...Title:How to script: A Bash crash course; An easy step-by-step guide to the Bash command-line shell and shell scripting Author(s):Paul Venezia Source:InfoWorld.com. (Mar. 8, 2013): Document Type:Article Copyright : COPYRIGHT 2013 InfoWorld Media Group, Inc. http://www.infoworld.com/ Full Text: Byline: Paul Venezia Few aspects of Unix system administration are more intimate than the relationship between the admin and their chosen shell. After all, the shell is the most fundamental interface to the system, the conduit for all command-line interactions. Thus, it's important to have a solid foundation in whatever shell you choose. There are many different shells available, from Ash to Zsh. They all differ in many ways, and some (such as Csh and Tcsh) vary wildly from the others. Each has its selling points. However, because Bash has become the de-facto standard shell on most Unix-like operating systems and can generally be found everywhere, it makes an excellent place to start, even if you ultimately choose a different shell for daily use.

...“Birch” DNS Server The Mail server will be using fedora as the OS. First step will be to install fedora on the server. After successful install there are 3 packages that need to be installed. The first package will be the bind package. Next will be the bind-utils and bind-chroot packages. After successful install of all packages we will start with adding files to the chroot directory that will be implemented for security. We will do this in anticipation if anyone hacks into the server they will be confined to that directory. To do this a copy of the named.config, named.rfc1912.zones, and the named.root.hints files will made in the /var/named/chroot/etc directory.Also copy the default zone files from/user/share/doc/bind/sample/var/named into var/named/chroot/var/named directory. In the /etc/named.config file we need to add the DNS server Birch.company.com with the ip address 206.207.208.12, mail server Cedar.company.com 206.207.208.11, and web server Aspen.company.com 206.207.208.10 to the list of servers to be added to the DMZ zone.. In the /etc/resolve.config file we need to point the DNS server to quiry the ISP DNS 82.83.84.85 for unknown names or domains. This setup will allow clients on the Corp. side to query the DMZ DNS which will in turn query the ISP DNS for any name resolution and protect the internal network from being compromised. In addition to the using chroot we will also implement SELinux as addition security. To ensure DNS will run automatically at system boot...

...Linux Security Basics Security is always at the top of the list when setting up a network and also administering a network. Linux is an operating system that can be easily obtained over the internet due to its open source distributions. Linux is one of the most secure operating systems because of having less use than Windows for the end user. There are several security technologies in Linux that can be implemented into a network. The three technologies that I will be discussing are SELinux, chroot jail, and iptables. SELinux was developed by the National Security Administration in an effort to incorporate a strong, flexible mandatory access control architecture into the major subsystems of the Linux kernel. The NSA recognized that operating system security is critical at higher levels. It provides a tool to enforce the separation of information based on the confidentiality and integrity requirements. This helps when addressing threats of tampering and bypassing of application security. It also assists in the isolation of damage that is caused by malicious software or damaged applications. SELinux uses the Flux Advanced Security Kernel which contains components that provide support for enforcing many kinds of MAC policies like type enforcement, role-based access control, and multilevel security. The Linux kernel that is implementing SELinux enforces MAC policies that limit the user programs and system servers to only what they need to complete the job. When a limit...

...Diversity Walking Tour Signature Assignment Heather Zieman Brandman University May 3, 2015 Patricia Scott The area I chose to tour was an area in Rochester, MN where a lot of the people live below the poverty line. Rochester consists of about 110,000 people so there were a couple areas around town that were like this. The problems that they faced would be anywhere from windows broken, not warm enough in the winter, and the families that had children were ashamed that they lived that way. They discussed with me that they were doing the best that they could do and some even working multiple jobs just to live in the house that they live in. The first glance that one looks at the neighborhood, it looks run down with “junk” piles in some of the yards. At first glance it does not look like a good place to live but do not judge a book by the cover. The people in the neighborhood make it better because they want a better future for themselves and their children. Even if they might not be able to get out of the neighborhood, they try to make the house as beautiful as they can. They had a yard filled with flowers and decorations leading up to the door. The special part that I felt right away was that they all came together as neighbors once a week to have a “special” meal with everyone. The challenges that most of them faced would be that they did not have a car at all or one that did not work very well. It is fine to take the bus but the bus does not run 24/7 plus if one is...

...A place misunderstood The place that I will be writing about today is Idaho City because there is a lot of talk about how negative this town really is. I lived in Idaho City for about three years and I like to try to stay in touch with this particular town, even though I didn’t grow up there I still feel as it were my home. I can’t tell you how many times I have heard that all Idaho city is a place of drugs and violence and that a lot of bad, which I feel is a false statement. I think illegal things do accrue in Idaho City, but just because things happen in Idaho City doesn’t mean people should label a whole town for certain people’s actions. If you look at any town there will always be violence and drugs. I know it’s sad but it is part of the world that we live in. So I am going to argue my fact that Idaho City is a great town if you look at the things it has to offer, and not just the things that are negative about Idaho City. If you really look at it Idaho City has been around sinse1867 before I was around and will be here longer than I will live. How can we cast judgment on a town just because of some irresponsible actions of some of its citizens? I think that if you look past some of the bad things that you will see that it is a really beautiful place, and from my point of view the most beautiful place I have ever...

...Into The Wild Thoreau Quote Essay By: Kayla Hermening “I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach, and not when i came to die, discover that I had lived.” This is one of the many quotes that Chris McCandles lived by. He did exactly what the quote states. He went to live off the land and only have the essentials of life. During the summer when me and my family go Up North and stay at our cabin stranded it the middle of no where, this is exactly how I feel. While living in the society we live in today it’s really hard to get away from technology. The cabin is so far out that we barely get cell phone service and we can’t get the internet. We have cable but i much rather be outside riding the ATV than watching some stupid TV show about teens getting drunk and then knocked up. We don’t even have to use our cars when we are up north because we can drive our ATV right into town. Writers who come up with quotes have a great impact on society today. There are several things that quotes can influence, such as writers. In the song Runaway by Love and Theft, it says “and pack my bags and never look back, run a parallel line with the railroad tracks and make my getaway. This says exactly what Chris did accept Chris didn’t bring much with him when he left. “And from a rearview I got a clear view of who I used to be, a little bit faster don’t wanna turn around....

...I decided to write my project on Ubuntu, which is a distro of Linux. Ubuntu |oǒ'boǒntoō|: Ubuntu is an ancient African word meaning 'humanity to others'. It also means 'I am what I am because of who we all are'. The Ubuntu operating system brings the spirit of Ubuntu to the world of computers. (The Ubuntu Story) I chose Ubuntu because I have used it since 2009 and have loved it ever since then. I will be discussing the current distro which is 14.04, the next one will be 15.04 but 14.04 is the current stable version of Ubuntu or also often referred to as LTS or Long Term Support. The history of Ubuntu is quite short or at least 2004 kind of short. Mark Shuttleworth, from South Africa, started a company called Canonical which was created alongside Ubuntu. The purpose was to help it reach a wider market. They help governments and businesses the world over with migrations, management, and support for their Ubuntu deployments. They would work together with their partners, to ensure that Ubuntu runs reliably on every platform from the pc and the smartphone to the server and, crucially, the cloud. (Canonical) Ubuntu is part of a type of software referred to as open source, a development model promotes a universal access via a free license to a product's design or blueprint, and universal redistribution of that design or blueprint, including subsequent improvements to it by anyone. (Open source) The vision of Ubuntu is part social and part economic: free software, available to everybody...

...The world itself is full of people and the secrets hidden within. A prime example of this are from books like The Bad Seed by William March and We Have Always Lived in the Castle by Shirley Jackson. These two novels both contain characters with many secrets, many dark secrets that cause them to hide and live away from society. In a sense, these characters live in “secret worlds”. Starting off with The Bad Seed, Rhoda, the main character who is responsible for violent crimes and her mother Christine who is the “guardian angel” that’s responsible for keeping Rhoda out of trouble. Just like Rhoda, the character Merricat from We Have Always Lived in the Castle is the one causing the trouble and her sister Constance is the protector. The dark secrets of both Rhoda and Merricat involving murder provide reasons as to why they separate themselves from society, why this secrecy leads them to perversity and violence and why the emotions felt within encourage this life of secrecy. Both characters live in a world where they have a difficult time adapting to society and life problems. As a result, they do what they feel is needed even if it involves performing murderous actions. The secrecy deep within the characters lead to violence and is probably due to the fact that they don’t have the support that they need. For instance in Rhoda’s situation, her father Kenneth leaves at the beginning of the novel and heads out on a business trip. This leaves her to mainly rely on her mother Christine...

...La vaca One of the things that impact me the most when i was reading this book was describing me in some aspects of my life. I have always lived with some thoughts that have limited my life in certain way. As the book said, the mediocrity and conformism always give us the bad idea that we cannot be better than we are now. And in some cases we have to face some rude situation, like the family of the book that lost the cow, to reorganize our thoughts and ideas in order to be different and reach different goals The book said that the limitations are created by ourselves, and that is totally true, and I speak by myself. At the time I read this quote I was imagine myself nowadays in the university, the way I suffer every time that I have to make a presentation in front of my classmates, it is so hard, but now after I read this I realized that it is a vaca that I was feeding since I was a kid and I have to take the decision to kill it One aspect that I want to take into account and also to add to this great book is the felling to be less than others. It is a big cow in my life and this book showed the way how to overcome it. I always had the feeling that everyone around me is better than me at the time to speak in English, I can imagine all the words and phrases in my mind, but at the time that I have to speak and my classmates stare at me I panic and I start to think that I am not good enough to do what I have to do; I remember a lot of opportunities that I lost because of my fear...
