  • Cisco ASA and static IPv6 tunnel endpoint?

    - by Martijn Heemels
    I recently installed a Cisco ASA 5505 firewall on the edge of our LAN. The setup is simple: Internet <-- ASA <-- LAN I would like provide the hosts in the LAN with IPv6 connectivity by setting up a 6in4 tunnel to SixXS. It would be nice to have the ASA as tunnel endpoint so it can firewall both IPv4 and IPv6 traffic. Unfortunately the ASA apparently can't create a tunnel itself, and can't port-forward protocol 41 traffic, so I believe I would have to do one of the following instead: Set up a host with it's own IP outside the firewall, and have that function as tunnel-endpoint. The ASA can then firewall and route the v6 subnet to the LAN. Set up a host inside the firewall that functions as endpoint, separated via vlan or whatever, and loop the traffic back into the ASA where it can be firewalled and routed. This seems contrived, but would allow me to use a VM instead of a physical machine as endpoint. Any other way? What would you suggest is the optimal way to set this up? P.S. I do have a spare public IP address available if needed, and can spin up another VM in our VMware infrastructure.

  • Windows 7 starts getting sluggish over a few days

    - by munrobasher
    Myself and the other developer are running Windows 7 Enterprise 64 bit with 8GB RAM on different Gigabyte motherboards with Quad core Intel CPUs. Most of the time, it runs like a dream. We use VMware workstation a lot (hence the 8GB) and that works well. Except... now and then, after the PCs have been on for a few days, the whole system starts getting really sluggish doing certain tasks. The other's developer's system is far worse than mine with it taking up to a minute to launch IE. Today, mine has gone sluggish but nowhere near as bad. For example, normally when I click on a new tab in IE, it's instant. Today, there's an obvious delay. Right-clicking in this window to trigger iSpell is normally instant, right now it takes about five seconds. I've got resource monitor open on my second monitor and when I did that right-click, there was no obvious peak in CPU, disk or memory. A reboot does fix it so it does sound like a resource issue but haven't a clue what might be to blame. The two computers have similarities (same spec) but also differences (like motherboard, RAM & CPU models). So I guess the question is, any pointers on diagnosing why a PC is sluggish? What could cause such a right-click slow down in IE for example? It sounds like such a simple operation. NOTE: whilst typing this message alone, it was fine performance wise. I can click around the page no problem but right-click still is noticeable slow. Will reboot over lunch... Cheers, Rob.

  • Ignoring SEO Information

    The Internet is filled with so much of information about the SEO and web marketing. The concept of blogging and writing articles has come up only for the reason that everyone looks for only latest content in the industry. Regrettably it is a fact that both the true and the untrue SEO persons write the same amount of articles.

  • How can I create a SQL table using excel columns?

    - by Phsika
    I need to help to generate column name from excel automatically. I think that: we can do below codes: CREATE TABLE [dbo].[Addresses_Temp] ( [FirstName] VARCHAR(20), [LastName] VARCHAR(20), [Address] VARCHAR(50), [City] VARCHAR(30), [State] VARCHAR(2), [ZIP] VARCHAR(10) ) via C#. How can I learn column name from Excel? private void Form1_Load(object sender, EventArgs e) { ExcelToSql(); } void ExcelToSql() { string connectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Source\MPD.xlsm;Extended Properties=""Excel 12.0;HDR=YES;"""; // if you don't want to show the header row (first row) // use 'HDR=NO' in the string string strSQL = "SELECT * FROM [Sheet1$]"; OleDbConnection excelConnection = new OleDbConnection(connectionString); excelConnection.Open(); // This code will open excel file. OleDbCommand dbCommand = new OleDbCommand(strSQL, excelConnection); OleDbDataAdapter dataAdapter = new OleDbDataAdapter(dbCommand); // create data table DataTable dTable = new DataTable(); dataAdapter.Fill(dTable); // bind the datasource // dataBingingSrc.DataSource = dTable; // assign the dataBindingSrc to the DataGridView // dgvExcelList.DataSource = dataBingingSrc; // dispose used objects if (dTable.Rows.Count > 0) MessageBox.Show("Count:" + dTable.Rows.Count.ToString()); dTable.Dispose(); dataAdapter.Dispose(); dbCommand.Dispose(); excelConnection.Close(); excelConnection.Dispose(); }

  • iOS Question. Is There a Framework for Build Time Based Apps.

    - by dugla
    I have the need for some time based effects in the iPad app I am building. The UIView class animation capability beginAnimatins/commitAnimations is exactly the sort of thing I am looking for but it is restricted to specific properties of UIView deemed animatable. Ideally, I am looking for a solution that lets me drive an a time-based function that can perhaps send messages to a class of my own choosing at the rate I specify in the animation. Specifically, I have a function - my implementation of the RenderMan function "smoothstep" which is essentially an ease-in ease-out curve common in animation. It takes [0 - 1] as input and outputs [0 - 1] as the curve is evaluated. I want to drive this function for a duration of my own choosing at rate of my own choosing. Thanks in advance. -Doug

  • From string to hex MD5 hash and back

    - by Pablo Fernandez
    I have this pseudo-code in java: bytes[] hash = MD5.hash("example"); String hexString = toHexString(hash); //This returns something like a0394dbe93f bytes[] hexBytes = hexString.getBytes("UTF-8"); Now, hexBytes[] and hash[] are different. I know I'm doing something wrong since hash.length() is 16 and hexBytes.length() is 32. Maybe it has something to do with java using Unicode for chars (just a wild guess here). Anyways, the question would be: how to get the original hash[] array from the hexString. The whole code is here if you want to look at it (it's ~ 40 LOC) http://gist.github.com/434466 The output of that code is: 16 [-24, 32, -69, 74, -70, 90, -41, 76, 90, 111, -15, -84, -95, 102, 65, -10] 32 [101, 56, 50, 48, 98, 98, 52, 97, 98, 97, 53, 97, 100, 55, 52, 99, 53, 97, 54, 102, 102, 49, 97, 99, 97, 49, 54, 54, 52, 49, 102, 54] Thanks a lot!

  • Dates search in Drupal (greater than, less than) using CCK / views / facelet?

    - by guillefar
    I'm working in a site that manage events (like parties). Each event could have several fields, including date, that the user could add thanks to CCK module. Now, the problem is when I have to search using those fields. I could not find how to search for events between a range of dates. I discover the facelet module, which is pretty good, and it is very useful for some kind of search, but as far as I can see it is not possible search in a range. Also I do some testing using views, but again, with no results. I can not find how to search a date "greater than" and "less than". I will really appreciate any help.

  • Chrome and Safari strange behaviour in Javascript

    - by mck89
    Hi, i've written this peace of code: var a=function(){ }; a.name="test"; a.prop="test2"; Now if i debug the code with the console: console.log(a.name); console.log(a.prop); In Firefox i get a.name="test" and a.prop="test2", while in Safari and Chrome i get a.prop="test2" but a.name="". It seems that there's no way to assign a "name" property on a function in Webkit browsers. Do you know why? But the most important thing is, do you know a workaround for that?

  • Rails: translate ActiveRecord error template headers for a single model

    - by Chris
    Hi, I'm trying to rename the authlogic error messages in a Rails 3 app. The general format I found out working in Rails 3: de: errors: template: header: one: "Konnte {{model}} nicht speichern: ein Fehler." other: "Konnte {{model}} nicht speichern: {{count}} Fehler." body: "Bitte überprüfen Sie die folgenden Felder: But I want to change this for the authlogic user session model (and only for this one) because when the Login fails, the message "Could not save user session" does not make very much sense. How can I do that?

  • Improving field get and set performance with ASM

    - by ng
    I would like to avoid reflection in an open source project I am developing. Here I have classes like the following. public class PurchaseOrder { @Property private Customer customer; @Property private String name; } I scan for the @Property annotation to determine what I can set and get from the PurchaseOrder reflectively. There are many such classes all using java.lang.reflect.Field.get() and java.lang.reflect.Field.set(). Ideally I would like to generate for each property an invoker like the following. public interface PropertyAccessor<S, V> { public void set(S source, V value); public V get(S source); } Now when I scan the class I can create a static inner class of PurchaseOrder like so. static class customer_Field implements PropertyAccessor<PurchaseOrder, Customer> { public void set(PurchaseOrder order, Customer customer) { order.customer = customer; } public Customer get(PurchaseOrder order) { return order.customer; } } With these I totally avoid the cost of reflection. I can now set and get from my instances with native performance. Can anyone tell me how I would do this. A code example would be great. I have searched the net for a good example but can find nothing like this. The ASM examples are pretty poor also. The key here is that I have an interface that I can pass around. So I can have various implementations, perhaps one with Java Reflection as a default, one with ASM, and maybe one with Javassist? Any help would be greatly appreciated.

  • Why won't VS2010 RC use my existing types when I add a service reference?

    - by Johan Driessen
    I have a huge problem getting services references in VS2010 RC to use existing assemblies. Even though I have a class library with all the data contracts (classes marked with DataContract and properties with DataMember) that is shared between the service project and the consuming project (which is a class library), when I add a service reference, the data contracts are regenerated withing the service reference instead of using the existing types. When I was using VS2010 beta 2, this worked fine, and I have existing service references using the very same data contracts. But if I add a new service reference, or even update an old one, it won't use the existing types anymore. I have made a mini-test-solution, with one service, one data contract type and one console app as a consumer (all in the same solution), and there it seems to work, but that's no great comfort to me. Is there any way to see why it can't use the existing types? Edit to clearify. It works to generate the proxy classes with svcutil.exe, and point to the data contracts dll, like this: svcutil.exe http://localhost/MyService.svc /reference:[Path To DataContracts]\DataContracts.dll /n:*,MyProject.MyServiceReference /ct:System.Collections.Generic.List`1 The question is, what possible reason could there be for Visual Studio to generate its own datacontracts instead of using the existing ones even though the "reuse" checkbox is checked and the datacontracts assembly is referenced.

  • PHP sorting issue with simpleXML

You can see that in the array I can make it sort by the attribute 'statename'. What I am having trouble with is echoing out and combining the two functions in order to have it auto sort both the states and the cities within and forming the needed optgroups. I tried copying the lines for the cities and changing the names called several ways to no avail.

  • JAXB Unable To Handle Attribute with Colon (:) in name?

    - by Intellectual Tortoise
    I am attempting to use JAXB to unmarshall an XML files whose schema is defined by a DTD (ugh!). The external provider of the DTD has specified one of the element attributes as xml:lang: <!ATTLIST langSet id ID #IMPLIED xml:lang CDATA #REQUIRED > This comes into the xjc-generated class (standard generation; no *.xjb magic) as: @XmlAttribute(name = "xml:lang", required = true) @XmlJavaTypeAdapter(NormalizedStringAdapter.class) protected String xmlLang; However, when unmarshalling valid XML files with JAXB, the xmlLang attribute is always null. When I edited the XML file, replacing xml:lang with lang and changed the @XmlAttribute to match, unmarshalling was successful (i.e. attributes were non-null). I did find this http://old.nabble.com/unmarshalling-ignores-element-attribute-%27xml%27-td22558466.html. But, the resolution there was to convert to XML Schema, etc. My strong preference is to go straight from an un-altered DTD (since it is externally provided and defined by an ISO standard). Is this a JAXB bug? Am I missing something about "namespaces" in attribute names? FWIW, java -version = "build 1.6.0_20-b02" and xjc -version = "xjc version "JAXB 2.1.10 in JDK 6""

    What is a good light weight JavaScript IDE? I don't care too much for the one built into VS because it seams lacking. I've been using 1st JavaScript Editor Pro as a alternative for working with JavaScript but I wanted to see if there is any thing else out there that is better and light weight.
