• How to set an executable white list?

  - by izabera

  Under Linux, is it possible to set a white-list of executables for a certain group of users? I need them to be unable to use, for example, make, gcc and executables on removable disks. How can this be done? Edit, let me explain better. I'm dealing with a high school IT system, young geeks that (during the lessons) want to play, surf the net, damage those computer however they can. The major step to achieve this goal was to remove the system they're familiar with and install Ubuntu in all the computers. This actually works quite well, but recent events proved that this is not enough. I want to allow them to execute certain safe programs, like Open Office, and to deny any other program, whether it is preinstalled software, something they carry in usb drives, a downloaded program or a script they program on site. It's possible to remove the 'x' permission on any file on the pc, but of course it would be impractical. Furthermore, they would be able to run anything they download. I thought the best solution would be to make a white-list of safe programs and to deny anything else, but I don't really know how to do it. Any idea is helpful.

• Is there a Mac utility that does low level drive integrity check and repair?

  - by Puzzled Late at Night

  The PGP Whole Disk Encryption for Mac OS X Quick Start User Guide version 10.0 contains the following remarks: PGP Corporation deliberately takes a conservative stance when encrypting drives, to prevent loss of data. It is not uncommon to encounter Cyclic Redundancy Check (CRC) errors while encrypting a hard disk. If PGP WDE encounters a hard drive with bad sectors, PGP WDE will, by default, pause the encryption process. This pause allows you to remedy the problem before continuing with the encryption process, thus avoiding potential disk corruption and lost data. To avoid disruption during encryption, PGP Corporation recommends that you start with a healthy disk by correcting any disk errors prior to encrypting. and As a best practice, before you attempt to use PGP WDE, use a third-party scan disk utility that has the ability to perform a low-level integrity check and repair any inconsistencies with the drive that could lead to CRC errors. These software applications can correct errors that would otherwise disrupt encryption. The PGP WDE Windows user guide suggests SpinRite or Norton Disk Doctor. What recourse do I have on the Mac?

• Recovery disk Windows 8 HP Pavilion g6

  - by fpghost

  I recently purchased a HP Pavilion g6 laptop running Windows 8. I want to either obtain the Windows 8 ISO or make some kind of recovery disk that would allow me to restore the system if things go wrong. The HP Pavilion comes with the 'HP Recovery Manager' which I thought may do the job, but on running it and putting in a DVD-R as requested it seems to just hang for a number of hours without doing a thing (the disk sounds like it's spinning for a few minutes but then goes silent). I then tried 'recdisc.exe' but I get the error System Repair could not be created The device reported unexpected or invalid data for a command. (0xC0AA02FF) Next I obtained my Windows 8 product key using the software ProduKey thinking this would allow me to go to the Microsoft website and download the Windows 8 ISO, but as far as I can tell all that is available is the upgrade which can be used if one is running something like Windows 7. Can anyone advise? EDIT: after a reboot recdisc.exe did work; I think the problem was due to some Windows updates needing a reboot, but never the less I would like a full Windows 8 ISO if possible.

• quad sli with gtx 690 not working

  - by Moaadh

  I have two cards GTX 690 (dual core). I did the Sli successfully. Nvidia control panel acknowledges the two cards as quad Sli. However, the problem is that Windows 7 64-bit Ultimate is showing me the graph memory size as 4 GB while it is supposed to be 8 GB because of the Sli. Also the benchmark from all software is giving me a very low score compared to some other guy's benchmark on YouTube. It gives me a big headache. Does anyone know why this is happening? If so, how can I get Windows 7 to recognize all 8 GB of memory? Thanks for your help in advance. My computer specifications: (Processor: Intel Core i7-3930k @3.2GHz(12CPUs))--- (Memory: 65536 MB Ram 1866 MHz)-- (OS: Windows 7 Ultimate 64-bit)-- (OCZ 240GB as SSD PCIe drive for booting and storage disk)-- (DirextX version: DirectX 11)-- (VGA Card: 2 X EVGA GTX 690 Dual GPU. Each GPU is 2 GB, so total memory should be 8 GB.)-- (MotherBoard: ASUS Rampage IV Extreme)-- Others with lesser specifications get a 2500 score in heaven benchmark while I get 1501 as if it is one card.

• Kindle (client) for Mac--text search or highlighting/notes?

  - by doug

  just so we're clear, i'm talking about the client/software version here--ie, that you install on your Mac or PC--not the device. The Kindle client was recently released for the Mac. I downloaded it and bought a couple of Kindle-edition books to view on this client. Astonishingly, two features i consider to be more or less essential to any ebook reader are missing in the Kindle client, either that, or i can't find them: (i) text searching; and (ii) highlighting text. First, does anyone know how to access the search feature? I'm aware of the "Go To" button at the top middle of the reader window--the options in that menu when you click the button are: "Cover", "Table of Contents", "Beginning" and "Location." "Location" requires that you type in an integer (but it doesn't correspond to page number--e.g., typing "167" brought me to the table of contents), not a search term. Second, there's a button on the upper right-hand corner of the window "Show Notes and Marks" yet i can't find any way to highlight text. The only kind of "note" or "mark" i have been able to record is to "bookmark" a page by clicking the "bookmark" button also at the top of the window.

• Windows 7 automatically logs out when logging in

  - by Luke

  A Windows 7 HP x64 computer is set to automatically log in (no password), but once it starts logging in, it starts to load the desktop after the welcome screen, but before icons or background images are loaded, it goes to the Welcome screen saying 'Logging Off'. I can log in with Safe Mode, and I ran a couple different virus scans, with no detections. I also tried checking the userinit.exe file in System32 (as suggested by MANY users for Windows XP), but it's the same version as a working system. I also checked the registry under HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon for the SHELL and UserInit values, but they look normal. I tried to disable all startup items (through MSCONFIG) to select Diagnostic boot, but then I get a blue screen about the video driver not loading. Any other ideas? EDIT I created a new user, and it could log in no problems. I am thinking it's the NTUSER.DAT file. I just renamed it to NTUSER.DAT.old, then tried logging in as the problem user. I could log in, but as a TEMP profile. His profile folder is now C:\Users\TEMP, and his old folder is still accessible but in the wrong location. EDIT 2 I can't seem to turn off the TEMP profile, so I'm open to other suggestions. Copying the folders (i.e. Documents, Music, etc) does not work, as it creates an additional TEMP.000 then TEMP.001 folder each time the user logs in.

• Is my motherboard failing, or is there some other issue?

  - by ThatGuy

  So, several months ago I put together my own desktop PC. I set up a dual boot to Windows and Ubuntu. Recently, without changing any settings or installing anything new, the wifi stopped working on windows (I use a wifi adapter). It said it was connected, Network settings showed that it was working and running trouble shooting had no results. My internet still works on any other device. I found that removing the adapter from the motherboard and plugging it back in was the only thing that fixed the problem. Reinstalling the wifi drivers did not help. I purchased a new Wifi adapter, but the problem persists. More recently, I had a much more discouraging development. Sometimes, turning on the computer results in a boot loop: BIOS never starts. Instead, the monitor turns on as if it got a signal, then immediately turns off. This loops on it's own indefinitely until I hold down power, hard reset it, and try again. Sometimes it works, sometimes it doesn't. I haven't tested much on the Ubuntu side. It appears that wifi works at least some of the time, but since I've had issues just getting to BIOS I'm not confident the issue is on the software side. I've also noticed issues with some of the USB ports no longer working, but that seems to be off and on. Finally, as of a few minutes ago, I booted to windows to discover that everything was running very slowly. Slow here is a relative word, but I have a Samsung 840 pro SSD and I'm used to applications running nigh instantly, and it was a solid 3 minutes before any of my applications would load. Anyway, my question is this: Is it likely that my motherboard is failing? Either way, what steps can I take to try and pin down the problem and figure out what to do?

• HTTPS Proxy which answers CONNECT with own certificate

  - by user1109542

  I'm configuring a DMZ which has the following Scheme: Internet - Server A - Security Appliance - Server B - Intranet In this DMZ I need a Proxy server for http(s) connections from the Intranet to Internet. The Problem is, that all Traffic should be scanned by the Security Appliance. For this I have to terminate the SSL Connection at Server B, proxy it as plain http to Server A through the Security Appliance and then further as https into the Internet. An encryption is then persistent between the Client and Server B and the Target Server and Server A. The communication between Server A and Server B is unencrypted. I know about the security risks and that the client will see some warning about the unknown CA of Server B's certificate. As Software I want to use Apache Web Servers on Server A and Server B. As first step I tried to configure Server B that it serves as endpoint for the SSL Encryption. So it has to establish the encryption with the client (answering HTTP CONNECT). Listen 8443 <VirtualHost *:8443> ProxyRequests On ProxyPreserveHost On AllowCONNECT 443 # SSL ErrorLog logs/ssl_error_log TransferLog logs/ssl_access_log LogLevel debug SSLProxyEngine on SSLProxyMachineCertificateFile /etc/pki/tls/certs/localhost_private_public.crt <Proxy *> Order deny,allow Deny from all Allow from 192.168.0.0/22 </Proxy> </VirtualHost> With this Proxy only the CONNECT request is passed through and an encrypted Connection between the client and the target is established. Unfortunately there is no possibility to configure mod_proxy_connect to decrypt the SSL connection. Is there any possibility to accomplish that kind of proxying with Apache?

• How to recover Windows Password without reinstalling if you forgot Windows password?

  - by user38908

  Usually, we can recover Windows admin password in two traditional ways. The first is to change Windows password with another admin account; the second is to recover the previous password with the windows password reset disk that had been created before you forgot the password. Take Windows XP for example, 1 At the Windows XP login prompt when the password is entered incorrectly click the reset button in the login failed window. 2 Insert the password reset diskette into the computer and click Next. 3 If the correct diskette Windows XP will open a window prompting for the new password you wish to use. However, we offen ignore the important of security until we have been locked out of computer. Fortunately, there is still the last way that can unlock your computer without reinstalling - erase Windows password with Windows password reset CD, which can recover admin password for Windows 7/XP/Vista/NT/2000/2003.... Take Windows Password unlocker for example, followings are the steps to create the reset CD 1.Download Windows Password Unlocker from Password Unlocker Official site 2.Decompress the Windows password unlocker and note that there is an .ISO image file. Burn the image file onto an blank CD with the burner freely supported by Password Unlocker. 3.Insert the newly created CD into the locked computer and re-boot it from the CD drive. 4.After launched the CD, a window pop up with all your account names(if you have several accounts) select one of the accounts that you have forgotten its password to reset it. Just one press, this software can remove Windows password instantly.

• Help with routing table

  - by user68752

  I have tried to find the answer to my question but not really found a clean and easy solution. I have a box (Ubuntu headless 10.04.1 server, with one Ethernet port) on LAN behind a router (running m0n0wall), that I have successfully installed a PPTP device (ppp0) on, this is working flawlessly (following this link) The thing is I want this box to route all it's internet traffic through the VPN tunnel (ppp0 device) but also being able to access the local LAN on 192.168.1.* subnet. I've succeeded a bit with this, but my problem right now is that I have port forwards (e.g. SSH) done in the m0n0wall pointing to this specific box which forces me to do "add routes" to all boxes that want to access this machine through this specific port. For instance a machine with ip xyz.xyz.xyz.xyz needs to have a static route setup in the routing table on the box to be able to access the box. This is the result of route -n xxx.xxx.137.2 192.168.1.1 255.255.255.255 UGH 0 0 0 eth0 xxx.xxx.137.2 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 yyy.yyy.0.0 192.168.1.1 255.255.0.0 UG 0 0 0 eth0 0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0 Where xxx is the IPs provided from VPN server. yyy.yyy.0.0 is a net that i want to have access to the box, without this I can't access the box from outside the LAN (via port-forwards done in router software, m0n0wall) is there away round this ugly solution?

• How do I setup a secondary incoming mail server?

  - by abrahamvegh

  I currently have a server running Debian 6, with postfix and dovecot handling email. This server hosts email for a number of domains and users, so I use MySQL as my backing store for users and forwardings and everything related. Currently, this server is the only server listed in an MX record for all of the domains it serves. I would like to create a secondary server that would be listed in the DNS with a lower priority (e.g. current primary server is priority 5, secondary would be priority 10), so that in the event that I need to reboot the primary server, or otherwise make it unavailable, the secondary server would receive email, and hold it until the primary server came back up, at which point it would deliver any held email to the primary server. I do not need the secondary server to function as a backup sending server. Users would never need to see the secondary server, they would simply not lose incoming emails if the primary server is down, and they would be unable to send or receive until the primary came back up. How would I go about doing this? I would like to use the same software if they can handle this task, because I’m already familiar with managing them.

• Modifying value of "Rating" column within Explorer for arbitrary file types

  - by Fake Name

  Basically, I have a large body of assorted media (text, images, flash files, archives, folders, etc...) and I'm attempting to organize it. Windows Explorer has a rating column, but there seems to be no way to modify the rating of the files short of opening them in their type-specific software (e.g. Media player, or Photo viewer). However, this does not work when the file is of an unsupported type (.rar, .swf ...), or a directory. I'd be more than willing to consider a file-manager replacement (I've alreadly looked at quite a few, Directory Opus, Total Commander, etc...), or even a solution that stores the rating metadata in a hidden file in each folder, or a separate database. The one real critical requirement is the ability to sort by rating, and being filetype-agnostic. Basically, is there any way to categorize a large collection of assorted files by rating that will work with any file type, including directories? - Ideally, there would be an easy way to add arbitrary columns to windows explorer, and edit them directly. However, there seems to be no way to do this. The rating column is the next best thing.

• What Logs / Process Stats to monitor on a Ubuntu FTP server?

  - by Adam Salkin

  I am administering a server with Ubuntu Server which is running pureFTP. So far all is well, but I would like to know what I should be monitoring so that I can spot any potential stability and security issues. I'm not looking for sophisticated software, more an idea of what logs and process statistics are most useful for checking on the health of the system. I'm thinking that I can look at various parameters output from the "ps" command and compare to see if I have things like memory leaks. But I would like to know what experienced admins do. Also, how do I do a disk check so that when I reboot, I don't get a message saying something like "disk not checked for x days, forcing check" which delays the reboot? I assume there is command that I can run as a cron job late at night. How often should it be run? What things should I be looking at to spot intrusion attempts? The only shell access is SSH on a non-standard port through UFW firewall, and I regularly do a grep on auth.log for "Fail" or "Invalid". Is there anything else I should look at? I was logging the firewall (UFW) but I have very few open ports (FTP and SSH on a non standard port) so looking at lists of IP's that have been blocked did not seem useful. Many thanks

• Are there tools available for trimming PDF margins?

  - by Charles Duffy

  I have an ebook I'm trying to read in PDF format on a Kindle. Unfortunately, the page headers and footers have some content (page number and copyright info, respectively) preventing the device from scaling the actual text to match its usable area viewing area, thus leaving the actual content too small to read. Various tools are available which will trim off whitespace, but the Kindle already does this; my goal, by contrast, is to remove printed matter outside of a defined bounding box, and the only tool I've found for the purpose is moderately expensive commercial software. I could probably generate a mask in Inkscape; split out the individual pages using pdftk, apply the mask to each page individually (outputting to postscript), and recombine the numerous postscript files into a single PDF. However, this decode/reencode steps would be pretty unfortunate in terms of document size; something able to operate with a bit more finesse would be ideal. I have all major operating systems handy (Windows, several modern Linux distros, a Mac, etc) so solutions don't need to be constrained by platform. Suggestions? (I've reported the issue to the author, who mentioned it to his editor, who hasn't done anything about the issue over the course of more than a month, making the zero-work approach evidently nonproductive).

• What needs to be considered when setting up for Linux Development? [closed]

  - by user123586

  I want to set up a box for Linux development. I have a working linux install with the usual toolchain and an IDE. I'm looking for advice on how to approach structuring accounts and folders for development. As the Perl folks say "There's always more than one way to do it." Left to my own devices, I'll come up with several unproductive ways of doing it before figuring out what an experienced Linux programmer would think obvious. I'm not looking for instructions to follow for a specific set of tools or a specific software package. Instead, I'm looking for insight into what decisions need to be made and how to make them, with understanding of the advantages and disadvantages of each individual choice. These are some of the questions that come up: Where to put sources Where to put built object files and libraries where to install what to set in environment variables what compiler flags matter and how do you manage them across several types of builds what configuration entries to make in an IDE how to manage libraries to support multiple environments how to handle different build versions such as debug vs release, or cross platform builds If you are an experienced Linux developer, the answers to these questions may seem trivial and obvious. I'd like to learn to make decisions about these questions that result in as little manual configuration as possible, given some existing sources, a particular IDE, or no IDE at all, a paticular set of development libraries etc. At this point you're probably thinking: Can you be more specific? Sure. But remember that I'm trying to learn how to think about this stuff, not just follow a recipie for a specific set of results. Example: Setup a project that uses CMake for some of its components, autogen.sh followed by configure for others and just configure for a few more: debug builds without an IDE debug builds in NetBeans debug builds in Eclipse debug build in Visual Studio all of the above with release builds for Linux, Mac and Windows. So... **What are your thoughts on an approach that works for all four? Do you have any advice on what to read?**

• Windows 7 not booting after failed SRT (SSD caching) install

  - by david

  This is a fairly new computer, only about a month old. i7 2700k, z68 motherboard, with a 1.5tb WD black HD, and a 128gb crucial M4 ssd. I followed the instructions for setting up ssd caching, the SATA controller was set to RAID, I installed the intel software and enabled acceleration and it said everything went fine. But when I went to reboot, I received the lovely "Reboot and Select proper Boot device" error message. I checked the bios, and it was booting from the correct HD (I tried the only other option anyway just in case, it was the ~50 odd gb of unformatted space left on the SSD) AFter that I entered the raid until (ctrl-i at boot) and removed the acceleration and deleted the raid array (because it was being used as a cache this was non destructive) Still no boot. So I reinstalled win7 directly on the SSD, booted, and checked the HDD to make sure it hadn't been wiped. It hadn't, all the files were still there, including all the windows stuff. I backed up my data to an external drive just in case, but I'd really like to get this install booting again. I trawled the webs a bit, and have tried entering recovery mode and using the bootrec.exe and bootsect.exe to fix it, but to be honest I'm not sure what I'm doing with those. My question is basically: How do I make my harddrive bootable again?

• Fixing Windows install by connecting it's hard drive via USB to a different laptop

  - by Jason

  I tried to upgrade a laptop to SP3, which broke it. I later found out SP3 doesn't work on that 2002 laptop. I can't uninstall SP3, or fix SP2, because the hard drive is now not detected during setup (I've read that's the problem you get). I put the hard drive in a USB drive case and plugged it into my other laptop, and I can read (& write to) the disk okay. (The hard drive won't fit in my other laptop, so I'm using USB.) I need to get that disk back to SP2, or fix whatever files got screwed up causing the disk to not be recognized. I don't want to do a re-install as there are 80GB of files on it I need, and they won't fit on the HD of my other laptop, and also because I no longer have some of the install CDs for software on it. What do I need to do to fix that drive from my other laptop? (I don't want my working laptop (XP SP3) to get screwed with by putting an SP2 disk in the CD drive, or the non-o/s data on the other hard drive screwed with.)

• Ubuntu 10.10 - PC shutdown before boot shortly after BIOS loads

  - by clem

  Hi - Since installing Ubuntu 10.10 from Karmic I've started getting problems with starting up the PC. I've done a complete wipe (Boot and Nuke) of the hard drive and reinstalled Ubuntu 10.10 but the problem still occurs. There is no dual boot on the PC, just Ubuntu. Here is the problem: Each morning, when I turn the PC on from being off overnight, the PC starts up and loads the BIOS. I get the following message : "Verifying DMI Pool Data... K8 NPT Data Change...Update New Data to DMI!....... Then poof the computer shuts off. However, after switching the computer back on around 6 or 7 times after it's turned itself off, it will eventually boot up without any problem. Also, once up and running for a while, I can shutdown and restart the PC first time, without any issues. I have also noticed a problem with the USB mouse being recognised and once I finally get the computer booted up, I need to unplug and then plug the mouse back in to get it working. I've opened the PC up and checked the connections (cables, cards and memory) and it all seems fine. The main issue with troubleshooting this problem is I cannot test any suggestions or fixes until the next morning because once the computer is up and running it will remain so! I do not leave the computer on overnight to save energy. So.. is this a hardware / boot software issue? This is a very odd problem and I have googled to no avail. Any suggestions? Many thanks Clem

• Strange boot problems on 6 month old setup

  - by Balefire

  I've already exhausted my knowledge on this one, so forgive me if this post is a bit long. I built a computer 6 months ago for my wife and it worked fine until last week. Then it randomly shut down and would lock up while trying to boot on the boot screen. I cleared cmos and it allowed me to do startup recovery, but it "failed to fix the issue" so I reinstalled windows on the HD (moving the old install to windows_old). It worked, so I started installing drivers again, but then when I restarted to finalize installations it locked up again. This time, I took the hard drive and hooked it up to my computer, backed up all her files, and then formatted the hard drive before reinstalling it. (again had to clear cmos to let me boot from disk) It installed windows, I installed drivers, and it worked for a few hours but then died during startup again. So, then I got a new HD, cleared cmos, and installed clean again, with the same result as the time before, it worked for a few hours, installed windows updates, then crashed on the 3rd or 4th time turning it on. I decided next to try reinstalling and then going online to see if there were any updates for the BIOS or drivers on the Motherboard, but now I can't get it to even bring up the boot menu, so now I'm just left wondering was it the motherboard, or is it the CPU, or the RAM? The problem was strangely intermittent so I thought it had to be a software issue, since a hardware issue would ALWAYS fail to boot, right? But now it seems to be a hardware issue, because it's not bringing up anything. Any suggestions?

• mail server checklist..

  - by Jeff

  currently we ran into some issues with our mail server setup. im preparing a list of actions that we should enforce and use in order to maintain a proper email solution within our company. we have around 80 exchange users, and send mass emails out almost on a monthly bases to 20,000 + customers each time.. the checklist i currently have: 1) mcafee mxlogic 'cloud' anti-spam functionality for incoming message. 2) antivirus on each computer in company 3) antivirus on exchange and DNS servers 4) setup SPF record 5) setup DKIM 6) setup domainkey 7) setup senderID 8) submit spf to microsoft, yahoo, etc. for 'whitelist' purposes. 9) configure size limits for messages in exchange to safe numbers 10) i have 2 outside IPs for my email server, incase one gets blacklisted, switch to the backup. 11) my internet site rests on a different ip than the mail server 12) all mass emails for company sent through 3rd party company (listtrak.com) 13) setup domain alias, media, enews, and bounce for the 3rd party mass mail software. 14) verify the setup using [email protected] 15) configure group policy and our opendns.org account to prevent unwanted actions and website viewing mass emails: 1) schedule them to send different amounts at different times (1,000 at 10am, 1,000 at 4pm, 1,000 10am next day).. 2) setup user prefences, decide what they want to receive ect. ( there interests) 3) send a more steady flow of email, maybe 100 a week with top new products instead of 20,000k every other month.. if anyone has suggestions or additions/subtractions to this checklist they are greatly appreciated. thank you

• How should I configure backup of my server?

  I have just rented a dedicated server. If it helps this is the config I have: CPU1 Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz (Cores 8) RAM 15975 MB Disk /dev/sda doesn't contain a valid partition table (=> /dev/sda doesn't) Disk /dev/sdc doesn't contain a valid partition table (=> /dev/sdc doesn't) Disk /dev/sdb doesn't contain a valid partition table (=> /dev/sdb doesn't) Disk /dev/sda: 120.0 GB (=> 114 GIB) Disk /dev/sdc: 3000.6 GB (=> 2861 GIB) Disk /dev/sdb: 3000.6 GB (=> 2861 GIB) /dev/sda is a 120GB SSD. This is where I have Ubuntu/lamp installed. It's the drive that will run my site. With the account I got two other drives of 3000GB each which I really don't need but they came with the account. I figured I could use these to back up my main 120gb drive. So a couple of things I wondered were: Should I use these for backups? How should I back up. The data I want to back up is a user uploads directory full of images and the database. Everything else is either in a code repo or backed up some other way. For example, it would be nice to know there is a disk image of the 120gb drive somewhere that I can copy over should there be any problems but equally I don't mind doing a fresh install of all the software and copying over just the images and database dump. Thanks for your advice! (also, happy to not use the two other drives and backup elsewhere if it's more sensible)

• Network card shuts down when stressed

  - by user142485

  I have a network card that functions fine with light use, but quits functioning after heavy use. I replaced it with a brand new one and still have the same issue, also updated drivers. It is a wired D-Link card. The Internet seems fine for a small amount of web browsing but when I run a bandwidth test it starts out fast and slows quickly until the card completely quits; I have a constant ping of the gateway going while I run this and it starts timing out after a couple seconds into the speed test. The card will stay on and the data light on it still flashes some but I cannot ping the gateway or anything else until the computer is rebooted. When I boot into safe mode I can browse and run the speed test fine with no problems. I am guessing that this is probably some program that is loading in regular mode but not safe mode that is causing the issue? I have very limited software (turned off av and firewall) on the computer but I am thinking that I'll just have to start eliminating start-up programs and see if that helps. This is on Windows 7 if that makes any difference. Anyone had a similar issue or have any other suggestions/ideas for narrowing down this problem?

• How to distribute multiple executions of an app across many machines

  - by Salec

  I've got a simulation app (64-bit windows) that runs without any user interaction. This app gathers information and pushes it to a remote MS SQL Server. What I'd like to do is execute this simulation as many times as I can on multiple machines after our nightly build has finished and it has passed the test suite. If possible I'd love to have the ability to configure it to stop after x total runs or if the entire batch has taken over y hours. I've tried using Visual Studio's built in test framework since we already have a test lab set up with multiple agents. I created a single unit test that simply runs the simulation then I created an ordered test and added that single test multiple times (from what I gather, this is the only way to execute the same unit test more than once). I found that ordered tests are only run on a single agent and not distributed which is very limiting. We use TeamCity to perform our nightly builds and I suspect it's possible to implement this on top of that, but I'm fairly new to TeamCity. We also have Jenkins and Bamboo available and I'm open to any other software that would get the job done presuming it runs on a 64-bit Windows OS. Any suggestions?
