• Why are the analoge stereo input and output of my M-Audio 24/96 soundcard not available to me in Ubu

  - by user37968

  I have installed Lucid on an old Mac PowerPC G4 desktop with a M-Audio Audiophile 24/96 soundcard. The only inputs and outputs I can select in the audio preferences are digital ones for the digital input and output. "lspci -v" shows the card as so: 0001:10:13.0 Multimedia audio controller: VIA Technologies Inc. ICE1712 [Envy24] PCI Multi-Channel I/O Controller (rev 02) Subsystem: VIA Technologies Inc.

Alternatively I have seen other people with problems with this device so it may be a bug in the driver but that is another matter. I would like to get the M-Audio card working so I can begin to enjoy my music once again. As a note, I do not currently have any audio equipment capable of sending or receiving audio via the digital inputs and output so I can not check if they are working. The sound preferences show a wide range of digital in and out options with various surround sound options but no analogue ins and outs.

• Wireless 802.11x Disconnects

  - by BillP3rd

  I've looked at (and read) all of the similar questions and none of them get exactly to the issue I'm having at home. I have an 802.11g access point (two, actually, with different SSIDs and on different channels). One is an Airlink AR525W. The other is a Linksys WRT54G v.2. The issue is that at random times, my laptop will lose its wireless connection. This occurs regardless of which access point I'm connected to. When I lose the connection, the affected AP no longer appears in the list of available APs. Also, it doesn't have anything to do with walls or distance. It can happen within 30' and when my laptop is literally within line-of-sight. When it loses the signal, it can take from 10 to 30 minutes to reconnect and it always will without intervention. I've done all the “standard” things to troubleshoot the problem and it has improved. For example, I surveyed other access points in my vicinity and have selected a different channel for each of my APs that no one else nearby is using. Both APs are configured WPA2/AES. I'm down to wondering [Note: This is not a shopping question. I'm not buying a new AP] if the fact that I didn't drop two bills on my APs and instead opted for more modest solutions has anything to do with it? I've oft wondered why anyone would go for the high-end AP when they didn't have to. Also, I am aware of DD-WRT and have chosen not to go there because only one of my APs is supported. Oh, and one final thing. It an HP x64 laptop running Windows 7 Ultimate. The wireless interface is an Atheros AR9285 802.11b/g/n WiFi Adapter. All the latest drivers and service packs have been applied. It did the same thing with my old laptop (a Lenovo) so I don't the problem is in the laptop. It's really annoying when this happens and suggestions of things I haven't thought of or may have overlooked (No, really. As unlikely as it is, I admit that I may have overlooked something :-)) are appreciated.

• Why is my new Phenom II 965 BE not significantly faster than my old Athlon 64 X2 4600+?

  - by Software Monkey

  I recently rebuilt my 5 year old computer. I upgraded all core components, in particular from an Athlon 64 X2 4600+ at 2.4 GHz with DDR2 800 to a Phenom II 965 BE (quad core) at 3.6 GHz with DDR3 1333 (actually 1600, but testing consistently detected memory errors at 1600). The motherboard is also much newer and better. The HDD's (x3), DVD writer and card reader are the same. The BIOS memory config is auto-everything except the base timing which I overrode to 1T instead of 2T. The BIOS CPU multiplier is slightly over-clocked to 3.6 GHz from the stock 3.4 GHz. I noticed compiling Java is slower than I expected. As it happens I have some (single-threaded) Java pattern-matching code which is CPU and memory bound and for which I have performance numbers recorded on a number of hardware platforms, including my old system. So I did a test run on the new equipment and was stunned to find that the numbers are only slightly better than my old system, about 25%. The data set it is operating on is a 148,975 character array, which should easily fit in caches, but in any event the new CPU has larger caches all around. The system was, of course, otherwise idle for the test and the test run is a timed 10 seconds to eliminate scheduling anomalies. A long while ago, when I upgraded only memory from DD2 667 to DDR2 800 there was no change in performance of this test, which subjectively supports that the test cycle does not need to (significantly) access main memory, but yes it is creating and garbage collecting a large number of objects in the process of this test (low millions of matches are found for the pattern set). I am about 99.999% certain the code hasn't changed since I last ran it on 2009-03-17 - but I can't easily retest the old hardware, because it is currently in pieces on my work-bench waiting to be built into a new computer for my kids. Note that Windows (XP) reports a CPU speed of 795 MHz unless I have some thing running. With stuff running it seems to jump all over the place each time I use ALT-Pause to display the system properties, everywhere from 795 MHz to 3.4 Ghz. So why might my shiny new hardware under-performing so badly? EDIT: The old memory was Mushkin DDR2 800 with timings set for auto which should have been 5-5-5-12. The new memory is Corsair DDR3 1600, running at 1333 with timings also auto which are 9-9-9-21. In both cases they are a paired set of dual channel DIMMs. I was waiting to ensure my system was stable before tweaking with memory timings.

• ruby on rails gitorious setup on ubuntu

  - by dogmatic69

  Ive been trying to install gitorious for a while now which required ruby and rails etc. Ive finally got rails pages serving but cant finish the installation of gitorious because the gem version is too new. the error logs say please run 'rake ultrasphinx:configure' and that gives rake ultrasphinx:configure (in /var/www/apps/gitorious) rake aborted! uninitialized constant ActiveSupport::Dependencies::Mutex /var/www/apps/gitorious/Rakefile:10:in `require' (See full trace by running task with --trace) From searching google this is beacuse of the wrong gem verison. Cant find a way to down grade it. apparently sudo gem update --system 1.4.2 should do the trick but ubuntu 10.10 does not like this. ERROR: While executing gem ... (RuntimeError) gem update --system is disabled on Debian, because it will overwrite the content of the rubygems Debian package, and might break your Debian system in subtle ways. The Debian-supported way to update rubygems is through apt-get, using Debian official repositories. If you really know what you are doing, you can still update rubygems by setting the REALLY_GEM_UPDATE_SYSTEM environment variable, but please remember that this is completely unsupported by Debian. So i added export REALLY_GEM_UPDATE_SYSTEM=1 to .bashrc and reloaded it with . ~/.bashrc and still the same. ive tried various forms of setting this environmental variable with no luck. Ive also been told on #gitorious irc channel to add the file config/initializers/rubygems.rb with the line require "thread" to it. This has done nothing. EDIT: Just found another way which was rvm install rubygems 1.4.2 and it gave: Removing old Rubygems files... Installing rubygems dedicated to ruby-1.8.7-p334...

• IE and Google Chrome timeout on an IIS6 hosted SSL page that Firefox handles well

  - by Thomas

  Ok, here's the scenario: Up until a few weeks ago, none of us noticed anything wrong with the corporate website. People were using it without complaint. Then, a client complained that a specific page on the site was timing out for him, and only when he committed a POST action on a form filled with data. I checked it out, and it timed out for me, too. But, it only timed out in Google Chrome and IE, not in Firefox. Additionally, the same page, on the same server, but served from a different domain name (one not under the protection of SSL, either) does not time out under any browser. To clarify: https://www.mysite.com/changes.php times out on POST, but the same with http works fine. That distinction (SSL vs. Non-SSL) seems to be important, as nothing else has changed. Our certificate is valid, and Firefox detects no errors thrown by the page. I've looked at the Request and Response headers from the page, and they all follow the correct formats. Then, after wandering through the site, I noticed a few other things. Both IE and Chrome will frequently time out on any page that is PHP-based. They never time out on static images or html files. I've looked at the site from a variety of different servers, my home and work workstations, and my netbook. Because of that, I've discounted a viral infection, as I highly doubt a virus is going to hit every one of the machines to which I have access in exactly the same manner. My setup is: Server: Win2k3, II6, PHP 5.2.9-1. Clients: IE7, IE8, Chrome (regular and dev channel): Frequent timeouts on PHP pages. Firefox 2, Firefox 3: No timeouts. Firebug shows no errors or even lengthy periods serving the pages. I've spent 2 days searching for any tech knowledge that I can find, and my search parameters are all too general. Everyone has problems loading SSL pages in IE and Chrome for a wide variety of reasons. The infrequent nature of the timeouts and the fact that there are no errors being reported anywhere is starting to drive me insane. Does anyone have any insight on a problem like this?

• PCI-DSS compliance for business with only swipe terminals [migrated]

  - by rowatt

  I support the IT infrastructure for a small retail business which is now required to undergo a PCI-DSS assessment. The payment service and terminal provider (Streamline) has asked that we use Trustwave to do the PCI-DSS certification. The problem I face is that if I answer all questions and follow Trustwave's requirements to the letter, we will have to invest significantly in networking equipment to segment LANs and /or do internal vulnerability scanning, while at the same time Streamline assures me that the terminals we have (Verifone VX670-B and MagIC3 X-8) are secure, don't store any credit card information and are PCI-DSS compliant so by implication we don't need to take any action to ensure their network security. I'm looking for any suggestions as to how we can most easily meet the networking requirements for PCI-DSS. Some background on our current network setup: single wired LAN, also with WiFi turned on (though if this creates any PCI-DSS complexities we can turn it off). single Netgear ADSL router. This is the only firewall we have in place, and the firewall is out the box configuration (i.e. no DMZ, SNMP etc). Passwords have been changed though :-) a few windows PCs and 2 windows based tills, none of which ever see any credit card information at all. two swipe terminals. Until a few months ago (before we were told we had to be PCI-DSS certified) these terminals did auth/capture over the phone. Streamline suggested we moved to their IP Broadband service, which instead uses an SSL encrypted channel over the internet to do auth/capture, so we now use that service. We don't do any ecommerce or receive payments over the internet. All transactions are either cardholder present, or MOTO with details given over phone and typed direct into terminal. We're based in the UK. As I currently understand it we have three options in order to get PCI-DSS certification. segment our network so the POS terminals are isolated from all PCs, and set up internal vulnerability scanning on that network. don't segment the network, and have to do more internal scanning and have more onerous management of PCs than I think we need (for example, though the tills are Windows based, they are fully managed so I have no control over software update policies, anti virus etc). All PCs have anti virus (MSE) and windows updates automatically applied, but we don't have any centralised go back to auth/capture over phone lines. I can't imagine we are the first merchant to be in this situation. I'm looking for any recommendations a simple, cost effective way to be PCI-DSS compliant - either by doing 1 or 2 above with (hopefully) simple and inexpensive equipment/software, or any other ways if there's a better way to do this. Or... should we just go back to the digital stone age and do auth/capture over the phone, which means we don't need to do anything on our network to be PCI-DSS certified?

• Why do some games randomly turn my screen a random solid color?

  - by Emlena.PhD

  When playing some games my computer will randomly have an error that I cannot fix without turning it off and back on again. The screen changes to one solid color, which varies (off the top of my head I can remember seeing solid green, magenta, etc..) and the sound blares a single tone. The sound sometimes briefly restores and I can still hear the game sounds and even hear and still be heard by people in my Mumble channel, but the screen doesn't right itself so I'm still blind. What's more is this happens in some games but not in others. While the game is actually running, not while I'm still in the menu. However, it does happen if I'm afk or idle but the game world is still rendering. Games where the error occurs: League of Legends World of Warcraft Trine The Sims 2 Dungeon Defenders Safe games: games where it has never occurred: Tribes: Ascend Star Wars: the Old Republic Battlefield 3 So relatively older games cause the problem while newer games do not? I cannot predict when it will happen, it just seems random. However, if it happens and I try playing the same game further after restart it does appear to occur more frequently after the first time. But if I switch to a safe game it doesn't continue happening. Both of my RAM sticks appear fine, flipped position or either one on their own and games still run, computer still boots. I would think over-heating, but then why not all games? ALso, sometimes it happens immediately after I start playing, within seconds of the 3D world booting up. I'm looking to upgrade very soon so I want to figure out what component or software is fubar and replace/repair it. Any suggestions or recommendations of tools would be helpful. Below is some system information. Dxdiag does not detect any problems.

• Concatenation of a 2 second silence audio with a normal audio not working

• OS X server large scale storage and backup

  - by user135217

  I really hope this question doesn't come across as trolling or asking for buying advice. It's not intended. I've just started working for a small ad agency (40 employees). I actually quit being a system administrator a few years ago (too stressful!), but the company we're currently outsourcing our IT stuff to is doing such a bad job that I've felt compelled to get involved and do what I can to improve things. At the moment, all the company's data is stored on an 8TB external firewire drive attached to a Mac Mini running OS X Server 10.6, which provides filesharing (using AFP) for the whole company. There is a single backup drive, which is actually a caddy containing two 3TB hard drives arranged in RAID 0 (arrggghhhh!), which someone brings in as and when and copies over all the data using Carbon Copy Cloner. That's the entirety of the infrastructure, and the whole backup and restore strategy. I've been having sleepless nights. I've just started augmenting the backup process with FreeBSD, ZFS, sparse bundles and snapshot sends to get everything offsite. I think this is a workable behind the scenes solution, but for people's day to day use I'm struggling. Given the quantity and importance of the data, I think we should really be looking towards enterprise level storage solutions, high availability and so on, but the whole company is all Mac all the time, and I cannot find equipment that will do what we need. No more Xserve; no rack storage; no large scale storage at all apart from that Pegasus R6 that doesn't seem all that great; the Mac Pro has fibre channel, but it's not a real server and it's ludicrously expensive; Xsan looks like it's on the way out; things like heartbeatd and failoverd have apparently been removed from Lion Server; the new Mac Mini only has thunderbolt which severely limits our choices; the list goes on and on. I'm really, really not trying to troll here. I love Macs, but I just genuinely don't know where I'm supposed to look for server stuff. I have considered Linux or FreeBSD and netatalk for serving files with all the server-y goodness those OSes bring, but some the things I've read make me wonder if it's really the way to go. Also, in my own (admittedly quite cursory) experiments with it, I've struggled to get decent transfer speeds. I guess there's also the possibility of switching everyone off AFP and making them use SMB or NFS, but I understand that this can cause big problems with resource forks and file locks. I figure there must be plenty of all Mac companies out there. If you're the sysadmin at one, what do you use? Any suggestions very gratefully received.

• BIND DNS server (Windows) - Unable to access my local domain from other computers on LAN

  - by Ricardo Saraiva

  I have a BIND DNS server running on my Windows 7 development machine and I'm serving pages with WAMPSERVER. My ideia is to develop some tools (in PHP) for my intranet at work and I want them to be accessible via LAN in this format: http://tools.mycompany.com I've already placed BIND and I can access http://tools.mycompany.com on the machine that holds BIND server, but I cannot access it from other LAN computers. I've done the following on my router: defined static IP's for all LAN computers set Port Forwarding to my server (remember: it serves DNS and Web pages) set DNS server configuration to point to my LAN server On LAN computers, I went to Local Area Network properties and also changed the DNS server IP in order to point to my local DNS server. If it helps, here is my named.conf file: options { directory "c:\windows\SysWOW64\dns\etc"; forwarders {127.0.0.1; 8.8.8.8; 8.8.4.4;}; pid-file "run\named.pid"; allow-transfer { none; }; recursion no; }; logging{ channel my_log{ file "log\named.log" versions 3 size 2m; severity info; print-time yes; print-severity yes; print-category yes; }; category default{ my_log; }; }; zone "mycompany.com" IN { type master; file "zones\db.mycompany.com.txt"; allow-transfer { none; }; }; key "rndc-key" { algorithm hmac-md5; secret "qfApxn0NxXiaacFHpI86Rg=="; }; controls { inet 127.0.0.1 port 953 allow { 127.0.0.1; } keys { "rndc-key"; }; }; ...and a single zone I've defined - file db.mycompany.com.txt: $TTL 6h @ IN SOA tools.mycompany.com. hostmaster.mycompany.com. ( 2014042601 10800 3600 604800 86400 ) @ NS tools.mycompany.com. tools IN A 192.168.1.4 www IN A 192.168.1.4 On the file above 192.168.1.4 is the IP of the local machine inside my LAN. Can someone help me here? I need my web pages to be accessible from other computers inside my LAN using my custom domain name. I've tried on other computers and they can access my server via http://192.168.1.4/, but no able when using http://tools.mycompany.com . Please, consider the following: I'm completely new to BIND I have basic knowledge in Apache configuration Thanks a lot for your help.

• How should I use my new SSD drive?

  - by jasondavis

  I just built a new PC the other day. Specs... Processor: Intel i7-930 quad core CPU CPU Cooler: COOLER MASTER Hyper 212 Motherboard: AsRock X58 Extreme 3 RAM/Memory: 6gb G-Skill tripple channel DDR3 memory (3 sticks of 2gb planning to get another kit to make it 12gb total soon) Operating System Hard drive: Intel X25-M 80GB Mainstream SATA2 Solid State Drive Video Cards: 2 XFX ATI Redeon HD 4650 cards to run 3-4 monitors Case: Lian Li PC-B10 Midtower case Power Supply: Antec TruePower New TP-750 Blue 750W Operating System Windows 7 Pro 64bit Not sure if the specs are helpful at all but I posted them just in case. So I got everything put together and running great so far but I need some advice/ideas/help/tips. I got the SSD drive in hopes of using it strictly for my windows 7 install along with all my other programs I install. I am then going to get another drive or 2 just for data (video,music,photos, etc). So my plan is to just install the new data drives and then in windows 7 I will change my "My documents" "My Music" "My Video" "MY Photos" library's to be located on the data drives instead of the OS SSD drive. I would ultimately like to install all my programs with my windows install on the SSD drive and then create an IMAGE of the drive and then 6 months down the road if things are sluggish I can just wipe the drive and restore my IMAGE with all my programs and settings in tact still. So here are some questions now. 1) How can I verify that TRIM is working on my new SSD? 2) Is there anything above that I missed that I should be doing? I think I once read that there is a page file or some sort of file that windows changes a lot and that it should be moved off f an SSD an onto my data drives. DOes anyone know what I might of heard? If you do can you explain the pros and cons of doing such a thing as well as how to possibly? 3) Any tips or advice to get the best performance from all this, I built a pretty nice system and I just want to make it stay that way as long as I can.

• What Sort of Server Setup Am I Likely to Need? - School A/V streaming

  - by DeathMagus

  My prior experience with servers has generally been limited to home file-sharing servers, low-traffic web-servers, and the like. This leaves me with the technical knowledge of how to set up a system, but little experience in terms of scaling said system. My current project, however, has me as the technical lead in setting up a school for online audio and video streaming. The difficulty I'm running into is that I don't quite have the experience to guess what they'll need, and they don't have the experience to tell me - so I've tried to ask as many pertinent questions about what they want to do with their server, and here's what I found out: About 1000 simultaneous users, and hoping to expand (possibly significantly) Both video and audio streaming, at obviously the highest quality possible Support for both live and playlist-based streaming. Probably only one channel, but as it's an educational opportunity, I imagine letting them have a few more wouldn't hurt. No word on whether they're locked into Windows or whether Linux is acceptable. Approximate budget - $7000. It may actually be about $2k less than this, because of a mishap with another technology firm (they ordered a $7000 DV tape deck for some reason, and now the company wants them to pay a 30% restocking fee). The tentative decisions I've already made: I'm planning on using Icecast 2 for my streaming server, fed by VLC Shoutcast encoding. Since the school already has a DMZ set up, I plan on placing the Icecast server in there, and feeding it through their intranet from a simple workstation computer in their studios. This system isn't in any way mission critical - it's an education tool (they're a media magnet school), so I figure redundancy is not worthwhile to them from a cost:benefit perspective. What I don't know is this: How powerful of a server will I need? What is likely to be my major throttle - bandwidth? How can I mitigate that? Will I need anything special for the encoding workstation other than professional video and audio capture cards and a copy of VLC? Are there any other considerations that I'm simply missing? Thanks a lot for any help - if there's more information you need, let me know and I'll tell you all I can.

• DNS Issue Windows 2003 AD-The server holding the PDC role is down

  - by Dave M

  Our network of Windows 2003 and Windows 2008 servers suddenly hasDNS issues. There are 7 DCs. Two at our main office and one each at branch sites (one branch has two a 2008R2 and WIN2K3) Only two are WIN2008R2 Running DCDIAG on the WIN2K3 at main site (DC1) reports no issues. Running at any branch site reports two issues All other test pass. The server DC1 can be PINGed by name from any site Starting test: frsevent There are warning or error events within the last 24 hours after the SYSVOL has been shared. Failing SYSVOL replication problems may cause Group Policy problems. Starting test: FsmoCheck Warning: DcGetDcName(PDC_REQUIRED) call failed, error 1355 A Primary Domain Controller could not be located. The server holding the PDC role is down. Netdom.exe /query DC reports the expected servers. netdom query fsmo This reports the server at the main office holds the following roles: * Schema owner Domain role owner PDC role RID pool manager Infrastructure owner In the DNS management snap-in, DC1 appears as DNS server but does not appear in _msdcs-dc-_sites-Default-First-Site-Name-_TCP There is no _ldap or –kerberos record pointing to DC1 Same issue msdcs-dc-_sites- -_TCP Again there is no _ldap or –kerberos record pointing to DC1 Under Domain DNS Zones there is no entry for the server. This is the case for any _tcp folder in the DNS. The server DC1 appears correctly as a name server in the Reverse Lookup Zone. There is a Host(A) record for DC1 but in the Forward Lookup Zone there is no (same as parent folder) Host(A) for the DC1 server but such an entry exists for the other DCs at branch sites and the other DC at the main office.

• Computer suddenly dies; screen displays weird flickering lines, then restarts

  - by Imray

  I've been having this terrible problem for a little while and just managed to get a picture of 'dead screen' for the first time and I am posting it to seek help. Randomly, at irregular intervals (typically once a week), while working on something (it's been different things every time) my computer will just suddenly go dead - the screen turns to exactly the picture below (the lines flicker a little bit), it hangs there for a few seconds and then restarts. Obviously this is extremely frustrating and I want to try to stop it. I've searched numerous postings with similar keywords but nothing exactly the same as mine. Does anyone have any idea what might be the cause of this? I would post all my system settings and installed programs but the list is long and I don't know how much relevance each item would be. If you'd like to know something specific, please comment and I'll let you know whatever you need.

• What are the most likely bottlenecks determining the performance of CamStudio screen recording?

  - by Steve314

  When doing screen recording, I can get a frame rate of maybe 15 frames per second for the full screen on my 1080p monitor using the XVID codec. I can increase the speed a bit by recording a region, changing screen modes, and tweaking other settings, but I'm curious what hardware upgrades might give me the biggest bang for my buck. My PC is budget, but modern... Athlon 2 X4 645 (3.1GHz, quad core, limited cache) processor. 4GB single channel DDR3 1066 RAM. ASRock motherboard with NVidia GeForce 7025/nForce 630a Chipset. ATI Radeon HD 5450 graphics card - 512MB on board, not configured to steal system RAM. I dual-boot Windows XP and Windows 7. For the moment, XP is my bigger performance concern as it's still my getting-things-done O/S as opposed to my browser-host O/S. My goal is to make a few programming-related tutorials. For a lot of that I don't need screen recording - I can make up some slides, record audio with the PC switched off, yada yada. When I do need screen recording, I'll mostly be recording Notepad++, Visual Studio or a command prompt. Occasionally, I may be recording some kind of graphics or diagram program and using my pre-Bamboo cheap Wacom tablet - I have the CS2 versions of Photoshop and Illustrator, but I'd much more likely be using Microsoft Paint. Basically, what I'll be recording won't be making huge demands on the machine - but recording a fair number of pixels (720p preferred) will be useful. What's particularly wierd - not so long ago I still had a five-year-old Pentium 4 based PC. And (with the same 1080p monitor) it could record at not far from the same frame rate. So clearly the performance issues are more subtle than just throw-money-at-it. My first guess would be that the main bottleneck is the bandwidth for transferring data to/from the graphics card. Is that likely to be correct? In support of that, see this [Radeon HD 5450 review][1] - the memory bandwidth is only 12.8 GB/s. If you can't get data out of graphics memory quickly, you can't transfer it back to the system memory quickly. Apparently, that's slower than some top-end cards in 2002.

• Some Memory Slots Not Working on MSI FM2-A85XA-G65 Motherboard

  - by Mike Ciaraldi

  Short version of question: Does anyone have an MSI FM2-A85XA-G65 motherboard, who can confirm that all four memory slots work? Long version: Several months ago I bought an MSI FM2-A85XA-G65 motherboard at Newegg. At that point I installed an AMD A8-5500 processor and two sticks of Corsair Vengeance 8 GB DDR3-1866 memory, and put it into my file server. I installed the RAM in slots 1 and 3, as directed in the manual, to enable dual-channel memory access. It seemed to work fine, so I bought a second identical mobo (which arrived dead, but was quickly replaced by Newegg) and set of RAM, installed an A10-5800K, and put that into my production Linux machine. Again, it seemed to work well. Eventually I happened to notice that on the server only 8 GB of RAM appeared in the BIOS. I tried each of the slots and memory modules individually and in various combinations. I even swapped processors with the production machine. The result was that putting memory in slots 1 and 2 worked (showing a total of 16 GB), but any memory in slots 3 or 4 was not recognized. However, all four memory slots in the production machine worked, and I confirmed this with both processors. I contacted MSI and arranged to ship the defective mobo back to them for replacement under warranty. I did not want my file server to be down in the interim, and I had another machine I wanted to upgrade, so I bought a third identical mobo to use. That one had the same problem -- only memory slots 1 and 2 worked. I tested it thoroughly with multiple processors and memory sticks. I sent the defective mobo back to MSI and they sent me a new one. This has the same memory slot problem. So I sent it back. The replacement arrived the other day and shows the same problem. I contacted MSI yet again and they said that nobody else has reported memory slot problems on this board and it must be my processor. So my score so far is, out of six boards of this model, I have: One where all four slots work. One which was dead on arrival. Four where only memory slots 1 and 2 work. Before I tear my other machines apart and start swapping processors again I thought I would ask if anyone else has this exact model motherboard and could confirm that all four memory slots either do or do not work. According to MSI you should be able to just plug a single memory module into any of the slots and it will work (and it does on the one mobo I have which works correctly). If you have not yet used all four slots, this is a good time to test them so you know if you can expand your memory in the future. Thanks in advance to anyone who can help.

• Caching issue with Centos forwarding DNS server

  - by Paddington

  I installed a Forwarding DNS server on Centos 5.10 and it is resolving addresses e.g google.com. When I stopped named (service named stop) and tried to dig (dig @localhost A google.com) there was a failure to resolve the address. I checked and see the caching daemon nscd is running. Does this mean the server is not caching at all? How can I get it to cache? named.conf options { // Those options should be used carefully because they disable port // randomization // query-source port 53; // query-source-v6 port 53; // Put files that named is allowed to write in the data/ directory: listen-on port 53 {127.0.0.1; 10.0.0.4;}; directory "/var/named"; // the default dump-file "/var/named/chroot/var/named/data/cache_dump.db"; statistics-file "/var/named/chroot/var/named/data/named_stats.txt"; memstatistics-file "/var/named/chroot/var/named/data/named_mem_stats.txt"; // allow-query {localhost; 192.168.0.0/24; 10.0.0.0/8;}; recursion yes; //allow-query { localhost; 10.0.0.0/8;}; allow-query { localhost; any; }; allow-query-cache { localhost; any; }; forward only; forwarders {8.8.8.8; 8.8.4.4;}; dnssec-enable yes; // dnssec-lookaside auto; /* Path to ISC DLV key */ // bindkeys-file "/etc/named.iscdlv.key"; // managed-keys-directory "/var/named/dynamic"; }; logging { channel default_debug { file "data/named.run"; severity dynamic; }; }; **

• Slow WLAN file transfer between server and tablet

  - by user266985

  My file server is running Ubuntu 12.04 and I'm sharing files from it over samba. It is connected via gigabit ethernet. My desktop, running Windows 8.1, is also connected via gigabit ethernet. I can transfer files between the two and completely saturate that gigabit pipe. However, I just got a Surface Pro 2, and I'm trying to stream HD movies from my server to the device over WiFi. For some reason, I can't break much past 1.5MB/s transferring files over the network. I've tried streaming through XBMC and a standard file copy; no difference. To add the confusion, if I connect to my guest network and then use my VPN server (installed on the router) to access the file server, I get around 3.2MB/s. I've been running diagnostics to determine the root and I think I've found it but I have no idea what is causing it or how to fix it.

• Computer randomly reboots during "intensive activity".

  - by Reznor

  My friend has been playing games on his new build for some time now. However, lately, his computer will randomly reboot out of nowhere, so far only happening in game, and presumably only to happen in game as it happens nowhere else. This can happen in game during play or even in the options. Note, it isn't a crash or blue screen. It's just a normal reboot. This started today, I believe, and has only occured in two games: Dead Space and Stalker: Shadow of Chernobyl. He has played a handful of games before these, for about a week or so, without this problem. We theorized on two possibilities: Maybe something is overheating? Maybe the power supply is inadequate? These two were quickly dismissed, as all his components were operating at normal temperatures when he got back to his desktop from the reboot, and we all know these parts don't exactly cool down quickly, especially if they get hot enough to trigger a reboot. Besides, I know at-least my motherboard reports processor overheating at start-up, and requests I press f1 to continue into boot. The PSU one was dismissed too. He has an 850w power supply on a rig that was estimated to take only 720 some watts, that's with some overcompensating to be safe. He opened up his case to make sure nothing was seated wrong or in the way. All was fine, but he did notice a sticker on his video card. It had a giant barcode on it and some numbers. Now, I'm used to seeing these stickers, they're the warranty stickers, right, and removal voids the warranty? Yeah, well, we find it odd because this sticker is slapped right over the circuits of the video card, not on a block or anything. Is this normal? Should he remove it? Right now, I am concerned with the memory. Could that be at fault? Here are his specs: Windows 7 Home Premium, 64-Bit Intel i7 950 EVGA GeForce 570 GTX 4 GB DDR3 PC10666 dual-channel Corsair RAM Corsair 850w PSU Gigabyte GA-X58A-UD3R Western Digital 1 TB WD1001FALS

• Java Port Socket Programming Error

  - by atrus-darkstone

  Hi- I have been working on a java client-server program using port sockets. The goal of this program is for the client to take a screenshot of the machine it is running on, break the RGB info of this image down into integers and arrays, then send this info over to the server, where it is reconstructed into a new image file. However, when I run the program I am experiencing the following two bugs: The first number recieved by the server, no matter what its value is according to the client, is always 49. The client only sends(or the server only receives?) the first value, then the program hangs forever. Any ideas as to why this is happening, and what I can do to fix it? The code for both client and server is below. Thanks!
