The regular install on a Raspberry Pi is NOOBS (new out-of-box software) and contains several pre-packaged operating systems. However for the purpose of our MITM device we’ll be using a different Linux distro for our Pi: PwnPi. PwnPi is a distribution of the Raspbian OS that contains many pre-installed packages for security and penetration testing which is naturally right up our alley. So, go ahead and download PwnPi. Once it’s downloaded we’ll need to load it onto our SD card. First, format your SD card using the SD card formatter from the SD association. If the “size” value shown in the formatter is less than the size of your card, be sure to choose “format size adjustment” in the card.
If the idea of a networked security camera that you can remotely view and receive alerts from appeals to you but the $$$ of a commercial model does not, read on as we show you how to turn older generation Android phones into sophisticated security cameras.
You’ve written some code, you think it would be useful to the world, and you’d like to give back to the open source world. But how do you do it? An experienced open-source guy provides a checksheet for developers to release an open source project and get it noticed.
You can send visitors to different servers based on country of their IP address using Amazon Route 53 cloud based dns server. For example, if you have a server in Amsterdam, a server in America, and a server in Singapore, then you can easily route traffic for visitors in Europe to the Amsterdam server, people in Asia go to the Singapore server and those in the rest of the world be served by the American server.
In this post, I will explain how to configure and test GeoDNS using AWS Route 53 service.
There are various captive portal software packages available (both free and open source) that will allow you to setup an internet access facility that people have to logon to first. None of the packages I tried did what I wanted and they were not particularly customisable. Therefore I created my own, using a few iptables rules and PHP (along with a handful of other standard packages). This page details the steps that were taken. The key to this method as opposed to other iptables based solutions is that tracking information is removed after the user has signed up. Failure to do this will sometimes cause the user to still be redirected to your logon page even after they have signed up.
Captive portals allow for a splash screen to be delivered to a user upon entering an open network such as free wifi hotspots at various establishments. This portal typically shows terms of service and displays some branding. The user hits OK and then they’re free to use the network. I find this burdensome but in the world of branding and advertising I can understand why places may want this. I found the above iptables only solution with some PHP interesting. Here’s another site.
For Squid users it appears to be even easier by only requiring some configuration changes. See Portal Splash Pages for more information.
Android tablets don’t have an automatic method or desktop management software to sync your files from the device to a personal computer. However, there is a way to do it manually, a process which requires mounting the device so the computer recognizes its file system, then moving pictures, videos and other data to the computer’s local hard drive.
This entire site seems like a good reference on many topics relaing to using tablets based on android.
Configure Linux to Work with Skype
I’ll assume that because you’re a Linux Journal reader, getting Fedora Core 3 up and running on your Skype server is a no-brainer. The only important thing to remember is that Skype is a Qt application (though it’s also available in a version with Qt statically linked), and the Skype API uses D-BUS. Also, disable the screensaver (after all, there won’t be any screen to “save”) and power standby features as these may interfere with Skype.
Here’s a step-by-step guide to setting up Linux to work with Skype (it assumes you have set up a Linux user account named skype for the purpose):
This guide shows the basic requirements and steps to build a WISP (Wireless Internet Service Provider) using Ubiquiti AirMax devices; suggested equipments and examples are intended for a system of up to 400 subscribers based on a single Base Station and “centrally managed” from the principal router. It covers the following themes: basic legal and commercial requirements, required equipments and basic services on the Base Station, clients’ configuration and general recommendations for starters.
You can setup a wireless connection between two routers only so that it will link a wireless network to a wired network allowing you to bridge two networks with different infrastructure. You can find wireless access points products that offer either a “bridge” mode or a “repeater” mode. In this post I’m going to explain three popular open source choices that can be used for setting up a wireless bridge.
