Linux? Which parts of the GNU/Linux operating system did each provide? Who else has helped build and refine this operating system? The Free Software Foundation (www.fsf.org) is the principal organizational sponsor of the GNU Project. GNU developed many of the tools, including the C compilers that are part of the GNU/Linux Operating Systems. Linux is the name of an operating system kernel developed by Linus Torvalds and expanded and improved What are multiuser by thousands of people on the Internet. Torvalds’s kernel and GNU’s tools work together as the GNU/Linux Operating System. 3. In what language is Linux written? What does the language have to do with the success of Linux? Linux is written in the C programming language and because it is written in the C language the language can be imbedded in all type of devices from TV’s, to PDA’s, cell phones, cable boxes for the reason of this language being so portable. 4.

Scp-secure transfer protocol is a network protocol that transfers data that can withstand or is immune to interception and tampering. 2. Use the “ssh host who” command in the terminal to show who is logged in 3. Scp user@bravo:-r your@home:blank 4. “$ ssh plum xterm” or use this command with “-y” if x11 forwarding is not trusted 5. The problem that enabling compression prevent when using a ssh to run remote x11 applications on a local display would be that this creates a backup feature. Should the computer crash, all of your work will be saved on the hard drive. 6. Check with the remote administrator to see if something has changed. Ch. 20 1.

...NT1430 Linux Networking Research Paper Nicholas Lorick ITT Technical Institute St. Petersburg Campus NT1430 Linux Networking Research Paper All people in the IT field are familiar with the IPv4 protocol and they are quickly becoming familiar with the IPv6 protocol. Bradley (2012) states the following: Since the beginning of the internet, IPv4 has been synonymous with IP and few people ever stopped to think about which version of the protocol it was. But IPv4 has outlived its usefulness. Its successor, IPv6, after nearly two decades of development is finally ready to replace IPv4 as the backbone of the Internet. (p. 34) With all the new technology and devices now accessing the internet the move to IPv6 will eventually happen. According to Bradley (2012), IPv4 is out of IP addresses. IPv4 supports only 4.3 billion addresses; and with PCs, smartphones, tablets, and gaming systems connecting to the Internet, we are running out of IP address. IPv6 uses 128-bit addresses and can maintain 340 undecillion (340 × 1036) addresses. The IPv6 protocol brings with it other benefits. With IPv4 most of the internet relies on Network Address Translation. With IPv6, every device can have its own unique public IP address. Most home and small-business users have one IP address on the Internet -- the one for the router that links their hardware to their ISP. The router issues IP addresses internally to the devices that attach to it, but it must constantly keep track of which traffic...

...Research Paper: Free and Open-Source Software NT1430 – Linux Networking Research Paper: Free and Open-Source Software As the name so aptly implies FOSS is software that is both free and open source. It is liberally licensed to grant users the right to use, copy, study, change, and improve its design through the availability of its source code. This practice is becoming increasingly widespread and gaining acceptance because of the potential benefits that could arise from its use. The “free” part of the title refers not to price, but more so to the idea of freedom for the user. The user of this type of software has the ability to copy and to reuse the software which usually is not the case. The open source part of the acronym refers to the use of the peer to peer model of development. In the 1950’s to 1970’s, advanced user privelages in reference to software were the norm. Most software allowed the user to share and copy at this time, since most of the companies who dealt in the field were more focused on marketing the hardware the software was almost always complimentary. This however, began to change when software development costs began to escalate and companies began competing for the software market. Linus Torvalds, the creator of the Linux kernel began to shift things back in 1991. His software was a freely modifiable source code. Over the years the idea gathered much more momentum. It has burgheoned so that now major IT companies are now developing projects...

...IPv6 Research Paper Current State of IPv6 DJ NT1430 Linux Networking Instructor: Mr. Brown March 5, 2013 Due to the number of limited number of internet addresses, a new internet protocol has come available to consumers, IPV6. “Internet Protocol version 6 (IPv6) is the latest revision of the Internet Protocol (IP), the communications protocol that routes traffic across the Internet. It is intended to replace IPv4, which still carries the vast majority of Internet traffic as of 2013” (IPv6, 2013). The Internet has experienced an astonishing increase of devices accessing the Internet. Because of this increase, IPv4 addresses are running out. The solution is for IPv6 to accommodate this increased demand by providing a much larger address space, along with improved traffic routing and better security. There are several advantages and disadvantages with IPv6. Some advantages are: IPv6 provides more address space, which is being needed in larger business scales, such as: Comcast. It is a more powerful internet (128bit versus IPv4's current 32 bit). It offers and overall larger scale internet, which again will be needed in the future. Address allocation is done by the device itself and support for security using (IPsec) Internet Protocol Security. IPv6 includes plug and play, which is easier for novice users to connect their machines to the network. Essentially, configuration will happen automatically. Some disadvantages are: It will be much harder to remember...

...NT1430 Final Review 1. Know what a swap partition is used for. a. The swap partition is an independent section of the hard disk used solely for swapping; no other files can reside there. Swap partition is used to turn the hard drive into extra RAM. 2. Know what an architecture is, and which are supported by Fedora. a. 32 and 64 bit b. Fedora CDs and DVDs hold programs compiled to run on a specific processor architecture (class of processors, or CPUs) c. There are several that Fedora supports: i. EM64T/AMD64 ii. A 64 bit distribution allows each process to address more than 4 gigabytes of RAM. iii. I383/i686 (Intel x86) iv. X86_64 (AMD64 and Intel EM64T) v. Mac PowerPC (PPC) 3. Know how the root of the file system is represented. a. The root is represented by a / b. 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.
