virtualised Server Environment using XEN or KVM. The virtual machines should be purely debian systems - so XEN or KVM should be a sane choice. Now while buying servers, I am confronted with the fact, that the vendors obviously only support commercial solution. I think, on a good server, one should be able to install uncommercial software as well - but of course sometimes systems have hardware, that requires drivers, that are not found in the OS Community. So I am asked the question: Is it straight-forward to use Debian with IBM Server System x3650 M4 791562G with Debian - or even virtualising the IBM Server System x3650 M4 791562G using XEN or KVM. I am sure there will always be a way to achieve this goal - but this way might have a high milage - so I am not asking, whether this is theoretical possible, but whether this should be straight-forward and practically easy to do, no major headaches to be expected.

• Strange Intermittent Background Sound in Windows 7

  - by NoCarrier

  Ok, this is very strange. Recently, i noticed that every 10-15 seconds, there would be this faint, annoying duh-dum sound coming out of my speakers. (hard to describe. sounds somewhat like the sound windows makes when you unplug a USB device, but not as pronounced and much quieter). I closed every app and ended as many processes as I could, but the sound persists. I look at the volume mixer and sure enough, when the sound occurs, there is a little spike in the level under "System Sounds". I haven't installed any hardware or software in the last several weeks. This started recently - completely out of the blue. Does anyone have any insight?

• Power outage, Server 2K3 remains on "applying computer settings"

  - by syuroff

  My reward for clicking the "test" button in the APC UPS software was that it completely cut the power to my SQL server. The server promptly rebooted, the SQL service is running (verified by the app on another server that queries it), but the GUI has remained on "applying computer settings" for 20 minutes and counting, and it forbids RDC connections. Since SQL is up, it is fulfilling its key role, but it's obviously not right. What step to take next? Wait longer? Hardware is a Dell Poweredge 2850, internal RAID10.

• Disk controller speed responsible for slow write speeds?

  - by vizvayu

  I have question. I'm using ESXi 4.0U1 in an IBM x3200M2 with an integrated LSI 1064e RAID controller, without any kind of cache. I have 3 250GB HOT-SWAP SATA HDs configured in RAID1E (IME). ESXi works fine, read speed are quite OK, but write speeds are incredible slow, never more than 8MB/s, and this is the best case scenario, benchmarking with iozone streaming writes, using a VMWare Paravirtual controller and with only this VM active, no swapping of any kind (total vm memory reserved). Already wrote to IBM but I don't have any kind of pay support so they didn't even answered, so I'm just wondering... anybody has any experience with a similar setup? I just want to be sure this is hardware related and can't be fixed with some kind of config option, because I'm thinking on buying a new RAID controller (Adaptec 2405 looks nice). Thanks again!

• Cannot Login as root

  - by Josh Moore

  At my work we ship our product on pre-installed servers as a software/hardware package. We are using open SUSE 10.3 for the OS and we setup and we always log in with the root user to do maintenance on the box. Recently we just had box returned to us that the customer said the could not longer connect to the box through the network interface. So when I started to work on the box I run into the this problem: At the command prompt to login i type the user name "root" and hit enter. Then even before it asks me for a password I get "Login incorrect". I have never seen this behavior before and could not find any information about it online. Does anybody know what is going on? Thanks.

• Is there a software like AutoCAD, but only 2D, not 3D?

  - by Saeed Neamati

  I love AutuCAD. It's powerful, easy to use, and fits engineering mind. It rocks when you want to draw 2D diagrams and shapes and one the cool features I like about it, is its snapping power. You draw a simple rectangle, then you can very easily create a circumscribe circle around it. However, new version of it are becoming really heavy (in size) and need high tech hardware, because of its powerful 3D capabilities, and rendering engines coming with it. I only want the 2D part of AutoCAD. Is there any software out there, which resembles AutoCAD (like having a console, where you can type L and get the line tool, or having snapping capability, etc.), but is small in size? In other words, what software can be named as AutoCAD 2D alternative?

• Does Windows 8 Need New, Specialized Drivers?

  - by Synetech

  It seems like an obvious question, but I’m having a difficult time finding out if Windows 8, with all its changes, will require new, specialized drivers. I see that a lot of manufacturers have started releasing Windows 8-specific drivers for their hardware, but what about those that are not, will Windows XP or 7 drivers work or have they changed the driver/system/security architecture again, thus requiring new drivers? The closest thing I could find to an answer was a thread in which it was mentioned that the display driver model was again updated, thus requiring new display drivers, but not much else (e.g., audio cards, printers, chipsets, etc.)

• Raspberry Pi based Hadoop cluster

  - by Dmitriy Sukharev

  Is it at least possible to build Hadoop cluster from Raspberry Pi-based nodes? Can such a cluster meet hardware requirements of Hadoop? And if so, how much Raspberry Pi nodes are required to meet requirements? I understand that a cluster from several Raspberry Pi nodes being cheap is not powerful. My purpose is to organize cluster without possibility of loosing personal data from my desktop or notebook, and to use this cluster studying Hadoop. I'd appreciate if you suggest any better ideas of organizing a cheap Hadoop cluster for studying purposes. UPD: I've seen that recommended amount of memory for Hadoop is 16-24GB, multi-core processors, and 1TB of HDD, but it doesn't look like minimal requirements.

• How can I re-create Microsoft Cluster Service resource groups on a different cluster?

  - by PersonalNexus

  I use Microsoft Cluster Service on a cluster of Windows Server 2003 machines containing several dozen resource groups. In the process of migrating to newer hardware, I would like move resources to the new machines on resource group at a time spread out over a few days to ease the migration and minimize risk. I was wondering of there was a smarter way to do this than manually re-creating resources on the new and then deleting them on the old cluster? The cluster has already been set up properly, the only missing is the resource groups and the resources they contain (IP, network names, services...). I have looked through the options of the cluster admin GUI and cluster.exe's commandline options, but haven't found anything like an import/export feature to copy over the configuration of a resource or entire resource group. Does something like this exist?

• Can't decide on a new distro

  - by Alex W

  I've had Ubuntu (9.10) on my netbook in the past and I really liked it. I'm currently running Fedora and feeling like I should "change it up" again. I've played around with Ubuntu 10.04 Lucid a little, and so far I'm very impressed. I've always wanted to try Arch, but I'm worried I won't have the driver support I need for all the non-standard hardware in a netbook. Does anybody have a suggestion for a new distro to try? I'm preferably looking for something feature-rich over light-weight, and something that I can have up and running with a minimum of configuration (at least partially working). Thanks!

• Why aren't there 8gb RAM modules yet?

  - by user49951

  Why is RAM module development seemingly stuck at the same size for a while now (a couple of years)? I bought 2x2gb modules 2 years ago, and now it's all the same size, with prices even bigger. I want more memory, because I work a lot on my computer and I just need it. What is going on? Hardware/memory progress was being made constantly until these couple of years, and I'm a big computer user for over 15 years. Why isn't here 4gb/8gb modules yet? I would gladly replace my DDR2 motherboard for a DDRX one if it had at least 4gb DDRX modules for a reasonable price. Now we have a situation with very cheap usb drives reaching 64gb size, and a ram modules with pathetic 2gb size. Sounds like some sort of conspiracy.

• Do HTTP reverse proxies typically enable HTTP Keep-Alive on the client side of the proxied connection and not on the server side?

  - by LostInComputer

  HAProxy has the ability to enable HTTP keep-alive on the client side (client <- HAProxy) but disable it on the server side (HAProxy <- server). Some of our clients connect to our web service via satellite so the latency is ~600ms and I think that by enabling keep-alive, it will speed things up a bit. Am I right? Is this supported by Nginx? Is this a widely implemented feature in other software and hardware load balancers? What else besides HAProxy?

• Is it possible to live-boot VirtualBox from a USB flash drive?

  - by bw.

  To clarify, I'm not asking if you can boot from USB from within VirtualBox. I would like to make a portable version of Windows 7 that I can run from a USB drive on any machine. I'm putting a distro of Linux on my laptop, but I manage a Windows domain at work so I'd like an easier management solution than trying to use Linux tools to interface with a Windows DC(as RDP to a DC is not always an option). The reason I'm inquiring about VirtualBox... I plan on carrying this portable installation with me and using it on multiple machines, so I would like to avoid driver conflicts (which I imagine would happen if I only installed Windows on a flash drive). Basically, I need a way to boot an installation of Windows 7 from USB that still allows me to install/remove/update programs as if it were installed on a standard hard drive, and not freak out over different hardware configurations. Please help, superusers!

• Keeping the wireless connected.

  - by casr

  I’m running OpenBSD on a computer which is connected via wireless to the network. It is a well supported NIC and I’ve had no problems with it from a hardware perspective. Unfortunately my wireless access point occasionally loves to forget it’s settings. I then have to help it remember. However, in this intervening time my OpenBSD box drops the connection and then does not automatically reconnect. I have alleviated my problems by running this simple script in the background: #!/bin/sh while [ 1 ] do ping -c1 192.168.1.254 > /dev/null if [ $? = 1 ] then sh /etc/netstart ral0 > /dev/null fi sleep 30 done [Ping the access point. If there is no response attempt to reconnect.] It seems to me to be a very suboptimal solution. Has anyone else come across a better way?

• Web Server Setup

  - by gustyaquino

  Hello, In my workplace, we want to implement your own web server for at leat 100 Apache/PHP/MySQL web pages. My boss is opposed to hiring skilled personnel, he think we can do ourselves. Currently, we are working with hostgator reseller account. I chose CentOS as the operating system, but I don't know the best hardware solution. HP, Dell ? What about the setup on these platforms? Thanks. PS: sorry for my bad english Edit: The purpose of this migration isn't related to performance issues. But independence.

• Hylafax with serial over IP modem

  - by zero_r

  I'm looking into virtualizing a Hylafax server which currently runs on a dedicated hardware running CentOS with a Divalogic card. The main issue obviously is, how to connect the modem to the VM. There are serial over IP devices available at digi.com. Maybe there are others? Regarding digi.com devices, as far as I understood one can install the RealPort software and then have a /dev/ttySx device presented to the Linux server. This device then can be used as serial connection to the modem. Does someone have such a configuration in place? Or does someone have another idea to virtualize a Hylafax server (outbound faxes only). Thank you in advance

• Audio Line-In on Ubuntu/Linux Mint

  - by hahuang65

  I'm currently on Windows, and want to switch to Linux, but some hardware issues are preventing me. Mainly, I have a sound card that supports Line-In. On Windows, anything I plug into the line-in gets outputted to the speakers. However, when I installed Linux, because there is not a control application that comes with the driver, I have no idea how to set this up. I tried going to the sound settings and it doesn't seem to be there. I also want to configure it for 2.1 sound, and do not know how to do that... Anyone here done it before? Thanks in advance for the help!

• Security considerations when giving access to SQL Server db for a web application

  - by rem

  I need to expose our SQL Server 2008 database for an access from a asp.net web application. This is a new task for me, so I would like to know what basic security requirements are there for configuring software and hardware components of web server and DB Server. Is it OK to have both Web Server (Windows Server 2008) with IIS holding ASP.NET application and SQL Server 2008 on the same machine? Should I have to install additional firewall, like Forefront TMG? Should it be on separate computer? In case a web application is hosted on an external web hosting privider server and SQL Server DB on a our internal server what are "pro's" and "con's" of such configuration?

• Sharing files between multiple computers?

  - by Koalatea

  At my school, we have 13 iMacs that we use to make our yearbook. Currently our school has some servers for us, but since we work with so many files ( thousands of pictures, most of which are ~3MB ) it slows down far too much. Is there a way to better share files between our computers? We are on a wireless network and the whole school shares the same servers, we have around probably 400 computers in the school. Is there a hardware fix I can do? Something like buying an external and hooking only yearbook computers to it?

• Software RAID underneath ESXi datastore

  - by carlpett

  I'm building an virtual environment for a small business. It is based around a single ESXi 5.1 host, which will host half a dozen or so VMs. I'm having some doubts regarding how to implement the storage though. I naturally want the datastore to be fault tolerant, but I can't get the funds for a separate storage machine, nor expensive hardware RAID solutions, so I would like to use some software RAID (lvm/mdadm, most likely). How can this be implemented? My only idea so far would be to create a VM which has the storage adapter as passthrough, puts some software RAID on top of the disks and then presents the resulting volumes "back" to the ESXi host which then creates a datastore from which other VMs get their storage presented. This does seem kind of round-about, do I have any better options? From my research, passthrough seems to come with quite a few drawbacks, such as no suspend/resume etc.

• good books about server architecture?

  - by ajsie

  when the traffic for a website grows i dont think one apache server in a vps is the way to go. i would like to know more about how i then should set up the server side architecture. im not that much into hardware stuff (what kind of cables to use, different cpu architectures etc), but interested in the software architecture: what servers (apache, nginx, squid, varnish etc) to use and how they interact with each other one server in one machine? how many mysql servers. how many apache, nginx servers and so on. how the "machine court" looks like. are there any good books about this area?

• migration of physical server to a virtual solution, what i have to do?

  - by bibarse

  Hello I'm new in this forum, so i would like that you forgive me for my blissfully and my low English level. I'm a trainee in company one month ago, and my mission is to migrate 3 physicals servers to a virtualization technology. The company edit softwares for E-learning so there are lots of data like videos, flash and compressed (zip). This is some inventory of the servers: OS: Debian, 2 redhat, apache, php/mysql, sendMail/Dovecot, webmin with virtualmin template to create dynamically the web sites because there is no sysadmin ... The future provider will be responsible of to secure, update and create the virtual machines (outsourcing) and with a RedHat OS's. So i want that you help me to choose a virtualisation technologie (for the i prefer KVM of Redhat RHEV, VMWare is expensive), how evaluate the hardware needs (this for evolution of 4 or 5 years) and to elaborate a good planing to don't forget any think. Thank you for your responses.
