• How to safely remove a device blocked by the System process with a handle on \$Extend\$RmMetadata\$Txf

  - by Heinzi

  I have an external HDD which I would like to "safely remove". Unfortunately, my system (Windows 7 x64) complains that "the device is currently in use". Using Process Explorer I discovered which process is holding a handle on the device: Obviously, System is not a process that I can just kill and be done with it. I've done a bit of research and this seems to be a common problem, but no solution has been found so far (except for rebooting the machine, which I'd like to avoid if possible). Is there any solution to this problem that I've missed?

• recover files from encrypted home folder

  - by maskiepop

  I can't seem to find the answer to my questions -- hence my posting this here. 1) I have encrypted my home folder in LinuxMint 15 Cinammon x64. If I create images of LM's partitions via fsarchiver, how do I go about selectively restoring home folders, and files from the FS images? 2) I haven't done this yet; but can I restore another users home folder into another user; both unencrypted. Is that a fairly common thing to do in Linux/ubuntu? I mean is the process fairly straightforward? What if the home folder I want to copy over to another user is encrypted? Thx

• How to forward UDP Wake-on-Lan port to broadcast IP with IPTABLES?

  - by Nazgulled

  I'm trying to setup Wake-on-Lan for some of the LAN computers at home and it seems that I need to open a UDP port (7 or 9 being the most common) and forward all requests to the broadcast IP, which in my case is 192.168.1.255. The problem is that my router does not allow me to forward anything to the broadcast IP. I can connect to my router through telnet and it seems this router uses IPTABLES, but I don't know much about it or how to is. Can someone help me out with the proper iptables commands to do what I want? Also, in case it doesn't work, the commands to put everything back would be nice too. One last thing, rebooting the router will keep those manually added iptables entries or I would need to run them every time?

• Why can't the Adobe Flash player send key strokes it doesn't handle to the browse in which it is run

  - by jim.e.clark

  I'm a heavy web user that uses the address bar constantly while browsing the web. I often use Ctrl + T to open a new tab or Ctrl + D to move focus to the address bar so it is very annoying that these shortcut keys do not work when a Flash object has focus on the active browser tab. I would happily give up all keyboard handling in the Flash Player in exchange for having keystrokes sent to the browser. In fact, as someone who has worked in software development for over 15 years it is hard to believe that Flash doesn't pass common browser shortcut keys to the browser or have an option to do so. So my question is this: Am I missing some option, some Flash shortcut key or some Firefox add-on that will alleviate my suffering?

• What tools exist for generating "ASCII Tables", if any?

  - by Billy ONeal

  Consider a block like the following: +-----------------------------------+--------------------------+ | In Baseline | Not in Baseline | +---------------+===================================+==========================+ | In Parent # Do Not Report | Mark ACE as AlwaysReport | +---------------+-----------------------------------+--------------------------+ | Not In Parent # Iff parent depth > baseline depth | Report Always | +---------------+-----------------------------------+--------------------------+ I have seen tables like this used quite frequently. For instance, in Requests for Comments (RFC) documents, the standard format of the document is the text format. Another common case is embedding a small table like this into comments of source code. Are there tools which can take a quick and dirty representation of this in Excel, or possibly some textual format, and format it as a table like this?

• Mutli-processor workstation as a workstation/server

  - by posdef

  I work in a research institute and a number of programs we use are computationally intensive (I actually wrote one of them). Right now we have one computer that is dedicated for one of these programs (with local accounts only, as in users physically sitting in front of that pc) and the other programs are run on individual workstations assigned to people. I have been looking around to common brands such as Dell and HP, for a some sort of a small/medium scale server, which can be used as a workhorse by sending tasks remotely. It appears as if there is nothing in between workstations with one 6-core processor and a bunch of extras (like fancy graphics etc) and rack mount servers with ridiculous amount of RAM and HDD expansion capabilities but still relatively little number of processors/cores. I wonder if what I am looking for is such a small niche product? Are there other solutions that I might not be aware of? Does anyone know of a multi proc- multi-core workstation/server that is still within the reasonable

• Can I repair a short circuiting problem in a Dell Inspiron 6000 that occurs when it is picked up?

  - by jim.e.clark

  I have a couple of Dell Inspiron 6000 notebooks that work perfectly fine unless you pick them up by one corner (as most people would). When you lift the notebook it flexes slightly and the notebook shorts out. Sometimes even a gentle bump will cause this to happen. So far the notebook always starts back up without issue, but this behavior is...inconvenient. It occurred to me that someone familiar with the innards might be able to suggest a little MacGyver fix for this. A little electrical tape in the right spot or something like that. Or perhaps this is a common problem and the answer is here, waiting for me to stumble on the correct keywords. I would appreciate any suggestions Note: It is probably worth mentioning that I have disassembled a Dell notebook before to replace a bluetooth card so I comfortable opening up the systems.

• How to avoid Master Browser errors, MRxSmb Event ID 8003?

  - by Sanoj

  I have a domain with Windows SBS 2003 as domain controller. It's very common to get Master Browser errors in the logs, MRxSmb Event ID 8003. How can I avoid that? What have I done wrong? I know how to solve this: Stop the Computer Browser service on clients, but I don't know how to avoid this since the problem comes back every time I add a new client and I forget to stop the Computer Browser service. Error message: The master browser has received a server announcement from the computer [computer] that believes that it is the master browser for the domain on transport NetBT_Tcpip_{#######-####-####-#. The master browser is stopping or an election is being forced. Is there an configuration of the server to avoid this problem?

• PHP-FPM for nginx on debian

  - by Jelko

  What is the preferred/recommended way of installing php-fpm on debian for use with nginx? I read about a "php5-fpm" package everywhere, but it's not available in the official debian repos any more. The PHP-FPM website (http://php-fpm.org/download/) says that fpm is now included with the php core. Is it enough to install "php5-common" then? Where are the config files, though? Other people recommend to install the current version of php and php-fpm from dotdeb.org. The versions provided there are generally more up to date. But is it secure? Is this a good repo to use in a production environment? I would appreciate any advice.

• Configuring HAProxy with memcache with failover

  - by Lawrie Matthews

  I'm configuring a new set of servers for an existing Wordpress site, and it's been requested that memcache be available and made more resilient. The idea proposed is to have HAProxy send requests to one of the two servers; if that memcache instance is inaccessible, then it should switch to the second, but should not switch back to the first if it comes back up unless the second is then unavailable. This doesn't appear to be a particularly common use case and I've not found much along these lines except to possibly set up the first node with an enormous rise value, such as: server server1 10.112.58.16:11211 check inter 5s fall 3 rise 99999999 server server2 10.112.58.19:11211 check backup which falls over as expected when server1 is unavailable. It won't ever fall back to server1, though, even if server2 goes offline. Can this be made to work?

• Export SharePoint Wiki to PDF from the Command Line

  - by Wyatt Barnett

  We use a SharePoint wiki* at the office to serve as a knowledgebase for our IT operations. Recently we went through a disaster recovery exercise where we realized we had a key hole in our plans: how do you restore the services if your instruction manual is down because some services are offline? Anyhow, we did realize that the wiki angle was definitely something we wanted to keep, but rather that we should explore a way to create offline backups of the wiki which could be easily read using common software we should be able to setup without any knowledge from the wiki. So, does anyone know of a good utility that can take a SharePoint wiki and dump it to PDF/Word/RTF/[INSERT HUMAN FRIENDLY FORMAT] easily from the command line? *-Yes, there are better solutions out there. But this was easy and used existing infrastructure and generally does what we need it to do.

• Oracle tuning optimizer index cost adj and optimizer index caching

  - by Darryl Braaten

  What is the correct way to set the optimizer index cost adj parameter for Oracle. As a developer I have observed huge performance improvements as this parameter is lowered. Common queries are reduced from 2 seconds to 200ms. There are lots of warnings on the net that lowering this value will cause dire issues with the database, but no detail is given on what will start going wrong. I am currently only seeing only an upside, much improved application performance and no downside. I need to better understand the possible negative repercussions of adjusting these parameters.

• Warning: DocumentRoot * does not exist on Centos 6

I think, maybe this error about SeLinux and disable it. But not working. Still same error. How can I fix this problem?

• Getting error 0x000003eb when installing DDK sample printer drivers

  - by Andy

  I've got a development machine, which has been severly abused when it comes to installing and removing printer drivers. I'm now at the stage where I want to install some sample printer drivers from the DDK (WDK), but unfortunately I get the message 'Unable to install printer. Operation could not be completed (error 0x000003eb). So I tried installing the same printer driver built from the DDK in a clean Win 7 x64 VM, and it works, so the only thing I can imagine is that the driver store or driver folder may be slightly corrupt from the many previous printer drivers I had installed. So my question is, is there anyway I can clean my system of old printer drivers / file? Or any repair functionality in windows that may replace the common windows printer drivers?

• What are the consequences of giving an AD domain differing NetBIOS and DNS names?

  - by Newt

  In the past, when creating AD domains, I've used the common convention of using a sub-domain of the company's publicly registered domain name, e.g "corp.mycompany.com" or "int.mycompany.com". I've always accepted the default NetBIOS name when running DCPromo, for fear that creating a NetBIOS name that differs from the sub-domain may cause complications. I've recently been doing a bit of research on the consequences of providing an alternate NetBIOS name. The main reasons behind this are: The NetBIOS name isn't particularly descriptive or unique to the company Apparently generic NetBIOS names such as "CORP" or "INT" can cause issues when merging IT systems (although I've not had experience with this myself) Providing something "before the slash" that means more to users (less important) In looking at the possible downsides, the only one I can come up with is the disjointed namespace issue when configuring Exchange. Can anybody with more experience than I elaborate on my findings at all? Many thanks

  Hi, im an undergrad student and we have special access to a server. The server is a unix server (dont know the OS or anything.. is there a way to find out? ). we also get a website associated with the server. There is a public_html folder.

So im guessing PHP isnt installed. is there a way to see what "common" languages ARE installed?

• Apache gzip with chucked encoding

  - by hoodoos

  I'm expiriencing some problem with one of my data source services. As it says in HTTP response headers it's running on Apache-Coyote/1.1. Server gives responses with Transfer-Encoding: chunked, here sample response: HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Content-Type: text/xml;charset=utf-8 Transfer-Encoding: chunked Date: Tue, 30 Mar 2010 06:13:52 GMT And problem is when I'm requesting server to send gzipped request it often sends not full response. I recieve response, see that last chunk recived, but then after ungzipping I see that response is partial. So my question is: is it common apache issue? maybe one of it's mod_deflate plugins or something? Ask questions if you need more info. Thanks.

• Cannot connect to xdebug over virtual network - Vagrant Virtualbox

  - by smix96

  I'm trying to set up a development box using Virtualbox / Vagrant / Puppet with the intention of eventually provisioning all my machines up to production. However this is stopping me going forward at the moment. I've installed ubuntu lucid over windows 7. When trying to connect to xdebug by starting a debugging session in eclipse, it hangs at 57% (common in eclipse when it cannot communicate with xdebug). Here is my xdebug.ini and the settings here are appearing in phpinfo(). xdebug.remote_enable=On xdebug.remote_handler=dbgp xdebug.remote_host=192.168.56.1 xdebug.remote_port=9000 I'm now wondering if it's an issue with port forwarding? If eclipse is looking on port 9000, will it find port 9000 on a virtual machine? Any help would be greatly appreciated!

• Windows 7 Service Pack 1 Install Failing

  - by Cu Jimmy

  I am having real trouble updating one of my machines to Win7 Service Pack 1. Its an Asus P5K board with an X9650 Quad Core Extreme chip, which is a less common type of chip. Was wondering if anyone has had issues with this kind of kit or if it may just be the motherboard is a little gone. The error message I get back from Microsoft Update is WindowsUpdate_80091007 and WindowsUpdate_dt000 which are fairly generic errors. Tried installing with the sp1 file based installer and got nowhere. The actual installer crashes with an SP Installer has crashed Its a fresh install on a fully scrubbed drive (an Intel 120GB SSD).

• Mail Server using Postfix

  - by unknown (google)

  I have currently set up my web application on Amazon EC2 server. As a well known fact sending email from EC2 has a problem. As a cheap and long lasting solution instead of using "authsmtp" is it possible to rent a server and use it as a Mail Server? I am currently looking for cheap hosting which will give me root access so that it can be configured and used as a relayhost. I am curently using Postfix as MTA. Has any one implemented this before? I am curious about its feasibility of this solution. I guess common requirements are: Dedicated IP which is not black listed Open relay( open to my Server only) Any Tips for Header configurations to keep the mails out of spam folder. This is like exactly cloning authsmtp for personal use. Any suggestions for other Mail Server software instead of Postfix?

• McAfee Secure Messaging Service / Postini: false positive?

  - by Martin

  Hello, I'm puzzled by this email message that gets quarantined by McAfee Secure Messaging Service (it's based on Postini) for no reason that I can think of. Here are the Postini headers: X-pstn-2strike: clear X-pstn-neptune: 0/0/0.00/0 X-pstn-levels: (S: 0.02932/98.63596 CV:99.9000 FC:95.5390 LC:95.5390 R:95.9108 P:95.9108 M:97.0282 C:98.6951 ) X-pstn-settings: 3 (1.0000:1.0000) s cv gt3 gt2 gt1 r p m c X-pstn-addresses: from [db-null] X-pstn-disposition: quarantine I read the docs (http://www.mcafee-sms.com/webdocs/admin%5Fee%5Fmcafee/wwhelp/wwhimpl/common/html/wwhelp.htm?context=MACAFFHelp&file=header%5Foverview.html#951634) and in short, the x-pstn-settings header tells me that NONE of the filters was triggered, but the x-pstn-levels header tells me that the final score (0.02932) is low enough to classify the email as bulk/spam. Can anyone explain to me why the final score is so low when none of the filters were triggered? Does anyone have any suggestions on how to prevent this from happening? Regards, Martin

• Reverse Proxy Methods for Hosting a Low-Bandwidth Dynamic Website

  - by Casey

  I am building a webcam w/ HTTP server that will be running from a low-bandwith connection. The content on the site will be changing every 5 to 10 minutes. Instead of serving files directly from this connection, are there hosting companies that can act as a reverse proxy for my site? Therefore, if nobody is using the site, the local internet connection remains idle. And if I receive 1000 hits all at the same time, only one HTTP GET is required, and the hosting company (on a fat pipe) continues serving the other 999 requests? This doesn't sound like a very common usage model, but I feel like this would be the optimal solution to my situation.

• NTFS disk mounted as fuseblk in ubuntu 12.10 is very slow and a lot of errors when rsync. Is that not a rare thing?

  - by Pablo Marin-Garcia

  I am having problems with a NTFS disk mounted as a fuseblk in my ubuntu 12.10 through external usb3. When I did a 1.1TB backup with rsync the speed was 1-2MB/s (wiht a ext4 disk speed was 70 MB/s before and after trying the NTFS disk). Also after one hour errors started to appear: rsync: write failed on "xxx": No such file or directory recv_files: "yyy" is a directory #but this file is a FILE not a dir ??!! .... As this is the first time I have mounted the NTFS in linux for heavy usage (the data would be used in windows afterwards), I would like to know if this kind of thinks are common o was only that something became unstable in my system and a simply restart would probably have solved it. This leads me to the these questions: Can I trust fuse for manage NTFS disks? Or is a problem of the NTFS tools in linux not yet totally stables for writing? Do people is still suffering from low performance with fuse-NTFS vs ext4 (in the past I have read about people complaining about this)?

• How do you cache web pages with a personalized header using caching reverse proxy such as Squid, Var

  - by Continuation

  Pretty much every page of my website is dynamically generated. However they don't change that frequently (kinda similar to a forum page). So I'd like to cache them using a caching reverse proxy such as Squid, varnish or Nginx. The problem is that for my logged-in users, each of them will see a personalized header saying "Welcome John Doe. Logout" on the upper right corner of the page (just like serverfault). While users who aren't logged in will see a header that says "Login" instead. So basically even though every user will see the same page in general, they all slightly different version due to that personalized header. Is there any way so that I can cache the "main" part of the page and serve it from cache while generate the personalized header dynamically for each individual user? This must be a very common problem. How is it solved in general?
