• anti-virus / malware solution for small non-profit network

  - by Jason

  I'm an IT volunteer at a local non-profit. I'm looking for a good AV/malware solution. We currently use a mishmash of different client solutions, and want to move to something centralized. There is no full time IT staff. What I'm looking for: centralized administration - server is Windows Server 2003 minimal admin overhead ability to do e-mail notification/alerts/reporting would be very cool 10-25 XP Clients (P3/P4 hardware) free or discounted solution for non-profits We can get a cheap license for Symantec Endpoint Protection. My past experience with Symantec has been bad, but I've heard good things about this product. However, I've also read that it's kind of a nightmare to setup and administer, and may not be worth it for the size of our network.

• haproxy access list using path_dir having issues with firefox

  - by user11243

  I'm trying to route all requests containing a path directory of /socket.io/ to a separate port with HAProxy. Here is my config file: global maxconn 4096 # Total Max Connections.

I've tried clearing cache on firefox and it didn't help, so I'm thinking there's something wrong with the way HAProxy parses through the Firefox request headers.

• IP addresses not updating, but showing correctly in the DHCP Address Leases

  - by Bobby

  I first noticed this when I tried a RDP to wxp-38-shop and it connected me to the computer wxp-alvinm As you can see in the picture I pinged wxp-38-shop and it shows a different IP then whats given in the Address Leases page (w2k3 server). I tried to do ipconfig /flushdns on the server as well as the client computer, but it didn't update that way. If I do an ipconfig on wxp-38-shop is also shows 192.168.0.153, so why when I ping it from any other computer why would it be showing the wrong IP?

• How to handle Real Time Data from a database perspective?

  - by balexandre

  I have an idea in mind, but it still confuses me the database area. Imagine that I want to show real time data, and using one of the latest browser technologies (web sockets - even using older browsers) it is very easy to show to all observables (user browser) what everyone is doing. Remy Sharp has an example about the simplicity about this. But I still don't get the database part, how would I feed, let's imagine (using Remy game Tron) that I want to save the path for each connected user in a database and if a client wants to see what is going on with a 5 sec delay, he will see that, not only the 5 sec until that moment but the continuation in time ... how can I query a DB like that? SELECT x, y FROM run WHERE time >= DATEADD(second, -5, rundate); is not the recommended path right? and pulling this x in x time ... this is not real data feed correct? If can someone help me understand the Database point of view, I would greatly appreciate.

• JSON Support in Azure

  - by kaleidoscope

  Please find how we call JavaScript Object Notation in cloud applications. As we all know how client script is useful in web applications in terms of performance.           Same we can use JQuery in Asp.net using Cloud  computing which will  asynchronously pull any messages out of the table(cloud storage)  and display them in the     browser by invoking a method on a controller that returns JavaScript Object Notation (JSON) in a well-known shape. Syntax : Suppose we want to write a  JQuery function which return some notification while end user interact with our application so use following syntax : public JsonResult GetMessages() {      if (User.Identity.IsAuthenticated)      {     UserTextNotification[] userToasts =           toastRepository.GetNotifications(User.Identity.Name);          object[] data =          (from UserTextNotification toast in userToasts          select new { title = toast.Title ?? "Notification",          text = toast.MessageText }).ToArray();           return Json(data, JsonRequestBehavior.AllowGet);      }         else            return Json(null); } Above function is used to check authentication and display message if user is not exists in Table. Plateform :   ASP.NET 3.5  MVC 1   Under Visual Studio 2008  . Please find below link for more detail : http://msdn.microsoft.com/en-us/magazine/ee335721.aspx   Chandraprakash, S

• Where can I find logs for SFTP?

  - by Jake

  I'm trying to set up sftp-server but the client is getting an error, Connection closed by server with exitcode 1 /var/log/auth.log (below) doesn't help much, how can I find out what the error is? I'm running Ubuntu 10.04.1 LTS sshd[27236]: Accepted password for theuser from (my ip) port 13547 ssh2 sshd[27236]: pam_unix(sshd:session): session opened for user theuser by (uid=0) sshd[27300]: subsystem request for sftp sshd[27236]: pam_unix(sshd:session): session closed for user theuser Update: I've been prodding this for a while now, I've got the sftp command on another server giving me a more useful error. Request for subsystem 'sftp' failed on channel 0 Couldn't read packet: Connection reset by peer Everything I've found on the net suggests this id a problem with sftp-server but when I remove the chroot from sshd config I can access the system. I assume this means sftp-server is accessible and set up correctly.

• Allow READ access to local folders in 2003SBS AD

  - by Dan M.

  Have a SBS2003 client with a mess of a domain that is in process of being cleaned. But, for the life of me I cannot find a setting that will allow write access to the local hard disk for domain users with redirected profiles(to the server). This is needed only for one program that will not follow a symbolic link to the network path, instead it seems to be hard coded to the %appdata% folder but only on the c: drive.... So question is how can I allow "Domain users" write access to the local %appdata% directory? I have tried setting it manually on a machine but it kept resetting to RO no matter how many times I tried. Everytime I would uncheck the RO property it would reset sometime right after i hit OK. Thanks in advance! Dan

• error 0x80070522. not able to create a file in c:\ directory

  - by Abbas

  Hello Everybody... "error 0x80070522. not able to create a file in c:\ directory" One of our customers has just found a problem when trying to create a file on the root of the C:\ Drive, on a Windows 7 Professional PC. I know they shouln't be keeping files here, but there is a valid reason in this case, so I've relaxed the security on the root of C:\ by giving the group 'users' modify permission. Before I relaxed the security, the user was receiving 'access denied', but now they are receiving the message: An unexpected error is keeping you from creating the file. If you continue to recieve this error, you can use the error code to search for help with this problem. Error 0x80070522: A required priviledge is not held by the client. Googling for this suggests that it is caused by UAC, but how can I get round this when the user doesn't have admin rights on their PC? So did you find a solution for this issue ?? Please its urgent to my accountant software..

• Restoring Subversion repositories from backup

  - by John Hoge

  Hi, I had to restore a subversion server from a backup image taken the previous night. Everything worked fine after the restore except for one repository. A working copy had been committed on the server after the latest backup, so this working copy had newer files than the restored repository. I tried to commit the files using tortoise, but SVN didn't recognize that the files on the working copy were newer than those in the repository. I'm using Subversion Server 1.6.5 on Windows 2003 Server and TortoiseSVN 1.6.8 64 bit on a Win7 64 bit client. Thanks, John

• Why is group write permission ignored in Ubuntu?

  - by NorthPole

  I want my user to have full access to the local Apache root folder, and I also want the Apache user to have full access to the same folder. What I did was create a new group called DevGroup and I added my user and www-data there. Also I changed the permissions to 770 to allow full group access. But now it won't allow me or the Apache user any kind of access to the folder. Here is what I get with ls: drwxrwx--- 12 root DevGroup 4096 Sep 27 17:34 testFolder Which seems perfect but when I try as a user to access the file I get this: var/www$ ls testFolder/ ls: cannot open directory testFolder/: Permission denied Also when I try to access a page in the folder from a browser: [Thu Sep 27 17:47:16 2012] [error] [client 127.0.0.1] PHP Fatal error: Unknown: Failed opening required '/var/www/testFolder/foo.php' (include_path='.:/usr/share/php:/usr/share/pear') in Unknown on line 0 What's the problem and how can I fix it?

• Outlook 2007 Clients attachments not opening correctly

  - by Az

  Hello, Thanks for taking the time to read this. We are having an issue on our Terminal Server clients that has me perplexed. We are running Server2003 x64 and Exchange 2007 environment. When we attempt to open an attachment for example .jpeg and the user selects to open the file, it prompts them to select a program to open the file with. The file associations apear to be fine, if I save the document to the desktop and open it, it opens with the correct program automatically. If i select "always open using this program" it will then open automatically, but I don't want to have to do this for all file types we open regularly on each client. Is this some sort of Exchange server security setting that is forcing them to associate the file? Does outlook or exchange maintain its own file association database? Thanks for reading!

• How much the distance and ms can affect on the download speed ?

  - by Prix

  Let's consider A (client) and B (server) where A makes download from B. How much can a bad routing from A to B affect the download speed ? For example A does a tracert to B and get a response of 10 steps where the avg ms is around 300 with 10% packet loss at the 4 step and when the connection is normal the avg from A to B is 10 ~ 30 ms. Could this sort of impact reduce A download speed drasticaly or as long as both side and routes have enough link for the full speed of A from B and vice-versa it should maintain the same speed ? Besides tracert and the ping analyse of A to B what else is used to identify the problem ? If you need extra information please let me know.

• A synergy alternative that just works?

  - by Sridhar Ratnakumar

  I have been using Synergy for a few days now on my Windows 7 desktop (as server) and Macbook (client). Unfortunately, it seems to be buggy - often, the keyboard would stop working on the Mac to the point of forcing me to use the Macbook's keyboard. There are other weird problems as well. Is there a better/proprietary alternative to Synergy? It should support both Windows and Mac. I'd be more than willing to pay for it if it would just work. Edit: How is VNC/TeamViewer supposed to help? I'm not looking to merely access a remote desktop, I only want to share the keyboard/mouse with multiple computers (mac, windows) retaining their own display.

• Browser extension (or other software) to delay page load

  - by Doug Harris

  The alt text to today's comic at xkcd.com (strip below) says: After years of trying, I broke this habit in a day by decoupling the action and the neurological reward. I set up a simple 30-second delay I had to wait through, in which I couldn't do anything else, before any new page or chat client would load (and only allowed one to run at once). The urge to check all those sites magically vanished--and my 'productive' computer use was unaffected. (bold is my emphasis) Does anybody know of a browser extension or other software that will add this sort of delay? I've seen extensions which simply block sites, but not a delay like this.

• Introduction to Oracle ADF

  - by Arda Eralp

  The Oracle Application Development Framework (Oracle ADF) is an end-to-end application framework that builds on Java Platform, Enterprise Edition (Java EE) standards and open-source technologies. You can use Oracle ADF to implement enterprise solutions that search, display, create, modify, and validate data using web, wireless, desktop, or web services interfaces. Because of its declarative nature, Oracle ADF simplifies and accelerates development by allowing users to focus on the logic of application creation rather than coding details. Used in tandem, Oracle JDeveloper 11g and Oracle ADF give you an environment that covers the full development lifecycle from design to deployment, with drag-and-drop data binding, visual UI design, and team development features built in. In line with community best practices, applications you build using the Fusion web technology stack achieve a clean separation of business logic, page navigation, and user interface by adhering to a model-view-controller architecture. MVC architecture: The model layer represents the data values related to the current page The view layer contains the UI pages used to view or modify that data The controller layer processes user input and determines page navigation The business service layer handles data access and encapsulates business logic Each ADF module fits in the Fusion web application architecture. The core module in the framework is ADF Model, a data binding facility. The ADF Model layer enables a unified approach to bind any user interface to any business service, without the need to write code. The other modules that make up a Fusion web application technology stack are: ADF Business Components, which simplifies building business services. ADF Faces rich client, which offers a rich library of AJAX-enabled UI components for web applications built with JavaServer Faces (JSF). ADF Controller, which integrates JSF with ADF Model. The ADF Controller extends the standard JSF controller by providing additional functionality, such as reusable task flows that pass control not only between JSF pages, but also between other activities, for instance method calls or other task flows.

• Distinguishing between UI command & domain commands

  - by SonOfPirate

  I am building a WPF client application using the MVVM pattern that provides an interface on top of an existing set of business logic residing in a library which is shared with other applications. The business library followed a domain-driven architecture using CQRS to separate the read and write models (no event sourcing). The combination of technologies and patterns has brought up an interesting conundrum: The MVVM pattern uses the command pattern for handling user-interaction with the view models. .NET provides an ICommand interface which is implemented by most MVVM frameworks, like MVVM Light's RelayCommand and Prism's DelegateCommand. For example, the view model would expose a number of command objects as properties that are bound to the UI and respond when the user performs actions like clicking buttons. Many implementations of the CQRS use the command pattern to isolate and encapsulate individual behaviors. In my business library, we have implemented the write model as command / command-handler pairs. As such, when we want to do some work, such as create a new order, we 'issue' a command (CreateOrderCommand) which is routed to the command-handler responsible for executing the command. This is great, clearly explained in many sources and I am good with it. However, take this scenario: I have a ToolbarViewModel which exposes a CreateNewOrderCommand property. This ICommand object is bound to a button in the UI. When clicked, the UI command creates and issues a new CreateOrderCommand object to the domain which is handled by the CreateOrderCommandHandler. This is difficult to explain to other developers and I am finding myself getting tongue-tied because everything is a command. I'm sure I'm not the first developer to have patterns overlap like this where the naming/terminology also overlap. How have you approached distinguishing your commands used in the UI from those used in the domain? (Edit: I should mention that the business library is UI-agnostic, i.e. no UI technology-specific code exists, or will exists, in this library.)

• VirtualBox "Bridged Adapter" when host NIC is turned off

  - by chris_l

  Hi, I'm running Linux (Debian Etch) in a VirtualBox VM on my MacBook. I usually ssh from my Mac terminal to the guest machine. I also want to access the internet from my guest, so I set up my host's WLAN card (en1) as a bridged adapter for eth0 on the client. This works fine, but when I turn off the WLAN card (e.g. to reduce battery consumption), I'd still like to ssh from my host to the guest. This fails of course, because en1 loses its IP address. Is a bridged adapter the best option for what I want to do? How can I make it work? (A simple "ifconfig en1 add 10.0.0.4" didn't do the trick...) Thanks Chris

• IRC "proxy" for persistent connection between several computers

  - by Zeta Two

  I'm looking for a program that enables me to stay connected to one or more IRC networks and be able to view the log even though I connect from several different computers. I'm thinking about something like a proxy running on a server who always is connected to the servers/channels I want and to which I connect from whichever client I want to use. Does anyone know of a program like this? Edit: Apparently I could be running a IRC session in a shell on a server and connect to this but I would like something more GUI:ish.

• website attack form submission triggering emails related questions

  - by IberoMedia

  We are experiencing website attacks that trigger the submission of a form, and send alert emails. Normal process of form submission is to fill up a couple of text fields, and when the user is redirected, the next page processes $_POST. If $_POST exists, then the email to intended form recipients is triggered. What is happening right now, we are receiving the email of the form submission, three emails at a time with same information. The information per email is the same, but not all of the spam emails contain the same information, each batch of triggered emails has unique information. The form has no captcha, and if possible we would like to keep it this way. The website has worked fine and had no spamming problems until today. We have monitoring software for the website, but whoever is submitting this form over and over is not being recorded by the tracking software WHY IS THIS? IS THE PERSON ACTUALLY VISITING THE WEBSITE? The only suspicious visit tracked was on November 10th, and this record ALSO shows three forms submitted (this is how I identified possible first visit by attacker). Then no incidents until today. WHAT IS THE GOAL of the spam attack? Is the attacker expecting us to respond to the bogus emails? What can they achieve with repeated submission of form Why are three emails triggered in the row? Is this indicative that they may be using a script? This is a PHP website. Is there a way for a client to view the PHP code of a page? Thank you
