Task 3
Short Description of Task
Editing network settings on an existing CentOS 7 Linux system.
Long Description of Task
Using the existing CentOS 7 Linux system with a network connection created and set, edit the settings for the NIC by using nmtui and nmcli commands as well as /etc/sysconfig/network-scripts/ directory. The both commands are used for network configuration, but nmtui has a GUI mode and it is easier to use. On the other hand, nmcli has more advanced options. The directory /etc/sysconfig/network-scripts/ keeps all network interface files that start with the name ifcfg- and can be used to edit network settings.
Pre-Implementation Test Plan
• Ensure that the user is the root user or can use root privileges for commands.

• By using keyboard keys, choose Edit a Connection. Select the name of the network connection and on the right pane select Edit button.
• To change the profile name, delete the existing name and type a new one.
• Select IP configuration Automatic for DHCP or Manual for static IP address.
• For static IP address, type IP addresses with format (-- removed HTML --) /CIDR (Figure 3).
• Type Default Getaway address.
• Type DNS servers IP addresses.
• Select (-- removed HTML --) , if the configuration requires several IP addresses.
• Choose Automatically connect for IPv6 configurations.
• Select OK to save the network configurations.
• Select Back to go back Network Manager TUI.
• Select OK or Quit to go back to the terminal.
Edit network settings by using etc/sysconfig/network-scripts/ directory:
• In the terminal, open etc/sysconfig/network-scripts/ directory by using command cd etc/sysconfig/network-scripts
• List the files of the directory with the command ll. For more precise search, use pipes and grep filter: ll | grep “ifcfg”.
• Open the network configuration file with editor with root privileges sudo vi ifcfg- (-- removed HTML --) (Figure 4).
• For DHCP find the lines BOOTPROTO=none and ONBOOT=no and change them to BOOTPROTO=dhcp ONBOOT=yes and restart the network by using command with root privileges systemctl restart network.
The Windows CLI command that is used to display the search path for the executable files is _____.
From whatsmyip.com, I obtained my IP address to be 24.87.148.167. From that same website, I
The goal of this lab was to familiarize myself with the RLES vCloud Director, the vApps, and building virtual machines using RLES. I learned how to work with Red Hat Enterprise Linux 7 to build and customize servers built to meet the needs of my virtual environment. I also experimented with configuring pfSense to be my gateway between the virtual network and RITs RLES infrastructure. There was also the introduction of setting up both a wiki and a monitoring solution, which I chose to use MediaWiki and Nagios Monitoring Solution for my services.
That means the first 12 bits are fixed, the last 20 bits can be varied.
Leave “Mode” as Commixed. Transmute the SSID to the same one you utilized in Project 6-1. Click Preserve Settings. A page should appear denoting that your settings are prosperous. Click Perpetuate and you will be returned to the Wireless setup page
You can view your IP address for a NIC (or network adapter) by double-clicking one of the available connections in the Network Connections window (accessible from the Control Panel) and selecting the Support tab, just as you did when you were finding your MAC address. This information is also given in the Details window where you found the MAC address. What is the IP address of your NIC or network adapter? What is the IP address listed for your default gateway?
Network connection error can take place on your Windows 8 machine. Whenever you try to open any browser such as Google Chrome, Mozilla Firefox or Internet Explorer, an error message may come up. According to the message, network connection fails to get established. Therefore, browsers
NOTE: Please write your answers to each question in a different color font to make this easier for the Professor to grade.
You can download many utilities from the Internet. Examples of utilities are cp (copies a file), ls (lists information about files), ssh (securely connects to a remote computer), and df (lists information about free space on system devices such as hard disks).

In the workplace today there are many different options for operating systems be they providers of server related services or end-user desktops there is a different Linux distribution for many different applications. There are also a number of advantages and disadvantages to adding onto or switching network operating systems within a company. In the following pages I
Linux is a trademark owned by Linus Torvalds [1]. It is an operating system which is powerful, free and inexpensive to own based on UNIX [1]. It is a POSIX-compliant with versions available to install in cell phones, supercomputers and most computing systems [1]. Linux is an open source program as its source code is available to the general public for use and the right to modify from its original design without any charges [1]. New code will be added to the next version made available with Linux if it is accepted as a universal improvement [1]. The code will continue to exist and developed by the user even if the company fails [1]. Moreover, updates for Linux are available every six months [1]. Nowadays, Linux is in constant development by
There may arise a necessity to change the network operator which can be done by eUICC
The Linux was originally founded by Linus Torvalds. In 1991, he was a second year computer science student in Finland. He sought after an operating system that was similar to the UNIX system, but both UNIX and the hardware it ran on were excessively expensive. A UNIX version called Minix was available for free, but it did not reasonably meet his needs as it was simply an operating system for students, designed primarily as a teaching tool rather than an industry strength operating system. As a result, Torvalds studied Minix and proceeded to set out to write a new version. After six months of working to produce the new operating system, Torvalds made very little progress toward the utility of the system.
Docker creates a pair of virtual Ethernet interfaces on each container, randomly assigning them an IP address and a subnet from a private address range not already used by the host system. When you install docker, it creates three networks automatically.
