• How do I learn IPSec VPN implementation on FreeBSD from pfSense

  - by Lang Hai

  I've been trying to figure out a complete working solution for IPSec VPN implementation on FreeBSD but with no luck till now. pfSense seems did a fantastic job on supporting IPSec and even for mobile clients, so I downloaded and installed pfSense hoping to figure out how it works, or at least see some configuration examples, but I couldn't find anything interesting maybe because I'm not familiar with pfSense, so I'd like to ask for help. How pfSense implements IPSec, what tools are used? Where does pfSense store all its configuration files? And since pfSense has its own kernel mods and acts as a different OS, there's no way for us to install it on top of an existing FreeBSD box, and plus that it is such a great project combining those fantastic features, so my question can kinda be extended as: How do we learn from pfSense, and implement its features on top of a regular FreeBSD server?

• precompile App_LocalResources in Visual Studio

  - by jazbit

  My web-application project (not "web-site" project) is translated to 15 different languages using the ASP.NET's built-in resource engine (I have tons of *.aspx.resx file in the "App_LocalREsources" folder). All these resources are precompiled by ASP.NET when I first launch the application and it takes a LOT of time. A LOT. 5-10 minutes. I have to wait 5-10 minutes every time I make soe tiny change to my code to see how it works. Is there any way to compile these resource in Visual Studio? Changing the "Build Action" for all these resx-files to "Embedded resource" does not work :( (or I'm doing it wrong?) PS. I know I can write a batch file that will launch aspnet_compiler.exe and manually compile the app with all the resources, but thats a "hack". I need a documented "Visual Studio"-way to achieve this. Cause I have a setup-project for this app in the same solution, that picks up the "project output" of this web-app (and it won't pick-up any manually precompiled files I made)

• Import and Export for CSV are both broken in Mathematica

  - by dreeves

  Consider the following 2 by 2 array: x = {{"a b c", "1,2,3"}, {"i \"comma-heart\" you", "i \",heart\" u, too"}} If we Export that to CSV and then Import it again we don't get the same thing back: Import[Export["tmp.csv", d]] Looking at tmp.csv it's clear that the Export didn't work, since the quotes are not escaped properly. According to the RFC which I presume is summarized correctly on Wikipedia's entry on CSV, the right way to export the above array is as follows: a b c, "1,2,3" "i ""heart"" you", "i "",heart"" u, too" Importing the above does not yield the original array either. So Import is broken as well. I've reported these bugs to [email protected] but I'm wondering if others have workarounds in the meantime. One workaround is to just use TSV instead of CSV. I tested the above with TSV and it seems to work (even with tabs embedded in the entries of the array).

• Outlook 2007 GAL Phone List

  - by s15199d

  I just spent a lot of time populating Phone Numbers and Fax Numbers in our GAL/Active Directory. The goal of which was to replace our static *.xlsx file that we use as a corporate phone directory. I know I can see the GAL by clicking on the To... button, and I can see more specific info for a particular user, by adding them as a recipient and double-clicking their name in the To: field. Is there any way (inside Outlook) to have a laundry-list view of all users and phone/fax/mobile/address similar to the phone list view for contacts? Are there any other tools that might provide this functionality. I've used a GAL web interface before, but that cost $ and as I recall was challenging to manage.

• Monitoring remote laptops

  - by kaerast

  We're looking for something to monitor around 30 remote laptops that are constantly out on the road, never returning to base except for when there are serious hardware faults that need repairing. These laptops won't always be connected to the internet, they'll have mobile broadband and may work offline most of the time. They will be running a mixture of Windows XP, Vista and 7 and there is currently no server setup. We're primarily interested in making sure that Windows Updates and antivirus updates are happening, and I guess we should also be monitoring remaining disk space, what software is installed and ideally hardware health. It might also be nice if we could gain remote access to perform work on them. My main reason for wanting to monitor them is that it's going to be a real pain to get them back to base if anything goes wrong, so I want to be proactive in ensuring they last as long as possible. Can you recommend what I should be monitoring to ensure a long life? What tools would you use to monitor and maintain these computers?

• Cannot Logout of Facebook with Facebook C# SDK

  - by Ryan Smyth

  I think I've read just about everything out there on the topic of logging out of Facebook inside of a Desktop application. Nothing so far works. Specifically, I would like to log the user out so that they can switch identities, e.g. People sharing a computer at home could then use the software with their own Facebook accounts, but with no chance to switch accounts, it's quite messy. (Have not yet tested switching Windows users accounts as that is simply far too much to ask of the end user and should not be necessary.) Now, I should say that I have set the application to use these permissions: string[] permissions = new string[] { "user_photos", "publish_stream", "offline_access" }; So, "offline_access" is included there. I do not know if this does/should affect logging out or not. Again, my purpose for logging out is merely to switch users. (If there's a better approach, please let me know.) The purported solutions seem to be: Use the JavaScript SDK (FB.logout()) Use "m.facebook.com" instead Create your own URL (and possibly use m.facebook.com) Create your own URL and use the session variable (in ASP.NET) The first is kind of silly. Why resort to JavaScript when you're using C#? It's kind of a step backwards and has a lot of additional overhead in a desktop application. (I have not tried this as it's simply disgustingly messy to do this in a desktop application.) If anyone can confirm that this is the only working method, please do so. I'm desperately trying to avoid it. The second doesn't work. Perhaps it worked in the past, but my umpteen attempts to get it to work have all failed. The third doesn't work. I've tried umpteen dozen variations with zero success. The last option there doesn't work for a desktop application because it's not ASP.NET and you don't have a session variable to work with. The Facebook C# SDK logout also no longer works. i.e. public FacebookLoginDialog(string appId, string[] extendedPermissions, bool logout) { IDictionary<string, object> loginParameters = new Dictionary<string, object> { { "response_type", "token" }, { "display", "popup" } }; _navigateUri = FacebookOAuthClient.GetLoginUrl(appId, null, extendedPermissions, logout, loginParameters); InitializeComponent(); } I remember it working in the past, but it no longer works now. (Which truly puzzles me...) It instead now directs the user to the Facebook mobile page, where the user must manually logout. Now, I could do browser automation to automatically click the logout link for the user, however, this is prone to breaking if Facebook updates the mobile UI. It is also messy, and possibly a worse solution than trying to use the JavaScript SDK FB.logout() method (though not by much). I have searched for some kind of documentation, however, I cannot find anything in the Facebook developer documentation that illustrates how to logout an application. Has anyone solved this problem, or seen any documentation that can be ported to work with the Facebook C# SDK? I am certainly open to using a WebClient or HttpClient/Response if anyone can point to some documentation that could work with it. I simply have not been able to find any low-level documentation that shows how this approach could work. Thank you in advance for any advice, pointers, or links.

• Flash AS3 and XML: way to fix line breaks in htmlText that uses <b> tags in the xml?

  - by HeroicNate

  I'm importing text in from an xml file and i'm using htmlText to try to keep some styling with tags. I have both the regular and bold face font embedded, and the bolding works fine. The problem is that it ads spaces around the words in bold like a paragraph indent and then makes a line-break after them. What's going on, is there a way to fix? fromxmlText.htmlText = theXML.contenttext; If I pull the text in from a txt file it will work fine, but taking it out of an xml file causing funky formatting. lil' help?

  Can someone tell me where I can find the executeable "java_swt"? I see multiple sites that say it is embedded in eclipse, and other sites say it is shipped with Mac swt drops. I have the zip file for a mac called "swt-3.5M6-carbon-macosx.zip" and i have the eclipse IDE installed on my test mac machine and windows machine. But i cannot find this executeable which i need to run an swt app smoothly on mac os x. Any help would be appreciated. Thanks.

• Data-related security Implementation

  - by devdude

  Using Shiro we have a great security framework embedded in our enterprise application running on GF. You define users, roles, permissions and we can control at any fine-grain level if a user can access the application, a certain page or even click a specific button. Is there a recipe or pattern, that allows on top of that, to restrict a user from seeing certain data ? Sample: You have a customer table for 3 factories (part of one company). An admin user can see all customer records, but the user at the local factory must not see any customer data of other factories (for whatever reason). Te security feature should be part of the role definition. Thanks for any input and ideas

• Qt not displaying PNG images on Linux

  - by ereOn

  Hi, I have a software written using Qt which is meant to work on both Windows and Linux. I use PNG images as icons for my QActions, embedded in a resource. I have the following tree directory: / resources/ icons.qrc image.png Here is the content of icons.qrc: <RCC> <qresource prefix="/resources" lang="fr"> <file alias="image.png">image.png</file> </qresource> </RCC> I declare my QIcon like that: QIcon(":/resources/image.png") Under Windows, it works well but on Linux (I only tried on Ubuntu 10.4 so far), the images aren't displayed. Is there anything special I have to do for this to work ? Is this a configuration problem ? Thank you.

• HSQLDB Constraint Violation & SQL Query Log for an HSQLDB in-memory setup

  - by shipmaster

  We have a setup where we are using an embedded HSQLDB for backing Hibernate/JPA unit tests in java, and we are using the in-memory database mode since we simply want the database thrown away after the test run. My problem is that one of the tests is failing due to a constraint violation and HSQLDB lists the column as SYS_CT_286, and the query that appears in the log is the prepared statement where I cant see what the actual parameter values are (they are replaced by '?'). My questions are: 1- Is there a way in which I can see the actual SQL being executed? (like the mysql query log for example?). 2- What exactly is SYS_CT_286? it is not one of my columns, is it a generated column? is there something obvious that may be wrong with it? Thanks.

• What are the best options for a root filesystem hosted on SSD under Linux

  - by stsquad

  I'm working on an embedded system which is going to be booting and hosting it's rootfs on an SSD disk. We are currently looking at using Intel X-18M SSDs. The file system structure will have a fairly static /usr section (modulo software upgrades) and an active /var and /var/log for maintaining state and logging. Given the wear-levelling done by the underlying flash does having separate partitions help or hinder? As modern SSDs appear as straight block devices and hide their mapping magic behind their firmware is there any point trying to optimise the choice of file-system that sits on-top of the SSD? Finally does enable SMART monitoring make any sense in this context or are their SSD specific ways of determining the underlying health of the storage hardware?

• Creating database desktop application with data manipulation in Netbeans using Java Persistence

  - by Lulu

  It's my first time to use Persistence in developing a Java program because I usually connect via JDBC. I read that for large amounts of data, it is best to use persistence. I tried playing with the CRUD example of Netbeans. It's not very helpful thought because it only connects to the DB and allows addition and deletion of records. I need something that will allow me to manipulate the data like if the value from column C1 of table T1 is such, it will retrieve data from table t2. In short, I need to apply conditions before knowing what to retrieve exactly. The example in CRUD example already has a specific table to retrieve and only acts like a database manager. How is it possible to retrieve a specific item first then from this, will determine the next steps to be done. I'm also using embedded JavaDB/Derby as my database (also my first time to use because I usually use remote mysql)

I'd like to use defined resources in XSLT file and get them by this: "document('')//my:resources/"... How can i do that?? ex xsl: <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:my="xslt-gruper-v1.2.xsl" exclude-result-prefixes="my"> <my:resources> <one>tryb</one> </my:resources> <xsl:variable name="res" select="document('')/*/my:resources/("/> </xsl:stylesheet> How can i get access to such structure without exceptions in C#? I'll add that during static transform via ex. Opera everything works fine.

• Exchange 2003 ActiveSync fine but GAL lookups not working

  - by Daniel Lucas

  We have Exchange 2003 SP2 and use ActiveSync for our mobile devices (iOS and sever Android versions). Everything works except for GAL lookups and we've confirmed that the devices and client versions we are trying it on are supposed to support it. The symptom is different depending on the client, but there is never an error. In a nutshell, lookups return no results. This was working previously and we aren't sure what has changed. Are there logs in Exchange or IIS that will allow me to see GAL lookup transactions? Could it be a GAL permissions issue? (No issues with GAL in Outlook) Could it have been caused by upgrading our DCs to 2008 and increasing the forest/domain functional levels?

Please verify your email address and password. The information you provided is incorrect. If the error persists contact gmail.com (Your email provider). Please try again. I tried again, with what i know the password to be, with password show on. I've also deleted the account and tried to create it. I've tried going to the "Last account activity: XXXX details" menu and signing out all devices. I'm continually getting the above error, but the account activities don't seem to show any sign of a mobile attempt to access my mail account. Has anyone had this issue before and how did you sign it. Thanks in advance.

• Garbage collection of Strings returned from C# method calls in ascx pages

  - by Icarus

  Hi, For a web application developed on ASP.NET, we are finding that for user control files (ascx) we are returning long strings as a result of method calls. These are embedded in the ascx pages using the special tags <% %> When performing memory dump analysis for the application, we find that many of those strings are not being garbage collected. Also, the ascx pages are compiled to temporary DLLs and they are held in memory. Is this responsible for causing the long strings to remain in memory and not be garbage collected ? Note : The strings are larger than 85K in size.

• Intel video driver upgrade now makes my external monitor display red-only with HDMI cable.

  - by Eli

  I have an HP G60 notebook with a Mobile Intel 4 Series Express Chipset video display (Driver version is 8.15.10.2021). OS is Win7 Home Premium. I also have an LG widescreen display that I was connecting to the laptop using an HDMI cable. It was working great, until I applied an Intel 4 Series Express Chipset update from Windows Update. After the update, if I plug the laptop to the monitor using the HDMI cable, it appears I only get the Magenta channel, cause that is all I see. If I connect with the VGA cable, it works fine. So, is it possible it is just the HDMI cable (which IS cheap in this case - fire sale at Blockbuster), and not related to the video driver update at all?

• Asynchronous Processing in JBoss 6 ("Comet")

  - by chris_l

  edit: Retagged as tomcat, since this is really a question about the Tomcat embedded inside JBoss 6, rather than JBoss itself I have an extremely simple servlet, which works on Glassfish v3. It uses Servlet 3.0 Asynchronous Processing. Here's a simplified version (which doesn't do much): @WebServlet(asyncSupported=true) public class SimpleServlet extends HttpServlet { @Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { final AsyncContext ac = request.startAsync(); ac.setTimeout(3000); } } On JBoss 6.0.0 (Milestone 2), I get the following Exception: java.lang.IllegalStateException: The servlet or filters that are being used by this request do not support async operation at org.apache.catalina.connector.Request.startAsync(Request.java:3096) at org.apache.catalina.connector.Request.startAsync(Request.java:3090) at org.apache.catalina.connector.RequestFacade.startAsync(RequestFacade.java:990) at playcomet.SimpleServlet.doGet(SimpleServlet.java:18) at javax.servlet.http.HttpServlet.service(HttpServlet.java:734) ... Do I have to do anything special to enable Asynchronous Processing in JBoss 6? Or do I need an additional deployment descriptor? ...

• how to run apache2 or nginx + php on iPhone? [closed]

  - by Rubytastic

  Is there a way to run Apache2 or Nginx with PHP on the iPhone? Im surprised so little info is available on this topic, as it seems quite interesting to host websites on an iPhone. Consider slow 3G connections or no 3G at all, and you want to demonstrate some webapplication you wrote... hosting them on the iphone would be an awsome way to fix the speed issues with the mobile network speeds. For the Ipad there are several addoptions available, nothing much usable on iphone / nginx apache2 search terms anywhere :( I want to host some websites on my iphone for demonstration purposes. So when im "out the office" Ill be able to very fast browse some websites that I host on the Iphone. there is no decent information out there, does anyone have a lead on how to do this? My question is specific to if nginx or apache2 can be run on the iphone, it would be nice if PHP would run on it too

• Best calculator software to help programmers

  - by RHaguiuda

  As a embedded systems programmer I always need to make lots of base conversions (dec to hex, hex to bin and so on...), and I must admit: Windows 7 calculator is a good calc, but too limited in my point of view. I work a lot with communications protocols and it`s common to need some base conversion in this field of knowledge. I`m looking for a calculator software (not a hardware one), to help with base conversions, but it must also support scientific calc. Can anyone help on this? Since this subject is intended to help programmers, I did not ask this in SuperUser.com. Thanks.

• My wifi internet router connection resets when more devices connected

  - by joeeoj

  The wifi internet router is connected directly to Internet cable. The main Pc is attached to it via LAN cable, while 1 laptop and 3 mobile phones connect to it via wifi. Whenever 2 or more devices connect via wifi, the internet connection breaks after one minute and internet connection resets. I tracked this behaviour for weeks, and came to conclusion: It seems like some 'device 1' got IP then it went to suspend mode. Then 'device 2' connected to router and got the same IP. Then the 'device 1' woke up from suspend mode and tried to use his old IP. The router sees that 2 same IP addresses exists and automatically reset internet connection. Is this possible? Have I tracked the problem correctly and how to solve it? The router is set to lease 100 IP addresses to devices who try to connect. The password is strong and no hacker's device is being connected to my wifi network. Tried changing password and AP's name.
