• Cross-platform automatic adhoc wifi?

  - by marienbad

  I'm not very knowledgeable about wifi, but I understand the notion of Adhoc networks (Wifi without a router), so... Is there a standard (or widely implemented) way of letting a device "momentarily" negotiate a wifi connection (Adhoc network or otherwise) directly to another device, transfer some data, and then quit, all without any user intervention on either device? For example, let's say I have a PC and an ereader in the same room and there's no nearby wifi router for either of these devices to connect to. I want to send a file from PC to ereader but I don't want to do the work of setting up network, selecting an SSID, or entering passwords. Is that possible?

• word 2010 Macro to name and Save file when opened

  - by Phillip Clark

  I have a word document template and will be using a hyper link in Excel to access the word file. The issue I need to resolve is making sure once it is opened a message field box is "popped" up asking the user to create a new file name ... (in this case the current date) for each time the file is opened. In the message pop when finished entering in file name they click yes and then the save screen comes up with the path/file type (macro enabled document) and the file name they have already entered in the pop up.. All they should have to do from the save screen is click ok and it saves the file to a certain path/folder on the C drive of the computer. Once they finish typing in their notes they click a active x button to save and close and they are finished. If anyone can help with this it would be fantastic.

• log execution of certain commands on linux

  - by jlsksr

  I have to maintain a system (debian) on which several users are allowed to install programs - so I would like to log, for example, if anyone executes "apt-get install" or "apt-get purge", so I can keep track of manually installed packages.. I'm looking for a general way to achieve this; it's not just APT, but several programs/scripts etc. Any ideas? /edit a google-search with few different keywords brought up this: http://serverfault.com/questions/201221/how-to-log-every-linux-command-to-a-logserver http://stackoverflow.com/questions/15698590/how-to-capture-all-the-commands-typed-in-unix-linux-by-any-user http://sourceforge.net/projects/rootsh/

• Selecting a different parent in Family Safety filters for Windows 8?

  - by Zhaph - Ben Duguid

  I've got Family Safety up and running nicely on a Windows 8 Surface, with two parent accounts and two child accounts. When one of the child accounts reaches its time limit, the user can "Ask a parent for more time". However, the next dialog doesn't allow the parents to choose which parent account to use - it always comes up with my account, and my wife can't log in to authorise. How can I allow the her account to allow more time/authorise sites etc? She can use the same Live login on our Windows 7 computers to control these settings, and is listed as a Parent on the Family Safety website.

• FTP Error 550 when trying to access a folder via symbolic link

  - by OrangeTux

  I'm configuring svftp on a linux machine. At the moment local users can login via ftp and they will see listened their home dir. They have write acces to it. No I want the users to write in de /var/www/ dir. Therefore I created an new group apache. Added users to the group and gave the group write access to /var/www. Via the terminal all users can write .var/www/. I created a link in the home directory to /var/www via ln -s /var/www/ /home/user/www ls gives: drwxr-xr-x 2 orangetux orangetux 4096 Jun 23 15:06 ftp lrwxrwxrwx 1 orangetux orangetux 21 Jun 23 15:00 www -> /var/www/ But when I use FTP I see the link but I cannot follow it. Error 550 which means file not found or bad access. How can I solve this, so that the users have access to /var/www via their home dir?

• Remote desktop pressing Windows key randomly

  - by wikiti

  When I'm using remote desktop at work from one specific PC it has a quirk which is really quite irritating. I'll be typing away and suddenly the Windows key will be pressed, things start minimising, explorer launches, workstation gets locked (but it locks the remote workstation, so I have that wallpaper in the background, rather than the wallpaper from the local machine as I would expect). I've swapped keyboards, even though it didn't seem to be related to hardware and it made no difference. Done some internet digging and found someone saying it's related to using windows-l to lock the workstation. I've tried to stop myself using that shortcut to see if it helps and have failed miserably :D It's happening to at least one other user remote desktopping from the same machine to a different PC. Reinstalling isn't really an option (I don't admin the PC or I would have tried it, grr), although I could probably get it done if it would definitely resolve the problem. Any ideas?

• Reset All My Passwords

  - by E-rich

  I know there are some great apps out there for keeping track of passwords (see how-do-you-keep-track-of-all-your-passwords if you aren't familiar). I'm interested in additional features for managing my passwords, particularly to reset all my passwords. I can imagine that this feature would be pretty complicated to implement, considering: websites have different methods for resetting a password client applications most likely don't have a means to change a password except for through a graphical user interface (as opposed to providing a command line command) So, I'm curious if there is a solution out there and I just haven't found it. If not, perhaps I will have to start another side project.

• Java Development in Linux

  - by Zac

  I'm a developer and am brand new to Linux (Ubuntu): I'm wondering what the "best practices dictate" for what FHS directories to install various tools to. Things I'll be installing: Eclipse & plugins GlassFish SVN ...etc. I see that /opt is for holding additional ("optional") software packages, but also see /usr as a place for utils and apps. In another post a user recommended I create an entire partition for /srv alone, and to do my staging there (I assume he meant that /srv is where GlassFish and other servers should go?). So basically: what FHS directories do Linux developers use for which type of tools? Thanks for any input here

• search nfs network volume from mac client

  - by user1440190

  Asked: how does a Mac OSX SL or Lion user search the cluster for a particular file (foo.txt) "From the cluster, you would need to run some form of recursive lookup for the file desired. As an example, using 'find'. RAM-1# find /ifs |grep test.txt /ifs/Elements/avid2test.txt /ifs/Elements/test.txt I would suggest contacting Apple support regarding their recommendation for searching for files on remote file systems from the Mac client itself" OK that's great, but I don't want users using CLI !!! Anyone know a good method (non-CLI)? Spotlight is not an option. BTW cluster is roughly 80TB

• What's normal Taskbar behavior (windows)

  - by Erik

  I'm a fairly new user to windows, and Vista is my first version. I'm a bit confused about the taskbar -- either its behaving oddly or I'm just confused, or I've broken something. When I've got a lot of windows on screen, I thought that clicking on a window's taskbar icon would bring that window to the front. I thought it had been doing that in the past, but I'm not entirely sure. When I click it, it just flashes, a second click minimized, and a third click reopens and brings it to the front. Is this normal?

• What could cause Windows 7 to hang whenever I install something?

  - by Larsenal

  I've had this problem when installing several different programs (iTunes, Adobe Acrobat Reader just to name two). Regardless of what the program is, the install usually gets at least 90% through the process and then just hangs. I don't see anything bad in the event log besides the following (and this didn't occur exactly at the time of install): wuaueng.dll (964) SUS20ClientDataStore: A request to write to the file "C:\Windows\SoftwareDistribution\DataStore\DataStore.edb" at offset 16252928 (0x0000000000f80000) for 32768 (0x00008000) bytes succeeded, but took an abnormally long time (185 seconds) to be serviced by the OS. This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem. I've run check disk and it passed. I've had some problems with BIOS settings in the past with Windows 7, but I'm not sure whether that could be related. Update... I also see this error in the event log: Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. hr = 0x80070005, Access is denied. . This is often caused by incorrect security settings in either the writer or requestor process. Operation: Gathering Writer Data Context: Writer Class Id: {e8132975-6f93-4464-a53e-1050253ae220} Writer Name: System Writer Writer Instance ID: {33493f01-ac1b-4efb-a378-3053ab03100d} One last wrinkle.... I see "Previous versions" of c:\ which look like they correspond to the time of attempted installation.

• Make symlink on Windows of whole tree without modifying the original folder

  - by DarkGhostHunter

  I'm trying to do this: make a symlink of a whole directory "C:/Master", in different folders like "C:\Projects\Alpha\", "C:\Projects\Beta\" an so on. "Master" directory usually changes in files and data. I work on the "Projects/*", where every project folder uses the "Master" files, but every one has new files in them. Let's say, I point to the car engine in every project folder, and inside them I add different kind of wheels. The problem I'm having, as a Windows 8 user, is that symlinks (junction) acts as a window to "Master" - I'm not allowed to add any file inside. I looking a way to reference the entire "Master" directory, and add new files - not edit any of the "Master" ones. It's as described here, but on Windows.

• Linux: Tool to monitor every process, execute-command, shortly, monitor what's happening at the moment

  - by Bevor

  Hello, due to a freeze problem of my Ubuntu 10.10 (it is not isolatable) I though about logging every executable of the kernel somehow in any file to see what happens last when a freeze occures the next time to not lose valuable information. I found acct but this is obviously not what I'm looking for. Actually it logs just user commands and those things. I need something which logs in a much "deeper" level. The best would be some kind of script which records every interrupt. Does anybody know some tool like that?

• Video codec that can be read on clean installs of either Windows, OS X and Ubuntu

  - by fmercille

  I have to make a video that will need to be watched on different operating systems. Is there a "universal" video codec that can be played on Windows, OS X and Linux without requiring additional plugins or player other than those that comes on a default clean install of each of those systems? Compression is not an issue, I'm merely looking for compatibility (e.g. for audio, I would use WAV as a universal codec). Note : I must assume that the video will be distributed in countries where software patents are enforced, and therefore can't rely on the user to install non-free codecs on Linux. Thanks.

• How to print index in a 'for-loop' being executed in remote host through SSH?

  - by YShin

  I want to ssh into a remote host, and then execute a for loop that goes through sequence of numbers to control number of different nodes. ssh user@host /bin/bash << EOF for i in {1..10} do echo $i done EOF If I do this, the output is just 10 blank lines, instead of printing out numbers from 1 through 10. If I execute same code on my local machine, I get the desired output which is ten lines each line printing from 1 through 10. How would one achieve the intended functionality, that is accessing the index in a for loop that is being executed in SSH?

• Notepad++'s pesky EOL Format switching -- how to remove the invisible (default?) keyboard shortcuts Ctrl+M, Ctrl+J

  - by AKE

  Notepad++ lets the user specify whether the end of lines (EOL) format for a file should be entirely in Windows, Unix, or Mac formats. Notepad++ also remember the last one encountered in a file and uses that EOL format when a new file is created. But Notepad++ seems to have some pesky default keyboard shortcuts built-in that can create MIXED format files, creating havoc with this otherwise quite reasonable situation. Specifically: - Ctrl+M puts a Mac style EOL, i.e. (0x0D only), - Ctrl+J puts a UNIX style EOL, i.e. (0x0A only), The hazard is that rapid typing and using the keyboard heavily with other shortcut commands could inadvertantly mean typing oone of these above, each time turning at least one line in the file into another EOL format. So my Question: How can I turn OFF these apparently built-in keyboard shortcuts. Please Note: I've already scanned through Settings > Shortcut Mapper and could not find Ctrl+M or Ctrl+J listed for EOL conversion. Thanks,

(Note: Using Parrallels may save space, but my wife won't go for the user experience)

• How to restrict ssh port forwarding, without denying it?

  - by Kaz

  Suppose I have created an account whose login shell is actually a script which does not permit an interactive login, and only allows a very limited, specific set of commands to be remotely executed. Nevertheless, ssh allows the user of this account to forward ports, which is a hole. Now, the twist is that I actually want that account to set up a specific port forwarding configuration when the ssh session is established. But it must be impossible configure arbitrary port forwarding. (It is an acceptable solution if the permitted port forwarding configuration is unconditionally established as part of the every session.)

• Ubuntu/Linux version recommendation for HP dv6 3122TX?

  - by sanjayav

  I purchased a HP dv6 3122TX recently and after installing Ubuntu 10.10 64 bit I ran into multiple issues like, The wireless driver is not supported by Uubntu. (1) [The driver is RaLink RT3090 ] The ethernet stopped working sometimes for no reason [The driver is Realtek RTL8111/8168B ] "Corrupted low memory at ..." issue which is described as a kernel bug in Ubuntu support forums. (It started to take me to a terminal instead of the GUI and couldn't start x server after that) As I'm not an expert Ubuntu user I got fed up of all these issue and got back to Windows 7. But I need an Ubuntu installation up and running for my development work. What are your suggestions about a reasonable Ubuntu version that I should try? Or a different Linux variation? Should I stick to a 32-bit version? It'd be great anyone can give some advice on this issue.

• which command run in cron returns nothing

  - by Zárate

  Hi there, I've written a little utility in haXe + Neko that needs to execute some GIT commands. To avoid hardcoding the path to the GIT executable I'd like to use the which command to find out where it is. Everything works as expected when running manually from the console, but not when the the app runs on a cron job. I'm aware of the restricted environment (here or here) when you run a script using cron, but still surprised this doesn't work: /usr/bin/which git >> /home/user/git.txt The text file is created but the content is empty. Again, when run from the console it works as expected. Any ideas? I'm running OS X Leopard, if that helps. Thanks : ) Juan

• How small can/should I make my partitions?

  - by Pureferret

  My machine is currently split into 3 user partitions (plus however many Windows and Linux have decided to slyly create) Which are C: Windows 7, D: Data, and E(?): Ubuntu. I'm considering wiping my Windows 7 Install (stupid Skyrim not installing) and restructuring the way my machine operates. I want the partitions for the Windows and Linux install to be as small as possible while still able to function well, and be able to install games on my Windows C: drive. I then want to link from both Win7 and Linux drives to the middle D drive so that the in built My Documents (and etc on windows) folder and my Home folder (linux) share a common location, rather than my current situation which is 3 separate file locations. Something like this: I have 1 TB to play with and I want to know the 'best' sizes to make these partitions when I reinstall Windows (which I need to do anyway) and re-jig everything.

• How to enable the flash player plugin in IE8?

  - by Nik Reiman

  I updated to IE8 the other day on my Vista laptop, mostly because Windows Update kept bugging me about it. As a Chrome user, I don't really care so much about IE8, but I do have to use it occaisionally to test website compatibility. At any rate, flash seems to be completely deactivated, and I don't see a place to re-enable it anywhere in the preferences. I've done a bit of googling on the issue, but only found information about how to disable flash, not how to actually enable it. I have the flash 10 debug player installed, and it works fine with Chrome and Firefox. What could be the matter?
