Technical Blog of an Amish Network Administrator

Category Archives: Network Administration

I’ve been asked many times by people that are getting started in the Network Administration and support what tools they need.  Many employers will supply tools that they feel are necessary for the job, sometimes what they’re giving just isn’t enough.  Some employers will not allow you to use your own tools, where others see [...]

The following is an old post in a series of posts I made about being a Network Administrator.  It’s possible the forum will be going offline in the future, so I’ve extracted many of the posts and will be placing them here for posterity.
Another day and another time to play “Stump the Salesperson”.

I know a lot of network people have different methods of setting up DNS schemes, and as far as I know there’s really no set standard for naming your devices. I try to name my devices so it’s a little easier to keep track of device names without having to resort to look up [...]

I’m currently working on a massive post about how to convert one of these little boxes into a remote Snort Sensor.

I’ve been in and out of many different networks through the years.  Many I set up from scratch, many others were set up by others.  I’ve found many times there is no rhyme or reason why the IP scheme was setup the way it was.  As a matter of fact, when I started in my [...]
