• Restrict access to a specific URL, running on IIS7 / ASP.NET

  - by frankadelic

  I am deploying a public ASP.NET website on an IIS7 web farm. The application runs on 3 web servers and is behind a firewall. We want to create a single page on the website that is accessible only to internal users. It is primarily used for diagnostics, trigger cache expiry, etc. /admin/somepage.aspx What is the best way to control access to this page? We need to: Prevent all external (public) users from accessing the URL. Permit specific internal users to access the page, only from certain IPs or networks. Should this access control be done at the (a) network level, (b) application level, etc.?

• Can Goldberg algorithm in ocamlgraph be used to find Minimum Cost Flow graph?

  - by Tautrimas

  I'm looking for an implementation to the Minimum Cost Flow graph problem in OCaml. OCaml library ocamlgraph has Goldberg algorithm implementation. The paper called Efficient implementation of the Goldberg-Tarjan minimum-cost flow algorithm is noting that Goldberg-Tarjan algorithm can find minimum cost graph. Question is, does ocamlgraph algorithm also find the minimum cost? Library documentation only states, that it's suitable at least for the maximum flow problem. If not, does anybody have a good link to a nice any minimum cost optimization algorithm code? I will manually translate it into OCaml then. Forgive me, if I missed it on Wikipedia: there are too many algos on flow networks for the first day!

• SonicWall HA "gotchas"?

  - by Mark Henderson

  We're looking to move away from PFSense and CARP to a pair of SonicWall NSA 24001 configured in Active/Passive for High Availability. I've never dealt with SonicWall before, so is there anything I should know that their sales guy won't tell me? I'm aware that they had an issue with a lot of their devices shutting down connectivity because of a licensing fault, and they have an overtly complex management GUI (on the older devices at least), but are there any other big "gotchas" that I need to be aware of before committing a not insubstantial amount of money towards these devices? 1If you're outside the US, the SonicWall global sites suck balls. Use the US site for all your product research, and then use your local site when you're after local information.

• Website filtering for OpenVPN clients

  - by Asche

  I am currently trying to block some websites by their domain names for all the clients of my OpenVPN server. My first idea was to use the /etc/hosts file. But, its effects seem to be limited to the host only and not to be taken in consideration by OpenVPN. I then tried to configure bind9 and to interface it with OpenVPN, but that solution was unsuccessful and uneasy to use. After this, I considered using iptables to drop all the packets from/to those websites but that forum thread made me thought otherwise since iptables' behavior with FQDN may generate complex issues. Have you got a solution to block websites for all clients using an OpenVPN server on which I am root?

• How SSD hard drive affected speed of your website (asp.net/linq/ms sql database)

  - by Sergey Osypchuk

  I have a small database (<1G) But we have a lot of complex logi? in website and client complains on render time, which is 3-5 seconds. We are not google, and thousands of users a day is our dream, so size is not a problem, but speed is important. Can anybody share with experience with SSD drives for ASP.NET (MVC)/LINQ/MS SQL based application ? How you performance increased? UPDATE: this whitepaper states that it will be 20 times faster. http://www.texmemsys.com/files/f000174.pdf

• Detecting network adapter changes on the iPhone

  - by theactiveactor

  Say that there are no WIFI networks currently available and my network-enabled app is connected over 3G. How can I detect if a user has roamed into a WIFI network? I would also like to detect the case when the user is connected over WIFI and suddenly received 3G signal. In other words, I would like to be asynchronously notified of network adapter changes. I tried using the SCNetworkReachability framework asynchronously but found that for some reason, I am not receiving Wifi-related events (i.e. adapter on/off) when connected over 3G.

• users unable to add registry keys to HKCU

  - by Eds

  I may not have this 100% correct so need some clarification. Are normal users on a 2003 terminal server allowed to add registry keys the their own HKCU section in the registry, or are they only allowed to edit existing ones? The reason I ask is that we have 3 keys that we need to add for each user on login. I thought it would be as simple as having a straightforward batchscript run that silently adds the keys for the user. Here is what I used: regedit.exe "C:\Documents and Settings\All Users\Desktop\example.reg" When the user runs this batch scipt, they see nothing as you would expect, but the keys are not added. If I simply run the .reg file as the user, it asks if I want to add the key, but then has an error saying there was an error accessing the registry. Do I need something a bit more complex to accomplish this task. Many Thanks Eds EDIT: Contents of .reg file Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Policies\Microsoft\office\14.0\outlook\Security] "PromptSimpleMAPINameResolve"=dword:00000002 "PromptSimpleMAPIOpenMessage"=dword:00000002 "PromptSimpleMAPISend"=dword:00000002

• Android - modes of connectivity, device identification and device inter-communication?

  - by MalcomTucker

  Can someone explain a couple of very simple concepts to me - I'm interested in mobile devices running android and how they are identified over networks. Some scenarios: Device is connected over WiFi - presumably the device has a standard IP address as with any host and can communicate with any other android host over TCP/IP (assuming it knows the participating device's IP? Device is connected over bluetooth - how are devices identified in this case? Device is connected over mobile operator's network - this is the one I'm interested in and confused by - is there anyway for two or more devices to discover each other and communicate via the mobile operator's network? How does a device communicate with a backend server in this scenario? In other words, how do apps and devices communicate when not connected to a WiFi network? Thanks for any advice..

• Adobe Reader - Content Preparation progress

  - by kubal5003

  Hello, I was wondering recently if is it just me or anyone else noticed it: why Adobe Reader after opening every single document displays "Content preparation" window with progress bar and it lasts for ages.. ? On linux pdf readers work hell lot better (faster), on windows other readers also work faster. Some years back in the past Adobe Reader also used to be quick. What has happened? PDF files aren't bigger/more complex compared to 3-4 years ago. Computers are at least dual core and with much more ram and displaying pdf files is getting slower and slower..

• Exchange 2003 automated mailbox size report

  - by Morris

  I have a question if I may. I have been looking for a while for something that can report user mailbox sizes and percentage used against their quota or something that can warn me when a mailbox is getting close to the quota. I know the user receives a warning but how can I send that same warning a centralized mailbox so we can be pro-active in our support. Either a script or an application that can do this will be helpful. Unfortunately my scripting skills are useless for something this complex. Any ideas of what can be used will be appreciated.

• Network Security and Encryption explained in laymen terms

  - by Ehrann Mehdan

  Although I might pretend very well that I known a thing about networks or security and it might help me pass an interview, or fix a bug, I don't really feel I'm fooling anyone. I'm looking for a laymen terms explanation of nowadays network security concepts and solutions. The information is scattered around and I didn't find a resource for "dummies" like me (e.g experienced Java developers that can speak the jargon but have no real clue what it means) Topics I have a weak notion about and want to understand better as a Java developer PGP Public / Private keys RSA / DES SSL and 2 way SSL (keystore / trustore) Protecting against Man in the middle fraud Digital Signature and Certificates Is there a resource out there that really explains it in a way that doesn't require a Cisco certificate / Linux lingo / know what is subnet masking or other plumbing skills?

• Beginner's resources/introductions to classification algorithms.

  - by Dirk

  Hi, everybody. I am entirely new to the topic of classification algorithms, and need a few good pointers about where to start some "serious reading". I am right now in the process of finding out, whether machine learning and automated classification algorithms could be a worthwhile thing to add to some application of mine. I already scanned through "How to Solve It: Modern heuristics" by Z. Michalewicz and D. Fogel (in particular, the chapters about linear classifiers using neuronal networks), and on the practical side, I am currently looking through the WEKA toolkit source code. My next (planned) step would be to dive into the realm of Bayesian classification algorithms. Unfortunately, I am lacking a serious theoretical foundation in this area (let alone, having used it in any way as of yet), so any hints at where to look next would be appreciated; in particular, a good introduction of available classification algorithms would be helpful. Being more a craftsman and less a theoretician, the more practical, the better... Hints, anyone?

• Software Engineer's explanation of Facebook photo privacy, with UML diagram?

  - by Alex R

  Facebook photo privacy is more complex than most people think - including the bloggers who fill the Internet trying to explain it in simple terms. Not only there is the basic album-level privacy setting to consider, but also what happens with Tagging (and related privacy settings) as well as the Share button when clicked by a Friend. Has anybody seen a good, engineering-type (e.g. UML) diagram? I envision it should include the various privacy "states" a photo can be in, what causes state transitions, and the characteristics of each state? Thanks

• Why some recovery tools are still able to find deleted files after I purge Recycle Bin, defrag the disk and zero-fill free space?

  - by Ivan

  As far as I understand, when I delete (without using Recycle Bin) a file, its record is removed from the file system table of contents (FAT/MFT/etc...) but the values of the disk sectors which were occupied by the file remain intact until these sectors are reused to write something else. When I use some sort of erased files recovery tool, it reads those sectors directly and tries to build up the original file. In this case, what I can't understand is why recovery tools are still able to find deleted files (with reduced chance of rebuilding them though) after I defragment the drive and overwrite all the free space with zeros. Can you explain this? I thought zero-overwritten deleted files can be only found by means of some special forensic lab magnetic scan hardware and those complex wiping algorithms (overwriting free space multiple times with random and non-random patterns) only make sense to prevent such a physical scan to succeed, but practically it seems that plain zero-fill is not enough to wipe all the tracks of deleted files. How can this be?

• How can I send super large files directly to another computer in the Internet for free?

  - by Cruise

  I regulary need to transfer very large files (30 GB) to my friend - financial statistics. I don't have any problem with bandwidth: it is very broad here. I did some research in the area, so: 1. I would not use FTP, as it is very tricky to get it working behind a NAT. 2. I would not use Skype/MSN/ICQ, as it is not designed for file transfer and it underperforms on the huge files. 3. I would not use file-sharing services, as I need to pay for big files (30 GB is a problem here) and I don't like holding any piece of my data on the third-party server. So, I need some smart tool that will do what I need: sending files directly browser-to-browser and not browser-server-browser. Is it so complex? Is there some web application in the Internet that can do this?

• What is the best drive cleaner?

  - by allindal

  What is the best drive "cleaner" application, an application that deletes roaming, temp. and different useless caches. Something similar to CCleaner, but more powerful. I need it to delete more than the basic stuff. Like duplications of complex files or redundancies, (example... for every game there's the DirectX suite) without deleting program essential files, obviously. I know most of this has to do with my selection of these programs, but I haven't seen anything that lets me select types of files to delete, not just specific files.

• Coffeeshop limits Internet connection to 30 minutes -- how does it recognize me if I delete my cooki

  - by Andrew

  I was connected to the Internet in a coffeeshop earlier today, but I was only allowed 30 minutes of access. I tried deleting my cookies after my time was up (though admittedly I didn't delete my Flash cookies -- would that have solved the problem?), but the connection still recognized that I'd already used 30 minutes, so I couldn't connect again. How did the connection recognize me still? The wireless was unprotected (no code or password), it just had a portal you had to pass through upon the initial connection. I'm not terribly familiar with web development or computer networks, so just trying to get a better idea of what's happening (and possibly to know what to do next time I use up my minutes =)).

• How to programmatically control slave computer on BIOS level?

  - by PovilasSid

  I want to run some test on hardware level. My goal is to create or find a way to control one computer from another down to BIOS settings changing. For example: Master computer sends a signal for slave to restart and opens BIOS settings dialog. Master computer sends a signal to slave to change BIOS parameters and then restart. Then slave fully boots up master starts up some software on slave. Then software finishes operations cycle continues till certain conditions are met. I know that I am looking for a complex thing but mainly what I need are correct keywords because now I am being flooded by BIOS configurations tutorials. Main concerns: Is it possible without using any custom tailer chip? How can master monitor salve`s hardware activity? How to let master handled more than one slave? How what connections are needed to create this kind of setup? (cables)

• Sending large files - do any vendors sell their solution?

  - by Rob Nicholson

  We currently have an account with www.mailbigfile.com to allow us to send & receive files which exceed our client's email limits. In our industry, a 10MB limit is not unknown. Mailbigfile works fine for what it is but increasingly, our clients are starting to block it as a security risk. A solution would be for us to license the software and run it from our own web server which is far less likely to be blocked. Does anyone know of vendors in this market? We are looking at web collaboration systems but that's a much bigger project. The technology behind www.mailbigfile.com isn't that complex (http upload, email notification and then http download) so I'm hoping it won't be very expensive. Cheers, Rob.

• Looking for WYSIWYG tool to create and edit HTML5 based presentations (slides)

  - by peterp

  There are a lot of different implementations for HTML5 based slide presentations out there, like Google Slides or S5. But all that I have seen so far, seem to need a person being able to (and willing to) read and write HTML-Code. My company still uses Powerpoint, but some people are quite unhappy about its limitedness, e.g. the lack of possibilites to embed animation (other than just appear/disappear) without using flash. I'd love to suggest a state-of-the-art solution based on HTML5, but I don't even need to think about suggesting a solution where the project people need a techie to add or edit the content of a slide. I am not looking for an editor for non-technies to create complex HTML5/javascript based animations, of course, those should be done by a developer... basically non-technies should be capable of doing the stuff they are doing in powerpoint now. Thanks in advance for your suggestions, Peter

• Restreaming video from XSplit to multiple JustinTV/TwitchTV channels in different resolutions and bitrates

  - by lmojzis

  I have a really simple question but the answer may be a little more complex I guess. Okay. Let's go. I have an Application called Xsplit Broadcaster (http://www.xsplit.com/). It supports streaming video through RTMP. Now what I want to do is this: +--(720p)--> TwitchTV FirstChannel XSplit --(720p RTMP)-->[MyTranscodingServer]--+ +--(360p)--> TwitchTV SecondChannel Is there a simple way to do this? Additional info: Both channels accept standard RTMP stream on their RTMP endpoint using either username/password or streamkey. The server operating system is GNU/Linux

• What is the best IP/Subnet set up strategy for a multi-server webhosting setup?

  - by Roy Andre

  Sorry for the mixed-up title, but let me try to explain better: We run a hosting solution, which until now has supported shared hosting and VPSes. Easy enough. We are now getting larger clients which require a more complex setup. We have more or less settled the server-setup itself, which will consist of: 1-2 Frontend Proxy/Load balancing servers 2+ Application servers 1 Database server 1 optional Memcached server The issue we are dealing with is to agree on a flexible and easy-to-maintain IP setup. So far we've been into VLAN'ing the internal servers in its own subnet, we've though of assigning an official IP to each server, and so on. What will be the best approach here? Any best practices? Using one official IP on the Frontend server, and then just set up an internal subnet for the servers behind that? We could then just NAT in any eventual sources required to access for instance the DB server directly over 3306.

• Too big a difference between Loud and Quiet when watching DVD's... constantly have to adjust volume.

  - by Dan

  It is hard for me to find the right volume for my computer to watch my dvd's on because it seems like most reasonable volumes become overwhelming at the loudest parts of a movie and it is hard to even make out the dialog at the quietest parts. I find I'm constantly adjusting the volume during the course of a movie. Are there ways to make the difference between the louds and the quiets not so extreme? (both computer related solutions and non-computer related solutions welcome). Like moving my speakers across the room and increasing the volume? or the opposite? Or would would the extremes be less noticeable if I used headphones? Are there movie players that might have more complex sound adjustment features? If there is a software solution out there for linux that would be great too. Thanks, Dan
