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. 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.
General Requirements
Weight: 10% of the overall grade
Due Date: During Week 13 (in class)
Detailed Requirements
Set-up Mail Transfer Agent (pine)
Perform the following steps for this section:
- 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 machine without being prompted for a password.
- Create a regular user for this virtual machine using your Seneca userID.
- This machine will accept incoming email for any user account in the coniferous.trees.ops domain and any named machine in that domain.
- Any machine within the coniferous.trees.ops domain will be able to route outgoing email through this server.
- Only the address associated with pine.coniferous.trees.ops will be used for SMTP.
- This machine will use postfix's built-in LDA, and will store mail in maildir format, placing each users' mail in a sub-directory of their home directory called mail.
- This machine will provide users with unencrypted remote access to their mail boxes through dovecot using IMAP. Note that this access will only be available to machines inside the coniferous.trees.ops network, and only through the ip address and hostname for fir.coniferous.trees.ops
- No other machine in the domain will accept email.
- Any mail sent directly from this machine will use the domain as the sending address (i.e. user@coniferous.trees.ops)
- All mail sent to this network should automatically be redirected here using DNS.
Set-up Mail Delivery Agent / Message Store (fir)
Perform the following steps for this section:
- Create a clone virtual machine called spruce from the seedling cloning-source. Refer to the table below for address and hostname.
- Create a regular user for this virtual machine using your Seneca userID.
- Setup a DNS server on your spuce virtual machine with noting the following items below:
- This virtual machine will be the Slave DNS server (in case the Master Name Server goes down).
- This virtual machine will obtain its zone files by copying them from the Master Name Server.
- This Slave DNS server will check for updated records from the Master DNS server every day. If the initial attempt fails, then it will attempt every hour until it succeeds.
- This machine will provide forward and reverse lookups of ALL virtual machines in the coniferous.trees.ops zone, the zone files for which will be obtained from balsam.coniferous.trees.ops.
- Only machines within the coniferous.trees.ops domain will be allowed to query this machine.
- This machine will not provide recursive lookup capabilities for any machines.
Network Configuration
As you will now have functioning primary and secondary DNS servers, modify your network configuration file on these machines and on the cloning source to specify the correct IPADDR.
Table of Virtual Machines / DNS Records
All the machines in the following table require DNS records. The rows not shaded represent future servers that will be created in Assignment #2.
Hostname | Address | Purpose |
---|---|---|
spruce.coniferous.trees.ops (your existing source) | External Facing Address: DHCP assigned Internal Virtual Bridge (virbr1): 172.30.20.1 |
Your host machine |
seedling.coniferous.trees.ops | 172.30.20.100 | Cloning-source used to create other servers for other assignments. |
balsam.coniferous.trees.ops | 172.30.20.2 | Master Name Server |
spruce.coniferous.trees.ops | 172.30.20.3 | Slave Name Server |
pine.coniferous.trees.ops | 172.30.20.5 | SMTP mail Server |
fir.coniferous.trees.ops | 172.30.20.6 | IMAP mail Server |
bristlecone.coniferous.trees.ops | 172.30.20.8 | Samba Server |
Set-up Firewall Policies
In addition to the basic firewall established in assignment 1, ensure the following restrictions are met:
- Any machine may query balsam
- Only the machines in the coniferous.trees.ops network may query spruce.
- Only spruce is allowed to get zone transfers from balsam
Assignment Submission
The student is required to prove to their professor that their set-up works correctly during the regularly-scheduled lab period.
Assignment Evaluation Details
- Demonstrate working assignment to your instructor in class:
- Students need to demonstrate their assignment functionality to their professor during a lab period
(like you would for any lab for "sign-off"). - Students are required to prepare everything ahead of time so that you can quickly demonstrate to your instructor that all required parts of your assignment are working.
- Do do proceed to the next step until you have demonstrated your assignment to your instructor to check for errors that may cause problems when running the checking script.
- Students need to demonstrate their assignment functionality to their professor during a lab period
- Download and run a shell script to check your work (Depending on your OPS335 Instructor):
- Peter Callaghan's Classes (Sections C & D):
- Refer to instruction on Moodle to download and run marking shell script.
- Peter Callaghan's Classes (Sections C & D):
- Murray Saul's Classes (Sections A & B):
- Login as root on your host machine.
- Change to the /root/bin directory.
- Make certain that both your balsam and spruce virtual machines are running.
- Issue the command to download a checking script for your assignment to your host machine:
wget http://matrix.senecac.on.ca/~murray.saul/ops335/check-assn1-p2.bash
- Set execute permissions and run the command: /root/bin/check-assn1-p2.bash
(You shell script contents will be mailed to your Seneca email and to your OPS335 instructor's Seneca email. If you do NOT receive an e-mail message in your Seneca email account, then there is a problem, and you MUST rerun or contact your OPS335 instructor immediately.
- Murray Saul's Classes (Sections A & B):
- Additional Assignment Information:
- This assignment is to be completed individually. Group submissions are not allowed.
- You are NOT allowed to use local hostname resolution (i.e. no entries in your /etc/hosts file).
- Test your machine to make sure it works. If a machine is not accessible (e.g. will not boot, can not be accessed through ssh from your host, etc.), or is otherwise non-functional, you may be told to resubmit.
- Late submissions are a subject to a penalty of 10% per day.
Evaluation Rubric
Here is an evaluation rubric (in table form) showing you how you will be evaluated for this assignment. Part of the rubric is marked from professor observation from student demonstration of assignment in class, and the other part is based on output from the results of an assignment checking script that the student will download and run.
