• How to perform this Windows 7 permissions change on many files via GUI or command line

  - by hippietrail

  After using my external hard drive on another Windows 7 computer to tweak photos with Windows Live Photo Gallery then upload them to Facebook I found the modified images were now not visible on the original Windows 7 computer. I'm not sure if the things I tried to get it working subsequently changed anything, but I do know this is the sequence of actions that makes the permissions of the modified files match those of the unmodified files: Right click on broken image file, select "Properties" On the "Security" tab press the "Advanced" button In the "Permissions" tab press the "Continue" button with the shield icon on it Tick the box marked "Include inheritable permissions from this object's parent Click the "Remove" button to remove the only current entry "Type: Allow, Name: Administrators (XYZ\Administrators), Permission: Full control, Inherited From: OK on the "Permissions" tab. OK on the "Security" tab. Now this same procedure does not work at the folder level. It results in "access denied" dialogs. I'm looking for some way to perform this exact modification on all the images I edited on the other computer. I'm happy to use the Windows GUI in Explorer or any other included tools. I'm happy to use the Windows command line. I'd prefer not to use a third-party tool since I'd have to be satisfied it's not doing anything else. I'm not looking for a different way to change permissions to other settings to make an external drive full of photos editable on multiple computers. At least not in this question.

• 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.

• How to automate downloading files?

  - by Damon

  I got a book which had a pass to access digital versions of hi-res scans of much of the artwork in the book. Amazing! Unfortunately the presentation of all the these are 177 pages of 8 images each with links to zip files of jpgs. It is extremely tedious to browse, and I would love to be able to get all the files at once rather than sitting and clicking through each one separately. archive_bookname/index.1.htm - archive_bookname/index.177.htm each of those pages have 8 links each to the files linking to files such as <snip>/downloads/_Q6Q9265.jpg.zip, <snip>/downloads/_Q6Q7069.jpg.zip, <snip>/downloads/_Q6Q5354.jpg.zip. that don't quite go in order. I cannot get a directory listing of the parent /downloads/ folder. Also, the file is behind a login-wall, so doing a non-browser tool, might be difficult without knowing how to recreate the session info. I've looked into wget a little but I'm pretty confused and have no idea if it will help me with this. Any advice on how to tackle this? Can wget do this for me automatically?

• How do I fully share a Hard Drive on my Local Network?

  - by GingerLee

  I have 4 computers connected to a router (DD-WRT) My main PC is Windows 7 (Home Premium). This machine has 2 Hard Disks: HD1 is used for my OS and the other (HD2) is used to store files. My 3 other machines are 1. Ubuntu Destop that I use to learn about linux, 2. A Mac OSX laptop, and 3. A netbook running windows 7. How do I easily share HD2 with my other machines? I would like all my machines to have full access & permissions to HD2 however I would like to RESTRICT access to only PCs that are connected to my router (either via LAN and WiFi) --- btw, I know this is not very secure due to WiFi vulnerability , however, I currently MAC address restrict WiFi connections my router. Extra Info: I have already tried to use the Windows Folder Sharing feature: i.e. I right click over the icon of HD2, and click on the Sharing Tab, but in sub-window labeled "Network File and Folder Sharing", the "Share" button is grayed out. I can click on "Advanced Shared" but that just takes me to a screen in which I have to set certain permissions. What is not clear to me is: How do I set a criteria that shares HD2 with all computer connected to my router?

• Need software to convert RAR to ZIP ("store" mode - no compression) * Extract->re-archive changes date/time attributes

  - by Larry78

  I have tried all of the following applications (download.cnet.com - the free ones), and none of them will convert an RAR archive to a ZIP, without compressing the files ("store" mode). 7-ZIP would be fine, too. [The RAR is a "solid" archive with password (I know it), files "stored" - no compression, used WinRAR 3.5.1] PeaZip, 7-Zip, FilZip, TugZip, SimplyZipSE, QuickZip, WinShrink. (A couple of the apps let you try, but the program gives an error - indicating how bad the software is. (Like "unknown header # #.") None of these apps will do the conversion at all. IZArc 4.1 comes the closest. It will convert an RAR to a ZIP, but it compresses the zip. There is a general preference setting to "store" - but it doesn't effect conversions. I don't want to extract the RAR files and re-archive them because I need to preserve the modified/created file attributes. IZArc preserves them, but it compresses the files. WinRAR has the option to convert archives, but I get the error "skipping encryped archive" when I try to convert it. It asks for the password first, and I know it's right because that password opens the archive, and I can read/view all the files in the archive.

• My Hard Drive isn't Working

  - by MeCB

  I never use Safely Remove Hardware with Windows XP. It has been working for me for years with my SD card, mouse, hard drive and memory stick. My hard drive has a USB cable and power cord so I can hook it up to any desktop hard drive. Now my hard drives don't like this and I did not know this till now. I am always careful and to wait till it is all finish accessing the USB before I unplug it. Now three of my hard drives can't be seen by Windows, though the others still work. when I hook it up to another computer it works fine. I use the same USB cable to hook up all of my hard drives one at a time. So my USB cable is good. I think that when I unplugged the hard drive this one time, it had a file it still wanted to see and now only this drive does not work only this computer. Then the same thing happens to my other two hard drive after I used it for a week with the same cables. How can I fix this?

• Adding a hyperlink in a client report definition file (RDLC)

  - by rajbk

  This post shows you how to add a hyperlink to your RDLC report. In a previous post, I showed you how to create an RDLC report. We have been given the requirement to the report we created earlier, the Northwind Product report, to add a column that will contain hyperlinks which are unique per row.  The URLs will be RESTful with the ProductID at the end. Clicking on the URL will take them to a website like so: http://localhost/products/3  where 3 is the primary key of the product row clicked on. To start off, open the RDLC and add a new column to the product table.   Add text to the header (Details) and row (Product Website). Right click on the row (not header) and select “TextBox properties” Select Action – Go to URL. You could hard code a URL here but what we need is a URL that changes based on the ProductID.   Click on the expression button (fx) The expression builder gives you access to several functions and constants including the fields in your dataset. See this reference for more details: Common Expressions for ReportViewer Reports. Add the following expression: = "http://localhost/products/" & Fields!ProductID.Value Click OK to exit the Expression Builder. The report will not render because hyperlinks are disabled by default in the ReportViewer control. To enable it, add the following in your page load event (where rvProducts is the ID of your ReportViewerControl): protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { rvProducts.LocalReport.EnableHyperlinks = true; } } We want our links to open in a new window so set the HyperLinkTarget property of the ReportViewer control to “_blank”   We are done adding hyperlinks to our report. Clicking on the links for each product pops open a new windows. The URL has the ProductID added at the end. Enjoy!

• Using XNA ContentPipeline to export a file in a machine without full XNA GS

  - by krolth

  My game uses the Content Pipeline to load the spriteSheet at runtime. The artist for the game sends me the modified spritesheet and I do a build in my machine and send him an updated project. So I'm looking for a way to generate the xnb files in his machine (this is the output of the content pipeline) without him having to install the full XNA Game studio. 1) I don't want my artist to install VS + Xna (I know there is a free version of VS but this won't scale once we add more people to the team). 2) I'm not interested in running this editor/tool in Xbox so a Windows only solution works. 3) I'm aware of MSBuild options but they require full XNA I researched Shawn's blog and found the option of using Msbuild Sample or a new option in XNA 4.0 that looked promising here but seems like it has the same restriction: Need to install full XNA GS because the ContentPipeline is not part of the XNA redist. So has anyone found a workaround for this?

• How to reload sarg configuration file

  - by black sensei

  I have installed sarg for a while on ubuntu 12.04 and forgotten that I wanted it to generate reports inside /var/www/vhosts/reports.lan/htdocs. I have found out this morning and made the change in the /etc/sarg/sarg.conf. After I have manually run sarg with # sarg-reports today but it generated in the old folder /var/lib/sarg . I know I could do a symbolic link but I was surprised that I could not find a single command to reload or at least restart sarg. Can anyone give me the command to restart or reload it? Thanks

• What's causing Remote Access error 807 using rasdial.exe to connect to a PPTP VPN?

  - by Dylan Beattie

  I'm using rasdial.exe to connect an offsite server to our VPN. Remote box is a Windows 2008 x64 server; the VPN host at this end is a Watchguard Firebox x750e running Fireware 10.2 It connects fine about 20-30% of the time. The rest of the time I get: Remote Access error 807 - The network connection between your computer and the VPN server was interrupted. This can be caused by a problem in the VPN transmission and is commonly the result of internet latency or simply that your VPN server has reached capacity. Please try to reconnect to the VPN server. If this problem persists, contact the VPN administrator and analyze quality of network connectivity. For more help on this error: Type 'hh netcfg.chm' In help, click Troubleshooting, then Error Messages, then 807 The VPN isn't full, and it's 100Mb dedicated fibre on both ends so I can't believe it's a connectivity issue - especially since I'm RDP'ed into the remote box whilst trying to do this! Any bright ideas as to what might be causing the problem? Thanks, Dylan

• rsnapshot intervals in configuration file…

  - by Patrick

  A simple question about rsnapshot. In order to perform daily backups I'm going to add lines to cron in my Ubuntu. Then, why do I have also these lines in the rsnapshot.conf ? ######################################### # BACKUP INTERVALS # # Must be unique and in ascending order # # i.e. hourly, daily, weekly, etc. # ######################################### interval hourly 6 interval daily 7 interval weekly 4 #interval monthly 3 If I use cron, should I disable them ? thanks ps. I've just realized that in the crontab I still have "hourly" and "daily". Should I then uncomment only the one I use in the crontab ? And what's the point to specify hourly if it is already specified in cron ? I'm a bit confused. # crontab -e 0 */4 * * * /usr/local/bin/rsnapshot hourly 30 23 * * * /usr/local/bin/rsnapshot daily

• How do you enable syslogd to accept incoming connections on Snow Leopard from remote loggers?

  - by Emmel

  How do I get syslogd to accept incoming connections from remote hosts on Snow Leopard? I'd like to centralize logging such that various devices and systems send logs to Snow Leopard's syslogd, which normally hangs out on UDP 514. However, I'm unable to get them to successfully be accepted by good ole syslogd. I tcpdumped on the Snow Leopard box to verify that packets are being spouted to port 514 -- they are. I checked that syslogd is listening on 514 -- it's not. Googling around told me that, on older versions of OSX (don't you love the way things change so rapidly on OSX), one just had to add a flag to the syslogd daemon to allow remote; one did this in com.apple.syslogd.plist. However the syslogd daemon has no flags (at least in its man page) that suggests any remote anything. What's the solution to this? Secondary, less import but relevant question: What's 'newsyslog'? I see a plist file but it's not running (apparently). Thanks

• Why would the 'show processlist' command speed up normally slow requests to my remote DB? (connected via VPN)

  - by Hakan B.

  I am running a local Django development server that connects to a remote MySQL server via a VPN (IPSec). Request times are awfully slow and I consistently see timeouts. Attempting to diagnose the problem, I logged in to the remote database and ran: show full processlist Immediately, the local server went from idle to working. The page had not yet completely loaded, but progress had been made (debug logs confirm this). When I ran 'show full processlist' several times more in succession, the request completed quickly. I can currently reproduce this - unless I run 'show full processlist' over and over on the remote server, my local request usually times out. Does anyone have any idea why this would happen? I'm running Django 1.3 and OS X 10.7. Note: I realize this may be entirely not be a question with a clear-cut answer and is probably my fault, but it is odd and reproducable, so I hope someone can at least point me the right direction. Thanks in advance.

• Guests can't access KVM host server by name although nslookup and dig returns correct record

  - by user190196

  So I have a KVM host that also runs an apache server with some yum repos. The VM guests are connected to the default virtual network, which is configured to offer DHCP and forwarding with NAT on virbr0 (192.168.12.1). The guests can successfully access the yum repos on the host by IP address, so for example curl 192.168.122.1/repo1 returns the content without problems. But I'd like to have the guests be able to reach the web server on the host by name rather IP address. I added the desired name record to the host's /etc/hosts file and libvirt's dnsmasq service seems to be serving that correctly to the guests since nslookup and dig successfully resolve the name on the guests: [root@localhost ~]# nslookup repo Server: 192.168.122.1 Address: 192.168.122.1#53 Name: repo Address: 192.168.122.1 [root@localhost ~]# dig repo ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.17.rc1.el6 <<>> repo ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 55938 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;repo.

• How to archive data from a table to a local or remote database in SQL 2005 and SQL 2008

  - by simonsabin

  Often you have the need to archive data from a table. This leads to a number of challenges 1. How can you do it without impacting users 2. How can I make it transactionally consistent, i.e. the data I put in the archive is the data I remove from the main table 3. How can I get it to perform well Points 1 is very much tied to point 3. If it doesn't perform well then the delete of data is going to cause lots of locks and thus potentially blocking. For points 1 and 3 refer to my previous posts DELETE-TOP-x-rows-avoiding-a-table-scan and UPDATE-and-DELETE-TOP-and-ORDER-BY---Part2. In essence you need to be removing small chunks of data from your table and you want to do that avoiding a table scan. So that deals with the delete approach but archiving is about inserting that data somewhere else. Well in SQL 2008 they introduced a new feature INSERT over DML (Data Manipulation Language, i.e. SQL statements that change data), or composable DML. The ability to nest DML statements within themselves, so you can past the results of an insert to an update to a merge. I've mentioned this before here SQL-Server-2008---MERGE-and-optimistic-concurrency. This feature is currently limited to being able to consume the results of a DML statement in an INSERT statement. There are many restrictions which you can find here http://msdn.microsoft.com/en-us/library/ms177564.aspx look for the section "Inserting Data Returned From an OUTPUT Clause Into a Table" Even with the restrictions what we can do is consume the OUTPUT from a DELETE and INSERT the results into a table in another database. Note that in BOL it refers to not being able to use a remote table, remote means a table on another SQL instance. To show this working use this SQL to setup two databases foo and fooArchive create database foo go --create the source table fred in database foo select * into foo..fred from sys.objects go create database fooArchive go if object_id('fredarchive',DB_ID('fooArchive')) is null begin     select getdate() ArchiveDate,* into fooArchive..FredArchive from sys.objects where 1=2       end go And then we can use this simple statement to archive the data insert into fooArchive..FredArchive select getdate(),d.* from (delete top (1)         from foo..Fred         output deleted.*) d         go In this statement the delete can be any delete statement you wish so if you are deleting by ids or a range of values then you can do that. Refer to the DELETE-TOP-x-rows-avoiding-a-table-scan post to ensure that your delete is going to perform. The last thing you want to do is to perform 100 deletes each with 5000 records for each of those deletes to do a table scan. For a solution that works for SQL2005 or if you want to archive to a different server then you can use linked servers or SSIS. This example shows how to do it with linked servers. [ONARC-LAP03] is the source server. begin transaction insert into fooArchive..FredArchive select getdate(),d.* from openquery ([ONARC-LAP03],'delete top (1)                     from foo..Fred                     output deleted.*') d commit transaction and to prove the transactions work try, you should get the same number of records before and after. select (select count(1) from foo..Fred) fred        ,(select COUNT(1) from fooArchive..FredArchive ) fredarchive   begin transaction insert into fooArchive..FredArchive select getdate(),d.* from openquery ([ONARC-LAP03],'delete top (1)                     from foo..Fred                     output deleted.*') d rollback transaction   select (select count(1) from foo..Fred) fred        ,(select COUNT(1) from fooArchive..FredArchive ) fredarchive The transactions are very important with this solution. Look what happens when you don't have transactions and an error occurs   select (select count(1) from foo..Fred) fred        ,(select COUNT(1) from fooArchive..FredArchive ) fredarchive   insert into fooArchive..FredArchive select getdate(),d.* from openquery ([ONARC-LAP03],'delete top (1)                     from foo..Fred                     output deleted.*                     raiserror (''Oh doo doo'',15,15)') d                     select (select count(1) from foo..Fred) fred        ,(select COUNT(1) from fooArchive..FredArchive ) fredarchive Before running this think what the result would be. I got it wrong. What seems to happen is that the remote query is executed as a transaction, the error causes that to rollback. However the results have already been sent to the client and so get inserted into the

• SQL Server Express and VS2010 Web Application .MDF file errors

  - by nannette

  I installed SQL Server 2008 as well as SQL Server Express 2008 on my new Windows 7 development environment, along with Visual Studio 2010. I could get SQL Server 2008 to work fine, but I could not use Express .MDF databases within sample web application projects without receiving the below error: Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed. For instance, I was creating an ASP.NET Web Application. When...(read more)
