There are numerous reasons you might want to inspect HTTP when debugging a problem. If you've ever tried to debug problems with sessions, cookies, or redirects, I'm sure you can appreciate how hard it is without taking a close look at what's going on behind the scenes.
In a few months we will open a new website: Windows Exposed reachable at http://www.windowsexposed.com This new Hacking and Security site will help you understand hacking techniques and numerous exploits on how they work in excruciating detail. We will show you everything you need to know about hacking and security for all major Windows versions:
Hacking XP, Hacking VISTA, Hacking Windows 2007, Hacking Windows 2003 and Hacking Windows 2008
Elcomsoft's Distributed Password Recovery (EDPR) tool that can crack WPA and WPA2 passwords faster has caused concern among users and specialists. The UK's Secure Computing magazine is quoting Global Secure Systems, a provider of security services, as saying that securing a WLAN solely with WPA or WPA2 is now no longer sufficient: additional protection with VPN encryption is necessary.
When an SEO professional tells you that he or she will secure incoming links for you, ask them to tell you specifically how they will do so. The correct answer is that they will target specific, pre-existing and established websites to gain an incoming link from them to you (in most cases without having to link back to them). If a professional tells you that they will build you hundreds or thousands of pages across different domains that will link to your website, do NOT work with them as this will severely cripple your website.
After the collapse of Napster, with places like donkax and the one and only original html suprnova, a brand new era of file sharing was upon mankind. Switch from the regular p2p networks to bittorrent seemed somewhere along the lines of changing a beat up dodge for a shiny new ferrari (blond included). Lightning fast and error free transfers of premium content, which previously took ages to receive and distribute now flowed like the precious spice throughout the filesharing galaxy. Luckily emperors were too busy to notice, while they were raping those poor few pioneers behind “napster like” p2p networks and and dump ftp “owners”, that a whole lot besides regular file sharing in its traditional sense, was going on. Spiraling out of control a brand new fully blown culture of file sharing was finding its ways into every other way of society. It was no longer something only a few chose to participate in, the event truly took a firm place, in average persons life, somewhere between the toaster and tv.
This tutorial shows you how to use netfilter to set up a powerful Linux stateful firewall. All you need is an existing Linux system that's currently using a Linux 2.4.x or 2.6.x kernel. A laptop, workstation, router or server with at a Linux 2.4.x or 2.6.x kernel will do. You should be reasonably familiar with standard network terminology like IP addresses, source and destination port numbers, TCP, UDP and ICMP, etc. By the end of the tutorial, you'll understand how Linux stateful firewalls are put together and you'll have several example configurations to use in your own projects.
Defining our goal
In this tutorial, we're going to put together a Linux stateful firewall. Our firewall is going to run on a Linux laptop, workstation, server, or router; its primary goal is to allow only certain types of network traffic to pass through. To increase security, we're going to configure the firewall to drop or reject traffic that we're not interested in, as well as traffic that could pose a security threat.
Before we start designing a firewall, we need to do two things. First, we need to make sure
that the "iptables" command is available. As root, type "iptables" and see if it exists. If it
doesn't, then we'll need to get it installed first. Here's how: head over to
http://netfilter.samba.org and grab the most recent version of iptables.tar.gz
Once installed, you should have an "iptables" command available for use, as well as the handy iptables man page ("man iptables"). Great; now all we need is to make sure that we have the necessary functionality built into the kernel. This tutorial assumes that you compile your own kernels. Head over to /usr/src/linux, and type "make menuconfig" or "make xconfig"; we're going to enable some kernel network functionality.
