October 5, 2012BackTrack is a security-focused Ubuntu Linux based distribution that is loaded with all the best Free Software penetration testing applications available. The latest edition is code-named Revolution, and the newest update release BackTrack 5 R3. The distro designed for penetration testers and other security professionals. Allows users to have security tools preloaded without having to worry about installing and configuring ALL the tools needed. The distro is great for anyone who wants to mess with all the best security and penetration testing applications the free software community has to offer. It is made available for public download as DVD ISO installation image and supports both 32 and 64-bit architectures. And there are installation images for KDE and the GNOME desktop environments. The distro is not really designed for your average user the system will not boot into a graphical desktop environment, but rather, into a console. You will then have to start the graphical interface. The install is exactly like the Ubuntu Desktop edition installer and I mean close in sense 99% of people would not know the difference. You can download an ISO and burn to CD or create a bootable usb jump drive either way the install itself is easy. The only issue I have read about is putting the boot partition on a separate partition. The only thing bad about the desktop is Firefox. Firefox comes pre-loaded with addons that offer additional security when you are busy surfing. So I installed chrome just to make like easy. The security tools themselves are broken into 12 categories Information gathering Vulnerability assessment Exploitation tools Privilege escalation Maintaining access Reverse engineering RFID tools Stress testing Forensics Reporting tools Services Miscellaneous Though intended for users with more knowledge of managing and navigating a Linux system the graphical management applications that you...

September 14, 2012“Originally developed by Linus Torvalds in 1991, the UNIX®-like Linux operating system now benefits from the contributions of millions of users and developers around the world. Slackware Linux provides new and experienced users alike with a fully-featured system, equipped to serve in any capacity from desktop workstation to machine-room server. Web, ftp, and email servers are ready to go out of the box, as are a wide selection of popular desktop environments. A full range of development tools, editors, and current libraries is included for users who wish to develop or compile additional software.” This statement is right off http://www.slackware.com this is one distro that really defines open source computing and the Linux distro. With one of the strongest, most knowable and helpful user base. Slackware enjoys the official position of “the eldest” of all of the currently developed distributions. Through the years, many aspects of Slackware have remained the same such as the ncurses-based installer, the use of LILO over GRUB, and the general lack of auto-configuration tools. Slackware remained true to its commitment to be the most Unix-like Linux in the market. In staying true to its great roots there are some drawn backs I found to this great OS Installation isn’t nearly as easy as most Linux distributions and there is not Live CD to try. There is no central distribution you either order a CD or download from a torrent. Slackware has no graphical package manager. It is assumed users will install everything from source and build all necessary dependencies manually. Slackware installs a lot of software. I mean a lot! Just plunge through the Applications menu and see how many tools are installed. It’s quite impressive. Slackware is no slouch with graphics KDE desktop effects working by default Lack of support the only way to ask questions...

April 14, 2012Congratulations to Linus Torvalds the creator of Linux on winning the 2012 Millennium Technology Prize this award is equivalent to winning a Nobel Prize. The Millennium Technology Prize is rewarded every two years for a technological innovation that significantly improves the quality of human life of today and in the future. I think Linus deserves it he gave away an idea that was worth billions. He is all class. His open source innovation paved the way for all the open source products of today. Making Linux open source started a whole movement into open source around the world. Linus Torvalds is a true innovator and deserves this prestigious award. Congratulations Linus you DESERVE IT!

April 2, 2012From the boot menu or the boot disk select recovery mode, which is usually the second boot option. After you select recovery mode and wait for all the boot-up processes to finish, you’ll be presented with a few options. In this case, you want the Drop to root shell prompt option so press the Down arrow to get to that option, and then press Enter to select it. The root account is the ultimate administrator and can do anything to the Ubuntu installation (including erase it), so please be careful with what commands you enter in the root terminal. Once you’re at the root shell prompt, if you have forgotten your username as well, type ls /home That’s a lowercase L, by the way, not a capital i, in ls. You should then see a list of the users on your Ubuntu installation. In this case, I’m going to reset Susan Brownmiller’s password. To reset the password, type passwd username where usernameis the username you want to reset. In this case, I want to reset Susan’s password, so I type passwd susan You’ll then be prompted for a new password. When you type the password you will get no visual response acknowledging your typing. Your password is still being accepted. Just type the password and hit Enter when you’re done. You’ll be prompted to retype the password. Do so and hit Enter again. Now the password should be reset. Type exit to return to the recovery menu. After you get back to the recovery menu, select resume normal boot, and use Ubuntu as you normally would—only this time, you actually know the password!

October 12, 2011Installing Apache 2 To only install the apache2 webserver, use any method to install apache2 It requires a restart for it to work sudo /etc/init.d/apache2 restart Checking Apache 2 installation With your web browser, go to the URI http://localhost : if you read “It works!”, which is the content of the file /var/www/index.html , this proves Apache works. Troubleshooting Apache If you get this error: apache2: Could not determine the server’s fully qualified domain name, using 127.0.0.1 for ServerName then use a text editor such as “sudo nano” at the command line or “gksudo gedit” on the desktop to create a new file, sudo nano /etc/apache2/conf.d/fqdn or gksu “gedit /etc/apache2/conf.d/fqdn” then add ServerName localhost to the file and save. This can all be done in a single command with the following: echo “ServerName localhost” | sudo tee /etc/apache2/conf.d/fqdn Virtual Hosts Apache2 has the concept of sites, which are separate configuration files that Apache2 will read. These are available in /etc/apache2/sites-available. By default, there is one site available called default this is what you will see when you browse to http://localhost or http://127.0.0.1. You can have many different site configurations available, and activate only those that you need. As an example, we want the default site to be /home/user/public_html/. To do this, we must create a new site and then enable it in Apache2. To create a new site: Copy the default website as a starting point. sudo cp /etc/apache2/sites-available/default/etc/apache2/sites-available/mysite Edit the new configuration file in a text editor “sudo nano” on the command line or “gksudo gedit“, for example: gksudo gedit /etc/apache2/sites-available/mysite Change the DocumentRoot to point to the new location. For example, /home/user/public_html/ Change the Directory directive, replace to /home/user/public_html/> You can also set separate logs for each site. To do this, change the ErrorLog and CustomLog directives. This is optional, but handy if you have many sites Save the file Now, we must deactivate the old...

November 21, 2009Here is that command for changing settings in the proc directory. sysctl -w .net.ipv4. = ie sysctl -w .net.ipv4.tcp_keepalive_time=120. This will change the value for that boot but will not be persistent across reboot.
