Cisco Certification: Making A Good Impression In Your Job Interview

People who pass the CCNA exam fall into one of three categories. You may be just entering the IT field you may be working on the LAN side and want to move to the WAN side (that’s where I was when I passed the CCNA), or you may already work on the WAN side of the network, and you want to move up the ladder.

Phishing with a Net

Being hacked or being cracked makes little difference to those on the receiving end. Understandably, their first impulses are to get mad and want to vent. The Cyberiter’s contention is that, most of the time, they’re lashing out in the wrong direction. After all, crooks are crooks; that’s their job. Prevention is your job, so know the fundamentals of diligence.

What are browser hijackers?

If you are one of the millions of people who have suffered a browser hijacking, you likely know it, and you clearly remember what you were doing when it happened. The best known form of browser hijacking is when a sudden flood of pop-ups, many of them obscene, explode over your screen and you are forced to use the CTRL-ATL-DEL sequence to close your browser and regain control of your computer.

b-PAC Application Examples [ Print from Web Application]

This article explains the system configuration and coding examples to print Brother labels from the web. If you’ve ever tried to work with the Brother software SDK you definitely would have reached a point where you feel true frustration with the lack of documentation and samples from 2003 written in VBS and Visual Studio 2003 (that don’t even compile anymore).

How to Add xml:lang=”en-GB” to XmlTextWriterSettings

I’ve written in the past about XML & languages, and why you might be interested in being aware of the language associated with text. xml:lang is your friend, as you can tell from these older posts.

Something that is a bit special about xml:lang is that xml is a reserved namespace. From http://www.w3.org/TR/REC-xml-names/#xmlReserved

The prefix xml is by definition bound to the namespace name http://www.w3.org/XML/1998/namespace. It MAY, but need not, be declared, and MUST NOT be bound to any other namespace name. Other prefixes MUST NOT be bound to this namespace name, and it MUST NOT be declared as the default namespace.

Here is the code you can use to write an xml:lang attribute.

XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = 
true;

using
 (StringWriter textWriter = new StringWriter())
using (XmlWriter writer = XmlWriter.Create(textWriter, settings))
{
writer.WriteStartElement(
“e”);

writer.WriteStartElement(“t1”);
writer.WriteAttributeString(
“xml”“lang”null“en-US”);
writer.WriteString(
“Hello, world!”);
writer.WriteEndElement();

writer.WriteStartElement(“t2”);
writer.WriteAttributeString(
“xml”“lang”null“es-AR”);
writer.WriteString(
“¡Hola, mundo!”);
writer.WriteEndElement();

writer.WriteEndElement();
writer.Flush();

  Trace.WriteLine(textWriter.ToString());
}

 

Here is the traced output.

<?xml version=”1.0″ encoding=”utf-16″?>
<e>
<t1 xml:lang=”en-US”>Hello, world!</t1>
<t2 xml:lang=”es-AR”>¡Hola, mundo!</t2>
</e>

 

Kerberos authentication and delegation: ServicePrincipalNames

My Hosting Blog

NOTE: while I’m still keeping the current posts live as they still seem to help, currently my focus has changed and new activity moved to the new site iternia.be

SPN’s

One of the errors that often reoccur when deploying a service is the Kerberos authentication failing for some reason when another system depends on your service. Depending users or services try to log on to your service but are not allowed to access it. This is not a problem with the enduser but with the rights of the service account on which the service itself is running. The service account doesn’t have the right to delegate access or impersonate the enduser. About 9 times out of 10 this is caused by inproper Kerberos rights due to a faulty SPN (or ServicePrincipalName) configuration and sometimes due to the delegation settings on the service account.

First lets take a look at how…
