  • Sending mail to local address crashes web server (sendmail)

    - by deceze
    When trying to send mail automatically from a script at example.com via PHP's mail() to [email protected], the Apache server throws an Internal Error. I believe internally it is configured to use sendmail. The message gets dropped into ~/dead.letter and the general error log reads: [Wed May 12 11:26:45 2010] [error] [client xxx.xxx.xxx.xxx] malformed header from script. Bad header=/home/example/dead.letter... S: /home/example/www/test.php Trying any other address, not @example.com, works just fine. I have googled and serverfaulted for solutions, but they all require to edit configuration files in /etc/mail and similar system places, which is not an option, since this problem occurs on a shared host in which I only have access to ~/. Does anyone have a suggestion?

  • How to export everything from Firefox to another PC

    - by ianix
    I'm going to do a clean install of Windows 7 in my laptop and one of the thing that I really want the way it is is Firefox. I know I can get the addons easily and the bookmarks also, but I also like to export my browsing history, the Awesome Bar database and my about:config customizations. Is there a way or tool to do that?

  • Multi-Application Server Environment and Memcached Security

    - by jocull
    We are looking to integrate Memcached into our infrastructure, but have a security concern before we do. We run several platforms including ASP.NET and Coldfusion and have many app developers working many little applications across the different platforms. The concern is this: App A places item "dog" into cache. App B reads item "dog" (or worse: App B updates item "dog") After this happens, App A either retrieves bad information, or has already had its information viewed, aka "stolen". What we would like to do is make it so that each app can only interact with its own sandbox, and may not interfere with or read other application's data. Is this possible? Thanks.

  • Real time mirroring between two sql server databases

    - by Matt Thrower
    Hi, I'm a c# programmer, not a DBA and I've had the (mis)fortune to be handed a database admin task. So please bear this in mind when answering this question. What I've been asked to do is to create a real time two-way mirror between two databases with a 10 Megabit connection between them. So when either changes it updates the other. This is not a standard data mirroring/failover task where one DB is the master and the other is a backup - both are live and each needs to instantly reflect changes made to the other. In my head this sounds like a tall order, one which may even be impossible - after all in a rapidly changing environment with lots of users this is going to be massively resource intensive and create locks and queues of jobs all over the place. Is it possible? If so, can anyone either give me some basic instructions and/or point me at some places to start my reading and research? Cheers, Matt

  • Windows Server 2008 Black Screen on boot

    - by Mark Milford
    Hi I have a windows server 2008 running in Parrallels (on Mac osx)... the mac crashed yesterday and so I hard rebooted it, when I fired up the Windows Server 2008 VM this morning it goes as far as the progress bar then goes black screen and does nothing else (even when left for a long time). I can boot into safe mode, Event Viewer says: "The following boot-start or system-start driver(s) failed to load: spldr stoflt" Any ideas? What should I do next?

  • How can we control the device driver load order in Windows XP ?

    - by Deniz
    We are trying to install both an HP scanner and a Kodak scanner on an XP machine and the problem is that that HP's scanner driver always places itself into the first and default scanner device position. We are using an automation software on that machine which must use the Kodak scanner as the default scanner. The HP flatbed isn't needed to be the default scanner on that machine. It will always be used manually and through its own software. Our developers did some research 2 years ago couldn't find a solution. Nowadays we are preparing to expand our user base and this problem did surface again on machines with the same configuration. I did a more aggresive search pn the net and found some tips like this one : http://support.microsoft.com/kb/115486 I couldn't realize how to suit this solution to my scenario. Could someone please point me to the right direction ?

  • Windows/Samba connection error

    - by Gomibushi
    I have a Linux fileserver serving up /home for linux and windows users. I was able to connect from my windows client, but not from a DC. Then suddenly I could connect from the DC too. The linux servers run Centrify clients, and as such are part of the domain. All on same subnet. This is what the the log.smbd says, repeatedly: [2010/02/11 11:25:57, 0] lib/util_sock.c:read_data(534) read_data: read failure for 4 bytes to client 192.168.200.3. Error = Connection reset by peer On Windows it appeared as an "unknown error". EDIT: the error code is "0x80004005". We are developing a system depended on the samba share, and are worried this will appear again. It would be nice to pin point the root of this. Any ideas what this might be? Places to look?

  • Different display arrangements for two identical displays

    - by Niels
    I have a MacBook Pro running OSX Lion and two workplaces with identical setups: at both places I have an 27" LED Cinema display. At one workplace my MacBook is on the left side of the external display, and at the other workplace it is on the right. I would like to have two different display arrangements for the two different setups, however, when I change the display arrangements in System Preferences when connected to one display, the arrangement is changed for the other display as well. I used to have a 27" and a 24" Cinema Display, and OSX used to remember the display arrangements for those different displays, but now the displays are identical, so they use the same arrangements setting. Is there any way to tell OSX to handle two identical displays as different ones so I can configure two different arrangements for the two setups?

  • SELinux adding new allowed samba type to access httpd_sys_content_t?

    - by Josh
    allow samba_share_t httpd_sys_content_t {read execute getattr setattr write}; allow smbd_t httpd_sys_content_t {read execute getattr setattr write}; I am taking a stab in the dark with resources I've looked at, at various places that the above policies are what I want. I basically want to allow Samba to write to my web docs without giving it free access to the operating system. I read a post by a NSA rep saying the best way was defining a new type and allowing both samba and httpd access. Setting the content to public content (public_content_rw_t) does not work without making use of some unrestrictive booleans. To state this in short, how do I allow samba to access a new type?

  • Make browsing safe for porn surfers

    - by Brett G
    At several places I've done some work at, I have a suspicion that some of the executives browse porn on their work computers. It appears this porn surfing has lead to virus infections on their computers despite the presence of an anti-virus. Filtering theses specific users' browsing is not an option, so what would be my next best solution be? I put Firefox + Adblock pro on their computers. I'm tempted to add NoScript, but I'm worried they'll start calling when noscript interferes with browsing on legit websites. Is there anything else I can due to mitigate this risk?

  • Unable to bring back terminal launcher in fedora

    - by Sandeepan Nath
    Our office housing keeping guy sat on my linux (Fedora 7) system and somehow removed the main panel. By panel I mean where all the menus are there - Applications, Places, System etc. and contains a tab for every running application. I brought back the panel but now I don't see the terminal launcher and I can't find it anywhere. It used to be there in "Applications - System Tools - Terminal" but now the System Tools option itself is not present there. System - Preferences - Look and Feel - Main Menu. There one System option is unchecked but I can't check it and apply. I am logged in as root. How do I bring it back? Please help. This is very irritating and weird. That guy doesn't even know what he has done so no use of asking him. :)

  • Is it safe to delete "Account Unknown" entries from Windows ACLs in a domain environment?

    - by Graeme Donaldson
    It's not uncommon to see entries in Windows ACLs (NTFS files/folders, registry, AD objects, etc.) with the name "Account Unknown (SID)". Obviously these are because of old AD users or groups which at some point had permissions manually configured on the relevant object and have since been deleted. Does anyone know if it is safe to remove these "Account Unknown" ACEs? My gut feeling is that it should be just fine, but I'm wondering if anyone has any past experiences where doing this has caused trouble? Normally I just ignore these, but the company I'm working at now seems to have an abnormal number of these, most likely due to past admins' inexperience with AD/Windows and assigning permissions to user accounts rather than groups in all sorts of weird places. FWIW, our environment is not complex, a single domain forest, 4 DCs in 3 sites, with all network connectivity and replication healthy, so I'm certain that these "Account Unknown" entries are really old accounts, and not just because of some failure to resolve the SID to a human-readable name.

  • Is there an application that can do a blue screen effect with a webcam?

    - by Axxmasterr
    Background: This is not the blue screen of death I am speaking of but the process called "Blue Screening" that takes and removes a particular colored background from an image so that it can be superimposed on some other video/still picture. If you have ever seen the weatherman stand in front of the map, then you have seen someone doing a blue screen technique. I would like to be able to capture video from my webcam, then send that video to a blue screen program which removes the white (or other color) from the background and then inserts a background of my own choosing. (think of the dead guy in freejack who was calling from all of the different places on earth) Then once the image is superimposed, I would like to pipe it into Skype for video conferencing. Anyone have a good way to do this?

  • Does an unmanaged 4/8-port GBit Ethernet switch with a GBIC port exist?

    - by Aaron Digulla
    I'm looking for a simple unmanaged switch with 4-8 GBit Ethernet ports and a fiber port (either as a GBIC slot or pre-installed with a 1000BASE-SX port). Does something like that exist? [EDIT] I want to connect to places in my home without drilling large holes though the floors. Therefore, I'm looking for a cheap way to connect two GBit switches via fiber. I tried with a media converter (GBit <- multimode fiber) but that costs about 50% throughput. So I was hoping that there is a cheap, small GBit switch which has a GBIC slot). All I found so far are very expensive managed switches with 12 or 24 ports for industry use.

  • Firefox Not responding - Windows 7

    - by Paul
    Have just upgraded from Vista to Win7 (32 bit). On vista Firefox worked great. I am using 3.5.6 version. 2GB RAM. In windows 7 however whenever i click on a link, field or tab within the browser or various other places within firefox 'Not Responding' flashes on the title bar. Most of the time i have to click 2 or 3 times to get any link or whatever to work which is very annoying. Any ideas? Can't find anything obvious on google but notice other people get Not Responding messages a lot with various apps. Chrome Plus seems to be fine.

  • How can I find a laptop if it has a different model name all over the world?

    - by Mike
    CONUNDRUM: A laptop review in the UK talks about how brilliant the "ASUS ABCDE 55" is, but in America, France, etc there is no such laptop name. In fact it's called "ASUS 12345 AB" - AAARRGH! QUESTION: Is there a way of finding out all the diverse names for the same laptop all over the world? Example: if Samsung create a R2D2500, then what is that spec laptop called in all the other countries (if they release it of course). Or if it's not released, what is their similar spec laptop called in the other countries? I understand that specs may be different, but if I read a review on my trusted UK website, but live in say Australia, I want to be able to find the name of the same laptop in Australia and then check out local places to buy it. So if anyone knows if there is a technique, specific website, or even how to use a company website to find out these annoying name changes I'd really appreciate it.

  • In Chrome, is there a way to search only within my bookmarked sites?

    - by McGirl
    I'm not trying to search for a bookmark - I'm trying to search for a term that may appear on one of my bookmarked sites. For instance, if I wanted to search on the term "Obama" and restrict my query to the New York Times web site, I know I could type this into the main URL/Search bar in Chrome: obama site:nytimes.com I'm wondering if there's a way to change that so that it's effectively: obama site:any one of the sites in my Chrome bookmark folder Thanks in advance for your help!

  • How do I troubleshoot computer dumps?

    - by KronoS
    Once I have a dump of a computer crash/freeze, what are some tools and steps to take in order to troubleshoot crash based off of the dump itself? I am looking for tools to isolate what processes or issues are causing the crash, and also good techniques in troubleshoot the actual dump itself. Once I've determined what the "troublesome" process has been, what do I do to troubleshoot the issue? For example if I determine process foo.exe or bar.dll etc, is the problematic file how do I determine what can be done?

  • How to prevent windows from being resized?

    - by endolith
    Adobe Audition is really stupid in that when you change the size of the window, and then change it back to the original size, all the frame positions are lost and you have to tediously reposition them by hand. I'd like to make it completely impossible to ever resize the window, just keep it maximized at all times. If I accidentally click "Restore" or drag the title bar, it should either ignore it, or move around the screen while staying the same size. Is there any way to do this?
