So to secure my laptop a little more I decided to implement the “something you have” method. The “something you know” method is obviously the password. Currently I [...]

One time passwords are a very effective way to connect to an SSH server from an untrusted computer. Consider the following scenario I deal with almost daily.
The computers where I take classes are owned by a governmental organization. Sounds secure, right? Not really. Quite often other students will mess with the computers as they see [...]

Around the end of October, Canonical (the company behind Ubuntu) announced the new release of Ubuntu, specifically version 9.10.

So maybe you’ve gotten tired of entering your password every time you log in to your home server. Maybe you desire better security. Or maybe you want to run automated scripts from a remote box and have their results piped to a local file. (Yay nerdiness!) Regardless this article is for you.

Just today I recalled that I was going to commit myself to posting an analysis of the spam I received each month. That was waaay back around March, so I’ve decided maybe I shouldn’t commit to that sort of time frame. What made me take so long? Well..
