• Is it possible to "stealth" dual boot a machine?

  - by BrianH

  I have a loaner laptop that has MS Windows with locked down permissions. It works okay for what I need to do, but I started wondering if there was a way to install a separate Windows OS on a separate hard drive to do what I want to do on it. Virtual I wish I could use VirtualBox or VMWare, but that is not an option (I even tried VBox portable). External Drive My next trial was see if it was possible to install Windows on an external drive, and then plug that drive in and boot from it whenever I wanted my own OS. After a few Google searches, I see that is not really a possibility. Swap Primary Drive Another option, would be to get a second internal hard drive, take the existing HD out, and install a new Windows OS on the secondary HD. This would mean swapping the internal hard drive each time I want to switch OSs - doable, but not very convenient. Dual Boot The laptop has an expansion slot where a second hard drive can be plugged in quickly. I thought about Dual booting, but I don't want to mess with the MBR on the primary hard drive. When I have to give the laptop back, I don't want a dual-boot screen to popup. Summary Is there a way to have 2 hard-drives on a machine, each with it's own OS, and maybe use BIOS settings to have only 1 hard drive active at a time? That way both hard drives could be physically connected, but only one would actually be active at a time. I basically want a second OS that does not (can not) affect the existing OS in any way, and can be removed at any time without affecting the existing OS. The secondary OS does not need any of the files on the main hard drive - it's basically like having 2 separate computers using the same hard ware... Is this possible, or would it be easier just to go out and buy a different laptop? Thanks in advance! EDIT I just discovered that my BIOS allows me to pick (at startup) which hard drive I want to boot from. I poked around in the BIOS and there is not a place to disable certain devices, like the primary hard drive. My only concern about plugging in a second hard drive and installing Windows to the second hard drive is that it will mess with the primary hard drive, or add a bootloader screen to pick which windows install to use. My thought would be to physically unplug the primary, plug in the secondary and install windows to the secondary. After the install is working properly, I can plug the primary back in and use the BIOS feature to determine which drive to boot to. Is there any way after I have 2 separate installs on 2 separate hard drives that one of the installs could mess with the MBR on the other drive?

• Do these 3 crashes have something in common?

  - by David U

  I'm running OS X 10.6.8 on a Mac Mini. I tried to install 3 applications today and all 3 installations failed. I am wondering if the failures have something in common. First I installed GraphViz. The installation succeeded, but when I try to open any .dot file, I get a dialog that says GraphViz has quit unexpectedly. Next I installed Doxygen. It installed, but when I try to launch it I get a dialog that tells me Doxywizard quit unexpectedly. After some googling I thought perhaps my system lacked QT, and that was the problem. I downloaded the Qt 4.8.4 packages and installed them. But when I try to launch qtdemo.app, or any of the other apps that came with the qt installation, I get a dialog that says I can't open the app because it's not supported on this type of Mac. I have crash logs from GraphViz and Doxygen. They're long and I think it unnecessary to post them unless they would help someone determine my problem.

• What issues ensue from having multiple versions of Office installed?

  - by Michael Sorens

  My ultimate question is embodied in the title but I thought it might be helpful to others if I detail what instigated my inquiry and my examination of the problem. To me, the first rule of software updates is Primum non nocere -- first, do no harm. So with my Windows 7 system containing both Office 2003 and Office 2010 I blithely proceeded to install this month's updates from Microsoft, containing updates for both versions of Office. While Microsoft officially does not recommend running multiple versions (see, for example, Running Multiple Versions of Microsoft Excel it is possible; I have had two versions installed for a year or more and have never run into an issue before. One thing that is always mentioned is installation order, i.e., the one you want to open files by default should be installed last. I wanted 2010 as my default so I had indeed installed 2003 first then, years later, 2010. So with this round of Windows updates, either it installed patches to 2010 before 2003, knocking out the file association, or the 2003 patch was more comprehensive, in the sense of touching the file association while the 2010 did not. In any case, after updates, double-clicking a .xls file opened 2003 rather than 2010. Web search indicated either: Use the file associations control panel to re-associate .xls files with the correct version of excel. I looked at this first, but it showed what seemed to be an unversioned "Excel" associated with .xls files so I did not check further. (This turned out to be an error on my part; more later.) Re-install versions in the desired order; I find this unreasonable. Run the repair option of the Office installer on the desired version; still seems more work than one should need. Run excel from the command line with "/regserver" on the one to be the default and "/unregserver" on the other. Good idea, but further search indicated that neither 2007 nor 2010 support "/regserver" contrary to some posts (e.g. Default Program With Multiple Versions Installed). Since this was a Windows Update issue and Microsoft provides free support for such, I inquired there as well, but succeeded only in getting the suggestion to uninstall all other versions, period; not acceptable to me. What worked for me was going back to the file associations control panel and manually selected the Office 2010 version of Excel. While it appeared no different in the control panel, it did fix the double-click issue. So if all it takes is this simple fix after an update, I can live with that. What I am wondering is: Has anyone seen any other problems related to having multiple versions of Office installed?

• Windows 7 Home hangs at "Welcome" screen

  - by White Phoenix

  I'm asking on behalf of a friend who's currently having problems with his machine. Windows 7 Home 32-bit. He's too far away for me to help by going over to his house - I'm helping him over the Internet. This is his current machine: http://www.newegg.com/Product/Product.aspx?Item=N82E16883227134 The only two changes he made to that machine is to swap out the gfx card for a EVGA GTX 460 and the PSU for a Corsair TX650. Here's what happened: He was playing a computer game (fairly CPU/GPU intensive) and had some music going in the background in foobar while playing. Suddenly, he notices the music stopped playing, so he switches to foobar to try to close it, but it freezes up (window won't respond). So he figures it's just foobar having a bad day and force quits that program. Suddenly, his game won't respond, so he force quits that, then the entire computer just went to crap at that point, so he hits the restart button on his machine. Computer POSTS fine, but now he gets stuck at the Windows "welcome" screen (his account is set to auto-login). HD activity light is solid yellow but he doesn't hear HDD activity. He tried booting into Safe Mode - gets stuck at the "welcome screen". Tried a STartup Repair within Windows 7, it found a few problems, but still gets stuck at welcome. I advised him to boot off the DVD - sfc /scannow found nothing (couldn't use the regular /scannow option; says there's a repair pending, had to use use offbootdir/offwindir command switches). Ran startup repair 3 times - found nothing. My friend runs virus/malware scans on a regular basis, so he's fairly sure it's not that either. Right now I'm having my friend run chkdsk /R on the computer while in this Startup Recovery mode - so far it's caught a few bad sectors. However at this point I'm kinda wondering which way to go if chkdsk doesn't fix it. Quick Google search said someone had success by booting Windows with bootlogging on - some others have success with running the aforemented chkdsk, etc. The fact that Windows cannot even boot into Safe Mode concerns me. While we're waiting for chkdsk /R to finish, are there any other options I can give my friend short of reinstalling Windows 7? He has his data on a separate partition so that's not a major problem (though it'll be an annoyance for him). I suspect his hard drive may be having some issues, but my main concern is getting him back up and running before we start diagnosing the hard drive (I may have him run some sort of SMART test utility later).

• Tool or script to detect moved or renamed files on Linux prior to a backup

  - by Pharaun

  Basically I am searching to see if there exists a tool or script that can detect moved or renamed files so that I can get a list of renamed/moved files and apply the same operation on the other end of the network to conserve on bandwidth. Basically disk storage is cheap but bandwidth isn't, and the problem is that the files often will be reorganized or moved around into a better directory structure thus when you use rsync to do the backup, rsync won't notice that its a renamed or moved file and re-transmission it over the network all over again despite having the same file on the other end. So I am wondering if there exists a script or tool that can record where all the files are and their names, then just prior to a backup, it would rescan and detect moved or renamed files, then I can take that list and re-apply the move/rename operation on the other side. Here's a list of the "general" features of the files: Large unchanging files They can be renamed or moved around [Edit:] These all are good answers, and what I end up doing in the end was looking at all of the answers and will be writing some code to deal with this. Basically what I am thinking/working on now is: Using something like AIDE for the "initial" scan and enable me to keep checksums on the files because they are supposed to never change, so it would aid on detecting corruption. Creating an inotify daemon that would monitor these files/directory and recording any changes relating to renames & moving the files around to a log file. There are some edge cases where inotify might fail to record that something happened to the file system, thus there is a final step of using find to search the file system for files that has a change time latter than the last backup. This has several benefits: Checksums/etc from AIDE to be able to check/make sure that some media did not get corrupt Inotify keeps resource usage low and no need to re-scan the filesystem over and over No need to patch rsync; If I have to patch things I can, but I would prefer to avoid patching things to keep the burden lower, (IE don't need to re-patch everytime there is an update). I've used Unison before and its really nice, however I could've sworn that Unison does keep copies around on the filesystem and that its "archive" files can grow to be rather large?

• How to setup GIT repo on server with need for working dir (non- bare)

  - by OrangeTux

  I want to have configurate a GIT repo for a website. Multiple users will have a clone of the repo on their local machine and on the end of each day they push their work to the server. I can setup a bare repo, but I want a working dir/non-bare repository. The idea is that the working dir of the repository will the root folder for the website. At the end of each day all changes will be visible directly. But I can't find a way to do this. Initializing the server repo with git init gives the following error when a client is trying to push some files: git push origin master [email protected]'s password: Counting objects: 3, done. Writing objects: 100% (3/3), 227 bytes, done. Total 3 (delta 0), reused 0 (delta 0) remote: error: refusing to update checked out branch: refs/heads/master remote: error: By default, updating the current branch in a non-bare repository remote: error: is denied, because it will make the index and work tree inconsistent remote: error: with what you pushed, and will require 'git reset --hard' to match remote: error: the work tree to HEAD. remote: error: remote: error: You can set 'receive.denyCurrentBranch' configuration variable to remote: error: 'ignore' or 'warn' in the remote repository to allow pushing into remote: error: its current branch; however, this is not recommended unless you remote: error: arranged to update its work tree to match what you pushed in some remote: error: other way. remote: error: remote: error: To squelch this message and still keep the default behaviour, set remote: error: 'receive.denyCurrentBranch' configuration variable to 'refuse'. To ssh://[email protected]/home/orangetux/www/ ! [remote rejected] master -> master (branch is currently checked out) error: failed to push some refs to 'ssh://[email protected]/home/orangetux/www/' So I'm wondering if this the right way to setup a GIT repo for a website? If so, how do I have to do this? If not, what is a better way to setup a GIT repo for the development of a website? EDIT you can't push to a non-bare repository Oke, clear. But whats the way to solve my problem? Create a bare repository on the server and have a clone of this repo on the same server in the htdocs folder? This looks a bit clumsy to me. To see the result of a commit I've to clone the repository each time.

• Clamdscan scans file in 0 seconds

• Triple (3) Monitors under Linux

  - by widgisoft

  I have a 3 monitor setup (each 1680x1050) via an Nvidia NVS440 (2 GPUs, 2 outputs per GPU totalling 4 outputs); this works fine under Windows XP,7 but caused considerable headaches under Linux (Ubuntu 9.04). I had previously used an XFX 9600GT and the onboard XFX 9300GS to produce the same result but the card was noisy and power hungry and I was hoping that there was some magical switch in the NVS4400 that got rid of this annoying problem - turns out the NVS440 is just 2 cards on one physical PCB :-p (I searched the net high and low for people using this card under Linux but found nothing, if anything the card uses less power and is fan less so I was to benefit from it either way) Anyway, using either set up there were 5 solutions available: Have 3 separate X instances, all un joined Have 3 separate X instances, adjoined by Xinerama Have 2 separate X instances - One using twin-view, both adjoined by Xinerama Have 2 separate X instances - One using twin-view but no Xinerama Have a single Twin-view setup and leave the 3rd screen unplugged :-p The 4rd option, using 2 separate X instances and twinview (but no xinerama) was the best balance in terms of performance and usability but caused 2 really annoying issues You couldn't control (without altering the shortcuts) which screen an application opened onto - and once it was opened you couldn't move it to another screen without opening up terminal and forcing it to move Nvidia's overriding or falsifying of Xinerama breaks and the 2 screens joined by Twin view behave like a single huge screen causing popups to open in the middle of both screens and maximising of windows stretches to the width of the first 2 screens Firefox can only run one instance as the same user so having multiple firefox windows requires at least 2 users The second option "feels" like the right option, but OpenGL is basically disabled and playing any sort of game or even running anything graphical causes a huge performance drop and instability - even trying to run a basic emulator for gba or gens just causes the system to fall over. It works just enough to stare at your desktop and do nothing but as soon as you start doing some work - opening windows, dragging things around - running multiple copies of firefox it just really feels slow. The last open, only going dual screen works perfectly and everything performs as required, full GPU acceleration - two logical screen spaces - perfect, just make it work across GPUs like windows! :-p Anyway, I know RandR was supposed to pick up the slack when it would introduced GPU objects of sorts to allow multiple GPUs to be stitched together to create one huge desktop at a much deeper layer than Xinerama. I was wondering if this has now been fixed (I noticed X server 1.7 is out) and whether anyone has got it running successfully? Again, my requirements are: One huge desktop to drag any window across Maximising of windows to each screen (as XP does) Running fullscreen apps on the primary screen and disabling the mouse from moving onto the others or on all 3 stretched Finally as a side note; I am aware of the Matrox triple (and dual) head splitter but even the price they go for on eBay is more than I can afford atm, my argument: I shouldn't have to buy extra hardware to get something to work on Linux when it's something that's existed in the windows world for a long time (can you tell I don't get on with X :-p); If I had the cash I'd have bought the latest version of this box already (the new version finally supports large resolutions as the displays I have 1680x1050 each).

• APC PHP cache size does not exceed 32MB, even though settings allow for more

  - by hardy101

  I am setting up APC (v 3.1.9) on a high-traffic WordPress installation on CentOS 6.0 64 bit. I have figured out many of the quirks with APC, but something is still not quite right. No matter what settings I change, APC never actually caches more than 32MB. I'm trying to bump it up to 256 MB. 32MB is a default amount for apc.shm_size, so I am wondering if it's stuck there somehow. I have run the following echo '2147483648' > /proc/sys/kernel/shmmax to increase my system's shared memory to 2G (half of my 4G box). Then ran ipcs -lm which returns ------ Shared Memory Limits -------- max number of segments = 4096 max seg size (kbytes) = 2097152 max total shared memory (kbytes) = 8388608 min seg size (bytes) = 1 Also made a change in /etc/sysctl.conf then ran sysctl -p to make the settings stick on the server. Rebooted, too, for good measure.

• A proper way to create non-interactive accounts?

  - by AndreyT

  In order to use password-protected file sharing in a basic home network I want to create a number of non-interactive user accounts on a Windows 8 Pro machine in addition to the existing set of interactive accounts. The users that corresponds to those extra accounts will not use this machine interactively, so I don't want their accounts to be available for logon and I don't want their names to appear on welcome screen. In older versions of Windows Pro (up to Windows 7) I did this by first creating the accounts as members of "Users" group, and then including them into "Deny logon locally" list in Local Security Policy settings. This always had the desired effect. However, my question is whether this is the right/best way to do it. The reason I'm asking is that even though this method works in Windows 8 Pro as well, it has one little quirk: interactive users from "User" group are still able to see these extra user names when they go to the Metro screen and hit their own user name in the top-right corner (i.e. open "Sign out/Lock" menu). The command list that drops out contains "Sign out" and "Lock" commands as well as the names of other users (for "switch user" functionality). For some reason that list includes the extra users from "Deny logon locally" list. It is interesting to note that this happens when the current user belongs to "Users" group, but it does not happen when the current user is from "Administrators". For example, let's say I have three accounts on the machine: "Administrator" (from "Administrators", can logon locally), "A" (from "Users", can logon locally), "B" (from "Users", denied logon locally). When "Administrator" is logged in, he can only see user "A" listed in his Metro "Sign out/Lock" menu, i.e. all works as it should. But when user "A" is logged in, he can see both "Administrator" and user "B" in his "Sign out/Lock" menu. Expectedly, in the above example trying to switch from user "A" to user "B" by hitting "B" in the menu does not work: Windows jumps to welcome screen that lists only "Administrator" and "A". Anyway, on the surface this appears to be an interface-level bug in Windows 8. However, I'm wondering if going through "Deny logon locally" setting is the right way to do it in Windows 8. Is there any other way to create a hidden non-interactive user account?

• Echo 404 directly from nginx to improve performance

  - by user64204

  I am in charge of production servers serving static content for a website. Those servers are constantly being crawled by bots looking for potential exploits (which isn't that much of a problem security-wise because no application can be reached behind the web server) but generates thousands of 404 per day, sometimes per hour. I am looking into ways of blocking those requests but it's tricky (you want to make sure you don't block legitimate traffic and these bots are becoming more and more clever at looking like they're legit) and is going to take me a while to find an acceptable solution. In the meantime I would like to reduce the performance impact of serving those 404 pages. Indeed we're using nginx which by default is configured to serve it's 404 page from the disk (This can be changed using the error_page directive but in the end the 404 will either have to be served from disk or from another external source (e.g. upstream application which would be worst)) which isn't ideal. I ran a test with ab on my local machine with a basic configuration: in one case I echo a message directly from nginx so the disk isn't touched at all, in the other case I hit a missing page and nginx serves its 404 from disk. server { # [...] the default nginx stuff location / { } location /this_page_exists { echo "this page was found"; } } Here are the test results (my laptop has Intel(R) Core(TM) i7-2670QM + SSD in case you're wondering why they are so high): $ ab -n 500000 -c 1000 http://localhost/this_page_exists Requests per second: 25609.16 [#/sec] (mean) $ ab -n 500000 -c 1000 http://localhost/this_page_doesnt_exists Requests per second: 22905.72 [#/sec] (mean) As you can see, returning a value with echo is 11% ((25609-22905)÷22905×100) faster than serving the 404 page from disk. Accordingly I would like to echo a simple 404 Page not Found string from nginx. I tried many things so far but they all failed, essentially the idea was this: location / { try_files $uri @not_found; } location @not_found { echo "404 - Page not found"; } The problem is that as soon as the echo directive is used, the http response code is set to 200. I tried changing that by doing error_page 200 = 400 but that breaks the configuration. How can I serve a 404 page directly from nginx? (without hacking the source which may be might next step)

• D-Link DIR-300 slows down / loses network

  - by basic6

  there are 2 buildings (A and B). In bldg A is an open WLAN (which I'm allowed to use btw). In bldg B is a computer that I want to connect to that network. So I flashed an old D-Link DIR-300 AP with DD-WRT, mounted it to the wall (bldg B) near a window, attached a 13 dBi directional antenna (pointing to bldg A) and configured it as AP client in that wireless network. Then there's another AP, connected to the D-Link AP, acting as standard access point, which the computer is connected to. That's basically working so far, but: Every now and then the connection is lost. Not the connection between the computer and the D-Link (I can access the DD-WRT admin page normally) or the connection between the D-Link and the WLAN (in Status - Wireless it says it's still connected to the network), but when I want to access a web page (which only works if I'm connected to the wireless network from bldg A), my Firefox keeps "Looking for" (name resolution) without finding anything. When I reset the D-Link (power off, power on) in this situation, after some moments, everything's working fine again (Internet access). I've no idea why this is happening, but usually it's at most every few weeks (most times when nobody was using the computer, so no traffic). Compared to the connection speed when I connect directly to the WLAN in bldg A (Laptop), the speed in bldg B is rather slow, but I have the impression that this difference is worse in the last few days. A few minutes ago, I got 582 KB/s down and 911 KB/s up in bldg A (directly/laptop) and 84 KB/s down and 9 KB/s up in bldg B. The speed in bldg B used to be way higher (I remember 200 KB/s up) while the actual network speed in bldg A was lower than it is now (close to those 200). I'm aware that the wireless connection between those buildings should slow things down, but I'm wondering why this difference has become that extreme. Thanks for any tips... Update: I currently want to upload a large file (1.5 GB) via FTP (FileZilla). Since that caused the D-Link to disconnect (as described in first post), I took my laptop to bldg A, connected directly to the original WLAN (bypassing my D-Link) and tried the same upload. Guess what - same issue: At some point the connection is dead (at this point I would have reset my D-Link if I was connected to it). Just as the D-Link, my laptop is still connected, but not even name resolution is working ("Looking for..." in Firefox). After reconnecting, it's working again. Maybe my D-Link isn't the problem at all...

• Have a server, need to figure out a method of backup

  - by PolishHurricane

  My company has an older Dell 2650 server running ArchLinux x64: http://www.dell.com/downloads/global/products/pedge/en/2650_specs.pdf (2 x 2.4GHz Intel Xeon w/around 3287 RAM according to "free -m") We use it to host our internal company site and to post some information from our orders to and we'd like the ability to keep it up as much as possible. What we require: - It needs to always be functional from 8am to 4pm for our data entry person to use it and others to do other things required on it. - If it goes down, we need a quick way to get the machine running again. - If it goes down, we would like to have the data backed up. Some of the major problems include: - The servers old and it may have memory issues - We don't know when one of the hard drives could fail - Our power goes out here once in a while We have a battery backup, but that's pretty much it and it's not for long term. If the server does go down, we have another system in place to store order information that comes in while it's down and repost it when it's back, but we need it up during the day. So we're wondering, what should we get for options? These are the things we thought of, sort of: Setup RAID 1, but that would involve wiping everything right? If we do that, how would we transfer the data over without messing up the server? We could buy an extra server or 2 off eBay for $100, the same model, is that practical or should we get something else? Should we buy a PC or another better server and host off that because it is if anything easier to exchange parts? Should we keep extra parts handy incase it implodes? Should we buy/use backup software? We hear drobo's are cool, but suck. Perhaps there is a software solution to this problem that backs up to another machine or gets us up and running again quickly. Also, if we are to purchase hardware, what is decent? Does anybody know of one for ArchLinux/Linux? We both know a ton about computers but we're kind of unsure what step to take with this, especially with this type of server. Thanks

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

  - by user69508

  (Please forgive if this is posted in an incorrect forum. We didn’t know exactly where to post it.) We have an ASP.NET Web API single page application - a browser-based app running in IIS to serve up HTML5/CSS3/JavaScript, which talks to the ASP.NET Web API endpoint only to access a database and transfer JSON data. Everything is working great in our development environment - that is, we have one Visual Studio solution with an ASP.NET Web API project and two class library projects for data access. While development and testing on development boxes, using IIS Express to a localhost:port to run the site and access the Web API, everything is fine. Now we need to move it to a production environment (and we’re having problems - or just not understanding what needs to be done). The production environment is all internal (nothing will be exposed on the public Internet). There are two domains. One domain, the corporate domain, is where all users login normally. The other domain, the process domain, contains the SQL Server instance that our app and Web API will need 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. So, I guess what they want 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’re developers and don’t really understand all the networking aspects, so we’re wondering 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 (HTML5/CSS3/JavaScript/images/etc.) is on the IIS server in the DMZ, while the Web API gets installed on the server in the process domain? Or, 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?)? I’m sure there are other questions, but we’ll start with these. Thanks!!! (Note: the servers are Win2k8 R2, SQL Server 2k8 R2, and IIS 7.5.)

• Display is slightly blurry on (native) 1920x1080 resolution

  - by Martin Tuskevicius

  I have a computer monitor that is approximately 23" in size. Its native resolution is 1920x1080, and Windows 7 will not allow it to be any higher. However, I cannot make the resolution a little lower as well. When I right-click on my desktop and select 'Screen resolution,' the vertical slider has only two options: 1920x1080 and 1280x720. There are no real problems that I am having besides the fact that the image is slightly blurry. I can easily make things out and see them, but I definitely feel that the image is not as clear as it could be. My graphics card is ATI Radeon HD 5450 and it has the latest graphics drivers installed. I've tried playing around with the AMD VISION Engine Control Center to see if I can change an option to make the image clearer, but I had no luck. I did find one odd thing, though. When I lowered the refresh rate from 60Hz to 50Hz, the image kind of "zoomed in" but it also became perfectly clear like I would expect it to look. The problem is that when I use 50Hz, the image zooms in a little on the center and I lose maybe an inch and a half of the screen (I do not see the bar at the top of applications, I do not see the Windows taskbar thing, etc). I figured if I could somehow zoom in so that the entire image fills the screen (not the slightly cropped version) then I would have the perfectly crisp image of 50Hz, and also the uncropped image of 60Hz. However, upon zooming in, the image began to look blurry again just like it did with 60Hz. So I am at a loss here. I do not know how to make the image look as clear as it should. I have the latest drivers (I updated them today) and I know that my monitor supports the resolution that I am trying to use. Has anybody experienced something like this before? I'd really appreciate any input - thanks! Update: I have figured out how to make the display look crisp! I set it to the 50Hz option, and then I changed the scaling through the monitor itself, rather than software. Now, however, I am finding that games look pretty bad because since it is clear, the lower quality really becomes apparent. I cannot run new games at 1080p, so I run them at the lowest resolution possible (1280x720, since it is the only other option offered, as I have mentioned). So I am wondering, is there a way to have Windows display more resolution options?

• What is the difference between running a Windows service vs. running through shell?

  - by Zack

  I am trying to troubleshoot an issue on a Windows 2008 server where running attempting to connect to a "Timberline Data Source" ODBC driver crashes if the call is in a "service" context, but succeeds if the call is initiated manually in a Remote Desktop session. I have set the service to run as my user. I'm wondering if, all else being equal (user, machine, etc), are there any fundamental security/environment differences between running a process as a service vs manually? --- Implementation Details --- In case it is helpful for anyone, I had a system that started as an attempt to connect to a Timberline Database using ODBC and a Python CGI script called via IIS 7. The script itself works fine, however, as soon as I attempt to perform the ODBC connect function, the script crashes without throwing an exception. The script was able to connect fine when executed via command line. The same thing happened when using a C#/.net service, attempting to run via Apache, Windows Scheduler or even a 3rd party scheduling tool. With the last option (the 3rd party scheduling tool, pycron) I set the service up log in as my user and had the same issue (I confirmed via Task Manager that the process running user was, in fact, me). It just doesn't make sense to me why a service, which should be running as my user, appears to still be operating in a different security context or environment. Also, if it's important, the Timberline database is referenced by computer name on the network ("\\timberline-server\Timberline Office\Accounts\AT" or something to that effect) I also realized that, as Joel pointed out, the server DOES have a mapped drive ("Y:" which is mapped to "\\timberline-server\Timberline Office") The DSN is set up at the "System DSN" level which, according to the ODBC Administration Tool, means that the DSN is available to users and services Since I'm not allowed to answer this question yet, I'll post the solution that I arrived on: As Joel Coel mentioned, there actually was a mapped drive scenario. I didn't realize this because the DSN specified a path using UNC. However, it seems as though the actual Timberline Driver referred to a mapped drive. Since services don't start with the mapped drive, I was forced to add the drive mapping code into my service. Since it was written in python, I used code from a Stackoverflow answer that was able to map the drive on the fly.

• Local dns for testing websites using mobile devices

  - by Morpheu5

  Hi. I have no idea where to start from so sorry in advance if this topic has already been discussed. I usually develop web sites using my laptop as a development server, and recently I needed to test a web site using various mobile devices that can connect via wifi. Having no real AP, I set up a ad-hoc network using my laptop's wireless card and the devices can correctly browse the Internet and access the laptop's web server. The setup is as follows: subnet: 192.168.1.0/24 gateway to the Internet (wired adsl router/modem): 192.168.1.1 laptop: 192.168.1.64 (eth0, wired if connected to the gateway) and 192.168.1.32 (eth1, wifi if somewhat bridged to eth0) mobile devices (same for all, I only use one of them at any time for simplicity): 192.168.1.11 with default gw 192.168.1.1 Now, if I open either 192.168.1.32 or 192.168.1.64 from the mobile devices, I correctly get the default host of my Apache configuration. However I usually work with virtual hosts for many practical reasons, one of which being Drupal's peculiar implementation of multi-sites. For those who don't know how this works, Drupal takes the request's hostname and searches into its sites/ subdirectories for an appropriate configuration file. So, for example, suppose I request www.example.com, then Drupal would search for a config file in the following directories: sites/www.example.com/ sites/example.com/ sites/com/ sites/default/ So I decided to adopt the following style of virtual hosts: if the website I'm working on will be accessible using www.example.com I set up a sites/www.example.com/ directory and create a virtual host for local.www.example.com so Drupal have no trouble finding it. I've been told this is suboptimal from a dns point of view since I'd have to create an authoritative entry for example.com and turn Bind on only when I'm supposed to access the local copy, which is weird. However, if this is the only path I can follow, I still have some problems with Bind's configuration, as I couldn't find any guide that tells me in a clear, noob-friendly way, how to set up such an entry. On the other hand, I was wondering if I could set up an authoritative entry for local, so I could access www.example.com.local and tell in some way (which I don't even know if this is possible) Apache to put www.example.com instead of www.example.com.local in the relevant environment variable. Anyway, I have a last problem, sort of: when I launch Bind in debug mode with high verbosity, and make 192.168.1.32 as the primary dns for the devices, the output doesn't say anything about requests being made from the devices to Bind, so I'm not even sure it comes into play. As you can see, I'm a complete noob at these matters, but I'm eager to learn, so any help/pointer will be appreciated.

• OpenVPN Chaining

  - by noderunner

  I'm trying to set up an OpenVPN "chain", similar to what is described here. I have two separate networks, A and B. Each network has an OpenVPN server using a standard "road warrior" or "client/server" approach. A client can connect to either one for access to the hosts/services on that respective network. But server A and B are also connected to each other. The servers on each network have a "site-to-site" connection between the two. What I'm trying to accomplish, is the ability to connect to network A as a client, and then make connections with hosts on network B. I'm using tun/routing for all of the VPN connections. The "chain" looks something like this: [Client] --- [Server A] --- [Server A] --- [Server B] --- [Server B] --- [Host B] (tun0) (tun0) (tun1) (tun0) (eth0) (eth0) The whole idea is that server A should route traffic destined to network B through the "site-to-site" VPN set up on tun1 when a client from tun0 tries to connect. I did this simply by setting up two connection profiles on server A. One profile is a standard server config running on tun0, defining a virtual client network, IP address pool, pushing routes, etc. The other is a client connection to Server B running on tun1. With ip_forwarding enabled, I then simply added a "push route" to the clients advertising a route to network B. On server A, this seems to work when I look at tcpdump output. If I connect as a client, and then ping a host on network B, I can see the traffic getting passed from tun0 to tun1 on Server A: tcpdump -nSi tun1 icmp The weird thing is that I don't see Server B receiving that traffic through the tunnel. It's as if Server A is sending it through the site-to-site connection like it should, but server B is completely ignoring it. When I look for the traffic on Server B, it simply isn't there. A ping from Server A -- Host B works fine. But a ping from a client connected to Server A to host B does not. I'm wondering if Server B is ignoring the traffic because the source IP does not match the client IP pool that it hands out to clients? Does anyone know if I need to do something on Server B in order for it to see the traffic? This is a complicated problem to explain, so thanks if you stuck with me this far.

• Nginx SSL redirect for one specific page only

  - by jjiceman

  I read and followed this question in order to configure nginx to force SSL for one page (admin.php for XenForo), and it is working well for a few of the site administrators but is not for myself. I was wondering if anyone has any advice on how to improve this configuration: ... ssl_certificate example.net.crt; ssl_certificate_key example.key; server { listen 80 default; listen 443 ssl; server_name www.example.net example.net; access_log /srv/www/example.net/logs/access.log; error_log /srv/www/example.net/logs/error.log; root /srv/www/example.net/public_html; index index.php index.html; location / { if ( $scheme = https ){ rewrite ^ http://example.net$request_uri? permanent; } try_files $uri $uri/ /index.php?$uri&$args; index index.php index.html; } location ^~ /admin.php { if ( $scheme = http ) { rewrite ^ https://example.net$request_uri? permanent; } try_files $uri /index.php; include fastcgi_params; fastcgi_pass 127.0.0.1:9000; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param HTTPS on; } location ~ \.php$ { try_files $uri /index.php; include fastcgi_params; fastcgi_pass 127.0.0.1:9000; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param HTTPS off; } } ... It seems that the extra information in the location ^~ /admin.php block is unecessary, does anyone know of an easy way to avoid duplicate code? Without it it skips the php block and just returns the php files. Currently it applies https correctly in Firefox when I navigate to admin.php. In Chrome, it downloads the admin.php page. When returning to the non-https website in Firefox, it does not correctly return to http but stays as SSL. Like I said earlier, this only happens for me, the other admins can go back and forth without a problem. Is this an issue on my end that I can fix? And does anyone know of any ways I could reduce duplicate configuration options in the configuration? Thanks in advance! EDIT: Clearing the cache / cookies seemed to work. Is this the right way to do http/https redirection? I sort of made it up as I went along.

• OpenSSH (Windows) does not forward X11

  - by Shulhi Sapli

  I'm running Ubuntu 13.04 in VM and I wanted to do X11 forwarding to my host (Win 8), so far it works fine using PuTTY and XMing server for Windows. But I am curious why it doesn't work if I use OpenSSH binaries (it comes together with Git for windows). This is what I've done so far: ssh -X [email protected] (also tried with -Y) then gedit but received error of Cannot open display. echo $DISPLAY came out as empty. So, I try to export DISPLAY=localhost:0.0 but it still won't work. The DISPLAY environment that I set is exactly as when it runs with Putty. I also try changing the DISPLAY to 192.168.2.3:0.0 and other display number as well, but still it won't work. Of course I could just use Putty to make it work, but I was wondering why OpenSSH binaries does not work. I have enabled all settings required in both /etc/ssh/ssh_config and /etc/ssh/sshd_config. If I run with -v option, this is what I get F:\SkyDrive\Projects> ssh -X -v [email protected] OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007 debug1: Connecting to 192.168.2.3 [192.168.2.3] port 22. debug1: Connection established. debug1: identity file /c/Users/Shulhi/.ssh/identity type -1 debug1: identity file /c/Users/Shulhi/.ssh/id_rsa type -1 debug1: identity file /c/Users/Shulhi/.ssh/id_dsa type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_6.1p1 Debian-4 debug1: match: OpenSSH_6.1p1 Debian-4 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_4.6 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-cbc hmac-md5 none debug1: kex: client->server aes128-cbc hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Host '192.168.2.3' is known and matches the RSA host key. debug1: Found key in /c/Users/Shulhi/.ssh/known_hosts:2 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,password debug1: Next authentication method: publickey debug1: Trying private key: /c/Users/Shulhi/.ssh/identity debug1: Trying private key: /c/Users/Shulhi/.ssh/id_rsa debug1: Next authentication method: password [email protected]'s password: It seems that there is no request for X11 (I'm not sure if there is should be one too here).

• Nginx common configuration that I might have missed

  - by ApPeL

  I recently moved from Apache Mod_wsgi to Nginx, and I have seen a major improvement on speed a lowering on memory usage and I am generally very happy with the it. I am not a server expert, so please be gentle. I am wondering if there are any small configuration that I might have missed, that will cause me some issues in the long run...

• XNA Notes 007

  - by George Clingerman

  Every week I keep wondering if there’s going to be enough activity in the community to keep doing these notes on a weekly basis and every week I’m reminded of just how awesome and active the XNA community is. There’s engines being made, tutorials being created, games being crafted. There’s information being shared, questions being answered and then there’s another whole community around the Xbox LIVE Indie Games themselves. It’s really incredibly to just watch all that’s going on and I’m glad I’m playing a small part in all of this. So here’s what I noticed happening in the XNA community last week. If there’s things I’m missing, always feel free to let me know. I love learning about new corners of the XNA community that I wasn’t aware of or just have been missing!

• Help Protect Your Children with the CEOP Enhanced Internet Explorer 8

  - by Asian Angel

  Do you want to make Internet Explorer safer and more helpful for you and family? Then join us as we look at the CEOP (Child Exploitation and Online Protection Centre) enhanced version of Internet Explorer 8. Setting CEOP Up We chose to install the whole CEOP pack in order to have access to complete set of CEOP Tools. The install process will be comprised of two parts…it will begin with CEOP branded windows showing the components being installed… Note: The components can be downloaded separately for those who only want certain CEOP components added to their browser. Then it will move to the traditional Microsoft Internet Explorer 8 install windows. One thing that we did notice is that here you will be told that you will need to restart your computer but in other windows a log off/log on process is mentioned. Just to make certain that everything goes smoothly we recommend restarting your computer when the installation process is complete. In the EULA section you can see the versions of Windows that the CEOP Pack works with. Once you get past the traditional Microsoft install windows you will be dropped back into the CEOP branded windows. CEOP in Action After you have restarted your computer and opened Internet Explorer you will notice that your homepage has been changed. When it comes to your children that is not a bad thing in this instance. It will also give you an opportunity to look through the CEOP online resources. For the moment you may be wondering where everything is but do not worry. First you can find the two new search providers in the drop-down menu for your “Search Bar” and select a new default if desired. The second thing to look for are the new links that have been added to your “Favorites Menu”. These links can definitely be helpful for you and your family. The third part will require your “Favorites Bar” to be visible in order to see the “Click CEOP Button”. If you have not previously done so you will need to turn on subscribing for “Web Slices”. Click on “Yes” to finish the subscription process. Clicking on the “CEOP Button” again will show all kinds of new links to help provide information for you and your children. Notice that the top part is broken down into “topic categories” while the bottom part is set up for “age brackets”…very nice for helping you focus on the information that you want and/or need. Looking for information and help on a particular topic? Clicking on the “Cyberbullying Link” for example will open the following webpage with information about cyberbullying and a link to get help with the problem. Need something that is focused on your child’s age group? Clicking on the “8-10? Link” as an example opened this page. Want information that is focused on you? The “Parent? Link” leads to this page. The “topic categories & age brackets” make the CEOP Button a very helpful and “family friendly” addition to Internet Explorer. Perhaps you (or your child) want to conduct a search for something that is affecting your child. As you type in a “search term” both of the search providers will provide helpful suggestions for dealing with the problem. We felt that these were very nice suggestions in both instances here… Conclusion We have been able to give you a good peek at what the CEOP Tools can do but the best way to see how helpful it can be for you and your family is try it for yourself. Your children’s safety and happiness is worth it.

• XNA Notes 004

  - by George Clingerman

  The XNA community has been crazy busy again. It always make me fee like such a slacker collecting all of these notes as I see the tremendous output from people all over the world and it’s incredible and humbling. There are some amazingly skilled people working with XNA. On another not, I’m going to take a minute to get on my soapbox and say, if you are developing ANYTHING and are not using some sort of source/revision control, START IMMEDIATELY. This applies to teams of one. Projects for fun. And “I back up my hard drive” or “I use dropbox!” does NOT count as using source control. You’ll be doing yourself a HUGE favor if you find one, learn to use it and integrate it into your everyday workflow. I personally use Subversion. It’s hosted offsite at xp.dev.com and I use TortoiseSVN as my front end to interface with the repository. It’s simple and easy to use and has saved me from myself so many time. Honestly, get setup with some type of source control immediately. If you don’t understand how, grab another developer that does and have them walk you through setup and the basics of using it. Ok, I’m done.
