Systems Administration And Network Services

Systems Administration And Network Services
1.Goal After two labs focusing purely on the Linux side of systems administration and network services, this third lab puts Windows into the spotlight
and how it deals with configuring services as compared to the previous RHEL–based configurations. Many of the same tasks which were completed
using a RHEL 7 virtual machine in lab 2, such as setting up DHCP and DNS, are repeated in this lab on a Windows 2012 Datacenter virtual
machine. This is done not only to show the differences in service administration, but also to indirectly teach students the steps as well as
precautions that need to be taken when integrating in different enterprise server operating system families which very well could be running the
same network services, such as in the case of this lab. Instead of merely just installing the same services and letting the clients make decisions on
what data to receive from who, this lab also presents the challenge of making these two very different operating systems work together when the
time comes to configure the DNS server on the Windows VM. A major point I took away from this is that while the Microsoft and ISC
implementation of a DNS server can be seen as widely different, the integration of the two is very smooth and easy due to both of them still
following the base rules of the DNS protocol as well as framework found in the numerous RFC's which describe it. Active Directory, which is also
installed on the server, was review at this point from multiple different

MS Windows vs. Unix/Linux
The Microsoft and Linux operating systems have been long considered to be in a competition to be the best operating systems on the market. This
paper will compare and contrast these operating systems to help the consumer decide which is right for his or her environment. Such subjects as; cost,
market share, hardware requirements, file processing, programming capabilities, availability if application software, networking, and user interface will
be examined.
Cost
The cost difference between running a Linux desktop / server compared to a Microsoft desktop / server is overwhelming. ... Show more content on
Helpwriting.net ...
Finally, marketing is a big "reason" why Microsoft still holds a large place in the desktop market share. Microsoft is constantly keeping their
products in the public eye view, where Linux does not, causing people to know of Microsoft desktops but not so much about Linux desktops. With
that said, while Microsoft does hold a dominate place in the desktop world, the same is not so true in the server world.
In the server marketplace, Microsoft is losing ground quickly to the Linux Server. Linux has been gaining ground in the server world for several
reasons including; cost, ease of use, and dependability. The cost of the Linux server is much lower than that of the Microsoft server as we examined

earlier. This cost difference is opening up IT departments to the ideal of using Linux over Microsoft, which in return is helping Linux gain server
market share. Next, because Linux is becoming easier to administrate, that too is moving IT departments to convert. In the past, Linux was all
"command prompt" oriented, today GUIs and such have been developed to help the novice user with system administration. Finally, dependability is
probably the biggest reason Linux is gaining server market share. Perhaps the best way to explain Linux dependability is to explain that Linux does
not need to be rebooted once a week. But in

This necessitates the need for an ideal web server platform choice. Several operating system (OS) platform alternatives are available to Tony's Chips.
For instance, the company can choose to run the new system on a Microsoft Windows Server OS platform. Some of the server platform applications
provided by Microsoft include Windows Server 2008 and 2012. These operating systems are advantageous in that most online applications are
available to the Microsoft Windows Server platform. Additionally, expertise on Windows server OS is readily available. As a result, implementation
and maintenance operations for applications using this platform are complemented by available personnel. However, Microsoft's licensing fees for
new versions of the OS present an economic obstacle to the adoption of the platform. In addition, the platform's security facilities are not as reliable
as those of alternative server platforms such as Linux and UNIX (MacDonald, 2009). Linux offers a variety of server OS distributions. These include
Red Hat, Ubuntu and CentOS. These server platforms have the common advantage of being easily customizable, stable, secure and robust (Tanenbaum,
2001). Cento possesses the best expertise support among Linux distros. This is because of its long development cycle. CentOS, however, does not
possess the enterprise level operating abilities of Red Hat Linux. Of the currently available Linux distributions, Red Hat

Abstract
There are a number of operating systems available for personal use as well as small and large businesses. Probably the two most popular are Linux
and Windows. In order to determine what operating system best suits your needs, it's important to know some background on Linux and Windows.
Some important factors to consider in the selection of an operating system are what are some of the things that make Linux and Windows appealing
and what are some of their drawbacks. In today's economic conditions, it's vital for companies to try and keep costs down. This paper will also look
at the cost of each operating system. Based on all of these factors, one of the operating systems is recommended ... Show more content on

Using either GNOME or KDE, you can decide what interface you want and then add only the features that fit your needs quickly and easily. If you are
concerned with standardization, do not worry. Linux sticks to the Unix standards. The Institute of Electrical and Electronics Engineers put together the
American National Standards Institute for Unix named the Portable Operating System Interface for Computer Environments. It dictates a universal
standard on how the Unix–based systems are supposed to operate. (Asprey & Seruzzi, 2008) Linux has three major components–the file structure,
kernel, and environment. The file structure does what its name implies, puts files in a specific order on any storage device. They are arranged in a
hierarchy of directories and one or more subdirectories all of which contain files. These directories are all interconnected. With the exception of the
standard directories that are set aside for system use, users have full control of the files inside the directories. They can create and move directories,
move files between directories, share or restrict directories and files just by setting directory and file permissions. (Asprey & Seruzzi, 2008) The
kernel is really the heart of Linux. Its job is to operate all the programs and manage the attached hardware devices. In order to put these kernels to work
and operate any computer operating system,

Microsoft Baseline Security Analyzer And Windows Server 2012
1. Goal The main idea behind this lab was to relocate the DHCP server and master DNS server to a fresh install of Windows Server 2012. This
would allow control over most of the network with Windows Server 2012 while maintaining a slave DNS server on the Red Hat Enterprise Linux 7
box. A basic install of Active Directory was also implemented, allowing a single client to connect to the bestnet.local domain. Microsoft Baseline
Security Analyzer was also implemented to determine any outlying security risks associated with the WindowsServer 2012. This lab took the
knowledge that I gained from in–class lectures and previous experiences, and allowed me to implement Active Directory, DHCP, and DNS flawlessly
on Windows Server 2012. It helped me to understand how Active Directory and DNS are linked together to tie a domain together and populate that
domain. By playing around in Active Directory, I was able to gain valuable knowledge of how to implement many features and roles directly related to
an Active Directory installation.
2. Procedural and Informational Documentation All information pertaining to my virtual network can be found at the address http://10.0.15.1/wiki or
http://wiki.bestnet.local/wiki/ when inside my infrastructure. It contains all the information needed to understand how I built and configured my
virtual machines, and how I installed and configured each of my servers. It is broken up by specific Operating System installs, so there is are sections for

Windows Server Business Plan
I propose that our company consider implementing Linux for our servers and workstations. There are many excellent reasons to employ Linux as
the operating system of choice for our company: Linux is 'tried and true'; is used by many large companies, such as Google©, Amazon©,
Facebook©, and many of the cloud service providers; is less expensive; more reliable and stable; has extensive free community support; uses memory
and CPU resources more efficiently; is reasonably easy and quick to install; and is much less vulnerable to viruses and malware than the Microsoft
Windows© operating system. Linux can be used on almost any type or brand of computer or server, including older models. I will demonstrate that
Linux is a viable and less expensive alternative to Windows and will perform well in our server and workstation environments.
Server Environment
Hardware Considerations
Existing hardware. Our existing hardware can be used for the new Linux OS. This will require reformatting existing hard drives and installing the
Linux OS, which is much easier than reformatting and installing Windows OS. Our older servers will still be viable for some time to come because
Linux uses less disk space and memory. It also uses less resources, so it won't slow down the devices or the network like other Enterprise OS can.
Vendor specific hardware. If we wish to purchase vendor–specific hardware for one of the new Linux distributions, there are several options:

Linux Based Systems Are Modular Unix Like Oss Build A...
Linux based systems are modular Unix–like OSs build a large part of its component from 1970s and 1980s UNIX principles. They apply a monolithic
kernel, commonly identified as the Linux kernel to execute process control, access to peripherals, file system management and networking tasks. Lonix
OS drivers are either directly integrated with the kernel or come in as additional modules created while the system is awake. Independent developments
with kernel interface improve the functionality and performance. GNU user land association with Linux based systems provides majority executions in
the C library, a command–line interface (CLI) shell and the most common tools of UNIX to carry out performance execution. A GUI is created on
each implementation of the X windows system. A recent development of the Linux OS is the use to Wayland display server protocol replacing the
X11. Ubuntu has made progressive developments of the Mir a diversion of Wayland.

The Linux system main components comprise of
i.Boot loader– this is a program build to load the Linux kernel and input it in the computers main memory. It starts its operations when the machine is
switched on and after firmware initialization execution. GNU GRUB, LILO, Coreboot, Gummiboot, and GNU GRUB are some common boot
loaders. ii. An init program: this is the very first operation initiated by the kernel and serves as the background of the process. An init program causes
the device to initiate any process running processes

Microsoft's internet information services (IIS) is one such solution. This webs server is designed to run on Windows server platforms. Consequently, it
integrates well with Microsoft's online applications. It features an intuitive graphical user interface that simplifies its installation and use. However, the
costs of installing new versions of this web server are high. In addition, its restriction to the Microsoft server OS platform inhibits system flexibility.
An alternative to IIS is the Apache web server. This is an open sourced application that can be implemented on a wide variety of operating system
platforms. Apache's integration of a pearl and PHP engine facilitates easy integration with the application programming interface (Gunther, 2006). In
addition, this web server is available for free. This makes it a cost effective alternative. Further, Apache's event–driven architecture enables it to perform
ideally even under heavy loads. However, Apache usage involves a relatively strenuous learning curve. The software's complexity may present an
obstacle to its use by new users. Another web server that can be adopted for use in this project is Nginx. This server is easy to use as well as stable.
It is also based on an event driven architecture. This architecture makes it an efficient user of system resources even under heavy loads (Tanenbaum,
2001). Nginx's ease of installation, configuration, and use make it a viable alternative for adoption in

Linux Operating System (graduate level CIS term paper)
1. What Is Linux?
Linux is an operating system that was initially created as a hobby by a young student, Linus Torvalds, at the University of Helsinki in Finland. Linus
had an interest in Minix, a small UNIX system, and decided to develop a system that exceeded the Minix standards. He began his work in 1991 when
he released version 0.02 and worked steadily until 1994 when version 1.0 of the Linux Kernel was released. The current full–featured version is 2.4
(released January 2001) and development continues.
Linux is developed under the GNU General Public License and its source code is freely available to everyone. This however, doesn't mean that Linux

Process management creates processes, and implements multitasking by switching the active process on the processor.
At the lowest level, the kernel contains a hardware device driver for each kind of hardware it supports. Since the world is full of different kinds of
hardware, the number of hardware device drivers is large. There are often many otherwise similar pieces of hardware that differ in how they are
controlled by software. The similarities make it possible to have general classes of drivers that support similar operations; each member of the class
has the same interface to the rest of the kernel but differs in what it needs to do to implement them. For example, all disk drivers look alike to the
rest of the kernel, i.e., they all have operations like `initialize the drive', `read sector N', and `write sector N'.
Some software services provided by the kernel itself have similar properties, and can therefore be abstracted into classes. For example, the various
network protocols have been abstracted into one programming interface, the BSD socket library. Another example is the virtual filesystem (VFS) layer
that abstracts the filesystem operations away from their implementation. Each filesystem type provides an implementation of each filesystem operation.
When some entity tries to use a filesystem, the request goes via the VFS, which routes the request to the proper filesystem driver.

Sid is a villainous character; he destroys toys for fun and is feared by all of the toys. Woody shows his great leadership again when he organizes the
toys in a revolt against Sid, leaving him shaken and very scared. He is a very dark character and this is shown by his image, a black t–shirt with a skull

I have a great understanding in operating and troubleshooting the Windows OS. The internet systems admin requires knowledge in the Linux OS. I am
very familiar with installing Linux and the basic functions of it, but I am not comfortable with saying I know how to troubleshoot and work heavily
with a Linux OS. More specifically the position requires knowledge in two distributions of Linux, I'm only familiar with the basic Red Hat
distribution, but I know of several other types. Understanding and operating Linux is important in IT especially in the Networking and web fields as
a majority of those systems are run with Linux. Web servers and host a majorly run with Linux. Linux is vital to understand as there is note many
people knowledgeable in it, however, it is a very challenging system to learn and something I need to practice at.
Expanding upon Linux, I have a strong desire to learn it. While at my internship at Harris, one of the people with whom I worked closely with was a
master of Linux. It is a very intriguing operating system that is highly flexible. It has the highest security as its code is unique because it is open
source, which allows for it to be programmed into any system. I have seen Linux based software used to hack into a computer, duplicate hard drives,
and emulate systems.

1.Find and report all files with peculiar permissions. Examples: no permissions given ––– ––– –––, executable but not readable, readable for group and
others but not the owner, unsearchable directories, etc.
To view file permissions, I used ls –la (–– removed HTML ––) command. For instance, to display all the files of the /root directory, I typed ls –la /root.
(see figure 4). The –a option would display the hidden files which are typically the system files. Figure 4: viewing file permissions
The log.txt has no read, write, execute permissions.
2.Files and directories whose names begin with a dot are unlisted by ls unless –a flag is used. Find and report all such files and directories whose size

1.No password shoul be breakable within an hour. List the names and plain text passwords of such users. Assume you are root.
2.Should root be allowed to login? Ubuntu/ Debian do not assign a passwd to root. Discuss the pro/cons of this choice.
The advantages of not having root password is that the users can easily swich to root without signing in with a password. This gives a flexibility of

Linux versus Windows XP: The Pros and Cons
This may be the perfect time to move over to Linux, since Windows XP was officially retired in 2014. Although we can continue using Windows XP,
the two most important factors to consider are 1) there will no longer be security patches released by Microsoft; and 2) they are no longer supporting
this product.
Additionally, our older XP machines may not support newer Windows releases, especially 8.1, because it needs significantly more power and
storage. Also, some XP applications may not work on newer versions of Windows. So to run 8.1 on older PCs, there will be a lot of configuring to do
which takes time and money. All machines will need at least 4 GB of ram.
That said, both Windows XP and Linux each have their advantages and disadvantages. To help determine what technology option is best in the long
run for the company (i.e., to keep Windows XP or switch to Linux), the team recommends that you perform a careful analysis with respect to cost,
performance and risk to make the right technology decision. We don't envy your position–which is challenging–one that can affect the company 's total
cost of ownership (TCO) and return–on–investment (ROI), positively or negatively.

Windows XP will continue to work, security is a major concern. Although security companies still support XP, at some point we could find ourselves
vulnerable. Without security patches, cyber criminals will have more opportunities to

New Research And Development Group
The new research and development group, LSDG, of HACKD, LLC, will be migrating all Windows XP machines to a Red Hat Enterprise 5 Linux
distribution to optimize performance and user capability. As described perfectly by Karen Schwartz there are many reasons to switch "The reasons
are compelling: greater stability and reliability, lower cost, access to application source code, greater security, and conformity with open standards"
(Schwartz, 2004). The LSDG group will access and share resources with HACKD, LLC.'s Active Directory domain such as authentication, DNS,
DHCP and file services to save on expenses and reduce the required footprint and administrative overhead.
Hardware Requirements
The current Windows XP machines within HACKD LLC. have the following hardware specifications: Intel Core 2 processor, 2GB RAM memory,
80GB hard drive, 10/100 Mbps network cards, 4 USB 2.0 USB ports, and 15 inch LCD monitors. In order to support the migration to a Red Hat Linux

The Pros And Cons Of Linux
In the beginning, Linus Torvalds, a young man who studied computer science at the University of Helsinki, thought Unix–like academic operating
system should be available for free and is an open source software.
Hence, he decided to do a better operating system which is free of charge and is an open–source software. The Linux kernel was first released in 1991,
it is designed to be used with GNU software. GNU developers eventually integrated their software into Linux to create an operating system. Linux is
everywhere so it is available in many forms to suit many needs where from consumer– oriented systems for home use to distributions for use in specific
industries. For instance, it is in our smartphone, our Roku devices and even in our refrigerator. ... Show more content on Helpwriting.net ...
Linux is a software on a computer that enables applications and the computer operator to access any devices on the computer to perform its desired
functions. To put it simply, Linux is an operating system that enable to manage the communication between software and hardware. The operating
system (OS) relays instructions from an application to, for example, the computer's processor. The processor performs the instructed task, then send the
results back to the application via the OS.
As we know, Linux is all free and easy to install. This zero cost of entry accompanied with an open source license. Open source follows the following
key of philosophies, for instance, the freedom to study how the program works, the freedom of running a program, the freedom to redistribute copies
and also the freedom to distribute copies of the modified versions to the others.
Linux is said everywhere because it is powering roughly 94% of worldwide supercomputers, most of the servers powering the Internet, the majority
financial trades worldwide and a great number of Android devices. It also appears in many different architectures, from mainframes to server to
desktop to mobile and on a wide variety of

Iphone Xp : A New Research And Development Group Essay
Introduction My boss asked me to come up with a proposal to migrate Windows XP machines to Linux. The company Linx LLC has a new research
and development group – LSDG. All systems in LSDG will be running Linux and will access and share resources with Linx LLC. The company has
around 500 client operating system desktop/laptops that runs Windows 7 and Windows XP. LSDG needs to decide whether they're going to keep using
both Windows XP and Windows 7 on their desktops and laptops. LSDG must consider the following: costs, longevity of the machines, security, and
support. If LSDG decides to keep using Windows XP as their operating system, the company will end up spending more to maintain and configure
those machines. I would propose for Linx LLC to have all their machines running Windows XP to update to Red Hate Enterprise Linux Operating
System. The last time for Windows XP support was back in 2014. "After 12 years, support for Windows XP ended April 8, 2014. There will be no
more security updates or technical support for the Windows XP operating system." ("Support for Windows," n.d.) Running only Windows 7 variant
on some the machines makes it easier to have updates and especially security patches as well as technical support when needed. Running Windows
XP is a major security risk because like I said Windows already stopped supplying patches and updates for this variant. As I suggested, Red Hat
Enterprise Linux Operating System will be the best choice to be used by LSDG. The

Windows Active Directory is a central hub where a system administrator can change anything about a users role in the organization and access on
the network in a very short time unlike Linux. Because SELinux is host based that means each change to a user or group means going in and
configuring them one at a time by hand while Active Directory GUI is much simpler to use when configuring. Another benefit to active directory is
the ability to authenticate. Authenticating prevents a user without the proper rights to access something that they don't nee to edit or view. Once
authenticated a user has access to all internal Microsoft services and features that the policy allows for. I feel that SELinux and OpenLdap if better
for network management in the sense that it is very flexible and can better manage the network. The only downside to this is it is much harder to set
up and configure. OpenLdap also has issues working with and connecting to windows devices on the network. It is very rare in an organization to
only see Linux with no Microsoft servers or clients. Even though OpenLdap has the potential to be better at managing because of its flexibility a

Since Linux is allowed to be changed by its users there are more than 600 distributions available. Here is a list of five of the most commonly used.
FEDORA– fedoraproject.org (2013) states, "fedora is fast, stable, and powerful operating system for everyday use built by a worldwide community."
This distribution is most commonly used by developers and Linux enthusiast.
DEBIAN– debian.org (2013) states, "Debian provides more than a pure OS: it comes with over 37,500 packages, pre compiled software bundled up
in a nice format for easy installation on your machine." It is one of the oldest distributions still in active development, and is often the base for newer
distributions. People that have a passion for Linux enjoy Debian. openSUSE– according to opensuse.org (2013), " The openSUSE distribution is a
stable, way to use and complete multi–purpose distribution.it is aimed towards users and developers working on desktop or server." This distribution
is generally used in an enterprise environment, and is sponsored by Novell. It is known for its ease of use on the surface and advanced options further in.

The issue is that in Windows, icons are executed from modules (either executables or dynamic link–libraries). In fact, .CPL files are actually DLLs.
Because an attacker could define which executable module would be loaded, an attacker could use the .LNK file to execute arbitrary code inside of
the Windows shell and do anything the current user could" [2]. The first patch released August in 2010, Microsoft put in an explicit whitelist check
with MS10–046. Once installed, it intended to ensure that only approved .CPL files should have been used to load non–standard icons for links. This
patch failed and for more than four years, all windows files have been vulnerable to exactly the same attack that stuxnet attackers used in initial
exploit. In light of its recent rediscovery, it is unknown if other groups discovered and exploited the vulnerability in the wild [2]. The section below

Generally, computer components are two–fold, namely hardware and software components. The hardware requires an operating system (OS) to
manage and coordinate its software resources as well as provide services for computer application programs [4]. Application programs that run in a
computer require an OS. In essense, the OS acts as a central host that handles hardware operation details [4]. All computers are run by an OS of some
type. Some of the most popular OS versions in the market are Linux, Windows and FreeBSD [1]. Linux is an open–source development and free
software whose source code can be freely used, redistributed and modified by third party OS developers. The range of Windows Operating Systems are
created by Microsoft Corporation. Unlike Linux, Windows consists of proprietary closed sources [5]. FreeBSD is an advanced version of OS and runs

Administration
Riordan Manufacturing Corporation, (Apollo Group, 2004), is a hybrid computing environment employing MS Windows, (Microsoft Corporation,
2011), e–mail and file servers along–side UNIX Enterprise Resource Program (ERP) and a HP–UX, (Hewlett Packard Development Company, 2011),
UNIX Manufacturing Resource Program (MRP). Effective administrative support of both operating systems requires two information technology
groups, one specializing in MS Windows platforms and one specializing in UNIX platforms. Requiring two IT groups and two unique server platforms
doubles the administrative management and equipment costs in the enterprise. Standardizing server hardware and software to one type will
significantly reduce costs and increase Riordan Manufacturing's return on its investment. One server operating system platform can support all of the
workstation's applications with the exception of MS Windows Exchange, (Microsoft Corporation, 2011), e–mail application.
To reduce personnel costs it is recommend merging the two server platforms (operating systems) to one where it is possible. HP–UX,

In windows almost every file require the use of extension in order for the system to function.
In Linux operating system they do not require the use of extension.
In Linux, the extensions are used only to make the user understand the type of file.
TYPE OF FILE: o In windows: hello.mp3 will be a mp3 file only and the extension is important to be specified. o In Linux: hello.mp3 is considered as
a normal file which can be used for texts, video etc
