...Red Hat Linux Virtualization for Desktops By: Dorein Pfeil Instructor: Mike Mostafavi School: University of Phoenix Class: POS/355 One popular protocol for Linux Virtual desktop is SPICE it allows client and server to interact with virtual management tools and other standalone client applications. RHEV now allows management applications to run on Microsoft Windows server R2. V2V tools convert from ESX, RHEL Xen, and RHEL KVM to RHEV, the underling technology involved for V2V is called libguestfs, which is a library that binds programming languages to access Virtual Management disk images and interact with them in a variety of ways. VM’s can also work while the system is powered down. The draw-backs to using this system is that you must first obtain a license to use this feature, and it must be purchased before it can be used. Virtualization is becoming a key feature in the technology race for technology in the Linux system vendors, this technology provides a great advantage by letting the user aquire the ability to run powerful key features such as like image/storage management, clustering, system schedulars, power saver, ETC. By understanding what VR technology is capable of many companies are becoming more enthralled with what this technology can actually do, mainly in the world of medical science this technology was first discovered in its infancy as a way to seen through into the human tissue and muscle right to the bones of a person, this...

...OPEN SOURCE SOFTWARE What are reasons for business to use open source software? With the current economy difficulties, companies are trying to find areas in their businesses where they can save money. Many companies are having no choice but to let people go. Some businesses try to avoid lay-offs and instead are looking in other areas to save money. One of the areas is, of course, the IT department; software application acquisition is an area that might lead to a big money savings. Even in financially difficulties times, businesses want or need to improve their application environment. Sometimes it might even be necessary to invest in the IT infrastructure for long-term savings, which may result in the company not needing to close their doors. But many business owners or CEO’s will question if open source software is ready for business. This research paper intends to answer this question. The best reason to use open source software in a business environment is cost savings. This gives the business freedom to use software and change the source code in other words, modify how the software application is used, as it is needed. Open source removes the need for dependence on single vendor solutions and it provides very high quality applications and very good support. To understand open source software it is important to know what open source is, and what the meaning of open source software is. This research paper will also show where open source came from; the history of open...

...Installation Guidelines GRUB/LILO GRUB is the boot loader of choice for RedHat installations; however LILO may always be used in the case of most flavors of LINUX. GRUB/LILO can receive many different kernel level commands and it poses a major security risk if an attacker is able to compromise the kernel. In response you can make sure that only authorized users are able to perform those commands by password protecting during the installation process. If using GRUB, the password is by default stored as clear text, and so you will want modify the /etc/grub.conf file to store the password in an MD5 checksum. $ /sbin/grub–md5–crypt Password: (at the prompt enter the GRUB password you created at installation and press enter) $ #%t%661GFGftffgctTFTDd (This is the MD5 hash) edit the grub.conf file and replace the clear text password with the MD5 Hash. You must use the –MD5 option or the password will be stored as the MD5 Hash and not the encrypted password. Password – md5 $1$m0tLR/ $#%t%661GFGftffgctTFTDd Partitioning Partitioning correctly will help to mitigate against one specific type of denial of service. For example and attack designed to fill up a /tmp or spool directory. If your files are on the same partition as the directory under attack, your system could be rendered unusable. One should use a partition strategy where those directories that are most likely to be filled by an attacker. Typically this is /var and /home . If you are using a server for ftp or e–mail, you...

...SSL CIS341 Security Design in a Network Environment Professor John Dormishian Introduction The Secure Sockets Layer (SSL) is defined by Techtarget (2010) as a common employed protocol used for the management of security of information being transmitted over the internet. SSL has been recently succeeded by the Transport Layer Security (TLS), a protocol that is based on SSL. SSL operates on the program layer that is located between the Transport Control Layer (TCP) and then Hypertext Transfer Protocol. PCI (2008) referred to SSL as the established industry standard that is used in the encryption of the channel between a given web browser and an appropriate web server in order to ensure that there is privacy and reliability in the information that is being transmitted over the given channel. SSL is basically included as part of the web browsers as well as Web servers. Patel (2008,p.223) indicated that the SSL protocol was originally developed by Netscape in order to ensure that the security of information that is being transmitted as well as routed via HTTP,POP3 or LDAP was assured. The protocol had since then been adopted by Microsoft as well as other client/server developers as the de facto standard prior to its evolution into Transport Layer Security (TLS).The “sockets” in the term is used to refer to the sockets method of data transmission to and from a client/server based program in a network or even between various program layers in a common, same computer....

...Comment lines start with the # character. The Printer Configuration Tool allows users to configure a printer. This tool helps maintain the printer configuration file, print spool directories, and print filters.Red Hat Enterprise Linux 3 uses the CUPS printing system. If a system was upgraded from a previous Red Hat Enterprise Linux version that used CUPS, the upgrade process preserved the configured queues. Using the Printer Configuration Tool requires root privileges. To start the application, select Main Menu Button (on the Panel) => System Settings => Printing, or type the command redhat-config-printer. This command automatically determines whether to run the graphical or text-based version depending on whether the command is executed in the graphical desktop environment or from a text-based console.

...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...

...Risks and Resolutions Introduction A Computer Network has many benefits to a company. However, it also puts a company at security and privacy risks if they are not tackled with a profound technical know-how. When a computer on a network is hacked, there is a possible threat to other systems getting effected as well. These security breaches can be severe to the organization information and privacy and resolve into a loss of information, leak of confidential data such as bank accounts, and loss of goodwill and trust. Ping Sweeps and Port Scans Intro Ping sweeps and port scans are two methods commonly used by hackers to detect vulnerabilities on computer networks (InfoSoc, 2014). Hackers use ping sweeps to check on which computers are active and being used; while they use port scan to find open ports which can be used to breach a network. If these two methods are used by knowledgeable hackers, they can jeopardize personal data and cause severe effects on the entire computer network. Ping Sweep Ping is the abbreviation for Packet Internet Groper. It is a service to check if a machine on the network is up and running. In ping sweep, an Internet Control Message Protocol (ICMP) echo request is sent to a machine to see if it responds. If a machine is live, it will send an echo ICMP response. Hackers use this facility to seek targets in large networks. They use ping sweeps to continuously ping addresses, leading to a slowdown in the network. “It’s a bit like knocking on your...

...10/28/2013 LINUX James Tucker Unit 4 Exercise Ch 14 p. 582, Ex 1-5 1. Which commands can you use from the command line to send a file to the default printer? Redhat / Fedora 12 Answer: lp and lpr without arguments send their standard input to the printer. 2. Which command would you give to cancel all print jobs on the system? Executed as root, either lprn - or cancel –a removes all jobs from the print queues. 3. Which commands list your outstanding print jobs? lpc status shows a list of the print queues lpq shows what is in the default print queue lpq -Psomeprinter shows what is in a specific print queue 4. What is the purpose of sharing a Linux printer using Samba? Sharing a Linux printer using Samba allows windows and OS/2 clients to send print jobs to the printer. 5. Name three printing protocols that CUPS supports. Which is the CUPS native protocol? CUPS supports IPP, LPD/LPR, HTTP, SMB, and JetDirect (socket) protocols. Ch 10 p. 403, Ex 1 1. Describe the similarities and differences between these utilities: a. scp and ftp – scp is the "Secure Copy" program and it works just like the "cp", or "Copy" program, only it works through via the Secure Shell. ftp is the "File Transfer Protocol" and has nothing to do with security. Usually operates as its own interface with its own set of user sub-commands. Both are used to transfer files from one host to another via network connection. b. ssh and telnet – Both Telnet and SSH...
