  • Can't access WordPress blog after host changed IP address of server

    - by John
    My host changed servers and all websites now have a new IP address. I have the same domain name and I assume the host runs the same nameservers, though my host and domain name provider are different. Notes: I never entered a Name or description under General/Settings for my blog. I left them both blank. That is when I could log into it. The wp-config file, has localhost entered rather than a specific IP. Again this has always been the case and my host never advised otherwise. I can get into cPanel by simply putting the newly advised IP in front of /Cpanel. However, I can not reach the admin panel of my WordPress blog (version 2.8.2). I had been loggin into it via http://xx.xx.xxx.xx/~example/blog/wp-login.php. My host suggested to simply insert the new IP in place of the old one. I still get the error message: 404 Not Found The server can not find the requested page: Apache/2.0.63 (Unix) mod_ssl/2.0.63 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 PHP/5.2.12 Server at 74.50.108.14 Port 80 I followed some tips on a question on Stack Overflow of a similar nature. I have logged into phpMyAdmin and found the wp-options table and searched for SELECT * FROM `wp_options` WHERE `option_name` IN ('siteurl', 'home') Only option ID 39 came up and the results are: Home has optionvalue http://example.org siteurl has optionvalue http://example.org/blog Both of which appear correct. Is there any part of the MySQL tables where I can change an actual IP address? Or is there something else you can advise?

  • Netgear router is not resolving hostnames

    - by Thomas Clayson
    Not sure what the problem is, but I am used to being able to access other clients on my LAN via their hostname. We got a new router from plusnet (Netgear WNR1000v3) and now this has stopped working. For instance, if I were to run a web server from one computer with the hostname TomPC usually I could go into a browser and type http://TomPC and I would get the web server front page. I can access it by using the LAN ip of the machine. e.g. http://192.168.1.1 works fine. I thought it would be a simple option in the admin panel of the router - possibly I had to turn on DNS/DCHP or something. But I can't see anything, and my searches on the internet seem to turn up ridiculous solutions involving setting up a dedicated DNS server on my LAN. This is just a small home network - really I just want to be able to access my Raspberry PI on the network without having to work out the IP address every time. (I know I could just set a static IP address for it, but using its hostname would be much easier). DCHP is enabled in the LAN settings part, although RIP is disabled (I don't know what the latter is) I don't know if this has anything to do with it? Many thanks!

  • How to remove NTFS system files from a previous Vista installation

    - by Boldewyn
    I'm trying to shrink my system partition under Win Vista. It's all fine, except that in front of the last 300MB of the volume sits a single file, that cannot be moved by defrag or other means from its position. It's called C:\$Extend\$UsnJrnl:$J, and my assumtion is, that it is left from a previous installation of Vista, when I re-set up the system. Now, googling for this kind of files brings interesting results, but no solution to my problem: Files left on the disk can become ownerless in a new setup of Windows and inaccessible (even for administrators). To be able to access them again, I found the tip to use takeown to re-assign them to the Admin group (or anyone else). Works like a charm for normal files, but not for the C:\$Extend stuff. The C:\$Extend folder is a system folder of the NTFS file system, where the journal is stored (especially in a file called $UsnJrnl:$Data, whose name is surprisingly close to mine). You can delete the journal with fsutil usn /delete C:, however, this doesn't work from within the booted system (as I found out trying). Also, I'm not quite sure of the side effects. You can't move the NTFS own files with standard defrag tools. The same holds, by the way, for not accessible files. Every bit of knowledge out there is targeted to either not accessible files or the $Extend NTFS stuff, but noone addresses my problem involving both, an inaccessible system file. Question: How can I remove this file, or at least how can I move it on the disk?

  • "Ethernet" doesn't have a valid IP configuration

    - by Xuzuno
    I'm using an ethernet cord to connect to my internet and it has been working well until Thursday morning when I turned on my laptop (Windows 8) to see a yellow triangle sign in the bottom right hand corner, in front of the ethernet connected symbol. Since then I haven't been able been able to access the internet from my computer. When I hover over it, it says that it is an "Unidentified network" and there is "No internet access". I've run the Windows 8 troubleshooting and it says that the problem found was ""Ethernet" doesn't have a valid IP configuration", but I'm unsure how to fix it. I'm thinking that the problem is to do with my computer rather than my network, because I've tried another laptop (Windows 7) through the same ethernet cable and connection and the internet works fine on the other laptop. I've tried so many fixes that I've found online, with none of them actually working. Yesterday I even tried a full system reset, where I re-installed Windows 8, re-partitioned and wiped everything off the hard drive, but it still appears have the exact same problem. Today I also purchased and tried a new ethernet cable which didn't work, so I then purchased a USB to Ethernet adapter, to make sure that it wasn't my ethernet port on my laptop that was faulty. That didn't work either, and the same problem still remains. I feel like I've tried everything, so can someone please help me?

  • New build won't boot: some fans turning, no beep or video

    - by Dave
    When my new system is powered up, the case fan and power supply fans turn fine. The CPU fan twitches, but never gets going. Although I've heard that with AMDs and Gigabyte motherboards that is not necessary a problem. Hard drive is spinning. However, there is absolutely no indication that anything else is happening. The motherboard, as far as I can tell, does not have an internal speaker, but I harvested one from another machine and plugged it in and still no beeps at all. The monitor screen stays black, on both the integrated VGA and DVI. This is a brand new build, and has never successfully booted. My parts are: AMD Athlon II X2 245 Regor 2.9GHz Socket AM3 65W Dual-Core Processor Model ADX245OCGQBOX - includes CPU cooler) GIGABYTE GA-MA785GPMT-UD2H AM3 AMD 785G HDMI Micro ATX AMD Motherboard - Retail G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL8D-4GBRM - Retail CORSAIR CMPSU-400CX 400W ATX12V V2.2 80 PLUS Certified Compatible with Core i7 Power Supply - Retail SAMSUNG Spinpoint F3 HD502HJ 500GB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive COOLER MASTER Elite 341 RC-341C-KKN1-GP Black Steel MicroATX Mid Tower Computer Case - Retail I also have a DVD burner, but it acts the same whether that is plugged in or not. I'm using the on board video. What I've tried so far: I've switched power supplies, with no difference. I've tried different monitors (of which all are working on other machines) with no difference. I have tried putting it one memory module at a time, with no difference. I have tried the absolute minimum I can think of (power supply into motherboard, power button ONLY plugged into front panel, CPU fan plugged in), with no difference. I appreciate any ideas anyone might have. Do I need to RMA the motherboard? This is my first build, so there might be something obvious. I was very careful in assembly with static; I'm confident nothing was zapped during assembly.

  • Exchange 2003 automatically converts text/plain emails to text/html for IMAP retrieval

    - by wfaulk
    When accessing an Exchange 2003 server via IMAP, emails that were sent as text/plain (and ones that had no MIME encoding specified at all) get automatically converted to multipart/alternative with the original text/plain body and a text/html body. This is … stupid. It doesn't even bother to specify a monospaced font. The new MIME part starts like this: Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2//EN"> <HTML> <HEAD> <META HTTP-EQUIV=3D"Content-Type" CONTENT=3D"text/html; = charset=3Diso-8859-1"> <META NAME=3D"Generator" CONTENT=3D"MS Exchange Server version = 6.5.7654.12"> <TITLE>{{subject}}</TITLE> </HEAD> <BODY> <!-- Converted from text/plain format --> <BR> <P><FONT SIZE=3D2>{{body}} (All the "3D" stuff is quoted-printable encoding for an equals sign; there's nothing wrong on that front, surprisingly.) How can I make this stop?

  • How can I use HAproxy with SSL and get X-Forwarded-For headers AND tell PHP that SSL is in use?

    - by Josh
    I have the following setup: (internet) ---> [ pfSense Box ] /-> [ Apache / PHP server ] [running HAproxy] --+--> [ Apache / PHP server ] +--> [ Apache / PHP server ] \-> [ Apache / PHP server ] For HTTP requests this works great, requests are distributed to my Apache servers just fine. For SSL requests, I had HAproxy distributing the requests using TCP load balancing, and it worked however since HAproxy didn't act as a proxy, it didn't add the X-Forwarded-For HTTP header, and the Apache / PHP servers didn't know the client's real IP address. So, I added stunnel in front of HAproxy, reading that stunnel could add the X-Forwarded-For HTTP header. However, the package which I could install into pfSense does not add this header... also, this apparently kills my ability to use KeepAlive requests, which I would really like to keep. But the biggest issue which killed that idea was that stunnel converted the HTTPS requests into plain HTTP requests, so PHP didn't know that SSL was enabled and tried to redirect to the SSL site. How can I use HAproxy to load balance across a number of SSL servers, allowing those servers to both know the client's IP address and know that SSL is in use? And if possible, how can I do it on my pfSense server? Or should I drop all this and just use nginx?

  • Autounmounting USB keys with FAT filesystem on Linux (RHEL5)

    - by niXar
    For security reasons, I have two workstations i front of me, and I can only transfer data between them through a USB key. As you can imagine, it can get quickly tiresome, but the most annoying is having to unmount the things before removing them. Not umounting them results in missing files most of the time, even if I remove them a while after having last written to them. Now, since they're only used for transferring smallish files, and each are basically written once and read once, I don't need the fancy pansy caching infrastructure that makes clean unmounting a necessary step. And since the data is always a copy of something I have at hand, I don't care if the filesystem croaks from time to time. But anyway the system doesn't need to force that on me, it could simply make sure everything is committed with a second, and works synchronously. Then when I remove the key, nothing is lost. Is there a way to do this? I would appreciate any other tips on handling this situation. Edit: it appears the situation has changed between RHEL5 and Fedora up to F11 on one hand, and F12 on the other. The latter use DeviceKit-disk, and I haven't quite figured out how to do this. The method provided below in gconf does not work anymore.

  • Mac mini simple customized, Mac mini server or other?

    - by microspino
    I'm in front of a big IT choice for my little office and I need some advice. We have 5 users, 1 super user, 1 HP500 DesignJet Plotter, other 4 laser printers, 1 HP Fax/Print/Scan/Copy machine. All the clients are XP Sp3 boxes. We would like to: centralize and share 90Gb of files using a Dropbox (this way we will have LAN sync of local working directories + internet backup + access our files wherever we are). centralize our plotter, printers and fax machine backup all the workstations share outlook calendar and tasks run 24x7 saving some energy Of course this setup It's just the first step to a more serious and creative network management of our office, so we are open to new ideas. The budget vary from 400€ to 900€, we are not tech gurus but at least one of us is a power user close to become a geek. I've read some articles on macminicolo about a mac mini either normal or with snow leopard server. I heard about Windows Home Server too on the lifehacker website but I'm in a sort of analysis - paralysis can You help me?

  • how to diagnose a hard system seizure? Dell+Ubuntu

    - by rob
    I've got Ubuntu 9.10 on a Dell Vostro 420 desktop, a little over a year old, which I use for plain vanilla work stuff (email, web, terminal, text editor). Every now and then, at totally random times, it completely freezes on me. Hard. Mouse and keyboard stop working, cursor stops blinking, clock stops moving. All I can do is hold down the power button on the front of the box to shut it off. Sometimes it happens after several months of continuous uptime; sometimes it happens a few minutes after a reboot, while all I've done is open a terminal to look at log files, or maybe firefox to do a google search. Each time, there is nothing at all in /var/log/messages at the time of the crash. This makes it seem like a hardware problem, and indeed a few months ago I opened the box and wiggled everything and the problem went away for a while. But now it's back. I went in and checked everything, took out each RAM card and reseated. No luck. I ran all the system diagnostics (the long version) and everything passed with flying colors. Something is messed up in this box, but without any useful logs or failed tests, how in the world am I going to find it? And of course, Dell's not gonna help me cause I went and replaced Windows with Ubuntu. What steps would you take next to track down this problem?

  • Seperate external and intranet portals using the same functions .htaccess

    - by jezzipin
    We are currently struggling with setting up rules for a .htaccess file for a website built upon our company product. The product is built using PLSQL and procedures can be accessed using URLs. We use this functionality to present different options to our users. These options can be injected into HTML pages using replacement tags. So, the tag [user_menu] is always replaced with: /wd_portal_cand.menu?p_web_site_id={variable1}&p_candidate_id={variable2} for external sites and /intranet/wd_portal_cand.menu?p_web_site_id={variable1}&p_candidate_id={variable2} for internal sites. The issue we are having is twofold. We need to write our .htaccess rules so that the user can access the functionality whether they are internal or external. So, the links should work as follows: http://www.example.com/wd_portal_cand.menu?p_web_site_id={variable1}&p_candidate_id={variable2} or http://www.example.com/internal/wd_portal_cand.menu?p_web_site_id={variable1}&p_candidate_id={variable2} This is the other problem. As you can see for the internal link above, the procedure needs to be prefixed with internal instead or intranet. We cannot change this in our standard tags as this will affect other sites so we need to achieve this also using htaccess. Could anyone assist with this issue? I apologise if this is brief or confusing but it's something i've never done before and have been given the task of doing. I apologise for the lack of code that will be posted above however I am a front end developer and have been left to make these changes having no prior experience of .htaccess to please bare with me.

  • Help trying to figure out why IIS7 is crashing / locking up / denying connections

    - by Pure.Krome
    Hi folks, I've got a pretty busy website that is running on a single web front end machine, on W2K8 + IIS7. Every now and then - eg. maybe monday at 3am or something, then a few days later .. some early morning time .. then nothing for 2 weeks ... etc - the website fails to respond to any client connections. ie. no one can connect to the website. I can remote desktop to the machine, etc no probs. I restart the app pool (the website is running in intergrated mode), still nothing. I try and get a crash dump of the process (it's around 600 mb maybe even more) ... that fails after about a min of trying (and i have plenty of HD space). The only way to fix this issue, is to manually stop the www service and then start it again. The stopping takes a while (a minute?) while starting is nearly instant. I'm at a loss to figure out what part of my code is causing this. At first, I thought it might be a stack overflow because of some error that might be going to the error page, which in turn errors .. rinse repeat boom. But i've had a look at the error page and it feels ok. So, I'm hoping someone might be able to help and say how I can correctly get a proper dump of the IIS process so i can then do some more autopsy on it. I would email Tess Ferrandez (the goddess of crash debuging) but I thought I'd try here before I spam her. Can anyone have any suggestions to how I can figure out how to start to debug this issue?

  • How to Deploy an ASP.NET Web API- and Browser-based Application to a Production Environment [closed]

    - by lmttag
    Possible Duplicate: How to Deploy an ASP.NET Web API- and Browser-based Application to a Production Environment We have an ASP.NET Web API server that serves up a SQL Server data driven website. The API uses JSON to transfer data from SQL Server to the front end. We need to move it to an internal production environment (nothing will be exposed on the public Internet) and we’re having problems - or just not understanding what needs to be done. There are two domains: The corporate domain - where all users login normally. The process domain - contains the database the Web API needs to access. The IT staff wants to put a DMZ between the two domains to house the IIS app and shield the users on the corporate domain from having access into the process domain directly. The ideal configuration is: corp domain (end users) <–> firewall (open port 80) <–> DMZ (web server running IIS) <–> firewall (open port 80 or 1433????) <–> process domain (IIS for Web API and SQL Server) We don’t really understand how to deploy our browser/Web API application in this scenario. Do we need to break up our application so that all the client code is on the IIS server in the DMZ, while the Web API gets installed on the server in the process domain? Does the entire app (client code and Web API) stay together on the IIS server in the DMZ, which then somehow accesses the SQL Server instance to get data? From the IIS server and app in the DMZ, would you simply access the Web API on the server in the process domain by going to http://server/appname/api/getitmes? In the second firewall between the DMZ and the process domain, would you have to open port 1433 or just port 80 since the Web API is a HTTP endpoint? Or, is there some better way of deployment (i.e., how ASP.NET Web API single page applications written all in HTML5 and JavaScript supposed to be deployed to production environments?)? NB: The servers are Win2k8 R2, SQL Server 2k8 R2, and IIS 7.5.

  • How can I keep SSH's know_hosts up to date (semi-securely)?

    - by Chas. Owens
    Just to get this out in front so I am not told not to do this: The machines in question are all on a local network with little to no internet access (they aren't even well connected to the corporate network) Everyone who has the ability to setup a man-in-the-middle attack already has root on the machine The machines are reinstalled as part of QA procedures, so having new host keys is important (we need to see how the other machines react); I am only trying to make my machine nicer to use. I do a lot of reinstalls on machines which changes their host keys. This necessitates going into ~/.ssh/known_hosts on my machine and blowing away to old key and adding the new key. This is a massive pain in the tuckus, so I have started considering ways to automate this. I don't want to just blindly accept any host key, so patching OpenSSH to ignore host keys is out. I have considered creating a wrapper around the ssh command the will detect the error coming back from ssh and present me with a prompt to delete the old key or quit. I have also considered creating a daemon that would fetch the latest host key from a machine on a whitelist (there are about twenty machines that are being constantly reinstalled) and replace the old host key in known_hosts. How would you automate this process?

  • How do I repartition an SDHC card in Windows?

    - by Peter Mortensen
    How do I repartition an SDHC card (4 GB or more)? Do I need third-part tools or Linux (a live CD solution would be OK)? In Windows' Disk Management the option Delete Partition is dimmed out: I can reformat the card as FAT32, copy files to and from the card and even change the file system to NTFS using the command line command CONVERT, but not repartition it. The article How to Partition an SD Card in Windows XP talks about using "a Windows enabler program" which sound rather dubious to me. I have tried to change from “Optimize for quick removal” to “Optimize for performance”. The option to format as NTFS appeared, but the Delete Partition option is still dimmed out. Platform: Windows XP 64-bit SD card reader: USB 2.0 device, LogiLink® CR0005C Cardreader 3,5' USB 2.0 intern 54-in-1 mit USB Front Kingston 16 GB SDHC card, speed class 4. (It could be formatted as FAT32 and successfully used in a 4 GB ReadyBoost setup (Windows 7).) I have also tried on different versions of Windows and with different cards with the same result: Kingston 4 GB SDHC card, speed class 4 (the one shown in the screenshot) Transcend 2 GB (not marked as SDHC, but SD) Windows 7 32-bit (albeit with a somewhat an older card reader) and Windows XP 32-bit on an EliteBook 8730w

  • Force request to miss cache but still store the response

    - by Tom Marthenal
    I have a slow web app that I've placed Varnish in front of. All of the pages are static (they don't vary for a different user), but they need to be updated every 5 minutes so they contain recent data. I have a simple script (wget --mirror) that crawls the entire website every 15 minutes. Each crawl takes about 5 minutes. The point of the crawl is to update every page in the Varnish cache so that a user never has to wait for the page to generate (since all pages have been generated recently thanks to the spider). The timeline looks like this: 00:00:00: Cache flushed 00:00:00: Spider starts crawling to update cache with new pages 00:05:00: Spider finishes crawling, all pages are updated until 1:15 A request that comes in between 0:00:00 and 0:05:00 might hit a page that hasn't been updated yet, and will be forced to wait a few seconds for a response. This isn't acceptable. What I'd like to do is, perhaps using some VCL magic, always foward requests from the spider to the backend, but still store the response in the cache. This way, a user will never have to wait for a page to generate since there is no 5-minute window in which parts of the cache are empty (except perhaps at server startup). How can I do this?

  • Redirecting a single request to another pages, ignoring www subdomain

    - by Petter Brodin
    I have a site running on IIS 7.5 that does an automatic redirect from 'http://mysite.com/whatever.aspx' to 'http://www.mysite.com/whatever.aspx' On the site, there is a lot of traffic to an old URL that I want to redirect to the front page, index.aspx: 'http://mysite.com/foo/bar/index.cgi%something=asdf&somethingelse=qwerty' The problem is that no matter what I try, I can only get the redirect to work with the www subdomain. If I use the URL without www, I just end up at 'http://www.mysite.com/404.aspx' Any ideas? Thanks in advance for all help! Edit3: it seems like the browser caching the redirect response was messing with me, so edit2 is wrong. See my response below. Edit2: disregard edit1, it doesn't seem like it's working after all. Edit: here's some further info: using this article I've managed to redirect from 'http://mysite.com/foo/bar/index.cgi' to 'http://www.mysite.com/index.aspx', but if I add the query string parameters, it still redirects to 'http://www.mysite.com/404.aspx' Isn't there a way to catch all requests to the cgi file, including query string parameters?

  • Standing and sitting while using a computer at work

    - by Adam Batkin
    I would like to be able to comfortably switch between sitting and standing while at work (I'm a software developer, so I spend most of my day in front of a computer). For the past couple of months I have been using a large elevated stand that sits on my desk (designed expressly for this purpose) containing my keyboard and mouse, and my monitors have been raised as high as possible and aimed upwards. So I can stand all day and I'm pretty comfortable (my right wrist may be at too much of an angle when it's on my mouse, but that's a separate issue). The only problem is that sometimes I want to be able to sit. I can easily place my keyboard and mouse back down under the elevated stand, but I have to look up pretty steeply and that is uncomfortable and makes it difficult to see the screens since they are tilted upwards. My monitor mounts are difficult to adjust quickly/easily, so I can't just re-aim them. I would of course love one of those hydraulic standing/sitting desks (cost isn't the problem). But I'm in a row of "trader-style" desks where it's basically a very long surface with people sitting at 6-foot intervals. What type of equipment do you recommend? I suppose the best thing would be some sort of monitor stand (it must be able to hold 2-3 LCDs) that can easily be lowered and raised. But any other suggestions are also welcome.

  • h264 inside FLV container vs. MP4 container?

    - by Gotys
    I am developing a tube site, and currently having issues with h264 format . By looking at youtube, I noticed they are putting their hi-def videos into mp4 container, so logically I did the same. Next, I installed mod_h264_streaming for lighttpd to make streaming and timeline-scrubbing work. Problem is, that large files (500mb+ at somewhat high resolution) take for EVER to even start buffering ( I read the flowplayer or other flash players need to download metadata first) . I moved the xmov atom to the front of the file with MP4Box (i tried qt-quickstart too) , and the problem didn't go away. Next I read online I need to interleave audio tracks, so I did that too. No change in slowness. So I tried putting the same exact h264 movie into an FLV container, and the playback buffering starts almost instantly - no slowness. So what am I missing here? Why would I choose MP4 container with mod_264_streaming module , which seems super-slow over a regular FLV container with lighttpd's built-in mod_flv_streaming ? Obviously many websites pick mp4 container , but I fail to understand why ? And as a side question - I tried using HTML5's VIDEO tag to try the same h264 MP4 movie, and the scrubbing is LIGHTING FAST! I looked into lighttpd's log file, and i noticed taht Flash Players append video.mp4?start=234 each time timeline is scrubbed, wheres HTML5's video tag does no such thing . Is this some sort of limitations of Flash ? Why Can't flash streaming be same fast as HTML5 streaming? Thanks to ALL who can help. I very much appreciate this community.

  • Why does 3.5 mm audio out work through headphones but not through external speakers?

    - by Rickster
    I have a computer that has a 3.5 mm audio jack on the front of it. The computer itself has no speakers, so this is the only way to hear sound. If I plug headphones into it, the audio properly plays through the headphones, and if I plug in external speakers it used to play through them as well. Just today I turned on my computer and the audio no longer plays through the speakers, but if I plug in the headphones instead it works. The speakers aren't broken, as both the speakers and headphones work in my iPod and play music. I thought that 3.5 mm jacks could not send data back to the computer, and the computer had no way of differentiating between different devices plugged into the jack. If this is true, how is it that the computer plays audio through the headphones but not through speakers plugged into the same 3.5 mm jack, and both devices are functional? Or is my knowledge on 3.5 mm jacks incorrect? I don't believe drivers are important, as the same driver runs the 3.5 mm jack for all devices, but if necessary I can provide additional information. Any ideas would be appreciated. Thanks!

  • 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.

  • Would a PHP application benefit from being served from a RAM drive?

    I am in charge of hosting a PHP application that is large and slow, but easy to scale. The application is entirely static, with writable disk storage needed. We've profiled the application, and the main bottleneck appears to come from loading the application and not the work the application does. The application is not CPU-intensive, although it does use a fair amount of memory (think Magento). Currently we distribute it by having a series of servers with the same PHP files on their hard drive and a load balancer in front of them. Easy but expensive. I've been reading about RAM disks and the IO benefits they offer, and was wondering if they would be well-suited to PHP applications. Since PHP applications are loaded from disk for every request and often involve lots of different files (as opposed to being kept in memory like with a Java application), I would figure that disk performance can be a severe bottleneck. Would placing the PHP files on a RAM disk and using the mount point as Apache's document root offer performance benefits? A startup script could create the RAM drive and then copy the files (which are plain-text and small) from a permanent location to the temporary RAM drive. Does this make sense, or should I just trust the linux kernel to cache the appropriate files in memory by itself?

  • Windows Server wbadmin recover with commas

    - by dlp
    I want to do a recovery of files with commas in their names from the command line, ala: wbadmin start recovery -version:10/01/2013-12:00 -itemType:File -overwite:Overwrite -quiet "-Items:C:\Path\To\File, With Comma.txt,C:\Path\To\File 2, With Comma.txt" So there are two files: C:\Path\To\File, With Comma.txt C:\Path\To\File 2, With Comma.txt The problem is wbadmin assumes commas separates each file, so it sees 4 files specified instead of 2. I've tried putting a \ in front of commas that are part of the file names like so: wbadmin start recovery -version:10/01/2013-12:00 -itemType:File -overwite:Overwrite -quiet "-Items:C:\Path\To\File\, With Comma.txt,C:\Path\To\File 2\, With Comma.txt" but it doesn't work, it just says there's a syntax error. The documentation on Technet doesn't seem to mention anything that'll help either. OS is Windows Server 2008 R2. A clarifying comment: I've changed the file names to be different than the actual names to be less revealing, but I also see I dumbed it down too much. The comma can occur either in the file name itself like C:\Path\To\File, With Comma.txt' or in the path to the file, like:C:\Path, To\Other\File.txt`.

  • Mod_pagespeed, Varnish and Apache cache issues after new code pushes

    - by WerkkreW
    I have a rather strange issue. In my environment we are running a load balanced cluster of 8 apache servers with a master-master MySQL backend. In front of apache we have Varnish in the cache layer. We have been running Apache mod_pagespeed for several weeks now and for the most part it has been working great. The issue arises when we do fresh code updates from Git, and and/all of the JS/CSS assets change. Basically the problem appears to be two fold. One, after the code push we generally take the opportunity to flush varnish, restart apache, and restart varnish. In doing this all of the mod_pagespeed combinied/minified files are cleared out ensuring that all of the new JS/CSS assets are fresh. The problem is, upon doing this the file names that mod_pagespeed creates change, but the old files (appear) to be still cached for many people client side leading to very unexpected results. However, if we do not restart apache, the changes to the files may or may not appear client side due to the cached minified assets. The simple solution is to disable mod_pagespeed, however I would rather not do that as it has made a fairly large impact in performance. I feel as if there must be a better way to deal with the inconsistencies in cache between the client and server to prevent having people to go to great lengths or perform a large number of page refreshes to see a working page. I can provide configuration snippets if anyone needs them.

  • VLC Crash when playing MKV files in Windows 7

    - by Phelios
    I'm not sure if the mkv file is corrupted, but when it is opened with VLC player, VLC loads up and displays nothing. Can't even close VLC after that. And also, VLC is running with 50% of the CPU. I have to use End Process to kill it. How do I know if the file is corrupted?
