  • How do you protect your <appid>.appspot.com domain from DDOS attack?

    - by jacob
    If I want to use CloudFlare to help protect my GAE app via it's custom domain, I still am vulnerable to attacks directly on the .appspot.com domain. How do I mitigate that? I could force redirect appspot.com host requests, such as discussed here: http://stackoverflow.com/questions/1364733/block-requests-from-appspot-com-and-force-custom-domain-in-google-app-engine/ But I would still suffer the load of processing the redirect in my app. Are there any other solutions?

  • Vlan on astaro 120

    - by Crash893
    (I'm not 100% sure where networking/router questions go this is my best guess) I have a astaro (sophos) white UTM 120 router for work I also have about 11 Voip phones with an externaly hosted pbx (company name = pingtone) Is there any advantage to setting up the phones on a vlan vs making a qos rule that all traffic to my tftp server gets right of way? networking is still a little soft to me Thanks

  • what permissions are granted to a sql server database owner?

    - by Charles Hepner
    I have been trying to find out what permissions are granted to the owner of a database in SQL Server 2005 or higher. I have seen best practices questions like this one: What is the best practice for the database owner in SQL Server 2005? but I haven't been able to find anything specifically addressing what the purpose of having a database owner in SQL Server is and what permissions are granted as a result of making a given login a database owner. If the owner of the database is disabled, what would stop working?

  • Do busy smtp servers use long running tcp connections to exchange lot of mails?

    - by iamrohitbanga
    I had this idea from http://stackoverflow.com/questions/2813326/maximum-number-of-bytes-that-can-be-sent-on-a-tcp-connection is it possible that smtp servers like gmail and yahoo enter into some form of agreement to maintain a tcp connection between them so that lots of mails could be sent on the same tcp connection. it would be efficient as there would be heavy mail traffic between these mail servers.

  • Getting a list of packages installed on CentOS (by command line and on the web)

    - by sameold
    When installing CentOS (6.2), it installs a whole bunch of packages, but the installation is often very fast, it's hard to note the names of the packages. I have a couple of questions: 1) I'm guessing I could wait for the entire installation to complete and then query for the list of installed packages on the system. How do I do that? 2) Is there a printed list somewhere on the web, so I don't have to install the OS first just to get the list?

  • RSS Reader with inline image downloader for offline viewing

    - by Markii
    Guess the title kind of says it all, I know there have been a few of these questions before and I have tirelessly tried to do this research but have had very little luck. Essentially I love Google Reader and gears for offline viewing but more and more blogs are referring to diagrams and pictures in their articles and if I'm on a plane, I am not able to see any of these since they are not downloaded during offline mode. Any RSS readers out there that are?

  • Development stopped: Is truecrypt unsecure?

    - by Alex Mantel
    I was looking for truecrypt today and found this: http://truecrypt.sourceforge.net/ The page layout changed and claims "truecrypt is unsecure". Futher: "The development of TrueCrypt was ended in 5/2014 after Microsoft terminated support of Windows XP" My Questions: What are the risks for still using truecrypt? Will there be any fork of truecrypt? Is Windows "BitLocker" trustable? Is the reason why the development stopped reliable? Which independent alternatives are there for Linux, MacOS and Windows?

  • using git for media libraries

    - by mpapis
    Rationale: I want to manage libraries of media files (music, images) using git, there is git-annex but it requires haskel platform - but they do not play together well (also it's quite to big dependency for me). Question: Is there any other plugin with this functionality, or possibly would it be possible to write such plugin (resources?). Similar questions: Self-hosted, cross-platform repository for large files Using Git to Manage An iTunes Library?

  • Switching efficiently between windows, not apps, in OS X

    - by Vultan
    Previous questions have asked "how can I efficiently switch between windows, not applications, in OS X"? (Switching windows on OS X, Switch between windows on Mac OS X? and others). The most recommended suggestions seem to be: Use some combo of cmd-tab and cmd-~. Use Expose, and possibly Spaces Use Witch I spent the money on Witch, and have been using it for a few weeks; it's ok, but it is sometimes slow to respond, sometimes buggy on window order, crashes my system if I disable and re-enable it too many times, and doesn't work properly with X11 apps. The built-in cmd-tab and cmd-~ are ok, but still bring an entire application to the forefront. I find a very common workflow I use is to bounce back and forth between two windows (for example, a browser window and a Thunderbird email in progress), when both apps (the browser and email software) have multiple windows open. I can use Cmd-Tab to get back and forth between apps, but whenever I switch to an app, ALL windows from that app pop up. That suddenly fills my screen with irrelevant data and windows, and often drops those other windows in front of the single window from the other app that I was using and would conveniently like to keep viewing even though it isn't in focus. Expose seems to be the preferred "OS X natural way," but I can't seem to get myself to use it efficiently. I hit F9, and see 10 windows; I then need to squint, try to find the window I want, then use the mouse or the cursor keys to navigate to the one I want. Given the number of power users who say they use Expose, I must be missing the boat here. My goal is not to make this a repeat of previous questions. I'm not asking "what are my alternatives?" (unless I've missed one above!) Rather, I'm asking: what are you, OS X power users, actually doing to handle the use case I described above? Another common use case for me is having multiple Excel spreadsheets open and multiple browser windows open, and I'm rapidly switching back and forth between one spreadsheet in particular and one browser window. Every time I Cmd-Tab, all spreadsheets or all browser windows appear: I don't want to see the ones I'm not working with, and they tend to hide the windows from the alternative app that I don't have in focus but I'd like to at least eyeball. Can you describe what your workflow is like, and how you rapidly and thoughtlessly switch between windows from apps that have multiple windows open?

  • Kill PHP process when connection is closed

    - by user838437
    I've posted the following question to SO, but thought there might be a server based solution. http://stackoverflow.com/questions/9053964/php-script-with-sleep-does-not-exit-on-connection-close I'm running an Ubuntu VPS to run this script, and I'm trying to get the script to die when the user closes the window/tab of his browser. There are several PHP based functions to see if the connection is still open, but none works (trust me, tested them all). Any creative ideas on how I can do this through the server maybe?

  • FTP script needs blank line

    - by Ones and Zeroes
    I am trying to determine the reason for some FTP servers requiring a blank line in the script as follows: open server.com username ftp_commands bye Refer to blank line required after username credentials. Example from: FTP from batch file another reference to the same: http://newsgroups.derkeiler.com/Archive/Comp/comp.sys.ibm.as400.misc/2008-05/msg00227.html Also discussed here: archive.midrange.com/midrange-l/200601/msg00048.html "The behavior I'm observing is the same as if I didn't specify the password to login." with an answer referring to our same fix... archive.midrange.com/midrange-l/200601/msg00053.html and archive.midrange.com/midrange-l/200601/msg00065.html Note: It is my experience that FTP questions attract uncouth responses. Admittedly FTP is outdated, but many clients still have legacy systems, which they cannot upgrade or replace. The reason thereof should not be discussed here. The intention of this question is to invite a positive response. Please do not respond if you disagree with the above. If you have never encountered this same issue, please do not respond. I suspect this may be limited to FTP scripts executed from Windows machines, but have been told that this happens often and with many different servers. My specific interest is to understand what may cause this as I have a real world example of a production system suddenly requiring this as a workaround fix, after running for many years without issue. The server belongs to a third party who claims no change on their end. Server details unknown and cannot be determined. Any help or encouragement from someone who has come across the same, would be appreciated. ps. Sorry for the many words and references to painful responses, but I have asked similar questions on serverfault and elsewhere and unfortunately got back kneejerk responses to FTP and respondents debating the validity of the question. I would truly not ask, or re-post this question online if I had a better understanding of the issue. I know of people who have seen this issue, but don't know what causes it. I am wary that this question would again turn into another irrelevant discussion. Please, I ask very nicely: Please do not respond if you have not encountered a similar issue. FURTHER EDIT: Please do not suggest changing the product. The problem is not the blank line requirement. We know this fixes the issue. The problem is not being able to explain the reason for the blank line in the first place. Slight difference, but a critical point to note wrt the answering of this question.

  • How to see all nics in Solaris 8/9

    - by help_me
    I have a questions regarding how to see all NICS in the solaris 8/9 SPARC boxes. Even if they are active/inactive. dladm show-link command does not work. cat /etc/path_to_inst could but it's hard to make out the NICS. Also when a cable is disconnected from the NIC ifconfig -a still shows the NIC as "UP/RUNNING" without looking at the system message, is there a way to know that the NIC is unplugged? Thank you!

  • Add send/receive to Outlook systray icon?

    - by Hannele
    Is it possible to add a send/receive action to the Outlook 2007 system tray right-click context menu? It's a little annoying to have to open the whole interface just to run this simple action manually. I have searched for an answer, but could only find two other unanswered questions. If there's no particular answer as of yet, would it make more sense to explore making a plug-in like this one to keep running in the systray when closed, or to look for a registry hack, or something else entirely?
