HOWTO: webserver in 100 lines of Bash

September 4, 2008 – 6:48 pm

I’m a big Bash fan, I know Perl is the more popular scripting language, and I’m slowly using it more, but hey, if I need something done, I can do it quicker in Bash (keeping in mind that I’m a systems guy, not a dev guy). While at work looking up Bash related syntax I came across a page describing how to run a webserver with 100 lines of Bash. It uses the old school GNU utility Netcat (nc) for communication between the pipes, and just a ton of basic logic and functions to pass it on to the user. It’s one of those things I look at and can’t believe it works, but it does. Of course security is unknown, as is the original author, but I consider this a reference on how to do networking things in Bash; who knows what I’ll use (parts) of it for. If anyone has details on who originally wrote this I’m all ears.[sourcecode language='xml']#!/bin/bash

Use a safer browser!

July 16, 2008 – 2:20 pm
Most secure browser versions

If anything, that should be the message to all Internet surfers out there.  This graphic shows the danger, the percentage of users who have their browsers at their most secure, in regards to patches/updates being applied. Clearly people running IE aren’t going through the trouble of updating, while Firefox has updates built in that you can even automate.  Another thing to keep in mind is plugins; Firefox has millions of those, and now it takes care of keeping those updated, and disabling ones that aren’t.  So just from a software security point of view, Firefox is just a no-brainer.  The report concludes with, “Although Web browser users wish perfect software that will never have any exploitable software vulnerabilities, the nearest they can realistically hope for is that any vulnerabilities are promptly fixed by the software vendors and instantly applied to their browser. Critical to this instantaneous patching process is the mechanism of auto-update. Our measurement confirmed that Web browsers which implement an internal autoupdate patching mechanism do much better in terms of faster update adoption rates than those without.”

The importance of understanding net netrality

June 1, 2008 – 11:24 pm

To understand how importance net neutrality is you need to watch the following video.  Think about the freedom that the Internet allows you, now think about how you are limited to certain ‘packages’ when you pay for cable or satellite access to watch TV. This is exactly how the corporate behemoths want to make your choices for the Internet. It makes sense, they’re not stupid, they see the opportunity to make money, and making your freedom into the proverbial carrot and stick makes perfect sense…for them.
