• Apache Server with memcache, varnish and php slow request times

  - by coolestdude1

  My issue is that these servers are taking rather long for request about 2 seconds on average just to serve files. When we had just one server doing everything it was noticeably faster even with the same web app (Drupal 6 and Drupal 7). I want to get this number down to a reasonable level and so I need some help getting to the bottom of why the request times are so slow. This can cause the webapp to hang on post or put and generally leads to a bad user experience on my sites. PS: I am more of a server newbie so this has confounded me for quite some time. The domains: collabornation.net nptrainingworks.com (they run off the same two webservers using vhost configs) The Gear: Two Rackspace 4 Gig servers running CentOS 6.2 Final They have a mounted file system (gluster) that is used to keep files the same on both machines. They are behind a rackspace load balancer running round robin. Mysql is run using php-pdo and php-mysql as such mysql is run on another instance running memcache on that machine with phpMyAdmin located there as well. Apache version number 2.2.15-15.el6.centos.1 (httpd.x86_64) Varnish version number 3.0.2-1.el5 (varnish.x86_64) PHP version number 5.3.14-1.el6.remi (php.x86_64) Configs Linked Below Apache Conf Vhost Conf Varnish Backends Varnish Defaults Varnish Acl PHP INI Again need some help, much appreciated!

• Recovering ZFS pool with errors on import.

  - by Sqeaky

  I have a machine that had some trouble with some bad RAM. After I diagnosed it and removed the offending stick of RAM, The ZFS pool in the machine was trying to access drives by using incorrect device names. I simply exported the pool and re-imported it to correct this. However I am now getting this error. The pool Storage no longer automatically mounts sqeaky@sqeaky-media-server:/$ sudo zpool status no pools available A regular import says its corrupt sqeaky@sqeaky-media-server:/$ sudo zpool import pool: Storage id: 13247750448079582452 state: UNAVAIL status: The pool is formatted using an older on-disk version. action: The pool cannot be imported due to damaged devices or data. config: Storage UNAVAIL insufficient replicas raidz1 UNAVAIL corrupted data 805066522130738790 ONLINE sdd3 ONLINE sda3 ONLINE sdc ONLINE A specific import says the vdev configuration is invalid sqeaky@sqeaky-media-server:/$ sudo zpool import Storage cannot import 'Storage': invalid vdev configuration I should have 4 devices in my ZFS pool: /dev/sda3 /dev/sdd3 /dev/sdc /dev/sdb I have no clue what 805066522130738790 is but I plan on investigating further. I am also trying to figure out how to use zdb to get more information about what the pool thinks is going on. For reference This was setup this way, because at the time this machine/pool was setup it needed certain Linux features and booting from ZFS wasn't yet supported in Linux. The partitions sda1 and sdd1 are in a raid 1 for the operating system and sdd2 and sda2 are in a raid1 for the swap. Any clue on how to recover this ZFS pool?

• Custom PCI bracket with support, for custom PCB?

  - by newbiez

  I am considering to put a custom PCB card that I made, into my computer. It won't go on any PCI connector, it plugs in on a USB connector on the motherboard, via a ribbon cable. I need thou to plug a device to it; which means that either I leave the PCB outside the case, hanging by the ribbon (bad idea), or I could put it in a PCI slot, using a bracket. The issue is that the brackets that I have, do not have tabs, so I have no way to screw the PCB on them. I was hoping to find something that would allow me to put the PCB on it, and then just fit it in the PCI bracket opening, like this: http://www.idotpc.com/TheStore/pc/viewPrd.asp?idproduct=1203&idcategory=0 This one won't fit the bill since the holes are too close apart, compared to the one that I have already on the PCB (and can't make more holes). Do you know if there is a place where they make universal PCI bracket mounting systems for custom PCB? I just need one, so can't even order a custom one (they ask me 120 dollars for one). Thanks in advance!

• Stepmania + KDE4 = sound problem

  I cannot manage to get KDE4 + stepmania working.

Which is pretty bad for an application like this one. I'm quite sure that the problem is in phonon that is blocking the audio device to which StepMania needs to access directly. I think that I can fix this if I run other (lighter) window-manager than KDE4. But that is not a solution occasional linux user. Do I have any chance to get StepMania under KDE4 completely working?

• What games work well on MacBook Pro (i7/GeForce GT 330M) within VMWare Fusion?

  - by webworm

  I have a 15" MacBook Pro (2.66 i7 with 8 GB RAM) with the GeForce GT 330M 512 MB graphics card. I use it primarily for development (Mac/Web/Windows) though I would like to play the occasional game with my son who uses a desktop PC system at home. I prefer to use VMWare Fusion for virtualization rather than BootCamp for a number of reasons. Heat/Fan issues with i7 under BootCamp Prefer to retain virtual machine as single file rather than dedicated partition (easier to move a nd backup) I have heard that Windows support of the GeForce GT 330 in BootCamp is not all that good. So that being said I was wondering what sort of games I would be able to play within the Fusion environment running Windows 7. I have 8 GB RAM and usually dedicate 4 GB to the virtual machine. I don't expect to be able to play the latest FPS games such as BattleField: Bad Company 2 or Call of Duty, rather I am looking at games such a Total War II, Civilizations IV, Supreme Commander, and other RTS type games. I should mention the native screen resolution of my MacBook Pro is 1680x1050, which is what I would be most likely running the VM at (fullscreen). Thank you for any advice.

• SSH does not allow the use of a key with group readable permissions

  - by scjr

  I have a development git server that deploys to a live server when the live branch is pushed to. Every user has their own login and therefore the post-receive hook which does the live deployment is run under their own user. Because I don't want to have to maintain the users public keys as authorized keys on the remote live server I have made up a set of keys that 'belong's to the git system to add to remote live servers (In the post-receive hook I am using $GIT_SSH to set the private key with the -i option). My problem is that because of all the users might want to deploy to live, the git system's private key has to be at least group readable and SSH really doesn't like this. Here's a sample of the error: XXXX@XXXX /srv/git/identity % ssh -i id_rsa XXXXX@XXXXX @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: UNPROTECTED PRIVATE KEY FILE! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ Permissions 0640 for 'id_rsa' are too open. It is required that your private key files are NOT accessible by others. This private key will be ignored. bad permissions: ignore key: id_rsa I've looked around expecting to find something in the way of forcing ssh to just go through with the connection but I've found nothing but people blindly saying that you just shouldn't allow access to anything but a single user.

• need to bring back win 7

  - by user290513

  I like making music and playing games and occasionally do some Photoshop. I had a windows 8 computer but my mouse pointer always got stuck, so to try out something new I installed Ubuntu. here is how I installed it: Went to advanced statup options clicked on "use a device" after plugging in my bootable USB with Ubuntu replaced my windows 8 and installed Ubuntu 14.04 LTS I hope I did it correctly though. So after a few months I could've really find out a good Audio Production (not LMMS, because I use Stagelight) software nor something that could be familiar to the UI of Photoshop. So I decided to bring back Windows, but because of the bad experience of 8 I thought about bringing back win 7 So I used an app named WinUSB to make my bootable USB drive after formatting it to NTFS in GParted But when I go to my grub menu, my USB doesn't show up and my PC being a UEFI device. I don't know how to get to the bios of my device. Can somebody tell how to install Windows 7 completely and deleting Ubuntu or at least give me a link to a tutorial. I have a netbook: it is an Acer Aspire One 725. I'm fine with using commands in terminal and another thing that my laptop doesn't have a CD drive or reader, I can't put a CD inside

• How can I monitor network traffic?

  - by WIndy Weather

  I have a home network with about 10 devices including BluRay player [netflix] and both windows and linux machines. I need to collect network traffic statistics so that if questions come up about how much traffic I'm using I have the answer independent of my ISP. I've looked at DD-WRT, but I see that even buying a new router that will be supported is a problem since I might get the wrong version of the hardware. I have a DIR-655 and a DIR-501 - neither of which is supported. I don't mind buying new hardware, but it looks like a crap-shoot to get one that will work. DD-WRT looks like a bad solution unless someone knows of a place to get a router that is guaranteed to work. Does someone know of an arduino or other SBC solution? I have plenty of NAT routers already, so I just need traffic statistics for external traffic. The network is GBit Ethernet inside and Cable / soon to be DSL outside. The DIR-655 only gives me "packets", not bytes transferred oddly enough. Thanks, ww

• Dead Linux server - need help and options

  - by Choi S.

  All, I have a Dell PE 1950 w/ 2 SATA drives in a software RAID1. OS is CentOS 5.5 (2.6.18.x). Starting this afternoon we received HW errors (something on the bus is bad, E171F) and the machine became unresponsive. We hard booted and it came back up for about 5 hours but then it happened again. I'm trying to figure out our options. Unfortunately we do not have similar hardware but I have a small desktop that I can use. I was contemplating putting one of the drives into the desktop and then starting it up. My goal was to then P2V it using Vmware converter but apparently the free v5.x doesn't support hot cloning/converting on a RAID volume, only the Enterprise 4.x version of Converter does. My questions are: 1.) Is putting a single drive out of a RAID1 pair into another piece of HW is safe? Based on my research and understanding it appears to be but would like confirmation. 2.) Is there any work around to the Vmware Converter not supporting RAID volumes during a hot clone/convert session? 3.) Are there other options I'm overlooking? Thanks in advance for reading and responding. --Choi S.

• Why is my server performance degrading to the point of stopping, periodically?

  - by Pascal Aschwanden

  So, once in a while, I see in firebug that a request takes over 15 or even 60 seconds to respond and sometimes never. Here is what I've ruled out: It's not the CPU, cuz every time I check the Server load its less then 6 for all 3 numbers It's not the memory, because thats fairly low too, less the 50% It's not the I/O anymore, because I've seen the graphs that Joyent sent back to me when I requested them, and they show less then 3MB of I/O (mostly all read). It's not the SQL performance - I've profiled every last SQL command that runs, and they're all (99.9% of them anyway) running in less then 30ms, most run in less then 5ms. Oh and I've been profiling all the script execution times, and even the when the problem occurs, the script always manages to finish in 50ms or less (that's 1 / 20th of a second ). Now, I do run alot of ajax calls. 1 every 2 seconds per user and I have 300 DAU+. But, even if all 300 are playing simultaneously, thats still only 150 calls per second max. The only other thing I can think of is that one of my neighbors is funky. The problem is highly intermittent. 99% of the time it works perfectly and there's excellent performance. but 99%+ is not good enough. Eventually the performance gets so bad I have to restart the server, at which point everything is fine again. I've done this about 4 times now. Any ideas? Note: this is on joyent, vps, intro package 256mb of ram with bursting. here are the mysql dump info: Traffic ø per hour Received 18 MiB 29 MiB Sent 134 MiB 221 MiB Total 151 MiB 251 MiB Connections ø per hour % max. concurrent connections 5 --- --- Failed attempts 0 0.00 0.00% Aborted 0 0.00 0.00% Total 9,418 15.59 k 100.00%

• System randomly freezes yet mouse still moves, SSD out of reallocatable sectors, should I replace it?

  - by user784446

  This problem has lasted for the past 48 hours. The first time it happened, a program I was running stopped responding, so I tried to end it from task manager. The processes at first were listed fine until hovered upon. Eventually, despite the mouse still being able to move, after a few persisting clicks the mouse finally stopped moving. The screen went blank shortly thereafter. The second time it occurred, items on the screen stopped responding - hovering over the taskbar or such wouldn't elicit a response. Sound would still play however. Eventually, the mouse became unresponsive and the system restarted itself. I suspect that it may be a problem of my SSD drive. After looking through some Google search results, I downloaded HDTunePro to determine if there's a problem with the drive. Results returned a problem of reallocated sector count. An error scan also revealed 48 bad sectors. Also, an attempt to backup the contents of the most important areas of the drive returned a few explorer "Error: cannot read source from disk" errors. Should I ditch the drive and use another drive or is there anything that can be done to repair the drive? SSD: OCZ Petrol 64gb CPU: AMD Athlon II X4 640 RAM: Generic 3GB DDR2 Motherboard: Gigabyte MA74GM-S2H OS: Windows 7 Ultimate x64 Thanks!

• Windows 7 Media Center: sometimes no sound on a TV channel

  - by torbengb

  Problem Sometimes, recorded TV shows have no sound. This is of course very annoying because the recorded show is worthless. Also, when switching channels while watching live TV, sometimes a channel has no sound. This is always solved by switching channel again and then back (most often, once will do the trick). Media Center doesn't do this trick by itself when recording of course, so that's the bigger issue - but the cause is certainly the same. Details The computer is running a newly installed Windows 7 and Windows Media Center. It has 2 different tuner-cards installed. Both are installed with signed and up-to-date Win7 drivers and appear OK in Device Manager. Both tuners get the same antenna signal, from a split cable from the wall. The cable delivers analog cable TV (40+ channels) and digital cable TV (4 channels) at the same time. Both tuners have been configured to receive both analog and digital channels. This only happens with analog channels. How can I fix the no-sound problem? Update: I've now spent some time with the computer to try and pinpoint the problem, but I've had little success so far: I flipped through the channels until one didn't have sound, then I disconnected the antenna cable from one of the tuners. It was the right one because then the video also went away. I flipped lots more channels to see if the other card also would come up mute once but I never had a channel without sound. It might still be possible, I don't know. Then I disconnected the "good" tuner and connected the "bad" tuner and again flipped lots of channels but again I never had a channel without sound. It seems to me that the problem is erratic. It happens on any channel, and I haven't ruled out yet that it only happens on one tuner.

• Looking for advice on using dd to backup a dual boot laptop.

  - by AvatarOfChronos

  My questions boils down to this. If I do "dd if=/dev/sda of=usbdrive" can anybody confirm that this will get everything including mbr/partition information/all four partitions and create a drive that I can swap with the failing internal drive without losing anything? If this is done while the computer is running will it still copy everything? At this point I'm afraid to shutdown the computer for fear of it never starting again. Secondly, how tolerant is dd of failing drives? Has anybody used it to recover a half dead drive before that can share any potential pitfalls? Did it get the data ok or is this going to be a hope for the best kind of situation? And lastly, If the usbdrive is larger than the failing internal drive I'll still be able to expand the partitions later so I'm not losing space? this last part seems silly to ask but with my current streak of bad luck I'll end up overwriting some magic bit and forever turning a 640gb hdd into a 500gb hdd. Also if anybody has a better solution to create a complete clone that gets everything I'm all for hearing about it. PostScript: I had been making periodic backups however when whatever miasma that killed the laptop struck it also got the NAS :( Post PostScript: both devices were on a UPS system.

• Using Truecrypt to secure mySQL database, any pitfalls?

  - by Saul

  The objective is to secure my database data from server theft, i.e. the server is at a business office location with normal premises lock and burglar alarm, but because the data is personal healthcare data I want to ensure that if the server was stolen the data would be unavailable as encrypted. I'm exploring installing mySQL on a mounted Truecrypt encrypted volume. It all works fine, and when I power off, or just cruelly pull the plug the encrypted drive disappears. This seems a load easier than encrypting data to the database, and I understand that if there is a security hole in the web app , or a user gets physical access to a plugged in server the data is compromised, but as a sanity check , is there any good reason not to do this? @James I'm thinking in a theft scenario, its not going to be powered down nicely and so is likely to crash any DB transactions running. But then if someone steals the server I'm going to need to rely on my off site backup anyway. @tomjedrz, its kind of all sensitive, individual personal and address details linked to medical referrals/records. Would be as bad in our field as losing credit card data, but means that almost everything in the database would need encryption... so figured better to run the whole DB in an encrypted partition. If encrypt data in the tables there's got to be a key somewhere on the server I'm presuming, which seems more of a risk if the box walks. At the moment the app is configured to drop a dump of data (weekly full and then deltas only hourly using rdiff) into a directory also on the Truecrypt disk. I have an off site box running WS_FTP Pro scheduled to connect by FTPs and synch down the backup, again into a Truecrypt mounted partition.

• What could cause Windows 7 to hang whenever I install something?

  - by Larsenal

  I've had this problem when installing several different programs (iTunes, Adobe Acrobat Reader just to name two). Regardless of what the program is, the install usually gets at least 90% through the process and then just hangs. I don't see anything bad in the event log besides the following (and this didn't occur exactly at the time of install): wuaueng.dll (964) SUS20ClientDataStore: A request to write to the file "C:\Windows\SoftwareDistribution\DataStore\DataStore.edb" at offset 16252928 (0x0000000000f80000) for 32768 (0x00008000) bytes succeeded, but took an abnormally long time (185 seconds) to be serviced by the OS. This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem. I've run check disk and it passed. I've had some problems with BIOS settings in the past with Windows 7, but I'm not sure whether that could be related. Update... I also see this error in the event log: Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. hr = 0x80070005, Access is denied. . This is often caused by incorrect security settings in either the writer or requestor process.

I see "Previous versions" of c:\ which look like they correspond to the time of attempted installation.

• Can Windows Media Player create playlists based on folder structure?

  - by Chaulky

  Over the years I've carefully molded my digital media collection into a series of folders that make it easy for me to find what I'm looking for. I recently discovered the awesomeness that is streaming video from Windows 7 Media Player to the PS3 so I can watch it on the big screen without all the hassle of hooking the computer up to the TV. The problem is, I totally lose my carefully crafted folder structure and all my videos become one giant mess again... not cool! As a temporary solution, I've created a few playlists for my favorites (Dexter Season 4, Dexter Season 5, Breaking Bad Season 1, etc.). This is a HUGE pain in the a$$. So, is there a way to get Windows Media Player (on Windows 7) to maintain some sort of folder structure based on the location of the actual video files? So if I have my videos sorted into folders by show and season, Media Player will pick that up and let me browse it in the same way. As an alternative answer, I'll accept suggestions for a program that can also stream to PS3 and has this "folder organization" feature.

• Does SNI represent a privacy concern for my website visitors?

  - by pagliuca

  Firstly, I'm sorry for my bad English. I'm still learning it. Here it goes: When I host a single website per IP address, I can use "pure" SSL (without SNI), and the key exchange occurs before the user even tells me the hostname and path that he wants to retrieve. After the key exchange, all data can be securely exchanged. That said, if anybody happens to be sniffing the network, no confidential information is leaked* (see footnote). On the other hand, if I host multiple websites per IP address, I will probably use SNI, and therefore my website visitor needs to tell me the target hostname before I can provide him with the right certificate. In this case, someone sniffing his network can track all the website domains he is accessing. Are there any errors in my assumptions? If not, doesn't this represent a privacy concern, assuming the user is also using encrypted DNS? Footnote: I also realize that a sniffer could do a reverse lookup on the IP address and find out which websites were visited, but the hostname travelling in plaintext through the network cables seems to make keyword based domain blocking easier for censorship authorities.

• PAM with KRB5 to Active Directory - How to prevent update of AD password?

  - by Ex Umbris

  I have a working Fedora 9 system that's set up to authenticate users via PAM - krb5 - Active Directory. I'm migrating this to Fedora 14, and everything works, but it's working too well :-) On Fedora 9, if a Linux user updated their password, it did not propagate to their Active Directory account. On Fedora 14, it is changing their A/D password. The problem is I don't want A/D to be updated. Here's my password-auth-ac: auth required pam_env.so auth sufficient pam_unix.so nullok try_first_pass auth requisite pam_succeed_if.so uid >= 500 quiet auth sufficient pam_krb5.so use_first_pass auth required pam_deny.so account required pam_unix.so account sufficient pam_localuser.so account sufficient pam_succeed_if.so uid < 500 quiet account [default=bad success=ok user_unknown=ignore] pam_krb5.so account required pam_permit.so password requisite pam_cracklib.so try_first_pass retry=3 type= password sufficient pam_unix.so sha512 shadow nullok try_first_pass use_authtok password sufficient pam_krb5.so use_authtok password required pam_deny.so session optional pam_keyinit.so revoke session required pam_limits.so -session optional pam_systemd.so session [success=1 default=ignore] pam_succeed_if.so service in crond quiet use_uid session required pam_unix.so session optional pam_krb5.so I tried removing the line password sufficient pam_krb5.so use_authtok But then when attempting to change the Linux password, if they provide their A/D password for the authentication prompt, they get the error: passwd: Authentication token manipulation error What I want to achieve is: Allow authentication with either the A/D or Linux password (the Linux password is a fall-back for certain sysadmin users in case A/D is unavailable for some reason). This is working now. Allow users to change their Linux passwords without affecting their A/D passwords. Is this possible?

• backup an existing linux server to a virtualbox virtual machine

  - by user146526

  I have some servers and VPSs to many companies across the world. I want to back them up locally. I have some backup solutions enabled to remote hosts, but I want to have a local backup on a computer at home. What I am thinking is: 1) Create a virtualbox virtual machine, install the same version linux as the server. 2) Use rsync to backup the server to the local virtualbox machine. (something like rsync -av --delete --progress --exclude '/dev/' --exclude '/proc/' root@server_ip:// / ) 3) Repeat the command every few days update files. 4) In case of a hard disk failure, or any other bad event, reverse the rsync command and get the files back and continue my bussiness. I tried it with 2 openvz VPS, the one was a backup of the other. I also tried to transfer normal linux server host to openvz machine and it worked great. That way looks pretty clean and easy to me, this is the kind of solution I am looking for. However I need to be sure that this will work if I am going to do it. The question is, will that work ok ? Does anyone see any problem with that ? Do you have any other suggestions ? Thanks

• Nagios DNX plugins

  - by danneh3826

  I'm toying with the idea of multiple Nagios instances setup to monitor our infrastructure. I've looked at all the various methods of distributed Nagios checks, and I think DNX comes out the closest. DNX handles failure of worker nodes, that's fine. What happens if the main DNX server fails though? Is there a way to replicate the server too? I'm using AWS EC2 primarily, so I can utilise Elastic Load Balancing for the web UI, but I need to be able to handle the AZ where the monitoring server is to fail over, and essentially for a second to pick up the checking load (active/passive, active/active, so long as it doesn't fail completely) The other thing I'm trying to solve is an issue with routing. What I'd like is to have multiple nodes report a fault before Nagios confirms it as critical. Not the NRPE checks, as they're pretty self explanitory, but things more like check_ping. I often have routing issues out of AWS to certain datacenters, so Nagios can often report bad/no ping/timeout as a critical issue, even though the machine in question is working fine. Would it be possible to have a setup where a worker complains a service check is critical, and have a second worker node (positioned in another datacenter/AZ) also report the service as critical before the Nagios central server issues a critical alert? I realise I might be asking a bit much (how far down the line do you go setting up failover systems before it starts to get ridiculous), however surely someone must have thought of this scenario when developing DNX?

• Pulling application updates from closest server?

  - by Mike Morris

  Setup: 6 Major Sites with Server 2003/2008 DCs doing DHCP/AD Integrated DNS, each on their own subnet. All connect back to datacenter through a 3 mbps WAN ERP server running in the datacenter, accessed by clients at all sites Currently, when we update the software, I manually push a copy of the updated client/config files down to each DC. I have a script that we run on each PC to update the clients. It determines what subnet the PC is on, and pulls the software from that DC. It's messy, but it works. The client has an autoupdate feature, but it'll only pull from the application server (which is housed in the datacenter, over the 3 meg link). It takes forever, since the updates are not "patches" but a full version of the client, even for minor upgrades (bad design). After the most recent patch, you can configure the clients to pull from a different server. Unfortunately, it is the same for all clients. Is there some kind of DNS magic I can use to pull from the local server? For instance, if I tell the clients their update server is ERPUPDATE, can I have their local DNS server return a different IP for ERPUPDATE than the other sites? Example: Client 1 is at site A, client 2 is at site b. They each run the software and a version change is detected. As per the config files, the clients look to ERPUPDATE for their updated client. Client 1 queries DNS for the IP of ERPUPDATE at its current location (site A) DNS at site A returns 192.1.1.5 Client 1 pulls update from 192.1.1.5 Client 2 queries DNS for the IP of ERPUPDATE at its current location (site B) DNS at site B returns 192.1.2.5 Client 2 pulls update from 192.1.2.5 Excuse the poor explanation, I worked 61 hours over the weekend and haven't completely rebounded. I'll be happy to clarify if needed!

• Surround in Windows 7 with Soundmax

  - by Henri

  Hey guys, I have a asus m2n motherboard with a Soundmax 1988 chip on it. I want to have surround sound in windows 7, but i cant get it to work. I tried a lot of different drivers, including the latest beta for Win 7. The problem is that when I configure the speakers and i do a "Test" all speakers work. But whenever I want to play some video or mp3, only the front speakers work. In vista there was this option called "Surround Fill" that would fix this problem, however, I cant seem to find that in windows 7. (The enhancements tab is completely gone for the speakers, other output devices do have that tab). Anybody knows the fix? Edit: I got it now kind of working by using a trial version of SRS AudioSandbox. However, the quality is quite bad since the program tries to create a real 5.1 of stereo sound. I just want to have stereo over 4 speakers instead of fake 5.1 over 4 speakers.

• Computer not finding hard drives on boot -sometimes-

  - by todd.pund

  Computer specs: Mobo: Gigabyte ultradurable 3 - GA-970A-UD3 Processor: First gen I7 3.2GHZ Ram: 8GB Kingston DDR3 1066 Video Card: EVGA NVidia GTX 460 1GB Hard Drive: 500MB 7200rpm x2 (can't remember brand, sorry I'm at work.) Last week my developer preview for Windows 8 ran out so I put my copy of windows 7 back on the computer. The computer at that point started suffering from frequent freezing and crashing. When I rebooted the computer sometimes it wouldn't find the system HD at all. When I looked at the post screen it seemed to show that it wasn't finding either of the HDs. Then yesterday when turning on the computer I just got GRUB as a message (not a GRUB prompt, just GRUB) I haven't had a dual boot of Linux for at least a year. I loaded windows 7 recovery console from the disk and ran: bootrec /fixboot bootrec /fixmbr Which did not help. At that point I just installed Ubuntu 13.04 over the windows 7 install and still received the GRUB post. I went into the BIOS and switched the Hard Drive priorities and then it loaded into Ubuntu fine. For several days everything was just hunky dory until I installed the Ubuntu version of Steam, install Portal and tried to run it. At that point the computer froze and after hard rebooting couldn't find the hard disks again. Then after restarting the system it loaded up fine again and no issues since. (I have not tried to launch portal again). My next thought is to remove the system hard drive and try to use the secondary as the master to see if the primary HD is bad. I'm sorry if this has been confusing, I'll answer any questions I can. Any thoughts?

• umask seems to vary by user

  - by paullb

  I've got a development Ubuntu system for which I have several users: myself (with full sudo) and about 5 other users. (I've set up the system so everything in this respect is still at its default setting) I'm trying to set the system up so that multiple people can collaborate in a single directory by using grouing and I want the default permissions to be 664. However when some users edit files the permissions were 644. After a lot of investigating most users have a umask (checked at the prompt) of 0002 and when they create files they are 664 (as expected) but there are 2 (myself and one other) who have 0022 umask (so the files that come out are 644 and nobody else can write to them). I've looked everywhere but can't figure out why a couple users wind up with a different umask e.g. there is nothing the .bash_profile or anything like that) Any ideas for the source of the discrepancy? /etc/bashrc if [ $UID -gt 199 ] && [ "`id -gn`" = "`id -un`" ]; then umask 002 else umask 022 fi /etc/profile if [ $UID -gt 199 ] && [ "`id -gn`" = "`id -un`" ]; then umask 002 else umask 022 fi EDIT: My (bad) ~/.bashrc # .bashrc # Source global definitions if [ -f /etc/bashrc ]; then . /etc/bashrc fi # User specific aliases and functions export LANG=en_US.utf8 Other user (good) .bashrc # .bashrc # Source global definitions if [ -f /etc/bashrc ]; then . /etc/bashrc fi # User specific aliases and functions

• CD Drive not discovered

  - by user1009073

  I have a self built computer. it uses a P6T Deluxe motherboard, which has both SATA and IDE ports. This was built several years ago, and had an IDE CD/DVD drive. This drive started going bad (would not burn CDs correctly), so I decided to replace it. I had difficultly finding an IDE DVD drive, so I bought a SATA DVD drive. I opened the comnputer, took out the old DVD drive. I left the IDE cable in place, connected to the motherboard, but it is not connected to any drives. I hooked up the new DVD drive, both power and with a SATA data cable (SATA port 3 if I recall). (Sony Optiarc 24x , Newegg URL: http://www.newegg.com/Product/Product.aspx?Item=N82E16827118067 ) When I power on my computer, the drive does NOT show up in Explorer. I can hit the DVD eject button, and the drive will open up, so I know it at least is getting power. I thought, maybe something in the BIOS. When I go to BIOS, boot devices, it shows (1) floppy, (2) my hard drive (3) ATAPI CD Drive. The only other possible BIOS option I could find was uder 'Storage Configuration'. Configure Storage as: My setting is RAID, since I am using two drives in a RAID configuration. Other options were IDE and ACHI. Other than trying to find an IDE DVD drive, is there anything else I can try? The drive does not show up at all in Windows Explorer. I did put in a CD thinking that might help, but nothing happened. Thanks, GS
