Goal
The purpose of this lab is to establish a base environment to simulate that of an enterprise. Specifically we will be setting up at minimum four Virtual Machines using RIT’s RLES vCloud resource. Each one of the VMs created will serve a purpose in laying the foundation for future lab work. The first VM will serve as a router, bridging the newly formed virtual LAN to the network connected to the rest of the world. In my case I chose to use PFSense based on its simple configuration. Next I deployed a Red Hat Enterprise Linux version 7 server to act as the base on which my Wiki will run. I then deployed a Windows 7 client to act as remote manager of the other VMs. Lastly, I deployed an Opsview Atom VM to serve as my network’s monitoring solution.
I encountered several challenges which helped further my understanding of systems administration. The two tasks which I learned the most form where deploying the RHEL7 server, installing the Wiki and configuring my Opsview server. When installing the RHEL7 server, I made sure not to install the bare bones version of the OS, thus ensuring resources like a GUI would be available to me. However when I went to install the Wiki software, I realized that I should have chosen one of the other install configurations. Essentially, the version I had installed did not have any of the basic software suites that are commonly used to host websites on Linux servers. In the end I had to install Apache, Mariadb, and php before attempting to install the Wiki software. The next thing I learned was how to install and configure MediaWiki, which is the Wiki solution I have chosen to deploy. On specific issue I encountered was getting the HTTP traffic to my RHEL7 server to default to the main page of the Wi...

...r these requirements I have chosen PFSense as the router, Windows 7 for the client, and a Red Hat Enterprise Linux server hosting my MediaWiki database. It was my preference that the monitoring solution be given its own VM and so I have a fourth VM running an Ubuntu base with the Opsview Atom monitoring service installed.
I encountered serval challenges while achieving this configuration. Most of which were when I was installing the MediaWiki on the RHEL7 server. The two most difficult aspects where configuring the httpd .conf file to ensure that http traffic to the RHEL server would default to the MediaWiki main page. The other issue was discovering that SELinux was enabled by default, and as a result the firewall also need to be configured to allow incoming http connections. Overall this lab has helped further my understanding of Linux and Linux Administration.

Business ventures can benefit from virtual firewalls to protect access and data at lower costs than traditional methods. It is also beneficial to have an experienced security professional who is aware of your security needs. Virtual security involves the use of advanced controls such as a virtual switch to protect against malicious attacks coming from unverified sources. Applications are isolated to make them untouchable by malware, viruses and even applications that may stop execution (Marshall, 2011).
In this case I recommend for two types of virtualization in case of Regional garden limited company....

Open Shortest Path First (OSPF) is a link-state routing protocol which uses link state routing algorithm for Internet Protocol (IP) networks.Using OSPF, th convergence of a network can be done in very few seconds, loop-free paths can be guaranteed and better load-sharing on external links can be achievd. Every change in the topology of the network is identified within seconds using OSPF and it instantaneously computes the “shortest path tree” for every route using “Dijkstra's algorithm” . For that reason, OSPF requires a router which have a more powerful processor and more memory than any other routing protocols which leads to more elect...

A basic nmap scan of the entire VM image network will discover all available hosts. The subnet mask 255.255.255.248 only allows 6 hosts, so a rapid scan is expected. The basic nmap com...
Networks in organisation are dynamic and complex entities which can be quite challenging to configure and manage. (Kim & Feamster 2013). These corporate networks consist of multiple routers, switches, firewalls, middleboxes and a particular advantage of network management is the ability to monitor the entire business network. As all the devices are interconnected with many event occurring simultaneously, problems with once device can eventually lead and spread throughout...

First off, wikis could provide many uses for the educational environment. Not only is it easy to access and doesn't require fancy hardware or programs, it also encourages participation to take place. Wiki pages can be edited by either students or professors with each page relating to a topic or subtopic to the class unit; these pages can either be a collaborative or individual effort depending on the professor's choice. Each page can consist of an image or video gallery to support the text or have links provided for students to learn more information. Also, there could be forums to discuss the information further with fellow peers. David L. Neumann conducted a research project to analyze the effects of using wikis against individual (traditional) lectures. At the end of the researc...
