CNT4704: Analysis of Computer Communication Networks
Fall 2012
Lab assignment 2: Manually send a spam email
(Assigned on Oct. 2nd, Due Oct. 9th midnight via WebCourse)
In this simple assignment, you will need
to
use
telnet to manually send a spam (faked) email to Dr. Cliff Zou to
this account "ucf.cnt4704@gmail.com". From this
experiment, you will understand why there are so many untrusted
email
around and how easy for attackers to send out spam or phishing
email. Due to our department email server's security policy, if
you use our department email server for this task, you need to
first SSH to eustis.eecs.ucf.edu, and then do the telnet
interaction on eustis machine.
Please follow the in-class illustration to send this faked email. In order to make these assignment email not be treated as the other spam email, you must follow the following specifications:
1. The sender email must be "fake@", you can use any domain name in the sender email address (but do not use cs.ucf.edu, longwood.cs.ucf.edu, or eecs.ucf.edu).
2. The email must have a subject line as "CNT4704: firstname lastname". Put your name in the subject line so that you can be credited.
3. Put in some words in the content. Must be at least two lines.
You can type in two "rcpt to:" to include your own real
email
address for
verification to check whether your email has sent out
successfully or
not.
What to Submit:
1. You need to send this spam email by Oct. 9th
midnight.
2. You
need to submit an assignment report via webCourse.
In this
report, you MUST include the image of screen copy of
your
command shell window. The screen copy should clear show what you
typed
and what
the
server responded.
In some case I may not be able to receive your spam email,
but
I will still give you full credit if your report shows that you
have
used telnet correctly in manual email sending. Some students can
use their ISP's email servers for this task as well.
