• TV video constantly skips 1/2 second, plays 1 second; green on bottom

  - by Robert

  I just got DirecTV. It worked for a day, but now the TV video constantly skips 1/2 second, then plays 1 second. Also, the bottom 5th of the screen is solid green. The audio does not skip. I tried to do "Set up TV signal" (in Media Center) - but I get an error. See the post I just made here titled "Error - “IR Hardware not detected” - but it’s installed/working." Thanks for your help.

• How to troubleshoot memory card read?

  - by shinjin

  The built in memory card reader in my laptop mounts SD cards as read-only only. This happens both in Windows 7 and Ubuntu. Most of the time. Ever now an then it works. After a some non-deterministic combination of uninstalling/reinstalling/disabling/enabling of the driver with the mandatory reboots the card reader works for a while. Is there any sane way to troubleshoot if it's an actual hardware problem, or just a matter of drivers? I've tested it with several SD cards, that work just fine in other devices. System: Acer Aspire 8951G, Windows 7-64bit

• PostgreSQL disaster recovery options

  - by Alex

  My customer has quite a large (the total "data" folder size is 200G) PostgreSQL database and we are working on a disaster recovery plan. We have identified three different types of disasters so far: hardware outage, too much load and unintentional data loss due to erroneously executed bad migration (like DELETE or ALTER TABLE DROP COLUMN). First two types seem to be easy to mitigate but we can't elaborate a good mitigation plan for the third type. I proposed to use ZFS and frequent (hourly) snapshots but "ZFS" means "OpenIndiana" these days and our Ops engineers do not have much expertise in it, so using OpenIndiana imposes another risk. Colleagues try to convince me that restoring from PostgreSQL PITR backup can be as fast as restoring from a ZFS snapshot but I highly doubt that replaying, say, 50G of archived WALs can be considered "fast". What other options are we missing? Is ZFS an only viable alternative? Can we get a fast Pg DB restore time in the Linux environment?

• Rename Devices in Device Manager

  - by Luke

  This is mostly just for the USB ports, as I recognize everything else in computers.... Anyways, is there a way to rename, or otherwise, identify which USB port (or other hardware for that matter) is which device in Device Manager? I know I can plug in a flash drive, then see what port it is connected with, and find out that way. What I would like though, is to find out that a certain plug is always a certain device in Device Manager. If I can then have a system in mind that always has the same order, I can look and see if a USB port is not being detected or not working properly, and as I uninstall/reinstall USB devices, I know I won't lose my keyboard or mouse, for example. The OS in question currently is Windows 7, but I would accept a solution for ANY version of Windows USB Devices | +--+USB Root Hub Port A | | | ---Keyboard | +--+USB Root Hub Port B | | | ---Mouse | +--+USB Root Hub Port C | ---Empty

• erratic audio levels on windows vista

  - by old retired dude

  I'm somewhat hard of hearing. I've been listening to my windows Vista machine with a pair of headphones so I don't annoy the others. I have 2 issues: 1) the volume varies enormously depending on the source. Having a windows alert occur while I am listening to a DVD or Youtube is a painful experience. Is there a preferred way to set all the different audio controls so I have a more constant volume? I already have lowered the volumes of the windows alerts. 2)Is there a way to limit the volume of my headphones to protect what is left of my hearing? Is there a software solution or should I be going for a hardware limiter? thanks retired dude

• How long do servers usually last?

  - by AX1

  I'm trying to estimate ROI for a new server and how long it will most likely be in service. Are there any average numbers for how long you can expect a server to last that's in 24/7 use? In other words, is it likely to find 10-year old server from 2010 in today's racks? How about servers from 2005? I'd love to get an idea for how long a server will most likely be in use. By the way, this is meant irrespective of growing or changing application needs. I'm talking only about the hardware.

• mirroring linux server to external usb harddrive

  - by DuPie

  My google-fu must be sucking. i havent been able to find a good solution for the following: numerous Linux server on commodity hardware Trying to do a recovery mirror copy to external harddrives External harddrives are smaller than source harddrives, but larger than data External drives are connected via usb2 (slow) Servers range from 20GB of data to 400GB of data Servers are remote, so hands on access is a pain need to copy boot files. empty external drives currently Basicly, looking for a way to do use a ghosting solution from INSIDE a running linux server to an external harddrive, without booting a cd etc. the rsync/cpio solutions i've looked at dont work great with grub/dev/proc etc. I understand that since the system isnt offline, it wont be a "mirror" image as files change, but thats ok. Are there any free/commercial products that would work?

• Web/Cloud Based OS with Torrent Features and Free Storage?

  - by Kristina E

  Hi, I want a web-based OS with a torrent client and I want to link it to one of the many free cloud storage solutions. I think it would be really cool to be able to check and download torrents anywhere and not use my hardware or connection until I want to transfer the files down to my actual desktop (like burning a Linux ISO or to convert the file to a IFO format). Anywyas, I created accounts at 4Shared, EyeOS, GlideOS, ADrive and iCloud and am having no luck. There is an eyeTorrent app but I can't seem to get it configured and I can't log into my cloud storage from the cloud OS. Has anyone been able to pull this off and if so would you please explain how? Thanks, Kristina

• Windows 7 on 1st Gen Macbook Pro (Q4-2008), power management 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!

• Different graphic cards drivers while booting from external media

  - by goran

  I am booting a certain system of mine with ubuntu 9.10 from external HDD. I am satisfied with the setup and it works fine, however I would like to modify it so that I can choose which graphic card drivers to load during the boot time. Specifically I would like to choose between: nvidia proprietary driver ati proprietary driver generic driver Currently if I am using proprietary drivers then dont boot into X, delete xorg.conf, start gdm and reconfigure the system using jockey (for hardware drivers). What would be the steps to make this (semi-)automatic and avoid restarting X?

• Cable installed - now my hub has no connection the router/modem - what do I need to buy?

  - by bcmcfc

  My previous setup was as follows: [modem/router]------[switch]+------ [pc1] +------ [pc2] I've just moved and had cable installed and I no longer have the option of running a lengthy LAN cable from the router to the switch to provide network and internet access to the two PCs. The cable company provided 2 wireless N USB adapters. What do I need to buy to plug into where in order to restore the network to its previous state? PC1 dual boots Windows 7 and Ubuntu 12. PC2 runs Debian 6. Edit: USB adapters - Netgear WNDA3200 Switch - TP-Link TL-SF1008D 8 port Ethernet switch Cabling - various patch cables cat5e rj45 Modem/Router - pretty standard cable company job - wireless Intention is something like- [modem/router] --wifi-- [some-new-hardware or perhaps to pc1] ----[switch]---[pc1/2]

• Netgear VPN can't access specific server

  - by Critologist

  I have a Netgear FVS318N configured with a VPN. I'm trying to access my call recorder with the provided software from another office. I've already setup the VPN connection, and it works. I can connect and ping the remote router and a few other things on the network. However, I can't ping or connect to my call recorder. If I move outside of the office network (i.e. connect directly to the cable modem or via a mobile hotspot), I can connect and ping the call recorder just fine. The office has a simple Linksys WRT54G router and is using AT&T Uverse. The remote location is using Charter Cable with a Netgear FVS318N. Has anyone ever encountered anything like this before? I've setup an identical VPN previously for a different client using similar hardware and never encountered this. Thanks in advance!

• ATI Radeon HD 5970 Display numbering issues

  - by Arindam Sen

  I have 2 computers on which i have ATI Radeon HD 5970 graphics card installed. There is 1 VGA out and 1 DVI out in it. When I connect my VGA out to a monitor on my 1st computer, it shows it as display 1 and when I connect my DVI out to a monitor it show it as display 2 (I am using extended display). When I do the same thing on my 2nd computer it shows just the opposite. The VGA out shows as display 2 and the DVI out shows as display 1. Is it a problem with the drivers or the hardware? (because the graphics card on both is exactly the same)

• Where can I configure wireless to be passed on to the Virtualbox guest?

  - by huahsin68

  I have WinXP install in virtualbox which host in Linux. I have a TP-Link (TP-WN321G) USB wifi adapter and have the driver installed inside WinXP. When I plug-in the wifi adapter, there is an option show "Ralink 802.11g WLAN [0101]" in the virtualbox's USB icon, tick on that option, the Device Manager able to detect the hardware which shows TP-Link, but when look into the properties, it says there is no driver was install. I did try to install Ralink driver but still no luck. Just curious why my wifi adapter is TP-Link, but the option show Ralink? May I know how can I emulate the wireless network inside WindowsXP?

• Setting up Raid 1 Array for Home Server

  - by user1048116

  I'm not sure if this is even possible, but it's worth asking on here! Essentially I have a old machine at home (well, not old hardware wise, but I recently built a new gaming rig), which I decided to install a copy of W2008 R2 on and use as a file/backup server and media center'ish machine. As of now, it has a single drive partitioned into C and D, with D being the Data partition. I have happened to find an old 1TB SATA drive lying around at home, and was wondering if it's possible to setup a Raid 1 array in my rig within Windows without needing to lose everything on my first drive (or maybe even just mirror a specific partition, say the Data partition, as this is just what stores my photos etc). Maybe this isn't possible, but you never know :) Regards, T.C

• Bound external Cisco CIGESM ports to a specific BladeServer

  - by Vinícius Ferrão

  We have an IBM BladeCenter with 14 blade servers and one external Cisco CIGESM for Ethernet connectivity. Since this hardware is a little old, we will use it for other services, and we want to run a pfSense instance on one of the blades. It's just an Firewall Appliance, but it needs two network interfaces: one for the WAN and the other one for LAN access. Our architecture works on top of static routes, we don't use NAT, so we got the WAN IP in one interface routing to the another one. The main problem is how to plug the WAN cable in one of the four external ports and make it exclusive to the blade server containing the firewall. And we also need an exit port that goes through a 3COM 4200G switch that makes the internal routing and VLAN separation. Thanks in advance

• seamless mode remote desktop connection from linux to windows

  - by mateusz.fiolka

  I am a programmer using Linux as my main OS, however sometimes I need to use windows (ie, office, ea). I'm running qemu with kvm to access the windows "machine". I would like to achieve something that is described here: https://help.ubuntu.com/community/SeamlessVirtualization (It means I would be able to run chosen applications on Windows and then display them locally on Linux as separate windows achieving good desktop integration). However seamless rdp is buggy and doesn't work on my machine (probably because I'm using a tiling window manager and a 64bit system). Are you aware of any other solution then rdp seamless mode? I would prefer to still use quemu because it uses cpu hardware virtualization, so different protocol/client combination would be preferable.

• Win 7: Share internet connection via Ethernet and WiFi

  - by Anvaka

  I have the following configuration: Box 1. Running Win 7, connected to the Internet via Eth0. Has one wireless network adapter and one another ethernet adapter (say, Eth1). Box 2. Running Win XP, has one ethernet adapter. I'd like to share Internet connection of the Box 1 with Box 2 via cable and have box 1 also sharing the Internet with other wireless devices. I don't want to buy any additional hardware. Is it possible? PS: Sorry if I'm unclear. I merely know nothing about NAT and network administration.

• Why has ESXi 5.0 not used the software RAID configuration on my test server?

  - by kafka

  I've got a test server which was running WS 2008 Enterprise on the bare metal. It was correctly using the software RAID 1 configuration (2x250 GB disks which appeared as one disk), setup on the Dell Poweredge T110 (which meets compatibility requirements) without requiring any extra setup from me. (As an aside I'm fairly sure it's software RAID, as we didn't spec a hardware RAID controller, if that's of any importance in this situation). I am now testing installing ESXi 5.0 on this server to run some VMs. I've successfully installed ESXi, and imported a VM fine, but it's showing 2 x 250 GB disks available as datastores. However they should be appearing as one volume. When I boot the server, there is a RAID configuration screen you can enter, and I'm guessing this is what I'll have to do at some stage, but now need to be very careful because there is one disk which contains data that I want to be mirrored on the other disk. What is the best thing to do in this situation?

• Feeding the kernels entropy source from other machines and/or increasing its maximum size

  - by David Spillett

  We have has a little trouble with a small box that acts as a VPN end-point and mail relay for our network, caused by the available entropy for /dev/random being too low (which causes TLS connection attempts by exim to fail). The machine doesn't do anything else, so the normal feed into the entropy pool (interrupt timings from things like disk access) is not enough. As a quick hack I've set a looping script that reads from /dev/hda at a couple of Mbyte/sec which keeps it topped up. Other than buying a hardware RNG, is there a clean way of piping data for entry from elsewhere, such as a copy of the data our file server uses for its entropy source? I've spotted several tips for using rng-tools to feed it from /dev/urandom on the same machine but that "feels dirty". Also, is it possible to increase the maximum pool size? It currently seems to max out at 3585.

• Can i create a virtual machine on my laptop to be used with another monitor?

  - by Ranhiru

  OK, the scenario is like this... I have my laptop... and I have another user without a unit. He has only a keyboard, mouse and a monitor. Is there anyway that I can make him use my computer by creating a virtual environment which he will access, BUT, without interfering with my work. I use my laptop and view my OS from the laptop monitor. I create a virtual environment (some OS probably XP) and run it. The virtual environment is displayed in the connected monitor and the other user uses it using the extra keyboard/mouse and the monitor but without interfering my screen! Is this possible? Stupid? Futuristic? Need more hardware?

• How to set up my network/bridging using Apple Airport equipment?

  - by John

I want to plug it into an Apple Airport Express and create my wireless my wireless network here. The airport express will do the NAT and DHCP. By my TV there are a few things to be networked (Xbox and Tivo). I have an airport extreme here. I'd like to have the airport extreme join the wireless network and share the connection to the ethernet ports. Can anyone provide some assistance on the best way to configure to do this? Thanks!

• Can I use the voice & SMS features of my GSM SIM through my laptop?

  - by i..

  My laptop (a Lenovo T410s) has an internal GSM modem (device manager calls it a Qualcomm Gobi 2000 HS-USB Modem 9205) that I'm currently using a regular (voice, data, text, etc) 3G SIM in. The data functionality works great through the Lenovo software & Windows 7 but I was wondering if I can use the other features (specifically voice & SMS) through Windows. Is it posisble to use the non-data features of my 3G SIM through my Qualcomm GSM modem? If so, what software is available to this end? If not, where is the restriction? (e.g. hardware, OS, driver, software) Thanks!
