Email Tasks

1. What information about a user's email, the origin of a message, and the path it took, can you glean from an email message?

As you can see from the first image of my yahoo inbox, there are four fields with information relating to the message 'From, Subject, Date and Size'. If you look at the first message it has been sent by Smith Micro, we can tell where the message originated from. The second field 'Subject' informs us that the email is advertising, 'Special 40% Store Wide Sale this weekend only', this field informs us of the content. The 'Date' tells us when the message arrived in the inbox and the 'Size' field tells us how big the message is.

The second image I have used is of my mail inbox, this image shows an example of a 'Signature' (highlighted in blue). 'Signatures' tell us a lot of information about who is sending the email. Signatures can contain the senders 'name, job title, email address, postal address, phone and fax numbers and website url'.

2. In what cases would you find it useful to use the 'cc', 'bcc' and 'reply all functions of email?

'Cc:' short for 'carbon copy', is useful in that it lets you send a word for word copy of your email to other recipients. You can enter multiple recipients in the 'Cc:' field separating the addresses of the recipients with a comma.
The negative issue with 'Cc:' is every recipient that receives the message you send using 'Cc:' sees the 'To:' and 'Cc:' fields with all addresses displayed. To stop this issue from arising the 'Bcc:' function is useful, when using 'Bcc:' "the only recipient address that will be visible to all recipients is the one in the 'To:' field."
Similar to the 'Cc:' function the 'reply all' function will send a message to everyone who initially received the original message.

3. In what ways can you ensure that an attachment you send will be easily opened by the receiver?

Firstly within the message you should make the recipient aware that there is an attachment for them to download and view.

Then make them aware what format the attachment is in and what application is required to open and view the attachment.

I would also make them aware why they need to open and view the attachment.

4. What sorts of filters or rules do you have set up, and for what purpose?

Currently I don't have any filters or rules in place, before this tutorial I was not aware that these functions could be so useful. I am intending on implementing a rule that splits emails received intended for my wife and myself, as one of our email account's is shared.

5. How have you organised the folder structure of your email and why?

As you can see in the image I have seven sub folders under in my '.mac account'.

The folders are structured to make future access simple and easy. The dodo folder simply archives phone bills and provides a reference as to how much we are spending on communication. The software folder contains serial numbers and passwords so this folder will be accessed if I was to upgrade machines and need to transfer software to a different computer.

How many ‘hops’ are there?

19

What is the average time in milliseconds from the tools site to the curtin server?

50.000 ms, I am amazed at the speed this tool is very very cool.

Looking at these results, find out the IP NUMBER of the hostname curtin.edu.au?

134.7.179.56

mac has bundled these tools in Applications-Utilities-Network Utility

Ping the Blackboard site and compare the time with the time taken to ping from the net tools site. Is it less or more than you expected?

When I used the ping function in the Network Utility and entered: http://lms.curtin.edu.au/webapps/portal/frameset.jsp I was presented with the following error: ping: cannot resolve http://lms.curtin.edu.au/webapps/portal/frameset.jsp: Unknown host

After reading the posts on the discussion board(Course Discussions: Module 1: Internet tools task)

I found that I was entering the url of the blackboard site incorrectly so when I use the correct url of lms.curtin.edu.au it worked correctly

Traceroute from your computer to curtin.edu.au: compare the number of hops with the earlier traceroute.

The initial part of the traceroute stages 1 through 9 were extremely fast and then the process slowed and took around 15 seconds to complete.

FTP: file transfer protocol

You are to ftp to recall.curtin.edu.au . You will use anonymous login. When there:Look at the directory structure.Find the file called README Then download the file, look at it and answer the following question "according to the readme file, '_______ MATTERS' - what word goes in the blank?".

According to the readme file CAPITALIZATION MATTERS!

I found that the recomended application for mac called fetch was very easy to use and made ftp fast and effective.

Having stumbled my way through ftp previously I found this task to be extreamly informative, I surfed around for some more helpful information in regards to ftp. I found an article on ftp at http://personalweb.about.com/od/ftpfileuploadprograms/a/01ftp.htm that explains the procedure
in a strait forward manner. In this article Linda Roeder advises to "set up the folders on your hosting service exactly the same as you set them up on your computer so you will always remember to send your files to the correct folders."

TASK B
If telnet leaves you unimpressed, and you much prefer the contemporary web-based library catalogues, then 'do yourself a favour' and telnet over to towel.blinkenlights.nl for a bit of fun!

I have tried to perform task B today and I have received the following error codes:

"You are not welcome to use sshd from 122-148-198-204.static.dsl.dodo.com.au."

"Error connecting to towel.blinkenlights.nl, reason:
-> Error in ssh2: I/O error in version negotiation{com.mindbright.ssh2.SSH2FatalException: I/O error in version negotiation}"

After trying a few different things within mindterm I have found where I was going wrong:

I was entering "towel.blinkenlights.nl" in the first screen as below.

"MindTerm home: /Users/kurthenson/.mindterm/
SSH Server/Alias: towel.blinkenlights.nl"

To connect correctly I go to "plugins" and then to "telnet terminal" and from there a new screen opens and you receive the following
"Not connected to ssh2 server, can only make direct connections.

remote host[:port] : "

Where I simply added "towel.blinkenlights.nl"

From there you get to view an amazing version of starwars, very very impressive.

TASK A:
But, in this task, we are going to learn about telnet for a very important purpose, perhaps the main one that 'information seekers' rather than programmers need to use: logging on remotely to a library computer to access its records. The aim is to show you what can be achieved by using a more traditional information system, rather than 'the web'.

What to Do:

First you need a telnet client for your computer (you may already have one installed - try typing telnet:// in the URL box of your browser). The two we recommend are Windows Telnet (for Windows - free) and NCSA Telnet (for Macs - free): there are others, however – feel free to explore for yourself. Vista users may want to read this for more information Windows Vista Help : Telnet.

Download and install your chosen client and then explore one for your system.

Next: You are to telnet to the Deakin library database computer. The address is library.deakin.edu.au.

The search will be done by author. Find books with the author name Bennahum then in the Options menu, choose print this title. You will then be prompted to enter an email address to which this record will be sent. Enter your curtin email address.

LOG ENTRY:
Not sure about the advised NSCA telnet app for Mac tried to open it after download but was unsuccessful. Googled my way to Mindterm located at (http://www.appgate.com/index/products/mindterm/) . Mindterm is a “small, portable and secure. It is very powerful and easy to use and provides advanced features such as tunneling support, GUI-based file transfers and support for proxy traversal. The client also includes an integrated terminal emulator with support for several different terminal types and it has the ability to run both as a standalone application and as an applet.” But I will have to take their word for it as I am a complete telnet novice.

Next: You are to telnet to the Deakin library database computer. The address is library.deakin.edu.au.
Error connecting to library.deakin.edu.au, reason:
-> timeout when connecting ??????
