• How can I tell what user account is being used by a service to access a network share on a Windows 2008 server?

  - by Mike B

  I've got a third-party app/service running on a Windows 2003 SP2 server that is trying to fetch something from a network share on Windows 2008 box. Both boxes are members of an AD domain. For some reason, the app is complaining about having insufficient permissions to read/write to the store. The app itself doesn't have any special options for acting on the authority of another user account. It just asks for a UNC path. The service is running with a "log on as" setting of Local System account. I'd like to confirm what account it's using when trying to communicate with the network share. Conversely, I'd also like more details on if/why it's being rejected by the Windows 2008 network share. Are there server-side logs on 2008 that could tell me exactly why a connection attempt to a share was rejected?

• Merit and demerits for various Linux fiberchannel multipath options

  - by wzzrd

  On our Linux servers, we currently use HPs qla2xxx drivers, because it has multipathing (active/passive) built in. The are, however, various other options, like Red Hats device-mapper-multipath with the stock qla2xxx drivers (multibus and failover) and things like SecurePath and PowerPath (both of which can do trunking, iirc). Can someone tell me what the merits and demerits of the various options are (if I can ask such a question), besides the obvious fact that the {Secure,Power}Path options cost vast amounts of money? I'm mainly interested in the freely available options, like HPs qla2xxx vs. Red Hats multipathd and possible other open source solutions, but I would like to hear good reasons to go for the commercial solutions too. UPDATE: I'll be benchmarking various options the coming few days (the average of 10 runs of iozone for each option (options being native qla2xxx failver, native qla2xxx multibus, HP qla2xxx failover)). I'll post a summary of results here for those interested.

• Understanding HTTP Cookies in Indy 10 for Delphi XE2

  - by Jerry Dodge

  I have been working with Indy 10 HTTP Servers / Clients lately in Delphi XE2, and I need to make sure I'm understanding session management correctly. In the server, I have a "bucket" of sessions, which is a list of objects which each represent a unique session. I don't use username and password to authenticate users, but I rather use a unique API key which is issued to a client, and has an expiration. When a client wishes to connect to the server, it first logs in by calling the "login" command, which is a path like this: http://localhost:1234/login?APIKey=abcdefghij. The server checks this API Key against the database, and if it's valid, it creates a new session in the bucket, issues a new cookie (unique string), and sets the response cookies with Success=Y and Cookie=abcdefghij. This is where I have the question. Assuming the client end has its own method of cookie management, the client will receive this login response back from the server and automatically save the cookies as necessary. Any future request from the client to the server shall automatically send along these cookies, and the client side doesn't have to necessarily worry about setting these cookies when sending requests to the server. Right? PS - I'm asking this question here on programmers.stackexchange.com because I didn't see it fit to ask on stackoverflow.com. If anyone thinks this is appropriate enough for stackoverflow.com, please let me know.

• copSHH how to restrict user from going back from there main root

  - by minus4

  I have installed SFTP on a windows servers using copSSH and all is good and it works well however you can go back from the main root. For example when i use C:\copSSH\home{username} as that user i can go back into copSSH and into them directories too. And I have a user setup to actually be C:\inetpub\wwwroot but that user can go into the system and everything i have this set as my path /cygdrive/c/inetpub/wwwroot It would be ideal if the user could only go forward from the start directory, rather than out and about there is no write ability but there is read and download....... thanks

• `which python` points to the python I want, but `python` runs the wrong version

  - by tramdas

  I want to use python24 provided by ports, so I've installed it, and python_select -s shows that the version I want is indeed selected. Running which python gives /opt/local/bin/python, and running /opt/local/bin/python gives me the version I want. However when I run python from the shell, I get the /usr/bin/python version instead. I don't have a python alias. Here's the situation in a nutshell: I believe the path is set up sensibly, and which python seems to confirm this. alias only returns 1 entry, which is something unrelated to this. Nevertheless, running python from the bash shell gives me the wrong python! I'm kind of stumped! What am I overlooking?

• Configure SQL Server to Allow Remote Connections

  - by Ben Griswold

  Okay. This post isn’t about configuring SQL to allow remote connections, but wait, I still may be able to help you out. "A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server)" I love this exception. It summarized the issue and leads you down a path to solving the problem.  I do wish the bit about allowing remote connections was left out of the message though. I can’t think of a time when having remote connections disabled caused me grief.  Heck, I can’t ever remember how to enable remote connections unless I Google for the answer. Anyway, 9 out of 10 times, SQL Server simply isn’t running.  That’s why the exception occurs.  The next time this exception pops up, open up the services console and make sure SQL Server is started.  And if that’s not the problem, only then start digging into the other possible reasons for the failure.

• Recovering drivers from previous installation?

  - by Walkerneo

  Yesterday I bought a new computer and I've been setting it up since this morning. The hard drive came with windows 7 home premium (x64) installed, but I decided to instead install windows 7 ultimate (x64) - this is what I'm currently using. Unfortunately, there were some drivers that were installed that I need in this installation. I only notice because the computer doesn't have the ethernet drivers, so I'm only able to connect to the internet via wireless. There are other drivers missing as well, but I'm not yet seeing the effects. I still have the Windows.old folder with the previous installation, which has the drivers. Is there any way to copy the necessary ones over? I tried the options for updating driver software through device manager with the path set to System32\drivers of the old installation, but it didn't find anything.

• What is the best strategy for transforming unicode strings into filenames?

  - by David Cowden

  I have a bunch (thousands) of resources in an RDF/XML file. I am writing a certain subset of the resources to files -- one file for each, and I'm using the resource's title property as the file name. However, the titles are every day article, website, and blog post titles, so they contain characters unsafe for a URI (the necessary step for constructing a valid file path). I know of the Jersey UriBuilder but I can't quite get it to work for my needs as I detailed in a different question on SO. Some possibilities I have considered are: Since each resource should also have an associated URL, I could try to use the name of the file on the server. The down side of this is sometimes people don't name their content logically and I think the title of an article better reflects the content that will be in each text file. Construct a white list of valid characters and parse the string myself defining substitutions for unsafe characters. The downside of this is the result could be just as unreadable as the former solution because presumably the content creators went through a similar process when placing the files on their server. Choose a more generic naming scheme, place the title in the text file along with the other attributes, and tell my boss to live with it. So my question here is, what methods work well for dealing with a scenario where you need to construct file names out of strings with potentially unsafe characters? Is there a solution that better fills out my constraints?

• Apache not running from rc.d on FreeBSD

  - by Oksana Molotova

  I'm using FreeBSD 8.3 and Apache 2.2. I didn't install Apache from ports, instead compiled it from source because I wanted to move the binary and configuration to a different path (I'm centering all of the major production daemons and their configurations in a single place). In any case, I based the /usr/local/etc/rc.d/apache22 file on one from a different server where it was installed from ports, I only modified the binary and config paths within. I can manually execute it with /usr/local/etc/rc.d/apache22 start, however even with apache22_enable="YES" in /etc/rc.conf it fails to start. All permissions and ownership are identical to the other server where it works. What am I missing and is there a way to debug this kind of thing?

• Shockwave Flash crashes with Chromium and Firefox

• How to efficiently permanently redirect 150.000 images?

  - by Fabio Spampinato

  For SEO purposes I need to rename around 150.000 images, then I'd like to permanently redirect the previous url locations requests to the new locations. The current url to every image is something like: website.com/something/unique_id/filename.jpg And I want to redirect them to: website.com/something/unique_id/new_filename.jpg I can only think about 2 options: 1) Create an enormous list of redirects to include into my nginx's conf file. 2) Redirect those requests to something like "website.com/new_location/unique_id" that will redirect the request again to the new path. There are other, better, options? Should I avoid multiple 301 redirects? Will crawlers downgrade my rankings because of multiple redirects?

• Cannot set MemOpMode or ProcVirtualization with syscfg.exe

  - by EGr

  When attempting to set MemOpMode or ProcVirtualization with syscfg.exe, I get the following error: C:\Users\EGr>syscfg --MemOpMode=AdvEccMode System Services or CSIOR disabled In the past, I have been told that this can be resolved by forcefully reinstalling the Dell Lifecycle controller firmware, and then trying again; however, I cannot find my notes on how to do that. Has anyone ever run into this issue, and does anyone know how I can fix it? If it is possible to forcefully reinstall the firmware, how would I do that? I've tried running the installer, but it fails after running for ~2 min. I believe there is a way to fix this as well, by adding/modifying a registry value at HKLM\System\Control\CurrentControlSet\Services\IPMIDRV (that might not be the correct path, but I know it is IPMIDRV). Is this a common issue? What is the actual cause of it?

• /planes and /clubs or /wiki/planes and /wiki/clubs

  - by Jelmer

  I am currently working on a nice application about which I can't share all the details, but it will have some sort of a wiki part. In this wiki, you will be able to change the planes as well as the clubs, maybe in the future it will be possible to change the countries and manufacturers as well. But I have to think about this and I have to check how good this is. But, you will understand that it has to be expendable! That is really important. Use the planes controller with a edit page and the same for the clubs Route the planes and clubs controller to the wiki controller, so we have 1 nice "path" to edit this stuff. I want to have it called wiki that is for sure. Because that is what it is, but I am storing the planes and clubs data in its down table in my database. I think that is kinda obvious since it has to be maintainable. Right now you could edit a plane via the url: example.com/wiki/planes/edit/Duo_Discus.html Do you think that is better than example.com/planes/edit/Duo_Discus.html since it is easy to understand for the user, that he is working in the wiki instead of in the planes ? Or do you think this will break the user experience?

• Running Mac OSX 10.6 my users home directory is wrong

  - by Erik Miller

  Somehow my home directory on my mac machine has been changed and I'm not sure how to go about changing it back, I'm more of a linux guy and mac has some other mechanism for storing that information. Basically when I log into the machine normally than start a terminal window. I start in the /Users/erik_miller directory, which is my home directory, but when I run some this like cd ~ The machine tries to change to /Users/erik_miller. Yes, the same path with a period on the end. I can change my $HOME environment variable for the session, but the next time I start the machine it reverts. So, I think if I can find where that information is stored I can just change it there and hopefully all will be well.

• Keyboard locking up in Visual Studio 2010, Part 2

  - by Jim Wang

  Last week I posted about looking into the keyboard locking up issue in Visual Studio.  So far it looks like not a lot of people have replied to provide concrete repro steps, which confirms my suspicion that this is somewhat of a random issue. So at this point, I have a couple of choices.  I can either wait for somebody in the community to provide a repro of the problem that I can reliably run into, or I can do the work myself. I’m going to do both, so while I’m waiting for more possible bug reports, I’m going to write a tool that models the behavior of a typical Visual Studio user and use that to hopefully isolate the problem. I’ve chosen to go with this path since given the information in the bug reports, it seems people hit the issue with many different configurations in many different scenarios.  This means that me sitting down without any solid repro steps is likely not going to be a good use of time.  Instead, I’m going to go with a model-based testing approach where I will define a series of actions that a user in VS can do, and then proceed to run my model.  I’ll let you guys know how this works out for isolating bugs :) I’m using an internal tool for the model engine and AutoIt for the UI automation (I want something lightweight for a one-off).  One of the challenges will be getting feedback: AutoIt is great at driving, but not so great at understanding what success and failure means.

• BizTalk: mapping with Xslt

  - by Leonid Ganeline

  BizTalk Map Editor (Mapper) is a good editor, especially in the last 2010 version of the BizTalk. But still sometimes it cannot do the tasks easily. It is time for the Xslt code, It is time to remember that the maps are executed by the Xslt engine.  Right-click the Mapper Grid (a field between the source and target schemas) and choose Properties /Custom XSLT Path.  Input here a name of the file with Xslt code. Only this code will be executed, forget the picture in the Mapper, all those links and functoids.  Let’s see the real-life example. There are two source Addresses. One is on the top level and the second is inside the Member_Address record with MaxOccurs=* . The target address is placed inside the Locator record with MaxOccurs=*. The requirement is to map all source address to the one target address structure. The source Xml document looks like: The result Xml should be like this: Try to do this mapping with the Mapper and you will spent good amount of time and the result map would be tricky. If we use the Xslt code, the mapping will be simple and unambiguous, like this: Simple, elegant.

• My sendmail sends spam and I can't identify which script sends it

• KVM CLI install for CentOS 6.3 defaults to Minimal Install

  - by i.h4d35

  So I now I've installed KVM (and its associated tools and packages- libvirt, VMM etc.). On the GUI (i.e using the VMM), installation works as its supposed to. However, when I try to create a VM using the command line interface, the OS (I am working with CentOS 6.3) defaults to a Minimal Install instead of giving me options to choose from at the time of installation. I am trying to install using the following command: virt-install \ --connect qemu:///system \ --virt-type kvm --name testVM2 \ --ram 512 --disk path=/var/lib/libvirt/images/testVM2.img,size=8 --vnc \ --cdrom /media/db18de8e-0853-49fb-80de-5c794d58a46f/CentOS-6.3- x86_64-bin-DVD1.iso \ --network network=default Specifying the OS-type or the OS-variant parameters doesn't make a difference. Is there something that I am missing out on or some other parameter that I must specify? Thanks in advance.

• What changes can be made to a Microsoft Account using net user on Windows 8?

  - by nhinkle

  In Windows 8, you can log on with a local account or with a Microsoft Account. Both types show up in the Users control panel, but there are different options that you can change for each type. An administrator can change basically any aspect of a local user - name, password, access level, etc. For a Microsoft Account, you can only change the access level (admin/standard) or remove the account. From the command line though, there don't appear to be any restrictions on what you can do a Microsoft Account. Using the net user tool or the Local Users and Groups MMC snap-in, it looks like an administrator would be able to change the password, display name, profile path, etc. of Microsoft Accounts (as well as local accounts of course). Will these commands actually work when applied to a Microsoft Account? Will using them in some way break the link to the Microsoft Account, or will nothing happen at all? I'm hesitant to test since I don't want to mess up my account permanently.

• How to fix Failed to initialize Windows Azure storage emulator error

  - by ybbest

  When you press F5 to start debugging Azure project, you might get the following exception: If you go to the Output windows, you will see the detailed error message below: Windows Azure Tools: Failed to initialize Windows Azure storage emulator. Unable to start Development Storage. Failed to start Development Storage: the SQL Server instance ‘localhost\SQLExpress’ could not be found. Please configure the SQL Server instance for Development Storage using the ‘DSInit’ utility in the Windows Azure SDK. This is because by default, Azure uses the SQLExpress to start Development Storage. To fix this you can do the following: You need to open command prompt, and navigate to C:\Program Files\Windows Azure SDK\v1.4\bin\devstore (depending on your Azure version, the file path is slightly different.) Next, run DSInit /sqlInstance:. (. Means the SQL Server use the default instance, if you have name instance, you need to change. to the name of the SQL Server) After a short while, you should see the following windows showing the configuration succeeds. You can download a batch file here. References: http://msdn.microsoft.com/en-us/library/gg433132.aspx

• OCS 2007 Access Edge Server Certificate issue

  - by BWCA

  We are currently building additional OCS 2007 R2 Access Edge Servers to handle additional capacity.  We ran into a SSL certificate issue when we were setting up the servers. Before running the steps to Deploy an Edge Server, we successfully imported our SSL certificate that we use for external access on all of the new servers.  After successfully completing the first three Deploy Edge Server steps one one of the new servers, we started working on Step 4: Configure Certificates for the Edge Server.  After selecting Assign an existing certificate from the common tasks list and clicking Next to select a certificate, there were no certificates listed as shown below.   The first thing we did was to use the Certificates mmc snap-in to review the SSL certificate information.  We noticed in the General tab that Windows does not have enough information to verify this certificate and in the Certification Path that the issuer of this certificate could not be found for the SSL certificate that we imported successfully earlier.     While troubleshooting, we learned that we could not access the URL for the certificate’s CRL to download the CRL file due to restrictive firewall rules between the new OCS 2007 R2 Access Edge Servers and the Internet. After modifying the firewall rules, we were able to download the CRL file and when we reran Step 4 to assign an existing certificate, the certificate was listed.

• WebDAV "PROPFIND" exception in IIS due to network share?

  - by jacko

  Hi all, We're finding continuous exceptions in our event viewer on our live box to the following exception: [snippet] Process information: Process ID: 3916 Process name: w3wp.exe Account name: NT AUTHORITY\NETWORK SERVICE Exception information: Exception type: HttpException Exception message: Path 'PROPFIND' is forbidden. Thread information: Thread ID: 14 Thread account name: OURDOMAIN\Account Is impersonating: True Stack trace: at System.Web.HttpMethodNotAllowedHandler.ProcessRequest(HttpContext context) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) Other Specs: Windows Server 2003 R2 & IIS 6.0 We've narrowed it down to occuring when people try to access shares on the box from within the network, and have discovered (we think) that its due to the WebDAV web services extension being previously disabled by past staff. The exceptions are being thrown when trying to access directories that are virtual dirs in IIS, and plain old UNC network shares What the implications for enabling the WebDAV extensions on our live web server? And will this solve our problems with the exceptions in our event log?

• How to change controller numbering/enumeration in Solaris 10?

  - by Jim

  After moving a Solaris 10 server to a new machine, the rpool disk is now c1t0d0. We have some third party applications hard coded for c0t0d0. How can I change the controller enumeration on this machine? There is no longer a c0. I've tried rebuilding the /etc/path_to_inst, but the instance numbers don't seem to match up with the controller numbers. Also, it's not clear if i86pc platforms use this file. I've tried devfsadm -C to clear the dangling links, but I'm not sure how to cause devfsadm to start numbering from 0 again (or force certain devices in the tree to a specific controller number). Next I am going to try to create the symlinks manually in /dev/dsk and rdsk to point to the correct /devices. I feel like I am going way off path here. Any suggestions? Thanks
