  • Secure PHP environments with PHP-FPM and SFTP

    - by pdd
    I'd like to set up secure environments for a small number of untrusted PHP websites on a Debian server. Right now everything runs on the same Apache2 with mod_php5 and vsftpd for administrative file access, so there is room for improvement. The idea is to use nginx instead of apache, SFTP through OpenSSH instead of vsftpd and chrooted (in sshd_config), individual users for each website with their own pool of PHP processes. All these users and nginx are part of the same group. Now in theory I can set 700 permissions on all PHP scripts and 750 on static files that nginx has to serve up. Theoretically, if a website is compromised all the other users' data is safe, right? Are there better solutions that require less setup time and memory per website? Cheers

  • Windows boots to Black Screen of Death — Is my HDD faulty?

    - by Flynn1179
    My wife's PC suddenly stopped booting up properly. It gets as far as the Windows 'loading' screen with the bar scrolling away, but that's as far as it gets for some time, then suddenly flashes up a BSoD barely long enough to see, then the display cuts out. We've got identical PCs, and after swapping components, I established that my PC suffers the same problem if I swap in the HDD. Even if I plug hers in as a second HDD on my machine, it still does the same thing, even though it's booting from mine. I can't even boot her machine from CD or DVD either, so I couldn't even use a recovery disc. I did manage to partially boot my PC into safe mode with the other HDD attached, and it got as far as loading 'crcdisk.sys' and froze. Anybody know what could be wrong with it, or at least how I can get the data off the disk? I'm assuming there's still data on the disk, given that it at least shows me the vista 'loading' screen.

  • What are the common Control combinations in a terminal setting

    - by Hamish Downer
    I would like to have a good guide to the common Control key combinations in use in bash (and similar) shells and the combinations used by common programs in use in those shells. My particular motivation is to be able to run GNU screen on one computer, ssh to a second computer and use screen and irssi on that computer. So I need to use something other than Ctrl-A to control one of the screen sessions. So I need to know what are Control key combinations are safe to use. But I imagine this list would be useful for others who want to bind custom actions to Control key combinations. I reckon we'd be best to group the Control key combinations by application (eg. bash itself, screen, vim, emacs), to make it easy to spot the applications you use or can ignore. So please one application per answer - hope that works.

  • Linux's best filesystem to work with 10000's of files without overloading the system I/O

    - by mhambra
    Hi all. It is known that certain AMD64 Linuxes are subject of being unresponsive under heavy disk I/O (see Gentoo forums: AMD64 system slow/unresponsive during disk access (Part 2)), unfortunately have such one. I want to put /var/tmp/portage and /usr/portage trees to a separate partition, but what FS to choose for it? Requirements: * for journaling, performance is preffered over safe data read/write operations * optimized to read/write 10000 of small files Candidates: * ext2 without any journaling * BtrFS In Phoronix tests, BtrFS had demonstrated a good random access performance (fat better than XFS thereby it may be less CPU-aggressive). However, unpacking operation seems to be faster with XFS there, but it was tested that unpacking kernel tree to XFS makes my system to react slower for 51% disregard of any renice'd processes and/or schedulers. Why no ReiserFS? Google'd this (q: reiserfs ext2 cpu): 1 Apr 2006 ... Surprisingly, the ReiserFS and the XFS used significantly more CPU to remove file tree (86% and 65%) when other FS used about 15% (Ext3 and ... Is it same now?

  • Dell Media Direct is rebooting my machine when it goes into sleep mode

    - by wsanville
    I've got a Dell Studio 1535 laptop, which shipped w/ Vista 32-bit. I've since formatted and installed Windows 7 64-bit. Everything has been fine for months, but recently, every time I leave my machine unattended and it goes to sleep, it wakes with the Dell Media Direct splash screen, and then goes to the "Windows was not shut down properly..." dialog that asks if you want to boot safe mode/start Windows normally/etc. The stupid button is also stuck on currently, but even when it is off, the problem still occurs. From the searching I've done, I've learned that the program is installed on its own partition, but I'm fairly certain I formatted everything. See screenie of my partitions: How can I stop the madness? Update: I've removed the 39 MB OEM Partition and it is still happening.

  • Windows 7 laptop's volume with headphones way too loud

    - by jcao219
    I have two headphones, neither has any amps or volume control, and both have the same problem with this computer. I normally have the volume on 10%, and that is optimal. I'm still very afraid that someday it will be at 100% and i'll accidentally have my headphones on. I tested how loud it is at maximum volume -- it's earsplittingly loud! In fact, it's so loud that if I lay the headphones down on the table, I can listen to a song perfectly clearly from meters away. Is there any way to make the volume control more safe for the ears?

  • Web Server Scripting Hack to Maintain State and Keep a Domain Cookieless

    - by jasonspalace
    Hello, I am looking for a solution on a LAMP server to keep a site cookieless such as "example.com", where static content is served from "static.example.com", and with rules in place to rewrite requests for "www.example.com" to "example.com". I am really hoping to avoid setting up a cookieless domain for the static content due to an unanswered SEO concern with regards to CNAMEing to a CDN. Is there a way, (or safe hack), that can be implemented where a second domain such as "www.example2.com" is CNAMEd, aliased, or otherwise used with "example.com" to somehow trick a php application into maintaining state with a cookie dropped on "www.example2.com" therefore keeping all of "example.com" cookieless? If such a solution is feasible, what implications would exists with regards to SSL and cross-browser compatibility other than requiring users to accept cookies from 3rd party domains and possibly needing an additional SSL to keep the cookie secure? Thanks in advance to all.

  • Individual pst files for individual outlook 2010 folders

    - by Jack
    I was wondering if it is possible for the following scenario: Suppose I have 5 folders in my Microsoft Outlook 2010. Currently, there are 1 pst file that contain the 5 folders. Each folders contain emails that are grouped according to the folder name. So, can I have 5 pst file, whereby 1 pst file for 1 folder? This is because at some other time, I will create new folder(s) and existing folder I may remove from Outlook (but still able to make a copy of the pst file)

  • "macros have been disabled" message in Word 2007 but no macros

    - by Loftx
    Hi there, I open a .doc file in Word 2007 (sorry I am unable to supply the .doc) which pops up with a message above the document "Security warning: Macros have been disabled" but there are no macros shown in the macros listing and no functionality displayed in the VBScript editor. Why does Word think this document contains macros and how can I remove them to prevent the warning? Thanks, Tom

  • Resizing RAID 1 Array on Dell PowerEdge with Perc 4/Di & Windows SBS 2003

    - by Scott McKinney
    I have a Dell PowerEdge 2600 with Perc 4/Di RAID card and Windows SBS 2003 installed. The original system drive was a set of 17GB drives in a RAID 1 array. Over the years, these drives have failed (individually) and been replaced by a set of 73GB drives, but the RAID array is still 17GB in size. Is there a safe procedure to resize the RAID 1 array to use the entire 73GB without destroying/corrupting the data on the array? The Perc documentation mentions a Reconstruct option with Online Capacity Expansion, but is a woefully short on the exact details. Has anyone performed this procedure successfully (or unsuccessfully)? What were the steps? Are there any gotchas I should watch out for?

  • Apache2 - mod_expire and mod_rewrite not working in httpd.conf - serving content from tomcat

    - by Ankit Agrawal
    I am using apache2 server running on debian which forwards all the http request to tomcat installed on same machine. I have two files under my /etc/apache2/ folder apache2.conf and httpd.conf I modified httpd.conf file to look like following. # forward all http request on port 80 to tomcat ProxyPass / ajp://127.0.0.1:8009/ ProxyPassReverse / ajp://127.0.0.1:8009/ # gzip text content AddOutputFilterByType DEFLATE text/plain AddOutputFilterByType DEFLATE text/html AddOutputFilterByType DEFLATE text/xml AddOutputFilterByType DEFLATE text/css AddOutputFilterByType DEFLATE text/javascript AddOutputFilterByType DEFLATE application/xml AddOutputFilterByType DEFLATE application/xhtml+xml AddOutputFilterByType DEFLATE application/rss+xml AddOutputFilterByType DEFLATE application/javascript AddOutputFilterByType DEFLATE application/x-javascript DeflateCompressionLevel 9 BrowserMatch ^Mozilla/4 gzip-only-text/html BrowserMatch ^Mozilla/4\.0[678] no-gzip BrowserMatch \bMSIE !no-gzip !gzip-only-text/html # Turn on Expires and mark all static content to expire in a week # unset last modified and ETag ExpiresActive On ExpiresDefault A0 <FilesMatch "\.(jpg|jpeg|png|gif|js|css|ico)$" ExpiresDefault A604800 Header unset Last-Modified Header unset ETag FileETag None Header append Cache-Control "max-age=604800, public" </FilesMatch RewriteEngine On # rewrite all www.example.com/content/XXX-01.js and YYY-01.css files to XXX.js and YYY.css RewriteRule ^content/(js|css)/([a-z]+)-([0-9]+)\.(js|css)$ /content/$1/$2.$4 # remove all query parameters from URL after we are done with it RewriteCond %{THE_REQUEST} ^GET\ /.*\;.*\ HTTP/ RewriteCond %{QUERY_STRING} !^$ RewriteRule .* http://example.com%{REQUEST_URI}? [R=301,L] # rewrite all www.example.com to example.com RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC] RewriteRule ^(.*)$ http://example.com/$1 [R=301,L] I want to achieve following. forward all traffic to tomcat GZIP all the text content. Put 1 week expiry header to all static files and unset ETag/last modified header. rewrite all js and css file to certain format. remove all the query parameters from URL forward all www.example.com to example.com The problem is only 1 and 2 are working. I tried a lot with many combinations but the expire and rewrite rule (3-6) do not work at all. I also tried moving these rules to apache2.conf and .htaccess files but it didn't work either. It does not give any error but these rules are simple ignored. expires and rewrite modules are ENABLED. Please let me know what should I do to fix this. 1. Do I need to add something else in httpd.conf file (like Options +FollowSymLink) or something else? 2. Do I need to add something in apache2.conf file? 3. Do I need to move these rules to .htaccess file? If yes, what should I write in that file and where should I keep that file? in /etc/apache2/ folder or /var/www/ folder? 4. Any other info to make this work? Thanks, Ankit

  • How to convert an image to a .dwg file

    - by erikric
    My girlfriend is making an art project where she is having an image printed and cut out on a metal plate. The firm responsible for doing this is demanding a .dwg file (and something called polyline; some sort of setting maybe?). Neither of us have heard about this file format, and I find the information about it quite confusing. Most pages seem to link to some schetchy "FooToBarConverter" software, that I frankly don't trust. Could someone please enlighten us on what we need to do, or point to some safe and preferably free software that could do this? (An explanation of the dwg format and the polyline thing would also be much appreciated)

  • Local Password Management

    - by ultimazombie88
    In our office (and I am sure many others) we access various websites and tend to share one account with our team. For example, we share credentials to Ebay and change them every few weeks to maintain some sense of security. However, we know this does not allow for any type of accountability for major changes. After some discussion we want to try to manage how we distribute credentials for sites that may not offer child accounts. Is there any smart and safe way to do this? If so how do you do it?

  • Asus G53SX How to use the recovery partition

    - by Amento
    I am trying to use the recovery partition on my Asus G53SX laptop, but the instructions in the included booklet don't match up with what happens on the computer. It says press F9 during bootup and then press ENTER to select windows setup. Then select the language you want to recover, and so on. When I press F9 I end up in the boot manager and from there I can access safe mode and all these things. The closest thing I can find in this list is "Repair your computer" but this menu takes me to recovery points and backup images, none which are mentioned in the booklet. How can I use the recovery partition to restore my laptop to factory state?

  • Upgrading openSUSE 11.1 with Plesk Panel 9.3 to PHP 5.3

    - by Jonathan
    I'm running a VPS with openSUSE 11.1 (i586). On the VPS is Parallels Plesk Panel 9.3.0 installed. The current PHP-version is PHP 5.2.11. I want to upgrade PHP to PHP 5.3, but I can't find good instructions on how to do this. If I check for updates in Zypper, it says this is the latest release. In the Plesk Updates isn't an update either, both via the webbased interface and the command line interface. On Software.openSUSE.org I can find packages for PHP 5.3.1 in both the server:php/server_apache_openSUSE_11.1-repo and the server:php/openSUSE_11.1-repo (can't post the link because I'm a newbie here). But if I add one of those to Zypper, I still don't see an update. Is there here somebody who knows how to do this? And is it completely safe to update that way? I don't want to end up with a broken VPS... Thanks! Jonathan

  • Sun Tool-less Slide Rails Removal for X4150

    - by Ablue
    I have some tool-less slide rails for some 1ru x4150 sun servers. I can't seem to see how to remove them. Sun in their wisdom did not include this seemingly important information in their documentation; they simply (possibly with a cheeky smile) say to... "Refer to the (long since lost) installation card included with the rackmount kit for instructions on attaching tool-less slide-rail assemblies to the rack." So if anyone knows please let me know.

  • Removing English - United States Language from Firefox Issue...

    - by Paul
    Win7 Home Prem 32bit Firefox 3.6.2 I noticed whilst typing a hotmail email in Firefox that the default language seems to be English/United States. As i am from the UK i thought i would add in the English/United Kingdom dictionary Addon which i have done. I have set this as the default Language. Is there anyway to remove the English/United States Dictionary? It is not an Addon so i'm guessing it's the built in Firefox default language and may be unremovable?

  • Python2.7 / Pip2.7 install in Centos6: root does not see /usr/local/bin

    - by Erotemic
    I am trying to install Python2.7 in Centos 6. It's a pain as centos6 ships with python26 and yum is dependent on it. Furthermore yum does not seem to have python2.7 I ended up building it from source: wget https://www.python.org/ftp/python/2.7.6/Python-2.7.6.tgz gunzip Python-2.7.6.tgz tar -xvf Python-2.7.6.tar cd Python-2.7.6 ./configure --prefix=/usr/local --enable-unicode=ucs4 --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib" make sudo make altinstall cd ~ This installed python2.7 to /usr/local/bin and I can use it. But I cannot call it with sudo unless I specify the whole pathname To install pip I had to do: wget https://bootstrap.pypa.io/get-pip.py sudo /usr/local/bin/python2.7 get-pip.py Now whenever I want a package I have to call sudo /usr/local/bin/pip2.7 install somepackage Is there a clean way to be able to run: sudo pip2.7 install somepackage without having to specify the absolute path? Is a symlink into /usr/bin safe?

  • Looking for Driver Diagnostic and Repair Software

    - by risingTide
    Greetings, I am currently plagued with BSODS on startup (both normal and safe mode) for my XP Pro. After much troubleshooting I have determined it is a driver problem. However, because I cannot even boot I do not know how to fix it. I am looking for some specific driver diagnostic and repair software that I can use from another computer to access and fix the driver problem on the problematic XP drive. (I can access the problematic drive via USB from another computer.) I will offer more details about my specific situation if it is helpful or necessary. Thank you for your time!

  • Ubuntu 12.04 boot degraded raid

    - by beacon_bonanza
    I've installed Ubuntu 12.04.1 in a new server and set up the 4 hard drives with 3 RAID 1 devices, the configuration is such that the first two drives have md0 (swap space) and md1 (/) with the third and fourth drives having md2 (/var). I've been testing the operation under a drive failure and found that the system boots fine if I remove disk two but if I remove disk one then the system gets to grub and then just restarts. I'm confused as to why grub appears to be loading properly from disk two but then the boot fails. I've tried to copy the MBR from disk 1 to 2: dd if=/dev/sda of=/dev/sdb bs=512 count=1 but this didn't make a difference.
