• Windows 8 Windows Store (Metro/ModernUI) applications not working (just show 'busy' animation or white screen)

  - by davidm_uk

  I have a Dell XPS 15 which shipped with Windows 7 x64, which I recently upgraded to Windows 8. The process went surprisingly smoothly (given that this was an upgrade, not a complete re-install), and the system generally seems very stable. However, today I noticed that several of the Windows Store apps don't work: they all behave in the same way, launching but then showing a spinning 'wait' animation indefinitely. This is affecting the standard Microsoft Mail, Store, Weather, News, Travel, Finance, Sport, Games and Music apps. The Bing app just shows a Bing logo on a coloured background (but no wait animation). The Calendar, Photos and SkyDrive apps open but then show a white screen. The Maps and Camera apps work without problems. The live tiles on the Start screen are updating correctly, for example the Mail app's tile shows a summary of new mail despite the Mail app's problems. All of these applications were working correctly a few days ago. I'm sure I've used several without problems since the last Windows update occurred on 7th November. Any suggestions on what might have happened and/or how to fix it would be very welcome. I don't need these Windows Store applications, but the fact that they're not working is irritating me.

• Synchronize folder on network, preserving hard links

  - by Waleed Hamra

  I have few computers using Windows XP Pro. I want to synchronize/back a folder from one machine, to another one. This far, It's a simple problem, and I've used FreeFileSync for such operations, with very satisfactory results. But, this all changes when hard links come into play. Today's folder contains lots of hard links, using such backup programs will result in hard links being treated as multiple files, and copied as such, greatly increasing folder size on destination, and defeating the purpose of using all these hard links in the first place. It gets more complicated when we take into consideration the fact that network shares on Windows DON'T expose hard linking facilities, meaning that running a hard-link-aware tool like rsync using --hard-links will be of no use. So my question, how can i backup my folder to the other computer, while preserving hard links? I don't mind installing 3rd party tools to do it, as obviously, the standard windows shares approach won't work... I am guessing there might be some tool that can be installed on both machines and works in a server/client mode? anyone has any idea how to do this?

• Create custom launchers in GNOME 3

  - by hochl

  I'm using Debian testing, and I have been switched to GNOME 3 by the Debian update yesterday. I'm not very comfortable with the UI. I wanted to customize everything like I had it with GNOME 2, but I simply couldn't find any way to change preferences like I'm used to. I've digged some, but all answers I could find did not help me achieve my goals. So please, if anyone knows the solution to this I'd be thankful: 1) I want several launchers that launch terminals, with different arguments and different coloring/title. I have searched everything and there seems to be no menu, no right-click, nothing which is standard in any UI I know. How can I create several launchers in this bar on the left side that launch the same application, just with different parameters? With GNOME 2 this was a piece of cake. 2) I want to switch between different terminals using ALT-TAB. Right now, I'm always just getting to the same, already-opened terminal. When I open two terminals by simply creating the second one by issuing xterm &, I still get one Terminal entry with ALT-TAB, and I have to navigate with cursor keys or mouse wheel to select one of the two xterminals. Instead, I want to open a new terminal when I click the quick launch terminal icon from the bar on the left side of the screen and navigate through them like on KDE/GNOME 2/Windows/any reasonable UI. Can this be done? 3) Is there a trick to make bluetooth devices work like on GNOME 2? Right now, my BT keyboard won't pair anymore, which, as you can imagine, makes me pretty angry. and, if anything fails: 4) How can I switch back to GNOME 2 again? :-) Honestly, who did design this? What were they smoking? I feel like I'm not allowed to do anything except start one of any application that has an icon and just with the default parameters. That can't be true, right? I feel massively restrained by this stuff :(

• Is there any way to synchronize AD users with Office 365 but still be able to edit them online?

  - by Massimo

  I'm performing a migration to Office 365 from a third-party mail server (MDaemon); the local Active Directory doesn't include any Exchange server, and never had any. We will need directory synchronization in order to enable users to log on to Office 365 using their domain credentials; but it seems that as soon as you enable directory synchronization, you can't perform any action anymore on Office 365 users: all changes need to be made on the local Active Directory, and then replicated by the synchronization process. For ordinary users with a single e-mail address and standard features, this is not a big problem; but what about users which need an additional address? What if I need to configure some nonstandard setting, like "hide from address list" or a custom mailbox quota? From what I've gathered, the only supported way to do this, as you can't directly edit Office 365 objects anymore after synchronization is enabled, is to extend the local AD schema with Exchange attributes, and then manually edit them (!). Or, you can install at least one local Exchange server, and then use the Exchange administrative tools to configure the required settings. Is this correct or am I missing something? Is there any way to synchronize user accounts and password, but still be able to edit user settings directly in Office 365? If not (everything really needs to be set locally and then synchronized), is there any simpler way to do this than manually editing LDAP attributes or installing a local Exchange server?

• How do I activate the F_LINE input in a transplanted HP chassis?

  - by admin

  I have an HP Pavilion Media Center PC chassis, vintage 2003 or so and I replaced the motherboard in it with a newer (vintage 2009) HP motherboard, M2N68-LA (Narra 5). I have scoured the internet trying to find pinouts for the motherboard to no avail. My question concerns the front panel audio, specifically Line In. The old chassis was built for AC97 but the new mobo is build for the newer HD audio standard. I figured out by comparison & experimentally how to connect the Mic & Headphone jacks to the HD audio header of the mobo by adding a manual switch to set the SENSE lines. Now all works fine for Mic & headphone. The old chassis also has a front panel Line In jack that the newer HP chassis does not have. However, the new mobo has a 4 pin white connector labeled F_LINE that I believe is a line input. Under Windows 7 I see the two Line Inputs in the mixer but I can't get one of them to become active. The 4 pin F_LINE connector uses the two middle pins for ground, and presumably the other two for left and right audio inputs. There are no pins for sensing on that connector. Can anyone tell me how to use that F_LINE input for the front panel, or how to activate it?

• Windows module installer delaying login, server 2008 R2

  - by Kyle

  We updated our servers this weekend (windows updates), everything went fine except one of our terminal servers now hangs at login with the message, "waiting for windows modules installer." It eventually times out and leaves an event log message that the service has stopped unexpectedly. I have disabled the service and users can now login in a reasonable time frame. However we will need to re-enable the service in order to install further updates. I'm not sure where to start with this one, I'm an entry level admin and my colleagues are on vacation today, thank God this isn't a serious problem. Further details: -It affects all users. -The only third party software on the server is our ERP software and screwdrivers from Tricerat. -The only event log message is that the service has stopped unexpectedly. -The server manager screen does not display any information about roles it just says, "error". -The remote desktop roles all seem to be functioning properly, Remote app works as well as standard RDP. Let me know if there is any further details I can provide, I will be checking this frequently throughout the day.

• Windows 8 install app for multiple user accounts

  - by Robert Graves

  I purchased Adera episode 2 intending to play through it with my son. We each have our own user account on the same PC. When my son logged in, he was prompted to purchase the app which I had already purchased, installed, and played on the same PC. So I checked the Terms of Use. After selecting an app in the store, there is a Terms of Use link on the left side under the Install button. It is almost impossible to identify it as a link unless you put your mouse over it. The Terms of Use are standard across all apps in the store, not specific to particular apps. The terms of use indicates that the app may be installed on up to five devices, but says nothing about multiple user accounts on those devices. However, this Microsoft blog article indicates that it is allowed. Say, for example, that your family has a shared PC. You have previously used your Microsoft account to purchase a game that all your kids like to play. You can install it for each of your kids by having each of them sign in to their Windows accounts on the shared PC, then launch the Store and sign in to the Store using your own Microsoft account. There, you’ll see all your apps and you can re-install the app on your kid’s Windows account. Installing apps on multiple user accounts on a shared PC still only counts as one of the five allowable PCs where you can install apps. So I have two questions: Is it permissible under the Terms of Use to install the app under multiple accounts on the same device? If so, how do I do so given that my son has already signed into the store using his own Microsoft account.

• Suspending/Screen Going Off When Still In Use (Ubuntu & Arch)

  - by luke

  I have a laptop (HP Pavilion G6) that was running Ubuntu and for a while now (at least 6 months) has been having a problems randomly suspending whilst still in use with a full battery and still being charged. Originally the problem was with Ubuntu so I first attempted to disable suspend using every way I could find (gui settings + dconf editor) this didn't work and it still kept suspending so I ended up switching to Arch Linux. Unfortunately not long after switching to Arch Linux I ended up experiencing the same problems. So yet again I modified the settings in /etc/systemd/logind.conf to prevent it from suspending and this time it worked, kind of. Now I am experiencing the screen going off and I have to change to a different tty (by using ctrl-alt-fx, which was something I also found I had to do sometimes when waking up from suspend in Ubuntu) to get the screen to go back on. The strange thing is this only happens when running a Linux distros and only occasionally (e.g. it may happen once/twice a week at most). But when it does happen it can happen multiple times in a row. And it only seems to happen when I am using it. This may just mean that it hasn't happened yet when I am not but generally if I leave it to run something or play a video it hasn't occurred only when I am using it regardless of which program I am using (e.g. it has occurred when using firefox, vim, even when using a virtualbox vm). At first I thought it could be the CPU temperature but after monitoring it I discovered it occurred a lot of the time when my CPU was less than 50 °C. I then checked /var/log/* but could not see anything related to it suspending only a few standard things from when it was woken up. I am really out of ideas and really hoping someone can help. Thanks in advance.

• Looking for easiest, most simple solution to run a customised DNS Server for my local network on Windows 7.

  - by Jamie G

  I need to forward some websites, such as http://testing.server/ to an fixed IP address on my local network. I can do this easily on one computer using the hosts file. However, I need this to work for all machines on my network. I think the best way to do this will be to setup my own DNS Servers and add the custom DNS settings there. However, I'm looking for the simplest way possible to do this - I really don't want to spend hours setting up Unix Servers and running tricky terminal based scripts just to do this! My server is a standard Windows 7 machine. My dream would be a nice simple windows program with a GUI where I could input my ISP's DNS server and it would use those records, unless I had specifically set up my own DNS for a domain to use instead. If it had a web based admin system that was accessible from another computer on the network that would be even better. Does anyone know of anything that can do this? Many thanks indeed.

• rsync per-site configuration file?

  - by Scott

  I know how to configure a per-site entry for ssh, but is there any kind of a client configuration for rsync that allows per-site configuration options and aliases or similar shortcuts like the .ssh/config? I'm curious because I have a minimal ssh server installed on my android phone and I also have a minimal rsync tool on it as well. I'm getting tired of having to root login onto the phone and sym-link both tools to standard places the android OS looks for executables as the ssh server is bare bones and has a typical *bear multi-link binary for the basic unix commands (that does not include rsync) I end up having to include --rsync-path=/path/to/rsync/android/files/rsync every time I want to do any rsyncing of the files on my phone, but this path is always the same. I've gotten around it in the meantime with a glob approach in a shell script wrapper, but this sometimes limits the customization I can do with the rsync call. I'm just wondering if there is anything similar to the .ssh/config file where I can create an alias for my phone (e.g. 'android') where specifying rsync android:/mnt/sdcard will automatically assume --rsync-path=/blah/blah/blah --no-g --no-p --no-t etc. Tre`

• Windows 7 x64 support for Intel GMA 3650 (or GMA 3600)

  - by Loom

  I recently purchased an Intel D2700 MUD motherboard and I cannot find drivers for the Win7 x64 integrated graphics (Intel GMA 3650 aka PowerVR sgs545). The accompanying CD contains Win7 x32 version only. When I run it I got an error: This computer does not meet the minimum requirements for installing the software. I tried to use online utility Intel Driver Update Utility Graphics. I used Chrome, Firefox, Internet Explorer without success. First, UAC prompt appear, and then endlessly spinning progress-bar with text "Analyzing computer...".

• How do I configure IIS to allow access to network resources for PHP scripts?

  - by Dereleased

  I am currently working on a PHP front-end that joins together a series of applications running on separate servers; many of these applications generate files that I need access to, but these files (for various reasons) reside on their parent servers. If I, from the command line, issue a bit of script such as: <?php var_dump(glob("\\\\machine-name\\some\\share\\*")); I will get the full contents of that directory, proving that there's no problem programmatically with PHP reading the contents of a UNC share. However, if I try to execute the same script from the web server, I get an empty array -- more specifically, if I use more explicitly functions designed to "open" a directory like it was a file, I get access errors. I believe this to be a permissions issue, but I am not a server/network administrator type, so I'm not sure what I need to do to correct this and get my script running, and the links I've checked out have not been a terrible amount of help, perhaps due to my background, or lack thereof as far as IIS is concerned, coupled with the fact that we are not actually using .NET for this. Relevant Stats: Windows Server 2008 Standard SP2 IIS 7.0 PHP 5.2.9 I will be connecting to two types of servers: a few other nearly-identical Server 2008 machines, and a machine running embedded XP. Links that have not been particularly helpful but maybe I am just misreading: http://support.microsoft.com/?id=306158 http://support.microsoft.com/kb/207671/EN-US/ http://support.microsoft.com/kb/280383/

• certificate SSH login does not work on 22 but other port

  - by Hugo

  On my Red Hat server, the sshd will not accept my correct certificate login. However, If i start another sshd on another port, it works! (I assume the second sshd loads the same configruation files.) second sshd started with: sudo /usr/sbin/sshd -p 54321 -d #-d is optional and prints debug output ssh strange-host -p 22 -vvv prints: debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,password debug1: Offering public key: /home/me/.ssh/id_dsa debug3: send_pubkey_test debug2: we sent a publickey packet, wait for reply debug3: Wrote 528 bytes for a total of 2389 debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,password debug2: we did not send a packet, disable method debug3: authmethod_lookup password ssh strange-host -p 54321 -vvv prints: debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,password debug1: Offering public key: /home/me/.ssh/id_dsa debug3: send_pubkey_test debug2: we sent a publickey packet, wait for reply debug3: Wrote 528 bytes for a total of 2389 debug1: Server accepts key: pkalg ssh-dss blen 433 debug2: input_userauth_pk_ok: SHA1 fp 0f:1c:df:27:f7:86:49:a8:47:7e:7f:f3:32:1c:7d:04:a3:73:a5:72 So the question is why the difference? I have thought of no way to get any helpful logging from the "standard" sshd to troubleshoot the problem.

• Laptop + External Monitor: Possible to Scale Mouse-crossover Position?

  - by Brian Lacy

  I have a laptop with a 16" screen @ 1366x768 resolution, and a 24" external monitor at 1920x1200 resolution. I'm extending the Windows 7 desktop onto the other screen. The 24" is the secondary monitor, and is positioned so the bottom of that screen lines up with the bottom of the 16" screen. Currently, if I move the mouse to the top portion of the 24" screen, then move left, the mouse will stop at the edge of the 24" screen until I move it down far enough to get into the range of the 16" screen. So that's all pretty standard; but I'm wondering if there's any software out there that will allow me to "scale" the mouse-crossover position, such that if I'm at the TOP of the 24" screen and move left, the mouse will cross to the TOP of the 16" screen, whereas if I'm at the BOTTOM of the 24" screen, crossing over will position the mouse at the BOTTOM of the 16" screen. So then, if the mouse cursor is on the 24" screen at (x,y) position (10,600), and I move 20 pixels left, the mouse is now on the 16" screen at position (1356,384). Anyone know of such a solution?? Note: I also use Ubuntu, so if there's a solution to this for X, but not Windows, I'd be interested in that also.

• How to choose the right PHP Framework for web development?

  - by liliwang

  Hi! I'm a PHP Pro, but haven't use any PHP framework till now, so I have no clue on how to choose a PHP framework. Do you have some tips to help me choose the/a right PHP Framework? I want a stable and secure PHP framework for Projects with about 400 hours development time. It should be possible to use the framework on Shared-Hosting-Webservers. I don't need some AJAX support (I'm using extJS). It would be nice if the framework supports Rapid Application Development and object-relational mapping. Also some of the standard-functions (Authentification, form validation) would be nice. Caching would be a useful, but isn't needed. Needs for a PHP framework: Shared-Hosting-Webserver-Support for Projects between 200 und 400 hours work Developing Modell "Rapid Application Development" supported object-relational mapping supported If possible: Caching Already finished Modules (e.g. Authentification, form validation, ..) Easy to learn Which PHP framework is the right one I am seeking for?

• MySQL Memory Limit Windows Server 2003

  - by Matt

  I am running MySQL 5.0.51a on Windows Server 2003 Standard Edition on an HP DL580 G4 with 3GB installed. One of my database tables has grown to 5.3 GB with an index file of 2.5 GB, which I believe is causing MySQL to be slow due to having to constantly load and unload the index file when updates are made to the table. The server itself seems to be performing OK because MySQL is only using about 500MB of memory (there are other apps running on the system, but MySQL uses the most memory). The table is fairly active with new records getting adding all during day but no deletes, ever. The MySQL server has up to 600 connections allowed, but only small number (10 or 20) would actually be writing to this table. I increased the memory limits in MySQL but since the max connections is so high I don't think I can give each connection 1GB without risking a problem. Is there some tuning that would let just certain connections get a lot of memory? So I have started to look for alternatives to avert the crisis I know is coming soon. Some of the options I have: Upgrade to Server 2003 Enterprise to install 64GB of memory. Question: would 32 bit MySQL be able to access more than 2GB? Would that be 2GB per thread? That would still be smaller than the index table size so it might not solve the problem completely, but it would be better than now. Upgrade to Server 200x 64 bit and MySQL 64 bit. Switch to a *nix 64 bit server. If anybody has suggestions for things to do in the meantime, opinions on which way to go, or other things that I have overlooked I would appreciate the help. Thanks

• Is there a remote desktop or vnc app for the IPad that properly handles Bluetooth keyboard shortcuts?

  - by Steve Bison

  I've tried 4 or 5 remote desktop apps, the most notable being Jump Desktop and Splashtop Streamer. Most of these remote desktop apps have some sort of on-screen keyboard for typing with the IPad, including special keys like shift, control, alt. The special keys act like "sticky keys" meaning they stay depressed until another key is pressed, to make it easier to do key combinations. Even non-standard keyboard combinations like shift+enter work, in this sticky sense. When using a Bluetooth keyboard with the remote desktop apps, both Jump and Splashtop Streamer recognize the shift + letter combination for doing capital letters. However, generically pressing shift, cntrl, or alt does not depress the sticky on screen shift buttons or do anything at all. Only a few combinations are recognized (again like shift+letter, cntrl+C). Most combinations do not work (shift+enter, alt+tab). Even having the keyboard shortcuts work like sticky keys (press shift then enter, not both at once) would be much better than the limited functionality they have now. Is there an app, jailbreak app, or workaround that lets me use bluetooth keyboard properly with remote desktop on the ipad?

• Why is REMOTE_ADDR only sometimes available as an Apache environment variable?

  - by Xiong Chiamiov

  To avoid having to parse X-Forwarded-For in Varnish, I'm trying to just set a header on the SSL terminator (currently Apache) that stores the direct client IP in a header. On our development machine, this works: RequestHeader set X-Foo %{REMOTE_ADDR}e However, in staging it doesn't. Specifically, the header is empty, as illustrated by both varnishlog: 13 TxHeader b X-Foo: (null) (On the development machine, this shows the IP address as expected.) Similarly, logging REMOTE_ADDR shows that it only appears to be populated on the dev machine: # Config LogFormat "%{X-Forwarded-For}i %{REMOTE_ADDR}e" combined CustomLog "/var/log/httpd/access_log" combined # Log file, staging <my ip> - # Log file, development <my ip> <my ip> Since the dev machine is, well, a dev machine, it is different in a number of ways; however, I can't track down which difference is causing this. The versions of Apache are the same (2.2.22), and I don't see anything relevant in any of the standard config files or /etc/sysconfig/httpd. And the rest of the system is reasonably similar, since they're built off the same CentOS 5 base image. I can't even tell from the Apache documentation whether REMOTE_ADDR is expected to exist or not as an environment variable, but it clearly works on one machine, whether by fluke or design, and the inconsistency is driving me mad.

• Take a regular Windows 7 clone with clonezilla (device-to-image)

  - by Mario De Schaepmeester

  I am unexperienced with cloning software and I've decided to use Clonezilla as it seemed best as freeware. I chose device image and left most options standard. I chose expert mode anyway to see what I could configure, and decided to try the lzop algorithm instead of the default one for compression. The rest was left at default. When Clonezilla asked me which partitions to clone (I chose parts to image), I chose the C:\ drive but Windows 7 also creates a 100MB partition on setup for system files (the actual boot partition?). I copied that into the image as well. The reason I didn't choose disk to image is that I also have a data partition that needs to stay intact. Now I'm simply not sure that this is the way to go, should I ever need to restore my disk image. Will Clonezilla know what to do with both partitions and will Windows 7 work perfectly after restoring? Edit: apparantly a similar question has been asked before. The link to the first article in the answer is not relevant to me since it covers a device-to-device clone. It appears the windows installation disk can repair the 100MB partition. As for Clonezilla, it copies "hidden data after the MBR" by default too. I don't know, I feel I'll be allright whether by restoring the partition with Clonezilla or repairing it with the Windows 7 disk.

• How to add a writable folder to the PHP document root on linux

  - by Ron Whites

  We are building an example bash script for our PHP TestCoverage Tool use on Linux. The development environment is Ubuntu 12.04_1 but we intend to have the linux example work across as many linux versions as possible without modification. The example linux script requires a variable be set to the PHP Document Root path and by default uses a small PHP example source to show the user how our GUI and text report shows the covered and uncovered PHP code areas. The linux script is also intended to be easily alterable by the user to automate the TestCoverage display of users PHP code. The problem we are having with Ubuntu 12.04 (any linux?) is that the PHP Apache2 document root is defined in /etc/apache2/sites-available/default as /var/www and /var/www is defaulted with "drwxr-xr-x" read only access. So in order to add our own folder as /var/www/SDTestCoverage we must change /var/www to "drwxrwxrwx" read-write access. So it seems our script (at least on Ubuntu) will need to ... 1. acquire and save the /var/www permissions then do .. 2. sudo chmod 777 /var/www (to make writable) 3. mkdir -p /var/www/SDTestCoverage (create our folder under the document root) 4. sudo chmod 777 /var/www/SDTestCoverage (make our subfolder writable) 5. and finally restore /var/www permissions Thanks and our Questions are .. 1. Is this the standard way (using Ubuntu) one adds a writable folder under the PHP Document Root? 2. Is this the most general purpose way one adds a writable folder under the PHP Document Root on other versions of Linux?

• Setting up logging for a remote backup script

  - by Brian Dainis

  So I wrote up a short script that I am planning to run via a cron job daily to package up my site files and send them to a remote location. I also plan to incorporate DB dumps, but I have not gotten that far yet. My issue today however is that Im am uncertain how to log the output of each command for errors, warnings, or other pertinent information the command may output. I would also like to install sometype of fail safe so if something goes horribly wrong the script will stop dead in its tracks and notify me via email or something. Ok the email thing is not as critical, but would be nice. Does anybody have any ideas for that? Here is what I have so far.

• HSphere - Only sees Apache 2 Test Page after forced shutdown?

  - by Darkwoof

  Hi, I have a dedicated server running on a Dell PowerEdge 850 with CentOS 4.4 and HSphere 3.0 Patch 6 colocated at a datacenter. Last night my hosting company had to schedule a change in the power bar, and I gave the go ahead for them to shut down the server and bring it up when they are done. Since they do not have admin access to the machine, I suppose they did a forced shutdown. When the machine was brought up, I found that all my domains (and sub-domains) are now pointing to an "Apache 2 Test Page" instead of the pre-configured sites that were running prior to the shutdown. This apparently only affects the standard sites running on port 80 - my Webmin instance running at port 1000 is still accessible for example, as well as my HSphere control panel running at port 8080. I've checked the config settings using the HSphere UI for each of the sites, and didn't find anything wrong. I've also tried rebooting the server via SSH, which does not rectify the problem. I've previously done reboots with no issues; the sites would just come right back up when its done, but not this time. I'm guessing some configuration file got corrupted or overwritten this time? Anyone with experience with HSphere and can provide some advice on what's happened and how to solve it? Thanks. (I do not have an active support agreeement for HSphere since Parallels took over and increased the min. license to 200. I only had 25 license for use by family and friends.) Thanks in advance.

• Using Windows as a gateway to the internet

  - by James Wright

  My customer currently blocks outbound RDP and SSH, which means that none of their employees can get access to external Windows and Linux boxes (at the console level). However, a need has recently arisen to give access to an assortment of RDP and SSH endpoints scattered throughout the internet. The endpoint IP addresses are a moving target, and an access list exists to define what those IP addresses are. So now my customer wants to have a single Windows Server that they control as the sole outbound point for RDP/SSH to the internet. Consider it a jump box to the internet. If one of our admins have an access to this Windows box then they can log on, and from there bounce around to RDP/SSH endpoints on the internet. Is a standard Windows 2008 box going to work as a jump box? For example, I seem to recall that Win2k8 limits the number of users that can log on simultaneously, which means that the jump box may not be accessible if lots of users are on it. Advice as to how to make this work..?

• Is it possible to trace someone using Google during an online exam?

  - by George

  I happen to be a professor at a reputed college. I want to design an online exam for over 1000 students via around 50 computers right after the vacation ends. Now the problem is that I have heard that many students use Google on a different tab to find answers when no invigilator is around. I want to know if there is a way to backtrace it after the exams via some kind of history or any other possible way. In our university there is a standard system. I am not good with computers but I will try to explain. Each computer uses mozilla to connect to a server centrally located via an IP. The students open it and enter a unique ID and password to start the exams. Many questions are jumbled and different groups of students give exam in a different time slot. Is there any way to trace it since I want to set an example for students so they won't cheat and give exams in an honest way. Additional details: Since the number of computers are less than the number of students, more than 10 students are going to use a single computer on a single day over a period of 10 hours. After this, if I check the history (and let's say someone even forgot to delete the history and I see it), will I able to figure out who among the 10 has done it? Moreover, is it even practical and feasible?
