...Project Student College Case Project Linux as an operating system is a powerful tool used in businesses for its secure kernel and command line interface. From a small business to a large enterprise, Linux is used to run servers, store vital information and documents. In Outdoor Adventures, this store needs a more efficient computing system. The system will need to keep information available and secure enough to ensure that the information can only be seen by the right people. To help keep things organized, a file structure will also be required to keep all the files with special permissions together for easy access. To better illustrate the security capabilities of Linux Ed Sawicki of Biznix.org said, “The Linux firewall has functionality that rivals expensive commercial firewalls. Its rules allow fine grained control over stateless and stateful packet filtering. The Linux firewall is extensible, allowing new filtering capabilities as the need arises.” This comparison is powerful when considering what would be the most cost effective direction for a business, but also the safest. Another advantage of linux is that it is generally free to try before applying it to a commercial setting. The product can in effect speak for its self by allowing itself to be made publicly available so there is no need to consider it a “business risk” when a technician can experiment with it first before applying it on a much grander scale. “Linux…is a freely available multitasking and multiuser...

...software applications can operate accordingly. Operating systems can be found in almost any type of a computer device such as personal computers, supercomputers, cellular telephones, and video game consoles as stated by Linux Systems (2011). As the research was being conducted for this paper, it raised a question whether the internet uses the operating system? It proved to be a challenge to actually pin point the most common operating systems on the Internet, but as the research continued, it was obvious that these three, Windows, Mac OS X, and Linux are considered to be the most common operating systems used on the Internet today. Background of each Operating System Windows Privately owned operating systems, Microsoft Windows is generally used on personal computers and as of today, the most commonly used version is Windows XP with the new version of Windows 7 for personal computers and Windows Server 2008 R2 for servers is entering the market.

...Exploring Linux Operating Systems What is Linux? Linux is an Operating System for a computer; it is like other Operating Systems such as Windows and the OS X for MAC. Linux was created in 1991 and has been found on many different systems like Super Computers, cell phones, and even the New York stock exchange. What sets Linux apart from other Operating Systems is that Linux is made by several different companies. According to www.linux.com over 3,200 developers have from 200 companies have contributed to the kernel which is just a small piece of the distribution. How is Linux used today? While other Operating Systems are very limited to personal computing devices, Linux is not limited it can be found on many different things. Linux had its start as a server Operating System but is also one of the only Operating System that can be found on more than just a personal computer. Some of the different things it can be found on taken from www.linux.com “These are just the most recent examples of Linux-based devices available to consumers worldwide. This actual number of items that use Linux numbers in the thousands.” www.linux.com File Editors Coming from a Windows Operating System pretty much my whole life, which means I only have experience with GUI editors such as Notepad from Windows.

Assignment Requirements As the Linux system administrator of insurance company Secure All, Inc., you need to design firewall rules for the organization’s bastion host file server, which uses Samba. This server is located in the local area network (LAN) with the network address 172.16.0.0/12 and subnet 255.240.0.0. The server should also allow Web application access for its online transaction platform to mount the filesystem. The Web application resides on the Web server located in the demilitarized zone (DMZ). This server has two interface cards. One card, which is for the traffic from the DMZ firewall, is linked to the wide area network (WAN). This card’s IP address is 192.168.1.5. The other interface card has the IP address 172.16.1.5 and is linked to the LAN. Which firewall rules should be written using iptables for the server hosting Samba? Discuss and suggest firewall rules to allow administrators to remotely manage the server using SSH. Use the concept of “default deny” when designing the rules.

...Chap 18 Pg 699 Q1 difference between scp and sftp utilities? SCP is a secure file copy utility and SFTP is a secure file transfer protocol even though it does not have anything to do with the FTP we are use to in windows. Q2 How can you use SSH to find out who is logged in on a remote system? By typing $ ssh host who in the terminal window Q3 How would you use scp to copy ~/.bashrc file from the system named plum to the local system? From the local system you would type scp user@plum:~/..bashrc local system: .bashrc. Q4 How would you use scp to run xterm on plum and show the display on the local system? Having the same username on both systems and the X11 server running locally, the command to run xterm from the plum system and show on the local display is $ ssh plum xterm Q5 What problem can enabling compression present when you are using ssh to run remote X applications on a local display? Compression can cause an increase in latency to an extent the might not be desirable for an X session forwarded over high-band width connections. Q6 When you try to connect to another system using an OpenSSH client and you see a message warning you that the remote host identification has changed, what has happened? What should you do? This indicates that the fingerprint of the remote system is not the same as the local system remembers it. Check to find out if something changed. If everything is ok, get rid of the remote system’s key from the file located in the error message and...
