• Optimal storage of data structure for fast lookup and persistence

  - by Mikael Svenson

  Scenario I have the following methods: public void AddItemSecurity(int itemId, int[] userIds) public int[] GetValidItemIds(int userId) Initially I'm thinking storage on the form: itemId -> userId, userId, userId and userId -> itemId, itemId, itemId AddItemSecurity is based on how I get data from a third party API, GetValidItemIds is how I want to use it at runtime. There are potentially 2000 users and 10 million items. Item id's are on the form: 2007123456, 2010001234 (10 digits where first four represent the year). AddItemSecurity does not have to perform super fast, but GetValidIds needs to be subsecond. Also, if there is an update on an existing itemId I need to remove that itemId for users no longer in the list. I'm trying to think about how I should store this in an optimal fashion. Preferably on disk (with caching), but I want the code maintainable and clean. If the item id's had started at 0, I thought about creating a byte array the length of MaxItemId / 8 for each user, and set a true/false bit if the item was present or not. That would limit the array length to little over 1mb per user and give fast lookups as well as an easy way to update the list per user. By persisting this as Memory Mapped Files with the .Net 4 framework I think I would get decent caching as well (if the machine has enough RAM) without implementing caching logic myself. Parsing the id, stripping out the year, and store an array per year could be a solution. The ItemId - UserId[] list can be serialized directly to disk and read/write with a normal FileStream in order to persist the list and diff it when there are changes. Each time a new user is added all the lists have to updated as well, but this can be done nightly. Question Should I continue to try out this approach, or are there other paths which should be explored as well? I'm thinking SQL server will not perform fast enough, and it would give an overhead (at least if it's hosted on a different server), but my assumptions might be wrong. Any thought or insights on the matter is appreciated. And I want to try to solve it without adding too much hardware :) [Update 2010-03-31] I have now tested with SQL server 2008 under the following conditions. Table with two columns (userid,itemid) both are Int Clustered index on the two columns Added ~800.000 items for 180 users - Total of 144 million rows Allocated 4gb ram for SQL server Dual Core 2.66ghz laptop SSD disk Use a SqlDataReader to read all itemid's into a List Loop over all users If I run one thread it averages on 0.2 seconds. When I add a second thread it goes up to 0.4 seconds, which is still ok. From there on the results are decreasing. Adding a third thread brings alot of the queries up to 2 seonds. A forth thread, up to 4 seconds, a fifth spikes some of the queries up to 50 seconds. The CPU is roofing while this is going on, even on one thread. My test app takes some due to the speedy loop, and sql the rest. Which leads me to the conclusion that it won't scale very well. At least not on my tested hardware. Are there ways to optimize the database, say storing an array of int's per user instead of one record per item. But this makes it harder to remove items.

• Using Oracle ADF Data Visualization Tools (DVT) Line Graphs to Display Weather Information

  - by Christian David Straub

  OverviewA guest post by Jeanne Waldman.I have a simple JDeveloper Fusion application that retrieves weather data. I wanted to compare the week's temperatures of different locations in a graph. I decided to check out the dvt:lineGraph component, and it took me a few minutes to add it to my jspx page and supply it with data.Drag and Drop the dvt:lineGraph onto your pageI opened my .jspx page in design modeIn the Component Palette, I selected ADF Data Visualization.Then I dragged 'Line' onto my page.A dialog popped up giving me options of the type of line graph. I chose the default.A lineGraph displayed with some default data. Hook up your weather dataNow I wanted to hook up my own data. I browsed the tagdoc, and I found the tabularData attribute.Attribute: tabularDataType: java.util.ListTagDoc:Specifies a list of data that the graph uses to create a grid and populate itself. The List consists of a three-member Object array for each data value to be passed to the graph. The members of each array must be organized as follows: The first member (index 0) is the column label, in the grid, of the data value. This is generally a String. If the graph has a time axis, then this should be a Java Date. Column labels typically identify groups in the graph. The second member (index 1) is the row label, in the grid, of the data value. This is generally a String. Row labels appear as series labels in the graph (usually in the legend). The third member (index 2) is the data value, which is usually a Double.The first member is the column label of the data value. This would be the day of the week.The second member is the row label of the data value. This would be the location name.The third member is the data value, usually a Double. This would be the temperature. I already had all this information, I just needed to put it in a List with a three-member Object array for each data value.   /**    * This is used for the lineGraph to show the data for each location.    */   public List<Object[]> getTabularData()   {      List<Object[]> tabularData = new ArrayList<Object []>();      List<WeatherForecast> weatherForecastList = getWeatherForecastList();      // loop through the list and build up the tabular data. Then cache it.      for(WeatherForecast wf : weatherForecastList)      {        List<ForecastDay> forecastDayList = wf.getForecastDayList();        String location = wf.getLocation();        for (ForecastDay fday : forecastDayList)        {          String day = fday.getPrettyDate();          String highTemp = fday.getHighF();          tabularData.add(new Object[]{day, location, Double.valueOf(highTemp)});        }             }      return tabularData;    }  Now I bound the lineGraph to this method by setting tabularData to#{weatherForAllLocationsBean.tabularData}weatherForAllLocationsBean is my bean that is defined in faces-config.xml. Adding a barGraphIn about 30 seconds, I added a barGraph with the same data. I dragged and dropped a bar graph onto the page, used the same tabularData as I did in the line graph. The page looks like this:  ConclusionI was very happy how fast it was to hook up my weather data to these graphs. They look great, and they have built in functionality. For instance, I can hide/show a location by clicking on the name of the location in the legend.

• [GEEK SCHOOL] Network Security 2: Preventing Disaster with User Account Control

  - by Ciprian Rusen

  In this second lesson in our How-To Geek School about securing the Windows devices in your network, we will talk about User Account Control (UAC). Users encounter this feature each time they need to install desktop applications in Windows, when some applications need administrator permissions in order to work and when they have to change different system settings and files. UAC was introduced in Windows Vista as part of Microsoft’s “Trustworthy Computing” initiative. Basically, UAC is meant to act as a wedge between you and installing applications or making system changes. When you attempt to do either of these actions, UAC will pop up and interrupt you. You may either have to confirm you know what you’re doing, or even enter an administrator password if you don’t have those rights. Some users find UAC annoying and choose to disable it but this very important security feature of Windows (and we strongly caution against doing that). That’s why in this lesson, we will carefully explain what UAC is and everything it does. As you will see, this feature has an important role in keeping Windows safe from all kinds of security problems. In this lesson you will learn which activities may trigger a UAC prompt asking for permissions and how UAC can be set so that it strikes the best balance between usability and security. You will also learn what kind of information you can find in each UAC prompt. Last but not least, you will learn why you should never turn off this feature of Windows. By the time we’re done today, we think you will have a newly found appreciation for UAC, and will be able to find a happy medium between turning it off completely and letting it annoy you to distraction. What is UAC and How Does it Work? UAC or User Account Control is a security feature that helps prevent unauthorized system changes to your Windows computer or device. These changes can be made by users, applications, and sadly, malware (which is the biggest reason why UAC exists in the first place). When an important system change is initiated, Windows displays a UAC prompt asking for your permission to make the change. If you don’t give your approval, the change is not made. In Windows, you will encounter UAC prompts mostly when working with desktop applications that require administrative permissions. For example, in order to install an application, the installer (generally a setup.exe file) asks Windows for administrative permissions. UAC initiates an elevation prompt like the one shown earlier asking you whether it is okay to elevate permissions or not. If you say “Yes”, the installer starts as administrator and it is able to make the necessary system changes in order to install the application correctly. When the installer is closed, its administrator privileges are gone. If you run it again, the UAC prompt is shown again because your previous approval is not remembered. If you say “No”, the installer is not allowed to run and no system changes are made. If a system change is initiated from a user account that is not an administrator, e.g. the Guest account, the UAC prompt will also ask for the administrator password in order to give the necessary permissions. Without this password, the change won’t be made. Which Activities Trigger a UAC Prompt? There are many types of activities that may trigger a UAC prompt: Running a desktop application as an administrator Making changes to settings and files in the Windows and Program Files folders Installing or removing drivers and desktop applications Installing ActiveX controls Changing settings to Windows features like the Windows Firewall, UAC, Windows Update, Windows Defender, and others Adding, modifying, or removing user accounts Configuring Parental Controls in Windows 7 or Family Safety in Windows 8.x Running the Task Scheduler Restoring backed-up system files Viewing or changing the folders and files of another user account Changing the system date and time You will encounter UAC prompts during some or all of these activities, depending on how UAC is set on your Windows device. If this security feature is turned off, any user account or desktop application can make any of these changes without a prompt asking for permissions. In this scenario, the different forms of malware existing on the Internet will also have a higher chance of infecting and taking control of your system. In Windows 8.x operating systems you will never see a UAC prompt when working with apps from the Windows Store. That’s because these apps, by design, are not allowed to modify any system settings or files. You will encounter UAC prompts only when working with desktop programs. What You Can Learn from a UAC Prompt? When you see a UAC prompt on the screen, take time to read the information displayed so that you get a better understanding of what is going on. Each prompt first tells you the name of the program that wants to make system changes to your device, then you can see the verified publisher of that program. Dodgy software tends not to display this information and instead of a real company name, you will see an entry that says “Unknown”. If you have downloaded that program from a less than trustworthy source, then it might be better to select “No” in the UAC prompt. The prompt also shares the origin of the file that’s trying to make these changes. In most cases the file origin is “Hard drive on this computer”. You can learn more by pressing “Show details”. You will see an additional entry named “Program location” where you can see the physical location on your hard drive, for the file that’s trying to perform system changes. Make your choice based on the trust you have in the program you are trying to run and its publisher. If a less-known file from a suspicious location is requesting a UAC prompt, then you should seriously consider pressing “No”. What’s Different About Each UAC Level? Windows 7 and Windows 8.x have four UAC levels: Always notify – when this level is used, you are notified before desktop applications make changes that require administrator permissions or before you or another user account changes Windows settings like the ones mentioned earlier. When the UAC prompt is shown, the desktop is dimmed and you must choose “Yes” or “No” before you can do anything else. This is the most secure and also the most annoying way to set UAC because it triggers the most UAC prompts. Notify me only when programs/apps try to make changes to my computer (default) – Windows uses this as the default for UAC. When this level is used, you are notified before desktop applications make changes that require administrator permissions. If you are making system changes, UAC doesn’t show any prompts and it automatically gives you the necessary permissions for making the changes you desire. When a UAC prompt is shown, the desktop is dimmed and you must choose “Yes” or “No” before you can do anything else. This level is slightly less secure than the previous one because malicious programs can be created for simulating the keystrokes or mouse moves of a user and change system settings for you. If you have a good security solution in place, this scenario should never occur. Notify me only when programs/apps try to make changes to my computer (do not dim my desktop) – this level is different from the previous in in the fact that, when the UAC prompt is shown, the desktop is not dimmed. This decreases the security of your system because different kinds of desktop applications (including malware) might be able to interfere with the UAC prompt and approve changes that you might not want to be performed. Never notify – this level is the equivalent of turning off UAC. When using it, you have no protection against unauthorized system changes. Any desktop application and any user account can make system changes without your permission. How to Configure UAC If you would like to change the UAC level used by Windows, open the Control Panel, then go to “System and Security” and select “Action Center”. On the column on the left you will see an entry that says “Change User Account Control settings”. The “User Account Control Settings” window is now opened. Change the position of the UAC slider to the level you want applied then press “OK”. Depending on how UAC was initially set, you may receive a UAC prompt requiring you to confirm this change. Why You Should Never Turn Off UAC If you want to keep the security of your system at decent levels, you should never turn off UAC. When you disable it, everything and everyone can make system changes without your consent. This makes it easier for all kinds of malware to infect and take control of your system. It doesn’t matter whether you have a security suite or antivirus installed or third-party antivirus, basic common-sense measures like having UAC turned on make a big difference in keeping your devices safe from harm. We have noticed that some users disable UAC prior to setting up their Windows devices and installing third-party software on them. They keep it disabled while installing all the software they will use and enable it when done installing everything, so that they don’t have to deal with so many UAC prompts. Unfortunately this causes problems with some desktop applications. They may fail to work after you enable UAC. This happens because, when UAC is disabled, the virtualization techniques UAC uses for your applications are inactive. This means that certain user settings and files are installed in a different place and when you turn on UAC, applications stop working because they should be placed elsewhere. Therefore, whatever you do, do not turn off UAC completely! Coming up next … In the next lesson you will learn about Windows Defender, what this tool can do in Windows 7 and Windows 8.x, what’s different about it in these operating systems and how it can be used to increase the security of your system.

• As a game developer, which data structure use for develop the game? [duplicate]

  - by Rizwanabbasi

  This question already has an answer here: When should vector/list be used? 5 answers We are developing a game for bank robbery. The game plots a bank robbery. Lots of people witness that robbery. Our game will load the lists of suspected offenders while the players (witnesses) will have to identify the offenders of this robbery. Game should load list of offenders to identify the one as quickly as possible. Admin can add/remove offenders in the lists and two or more lists of offenders can also be merged into one (to show it to the player). As a game developer, which data structure we should use for develop the game? Justify your selection with solid arguments. Remember the most critical requirement is that the list should load super fast.

• Setting user's group and umask has no effect

  - by Andrew Vit

  I'm trying to allow my "deploy" user to have access to files created by www-data: I added "deploy" to the www-data group. I set umask to 002. When I run the following commands, I'm not seeing the result I expect: deploy@ubuntu-lucid-32-generic:/var/www$ groups www-data adm dialout cdrom plugdev lpadmin sambashare admin deploy sysadmin deploy@ubuntu-lucid-32-generic:/var/www$ newgrp www-data deploy@ubuntu-lucid-32-generic:/var/www$ umask 0002 deploy@ubuntu-lucid-32-generic:/var/www$ mkdir test deploy@ubuntu-lucid-32-generic:/var/www$ ls -la test total 0 drwxr-xr-x 1 deploy deploy 68 Nov 7 20:37 . drwxr-xr-x 1 deploy deploy 476 Nov 7 20:37 .. I see that: The folder doesn't belong to the www-data group. The folder permissions don't have group-write (775). Note that the /var/www directory is owned by the deploy user: drwxr-xr-x 1 deploy deploy 510 Nov 7 20:45 . How can I give www-data selective access to directories? Or, how to share the /var/www directory with my deploy user: I don't care who owns it, as long as I can write to it, and so can www-data. (Ideally I would set up a directory with SGID access for www-data.)

• How to move an UIView along a curved CGPath according to user dragging the view

  - by Felipe Cypriano

  I'm trying to build a interface that the user can move his finger around the screen an a list of images moves along a path. The idea is that the images center nevers leaves de path. Most of the things I found was about how to animate using CGPath and not about actually using the path as the track to a user movement. I need to objects to be tracked on the path even if the user isn't moving his fingers over the path. For example (image bellow), if the object is at the beginning of the path and the user touches anywhere on the screen and moves his fingers from left to right I need that the object moves from left to right but following the path, that is, going up as it goes to the right towards the path's end. This is the path I've draw, imagine that I'll have a view (any image) that the user can touch and drag it along the path, there's no need to move the finger exactly over the path. If the user move from left to right the image should move from left to right but going up if need following the path. This is how I'm creating the path: CGPoint endPointUp = CGPointMake(315, 124); CGPoint endPointDown = CGPointMake(0, 403); CGPoint controlPoint1 = CGPointMake(133, 187); CGPoint controlPoint2 = CGPointMake(174, 318); CGMutablePathRef path = CGPathCreateMutable(); CGPathMoveToPoint(path, NULL, endPointUp.x, endPointUp.y); CGPathAddCurveToPoint(path, NULL, controlPoint1.x, controlPoint1.y, controlPoint2.x, controlPoint2.y, endPointDown.x, endPointDown.y); Any idead how can I achieve this?

• Transmitting Form Data from the Client to the Web Server

  The steps involved in transmitting form data from the client to the web server User loads web form User enters data in to web form fields User clicks submit On submit page validates fields using JavaScript. If validation errors are found then the validation script stops the browser from canceling posting the data to the web server and displays error messages as needed If the form passes the data validation process then the browser will URL encode the values of every field and post it to the server.  The server reads the posted data from the query string and then again validates the data just to ensure data consistency and to prevent any non-validated data because JavaScript was turned off on the clients browser from being inserted in to a database or passed on to other process If the data passes the second validation check then the server side code will continue with the requested processes

• session management: verifying a user's log-in state

  - by good_computer

  I am storing sessions in my database. Everytime a user logs in, I create a new row corresponding to the new session, generate a new session id and send it as a cookie to the browser. My session data looks something like this: { 'user_id': 1234 'user_name': 'Sam' ... } When a request comes, I check whether a cookie with a session id is sent. If it is, I fetch session data from my database (or memcache) corresponding to that session id. When the user logs out, I remove the session data from my database (and memcache), and delete the cookie from the user's browser too. Notice that in my session data, I don't have something like logged_in: true. This is because if I find a session record in the database (or memcache) I deduce that the user is logged in, and if there is no session record found, the user is not logged in. My question is: is this the right approach? Should I have a logged_in key in my session data? Is there any possibility that a session record may be present on the server where the corresponding user is actually NOT logged in? Are there any security implications in having or not having such a key?

• SQL Peer-to-Peer Dynamic Structured Data Processing Collaboration

  Unstructured and XML semi-structured data is now used more than structured data. But fixed structured data still keeps businesses running day in and day out, which requires consistent predictable highly principled processing for correct results. For this reason, it would be very useful to have a general purpose SQL peer-to-peer collaboration capability that can utilize highly principled hierarchical data processing and its flexible and advanced structured processing to support dynamically structured data and its dynamic structured processing. This flexible dynamic structured processing can change the structure of the data as necessary for the required processing while preserving the relational and hierarchical data principles. This processing will perform freely across remote unrelated peer locations anytime and transparently process unpredictable and unknown structured data and data type changes automatically for immediate processing using automatic metadata maintenance.

• Managing arbitrary user permissions under PureFTPd

  - by Sebastián Grignoli

  I need to provide an FTP service that needs to be web-managed in the simplest way possible. My customer wants to create folders and users, and give them read only or read/write access arbitrarily. For example: The folder 'Documents' should be read only for several users, writable for internal users, and invisible for the rest. The folder 'Pictures' should be read only for journalists, writable for associates, and invisible for the rest. The folder 'Media' should be read only, writable or invisible for arbitrary users specified on the admin. There could be a large number of users and folders. I can't find a good way to accomplish that. I thought that I could give each user a home folder and put symlinks for the folders he has read access to, and make the user part of the folder's group when he has write access too, but now I think that this wouldn't work, because with PureFTPd (or ProFTPd) I can only specify the virtual user's mapping to a system user, and only one GUID for each virtual user. My approach requires that I could specify several GUIDs for each user (one by each folder he has write access to). I need to start programming this admin and I still don't know wich approach would work, if any. ¿Any ideas?

• Storing User-uploaded Images

  - by Nyxynyx

  What is the usual practice for handling user uploaded photos and storing them on the database and server? For a user profile image: After receiving the image file from user, rename file to <image_id>_<username> Move image to /images/userprofile Add img filename to a table users containing their profile details like first_name, last_name, age, gender, birthday For a image for a review done by user: After receiving the image file from user, rename file to <image_id>_<review_id> Move image to /images/reviews Add img filename to a table reviews containing their profile details like review_id, review_content, user_id, score. Question 1: How should I go about storing the image filenames if the user can upload multiple photos for a particular review? Serialize? Question 2: Or have another table review_images with columns review_id, image_id, image_filename just for tracking images? Will doing a JOIN when retriving the image_filename from this table slow down performance noticeably? Question 3: Should all the images be stored in a single folder? Will there be a problem when we have 100K photos in the same folder? Is there a more efficient way to go about doing this?

• SQL DB design to support user feeds (in application like facebook)

  - by Yoav

  I have a social network server with a MySql DB. I want to show the users feeds like done in Facebook. Example - UserX now Friend with userY, userX did like on postX etc. Currently I have table: C1 : UserId C2 : LogType (now friend, did like etc) C3 : ObjectId (Can be userId or postId) - set depending on the LogType. Currently to get all related logs to show to the user I do the following queries: 1. Get All user Friends userIds 2. Query all rows which C1 is in userIds (I query completed) 3. Scan the DB and see - if LogType equals DidLike, check if post's OwnerId is the userId - if yes add it to logs. And so on. Obvious this is not efficient at all. I am looking for a better way. I thought I had in mind: Create a new table (in addition to the Log table) C1 : UserId C2 : LogId (from Log table) C3 : UserID of the one who did the action When querying logs - look in the table and get related Logs (by LogId) from LogTable. Updating the table: Whenever user doing action that should be in the log: 1. Add the Log entry to LogTable. 2. Scan the DB and see which users are interested with the Log (Who my friends are, Who is the owner of the post) and add related entries to the new table. (must be done in BG). 3. If user UNFRIEND another user - then look in the logs for all rows where C3 == UNFRIENDED user id and delete them. Any opinions? Other suggestions?

At another part of the code the lister seems to be invoked. Though, there are both Controller types and both us $em->persist($something); $em->flush(); to save the changes. I would expect that in both cases the listener is invoked.

• On a failing hard drive, I am able to view data but unable to copy it - why?

  - by Tom

  I have a 2.5" external hard drive that is failing. It's not making the expected 'clicking' noise that most hard drives and I am able to view the data, but I am unable to actually retrieve the data. I attempted to use SpinRite in order to access the data on the drive, but it didn't like the external drive. When I view the drive's property page, the drive shows that it's used space is at 100% and that it has 0 bytes available; however, the progress indicator under the drive icon in Windows Explorer shows that it's roughly 50% full (which is correct). When I attempt to run Windows' "Error Checking" tool and attempt to "scan for an attempt recovery of bad sectors," the tool begins to run then immediately closes with no error message. I am able to browse the contents of the drive using Windows Explorer. When I begin to try copying any given single file, the copy process begins, an indicator starts, and then the copy fails with no real error message. The Disk Management page in Computer Management under Control Panel also shows this drive has being 'Healthy.' I dropped the drive off at a data recovery store and they said that "The data seems to be intact, but an internal failure is preventing any information from being retrieved." They offered to provide me references to a data recovery specialist. I've also attempted to run CHKDSK on the drive (with and without arguments) but it returns the following error: The type of the filesystem is RAW. CHKDSK is not available for RAW drives. Before going the route of more expensive data recovery, I'm wondering if these symptoms sound familiar to anyone? Other questions... I'm willing to continue trying tools such as TestDisk and/or PhotoRec (as the majority of the data that I'd like to salvage are photos) but how long I should expect either tool to run given approximately 400GB of data? I'm also comfortable using Linux so I welcome any suggestions for utilities or tools and strategies with which you've had success.

• Auth-Type :- Reject in RADIUS users file matches inner tunnel request but sends Access-Accept

  - by mgorven

  I have WPA2 802.11x EAP authentication setup using FreeRADIUS 2.1.8 on Ubuntu 10.04.4 talking to OpenLDAP, and can successfully authenticate using PEAP/MSCHAPv2, TTLS/MSCHAPv2 and TTLS/PAP (both via the AP and using eapol_test). I am now trying to restrict access to specific SSIDs based on the LDAP groups which the user belongs to. I have configured group membership checking in /etc/freeradius/modules/ldap like so: groupname_attribute = cn groupmembership_filter = "(|(&(objectClass=posixGroup)(memberUid=%{User-Name}))(&(objectClass=posixGroup)(uniquemember=%{User-Name})))" and I have configured extraction of the SSID from Called-Station-Id into Called-Station-SSID based on the Mac Auth wiki page. In /etc/freeradius/eap.conf I have enabled copying attributes from the outer tunnel into the inner tunnel, and usage of the inner tunnel response in the outer tunnel (for both PEAP and TTLS). I had the same behaviour before changing these options however. copy_request_to_tunnel = yes use_tunneled_reply = yes I'm running eapol_test like this to test the setup: eapol_test -c peap-mschapv2.conf -a 172.16.0.16 -s testing123 -N 30:s:01-23-45-67-89-01:Example-EAP with the following peap-mschapv2.conf file: network={ ssid="Example-EAP" key_mgmt=WPA-EAP eap=PEAP identity="mgorven" anonymous_identity="anonymous" password="foobar" phase2="autheap=MSCHAPV2" } With the following in /etc/freeradius/users: DEFAULT Ldap-Group == "employees" and running freeradius-Xx, I can see that the LDAP group retrieval works, and that the SSID is extracted. Debug: [ldap] performing search in dc=example,dc=com, with filter (&(cn=employees)(|(&(objectClass=posixGroup)(memberUid=mgorven))(&(objectClass=posixGroup)(uniquemember=mgorven)))) Debug: rlm_ldap::ldap_groupcmp: User found in group employees ... Info: expand: %{7} -> Example-EAP Next I try to only allow access to users in the employees group (regardless of SSID), so I put the following in /etc/freeradius/users: DEFAULT Ldap-Group == "employees" DEFAULT Auth-Type := Reject But this immediately rejects the Access-Request in the outer tunnel because the anonymous user is not in the employees group. So I modify it to only match inner tunnel requests like so: DEFAULT Ldap-Group == "employees" DEFAULT FreeRADIUS-Proxied-To == "127.0.0.1" Auth-Type := Reject, Reply-Message = "User does not belong to any groups which may access this SSID." Now users which are in the employees group are authenticated, but so are users which are not in the employees group. I see the reject entry being matched, and the Reply-Message is set, but the client receives an Access-Accept. Debug: rlm_ldap::ldap_groupcmp: Group employees not found or user is not a member. Info: [files] users: Matched entry DEFAULT at line 209 Info: ++[files] returns ok ... Auth: Login OK: [mgorven] (from client test port 0 cli 02-00-00-00-00-01 via TLS tunnel) Info: WARNING: Empty section. Using default return values. ... Info: [peap] Got tunneled reply code 2 Auth-Type := Reject Reply-Message = "User does not belong to any groups which may access this SSID." ... Info: [peap] Got tunneled reply RADIUS code 2 Auth-Type := Reject Reply-Message = "User does not belong to any groups which may access this SSID." ... Info: [peap] Tunneled authentication was successful. Info: [peap] SUCCESS Info: [peap] Saving tunneled attributes for later ... Sending Access-Accept of id 11 to 172.16.2.44 port 60746 Reply-Message = "User does not belong to any groups which may access this SSID." User-Name = "mgorven" and eapol_test reports: RADIUS message: code=2 (Access-Accept) identifier=11 length=233 Attribute 18 (Reply-Message) length=64 Value: 'User does not belong to any groups which may access this SSID.' Attribute 1 (User-Name) length=9 Value: 'mgorven' ... SUCCESS Why isn't the request being rejected, and is this the right way to implement this?

• C - How to implement Set data structure?

  - by psihodelia

  Is there any tricky way to implement a set data structure (a collection of unique values) in C? All elements in a set will be of the same type and there is a huge RAM memory. As I know, for integers it can be done really fast'N'easy using value-indexed arrays. But I'd like to have a very general Set data type. And it would be nice if a set could include itself.
