  • Creating static NAT blocks outbound traffic Cisco ASA

    - by natediggs
    Hi Everyone, I have two web servers sitting behind a Cisco ASA 5505, which I don't have much experience with. I'm trying to create two static NATs. One static NAT that goes to xx.xx.xx.150 and another that goes to xx.xx.xx.151. I've created the static NAT for the .150 web server and it works FINE. Incoming and outgoing traffic work great. This is the staging web server. I now need to duplicate the setup for the production web server. So, I connect the webserver to the firewall, change the public IP address on one of the NICs reboot the server and I have outbound internet access. Then I run the command: static (inside,outside) xx.xx.xx.150 192.168.1.x which is successful. I then run the command: access-list acl-outside permit tcp any host xx.xx.xx.150 eq 80 Which is successful. I then try to browse the internet and I get nothing. I try to telnet in through port 80 and I get nothing (though I'm guessing because the response to the telnet request is being blocked). I've tried this with the production web server and then I tried it with another web server that is for internal testing and have the exact same problem. Both work fine until I run the static NAT rule and then no outbound internet access. I have a feeling that it's something simple that I'm missing, but my limited experience with this device is killing me. Below I've pasted the current configuration. I'm currently trying to get this to work on the .153 server which is the internal testing server. Once I can verify that works, I'll try it with production. : Saved : ASA Version 8.2(4) ! hostname QG domain-name XX.com enable password passwd names ! interface Ethernet0/0 switchport access vlan 2 !

  • Cisco ASA: Allowing and Denying VPN Access based on membership to an AD group

    - by milkandtang
    I have a Cisco ASA 5505 connecting to an Active Directory server for VPN authentication. Usually we'd restrict this to a particular OU, but in this case users which need access are spread across multiple OUs. So, I'd like to use a group to specify which users have remote access. I've created the group and added the users, but I'm having trouble figuring out how to deny users which aren't in that group. Right now, if someone connects they get assigned the correct group policy "companynamera" if they are in that group, so the LDAP mapping is working. However, users who are not in that group still authenticate fine, and their group policy becomes the LDAP path of their first group, i.e. CN=Domain Users,CN=Users,DC=example,DC=com, and then are still allowed access. How do I add a filter so that I can map everything that isn't "companynamera" to no access? Config I'm using (with some stuff such as ACLs and mappings removed, since they are just noise here): gateway# show run : Saved : ASA Version 8.2(1) ! hostname gateway domain-name corp.company-name.com enable password gDZcqZ.aUC9ML0jK encrypted passwd gDZcqZ.aUC9ML0jK encrypted names name 192.168.0.2 dc5 description FTP Server name 192.168.0.5 dc2 description Everything server name 192.168.0.6 dc4 description File Server name 192.168.0.7 ts1 description Light Use Terminal Server name 192.168.0.8 ts2 description Heavy Use Terminal Server name 4.4.4.82 primary-frontier name 5.5.5.26 primary-eschelon name 172.21.18.5 dmz1 description Kerio Mail Server and FTP Server name 4.4.4.84 ts-frontier name 4.4.4.85 vpn-frontier name 5.5.5.28 ts-eschelon name 5.5.5.29 vpn-eschelon name 5.5.5.27 email-eschelon name 4.4.4.83 guest-frontier name 4.4.4.86 email-frontier dns-guard !

    - by karlthorwald
    Does watir's browser.text.include? count text inside invisible divs? If so, how to search only for visible text? I put all the instructions into the html from the beginning and use jQuery to hide and unhide the relevant parts. How can I use watir's waiter to wait for only text that is visible? My problem is, that the waiter always returns true, even before I have shown a certain text.

  • Help with chat server

    - by mithun1538
    I am designing a chat server in java. The communication is Http based and not socket based. In the client side I have an applet. In the server side I have a servlet. Applet: I create a new thread to listen for incoming messages(GET method). The main thread is used to send messages(POST messages). The partial code is : public void start() { System.out.println("Creating new thread"); Thread thread = new Thread(this); thread.start(); } private String getNewMessage() { System.out.println("Inside getNewMessage"); String msg = null; try { while(msg == null) { System.out.println("Trying to listen to servlet"); URL servlet = new URL(getCodeBase(), "NewServlet?mode=msg"); URLConnection con = servlet.openConnection(); con.setUseCaches(false); DataInputStream din = new DataInputStream(new BufferedInputStream(con.getInputStream())); msg = din.readUTF(); System.out.println("message read :" + msg); } } catch (Exception e) { e.printStackTrace(); } return msg + "\n"; } public void run() { System.out.println("Inside new thread"); while(true) { System.out.println("inside first while"); String newMsg = getNewMessage(); chatOutput.append(newMsg); System.out.println("Appended!!"); } } private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) { String message = chatInput.getText(); chatInput.setText(""); chatOutput.append(message + "\n"); try { System.out.println("Trying to send msg :" + message); URL url = new URL(getCodeBase(), "NewServlet"); URLConnection servletConnection = url.openConnection(); servletConnection.setDoInput(true); servletConnection.setDoOutput(true); servletConnection.setUseCaches(false); servletConnection.setRequestProperty("Content-Type", "application/octet-stream"); ObjectOutputStream out = new ObjectOutputStream(servletConnection.getOutputStream()); out.writeObject(message); out.flush(); out.close(); System.out.println("Message sent!"); } catch (Exception e) { e.printStackTrace(); } } This next code is from the servlet side. it uses the Observable interface to identify and send messages to clients. public class NewServlet extends HttpServlet { // getNextMessage() returns the next new message. // It blocks until there is one. public String getNextMessage() { // Create a message sink to wait for a new message from the // message source. System.out.println("inside getNextMessage"); return new MessageSink().getNextMessage(source);} @Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { System.out.println("Inside Doget"); response.setContentType("text/plain"); PrintWriter out = response.getWriter(); out.println(getNextMessage()); } // broadcastMessage() informs all currently listening clients that there // is a new message.

String messageCopy = message; message = null; System.out.println("Returning msg"); return messageCopy; } } As you can see I have included System.out.println("Some message"); in some places. this was just for debugging purposes. In java console, i get the following output: Creating new thread Inside new thread. inside first while. Inside getNewMessage. Trying to listen to servlet. In the servlet side, i get the following output in the tomcat logs: Inside Doget. inside getNextMessage. AddedObserver. After i type a message in the applet, and send it, I get the foll output in java console: Trying to send msg :you deR?? Message sent! But in servlet side, I dont get anything in the logs. I used the O'Reily Java Servlet Programming as reference(The observer interface comes from there). But I am not getting any chat communication between two clients. As can be understood from the logs, the POST method is not called. Any reason for this?

  • Rails logger messages test.log?

    - by Dave Paroulek
    Is it possible to configure rails to show logger.debug messages (from logger.debug statements inside controllers) to display inside test.log (or to the console) when running unit and functional tests? I added the following to test_helper.rb. I see messages from logger.debug statements directly inside tests but no messages from logger statements inside controller methods? def logger RAILS_DEFAULT_LOGGER end

  • javascript Refresh Div.

    - by Tom
    Hi, I am using this code to refresh the data inside of the div: <script> $(function() { $("#refresh").click(function() { $("#new").load("/new.php") }) }) </script> Except it loads the who page inside of the div, instead of just the information that is inside of the div. How do I make it refresh only the data that is inside of the div? Is there a way of doing it other than putting the information for that div in a seperate page?

  • Why is Swing Parser's handleText not handling nested tags?

    - by Jim P
    I need to transform some HTML text that has nested tags to decorate 'matches' with a css attribute to highlight it (like firefox search). I can't just do a simple replace (think if user searched for "img" for example), so I'm trying to just do the replace within the body text (not on tag attributes). I have a pretty straightforward HTML parser that I think should do this: final Pattern pat = Pattern.compile(srch, Pattern.CASE_INSENSITIVE); Matcher m = pat.matcher(output); if (m.find()) { final StringBuffer ret = new StringBuffer(output.length()+100); lastPos=0; try { new ParserDelegator().parse(new StringReader(output.toString()), new HTMLEditorKit.ParserCallback () { public void handleText(char[] data, int pos) { ret.append(output.subSequence(lastPos, pos)); Matcher m = pat.matcher(new String(data)); ret.append(m.replaceAll("<span class=\"search\">$0</span>")); lastPos=pos+data.length; } }, false); ret.append(output.subSequence(lastPos, output.length())); return ret; } catch (Exception e) { return output; } } return output; My problem is, when I debug this, the handleText is getting called with text that includes tags! It's like it's only going one level deep. Anyone know why? Is there some simple thing I need to do to HTMLParser (haven't used it much) to enable 'proper' behavior of nested tags? PS - I figured it out myself - see answer below. Short answer is, it works fine if you pass it HTML, not pre-escaped HTML. Doh! Hope this helps someone else. <span>example with <a href="#">nested</a> <p>more nesting</p> </span> <!-- all this gets thrown together -->

  • Dojo Datagrid Filtering Issue

    - by Zoom Pat
    I am having hard time filtering a datagrid. Please help! This is how I draw a grid. var jsonStore = new dojo.data.ItemFileWriteStore({data:columnValues}); gridInfo = { store: jsonStore, queryOptions: {ignoreCase: true}, structure: layout }; grid = new dojox.grid.DataGrid(gridInfo, "gridNode"); grid.startup(); Now if i try something like this, it works fine and gives me the rows which has the column (AGE_FROM) value equal to 63. grid.filter({AGE_FROM:63}); but I need all kinds of filtering and not just 'equal to' So how do I try to obtain all the rows which have AGE_FROM 63, and < 63 and <= 63 and =63. because grid.filter({AGE_FROM:<63}); does not work Also One other way I was thingking was to use the following filteredStore = new dojox.jsonPath.query(filterData,"[?(@.AGE_FROM = 63]"); and then draw the grid with the filteredStore, but the above is not working for a != operator. Once I figure a good way to filter grid I need to see a way to filter out dates. I am trying to find a good example for filtering dataGrid but most of the examples are just filtering based on the 'equal to' criteria. Any help is highly appreciated.

  • Returning to last viewed List page after insert/edit with ASP.NET Dynamic Data

    - by Pat James
    With a pretty standard Dynamic Data site, when the user edits or inserts a new item and saves, the page does a Response.Redirect(table.ListActionPath), which takes the user back to page 1 of the table. If they were editing an item on page 10 (or whatever) and want to edit the next item on that page, they have to remember the page number and navigate back to it. What's the best way to return the user to the list page they last viewed? I can conceive of some solutions using cookies, session state, or query string values to retain this state and making my own Page Template to incorporate it, but I can't help thinking this must be something that was considered when Dynamic Data was created, and there must be something simpler or built-in to the framework that I'm missing here.

  • Excel VBA Text To Column

    - by Pat
    This is what I currently have: H101 John Doe Jane Doe Jack Doe H102 John Smith Jane Smith Katie Smith Jack Smith And here is what I want: H101 John Doe H101 Jane Doe H101 Jack Doe H102 John Smith H102 Jane Smith H102 Katie Smith H102 Jack Smith Obviously I want to do this on a bigger scale. The number of columns is between 1 & 6, so I cant limit it that way. I was able to get a script that allows me to put each individual on one row. However, I am having a hard time getting the first column to copy over to each row. Sub ToOneColumn() Dim i As Long, k As Long, j As Integer Application.ScreenUpdating = False Columns(2).Insert i = 0 k = 1 While Not IsEmpty(Cells(k, 3)) j = 3 While Not IsEmpty(Cells(k, j)) i = i + 1 Cells(i, 1) = Cells(k, 1) //CODE IN QUESTION Cells(i, 2) = Cells(k, j) Cells(k, j).Clear j = j + 1 Wend k = k + 1 Wend Application.ScreenUpdating = True End Sub Like I said, it was working fine to get everyone each on their own row, but can't figure out how to get that first column. It seems like it should be so simple, but it's bugging me. Any help is greatly appreciated.

  • Marshalling a big-endian byte collection into a struct in order to pull out values

    - by Pat
    There is an insightful question about reading a C/C++ data structure in C# from a byte array, but I cannot get the code to work for my collection of big-endian (network byte order) bytes. (EDIT: Note that my real struct has more than just one field.) Is there a way to marshal the bytes into a big-endian version of the structure and then pull out the values in the endianness of the framework (that of the host, which is usually little-endian)? This should summarize what I'm looking for (LE=LittleEndian, BE=BigEndian): void Main() { var leBytes = new byte[] {1, 0}; var beBytes = new byte[] {0, 1}; Foo fooLe = ByteArrayToStructure<Foo>(leBytes); Foo fooBe = ByteArrayToStructureBigEndian<Foo>(beBytes); Assert.AreEqual(fooLe, fooBe); } [StructLayout(LayoutKind.Explicit, Size=2)] public struct Foo { [FieldOffset(0)] public ushort firstUshort; } T ByteArrayToStructure<T>(byte[] bytes) where T: struct { GCHandle handle = GCHandle.Alloc(bytes, GCHandleType.Pinned); T stuff = (T)Marshal.PtrToStructure(handle.AddrOfPinnedObject(),typeof(T)); handle.Free(); return stuff; } T ByteArrayToStructureBigEndian<T>(byte[] bytes) where T: struct { ??? }

  • Override the default row error behavior for a DataGridView

    - by Pat
    I have a DataGridView that is bound to a DataTable. When a row in the table has an error (row.RowError is not empty), the DGV helpfully displays an error icon and tooltip with the error text. Instead of, or in addition to, this behavior, I would like to change the entire row color. What event does the DGV subscribe to in order to handle errors and/or how can I override the DGV's default behavior?

  • Conditionals in Antlr String Templates

    - by Pat Long - Munkii Yebee
    We are using Antlr StringTemplates to give control over how a Entity's Name is output. The basic Stringtemplate is $FirstName$ $Initial$ $LastName$, $Suffix$, $Degree$ I want to add some smarts to that template so that the commas are only output when necessary i.e. The first comma is only output when there is a Suffix or Degree and the second commas is only output if there is a suffix. I tried the following template string bit it does not work. I guess I have misunderstood $FirstName$ $Initial$ $LastName$ <if(Suffix|Degree)>,<endif>, $Suffix$ <if(Suffix)>,<endif> $Degree$ If it helps we process the templates using this C# StringTemplate stringtemplate = new Antlr.StringTemplate.StringTemplate(template.Data); foreach (Pair<string, string> pair in dictionary) { if (pair.First != null && pair.Second != null) { stringtemplate.SetAttribute(pair.First, pair.Second); } } return stringtemplate.ToString();

  • jCarousel, IE6 and Fixed Width

    - by Pat Long - Munkii Yebee
    We are using jCarousel on our websites to display images. Simple enough. We have fairly flexible layouts so the carousels are not always the same width. FF, IE7+, Chrome, Safari etc work perfectly well taking up the space available. However IE6 ends up sending the jCarousel script into a loop and warns that a script is stopping the page from loading correctly. To stop IE6 from failing we are having to specify a fixed width in CSS for the carousel container. Is this a problem that others have had with IE6 and jCarousel?

  • Easiest way to retrofit retry logic on LINQ to SQL migration to SQL Azure

    - by Pat James
    I have a couple of existing ASP .NET web forms and MVC applications that currently use LINQ to SQL with a SQL Server 2008 Express database on a Windows VPS: one VPS for both IIS and SQL. I am starting to outgrow the VPS's ability to effectively host both SQL and IIS and am getting ready to split them up. I am considering migrating the database to SQL Azure and keeping IIS on the VPS. After doing initial research it sounds like implementing retry logic in the data access layer is a must-do when adopting SQL Azure. I suspect this is even more critical to implement in my situation where IIS will be on a VPS outside of the Azure infrastructure. I am looking for pointers on how to do this with the least effort and impact on my existing code base. Is there a good retry pattern that can be applied once at the LINQ to SQL data access layer, as opposed to having to wrap all of my LINQ to SQL operations in try/catch/wait/retry logic?

  • 301 redirect vs parking

    - by Pat
    I have several domain names registered, each a slight variant of each other. E.g, fastcar.com fast-car.com fastcar.co.uk fast-car.co.uk etc.. I don't wish to be penalized for duplicate content or spammy links by any of the major search engines. Should I park them all directly on the main domain I wish to promote, 301 redirect them to the main domain or not use them at all? Thanks

  • Hybrid EAV/CR model via WCF (and statically-typed language)?

    - by Pat
    Background I'm working on the architecture for a cloud-based LOB application, using Silverlight for the client, WCF, ASP.NET/C# for server and SQL Server for storage. The data model requires some flexibility per user (ability to add custom properties and define validation rules for them, for example), and a hybrid EAV/CR persistence model on the server side will suit nicely. Problem I need an efficient and maintainable technology and approach to handle the transformation from the persisted EAV model to/from WCF (and similarly allow the client to bind to the resulting data - DataGrid is a key UI element)? Admission: I don't yet know enough about WCF to understand if it supports ExpandoObject directly, but I suspect it will. Options I started off looking at WCF RIA services, but quickly discovered they're heavily dependent upon both static type data and compile-time code generation. Neither of these appeal. The options I'm considering include: Using WCF RIA services and pass the data over the network directly in EAV form (i.e. Dictionary), and handle the binding issue purely on the client side (like this) Using a dynamic language (probably IronPython) to handle both ends of the communication, with plumbing to generate the necessary CLR type data on the client to allow binding, and transform to/from EAV form on the server (spam preventer stopped me from posting a URL here, I'll try it in a comment). Dynamic LINQ (CreateClass() and friends), although I'm way out of my depth there and don't know what the limitations on that approach might be yet. I'm interested in comments on these approaches as well as alternative approaches that might solve the problem. Other Notes The Silverlight client will not be the only consumer of the service, making me slightly uncomfortable with option #1 above. While the data model is flexible, it's not expected to be modified heavily. For argument's sake, we could assume that we might have 25 distinct data models active at a given time, with something like 10-20 unique data fields/rules each. Modifications to the data model will happen infrequently (typically when a new user is initially configured).

  • Using Custom MapType with Google Maps API

    - by Pat Long - Munkii Yebee
    I realise there are a couple of examples such as Maoki's Add Your Own Custom Map and Mike Williams' [link text][Google Maps API Tutorial] however I have looked at these and still end up with a Grey box. The API will not call my "getTileUrl" callback function. This is the javascript I am using var map = new GMap2(document.getElementById("map")); map.setUIToDefault(); var copyCollection = new GCopyrightCollection('Map Data:'); var copyright = new GCopyright(1, new GLatLngBounds(new GLatLng(-90, -180), new GLatLng(90, 180)), 0, "©2006 RunwayFinder.com"); copyCollection.addCopyright(copyright); var tilelayers = [new GTileLayer(copyCollection, 3, 11)]; tilelayers[0].getTileUrl = function (a, b) { var z = 17 - b; var f = "http://localhost:25213/test.jpg?x=" + a.x + "&y=" + a.y + "&zoom=" + z + "&width=100&height=100"; return f; }; var custommap = new GMapType(tilelayers, new GMercatorProjection(12), "Chart", { errorMessage: "No chart data available" }); map.addMapType(custommap); Can anyone see what it is i am doing wrong?

  • Tool to generate a GUI (WinForms or WPF) from a class.

    - by Pat
    Say we've got a class like public class Doer { public int Timeout {get;set;} public string DoIt(string input) { string toReturn; // Do something that involves a Timeout return toReturn; } } Is there a tool that would create a Form or Control for prototyping this class? The GUI might have a NumericUpDown control with a label of "Timeout" and a GroupBox with a TextBox for "input" and a button labeled "DoIt" with an eventhandler that calls Doer.DoIt with the Text property of the input TextBox and puts the response in another TextBox.
