• migrating storage to a different controller

  - by bellocarico

  Hello, I've just purcheased a couple of adaptec controller (2405/5405) for my ESXi 4.0 U1 servers. Currently ESXi and a couple of VMs are hosted on single sata boot disk connected to a nvidia on board non-RAID controller. I know that it's possible to migrate from single disk to RAID 1 with adaptec and I'm pleased with that, but I'm not sure if ESXi has already the right drivers installed/loaded for this controller. Is there any way I can check this? Is ESXi clever enough to recognize the new hardware and load the right module? Thanks

• Setting up Mac VPN on simple network with separate IPs

  - by Dave

  Hi there, We have a pretty simple network configuration. A typical ASDL line with two extra IP addresses. We have a basic home network router Dlink DIR-655. We have two Mac OS X Snow Leopard Servers that we want to setup VPN on. The problem is that we can't change the ports which VPN works under ie. we can only setup port forwarding for UDP 500,1701,4500 to a single server. I'm wondering how we can cost effectively re-work our network so that we can take advantage of the separate IP addresses and have both VPNs working with the same router. Is that possible with our current hardware setup or do we need something more powerful? We're also toying with Mobile Access and wondering if that might be easier to setup. Expert help is greatly appreciated.

• 2 HDs in RAID 1 with 2 partitions ?

  - by Prix

  Hi, i am not very familiar with raid partitons and am not even sure if this is the right place to ask about it, but i hope that if it is not that some one can point me on the right direction. This is my situation, i have 2 500 GB hds and a 3ware pci-e hardware for raid and i wanted to make a RAID 1 but i dont know if i can make more then one partition for it, for instance: MAIN HD: os partition: 100GB data partition: rest of left size and make the RAID 1 either work on all the HD or just on the data partition of it. that is on windows xp sp3 and the 3ware allows bootable raid.

• Best Server Ghost-Like Tool For Windows

  - by John Dibling

  I'm looking for advice on which tool we should use to clone servers. In the short term, we will be cloning identical hardware but in the long run we may want to create one image and replicate that on a different class of machine. For example, as new servers are released from Dell, we will want to continue to use the same image we already made. Right now our servers are Windows (Server 2008 & Server 2008 R2), but moving forward we may need Linux support as well. Ghost Solution Suite 2.5 seems to be the canonical tool. Are there alternatives? Recommendations/reviews?

• PC cannot see Clonezilla server when using PXE Boot

  - by r2b2

  Hi I have about 15 workstations, all have the same hardware specs so I figured clonezilla is perfect for cloning them. So I followed everything this guide says :cloning groups of school computers That guide above makes it all look easy but when I tried setting up Clonezilla Server Edition on my laptop (Kubuntu 10.10) and configured the master computer for PXE boot, the master computer could not see the Clonezilla server. It just shows 'DHCP...' which seems it trying to grab an IP address but to no avail. Please help. Thanks!

• Sound card issues (High Definition Audio Controller)

  - by Prakash R

  I have a 5-year-old Acer Aspire 4520. Until a month back it was working beautifully on Windows 7 32bit. But then out of the blue, the sound stopped working. I've tried reinstalling the OS 3-4 times. The sound came back a couple of times, but it stopped working after a reboot. Even after installing the sound drivers, I don't see any entry in the Playback tab of the Sound applet in Control Panel. I see a High Definition Audio Controller entry in Device Manager. I disabled and uninstalled it, but Windows reinstalls it automatically. I'll share specific hardware details if anybody here needs to know. The processor is "AMD Athlon(tm) 64 X2 Dual-Core Processor TK-55". Any help would be appreciated.

• Windows 7 on 1st Gen MacbookPro Unibody (Q4-2008) - power problems.

  - by typemismatch

  I have the first generation macbook pro, purchased Q4 2008. I've been trying to run Windows 7 and can get it all installed great with the BootCamp 3.1 64 bit drivers however ... power management isn't great. The screen and keyboard don't automatically dim - the laptop gets too hot. I noticed on some newer macbook pros that windows 7 works perfectly and the above doesn't happen. Does anyone know if there really is a hardware issue with this 1st gen or is there some firmware update I can use to fix this? Thanks!

• openSuse full disk encryption

  - by djechelon

  I'm a proud Suser. I'm about to reinstall 12.2 on my ASUS N76VZ (UEFI x64 laptop). Since I'm very sensitive about laptop security against theft or unwanted inspection, I chose to use BitLocker with USB dongle in Windows 7. When installing Suse the last time I found that only the home partition (separated from root) was capable of being encrypted. Does Suse offer a full disk encryption solution like BitLocker that I haven't discovered yet? Or is encrypting home partition the only way to protect data? Encrypting only home is feasible as one stores personal data in home, but I still would like to encrypt the whole thing! Also, using a hardware token (no TPM available) for unlocking is preferred to password, if possible! Thanks

• RS-232 vs. RS-485

  - by user60524

  Doing a little research on the two to figure out which one may better suit my purposes (communications amongst different hardware). How do they fare against one another? Im far from being a specialist and have no idea where I would even start looking for data to compare and contrast. If possible can someone please answer the following questions in regards to each of these. Can they be networked amongst each other? Can they be easily networked over ethernet? What speeds do they transfer at? (Min, Max, Etc.) Reliability? Best framework to build on top of to support the above? Any standard communications programs? Debugging capability? Any help would be very much appreciated, thanks.

• difference between server and desktop

  - by user1241438

  I want to set up a webserver. I would like to buy a hardware for that and i am trying to understand if i should buy a desktop and host the webserver on that or do i have to buy some used server from ebay and host on it. Example is http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=180986172861&ssPageName=ADME:X:RTQ:US:1123 But what is the difference in desktop and server? These days even desktops are coming with high RAM. Only other difference i see is servers have RAID HARD disk. Is there any other difference?

• Do all domains on the same shared hosting server have the same IP or ID

  - by silow

  Here's what I've got: siteA.com and siteB.com are hosted on hostgator. They're hosted on the same account of a shared hosting server (not VPS or dedicated). script.php is an external site that each of these 2 sites are accessing. I noticed that when siteA.com or siteB.com access the outside script.php, the script identifies them both as 1a.12.12ab.static.theplanet.com (apparently because hostgator uses theplanet.com servers). The fact that they're identified as the same value isn't surprising because after all they're hosted on the same account /home/user123/public_html. What I'm wondering about is how about other websites that are hosted on the same shared hosting server, but under other accounts. Basically other websites that are under another developer's control, but just happen to share the same hardware (hosting server). Do they also have the exact same identifier 1a.12.12ab.static.theplanet.com or that changes by account?

• Can I use CAT 6a connectors with 7a cable (and get 6a performance)?

  - by Mr. Flibble

  I'm re-wiring a building and want to get the best cable possible laid - it required re-plastering to make a change to the cables and the cables will be there for the next 10 - 20 years. Currently there appears to be cat 7a cable available but not too much in the way of cat 7a connectors. Also - I won't be using 40Gig hardware in the near future. So, my question: is it possible to use cat 6a connectors / patch panels with cat 7a cable and get the same performance as I would had I used cat 6a cable? Are there any gotchas in trying to do this?

• What do you do with a 15 node decommissioned Itanium cluster?

  - by Gomibushi

  We are decommissioning a 15 node Itanium cluster. We don't know what to do with it. Being geeks we want to put it (or its individual nodes) to some cool use, but since it is Itanium we are a bit unsure what that could/would be. We are not bringing it back as production servers and we are considering giving them away, if anyone wants them. It's not the most spiffy hardware, but being 2U rack servers they pack an ok amount of cpu and memory, they're about 3 years old perhaps. Ideas to what runs well on them? Or something one can use them as?

• How do I fix "Setup did not find any hard disk drives installed in your computer" error during Win XP Pro install?

  - by CT.

  I just bought a nettop. It came with WinXP Home. I first installed Win 7 on it. I wasn't that happy with the performance so I decided to go back to XP. I am using an external dvd drive and a Win XP Pro disc. I boot from the dvd drive and during the install get this error: Setup did not find any hard disk drives installed in your computer. Make sure any hard disk drives are powered on and properly connected to your computer, and that any disk-related hardware configuration is correct. This may involve running a manufacturer-supplied diagnostic or setup program. Setup cannot continue. To quit Setup, press F3. This is the nettop in question: http://www.newegg.com/Product/Product.aspx?Item=N82E16883103228

• How to Virtualize an OEM windows install.

  - by jumentous

  I've bought a new computer and like always it comes with windows 7 pre-installed. I'm a linux user by default but i still keep a virtual windows installation around. Is it possible to install my linux distribution, and use the OEM license that came with the computer to create the virtual instance? I have no intention of moving the license off the physical machine so i'm sure i could argue that i'm not violating the license but i don't expect that this would work and activate without great legal battles. So in the event that this doesn't work what other options do i have? Can i shrink the physical partition and have Qemu boot it? My thoughts are that windows would detect the change in hardware and fail. What can i do with this windows install as a linux user?

• How do I stop someone from saturating my line & wasting CPU cycles

  - by JoshRibs

  My web host shows inbound & outbound traffic with mrtg. I have a steady 3.5mbps inbound traffic from Nigeria. Even assuming the source IPs & destination ports are blocked with Iptables & verifying nothing is listening on those ports, will the traffic still always pass through the switch & "get" to my server (where my server wastes CPU cycles "dropping" the packets)? Assuming I was setup with a hardware firewall, the traffic would still show in mrtg assuming the firewall is behind the switch? So is there any way to stop someone from saturating your 100mbps line, if they also have a 100mbps line? Other than filing an abuse complaint with the kind folks in Nigeria?

• OpenBSD Routing Problem

  - by Ozkan SENOVA

  I am running OpenBSD on a network appliance hardware. It has 5 NICs. I want to give different IP's in same subnet to 3 nics. Eg: em0: 192.168.1.5 em1: 192.168.1.90 em2: 192.168.1.56 I make the necessary configuration with ifconfig, all interfaces works as expected when all the ethernet ports are plugged in to switch. But there is something wrong in routing. If I connect to 192.16.1.5 via any service(http, smtp etc.), traffic goes over link#3. If I unpug the cable from em2 I can't reach any IP's binded on device. Is there any way to route traffic over different links in this IP configuration?

• MediaPortal crash when scanning my TV Channels

  - by Martin Ongtangco

  I tried installing MediaPortal on my old system. I installed & tried both beta & stable releases: Here's the old system specs: Windows XP SP3 512MB DDR 80GB IDE K-World PVR-TV7131 Analog TV-Tuner Inno3d FX5500 128MB 64bit When scanning through the TV-Server, it crashes. I don't know if the incompatibility comes from the hardware or the OS, but my TV Tuner's own Media center app works well. For now, that's what im using. Anyone here familiar with MediaPortal? Thanks!

• Installing FreeNAS 8.3 problems

  - by osij2is

  I'm trying to install FreeNAS 8.3 on some desktop-level hardware (AMD Phenom + 890FX + 16GB) and I've been unsuccessful. I initially tried using a USB stick and followed the instructions on the FreeNAS site here. Making the USB was simple as the instructions laid out, but as soon as the USB is detected (during the boot process) some text appears and quickly vanishes and my machine reboots infinitely. After trying several different was to make the USB, I tried using a DVD-ROM but again, I had the same issue as the USB stick. This leads me to conclude that either a BIOS setting is incorrect but I have no idea which one. I've changed the BIOS to not "fast" boot per se, and I've correctly configured the boot order per USB stick and the DVD-ROM drive so I know that it's working. Have I missed anything that might be causing this problem? I'm not a FreeBSD/FreeNAS expert by any means.

• How does a winkydink Teradici offer high res, full FPS, 3D rendering on ESXi 5 VDIs for AutoCAD/SolidWorks/1080p YouTube applications?

  - by BlueToast

  How does such a small Teradici card ![enter image description here][1] offer high resolution, full FPS 3D graphics (1:38) http://www.youtube.com/watch?v=eXA4QMmfY5Y&feature=player_detailpage#t=97s for ESXi 5.0/5.1 VDI environments? We're shooting for an AutoCAD/SolidWorks/YouTube 1080p capable environment. I can't see how such a small and low profile card could possibly have the horsepower to handle such GPU computations for a big environment like that. We're going to have up to 64 VDIs per server, and are a 500-1000 employee count sized company. Someone enlighten me please! Determining which route to go (between RemoteFX and VMware View/PCoIP) and the hardware (NVIDIA 4GB non-Quadro/Tesla GPUs vs Teradici card). Servers have three 4x, three 8x, and one 16x PCI-E lane. Two of the 8x lanes will be occupied by SAS RAID cards.

• Connecting to Aerohive AP's from Laptops running Win. 7 using authentication from a Windows 2008 domain server

  - by user264116

  I have deployed a wireless network using Aerohive access points. 2 of them are set up as radius servers. I want my users to be able to use the same user name and password they use when they log onto our domain. They are able to do this from android devices or computers running Windows 8. It will not work on Windows 7 machines. How do I remedy this situation, keeping in mind that the machines are personal machines not company owned and I will have no way to change their hardware or software.

• Why does booting from a 64 bit Win 8 USB install work on a 32 bit laptop?

  - by Arabella

  I upgraded a 64 bit Windows 7 laptop to Windows 8 through the Upgrade Assistant, creating a bootable USB without any problems. I installed it successfully. Before I purchased an upgrade for my 32 bit Windows 7 laptop, I decided to boot from the USB with the 64 bit ISO to see what happened. The Windows 8 install screen came up with all the options. Should it not have detected that the laptop is 32 bit and therefore the install should have given an error? I cancelled the install before it did anything, but now I want to know if I need to download the iso again after purchasing the upgrade on my 32 bit laptop? I've read the answers to this question, which confirms what is said in this article - a 32 or 64 bit iso will be downloaded depending on the hardware of the computer you are upgrading. If that is the case, then why did it boot into the install screen?

• some keyboard keys not working properly

  - by surfmadpig

  I'm using windows 7. All of a sudden, a couple of hours ago, this happened: My keyboard number keys [above the letters] stopped working properly, both as numbers and as symbols. Only 5 and 6 are functional. Also, I've noticed that the End key isn't working either, and perhaps a couple more from that group. I'm pretty sure it has something to do with those evil Sticky Keys/Filter Keys/ whatever those ease of access things are, BUT I've turned off all the ease of access keyboard options and nothing has changed. Is it possible that something is still turned on while I unchecked it? Are the on/off checkboxes to control WHEN it happens or IF it happens? I also tried rebooting and uninstalling/reinstalling keyboard from device manager, to no avail. It's certainly a software issue and not a hardware issue, as I've tried another keyboard and the problem persists. And, predictably enough, it's annoying. Any ideas?

• What should a hosting company do to prepare for IPv6?

  - by Josh

  At the time of writing The IPv4 Depletion Site estimates there are 300 days remaining before all IPv4 addresses have been allocated. I've been following the depletion of IPv4 addresses for some time and realize the "crisis" has been going on for many years and IPv4 addresses have lasted longer than expected, however... As the systems administrator for a small SaaS / website hosting company, what steps should I be taking to prepare for IPv6? We run a handful of CentOS and Ubuntu Linux systems on managed hardware in a remote datacenter. All our servers have IPv6 addresses but they appear to be link local addresses. Our primary business function is website hosting on a proprietary website CMS system. One of my concerns is SSL certificates; at the moment every customer with an SSL certificate gets a dedicated IPv4 IP address. What else should I be concerned about / what action should I take to be prepared for IPv4 depletion?

• SharePoint 2010 and Excel Calculation Services

  - by Cj Anderson

  I'm curious what the requirements are for Excel Calculation Services in Sharepoint 2010. I found an architecture document but it doesn't list out the specific requirements. (architecture I understand that you can install all the services on one server but it isn't recommended. It then talks about how you can scale up the application servers, and web front ends. What should the hardware look like for both the application server and web front ends? Do I need to setup a standalone box for each application server?
