• Privileged command as part of cronjob

  - by user42756

  Hi, I'm facing a weired problem on a unix-based machine. Here is the story: I have a personal username/password on a unix machine with limited privileges. Whenever I need to execute some commands I have to substitute user using the su command, then I execute it normally. Now, I need to add a cronjob that uses such privileged commands so I added the cronjob on the crontab of the user I substituted to in order to have access to these commands. Strangely, it turned out to me that these commands fail to run for some reason as a cronjob although when I execute them directly from shell (after su) they work seamlessly. Why does this happen? Why do these commands not work as part of cronjobs? Thank you

• Why not commit unresolved changes?

  - by Explosion Pills

  In a traditional VCS, I can understand why you would not commit unresolved files because you could break the build. However, I don't understand why you shouldn't commit unresolved files in a DVCS (some of them will actually prevent you from committing the files). Instead, I think that your repository should be locked from pushing and pulling, but not committing. Being able to commit during the merging process has several advantages (as I see it): The actual merge changes are in history. If the merge was very large, you could make periodic commits. If you made a mistake, it would be much easier to roll back (without having to redo the entire merge). The files could remain flagged as unresolved until they were marked as resolved. This would prevent pushing/pulling. You could also potentially have a set of changesets act as the merge instead of just a single one. This would allow you to still use tools such as git rerere. So why is committing with unresolved files frowned upon/prevented? Is there any reason other than tradition?

• Fastest reliable way to open the terminal?

  - by meder

  I actually had my SUPER_L ( left windows key ) binded to gnome-terminal, but for whatever reason ever since upgrading to 9.04 Ubuntu from 8.10 Intrepid it seemed to break the key binding. It was very handy because I could throw open the terminal with one key ( sorry but alt-f2 and typing gnome-terminal isn't practical for me ). Or perhaps it reset all the keybindings? I remember using xev and some gui type interface that was akin to Win32 registry editor. Anyway, I'm curious as to what you guys use to open the terminal.

• Installing VirtIO drivers in Windows Server 2008

  - by Stefan K.

  We are running a Windows Server 2008 system as a "guest" on a Linux-KVM virtual server (SLES11, with VirtIO support). We have trouble with the system performance and this is possibly due to not using the VirtIO drivers. I don't have much experience with neither KVM not VirtIO. Just heard it this could be the reason for our problem. Questions: The install examples I just found are describing how to install the drivers during Windows setup. Is it possible to install the VirtIO drivers later? We have running software on that system and would like to avoid reinstalling/setup of all these. I already found a page describing how to sign the drivers, which seems to be needed. A good tutorial page (step by step instructions) would be nice. Is there anything like that out there?

• Windows 7: from Geforce 8800 to three monitors?

  - by lance

  I've got a GeForce 8800 that I've quite happy with. It drives my two 23" widescreen displays well. Now I've got a 19" standard display that I want to stick between the two widescreens. My second PCIe 16x slot is unused (as is the PCI slot below that), and I want to add a card to my Win7 x64 system. This 19" display won't be used for gaming, so I don't need anything fancy. Here are two cards I was considering, but I'm wondering if they're bad choices for some reason? If they're both fine choices, which is better and why? Again, I'm needing to power only the 19" standard display with this card, and it won't play games. I just need 1280x1024 in Win7 x64.

• How to tell start-stop-daemon to update $HOME and $USER accordingly to --chuid parameter

  - by iElectric

  I'm trying to run a service that uses $HOME and $USER environment variables. I could set them in service itself, but that would only be a temporary solution. Let's say I have a script test.sh with following content: echo $USER And I run it with start-stop-daemon to see my results: $ start-stop-daemon --start --exec `pwd`/test.sh --user guest --group guest --chuid -guest root Seems like it does not update environment, maybe that should be reported as a bug? I have found a nasty hacky solution, which only works (for unknown reason) on my this simple use case: $ start-stop-daemon --exec /usr/bin/sudo --start -- -u guest -i 'echo $USER' guest I'm sure someone else stumbled upon this, I'm interested in clean solution. $ start-stop-daemon --version start-stop-daemon 1.13.11+gentoo

• Using a random string to authenticate HMAC?

  - by mrwooster

  I am designing a simple webservice and want to use HMAC for authentication to the service. For the purpose of this question we have: a web service at example.com a secret key shared between a user and the server [K] a consumer ID which is known to the user and the server (but is not necessarily secret) [D] a message which we wish to send to the server [M] The standard HMAC implementation would involve using the secret key [K] and the message [M] to create the hash [H], but I am running into issues with this. The message [M] can be quite long and tends to be read from a file. I have found its very difficult to produce a correct hash consistently across multiple operating systems and programming languages because of hidden characters which make it into various file formats. This is of course bad implementation on the client side (100%), but I would like this webservice to be easily accessible and not have trouble with different file formats. I was thinking of an alternative, which would allow the use a short (5-10 char) random string [R] rather than the message for autentication, e.g. H = HMAC(K,R) The user then passes the random string to the server and the server checks the HMAC server side (using random string + shared secret). As far as I can see, this produces the following issues: There is no message integrity - this is ok message integrity is not important for this service A user could re-use the hash with a different message - I can see 2 ways around this Combine the random string with a timestamp so the hash is only valid for a set period of time Only allow each random string to be used once Since the client is in control of the random string, it is easier to look for collisions I should point out that the principle reason for authentication is to implement rate limiting on the API service. There is zero need for message integrity, and its not a big deal if someone can forge a single request (but it is if they can forge a very large number very quickly). I know that the correct answer is to make sure the message [M] is the same on all platforms/languages before hashing it. But, taking that out of the equation, is the above proposal an acceptable 2nd best?

• Matrices: Arrays or separate member variables?

  - by bjz

  I'm teaching myself 3D maths and in the process building my own rudimentary engine (of sorts). I was wondering what would be the best way to structure my matrix class. There are a few options: Separate member variables: struct Mat4 { float m11, m12, m13, m14, m21, m22, m23, m24, m31, m32, m33, m34, m41, m42, m43, m44; // methods } A multi-dimensional array: struct Mat4 { float[4][4] m; // methods } An array of vectors struct Mat4 { Vec4[4] m; // methods } I'm guessing there would be positives and negatives to each. From 3D Math Primer for Graphics and Game Development, 2nd Edition p.155: Matrices use 1-based indices, so the first row and column are numbered 1. For example, a12 (read “a one two,” not “a twelve”) is the element in the first row, second column. Notice that this is different from programming languages such as C++ and Java, which use 0-based array indices. A matrix does not have a column 0 or row 0. This difference in indexing can cause some confusion if matrices are stored using an actual array data type. For this reason, it’s common for classes that store small, fixed size matrices of the type used for geometric purposes to give each element its own named member variable, such as float a11, instead of using the language’s native array support with something like float elem[3][3]. So that's one vote for method one. Is this really the accepted way to do things? It seems rather unwieldy if the only benefit would be sticking with the conventional math notation.

• Applying Service Pack 1 to Team Foundation Server 2010

  - by Enrique Lima

  Disclosure:  I performed the following activities on my Windows 7 SP1 system, Visual Studio 2010 SP1 and a local Basic installation of TFS 2010. As with any deployment of a service pack into a server environment, take your recommended precautions and be aware of the changes you are putting in.  With that said, make sure you backup your databases, and that you have an exit/rollback strategy in the event of an unexpected situation. Team Foundation Server 2010 Service Pack 1 corresponds to KB2182621.  The KB article is http://support.microsoft.com/kb/2182621 The process will be very simple to follow, you will need to execute the mu_team_foundation_server_2010_sp1_x86_x64_651711.exe file.  That will extract files needed and launch the wizard driven Installation. Once this process completes, you need to validate the changes. By looking at Team Foundation Server 2010 Administration Console, you should see the reference to the KB number and SP1. There is also a good reason to validate log locations and records. From the Team Foundation Server 2010 Administration Console. Or from Windows Explorer, go to the C:\ProgramData\Microsoft\Team Foundation\Server Configuration\Logs location and review the logs referenced by the servicing references.

• Drupal 7 on Windows - File Module Problems

  - by TimothyP

  Installed Drupal 7 using the Web Platform installer on Windows 2008 For some reason, the file module, when you upload a file, uses the first few letters of the filename as the unique key to store in the database, which of course causes problems very fast. I'm wondering does anybody have a workaround for this? An AJAX HTTP request terminated abnormally. Debugging information follows.

• How can I make smoother upwards/downwards controls in pygame?

  - by Zolani13

  This is a loop I use to interpret key events in a python game. # Event Loop for event in pygame.event.get(): if event.type == QUIT: pygame.quit() sys.exit() if event.type == pygame.KEYDOWN: if event.key == pygame.K_a: my_speed = -10; if event.key == pygame.K_d: my_speed = 10; if event.type == pygame.KEYUP: if event.key == pygame.K_a: my_speed = 0; if event.key == pygame.K_d: my_speed = 0; The 'A' key represents up, while the 'D' key represents down. I use this loop within a larger drawing loop, that moves the sprite using this: Paddle1.rect.y += my_speed; I'm just making a simple pong game (as my first real code/non-gamemaker game) but there's a problem between moving upwards <= downwards. Essentially, if I hold a button upwards (or downwards), and then press downwards (or upwards), now holding both buttons, the direction will change, which is a good thing. But if I then release the upward button, then the sprite will stop. It won't continue in the direction of my second input. This kind of key pressing is actually common with WASD users, when changing directions quickly. Few people remember to let go of the first button before pressing the second. But my program doesn't accommodate the habit. I think I understand the reason, which is that when I let go of my first key, the KEYUP event still triggers, setting the speed to 0. I need to make sure that if a key is released, it only sets the speed to 0 if another key isn't being pressed. But the interpreter will only go through one event at a time, I think, so I can't check if a key has been pressed if it's only interpreting the commands for a released key. This is my dilemma. I want set the key controls so that a player doesn't have to press one button at a time to move upwards <= downwards, making it smoother. How can I do that?

• Is there a log showing why a Windows server did not restart SQL Server after a reboot?

  - by MerlinMags

  Our server was rebooted after a Windows Update scheduled for 1am, but after the restart SQL Server did not start up, so our websites were unable to display. Usually this process happens with no manual intervention. Is there a log somewhere which might indicate the reason why the Windows startup process did not call SQL Server to get going again? I've looked in the Event Viewer (Application Log) and SQL's own file E:\MSSQL\MSSQL10.MSSQLSERVER\MSSQL\Log\ERRORLOG* but these only contain records of successful startup operations....nothing mentions a failed attempt to start a service or anything like that.

• I installed ubuntu, the installer told me to reboot afterwards. I dd, and now linux wont boot

  - by mandy

  Im trying to dual boot between mac 10.6.8 and ubuntu 11.10. I have a macbook pro 8,1. So i installed from a 10.04 disk because the install window makes more sense to me, and it doesnt give me errors or anything. Also, any versions of ubuntu after that dont boot from disk for whatever reason. (i think its having to do with the efi boot thing. i have to get ubuntu 11.10 to boot from a usb with folders bootefiboot.iso) Then my plan after that was after the ubuntu 10.04 install took care of all the swap and stuff for me without being messy, to upgrade to 11.10. So here i have 10.04 booting successfully back and forth from mac osx no problem. I put in my 11.10 usb and the installer gives me the option to "update 10.04 to 11.10" bingo, jackpot, thats what i want. Everything proceeds as normal, as EVERY OTHER install of ubuntu i have ever done, then the installer finishes and says HEY! im finished! Continue testing or reboot now! So i reboot, and what do i get??? A black screen that says the file system isnt found, to enter a boot disk and press any key. WHAT THE HELL????? so i boot the 11.10 installer again from usb, and select "erase 11.10 and install 11.10", installer proceeds normally, and asks me to reboot. I reboot and get the SAME THING. Please, someone, help me get this right here. This is my first time actually dual booting between mac and linux. Usually i just wipe off osx completely and install ubuntu but i actually need to keep my mac partition this time. I have successfully installed 11.10 on this machine before, but that was when i did a clean install. Help?

• Password not working for sudo ("Authentication failure")

  - by Souta

  Before I mention anything further, DO NOT give me a response saying that terminal won't show password input. I'm AWARE of that. I'm typing my user password in (not a capslock issue), and for some reason it still says 'Authentication Failure'. Is there some other password (one I'm not aware of) I'm supposed to be using other than my user password? I've had this ubuntu before, on another hard drive and I didn't have this problem. (And it was the same ubuntu, ubuntu 12.04 LTS) ai@AiNekoYokai:~$ groups ai adm cdrom sudo dip plugdev lpadmin sambashare ai@AiNekoYokai:~$ lsb_release -rd Description: Ubuntu 12.04 LTS Release: 12.04 ai@AiNekoYokai:~$ pkexec cat /etc/sudoers # # This file MUST be edited with the 'visudo' command as root. # # Please consider adding local content in /etc/sudoers.d/ instead of # directly modifying this file. # # See the man page for details on how to write a sudoers file. # Defaults env_reset Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" # Host alias specification # User alias specification # Cmnd alias specification # User privilege specification root ALL=(ALL:ALL) ALL # Members of the admin group may gain root privileges %admin ALL=(ALL) ALL # Allow members of group sudo to execute any command %sudo ALL=(ALL:ALL) ALL # See sudoers(5) for more information on "#include" directives: #includedir /etc/sudoers.d I can log in with my password, but it's not accepted as valid for authentication <-- That is pretty much my issue.

• Ubuntu server is dropping SSH connections, then not allowing me to log back on

  - by wilhil

  I have an ESX box which I have loaded with two Ubuntu Server machines. During setup, I chose no additional packages to install as I just wanted a lightweight machine for testing. The first thing I did was change the root password via sudo passwd After ESX got on my nerves through lag, I decided to install OpenSSH via apt-get install openssh-server. It did it's business, and I then opened putty and could connect in to both machines fine. The first time it connected, it asked me to add the ssh key as obviously it did not know it. Anyway, the second server is working flawlessly, but, the first seems to be giving me trouble. I was in the middle of typing a sentence when it kicked me off for no reason and when I tried to reconnect, putty gave me a warning that the ssh key had changed and it is potentially dangerous. I attempted to log in anyway and it did not work, just the standard access denied message. Using the second machine, I SSHed in to the first machine and it worked straight away, I then killed the SSH sessions (and possibly SSH server), I then reconnected via putty and I again received the security warning message, but, it allowed me to log on fine. ... I thought "glitch" and nothing more of it, but, it just happened again! I really do not understand this and was hoping someone here can help?

• Hostmonster can't change domains around?

  - by loneboat

  (question imported from http://superuser.com/q/204439/53847 ) Horrible title, but I couldn't think of a succinct way to summarize it to fit. I have HostMonster for my web hosting. I have several domain names under the same account (using the same web space, IP address, etc...). Every HM account has one domain set up as the "main domain", and all other domains are "secondary". The only way I have ever encountered this being an issue is in trying to use HTTPS - since (from my limited understanding) HTTPS encrypts headers, you can't route HTTPS requests to different virtual hosts on a server - only unencrypted requests, since it must look in the request to know where to route it. When I registered for my account, I only had one domain name (A). I have since added domain names (B), (C), (D), etc... At one point I switched domain name (B) to be my "main" domain name - so I could use HTTPS with it. I have since sold domain name (B), and would like to make domain name (A) my "main" one again (as it was before), but HM support says, "no, once a domain name has been a 'main' domain name on an account once, we can't set it up to be a 'main' domain name again. You're welcome to use domains (C), or (D), though.". They tell me the only way to reuse domain (A) as a "main" domain would be to set up a new account and transfer over all my files. I'm confused here. If I have domains (D), (E), and (F), they say I'm welcome to make one of them my new main domain name, just never (A) again, since I've already "used" it once. Calls to support only reveal that they can't let me do it because doing so would somehow "break" my account. Can anyone think of any good reason why this should be so? The only thing I can think is that maybe they're using the domain names as keys in some database or something? But if that's the case, that's ridiculous - they need to reorganize their databases!

• Linux Mint on VirtualBox has no internet connection

  Physical machine: Mac Mini running OSX 10.7.5 Virtual machine: Linux Mint 15 Cinnamon 64-bit Using VirtualBox. I am trying to make the linux connect to the internet. For some reason I can access the host computer with 192.168.2.100. Its set up to show me a web-page that says "It works". This I can see from the linux. But I cannot reach anything on the internet. Either FireFox says "Unable to connect" or when I run nslookup google.com I get connection timed out; no servers could be reached. My setting on VirtualBox under the Network tab are: Bridge Adapter vnic0 promiscouos Mode:Allow All`. If it makes a difference, the host has a WiFi connection to the home router. What have I missed?

• URL is generating a /#!/splash-page

  My site for some reason is generating a shebang - /#!/splash-page on the URL. For example when I type www.modernvintage1005.com, the browser returns www.modernvintage1005.com/#!/splash-page and every subsequent page is /#!/about, /#!/contact, and so forth.

• Storing editable site content?

  - by hmp

  We have a Django-based website for which we wanted to make some of the content (text, and business logic such as pricing plans) easily editable in-house, and so we decided to store it outside the codebase. Usually the reason is one of the following: It's something that non-technical people want to edit. One example is copywriting for a website - the programmers prepare a template with text that defaults to "Lorem ipsum...", and the real content is inserted later to the database. It's something that we want to be able to change quickly, without the need to deploy new code (which we currently do twice a week). An example would be features currently available to the customers at different tiers of pricing. Instead of hardcoding these, we read them from database. The described solution is flexible but there are some reasons why I don't like it. Because the content has to be read from the database, there is a performance overhead. We mitigate that by using a caching scheme, but this also adds some complexity to the system. Developers who run the code locally see the system in a significantly different state compared to how it runs on production. Automated tests also exercise the system in a different state. Situations like testing new features on a staging server also get trickier - if the staging server doesn't have a recent copy of the database, it can be unexpectedly different from production. We could mitigate that by committing the new state to the repository occasionally (e.g. by adding data migrations), but it seems like a wrong approach. Is it? Any ideas how best to solve these problems? Is there a better approach for handling the content that I'm overlooking?

• XNA 4: RenderTarget2D textures getting transparent on fullscreen

  I'm generating a Texture2D object using RenderTarget2D as in the following code public static Texture2D GetTextTexture(string text, Vector2 position, SpriteFont font, Color foreColor, Color backColor, Texture2D background=null) { int width = (int)font.MeasureString(text).X; int height = (int)font.MeasureString(text).Y; GraphicsDevice device = Settings.game.GraphicsDevice; SpriteBatch spriteBatch = Settings.game.spriteBatch; RenderTarget2D renderTarget = new RenderTarget2D(device, width, height, false, SurfaceFormat.Color, DepthFormat.Depth24Stencil8, device.PresentationParameters.MultiSampleCount, RenderTargetUsage.DiscardContents); device.SetRenderTarget(renderTarget); device.Clear(backColor); spriteBatch.Begin(SpriteSortMode.Immediate, BlendState.Opaque); if (background != null) spriteBatch.Draw(background, new Rectangle(0, 0, 70, 70), Color.White); spriteBatch.End(); spriteBatch.Begin(); spriteBatch.DrawString(font, text, position, foreColor, 0, new Vector2(0), 0.8f, SpriteEffects.None, 0); spriteBatch.End(); device.SetRenderTarget(null); ResetGraphicsDeviceSettings(); return (Texture2D)renderTarget; } It's working all fine. But when I ToggleFullScreen() (and vice-versa), the previous textures are getting transparent. However, the new textures after that are being generated correctly. What can be the reason for this?

• Windows 7: Screen will power off, or blank and lock, but not both.

  - by Heptite

  For some reason, my Windows 7 (Ultimate, 64bit) laptop will not power off the display and keep it off if I have the screen saver and/or the timed auto-lock enabled. Either the display blanks (and locks) but never powers off, or it powers off for less then a minute, then the back light visibly powers back on and stays on, even though the screen remains blanked until I touch a key or the trackpad. I've tried varying the screen power down time to greater than, less than, and exactly equal to the blank screen/lock time, with no success. Turning the screen saver and the timed auto-lock off does allow the timed display power down in the power settings to work properly. (Note that I am not talking about system sleep or hibernate. I'm talking about when the machine remains running, but only the display should power down.)

• Powershell Set-Acl fails

  - by Ulrich

  While working on a little backup script I try to change the ACL of a file using Set-Acl in Powershell 1 on Vista and always get the following error message: Set-Acl : The security identifier is not allowed to be the owner of this object. This error persists even if I go a minimal script: $acl = Get-Acl $sourcepath$file $acl |format-list Set-Acl -path $sourcepath$file -AclObject $acl Does anyone know the reason for this error? Obviously I'm not changing the ownership of the file... BTW: What I ultimately want to achieve is to reduce all access rights to ReadAndExecute. Is there maybe an easier way of doing this in Powershell? Thanks for your help! Ulrich

• cdrom drive doesn't work on laptop

  - by bozdoz

  Here's as best as I can describe it: When starting up, the boot order doesn't recognize the cdrom drive, but I can open and close the drive during this time. In Windows 7, I can't open the cdrom drive, and it doesn't recognize it in device manager, disk management, or my computer. In Ubuntu Linux, I can open the cdrom drive, but it still doesn't recognize the cds, and it won't mount. If I reformat everything, would my cdrom drive work again? Can I reinstall Windows without a cdrom drive? I've deleted the upper and lower filters as was suggested in Google searches. Took the disk drive out and checked that it was installed correctly (no reason it shouldn't have been). Still: nothing works.

• Cannot resolve a single A Record from client machine

  - by Alex

  I set up a simple Bind server on my VPS and it is working properly. The problem occurs with my local windows machines, which are connected to internet through the home router. I created an A-record named 'dev' and it is invisible from my local network for some reason, though people from other locations can resolve dev.mydomain.com. Ironically, dev.mydomain.com cannot be resolved for myself only. If I add another A-record, say, 'gamma' then it becomes visible from my local windows machines instantly. So this is just for that particular 'dev' name. The only difference is that I had dev.mydomain.com server on another IP but that was a month ago; all nameservers have been changed since then. I tried to reboot my router and flushed dns cache on windows machines: no result. Thank you in advance.
