• Hiding a file or data from being accessed unless on scheduled days [closed]

  - by gkt.pro

  Possible Duplicate: restricting access to volumes disk even for admin account windows How to restrict use of a computer? I want to limit my access to some data and what I want is that I should be able to access the data only on certain days of the month (e.g., every 3rd day). Is there any way like encryption or some utility to allow me to only access data on specific days? One idea that I was thinking of was to encrypt the data and store the password (will be complex and long so that I couldn't remember it right away) on some website which would then email me back the password in future on those specific days.

• Looking for efficient scaling patterns for Silverlight application with distributed text-file data s

  - by Edward Tanguay

  I'm designing a Silverlight software solution for students and teachers to record flashcards, e.g. words and phrases that students find while reading and errors that teachers notice while teaching. Requirements are: each person publishes his own flashcards in a file on a web server, e.g. http://:www.mywebserver.com/flashcards.txt other people subscribe to that person's flashcards by using a Silverlight flashcard reader that I have developed and entering the URLs of flashcard files they want to subscribe to, URLs and imported flashcards being saved in IsolatedStorage the flashcards.txt file has the following simple format: title, then blocks of question/answers: Jim Smith's flashcards from English class 53-222, winter semester 2009 ==fla Das kann nicht sein. That can't be. ==fla Es sei denn, er kommt nicht. Unless he doesn't come. The user then makes public the URL to his flashcard file and other readers begin reading in his flashcards. In order to lower the bar for non-technical users to contribute, it will even be possible for them to save this text in a Google Document, which they publish and distribute the URL. The flashcard readers will then recognize it is a google document and perform the necessary screen scraping to get at the raw text. I have two technical questions about this approach: What is a best way to plan now for scalability issues: e.g. if your reader is subscribed to 10 flashcard files that are each 200K, it will have to download 2MB of text just to find out if any new flashcards are available. Or can I somehow accurately and consistently get at the last update date/time of text files on servers and published google docs? Each reader will have the ability to allow the person to test himself on imported flashcards and add meta information to them, e.g. categorize them, edit them, etc. This information will be stored in IsolatedStorage along with the important flashcards themselves. What is a good pattern to allow these readers to share and synchronize this meta data, e.g. so when you are looking at a flashcard you can see that 5 other people have made corrections to it. The best solution I can think of now is that the Silverlight readers will have to republish their data to a central database, but then there is the problem of uniquely identifying each flashcard, the best approach seems to be URL + position-in-file, or even better URL + original text of both question and answer fields, but both of these have their obvious drawbacks. The main requirement is that the bar for participation is kept as low as possible, i.e. type text in a google document, publish it, distribute the URL, and you're publishing within the flashcard community. So I want to come up with the most efficient technical solutions in order to compensate for the lack of database, lack of unique ids, etc. For those who have designed or developed similar non-traditional, distributed database projects like this, what advice, experience or best-practice tips you can share on the above two points?

• How can I download a phpbb forum with wget including password protected sections?

  - by Rocky84

  I want to make a download of a forum I moderate, before it closes for good. There's some useful info on it I want to save for myself and I don't want to export the data to another webserver, I just want the pages. Mind you, I'm a user at the forum, not the admin. Now, I googled this and found it can be easily done with wget: How can I download an entire (active) phpbb forum? I used: wget -k -m -E -p -np -R viewtopic.php*p=*,memberlist.php*,faq.php*,posting.php*,search.php*,ucp.php*,viewonline.php*,*sid*,*view=print*,*start=0* -o log.txt http://www.example.com/forum/ I experimented with this, but I can only achieve downloading the publicly visible sections, not the sections you have to log in for. I tried to achieve this by using a Firefox plugin to make a cookies.txt (while my session is logged into the forum) and add --load-cookies file cookies.txt to the command, but still I only get the publicly visible sections. Any suggestions to make this work?

• Purging old Exchange email/content on SBS2003

  - by Aitch

  We have a Windows SBS 2003 server that used to manage email, calendaring and such like for a small organisation via Exchange. We successfully migrated everything to Google Apps for Business about 18 months ago. The server only provides local network services now. We have backed up and virtualized this machine and would now like to purge any residual mail to save disk space and speed up backup etc. The disk space is such that I believe the Exchange mail is still on there somewhere. I've stumbled through System Manager and poked about but cannot confirm whether this is the case. Where would this live and how might I go about it? (Disclaimer: I'm not a Windows admin, Linux is my thing...)

• Why does httpd handle requests for wrong hostnames in SSL mode?

  - by Manuel

  I have an SSL-enabled virtual host for my sites at example.com:10443 Listen 10443 <VirtualHost _default_:10443> ServerName example.com:10443 ServerAdmin [email protected] ErrorLog "/var/log/httpd/error_log" TransferLog "/var/log/httpd/access_log" SSLEngine on SSLProtocol all -SSLv2 SSLCipherSuite HIGH:MEDIUM:!aNULL:!MD5 SSLCertificateFile "/etc/ssl/private/example.com.crt" SSLCertificateKeyFile "/etc/ssl/private/example.com.key" SSLCertificateChainFile "/etc/ssl/private/sub.class1.server.ca.pem" SSLCACertificateFile "/etc/ssl/private/StartCom.pem" </VirtualHost> Browsing to https://example.com:10443/ works as expected. However, also browsing to https://subdomain.example.com:10443/ (with DNS set) shows me the same pages (after SSL certificate warning). I would have expected the directive ServerName example.com:10443 to reject all connection attempts to other server names. How can I tell the virtual host not to serve requests for URLs other than the top-level one?

• Improper integral calculation using numerical intergration

  - by Andrei Taptunov

  I'm interested in calculation of Improper Integral for a function. Particularly it's a Gauss Integral. Using a numerical integration does make sense for a definite integrals but how should I deal with improper integrals ? Is there any was to extrapolate the function "around" negative infinity or should I just remove this part and start integration from some particular value because cumulative sum near "negative infinity" is almost non-existent for Gauss integral? Perhaps there are some algorithms that I'm not aware about.

• Tips on self-learning boot-time fundamentals (grub, disks, partitions, LVMs, etc)?

  - by Harry

  Is there any good resource which I can use to self-learn all the low-level system administration details on Grub, Grub2, disks, partitioning, LVM, etc? I'm comfortable with system admin tasks post-boot but I lack knowledge about both the fundamentals and actuals of all that happens during boot on a Linux system such as Fedora. Any recommendations on how to setup a testbed on my desktop for learning the above? I may not be able to get another machine / harddisk, so may have to rely on something like VirtualBox. But don't know if there are other (better) options... so asking for tips from those who have self-learned / mastered this track themselves.

• how to start a smartdevice application minimized in c#

  - by x86shadow

  I made a smart device application in c# and I want to run it at startup (I know how to do that) but the problem is that I can't make my application to run minimized (hidden) on the first time. I've tried this.Hide() and this.Visible = false and also used ShowWindow API with SW_HIDE(6) but non of them worked. It seems it's impossible to use these methods on Form_Load() or in InitializeComponent() to start the application minimized or hidden. anyone can help me with this ?

• Is it possible to have an external server with in a companies firewall?

  - by Jonathan

  Hi guys, I am sure this is server admin 101,but I am unsure of the answer and would love some help. I am a software developer I have built an application for a client and am currently hosting it successfully on SliceHost. We are now coming out of Beta and the client wants to have the application within their Firewall, but they do not want to deal with headache of hosting and maintaining the server. Is there a way I can recommend that we put our server at SliceHost within their Firewall? Is that an easy thing to do? If that is not possible, what should I recommend to my client? Thanks! Jonathan

• ReadyNAS running slow

  - by Simon Callan

  We have a NetGear ReadyNAS NV+ that we are using just for filestorage. While it appears to be running normally as a fileserver, the admin functions run incredibly slow. Sometimes, backups take so long that they don't finish before the next run is due to start, and if I try to look at the backup logs or download the system logs, all I get is the busy "whirling wheel", until I get a "System is busy message". Is this just the system being bolshy, or is it a sign of problems to come, and what can I do to diagnose them?

• Get rid of case sensitive username in custom membership provider

  Hi, I implemented a custom membership provider in ASP.net MVC, and can't figure out how to make the username non case-sensitive at signin. So, for example, "Solomon" could log in, but "solomon" could not. My implementation is very bare bones. I basically just wrote code for ValidateUser(), and Change Password(). Thanks for the help!

• Windows 2003 Server R2SP2 throws even ID 2269 after installing Excel WebPart in MOSS3

  - by Phil

  We recently added an Excel workbook webpart (read only excel file - no editing) on our Sharepoint 2007 server. Once we did that, approximately 3-4 times an hour event ID 2269 is shown in the Application Log and a few minutes after that, an event id 1002 is displayed in the system long and the Sharepoint Offfce Servers Application pool shuts down. We've already check the "Bypass traverse checking and DCOM settings) per the MS KB and I have opened a ticket with MS Support. Problem is that MS Suppoert (sharepoint) thinks it is an IIS problem and the IIS people think it is a Sharepoint issue. Anyone else seen this problem? If we remove the Excel webpart, everything goes back to normal. The App Pools, SP and SP Central Admin sites are all using the same domain service account. Thanks in advance, Phil

• SQL 2008 Reporting Services Report Manager blank on Win 7

  - by Daniel Root

  I have installed SQL Server 2008 Reporting Services on my development laptop running windows 7. When I browse to the report manager, only the header is shown. The content pane is blank, and there is no 'Site Settings' option, New Folder options, etc. I found plenty of similar stories about SQL 2005, and then the fix was to manage permissions in the virtual directory in IIS. However, in 2008, there is no virtual directory - RS manages this outside of IIS. Per other serverfault articles, I've tried the following: adding my account to the reporting services group changing the service to run as local system made sure localhost was trusted site in IE ran IE as admin installed SQL Server 2008 SP1 There are no errors in the event viewer. Perhaps related, if I browse to the webservice, I also get the error: The permissions granted to user 'Computer\User' are insufficient for performing this operation. (rsAccessDenied)

• How to make a folder (D:\xyz) accessible to only me in Windows-XP?

  - by claws

  Hello, I'm using Windows XP on my lab computer. There is a global folder (d:\xyz). This is my folder and I want this folder to be accessible to only me. It should be invisible even if it is visible they shouldn't be able to open this folder. For now my account has administrative privilages. After few days, I don't know if the Admin lets me have these privilages or not. I heard that soon our XP machines will be upgraded to either vista or windows 7. Will the method of making folder in accessible change for other Windows OSes? How to accomplish this?

• Apache disabled virtual host domains resolve an enabled virtual host

  - by littleK

  I have three virtual hosts defined on apache on my Ubuntu server for three different domains. If I disable two of the virtual hosts (a2dissite) and try to resolve those two URL's in the browser, then the one remaining enabled site will resolve. How can I configure apache so that the domains for the disabled virtual hosts do not resolve? This is how all 3 virtual hosts are configured (info is masked): # domain: myfirstdomain.com # public: /home/me/public/myfirstdomain.com/ <VirtualHost *:80> # Admin email, Server Name (domain name), and any aliases ServerAdmin [email protected] ServerName www.myfirstdomain.com ServerAlias myfirstdomain.com # Index file and Document Root (where the public files are located) DirectoryIndex index.html index.php DocumentRoot /home/me/public/myfirstdomain.com/public # Log file locations LogLevel warn ErrorLog /home/me/public/myfirstdomain.com/log/error.log CustomLog /home/me/public/myfirstdomain.com/log/access.log combined </VirtualHost>
