Android App Build Environment Setup With Eclipse, PhoneGap (Ubuntu 11.04)

Post date: June 28, 2011, 11:06 Category: Installing Views: 3360 Comments
Tutorial quote: This tutorial describes how you can set up an development environment for building Android apps on an Ubuntu 11.04 desktop using Eclipse, the Android SDK, and PhoneGap. I will describe how to build Android apps from the command line with PhoneGap and from the GUI with Eclipse and PhoneGap and how to test them in an Android emulator and on a real Android device. PhoneGap allows you to develop your Android applications using web technologies such as HTML, CSS, and JavaScript (e.g. with JavaScript libraries such as jQuery/jQTouch), and it will turn these web apps into native Android apps (in fact, PhoneGap supports multiple platforms such as Android, iPhone, Palm, Windows Mobile, Symbian, so you can use the same sources to create apps for multiple platforms).

Three tools to help you configure iptables

Post date: May 25, 2005, 14:05 Category: Network Views: 3837 Comments
Tutorial quote: Every user whose client connects to the Internet should configure his firewall immediately after installation. Some Linux distributions include firewall configuration as a part of installation, often offering a set of defaults configurations to choose from. However, to ensure that your machine presents the minimum "attack surface" (a measure of the number of vulnerable ports, user accounts, and sockets exposed to attack) to the predatory inhabitants of the Internet, you may need to do some manual configuration of your firewall. Here are three tools that can help.
The Linux kernel (version 2.4 onwards) contains a framework for packet filtering and firewalling using netfilter and iptables. Netfilter is a set of hooks inside the Linux kernel that allows kernel modules to register callback functions with the network stack. Iptables is a generic table structure for the definition of rulesets. Each rule within an IP table consists of a number of classifiers (iptables matches) and one connected action (iptables target). Iptables has extensive documentation that can be accessed online or by typing man iptables at the command line. Yet despite the depth of the documentation available for iptables, its complexity can be baffling.

Firewalling with OpenBSD's PF packet filter

Post date: April 19, 2005, 02:04 Category: Network Views: 7927 Comments
Tutorial quote: PF operates in a world which consists of packets, protocols, connections and ports.

Based on where a packet is coming from or where it's going, which protocol, connection of port it is designated for, PF is able to determine where to lead the packet, or decide if it is to be let through at all.

It's equally possible to direct network traffic based on packet contents, usually referred to as application level filtering, but this is not the kind of thing PF does. We will come back later to some cases where PF will hand off these kinds of tasks to other software, but first let us deal with some basics.

We've already mentioned the firewall concept. One important feature of PF and similar software, perhaps the most important feature, is that it is able to identify and block traffic which is you do not want to let into your local network or let out to the world outside. At some point the term 'firewall' was coined.
