The first salon opened in 1982 and the first franchise opened in 1983 both in the state of Minnesota. In 1988, there were 150 franchises and by 2014, there are now well over 3000. Because of this tremendous growth, I have selected this company for which I will implement a network plan that will support seamless sharing and connection between various company locations. The routing protocols for IPv6 are similar to IPv4 but have been adjusted accordingly. There are two forms of routing protocols, Distance Vector routing and Link-State routing protocols. Distance Vector rules consider distance between nodes and the number of hops data must travel through before it reaches its destination. Distance Vector protocols...

...I have learned a lot of informative information in this class. From reading the book to doing the actual virtual assigned labs. The labs were very detailed which made is very interesting to work on them. Completing the class labs made the book make a lot more sense because I was able to do the actual hands on part with the labs on the virtual network. One interesting thing I learned taking this class was about the CAC card that I thought was just a very simple access card, but taking this class Dr. Powell broke it down into sections of how it works. I also worked on Linux and have a better understanding of the operating system. The Common Access Card, usually known as the CAC card, is a smart card about the size of a credit card. This card is the standard identification for United States Department of Defense (DoD) civilian employees, active-duty military personnel, Selected Reserve, and eligible contractor personnel. The CAC is designed to provide two factors of authentication; what the user has which is the physical card, and what the user and only the user themselves know which is the pin/password. It's also the principal card that’s used to enable physical access to buildings and controlled spaces, and it also provides access to defense computer systems and networks. The integrated circuit chip (ICC) which is the the little gold chip that is usually located at the bottom of the card contains information about the owner, including the PIN and one or more PKI digital certificates...

Fedora uses the Filesystem Hierarchy Standard (FHS) file system structure, which defines the names, locations, and permissions for many file types and directories. c. The two most important elements of FHS compliance are: i. Compatibility with other FHS-compliant systems ii. The ability to mount a /usr/ partition as read-only. This is especially crucial, since /usr/ contains common executables and should not be changed by users. In addition, since /usr/ is mounted as read-only, it should be mountable from the CD-ROM drive or from another machine via a read-only NFS mount. 4. Know what the cp command is used for. a. The Linux cp command is usually used to copy files and copy directory in Linux operating system. The cp command also can be used to make a link to other file in the system. 5. Know what the mv command is used for. a. The mv command is used to move files or rename to a different location or directory. 6. Know what the tail command does. a.

...NOS 120 Linux/UNIX Single User Compiling Linux Software from Source Code Objectives After reading this chapter and completing the exercises, you will be able to: * Understand basic elements of C programming * Debug C programs * Create, compile, and test C programs Text Reference: Chapter 10 – Developing UNIX/Linux Applications in C and C++ Programming Overview A computer program is a list of instructions given to a computer to make it perform a specific task or series of tasks. A programmer communicates these instructions to the computer in a language the computer understands. Computers, however, can only operate using binary code (1’s and 0’s), which makes a computer’s language very difficult for humans to understand. The solution to this problem is to create an intermediate language that both humans and computers can understand. These are called programming languages. Programmers create a list of instructions for the computer in a programming language such as C, C++, or Java. The C Programming Language The C programming language was released in 1973. C was created by Brian Kernighan, Dennis Ritchie and Ken Thompson working at Bell Labs. Both the UNIX and Linux operating systems are written in C. The C programming language is a high-level language because the code itself is written in relatively English-like statements. In 1978, Kernighan and Ritchie wrote "The C Programming Language," still one of the best C programming books available...

...SYSTEM RESEARCHED: LINUX) A common boast among Linux kernel developers is that Linux supports more devices than any other operating system in history. Indeed, device drivers account for more than half of the code in the Linux kernel. However, many devices exist that are still unsupported by Linux, and one of the best ways for a developer to get his or her code into the Linux kernel is by writing a driver for one of these. Writing a driver is also one of the most common tasks initially assigned to those hired by a company to do Linux kernel development. For these reasons, students find it particularly interesting to write a device driver as a project. Unfortunately, since our development environment involves VMs hosted on a remote server and because we are constrained to work within a ten-week quarter, it is difficult to find real devices for which students can easily write drivers. Moreover, providing devices to students might be financially infeasible, even if an appropriate device could be found. We have thus found it easiest for students to write a driver for a virtual device. Specifically, we have them implement a RAM disk driver, which allocates a large block of memory and presents it in the form of a block device ------------------------------------------------- Supported Hardware Ubuntu does not impose hardware requirements beyond the requirements of the Linux kernel and the GNU tool-sets. Therefore, any architecture or platform to which the Linux kernel, libc, gcc...

...Build Your Own Oracle RAC Cluster on Oracle Enterprise Linux and iSCSI (Continued) The information in this guide is not validated by Oracle, is not supported by Oracle, and should only be used at your own risk; it is for educational purposes only. 12. Create "oracle" User and Directories Perform the following tasks on both Oracle RAC nodes in the cluster! In this section we will create the oracle UNIX user account, recommended O/S groups, and all required directories. The following O/S groups will be created: Description | Oracle Privilege | Oracle Group Name | UNIX Group name | Oracle Inventory and Software Owner | | | oinstall | Database Administrator | SYSDBA | OSDBA | dba | Database Operator | SYSOPER | OSOPER | oper | We will be using the Oracle Cluster File System, Release 2 (OCFS2) to store the files required to be shared for the Oracle Clusterware software. When using OCFS2, the UID of the UNIX user " oracle" and GID of the UNIX group " oinstall" must be the same on both of the Oracle RAC nodes in the cluster. If either the UID or GID are different, the files on the OCFS2 file system will show up as "unowned" or may even be owned by a different user. For this article, I will use 501 for the " oracle" UID and 501 for the " oinstall" GID. Note that members of the UNIX group oinstall are considered the "owners" of the Oracle software. Members of the dba group can administer Oracle databases, for example starting up and shutting down databases. Members...

...Terrez Ellis 68745 February 2, 2011 A+ Computer Operating Systems Crt 1101 Physical Security Physical Security The first layer of security you need to take into account is the physical security of your computer systems. Who has direct physical access to your machine? Should they? Can you protect your machine from their tampering? Should you? How much physical security you need on your system is very dependent on your situation, and/or budget. If you are a home user, you probably don't need a lot (although you might need to protect your machine from tampering by children or annoying relatives). If you are in a lab, you need considerably more, but users will still need to be able to get work done on the machines. Many of the following sections will help out. If you are in an office, you may or may not need to secure your machine off-hours or while you are away. At some companies, leaving your console unsecured is a termination offense. Obvious physical security methods such as locks on doors, cables, locked cabinets, and video surveillance are all good ideas, but beyond the scope of this document. :) Computer locks Many modern PC cases include a "locking" feature. Usually this will be a socket on the front of the case that allows you to turn an included key to a locked or unlocked position. Case locks can help prevent someone from stealing your PC, or opening up the case and directly manipulating/stealing your hardware. They can also sometimes prevent someone from...

...IT 302 LINUX ADMIN PROJECT I chose to do my final project on the Samba server, such as how to set up the server, security, and maintenance. Samba “is an Open Source/Free Software suite that provides seamless file and print services to SMB/CIFS clients. Samba is freely available, unlike other SMB/CIFS implementations, and allows for interoperability between Linux/Unix servers and Windows-based clients.” (source1) The whole purpose of the samba software is to make it possible to operate on many platforms. To install the server you would use the yum command in terminal. You then would enter su for the “super user” to install files as root. Then create a new directory containing three empty files which you'll share. While logged on as root create the new directory “/smbdemo” using this command “mkdir /smbdemo”. Then you would change permissions on the new directory to 770 with the following command “chmod 770 /smbdemo”. Now you navigate to the new directory with “cd /smbdemo” for the command. Add three empty files to the directory with the following command “touch file1 file2 file3”. Next step one would most likely add a user to the server. You do this first by “adding users to the Samba database in order for them to have access to their home directory and other Samba shares.”(source2) Using this command “smbpasswd -a ” you will then be able to add a new samba user. The user must be an existing Linux user or else the command will fail. Then if you “perform the following...
