  • Issue with permanent redirect implementation

    - by Argoron
    I have a tricky problem related to 301 redirections I badly need help with. I tried to implement these via .htaccess, but ran into trouble. The start of my .htaccess looks like this: SetEnv PHP_VER 5 Options +FollowSymlinks RewriteEngine on # Redirect non-www to www RewriteCond %{HTTP_HOST} !^(www\.|$) [NC] RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L] #--- GENERAL --- RewriteRule ^index\.html$ index.php [L] ... When I try to put a permanent redirect to index.php by adding R=301 in the square brackets, I get a 404, and I have no idea where the error comes from.

  • Enable 'mod_rewrite' Using .htaccess File On cPanel Shared Hosting Server

    - by zulhfreelancer
    I'm using cPanel to host my website. I need to enable 'mod_rewrite' on this Shared Hosting cPanel account to run my script. I've tried to Google the solutions high and low but did not find any luck yet. Those tutorials that I found only work well with VPS and some of them said that, only hosting provider can change and enable it. But, some of them said that, it can be done easily by editing the .htaccess file. My question: If I want to edit the .htaccess file, what should I include in that file? What the 'rules' and 'conditions' that should be included?

  • Transparent PHP script execution using mod_rewrite

    - by tori3852
    I am looking for a solution for this a problem: I need that every HTTP request (method is irrelevant) in Apache http server would be served only after execution of specific PHP script. This is needed because I need to gather some information about requests, etc. As far as I understand - this could be achieved using mod_rewrite module. So far I have done this (in .htaccess file): RewriteEngine on RewriteRule ^(.*)$ script.php [C] script.php is executed, but I need that after this original request would be executed. Thanks - any help is appreciated.

  • Help with URL Rewrite

    - by bodesam
    This is the first time i'm doing this and have been doing some research on it. I have a page that selects some info from a database and displays it with a link to a second page that uses the result to query the database, something like this: $sel=mysql_query("select id, title from thetable "); while($row=mysql_fetch_array($sel)) { $id=$row['id']; $title=$row['title']; echo "<a href='more.php?id=$id'>$title</a>"; } The issue is, in the more.php page, instead of more.php?id=5 to show in the address bar, I want something like more/title Secondly, as it obtains in most sites, I want the link on the referring page to show this friendly url on mouse hover not the more.php?id=5 And I notice in most sites some words like 'a', 'and', 'the' etc are usually removed from the url title(even if there originally), moreover how does one handle the situation where more than one record have the same title. How does one go about achieving this url rewrite with htaccess or whatever method is used. Thanks.

  • RewriteRule for URLs with spaces

    - by Robert Cailliau
    My site's pages are in multiple languages whereby each language version shares its media (images) with the other language versions. I place all versions and the media in a single directory with the same name. E.g. pages mypage-en.html, mypage-fr.html etc. will sit in directory mypage. The directory path suffices to reference a page: h t t p : //....../mypage/ is good enough, there is no need for h t t p : //....../mypage/mypage-en/html A rewrite with RewriteRule ^(.*)/([a-zA-Z0-9]+)/?$ /$1/$2/$2-en.html lets me use the shorter form. But what if the name mypage contains spaces (which some do) ? I want h t t p : //....../my page/ to lead to h t t p : //....../my page/my page.html Using RewriteRule ^(.*)/([a-zA-Z0-9|\s]+)/?$ /$1/$2/$2-en.html did not work. Any hints welcome. (please do not ask me why I want to do this, nor tell me I should not use spaces in file names)

  • Simple mod_rewrite Question

    - by user5358
    Hello, I want to have everything that looks like this: /1/2/3/4/5/[...] to redirect to this: /index.php?u=/1/2/3/4/5/[...] unless the requested string is a specific file. So anything that doesn't have a ".", I want to redirect to "index.php?u=[...]". I'll then parse the URI segments in PHP to determine what the user is requesting. I've been looking around for how to do this, but have only a very rough understanding of regular expressions and have been unable to find an example of how to do it. Thanks!

  • .htaccess two different rules but only one per time

    - by dragon112
    I'm rather new to the whole .htaccess thing and I'm using the following right now to use 'pretty url's': <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php?path=$1 [NS,L] </IfModule> Now i found my website a bit slow and decided to start gzipping my CSS files thru a php script I found somewhere on the web (the website). For this to work I need to rewrite the url to open the correct php file. That would look something like this: RewriteRule ^(.*).css$ /csszip.php?file=$1.css [L] But I only want the first to happen when the second doesn't and vice versa. In other words i'd like something like this: <IfModule mod_rewrite.c> RewriteEngine On if request doesn't contain .css do RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php?path=$1 [NS,L] else do RewriteRule ^(.*).css$ /csszip.php?file=$1.css [L] </IfModule> Can anyone help me with the proper code or a place where i can find a way to use some kind of conditional statement in htaccess files? Thanks in Advance!:)

  • SQL IO and SAN troubles

    - by James
    We are running two servers with identical software setup but different hardware. The first one is a VM on VMWare on a normal tower server with dual core xeons, 16 GB RAM and a 7200 RPM drive. The second one is a VM on XenServer on a powerful brand new rack server, with 4 core xeons and shared storage. We are running Dynamics AX 2012 and SQL Server 2008 R2. When I insert 15 000 records into a table on the slow tower server (as a test), it does so in 13 seconds. On the fast server it takes 33 seconds. I re-ran these tests several times with the same results. I have a feeling it is some sort of IO bottleneck, so I ran SQLIO on both. Here are the results for the slow tower server: C:\Program Files (x86)\SQLIO>test.bat C:\Program Files (x86)\SQLIO>sqlio -kW -t8 -s120 -o8 -frandom -b8 -BH -LS C:\Tes tFile.dat sqlio v1.5.SG using

However, the 64 write test is incredibly slow on the rack server. (68 mb/sec on the slow tower vs 21 mb/s on the rack). The read speed for 64k also seems slow. Is this enough to say there is some sort of bottleneck with the shared storage? I need to know if I can take this evidence and say we need to launch an investigation into this. Any help is appreciated.

  • Benchmarking a file server

    - by Joel Coel
    I'm working on building a new file server... a simple Windows Server box with a few terabytes of disk space to share on the LAN. Pain for current hard drive prices aside :( -- I would like to get some benchmarks for this device under load compared to our old server. The old server was installed in 2005 and had 5 136GB 10K disks in RAID 5. The new server has 8 1TB disks in two RAID 10 volumes (plus a hot spare for each volume), but they're only 7.2K rpm, and of course with a much larger cache size. I'd like to get an idea of the performance expectations of the new server relative to the old. Where do I get started? I'd like to know both raw potential under different kinds of load for each server, as well an idea of what our real-world load looks like and how it will translate. Will disk load even matter, or will performance be more driven by the network connection? I could probably fumble through some disk i/o and wait counters in performance monitor, but I don't really know what to look for, which counters to watch, or for how long and when. FWIW, I'm expecting a nice improvement because of the benefits of having two different volumes and the better RAID 10 performance vs RAID 5, in spite of using slower disks... but I'd like to get an idea of how much.

  • What causes "A disk read error occurred, Press Ctrl + Alt + Del to restart"?

    - by Mehrdad
    I have a virtual machine containing Windows XP SP3. When I resized the VHD file (and the embedded partition), and tried booting, I got: A disk read error occurred Press Ctrl + Alt + Del to restart Some notes: FixBoot and FixMBR don't help. ChkDsk doesn't help. The partition is indeed active. The partition starts at sector 63 (it also did so before the problem) of cylinder 1, head 1, and is marked as type 0x07 (NTFS) My host OS reads the VHD and the partition completely fine I'm interested in knowing the cause rather than the fix. So "re-format the disk", "reinstall Windows", etc. aren't valid solutions. It's a virtual machine after all... I have nothing to lose, so I don't care about fixing it. I just want to know what's causing this problem, in case I run into it again on a physical machine (which I have done before).

  • Robocopy silently missing files

    - by John Hunt
    I'm using Robocopy to sync data from our server's hard disk to an external disk as a backup. It's a pretty simple solution but pretty much the best/easiest one we could come up with - we use two external disks and rotate them offsite. Anyway, here's the script (with the comments taken out) that I'm using to do it. It works very well, it's quick and almost 100% complete - however it's acting pretty strange with a few files (note company name has been changed in paths to protect the innocent): @ECHO OFF set DATESTAMP=%DATE:~10,4%/%DATE:~4,2%/%DATE:~7,2% %TIME:~0,2%:%TIME:~3,2%:%TIME:~6,2% SET prefix="E:\backup_log-" SET source_dir="M:\Company Names Data\Working Folder\_ADMIN_BACKUP_FILES\COMPA AANY Business Folder_Backup_040407\COMPANY_sales order register\BACKUP CLIENT FOLDERS & CURRENT JOBS pre 270404\CLIENT SALES ORDER REGISTER" SET dest_dir="E:\dest" SET log_fname=%prefix%%date:~-4,4%%date:~-10,2%%date:~-7,2%.log SET what_to_copy=/COPY:DAT /MIR SET options=/R:0 /W:0 /LOG+:%log_fname% /NFL /NDL ROBOCOPY %source_dir% %dest_dir% %what_to_copy% %options% set DATESTAMP=%DATE:~10,4%/%DATE:~4,2%/%DATE:~7,2% %TIME:~0,2%:%TIME:~3,2%:%TIME:~6,2% cscript msg.vbs "Backup completed at %DATESTAMP% - Logs can be found on the E: drive." :END Normally the source would just be M:\Comapany name data\ but I altered the script a bit to test the problem. The following files in the source are not copied to the dest: Someclient\SONICP~1.DOC Someclient\SONICP~2.DOC Someclient\SONICP~3.DOC However, files in the same directory named: TIMESH~1.XLS TIMESH~2.XLS are copied. I'm able to open the files that aren't copied with no trouble at all, and they certainly weren't opened when I ran robocopy so it's not a locking issue. Robocopy is running as administrator so it's not a permissions issue. There's no trace these files were even attempted to be copied as there are no errors being output in the log or in my command prompt. Does anyone have any suggestions as to what this might be? Busted hard disk? Cheers, John.

  • How can I mount dd image of a partition?

    - by Puneet Arora
    I created a dd image of a partition (containing an HFS+ FS) of one of my disks (and not the entire disk) a few days ago using the following command - dd conv=sync,noerror bs=8k if=/dev/sdc2 of=/path/to/img How can I mount it? I tried the following but it doesn't work - mount -o loop,ro -t hfsplus /path/to/img /path/to/mntDir It gives me mount: wrong fs type, bad option, bad superblock on /dev/loop1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so and dmesg | tail gives me - [5248455.568479] hfs: invalid secondary volume header [5248455.568494] hfs: unable to find HFS+ superblock [5248462.674836] hfs: invalid secondary volume header [5248462.674843] hfs: unable to find HFS+ superblock [5248550.672105] hfs: invalid secondary volume header [5248550.672115] hfs: unable to find HFS+ superblock [5248993.612026] hfs: unable to find HFS+ superblock [5248998.103385] hfs: unable to find HFS+ superblock [5249031.441359] hfs: unable to find HFS+ superblock [5249036.274864] hfs: unable to find HFS+ superblock Is there something wrong that I am doing? I tried searching on how to do this but all the results I get only talk about mounting a partition from within a full disk image, using the offset option with mount - none talk about the case where the image itself is that of a partition. Thanks. PS: I'm running 64bit Arch Linux, and the partition from the original disk /dev/sdc2 mounts fine.

  • Access denied to external USB disk; update access rights fails in Windows 8

    - by gerard
    I use to work with 2 laptops (Windows vista and Windows 7), my work files being on an external usb disk. My oldest laptop broke down, so I bought a new one. I had no option other than take Windows 8. I suspect something changed with access rights, as my external disk suffered some "access denied" problem on Windows. I was prompted (by Windows 8) somehow to fix the access rights, which I tried to do, getting to the properties - security. This process was very slow and ended up saying disk is not ready Additionally, my external usb disk somehow was not recognized anymore. Back to Windows 7, I was warned that my disk needed to be verified, which I did. In this process, some files were lost (most of them I could recover from the folder found00x, but I have some backup anyway). Also, I don't know why, but under Windows 7, all the folder showed with a lock. Then back again to Windows 8. Same problem : access denied to my disk + no way to change access rights as it gets stuck disk is not ready". Now I am pretty sure there is some kind of bug or inconsistency in Windows 8 / Windows 7. I did 2. and 3. a few times. At some point, I also got an access denied in Windows 7. I could restore access rights to the disk to "System" (properties - security - EDIT for full control to group "system". ). But then I still get the same access right pb on Windows 8, and getting stuck in the process to restore full control to "system" -- and "admin" groups. I upgraded Windows8 with the Windows8 updates available. Does not help.

  • Aging SBS needs updates / Thoughts for one-off, off-line complete backup?

    - by tcv
    Hey guys, So, we checked out the status of an SBS 2003 at one of our more recent, spend-averse clients and found it to be woefully out-of-date. Scary out of date. I think it's running IE2. Ok, maybe not that far back. Anyway, I was thinking that I could use some kind of disk-imaging software to image the four IDE drives within and, in the event the server gets some kind of Update Induced Indigestion, I could completely restore. Usually my go-to software for this is Acronis, but my client will likely balk at a $500 price tag for a one-off backup with their server product. I had thought we could use the boot media from, say, Backup & Recovery 10 to take an off-line image of all the drives. According to their CHAT tech support, however, it will not work. I pressed for the technical reasons and they said they'd email me. They haven't emailed me. They still might. This server is running SBS 2003, pre sp2. It's got four IDE disks. One is a Basic disk, which contains the O/S. The others are bound as a dynamic disk. You might ask: "Don't they already have backup software?" They do! Backup Exec, a very low-end version that won't even do VSS. I don't know much about BE, but it seems to me that if the worst were to happen, it would mean building a new server O/S, installing BE (if the media is available), then restoring. Would it even work? I can take the system down for hours to do a backup and my goal here is a pretty dead-simple restore if the worst happens. Any and all suggestions are exciting. m

  • SSD suddenly full

    - by Daniel
    Today the hard drive of our server was suddenly full. The disk usage always stayed around 50 % in the weeks and months before (old data is regularly expunged from the server). I deleted 10 GB of files in /tmp, which strangely freed 51 GB. Here is what I did: root@***:~# df -h Dateisystem Size Used Avail Use% Eingehängt auf /dev/sda3 139G 137G 0 100% / tmpfs 3,9G 0 3,9G 0% /lib/init/rw udev 3,9G 116K 3,9G 1% /dev tmpfs 3,9G 0 3,9G 0% /dev/shm /dev/sda1 985M 25M 910M 3% /boot root@***:/var# du -hs * 3,3M backups 438M cache 9,4G lib 4,0K local 12K lock 76M log 24K mail 4,0K opt 88K run 184K spool 10G tmp 12K www root@***:/var/tmp# find -type f -print0 | xargs -0 rm root@***:/var/tmp# df -h Dateisystem Size Used Avail Use% Eingehängt auf /dev/sda3 139G 81G 51G 62% / tmpfs 3,9G 0 3,9G 0% /lib/init/rw udev 3,9G 116K 3,9G 1% /dev tmpfs 3,9G 0 3,9G 0% /dev/shm /dev/sda1 985M 25M 910M 3% /boot Any explanation as to why deleting 10 GB in /tmp gave me back 51 GB on the disk? Could this point to an SSD failure? Are there any tools for Debian to test SSD health? I already have checked syslog. The first entry relating to this incidient is a mysql message: 1:22:02 [ERROR] /usr/sbin/mysqld: Disk is full writing... So I have absolutely no idea what caused this.

  • RAID Array performance on an HP Proliant ML350 G5 Smart Array E200i

    - by Nate Pinchot
    We have a client who is complaining about performance of an application which utilizes an MS SQL database. They do not believe the performance issues are the fault of the application itself. The Smart Array E200i RAID controller has 128MB cache and we have the cache set to 75% read/25% write. The disk array set to enable write caching. Recently we ran a disk performance test using SQLIO based on this guide. We used a 10 GB file for the test found that the average sequential read rate was ~60 MB/sec (megabytes/sec) and the average random read rate was ~30 MB/sec. Are these numbers on par for what the server should be performing? Better than on par? Horrible? Amazing?

  • NVRAM for journals on Linux?

    - by symcbean
    I've been thinking about ways of speeding up disk I/O, and one of the bottlenecks I keep coming back to is the journal. There's an obvious benefit to using an SSD for the journal - over and above just write caching unless of course I just disable the journal with the write cache (after all devicemapper doesn't seem to support barriers). In order to get the benefits from using a BB write cache on the controller, then I'd need to disable journalling - but then the OS should try to fsck the system after an outage. Of course if the OS knows what's in the batter-backed memory then it could use it as the journal - but that means it must be exposed as a block device and only be under the control of the operating system. However I've not been able to find a suitable low-cost device (no, write-levelling for Flash is not adequate for a journal, at least one which uses Smartmedia). While there's no end of flash devices, disk/array controllers with BB write caches, so far I've not found anything which just gives me non-volatile memory addressable as a block storage device.

  • Issues with Apache redirect to www-prefixed URL

    - by lamp_scaler
    I have a website with domain mysite.com. I would like to have it so that if a user types in "mysite.com" it will redirect to "www.mysite.com". Additionally, "mysite.com/subdir" will also redirect to "www.mysite.com/subdir". I've looked and made changes with vhosts and also rewrites, but it's not working for the "mysite.com/subdir"-"www.mysite.com/subdir" case. Every time I type in "mysite.com/subdir", it will redirect to "www.mysite.com". Only "www.mysite.com/subdir" works. Not sure how to troubleshoot this. I turned on rewrite logs and didn't see anything obvious, yet. This is my config files so far. Please let me know what I'm missing. Thanks!

  • Programmatically measure size and way-order of L1 and L2 caches

    - by osgx
    How can I measure programmatically (not query the OS, but measure) the size and order of associativity of L1 and L2 caches (data caches)? Assumptions about system: It has L1 and L2 cache (may be L3 too, may be cache sharing), It may have a hardware prefetch unit (just like P4+), It has a stable clocksource (tickcounter or good HPET for gettimeofday). There are no assumptions about OS (it can be Linux, Windows, or something non-standard), and we can't use POSIX queries. Language is C. And compiler optimizations may be disabled.
