'''Working Draft!!!'''== Purpose ==
== Introduction ==In this assignment, you will use the '''335assign virtual network''' and the '''seedling''' cloning-source that you created in assignment 1 (part 1) to create two e-mail servers: a '''Mail Transfer Agent''' called '''pine''' and a ''Message Store'' (IMAP) called '''fir'''. You will also use the '''seedling''' cloning source to create a Samba server called '''bristlecone'''. In addition to creating those Linux servers, you will also be required to create a virtual machine for an MS Windows operating system to test-out your Samba server. As you perform and submit this assignment, you '''MUST''' run at least the '''balsam''' Master Name server in order to resolve domain names to IP addresses.
This course is a project course, and the majority of your mark will come from work on a Mozilla development project. The primary goal of this project is to get you involved in the Mozilla development community and codebase. Through this experience you will learn about the processes, tools, and practices involved in developing software as part of a large open source community.== General Requirements ==
== The Rules '''Weight''': 10% of Engagement ==the overall grade
Many of the practices inherent '''Due Date''': During Week 13 (in open source development will seem to go against the structures often set in place for similar course work. For example, you are typically forbidden to collaborate with your peers, to copy from the web, etc. However, these rules must be re-evaluated in the context of proper and pragmatic open source development practices.class)
First, consider the typical rules around cheating and plagiarism. In this assignment, you are encouraged to work within the set of best practices natural to open source development. Open source developers do not write from scratch what already exists and is freely available for use. You too should be thinking in terms or code reuse. It is ok for you to use code from other open source projects, so long as the license is amenable to the use.== Detailed Requirements ==
Second, consider the typical restrictions on peer-collaboration. In {{Admon/important|It is YOUR responsibility to Backup all of your VMs for this assignment, you Assignment!|You are encouraged required to frequently backup your VMs prior to exiting a work session during this assignment. Your instructor will NOT accept the fact that your hard disk crashed and lost all of your work together, . If you properly backed up your VM images and xml configuration files to help one anothera USB, then you can purchase a new hard-disk or wipe and recreate your hard disk and restore your VMs. Students who fail to look at each others code, etc. Open source collaboration is about leveraging submit their assignment #2 by the collective knowledge last day of a community scheduled classes will receive an INC grade (assuming they passed all of the other requirements for this course) and will be required to help solve show their instructor their working assignment #2 no later than 4PM on the problems first Tuesday of the individualnext semester; otherwise, they will fail the course. Students with accommodations should discuss arrangements regarding due dates / submission of assignment #2. Students that are missing both of assignment #1 and assignment #2 will fail this course.}}<br /><br />
Third, consider the sharp dividing line between student projects in most programming courses. For the most part, you are being evaluated on your ability to do a particular project or to solve a particular problem. Your outcome is measured against your peers’. However, in this course you are not in competition with your peers; rather, you are all working on one large project === Set-up Mail Transfer Agent (i.e., Mozilla'''pine''') with many sub-projects within it. As a result, there is no clean line to divide your work from that of your peers, your work from that of the Mozilla community. This means that collaboration with each other and even with other members of the Mozilla community is acceptable practice.===
To summarizePerform the following steps for this section:
* Help each other, contribute #Create a clone virtual machine called '''pine''' from the '''seedling''' cloning-source. Refer to the table below for '''address''' and '''hostname'''.#The normal user on your host machine must be able to ssh to the root account on each other’s projectsmachine without being prompted for a password.* Work with and #Create a '''regular user''' for this virtual machine using '''your Seneca userID'''.#Any machine within the Mozilla community'''coniferous.trees.ops''' domain will be able to route outgoing email through this server.* Give others encouragement and credit when they help you#Any mail sent directly from this machine will use the domain as the sending address (i.e. user@coniferous.trees.ops)* Use existing open source code whenever possible#You are NOT required to encrypt received email messages.* Be open to helping others and to being helped#This machine will relay received email messages for any user account in the '''coniferous.trees.ops''' domain.
== Requirements = Set-up Mail Delivery Agent / Message Store ('''fir''') ===
* Pick a project from Perform the [[Project List]]. If you want to work on something else, speak to Dave.* Create a project page based on the stubs in [[Project List]]--see [[Sample Project]] for an example. If someone has already created a page for a project you want to work on, speak to that person to see if you can join him/her. If s/he says yes, add your name to the Project Leader(s) section; otherwise pick another project and become a Contributor instead.* Become a Contributor following steps for one or more other projects. This is something that will just happen as you interact on IRC or in class. As people need help, you can choose to get involved with things. For example: helping to debug something, doing research into a problem, writing some tricky code. Over time your list of contributions to other peoples’ projects should grow. Keep track of this in a personal page. * Keep your project page updated. Add technical information to the Project Details section as you get a better understanding of the problem, and keep track of your project status in the Project News section. You should be updating this page at least once every two weeks and more likely every week. Remember that the more you write on your page the easier it will be to get help from other people: it is easier for people to understand your question with supporting documentation on the web.
