• Intermittent CNAME forwarding

  - by Godric Seer

  I host a personal website on an old desktop that is LAMP based. Since I have a dynamic IP, I use no-ip to make sure I have a working domain name at all times. I also have a domain I have bought on GoDaddy where I have a CNAME record forwarding the www subdomain to my no-ip domain. At all times, I can connect to my website through the no-ip domain without issue. For the past several weeks, I never had an issue using the GoDaddy domain to connect (ssh or https). As of today, however, the GoDaddy domain only works for about 10 minutes at a time. I get server not found errors most of the time. Also, if I happen to be using the GoDaddy domain for an ssh connection, the connection will freeze. I have attempted to run tests using a couple of online DNS check websites, but have not gotten any errors at any time. I also contacted GoDaddy support but they had no issues connecting to the website, and therefore did not see any issues. I would like advice on how I could debug/resolve this issue. Since the problem appeared without me changing anything on my end, I hope it will resolve itself, but knowing the cause in case it happens again would be preferable. EDIT: I changed the configuration in GoDaddy to create an A (Host) that points at my current IP. This works fine, so I can access the site through the GoDaddy domain without the preceding www. I am currently waiting for a new CNAME record to propagate that points the www subdomain at the main host, rather than my no-ip domain.

• QNAP NAS 509 (LINUX) - how to unmout busy volume and find physical disk?

  - by Horst Walter

  On my NAS QNAP TS 509 I do have a technical issue. I need to run e2fsck. This works fine for me on md0 (see below), but how can I unmount the busy devices md9 and sda4 in order to do the same. Whenever I try, I fail because the device is busy. [This part is solved, see below] In order to further track down the issue, I'd need to sort out the physical disk to device relationship. How can I find out this, e.g. md0 is a stripped volume on 2 disk (but I need to find out on what physical disk). Remark: As you can easily derive from my questions, I am not a Linux expert, but manage to get along. /dev/ram0 124.0M 94.1M 29.8M 76% / tmpfs 32.0M 80.0k 31.9M 0% /tmp /dev/sda4 310.0M 103.9M 206.1M 34% /mnt/ext /dev/md9 509.5M 39.2M 470.2M 8% /mnt/HDA_ROOT /dev/md0 1.8T 1.4T 444.7G 76% /share/MD0_DATA tmpfs 32.0M 0 32.0M 0% /.eaccelerator.tmp -- Added -- QNAP seems to be based on Busybox. I do not find something like init / telinit / runlevel. At busybox docs it says that I need to run the below. But in /var/service sv is not available. I want to go to single user mode to unmount the devices. # cd /var/service # sv d * # sv u getty* -- Added, thanks A4L -- This QNAP Box runs a special flavor of Linux, so not all SOPs do apply. In my particular case I found a services.sh script, stopping all services. After that the drive could be unmounted. The information passed by A4L is valid and worth reading it, maybe I'll profit from it next time. Links: http://unix.stackexchange.com/questions/19918/umount-device-is-busy and http://unix.stackexchange.com/questions/15024/umount-device-is-busy-why So the unmount issue is solved, still looking for the best option to find the physical to volume mapping.

• Mac OS X: remove write-protect flag from file in Terminal

  - by Albert

  Hi, I have a file on a FAT32 volume which is shown as write-protected in Finder (so I cannot move it). Removing that write-protected flag in the information dialog works just fine. However, I have many more such files and I thus want to do it via Terminal. I already tried via 'chmod +w' but that didn't worked. 'ls -la' showed me that they are already just fine ("-rwxrwxrwx 1 az az " where az is my user account). Then I thought this might be stored in some xattr properties but 'xattr -l' didn't gave me any entry. Then I thought this might be some ACL setting (whereby I thought they would be stored as xattr but let's try it anyway) - and some Google search returned me something with 'chmod -a' or 'chmod -i' or so. All these tries only give me chmod: No ACL currently associated with file" or chmod: Failed to set ACL on file...: Operation not permitted". But I definitly have no write access to the file because I cannot move it or do any other change to it (in Terminal). Removing the write-access flag in Finder solves that.

• Mac Security - Which one?

  - by Bob Rivers

  Hi, Recently I had my credit card cloned. A few hours after shopping at an online store (in which I trust and buy since 2006) I received a call from my bank asking if I recognize a $5,000 debt to a store(?!) called Church of Christ... I'm a Mac user (OS X 10.6.3). I always kept my system updated and I have firewall enabled (in my Mac and in my broadband router), but I decided to adopt some kind of protection. I don't want to rise passionate discussions. Real or not, snake oil or not, I need to have back my peace of mind... I read this and this posts. I selected two software that I think that could help me (both have more features other than just an antivirus). Does someone have feedback about Intego's VirusBarrier X6 or Trendmicro's Smart Surfing? Intego solutions seems to be better, but TrendMicro brand/name is stronger in corporate environment, so their solution should be good. Both solutions have 30 day free trial, but I would like to hear something from you. Any other solution that I should look? TIA, Bob

• Thunderbird alerts when expected email does not arrive

  - by user871199

  I am on Ubuntu 12.04 using Thunderbird as email client. Both are up to date in terms of updates. I have bunch of nightly jobs that do the work and send a status mail. It gets tedious if you keep getting same/similar mails every day so I ended up writing a mail filter rule which causes emails to end up in their respective folders automatically. If things are going ok, I really don't need to read emails. Failure emails are sent to different alias - if the job runs. We recently discovered that one of the job had not run for few days as someone accidentally disabled it. In order to avoid such problems in future, I would like to setup thunderbird in such a way that if I don't get email from given address within given duration, it should alert me. My dream solution is to set up frequency - some jobs do run every 4 hours. Is this possible? Can I setup Thunderbird (preferred) or other email client for reminding me when expected email does not show up. Based on comments and answer I received, here are the reasons why I would like to use Thunderbird. We are already using Thunderbird. It has calender support via plugin, so I suppose someone is already watching time to remind us about the event. May be this another type of event. Additional job is one more failure point, may complicate life if it has to monitor multiple hosts. Additional tools - same thing, one more failure point. Thunderbird can be run across all the platforms we are using - Windows and Ubuntu. It sort of becomes platform independent solution.

• Improving abysmal 802.11n wireless network

  - by concept

  I am in desperate need of help to improve the abysmal performance of my 802.11n wireless network. At best I get 30Mbs (this is an internet download) from a technology that boasts 300Mbs, even worse is the LAN where to date best i have ever gotten is 1Mbs.

• Does any economically-feasible publicly available software compare audio files to determine if they are dupes?

  - by drachenstern

  In the vein of this question http://unix.stackexchange.com/questions/3037/is-there-an-easy-way-to-replace-duplicate-files-with-hardlinks is there any software that will automatically parse a library of my songs and find the ones that really are duplicates that one can be eliminated? Here's an example: My brother used to be a huge fan of remixing CDs. He would take all of his favorite tracks and put them on one. Then he would use my computer to read them in. So now I have like 6 copies of Californication on my HDD, and they're all a few bytes difference overall. I have hundreds of songs in my library like this. I want to trim them down to having uniques. They don't all have correct ID3 tags, so figuring out that Untitled(74).mp3 is the same as californication.mp3 is the same as whowrotethis.mp3 is tricky. I do NOT want to consider a concert album and a studio album rip to be the same (if I just did artist/title matching I would end up with this scenario, which doesn't work for me). I use Windows (pick your platform) and will be getting an OSX box later in the year. I'll run Linux if that's what it takes to get it organized. I have unprotected AAC and mp3 files. Bonus points for messing with WAV or MIDI and bonus points for converting from those into MP3 (I can always use Audacity and LAME to convert later if I know they match or to convert ahead of time if that will make things easier). Are there any suggestions, or do I need to goto Programmers or SO and build a list of requirements for comparing these things and write the software myself?

• Why Is Web Sharing Broken on My Mac?

  - by Sam Murray-Sutton

  Background: I use my Mac for web development, running copies of web sites locally. I recently installed the Snow Leopard update, which to all intents and purposes seems to have gone fine, except... What's not working? Web-sharing; more specifically I can't turn it on via preferences. The preference pane just hangs when I try to. So Apache doesn't start on reboot. I can start Apache by hand, but I don't know enough to either setup apache to start with the computer, or to properly fix web sharing. Further details My Apache error log shows nothing on when the system boots up (as I would expect). This is the error message when I try to start web sharing from the sharing preference pane. 28/09/2009 10:58:05 System Preferences[834] setInetDServiceEnabled failed with 1 for org.apache.httpd Here's the messages given when I start apache from the command line.

Any help would be greatly appreciated. UPDATE I have added an answer of my own below - I was able to solve it thanks to being pointed in the right direction by the comments below, so thanks very much. But I'm still not totally clear as to what caused the problem or how my solution addressed it, so I'm leaving the question open for now.

• Browser history, by window

  - by Alex

  I use Chrome --but can switch to another browser if the feature I am about to describe is available. Browsing history, AFAIK in Chrome is sorted exclusively chronologically. Very often however, I will be working on a particular task on my laptop and have multiple (read: a lot) of tabs open in a single Chrome window for that task. Before finishing that task, I may need to work on something else --so I will open another window and minimize the other one, and start researching an entirely different issue. Over the course of a day, I may end up with 10-15 windows with many tabs each. This raises two issues: (a) memory usage and (b) quickly switching between the most relevant two or three windows. I solve these two problems like any regular guy probably would --closing windows. I want to be able to reopen specific windows that I have closed, such that the tabs that were open in that window at the time the window was closed will reopen. Ideally, closed windows will be sorted by the time they were closed and identified by the tabs that were open (even more ideally, I would be able to name these windows (contemporaneously or in the history menu)). Now that I describe this, what I am asking is: does any browser offer the ability to "save and close" windows? (This is distinct from an option to auto-restore tabs upon reopening the browser) Thank you.

• Setup for a live (low-latency) audio video broadcast over Wi-Fi?

  - by Majal Mirasol

  The Upgrade We are capturing audio (from mixer) and video (from a camera) from a main auditorium and passing it to separate rooms within the building. We used to have done this via manual audio/video cables and wires. We wanted to "upgrade" the system and wirelessly broadcast the stream via Wi-Fi. The Problem In our current setup (Wirecast running on A10 on a Wireless-N network), we have the problem of delay. Our streams are delayed from a minute up to five minutes on the clients (laptop/iPad/Android). This had not been a problem from the previous wired connections. Since the wireless network is local, we thought that a delay of less than a second should be achievable. Our Question And so it goes. Anybody there who has any experience for a setup that has both low latency and at the same time user-friendly to clients streaming in the program? Any recommendations would be highly appreciated. (Our current setup in on Windows 7, but setup on a dedicated Linux box is preferred, if achievable.)

• Cleaning a proxy/phishing trojan from Windows XP computer

  - by i-g

  I am trying to remove an interesting trojan from a Windows XP computer. It manifests itself as a phishing page (screenshot linked) that appears after the user tries to log on to eBay. So far, I haven't found any other web sites that are affected. As you can see, the trojan intercepts browser connections (all installed browsers are affected) and injects this phishing page. The address looks like it's ebay.com, but HTTPS verification doesn't work (no lock icon or green bar in Firefox.) At some point, Trojan.Dropper appeared on the computer. I removed it with Malwarebytes Anti-Malware. Although it reappeared several times, it seemed to be gone after I booted into Safe Mode and did a full system scan with MBAM. Now, however, a different trojan has appeared on the machine; I suspect it was installed by Trojan.Dropper. So far, MBAM, Ad-Aware, and Spybot S&D have been unable to remove it. I've looked for it in the HijackThis log but haven't found anything conclusive. Has anyone run across a trojan like this before? Where would I start looking for it to remove it manually? Thank you for reading.

• DNS lookup of GTLD servers using dig

  - by iamrohitbanga

  I ran the following command on linux >> dig . I got the following response ;; AUTHORITY SECTION: . 281 IN SOA A.ROOT-SERVERS.NET. NSTLD.VERISIGN-GRS.COM. 2010032400 1800 900 604800 86400 why does the response not contain the IP address of the root server? what do the numbers at the end of the reply mean. one of them is probably (definitely) the date. why does it report 2 root servers a.root and nstld.verisign? when i send the following queries dig com. ;; AUTHORITY SECTION:com. 51 IN SOA a.gtld-servers.net. nstld.verisign-grs.com. 1269425283 1800 900 604800 86400 again i do not get the ip addresses. when i query for the gtld server specified i can get the ip address. why is the response of dig net. same as that of dig com. except that instead of 51 we have 19 in the response.

• How to prevent getting infected by rogue security applications

  - by Ieyasu Sawada

  My computer never got infected with a virus before, because I'm using Web of Trust browser plugin, sandboxie and Avast Free antivirus. But today, it got infected with a rogue security application called antivirus.net. I have already removed it using MBAM, SAS, and Kaspersky Virus Removal Tool. And by the way, I was using MSE when my laptop got infected. Seems like the rogue application just killed off the MSE process. And I never even got a warning. I was using the wi-fi from our school, which I think is the cause since most of the computers in our laboratory has rogue applications on it. My question is, how do I prevent this from happening again? It took me about 6 hours to disinfect my computer and I don't want it to happen again. Please enlighten me if these rogue applications really just pop out of nowhere. Note I'm not dumb enough to agree with installing rogue security applications. It just came out of nowhere. I'm happy with MSE, well not after it let antivirus.net penetrate my computer. I've done a little bit of research and it says that it needs the permission of the user to actually install it in the computer: http://www.net-security.org/malware_news.php?id=1245 http://en.wikipedia.org/wiki/Rogue_security_software Is it possible that other computers in our school network have agreed to install those? Or maybe the network admin?

• Accidentally mounted a ReiserFS drive as MBR on my windows box - how do I recover?

  - by Ryan

  I had a WD Netcenter with a 160GB drive that kept dropping off the network. I opened up the enclosure and removed the hard drive, connected to a Windows box without knowing the drive used ReiserFS.... When mounting on the Windows box, I chose "MBR" as filesystem. 70GB of data corrupted: 90% of data is word documents, excel spreadsheets, and jpg's - all mission critical. Attempted recovery on Linux box (ubuntu) using TestDisk: I could see the container, but couldn't get anything out – according to TestDisk this was because I chose "none" as filesystem. Attempted recovery using Nucleus Kernel Recovery for windows: 98% of what was recovered is incomplete and/or unusable. I need to know if a way exists to recover or rebuild original ReiserFS MBR, or what tools/techniques might give me the best results in recovering the data. Found a Windows version of TestDisk and I ran it yesterday - here are the results: TestDisk 6.14-WIP, Data Recovery Utility, May 2012 Christophe GRENIER <[email protected]> http://www.cgsecurity.org Disk /dev/sda - 160 GB / 149 GiB - CHS 19457 255 63 The harddisk (160 GB / 149 GiB) seems too small!

• Chipset fan on the frtiz - compressed air hasn't fixed anything - is there anything I can do?

  - by Anthony

  Yesterday, my computer started to make an annoying whining noise. Knowing that this is likely a fan issue, I opened the case and proceeded to determine which fan was causing the issue. I got some compressed air and tried cleaning out the dust around it (and the rest of the computer while I was at it). This hasn't seemed to fix the issue. Now, if it were just any fan, I would probably just replace the fan - they're relatively cheap after all. However, this is a special fan. Aside: For what its worth, I feel bad that the graphics card blocks part of the fan, but it is the only slot the graphics card fits, so I had no choice. After pulling out my motherboard user guide, it looks like this is a fan placed directly on top of the chipset. To be perfectly honest, I have no clue what the purpose of the chipset is - but it sounds important. After some quick research, I see that it is responsible for providing the bridge between my CPU, RAM and graphics, among other things. Just a quick search at Newegg tells me that chipset fans can be purchased at pretty reasonable prices (< 20 dollars). Is it practical to replace this fan? It is an old computer as computers go and I wouldn't be terribly upset to upgrade the motherboard and processor, so perhaps this is a sign. Hardware Specs: Motherboard: Asus A8N-E Chipset: NVIDIA nForce4 Ultra

• Proper 16:9 video size for non-HD 4:3 video (for youtube/vimeo)

  - by Xeoncross

  Since High Definition video came out on all the online sites it has changed the default aspect ratio of the player from 4:3 to 16:9. This means that for people posting SD video you have to resize some of your videos to get them to fit right. For example, NTSC DVD quality (aka 480i/p) is 720x480 pixels (width x height). However, low-end High Definition (720i/p) is 1280x720. Resolution Chart Anyway, now that the video players are built for HD you will find that uploading standard quality videos will result in videos that are "letter boxed" which means they have extra black bars on the top and bottom (or sides). Correct me if I'm wrong, but in order to get a 720x480 video to fit a box that is designed for HD the best practice would be to crop some of it off so that it fits as 720x404 since: 16/9 = 1.78 (1.7777777777778) 720/405 = 1.78 405x1.78 = 720.9 The same would stand for 640x480 (old TV quality) video that would need to be 640x360 correct? I'm asking because I'm not sure about all this and whether this is the proper way to fix these letter-boxing/display problems.

• Linking to a chat room via XMPP: URI

  - by Coderer

  I found out how to link directly to a chat room on a Jabber conference server -- it took a bit of digging, and I wound up actually looking at the spec before I was sure I was doing it right. I confirmed here, so I'm pretty sure I've got it. The results, though, are puzzling. If I click a link of the style xmpp:[email protected] I get a new chat session with user "dude" at example.com, as expected. If I tack on a nonsense query (xmpp:[email protected]?foobar), it's ignored, which is what the spec says should happen. However, if I use xmpp:[email protected]?join, as in the link above, nothing happens. I dug a little deeper, and found out that on my (Linux) system, xmpp URIs are handled via purple-url-handler, so I dropped to a terminal and ran it manually. The result was that any xmpp URI ran fine except one that includes a ?join query. The ?join query results in a dbus crash, pointing specifically to line 2356 of dbus-message.c -- a little Googling suggests this probably is dbus's less-than-elegant way of telling me that somebody is using dbus incorrectly. Am I crafting my link correctly? Is this an OS or maybe application issue? Does this work on other platforms / browsers / etc? More importantly, is there any easy way to fix it?

  I had problem with Windows 8.1 high Disk usage so in order to solve , searched forums. A voted answer suggested to use CHKDSK command as follow: run command prompt and as administrator type code snippet below: CHKDSK /f /v /b C: (I can not remember accurately) CHKDSK printed : can not run CHKDSK right now , would you like to schedule C drive to be checked next time windows starts? (Y/N) my response was "Y" ,please ! Following this suggestion not only didn't solve my problem as expected but also added another one ! The next time system booted, after windows authentication I just could see a black screen and mouse pointer. So I force shut downed the system and tried to start windows again. This time , windows got stuck in Scanning and Repairing on 22% for around 3 hours so I got tired and forced shut downed again. is CHKDSK source of Scanning and Repairing problem or they are discrete ? is there any hope to overcome this problem without re-installing windows ? can any one else run CHKDSK on newer versions of windows without problem? is CHKDSK effective but inefficient ?(it finally get to end but will take a long time) If yes, how much time does it take? I also have Linux Ubuntu 14.04 installed along side windows.

• How to restore broken Ethernet functionality on Mac G5 running Mac OS 10.4.11 (Tiger)

  - by willc2

  I had a disk error that rendered my Mac unbootable. I repaired it with Tech Tool 4, but now networking does not work. Network Preferences reports that my Ethernet cable is unplugged. I know this is bogus because when I boot from an emergency partition, networking works correctly. Furthermore, wireless networking is also broken, which I tested with a known-good Wi-Fi dongle. Whenever I try to change Network Port Configurations by creating a New or Renaming an existing one, example: I get this message in the console: Error - PortScanner - setDevice, device == nil! Error - PortScanner - setDevice, device == nil! In sets of two as shown. When I try to invoke the Network Diagnostics app, it immediately crashes. My first thought is to reinstall Tiger with the Archive and Install method so I don't have to reinstall all my applications but I have lost my Tiger installer disk. My next thought is to buy Leopard for $107 on Amazon. If there is any way I can just repair my Tiger install I would be happy to save that money, though. This is not my main machine and I am loathe to put more money into it. How can I recover my network functionality? UPDATE: I found my Tiger install disk and tried an Archive and Install. It failed with an unhelpful error message along the lines of "Can't install, try again". I tried again but had the same error. My guess is, some corrupt or missing file in my User folder is preventing migration. I have a backup created with Super Duper that is a bit out of date but will startup the machine (with functional networking). I would love to just copy over the file(s) that got messed up but I don't even know where to look. What is the likely location of the System files that would cause the aforementioned symptoms?

• Ubuntu 12.04 compiz - disable all compiz plugin - empty screen

  - by gotqn

  A lots of thanks to terdon who spent so many time on this and finally solve the issue. A friend of mine has installed on my new machine Ubuntu 12.04 (I have always been windows user and have no experience with Linux). I started to watch some tutorial about how to make 'Rotated Cube' using 'Compiz',but the cube appears in the form of a list (only two slides). I have thought this could be result of my video cards (only two - one from the processor and one from the motherboard) and they can not support this options. Anyway, I have decided to disable all compiz plugins and options because my friend has set some, and I started to think there is some misunderstanding between the plugins. After, that I got only empty screen(no menu, no icons, anything) and can do nothing. How to fix this? EDIT: When I remove the compiz stuffs (from the console), the menu is shown again. Then I install the compiz again (some of the effect are still not working). After restart or log out/in the menu is hidden again. I suppose that there are some settings that I've broken but they are saved somewhere in the system and remove the compiz do not deleted them and as a result they are activated after compiz is installed again and the PC is restarted?

• Mapped networkdrive on logout

  - by Robuust

  I'm using a script to keep a mapped networkconnection alive, but ofcourse the mapped connection is gone when I logout. The point is now, that I'm running this on Windows Server 2008 R2, where I use remote desktop to login on the administrator account. However, it should remain logged in and not remove the mapped connection as this script takes care of not logging out on MS office 365 sharepoint. Is there a way to keep the mapped networklocation (L:) available after logout? So the script can run to remain the connection? # Create an IE Object and navigate to my SharePoint Site $ie = New-Object -ComObject InternetExplorer.Application $ie.navigate('https://xxx.sharepoint.com/') # Don't need the object anymore, so let's close it to free up some memory $ie.Quit() # Just in case there was a problem with the web client service # I am going to stop and start it, you could potentially remove this # part if you want. I like it just because it takes out a step of # troubleshooting if I'm having problems. Stop-Service WebClient Start-Service WebClient # We are going to set the $Drive variable here, this is just # going to tell the command what drive letter to map you can # change this to whatever you want (if you change it to a # drive that is already mapped it will overwrite it, so be careful. $Drive = "L:" # You can change the drive destiniation to whatever you want, # it has to be a document library or folder of course. $DrvDest = "https://xxx.sharepoint.com/files/" # Here is where we create the object to map the network drive and # then map the network drive $net = New-Object -ComObject WScript.Network; $net.mapnetworkdrive($Drive,$DrvDest) # That is the end of the script, now schedule this with task # scheduler and every so often and you should be set.

• Dell PowerEdge 1600SC Server won't boot from Fedora 12 DVD because of CD only drive.

  - by studiohack23

  Dell PowerEdge 1600SC Server won't boot from Fedora 12 DVD in the drive because it only supports CDs as I found out after the fact. I'm a complete novice @ servers, so if you need more detail, let me know, and I'll try to provide it. This server is around 4-6 years old. it has "PXE" boot, not sure what that means? This particular server has 3 RAID hard drives. As far as I know, they have all been wiped. I looked up the service tag on Dell, and it has: Compact Disk Drive, 650M, I Internal, Half Height, 48X, BlackHitachi LG Data Storage as its CD drive. Thus, the CD drive does not support DVDs, so installation will have to be via a live CD. However, I'm trying to put Amahi Home Server (http://www.amahi.org/), and Live CD/USB stick installs are not recommended unless one is an expert Linux user. any suggestions as to how to get around this? PROBLEM SOLVED! THANKS for all the help!

• Handle Sysinternals software does not accept -c parameter

  - by Alex

  I am trying to close a handle to a locked file in Windows, using Sysinternals Handle software (http://technet.microsoft.com/en-us/sysinternals/bb896655). First I search for opened handle: handle.exe "C:\Temp" It issues me the following: Far.exe pid: 1144 type: File 2E8: C:\Temp Far.exe pid: 1144 type: File 3A8: C:\Temp Next I run handle.exe with -c parameter. However, whichever number I enter, it does not do anything. I have tried both: 1144, 2E8, 3A8 and 1144 in hex (478) as the software help says it accepts PID in hexademic. Whatever I enter, it just issues the following: Handle v3.46 Copyright (C) 1997-2011 Mark Russinovich Sysinternals - www.sysinternals.com usage: handle [[-a [-l]] [-u] | [-c <handle> [-y]] | [-s]] [-p <process>|<pid>] [name] -a Dump all handle information. -l Just show pagefile-backed section handles. -c Closes the specified handle (interpreted as a hexadecimal number). You must specify the process by its PID. WARNING: Closing handles can cause application or system instability. -y Don't prompt for close handle confirmation. -s Print count of each type of handle open. -u Show the owning user name when searching for handles. -p Dump handles belonging to process (partial name accepted). name Search for handles to objects with <name> (fragment accepted). No arguments will dump all file references. What am I doing wrong?
