== Purpose ==
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.

{{Admon/important|It is YOUR responsibility to Backup all of your VMs for this Assignment!|You are 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. If you properly backed up your VM images and xml configuration files to a USB, then you can purchase a new hard-disk or wipe and recreate your hard disk and restore your VMs. Students who fail to submit their assignment #2 by the last day of scheduled classes will receive an INC grade (assuming they passed all of the other requirements for this course) and will be required to show their instructor their working assignment #2 no later than 4PM on the first Tuesday of the next 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 />
=== Set-up Mail Transfer Agent ('''pine''')===
#Any mail sent directly from this machine will use the domain as the sending address (i.e. user@coniferous.trees.ops)
#You are NOT required to encrypt received email messages.
#This machine will relay received email messages for any user account in the '''coniferous.trees.ops''' domain and any named machine in that domain to the IMAP server (i.e. the '''fir''' virtual machine).
=== Set-up Mail Delivery Agent / Message Store ('''fir''') ===
#Create a '''regular user''' for this virtual machine using '''your Seneca userID'''.
#The root user on your host machine must be able to ssh to the root account on each machine without being prompted for a password.
#This machine will accept incoming email for any user account in the '''coniferous.trees.ops''' domain and any named machine in that domain.
#No other machine in this domain will accept incoming email.
#This machine will be an '''IMAP ''' server (i.e. NOT POP3 or LTMP).
#This machine will NOT use encryption.
#This machine will be used use postifx's built-in LDA to store received emails in MBOX maildir format in the a sub-directory of each users' home directory /var/called mailboxes.#Any mail/mailboxessent to root will be automatically delivered into the mailbox of the '''regular user''' created above.#Configure your Thunderbird application (installed in Lab 4b) to allow the user to send and receive email messages using the '''pine''' and '''fir''' servers.
Add MX records to the forward lookup zone on your balsam DNS server so that all incoming mail addressed to the domain is sent to your IMAP server ('''fir''') first, and the MTA ('''pine''') as a fall-back.
=== Set-up a Samba Server ('''bristlecone''')===
#The normal user on your host machine must be able to ssh to the root account on each machine without being prompted for a password.
#This machine will use the master and slave DNS servers in your domain as the primary and secondary DNS servers. It will not have access to any other DNS servers.
