• X-FI optical output not being recognized.

  - by Luciano

  Hello there! I have an issue and I don't know what to do! I have a SoundBlaster X-FI Xtreme Gamer, which has a spdif mini-optical output. I have it connected to a home theater, via a toslink cable and an adapter to fit in the mini plug. It used to work perfectly, but now it doesn't anymore. There is light travelling through the cable, but the HT doesn't pick up the signal. The sound card of the motherboard also has an optical output (regular, not mini) and it works ok, so the cable and the HT are fine, I think. What else should I try? Thanks, Luciano. PS: I only enabled the onboard card for testing, but usually it's disabled to avoid any kind of conflicts. PPS: I'm using Windows 7 64bit with latest drivers of everything, but like I said. It used to work.

• How to force a resolution in linux?

  - by hi

  I have a HP LP3065 that requires a dual link dvi cable to go up to 2560x1600 resolution. However, I do not have that cable, but I want to use 1920x1200 resolution. However, my nVidia Display Settings (also system display settings) will only go up to 1280x1024, which looks horribly pixelated on the 30". How do I force the 1920x1200 resolution? I tried adding the mode into my xorg.conf file, but it still would not take it. I know my vid card can do 1920x1200 since it works on the 24" monitor with the same dvi cable. Here are my specs: Fedora 12 Nvidia Quadro NVS 420 Intel Xenon E5530 cpu 6gig memory Thanks

• Mac OS X: pushing all traffic through a VMWare VM [closed]

  - by bj99

  I want to set up an Astaro (Sophos) UTM in a Virtual Machine. The Setup should be at the end the following: Cable Modem (one IP adress) | [Ethernet] Sophos UTM (running as VM [VMWare Fusion 5] on the MacMini) | [WIFI] Airport Express v2 (for sharing Local Network to wireless and wired clients) 1)| [WIFI] 2)| [Ethernet over Thunderbolt Ethernet Adapter]* Clients MacMini (Local File Server) *To have the Mini also protected behind the UTM So the setup process for the UTM works fine, but then the problems start: I just have one external IP (from my cable modem provider)== So if I put the VM in briged mode my Internet connection drops, because the MacMini also has its IP adress. If I put the VM to NAT mode the Mini itself is not protected by the UTM So: is there a way to hide the en0 interface(Ethernet) and the en1 interface (Wifi) from the MacMini, so that they not even appear in System Preferences Network section but are available to the VM? That way the Mini must connect to the en2 interface (Thunderbolt adapter) to make any Internet/LAN connection and I just use the given single IP from the Cable Modem. Thaks for any suggestions...

• 3.5mm headphone jack -> Component video?

  - by Isaac Waller

  Hello, I have a strange cord that has a male 3.5mm headphone jack on one side, and some component video and audio ouputs on the other. When I plug the headphone side into my computer, and the other side into my TV, I get audio across the cable, but no video. How can I send some video over the headphone jack in OS X? I know you can, because this cable is actually for a Beyblade toy and it somehow transferred video over this cable. Thanks, Isaac I think I found some more information (from Wikipedia:) "A four conductor version (of a 3.5mm headphone jack) is becoming a de facto standard output connector for compact camcorders, providing stereo sound plus a video signal." So how can I do this on Mac?

• Exchange 2010 remove Arbitration mailbox and mailbox store db

  - by JNM

  I have a problem with Exchange 2010 which is a nightmare for me. The problem is, that in Exchange management console i have several store databases in database management tab. only one is mounted, because i am using it. the second one is mounted, but it was used on other server before (now that server is dead). that database mounted status is UNKNOWN. The file of that database does not exist, but it still shows there. I can't remove it from management console, because it has mailboxes. i removed all mailboxes and disabled two arbitrary mailboxes. i can't delete it because i still have one arbitrary mailbox left. i can't move it, because it requires connection to dead server. i can't disable it, because i get error that it is the last one in organization. Can somebody help me? Solved it by using this command: Get-Mailbox -Arbitration -Database db1 | Remove-Mailbox -Arbitration -RemoveLastArbitrationMailboxAllowed Now i have another problem. Exchange management console shows public folder from different server which is dead now. That folder was copied here, but it is not needed anymore. Public folder file has been deleted, and records from ADSI edit has been removed too. But i can't remove that folder from management console. i get an error Exchange isn't able to check for public folder replicas for "My Public Folder Database". Anybody can help me with that?

• Do all the network cards use the same frequency to send signals to wire?

  - by smwikipedia

  I am comparing my cable TV wire to my network wire. In a TV cable wire, different frequencies are used by different TV channels. And since a certain channel use a fixed frequency, I think the only left way to represent different signal is with the carrier wave's amplitude. But what about the network wire? For all the network cards with the same type, do they also use different frequencies to send signals just like TV cable? I vaguely remember that they use frequency adjustment to represent signals. So the frequency should not be a fixed one. So how did all the network cards that sharing the same medium differentiate their own signal from others?

• Laptop charger disconnects and reconnects, charger or battery broken?

  - by Rob

  I've got an Acer Aspire One netbook (AOA-150) and there's obviously something wrong with it. The charging port gets VERY HOT and the charger seems to disconnect and reconnect quickly sometimes. This only happens when the netbook is running, and it doesn't seem to care what it's doing other than being on. The battery has an extremely short life (< 30minutes, sometimes) and I almost exclusively run it on the power cable (which needs the battery plugged in. Having it just plugged into the wall won't start up). Does this sound like a problem with the power cable or the battery? The plug for the cable and the port get so hot that if I held them for longer than a few seconds, I'm sure I'd get burnt. EDIT Just got "Popular Question" on this and it WAS the power jack. The ground on it came loose from the board. A bit of solder on it and everything is working great again.

• Connect to development server via switch?

  - by letseatfood

  I apologize upfront if this isn't appropriate for superuser. I asked it on serverfault and was told it was too general for that site. I have a laptop with Vista and it receives it's internet connection wireless. I have an old desktop with Ubuntu 10.04 Server Edition installed and it is setup as a development server with Apache, MySQL, and PHP. This works well, with the server having a static IP address. The server is connected to the router via an Ethernet cable. Is it possible to disconnect the cable that is currently connecting the server and the router, then connect the server and workstation to a switch, so that I am still able to connect to the server via web browser from the workstation? I am trying to eliminate the long ethernet cable connecting the server to the router in the other room. I already have a switch, that is why I asked specifically about it. Thanks and I will be more than happy to clarify!

• Using PowerShell, in Active Direcotry, how would I change all the DNS A records that have a given IP to a new IP?

  - by djsumdog

  We've been moving data centers and I have a lot of old records that were not correctly but in DNS as CNAME records, but A records that have a direct IP (e.g. 192.168.100.n) and they're all moving to a new subnet (10.19.100.n). I just need to write a powershell script to change all those records. I found this site: http://www.indented.co.uk/index.php/2008/12/30/administering-microsoft-dns-in-powershell/ and from it I made this simple script: $dnsServer = "meldc2" $scope = New-Object Management.ManagementScope("\\$dnsServer\root\MicrosoftDNS") $path = New-Object Management.ManagementPath("MicrosoftDNS_Zone") $options = New-Object Management.ObjectGetOptions($Null,[System.TimeSpan]::MaxValue, $True) $ZoneClass= New-Object Management.ManagementClass($scope,$path,$options) $Zones = Get-WMIObject -Computer $dnsServer -Namespace "root\MicrosoftDNS" -Class "MicrosoftDNS_Zone" $Zones | Get-Member foreach($Z in $Zones) { $Z | Select-Object Name,DsIntegrated,ZoneType,Reverse,Data } but that only gets me a listing of root zones. I don't understand how to iterate over all the entries in each of the zones. Also, all the examples I've seen involve adding new zones, but there aren't any examples I can find on modifying existing A records.

• Sharing internet connection from Windows XP using wi-fi router

  - by Darius

  Hi, I have an network configuration like: Ethernet cable from ISP connected to Windows XP machine, configured with static IP 192.168.0.3 Another ethernet connection from 2nd Windows XP machine's network adapter to a Wi-Fi router (D-Link Airport G+) XP set to "Share internet connection", the 2nd adapter configured as static to 192.169.0.1 D-Link Airport Wi-Fi router also configured as "static connection", it's IP set to 192.169.0.2, default gateway set to 192.169.0.1. Network mask everywhere is 24. Laptop computer connected with the router with static IP 192.169.0.3 The problems are: XP machine sees the router (it's able to ping it and access it via the web admin tool) The router somehow cannot PING the XP machine (using the tool provided by the web-based admin tool) The laptop computer cannot ping anything and cannot be pinged The router is only accessible when the ethernet cable is connected with a router's 1-4 LAN port, when I connect it via "WAN" port (which I believe is the proper one) it's not visible from the XP machine If you have similar experience with configuring a network like this I would really appreciate your help. I cannot use the Wi-Fi router with the ISP cable itself.

• In search of a good audio player for Ubuntu 9.10

  - by Joe Casadonte

  If this should be marked Community Wiki, please let me know. I'm switching from XP to Ubuntu, and I have been very disappointed with the selection of media players available. I'm primarily interested in an audio player, but integrated video and library management is OK, too. My criteria: Must be able to play audio CDs (I'm shocked how many apps this does away with, right away) Must be able to play MP3 & WAV; OGG, SHN, FLAC are all bonuses Repeat and Shuffle modes are a must FreeDB / GraceNote through a proxy is a must (if it can read a PAC file, that would be awesome) It needs to be really small, e.g. skinnable or an applet Ability to execute a playlist is a plus Gapless MP3 playback a plus I'm running Gnome, but I'm not totally adverse to a KDE app. Command-line only is also a viable option. Some that I've tried: RhythmBox - probably the best of the lot that I've tried; I don't like its mini mode (doesn't show the song being played) and I can't figure out how to get it to hit FreeDB/GraceNote through a proxy Songbird - can't play CDs, playlist management is atrocious Banshee Jajuk Maybe a couple of more. Thanks! UPDATE I tried out VLC, Amarok and Songbord (again). VLC I eventually got to work (I had some kind of bad configuration). It seemed way more involved than I was looking for out of a music player, and in general more geared to video than audio. I couldn't fathom its library management, which I think it has; maybe it doesn't, and that's why I couldn't figure it out. Amaork looked very promising but the library management was not to my liking, and the way it handled a playlist with both MP3 and WAV is inexplicable at best. I did like some aspects of the UI, but not enough to keep it. Songbird is very finicky, but I like the library management. Sort of. It kept telling me my Watch folder was invalid, even thought it clearly was accessible. Playlist management is bizarre, and the message that it was deleting source files whenever I deleted a playlist had me too worried to keep using it. Had it been able to play CDs, maybe I would have persevered. Audacious, while a bit odd at times, does seem to do what I want. If it had a library manager, I wouldn't have bothered trying any of the others. Thanks for the help, everyone!

• external HDD with SATA & USB interface?

  - by Greg

  Anyone know of an external HDD that would have (in addition to USB) a SATA (eSATA) port/cable? i.e. Brand/Model. Preferably one of the name brands so I have a better change of finding it here or locally if possible. Background - In one location I want to use it is I would like to increase the performance by cabling it directly to the PC SATA port, HOWEVER I don't want to have to open up the PC to do this each time. I was thinking of running a SATA cable out through the PC case so I just plug it directly into the external HDD in question. Perhaps it should be also externally powered too so I don't need to run a power cable out from the PC power supply.

• Is there a performance difference between Cat5 and Cat6 keystone blocks?

  - by Scott Anderson

  I'm going to be wiring my home for ethernet soon, and I've already decided that I want to use Cat6 cable to do it (faster speeds, better performance, etc). During the installation, I'd like to add wall-plates to certain rooms in my house, and the keystone blocks look like the best option for me. My question is: I've seen different keystone blocks on many cabling websites, some say Cat5e and some say Cat6. The Cat6 ones are slightly more expensive. Is there any noticeable performance gain from using a Cat6 keystone? To me, it just seems like the keystone really wouldn't matter, since it's basically like putting an RJ-45 end on a cable. Can I buy the cheaper Cat5e keystone blocks and still have the performance that Cat6 cable will give me? Thanks!

• Block users from Social networking websites while firewall is down

  - by SuperFurryToad

  We currently have a SonicWall firewall, which does a pretty good job a blocking Social networking websites like Facebook and Bebo. The problem we are having is that sometimes we need to temporarily disable our firewall blocklist so we can update our company's page on Facebook for example. Whenever we do this, have see an avalanche of users logging on to their Facebook pages during work time. So what we need a way to block access while the firewall is down. For the sake of argument, we have two groups of users - "management" and "standard users". "standard users" would have no access to Facebook, but "management" users would have access. Perhaps something like a host file redirect for non-management users. This could probably be enforced via group policy that would call a bat file to copy down the host file, depending if the user was management or not. I'm keen to hear any suggestions for what the best practice would be for this in a Windows/AD environment. Yes, I know what we're doing here is trying to solve a HR problem using IT. But this is the way management wants it and we have a lot of semi-autonomous branch offices that we don't have a lot of day to day contact with, so an automated way of enforcing this would be the most preferable method.

• Connect by Wifi to Sql Server from another computer

  - by Bronzato

  I try to connect by Wifi to Sql Server with Sql Server Management Studio from another computer but it failed. I have a computer with Windows Seven & Sql Server 2008 (lets say the server computer). Next to it, I have a fresh installed computer with Windows Seven & Sql Server Management Studio (let's say the client computer). What I do on the server computer: configure firewall by enabling port 1433 enabled network protocols (TCP/IP) inside Sql Server Configuration Manager checked "Allow remote connections to this server" on server properties in Sql Server Management. started Sql Server Browser restarted services (Sql Server Browser is stopped but I think it is not neccessary, isn't it?) Next, I successfully tested a ping on the port 1433 from my client computer with a tool named tcping (ex: tcping 192.168.1.4 1433). But I still cannot connect from my client computer to Sql Server on my other computer. Ok, something new on this problem: until now, I successfully connected to my "server computer" with Management Studio. What I do is typing the computer name in the server name field in the connection window of Management Studio. My previous (failed) attempt was to type the computer name followed by the instance of sql server (ex: COMPUTER_NAME\SQL2008). I don't know why I only have to type the computer name... Nevermind. Now my new challenge is to succeed connecting my VB6 application to this remote database located on my "computer server". I have a connection string for this but it failed to connect. Here is my connection string: "Provider=SQLOLEDB.1;Password=mypassword;User ID=sa;Initial Catalog=TPB;Data Source=THIERRY-HP\SQL2008" Any idea what's wrong? Thanks

• Windows 7 unload driver/disconnect usb before restart

  - by brux

  In xp, my Tascam US 122 usb audio interface works fine. On my windows 7 computer the device works, however when i restart/shutdown it hangs at the "shutting down" screen forever. If the usb cable is removed prior to initiating restart/shutdown then everything goes fine, the computer restarts as normal. This is a known problem, running any other driver in compatibility mode doesnt fix the problem. Is there a method I can use to unload the device/drivers so that I dont have to reach round physically and disconnect the cable. Somebody suggested a spdt switch on the cable itself, but I am looking for a simpler method. Surely I can automate the unloading of the device through a script or such? Any ideas are greatly welcomed thanks

• Does a bad Internet connection increase bandwidth usage?

  - by Synetech

  My (Rogers) cable connection has been pretty bad recently (channels 3 and 10 are particularly fuzzy—it’s analog, not digital cable). Not surprisingly, this has caused my cable modem to drop out and have to reestablish a connection a couple of times since it started. The poor connection of course means higher corruption (not necessarily dropped per se) which causes the TCP/IP stack to have to retransmit packets more often. Reduction of bandwidth throughput aside, I got to wondering if it increases the actual bandwidth usage. That is, if there is a high error rate on the line causing packets to have to be retransmitted: Does this increase a bandwidth monitoring program’s numbers? Does the ISP count the retransmitted packets toward the monthly cap? Based on what I remember from my university networking courses and common sense, I have a feeling that the answer to both questions is yes, but I cannot reliably measure the first, and have no authoritative answer for the second. I’m wondering if maybe the retransmitted packets are acknowledged as being duplicates and thus not counted somewhere along the line.

• Intermittent USB 3.0 access - How do I troubleshoot?

  - by Billy ONeal

  I've got a WD Passport hard disk with "superspeed" USB 3.0 support. When I use my USB 3.0 flash drive (this is a Lenovo X220 laptop), USB 3.0 consistently works. But when I use the passport drive, almost without fail the connection drops to USB 2.0. Touching the cable seems to immediately trigger the problem, but it seems to happen on its own though. I've got another cable on order right now... but is it likely the cable's the issue here? Is there anything else I can check?

• Bridging two connections in windows 7

  - by Serban Razvan

  I have recently bought an Samsung UE32ES5500 and I want to connect it to the internet. Not wanting to buy an expensive Samsung wireless adapter for the TV, I've decided to use an ethernet cable. Because the Internet cable passes through underground to the bedroom and the TV is located in the living room, i decided to put a router in the bedroom, and receive it's signal in the living room using a windows 7 laptop. Afterwards I connected the laptop to the TV through an ethernet cable, and bridged the two connections in Network Connections in Control Panel on the laptop. The TV successfully finds the laptop (and the router I think) but still cannot connect to the internet. Does anyone knows a solution to this problem? (the connections must be bridged because I want to have only one network in the house)

• How to fix unstable RJ45 jacks? [closed]

  - by BeemerGuy

  This is a little project I'm doing at home. I wanted to wire two rooms together (basically, the router is one room, and the switch is in the second room). So I ran a CAT5 between the two rooms, and wired an RJ45 jack in each room. I then hooked up the two jacks with two CAT5 cable to run it through the cable tester, and all 8 wires seem good. Now, when I connect the switch and the router, the connection is unstable -- I ping the router and it barely holds on for two pings before it disconnects, and stays in that unstable state. Just to make sure the router and the switch are ok, I connected them with long wire between the two rooms and the connection is absolutely stable, and pings continuously. What could be the cause for the unstable connection? Especially that it pings a few times, so there IS a connection. But why is it unstable? And how come the cable tester says it's ok, but it's unstable?

• Ubuntu 9.10 freezes when HDMI port is connected

  - by Felipe Hummel

  Hi, I have a Sony Vaio FW350 with a HDMI output. I'm trying to use it under Ubuntu 9.10 with a LG LCD monitor 21,5'. I've tried two approaches: Boot the laptop with the HDMI cable connected and monitor turned on. Result: LCD Monitor keeps turned on but the whole screen is black and Ubuntu do not seem to be initializing. Boot Ubuntu until the end. I then connect the HDMI cable into the Laptop. The mouse and the whole system freezes. In both cases the only way to turn off the laptop is holding the power button. I've looked around the internet for similar problems, but only found workarounds for the same problem with VGA input, not HDMI. I also tried to use metacity before connecting the cable, but still got the same result. Any hints?

• Network router and switch configuration

  - by gilly3

  Can I put a switch before my router in my home network? Here is a diagram of how I want to set up my network: ________________________________ ________________________________________ | | | | | Cable Access Panel | | Home Office | | _____________ ________ | | _____________ | | | | | | | | | | _________ | | | Cable Modem |--->| Switch |-------------->| Router |____| | | | |_____________| |________| | | |_____________| | Printer | | |______________________/____\____| | / | \ |_________| | ___/_ _\___ | _____/ ____|____ \_____ | | | | | | | | | | | | | | PC1 | | PC2 | | | PC3 | | Ext. HD | | PC4 | | |_____| |_____| | |_____| |_________| |_____| | |________________________________________| The reason I want to do this is because my router is also my wireless access point. My cable modem is located in the far corner of my home where my phone/tv/network access panel is. I'd rather keep the wireless access point in a more central location, but I'm not sure if DHCP will continue to work properly with that configuration. Edit: I'd like to continue to be able to share files and access my networked drive and printer from each computer in the house.

• Upgrading HP DL185 G5 8LFF, is using a Dell J1520 4-Drop SATA Adapter possible?

  - by jpreed00

  The HP DL185 G5 8LFF model supports 8 3.5" drives and 1 optical drive. However, instead of the optical drive, I'd like to have 2x 2.5" drives instead. The problem is that the PSU has no more SATA power cables (even though the motherboard has 4 additional SATA data ports). The PSU does have a free 10-pin connector and it looks like the J1520 cable from Dell would fit the bill. Link to cable description Does anyone have any experience using these cables? Are they safe? Any other ideas for adding the disks to the server if I don't use the cable? Thanks!
