Cisco Router Emulator

Joshua Wood Joshua Wood Profile: Joshua Wood

Cisco hardware and software is extremely complex. When it comes to routers their abilities are unmatched which is why a lot of people strive for the Cisco certifications of CCNA, CCNP and the highly coveted CCIE. But who can afford to purchase 5 to 10 thousand dollars for the hardware that you would need in order to practice for those exams?

Cisco router emulators will the need just perfectly. While Cisco emulators have been around for a long time their success has been somewhat limited but their stability. Recently I was re-acquanted with a very good and very stable emulator named Dynagen.

The tool highly customizable, runs on Linux and Windows, can emulate several hardware platforms and allows you to add/remove hardware as needed. Perfect for testing and training.

File Storage for the Mobile User

Joshua Wood Joshua Wood Profile: Joshua Wood

Wouldn’t it be nice if you could get to your files whether you were at home or work or while traveling.While we are at it wouldn’t it be nice if those files could be easily published to the Internet. And wouldn’t it be nice if those files were backed up and had multiple versions that you could use?

Well hopefully you won’t have to wait much longer. Drop Box is a company that will provider all of those features and more. On their home page you can see a demo of the product. From what I can tell their product will be cross-platform as well meaning Linux, Windows and Macc computers can share files over a secure connection.

The company currently has the product in beta but it surmised that they will start opening up the beta shortly.

10 Dynamic DNS Services

Joshua Wood Joshua Wood Profile: Joshua Wood

If you have an Internet Service Provider that isn’t providing you with a static IP address for some reason then it can be a really hassle to continually find out your IP address. There are a variety of reasons why you might want to connect to your home or work place such as:

    – Retriving files that are at home while you are at work
    – Running a home based web or FTP site
    – Various webcam or IP based security devices

There are services that will track your IP address and give you a nice name to refer to the IP address with. There is usually a client that you will need to install on your computer or server that will report that IP address of your home or work to the DDNS provider. The client usually small and very light weight. With the exception of a few companies the “no-frills” version is usually free.

Dynamic DNS Providers:

    – DynDNS –
    – No-IP –
    – HN –
    – ZoneEdit –
    – ChangeIP –
    – Yi –
    – DHS –
    – DtDNS –
    – DyNS –
    – DNS2GO –
