  • 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.

  • Every month, scheduled task fails and password must be reset - why?

    - by Ducain
    [NOTE: I posted this originally at StackOverflow but it got no traction there - reposting here.] We have a bit of software installed at a few client locations that runs (via Windows task scheduler) a few times each day. In ONLY ONE of the client locations, we have a unique problem: each month, the task will stop working, after running every day for weeks. Twice now it's failed on the 2nd of the month. When I walk the client through troubleshooting it, we've found that it can't start - access denied. To fix it, we simply re-enter the same exact password, and then off it goes happy as a clam. I've never heard of this issue, and their IT people say they don't have anything running once a month that might cause that. I'm at a complete loss here. Any ideas as to why this might be happening? Further details: Windows XP pro machine. Task is being fired with credentials from a local admin account. Computer is always on, and connected to the net.

  • Uninstalled server 2008 now router won't handle DHCP

    - by john
    My set up is this. server behind router, router has a server and switch connected to it with multiple computers. router used to serve DHCP and DNS, a couple of days ago installed AD, DNS and DHCP on the server, and the server gave out IP's. For various reasons we had to uninstall the domain on our server. I removed AD, DHCP and DNS from the roles and set the router back to serving DHCP and DNS. Now I can't get computers on the network. I reset my router back to factory defaults, and if I plug a computer directly into the router I can get a IP address, but all the computers behind the switch can't get an IP address and can't see the router. All my computers say unidentified network, and if I ping the router it says host is unreachable. On the other hand, my wireless devices are just fine and connect no problem. But for desktops, ipconfig /release doesn't release anything and /renew can't find a server to renew on. My router log shows several FIN scans but they are from innocuous websites (google, netgear) and it shows a couple of smurf attacks but they are all from my external IP. Any ideas? the server isn't even connected to the route right now, and all the computers are set for dynamic IP addresses.. I don't know what else to try? Any help?

  • VMware guest pauses when the host is idle - how do I keep it running?

    - by EMP
    I'm running VMWare Worstation 7 with Windows 7 x64 as guest, Windows XP x64 as host. Inside the guest I run a long-running console application, which prints out progress messages with timestamps on them. Sometimes I leave it running for several hours while I lock the host OS and don't touch the computer at all. When I come back I find that some time after I left it seems to have paused and automatically resumed: the console app hasn't made much progress and there's a large time gap in its progress messages. There's nothing relevant in the host event log, but in the guest Application event log I can see these messages around the time I left: A request to disable the Desktop Window Manager was made by process (VMware Tools Service) The Desktop Window Manager was unable to start because composition was disabled by a running application And later, around the time I returned, this shows up in the System log: The system time has changed to ?2012?-?01?-?12T06:36:46.921000000Z from ?2012?-?01?-?12T03:18:19.953079000Z. That seems to support my theory that it's VMware doing something and not Windows itself. The question is: how do I stop it doing that? I want my application to continue running. By the way, the power options are set to never sleep in both guest and host.

  • Windows 7 - ignore security when reading external drive

    - by w-
    hi, My system hard drive on an XP computer kind of failed (random corrupt sectors). So i got a new harddrive and am trying to recover the files. The filesystem is NTFS. The system i'm trying to use when recovering the files is Windows 7. I'm obviously an admin on this box. The last data i'm trying to recover is stuff in the Documents and Settings folder. I'm using a SATA to a USB cable thingy so that I just plug it in as an External Hard Drive. The problem: In Windows Explorer when i try to copy the data, I keep getting prompted with Security warnings and error messages. It keeps telling me i have to change the owner permissions of the folder and all it's contents. If i tell it to change all the files and folder permissions it takes a really long time because it has to recurse through all the folder contents to change the permissions. Is there a way for me to ignore the file permissions when doing this? thanks

  • Windows won't boot after moving house. How do I solve this?

    - by James
    Ive just moved house and tried to set up my desktop after packing it away and now when I power it on, the BIOS boots up and no errors are found but when my computer tires to boot into Windows 7 a continuous fast beeping sound is made and a black screen is displayed. What I've done so far: Reset to UEFI defauts Played about with RAM, I had 4*4 GB sticks, I took all of them out to test for a mobo error which I have and now im only using 1 stick of 4 GB. Changed my GPU, I tok my gtx580 out and now im using the onboard Intel 3000 graphics driver, the BIOS and uefi are correctly displaying so I no longer think its a GPU based error. Ive check all of the connections and nothing seems to be loose. My HDD setup is: 2 128 GB SSD's in Raid 0 as my main C drive (possibly cause of error?) 1 1 TB Games drive 1 2 TB Data Drive Ive also got a blueray drive connected. After searching the internet im pretty much out of suggestions but im currently downloading a live CD to see if it will boot and if I can access some files on my HDD.

  • How to disable monitor auto detection in Windows 7?

    - by Jay Yother
    I am currently running Windows 7 Ultimate 64-bit with a dual monitor setup with an NVIDIA 7950 GT graphics card. One monitor is dedicated to this machine and the other monitor is connected to a DVI KVM switch. When I switch to my other computer, Windows 7 disables the monitor. However, when I switch back it does not re-enable the monitor. The only circumstance that automatically re-enables the second monitor is when I switch back after Windows has put the monitors into power save mode. I am continually having to bring up the NVIDIA control panel to have it re-enable the monitor. Under Windows XP I would just disable the NVIDIA service to prevent it from auto-detecting the monitor (which doesn't solve the problem under Win7), and in Vista there was a registry hack that would prevent this. It looks as though that has been removed in Windows 7. I have found similar questions posted on this site, but nothing that matches my problem exactly. The following link is the question that comes the closest, but does not provide a solution to the problem. http://superuser.com/questions/96683/how-to-fix-monitor-detection-on-windows-7 Is there a way in Windows 7 to disable monitor auto-detection? Update: I just added a second graphics card to my Windows 7 64-bit machine. I plugged one monitor into each graphics card. Now, when I use the KVM switch to switch back and forth it will re-enable the second monitor like it should. There are however, a few quirks with this. If I have a program maximized on the second monitor and it has focus, when I switch it will move to monitor 1. If I have a program maximized on the second monitor and it does not have focus, when I switch it will behave like it is minimized and when I bring it back up it will show up maximized on monitor 1. Definitely better than it was, but still looking for a way to disable the auto-detection.

  • Does anyone know where I could find a 2 input USB voltage meter?

    - by John O
    What we really need is a tiny UPS, of sorts. We'll be hooking up a solar cell and a battery to a single board computer. Currently, that SBC is a custom Pic32 device, and it does it's own UPS and voltage monitoring duties. I've been tasked with trying to replicate all of its features with off the shelf products... and for the most part I've succeeded. But I don't currently have any way to switch between two sources of juice, or monitor when they're getting low. These guys have something: http://www.mini-box.com/picoUPS-100-12V-DC-micro-UPS-system-battery-backup-system I really like it, the price is well within the budget. We might even work it in though it does 12V and I'll probably be using 5V... there are enough engineers on hand to figure out something. But I'd still have no idea what the voltage was for the PV or battery. I was hoping that there was some simple little USB multimeter thing that I could use to monitor this with, but I can't seem to come up with anything. I've found all sorts of cool hardware, but nothing that will help us. Does anyone know of anything?

  • How to use the outcome of a formula as the value for Vlookup or another IF formula

    - by Steven
    Ok I will try to explain my issue effectively. I am making a GPA sheet in which the value out of 100 is computer in to a GPA value and then in to a letter. In cell N5 i have the value of all their grades (formula: =H3+H4+H5) Now in cell (j6) I have a formula which is giving them a number depending on the value calculated in N5 (Formula: =IF(AND(N5>=60,N5<=63.999),"2.0",IF(AND(N5>=64,N5<=66.999),"2.25",IF(AND(N5>=67,N5<=69.999),"2.4",IF(AND(N5>=70,N5<=73.999),"2.5",IF(AND(N5>=74,N5<=76.999),"2.75",IF(AND(N5>=77,N5<=79.999),"2.9",IF(AND(N5>=80,N5<=83.999),"3.0",IF(AND(N5>=84,N5<=86.999),"3.25",IF(AND(N5>=87,N5<=89.999),"3.4",IF(AND(N5>=90,N5<=93.999),"3.50",IF(AND(N5>=94,N5<=96.999),"3.75",IF(AND(N5>=97,N5<=100),"4",IF(AND(N5<=59.999),"0"))))))))))))) Still no problem... as the values I was looking for comes out (example 84.2 shows up as 3.25 as I wanted). However here comes the problem.... I have tried to use the outcome in J6 to do Vlookup or another if formula, however excel does not seem to recognize the value in J6. For example: =VLOOKUP(j6,B3:C15,2,FALSE)... this returns N/A however if I enter =VLOOKUP(3.25,B3:C15,2,FALSE) it gives me what im looking for. It seems that excel will not register the outcome of my formula as a number. What can I do please?

  • A switch and router between the printer and PC that want to print but cannot

    - by Robert Memo
    IP 192.168.1.5 has a wireless connection to a Linksys router (192.168.1.1) which then is connected to a switch. The switch is connected to a server (192.168.0.2). My printer has IP address of 192.168.0.8. Internet connection is fine on 192.168.1.5. Problem 1: IP 192.168.1.5 can not print using printer 192.168.0.8. Problem 2: IP 192.168.1.2 can not access a shared folder on the the server. The reason for connecting this way is that, the server does not release wireless signal. In order to get wireless signal the Router is connected to the switch. The server is a computer server that only has one outgoing LAN port. Plus, due to inconvinience physical locations, I do not have option to change the physical locations and the way it is connected already. I just want the labtops that only have wireless connection to communicate with the printer and the server. I have tried to change the router IP address to 192.168.0.x like the server and printer. It caused problem for the laptop. The router no longer release internet signals. The router does have IP address from the server 192.168.0.5.

  • what are these weird IP address connections in resource monitor?

    - by bill
    I decided to check out Resource Monitor (on the 'Performance' tab in Task Manager, Windows 7) and I noticed in the "Network" section that the 'System' image name kept making a bunch (~5 at a time) of connections to random IP addresses, it would show anywhere from 1-500 bytes/sec 'sent'. They would stay connected for 1-2 minutes. -All web browsers are closed So, first thing I did was run a trace from network-tools.com on some of these IP addresses. 8/10 were outside of US and did not resolve to any host name. Of the 10 IP addresses I traced, 2 were in US, 4 showed origins in China, and one each to Algeria, Russia, Pakistan, Korea. (!) So, the next thing I did was turn off my wireless card, watch the connections disappear, then turn the card back on, and within 30 seconds more random connections were created by System, with different IP addresses from the first time. The next thing I did was go open Task Manager, Show Processes From All Users, then I killed just about everything that wasn't (what appeared to be) a windows process. Turned on wi-fi, and again within 30 seconds, random IP addresses connect for ~ 1 min at a time, new ones coming and going. I occasionally use bit torrent on this machine, but there was definitely no process that seemed related to bt running after I went through task manager, and bt wasn't open to begin with. So, any ideas on what these connections might be for? I have been using Ad-Aware Free and AVG Free on this computer for a while now, always up to date..

  • Volume is no longer showing in Raid Controller BIOS and in Windows

    - by Gordon
    Hi all, I have installed some critical Windows Updates yesterday and now my external RAID Volume no longer shows in Windows Vista x64. All updates went through successfully. From their description, I cannot see how they should relate to the issue, but this is the only change that happened, so who knows. Anyway, here is the details: I have an external eSata enclosure that is running on a SiI4726 controller. I can connect to the controller with it's management utility from the computer the enclosure is connected to. The three drives in the enclosure show up as JBODs. I had those drives configured to be one logical RAID5 drive. RAID management is done through a SiI3132 SoftRaid controller. The Raid Management Utility just shows empty channels where it usually shows the Raid Group. In the Windows Disk Manager, I can see an unknown unitialized device. This is fine according to the setup manual. What it doesn't show is my Raid drive. It's gone. Also, when booting Windows, the BIOS of the controller used to show the RAID volume before booting the OS. This is not happening anymore. Updating drivers and firmware did not help. I have made sure the drivers and firmware are compatible to each others. And like I said, it used to work before. Any clues?

  • Remote Desktop leaves host unresponsive

    - by Jeff Dalley
    I have my desktop PC at home set up to accept remote connections, and I often connect to it from work on my laptop via mstsc.exe. However, every time I remote to it, I find when I go home that despite the monitor being on - it's not receiving an image and it looks as though the computer is hibernating/asleep. I basically have to restart it whenever I get home and I know there's an answer for why its doing this. More details: When exiting the remote session, I have tried both logging off the account, and closing the RDP window without logging off; both give the same result. When I get home to the desktop I of course try moving the mouse, ctrl+alt+del to see if its responsive to restart, multiple key-press to see if I can get any audio out of it; It seems pretty obvious its sleeping/hibernating in some way: Nothing happens in any of these cases and a physical restart is necessary. Both desktop and laptop are running Windows 7 Ultimate. I'm thinking it really is sleeping/hibernating it, and I'm not sure why because left alone my desktop's power options are set to never turn off the HDD or change its state - I leave it on 24/7. This could be a stupid error on my part but I just can't see it! Thanks.

  • Server Intermittently Inaccessible Externally (but Accessible Internally Continuously)

    - by nicorellius
    I have a CRM on a server on a network. We have a static IP and another server outward facing. We use port-forwarding to map to the CRM, so that when you go to the IP or the FQDN, you get to the CRM: xxx.xxx.xxx.xxx crm.example.com Internally, we can access the CRM by going to crm or crm.example.com Lately, I've been noticing that accessing the server from outside the network times out or gives 503, bad gateway. During that time, I can also SSH (different port, so this works) into the outward facing computer and access the server just fine. I have a robot monitoring the site and indeed via HTTP monitoring the site is going down periodically. I looked through the Apache server access and error logs and nothing stuck out at me so I'm a bit confused as to what could be going on. I also searched the access logs for 503 and found nothing. When I run tracert from outside the network, it appears the packets basically make it through the wider area servers (Comcast city and county servers) and end up dropping at the CRM server's front step. I'm tempted to replace the server because it is older and underpowered but it would be nice to know what is going on. Any ideas what to do next?

  • Stop Windows 7 from accessing or writing to hard drive unless "told" to by me? (More info inside...)

    - by Jeff
    A confusing question, perhaps, but bear with me. I have two internal HDDs set up in a RAID0 array which I use as mass storage. I access the drive very infrequently (once a day at most) and so I have set up Windows 7's power options to turn off idle disks after only 1 minute. This is fine, and the disks are turned off most of the time. However, I notice that Windows sometimes spins up the drives when I really, really don't want or need it to. This causes a 30 second delay as both drives spin up and lock up my system. Some examples of when this happens: 1) When I'm installing something using Windows Installer or Installshield; it seems to me as if they're using the drive with most available free space as the installer cache location... so my big RAID drive has to spin up! Most annoying. 2) Apparently, when I open a Java-based program which resides on my system drive and has nothing to do with my RAID drive! 3) At boot-up and shut-down time. At shutdown the drive spin up only for the computer to immediately shut down! Incredibly frustrating! I've already tried changing the letter of the drive, and at some points have removed the drive letter entirely, which solves the first two issues above. So my question (FINALLY!) is this: is there any way I can mark this drive as being for "storage only", so Windows basically does not see it at all until I actually invoke it somehow? Or is there any way I could set it up so that only specific programs have write access to it? For example, download managers, TeraCopy, etc. etc.? Basically I want it to be a "ghost drive" until I'm ready to use it and to stop Windows from spinning it up all the damn time! Thank you. :)

  • After RAID failure SBS 2008 issues logging in and Exchange store does not mount

    - by Josh R
    today has been one of those days. Yesterday a hard drive in our Dell Poweredge 2900 server failed and the RAID array didn't degrade gracefully, so I called Dell (Server still under warranty) and got an engineer to work though the RAID issues with me. He was a nice guy but didn't do too much. We tried to put the RAID in a state where it was bootable and even though we only lost one disk there are still issues with the server. Once we got the server to boot there was an error message saying that the logonui.exe was corrupted and we needed to run chkdsk. I clicked through the error messages and the login screen never came up. So I power cycled the server and it chkdsk automatically but the login screen didn't appear. I tried safe mode, no difference there either. So the issues I am currently having are: 1) The server boots up, the loading windows screen comes up then it dumps me into a black screen where I can only see my mouse cursor. Ctrl+Esc doesn't work Ctrl+Alt+Del doesn't work 2) Some of the services come up: DHCP, DNS, DFS, and Print come up 3) The exchange information store and transport service don't start - I tried using mmc to connect to services.msc on the computer and start them but they throw an error message of "Can't start because group or dependency failed" Has anyone had a problem like this? Can anyone offer some guidance? Thanks a bunch!

  • Drive security settings in Windows 8 Pro

    - by Donotalo
    My PC OS is Windows 8 Pro x64. Windows 8 seems confusing. D:\ drive is supposed to be used solely by a single user, who is in Users group of the PC. The requirement is... that user will have full control of D drive. Admins will have full control of D drive. All other users can only list drive contents. No file could be opened. My account is admin account. From D drive's property Security tab, I've set the following: Allow "List folder contents" for Authenticated Users group. Allow "Full control" for SYSTEM. Allow "Full control" to specific user, who's supposed to use the drive. Allow "Full control" for Administrators group of the computer. Allow "List folder contents" for Users group. After setting this up, the specific user have full control of D drive. No other user can open any file on D drive. But though my account is an admin account, no file on D drive could be opened from my account! Why is this happening and how files can be opened from my account? Note: All accounts in this PC are local accounts.

  • Made a .dmg for a project; user can't open it - "no mountable file systems"

    - by dragonridingsorceress
    Hello, We don't know a great deal about Macs. We had to make an installer, and were told to try a .dmg So we put together version 1, and it seemed to work. We had one application file, which had our icon, and one folder. The user was instructed to drag these into the Applications folder, of which there was the Mac version of a shortcut in the dmg. Then we were told we needed to update files, and assured that we could do so via drag-and-drop. So we did; we dragged them into the folder in the dmg. We tested it (on the computer we were using to edit the dmg) and it seemed to work. So we burnt it onto a disk (along with a windows installer that actually works!). I've just gotten an email from the recipient. She's got a Mac laptop. She inserted the disk, doubleclicked on it, doubleclicked on the .dmg, and got a Warning: no mountable file systems. Screenshot: http://www.flickr.com/photos/97292258@N00/5101670174/ I have the dmg (not on a disk) and am able to open it with no difficulty. How can we get it to work for our recipient?

  • Graphics artifacts/distortion with Win7 and nVidia

    - by Gepard
    Problem I encounter is rather hard to describe, so I provide a screenshot: http://dl.dropbox.com/u/1732760/video-distortion.png As you can see there are some horizontal stripes in random colors. These stripes appear sometimes in all windowed apps, games and on the desktop too. They tend to stay in place until I refresh window (or force it to to redraw by for example minimizing and maximizing again). They also tend to appear in the same place and shape multiple times, even if they disappear, it's very likely they will be again in the same place after a while. These artifacts do not blink or change if computer is idling. If I don't touch anything, do not use mouse, they will stay in place forever (unless some app redraws its window on its own). I first encountered this problem some weeks ago. Back then I thought it might be cooling problem, so I took out the graphics card, removed dust from the radiator and fan and put it into PC back. I also ran some stress test using Furmark (peak tempearature was ~65C) to see if the problem becomes more intense if the card gets hotter, but suprisingly no artifacts whatsoever appear during the stress test. Graphic card is Galaxy GeForce 7300 GT with DDR3 memory, was never overclocked. Drivers are the latest, from Nvidia site. OS is Windows 7 64-bit, updated. AMD64 3000+, 2GB RAM. I'm running a dual monitor setup with 2 19'' Samsung LCDs and problem is on both, so I assume it's not a monitor or cable issue.

  • 2 routers at home- how to connect with VNC?

    - by Charles Leviton
    I have two routers at home. First router is upstairs and is connected to the cable modem. 2nd router is downstairs and acts as "signal booster" for the 1st router. Devices connected to the upstairs router have IP addresses of the form 192.168.1.n Devices connected to the upstairs router have IP addresses of the form 192.168.2.n. I blindly followed instructions from a website to do this set up, just glad it works! Upstairs I have a PC running Win 7 64 bit. Its assigned IP is 192.168.1.7. I have a VNC viewer running on this. Downstairs I have a 2nd PC running Vista 32 Home edition bit that is connected to the 2nd router and has IP Address 192.168.2.114. VNC server is running on this. It's listening on 5900. There is no firewall. When I try to connect to this downstairs PC from upstairs it fails with message "Failed to connect to server". I cannot ping to this either. If I try to connect to this downstairs PC using VNC Viewer from another computer that's connected to the same downstairs router then it works like a charm. So what's the work around if the viewer is on a different "network"? I don't have any problems doing remote desktop connection from the downstairs PC to the upstairs PC even if they are connected to different routers. Router information- Upstairs- ASUS RTN13U, downstairs- DD-WRT v24 RC-5 Thanks! P.S. I posted this on the Ultra VNC forum as well but that doesn't seem to have a lot of activity, so taking the liberty to multipost.

  • #550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##

    - by gtaylor85
    I've searched serverfault and found this question pop-up quite a bit. Unfortunately others problems aren't exactly like mine, and because I'm a true beginner I wanted some more "specific to me" help. If you don't mind. I just set-up a new computer for a user. Copied over her auto-populate and archive emails. Her email, for the most part, works fine. But when she tries to send anything to [email protected] she gets the #550 5.1.1 error. If she uses the exchange webapp she does not have the issue. I can send email to BSMITH, and so can everyone else. The user, as far as I can tell from the EMC reports, is the only person having emails sent back to them and only from BSMITH. I have googled the crap out of this, and attempted some of the solutions to no avail. I've looked for the bmith account in the disabled accounts and copied and attempted to add "IMCEAEX-_O=CHILD+20STUDY+20CENTER_OU=FIRST+20ADMINISTRATIVE+20GROUP_CN=RECIPIENTS_CN=BSMITH@mydomain.com" as an X500 email. I honestly am just following instructions though and I don't really understand what it is I'm doing. Diagnostic information for administrators: Generating server: FS2.FS1D.local IMCEAEX-_O=CHILD+20STUDY+20CENTER_OU=FIRST+20ADMINISTRATIVE+20GROUP_CN=RECIPIENTS_CN=BSMITH@mydomain.com #550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ## BTW I love this site and only found out about it a few weeks ago. My girlfriend now loves the photo.stackexchange. So thanks for such a helpful community.

  • is there a man in the middle attacking to my server machine?

    - by GongT
    My server works well about half a year. But a strange thing happened (several hours before). This server has two IP-address 58.17.85.19 & 117.21.178.19 When I navigate to http://58.17.85.19, nothing different as before. But http://117.21.178.19 will return a "302 Object moved" and become a "redirect loop" I do some test: ($cmd = "wget http://117.21.178.19/?xx=$RANDOM --max-redirect 0 -S --no-cache -O -") Step by step: run $cmd on my PC and my firend's one (we live in two side of China, far away). - got 302 run $cmd on this server - got 200 OK (content is correct result of index.php) run $cmd on another server in same computer room - got 200 OK telnet from my PC and build an HTTP request (type by hand) - got 200 OK shutdown php-fpm, run $cmd on my PC - got 302 run $cmd on server - 502 Bad Gateway shutdown nginx, run $cmd on both the server and my PC - Connection refused. create iptables rule, refuse any connection to 58.17.85.19:80. run nc -l 80 -k -vvv on server and run $cmd on my PC NC show me that.... Server accept connection (Connection from [my ip]) My connection closed ! (Remove fd xx from list) wget dump out response - got 302 I know that, normaly, NC will accept connection, then dump HTTP request from client, and client will wait for response. this connection will open forever(infact client will close connection becouse timeout), becouse NC can't give any response. So... where my request gone? who send an response to the client? some virus on my server system? If so, why 58.17.85.19 didn't has this error? or... I was attacked by a middleman?

  • Recovering data from an external hard drive

    - by CCallaghan
    I have a WD Elements 2GB hard drive (formatted NTFS). I accidentally kicked out the USB cable while writing data to the disk, and now I can't access most of the data. Although this was ostensibly my backup drive, there is a great deal of important material on there which was only on there. I realise how idiotic this makes me. (So, formatting is not an option.) Things I've tried/information I've gathered: Windows Explorer will recognise the drive itself. However, it will not access most directories therein (and will sometimes crash when exploring). I can access all of the directories through the command line, but the dir command will often report that it can't read any files in most of the directories. The situation was similar when I hooked it up to an Ubuntu machine: the file explorer crashed, but I could access directories - but not files in those directories - via terminal commands. Several files I tried to copy out either resulted in an I/O error being reported or resulted in the command line crashing. The Disk Management utility on Windows reports a healthy disk formatted as NTFS and not RAW. It also indicates the correct amount of space used up and its capacity (so it seems that the files are not deleted). I've tried to run chkdsk, but that hangs on Step 2 (checking indexes) at 74%. Step 1 reported no bad sectors. I tried Recuva, but that didn't seem to work (stalled at 0% for half an hour). I should also note that the disk doesn't seem to be spinning smoothly; it seems to be chopping back, like it's reading the same sector over and over again. I noticed this after I kicked out the cable. Any help would be greatly appreciated. Update: It would seem the problem has taken a turn for the worse. The external hard drive now shows up on my computer as a local disk and is not mountable by Linux.

  • Reset sound volume in Windows 8

    - by Svish
    There seems to be a bug in Windows 8 causing the maximum volume to become lower than it really should be. I'm now at a stage where I put the volume up to max and the sound is still very low. I have a couple of Logitech Z-10 speakers with a display on them and when I touch the increase volume button on that it shows me the volume (but not able to increase it) is actually below middle even though Windows claims it to be maxed out. Is there any way I can reset the volume in Windows 8 so that I can get it up fully max again? A registry setting or something? Really don't want to have to reinstall windows or drivers or anything like that cause if it is a bug it'll probably happen again and I really don't want to have to do that every time this happens :p Any ideas? Manged to fix it by unplugging the usb connection to my speakers, turning the volume down on my computer and up on the speakers, and finally reconnecting the usb connection. Seems to have been an issue with the speakers and not Windows this time. BUT, I'm still curious how you can adjust/reset the Windows 8 sound volume without using the volume controls. Like, where is the value of the current volume setting(s) really stored? And can you manually adjust them?

  • VirtualName-based local development host behind corporate proxy (MAMP)

    - by geerlingguy
    I am behind a corporate proxy server/firewall, and this firewall seems to not be too happy with my idea of local development. On my home computer (Mac/Leopard), I have MAMP running, with a rule in /etc/hosts that directs dev.example.com to 127.0.0.1, and I have a virtualhost set up in the httpd.conf file which works great for me. However, at work, I set up the exact same configuration, but am not able to access dev.example.com, likely due to some address/DNS translation going on via the proxy server. Here are the relevant details from Terminal: $ ping dev.example.com PING dev.example.com (127.0.0.1): 56 data bytes 64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.025 ms $ host dev.example.com Host dev.example.com not found: 3(NXDOMAIN) I've tried adding dev.example.com to the list of bypass addresses in System Preferences (the 'Bypass proxy settings for these Hosts & Domains' list), but that had no effect. Is there any way I can develop locally using name-based hosts at work? I can access localhost, but can't get to the dev.example.com (or any other custom virtualhosts) here at work, which complicates other matters related to the sites on which I'm working...
