So hopefully, I can collect this information in a simple and coherent manner so that it may prove helpful to those of you that have stumbled upon this blog.Anonymoushttp://www.blogger.com/profile/12918881880845831345noreply@blogger.comBlogger11125tag:blogger.com,1999:blog-8734158614848842338.post-5656322453460077052010-10-21T17:29:00.001-04:002010-10-21T17:29:16.770-04:00

ProtectmyID had a good writeup on WLAN security today. I think this is one of the writeups on this topic which contains the least amount of FUD and you can't go wrong with following its advice. However, I think a couple of improvements could be made.First off I'd say that MAC filters these days are a waste of time as a MAC address can be easily spoofed. The time required to manage a MAC filter

I was just looking at the securing coding practices at the CERT website and ran into a topic that has always been a pain point for me and that is the validation of pointers in C. Growing up coding C, I was constantly exposed to the mantra of 'Check for NULL pointers'. Now it is hard to argue that NULL pointers are not bad, but I do think that when to check for them is not that straight forward.

I recently received one of Microsoft's periodic download notification emails and one item in particular caught my eye as I had never heard of it before. It was a download of Microsoft's Network Monitor. Now I've been dealing with networking in and out of work for many years and have always used Wireshark and will most likely continue to do so.  However, I will definitely be looking into

If you are dealing with issues with networking on a Windows machine one of the locations you are going to want to look at sooner or later is the Network Connections.  How you get there and what you see varies between Windows versions. From XP on it is mostly the same, so I figured a quick look at Network Connections on XP should provide most Windows users with a good starting point if they

I've been working on a few different posts and haven't quite got the finishing touches on them, but I felt I should get this one out there.  In the past week, I have been asked to help out with expanding a home network using an old router at least four times.  With many ISPs providing routers, people are often finding themselves with an extra router.   So its only natural that

 In a couple of my previous posts I've covered running various commands from  a command window like the one shown to the left.  Now while the command window is a simple application, which provides a way to run other applications or Windows commands, how to do some simple things in it  is not always clear. For example I have run into many situations where someone does not know

 You've most likely heard of KVM (Keyboard/Video/Mouse) devices that let you share a single keyboard, monitor, and mouse between multiple machines, Synergy is a software KM solution.   It allows you to share a keyboard and mouse between multiple computers, but still take advantage of having the display real-estate that multiple monitors offer.  Since it runs on Windows,

The first questions that I imagine comes to the mind of many people is what is MTU and why should I care about it. I expect a more or less formal definition is not that useful when it comes to answering these questions. Maximum Transmission Unit [MTU] The largest possible unit of data that can be sent on a particular network implementation The MTU can be thought of the largest amount of

The ping command is one of the simplest commands that can be used for diagnosing networking problems, but it is also one I would be hard pressed to do without.  The primary use of the command is to send a network message to another system asking that system to respond back.  By doing this you can easily verify that the remote system can be reached from your system and get a gauge of the

Over the past couple of years I've been pulling together a list of terms that frequently get tossed about when dealing with networking issues and trying to provide a definition that is easy for most folks to follow.  This list is by no means exhaustive and was meant all along to be a living document, growing and being revised as time goes by. You can find this glossary of terms over in the

In Windows, ipconfig is used to display basic network related configuration information, such as IP address, DNS servers, and DHCP settings.  It is a command line utility and as such it must  be run through XP's command window.  There are two basic ways to do this: Either, 1)  Go to the Start menu and select Run...      In the the Run dialog enter cmd /k
