After reading the content of module 1, I performed the required tasks.
Telnet
The first task consisted of using Telnet. I previously used telnet sessions in my previous work, which was based opening a telnet session from my client computer which then linked to a server that then opened an application to be used for various purposes. I have not used Windows telnet before, so I did a little bit of navigation along the way. It was easy to use and the commands from the “help” section were clear. The task was performed accurately (I hope) as an email from the library was sent confirming my enquiry.
The second task involving Telnet required a session to towel.blinkenlights.nl. This destination shows an animation of Star Wars. It was quite clever, however I had some trouble “breaking out of the session”. It shows that the remote login session can trigger an application run by the destination address. The interface may appear to be somewhat “ancient” these days, but I found it quite interesting as I am use to DOS and command line type sessions from previous work requirements. However, I think the “youth” of today would prefer a GUI with more advanced graphics and possibly interaction.
FTP
This task consisted of using FTP to answer a question. I used Windows ftp from the command prompt. A bit dusty on my FTP commands so I had to checkout the help by typing ? at the prompt once I was in. I used the “get” command to download the file which revealed the answer to the question (I hope I am right).
Therefore, the answer to the question is CAPITALISATION. This is pretty fun to do and certainly more enjoyable than performing exercises out of a text book (which I am also doing for another subject). Below is a snippet from the readme file:
* ATTENTION MAC, OS/2, MS-DOS and MS-WINDOWS users:
This server runs on a unix platform, so CAPITALIZATION MATTERS
FTP is a great tool to move files around, access files and or analyse files. However, if not secured properly, I think it would be a security nightmare. I wonder what permissions were set on anonymous login?
Internet Tools
Traceroute – first I pinged curtin.edu.au from my pc to obtain its IP address (use the ping –a command) then went to network tools website (http://network-tools.com/) and ran a trace to determine the route. I think the traceroute command may be useful in analysing offline problems such as determining if a “route” is down, hence preventing the packets to reach its required destination.
The results were interesting showing each “hop” or route as it went and then timed out, assuming it had reached its destination:
134.7.177.136 is from Australia(AU) in region Oceana
TraceRoute to 134.7.177.136 [curtin.edu.au]
Ping – a ping was performed to determine response speed using net tools website and my pc. The first result was using my pc. Again, I determined the IP address of Webct using the –a option in ping. The results were interesting leading me to think that it was quicker to get a response from net tools than my own pc. After a couple more tries, the speeds did change but not by much. Maybe someone can comment on why?
Results from PC:
C:\>ping -a http://webct.curtin.edu.au/webct/homearea/homearea

5 Tips for New Bloggers
I have come to realise in its most simplistic terms, that a blog is a web page or site whereby the blogger expresses their opinions and observations. Furthermore, a blog has been described as an online journal or diary. This blog will not be dissimilar to a journal whereby my experiences with net studies will be posted.
As I am new blogger, I went searching on the Internet to find tips on how to blog. It was interesting to see the vast array of opinions that people prescribe to blogging, however there were some common themes. Generally, these include linking freely, make posts interesting and the general formation of your blog site. Below is a summation of tips that I believe will be of use to me and hopefully whoever else is a newbie looking for some hints.
1. Define your Purpose
Determine why you have created a blog and what you want out of it. I guess this comes back to the definition of blogging ie. Opinions and observations. This tip is useful for me, as I can continuously develop and post useful and meaningful content and maybe reach a goal.
2. Enable Comments to your Postings
Blog posts can enable or disable comments. In this blog, comments on posted topics will be very useful for my learning. I feel it is the same for any blog. By enabling comments to postings, it encourages conversation and provides for alternate opinions from peers and other sources. This too is a learning mechanism, whether you take it or not.
3. Credit the Sources of your Posts
If you have ripped off someone else’s stuff and put it up as your own, you may end up with “egg on your face” for the world to see. It is simple to add links to the source of your post, you can always agree with the original source and specify that opinion.
4. Blogging is a Social Experience
Your postings are there for everybody to see, so be nice to others who have differing opinions if you want to maintain a positive experience from your blog. This may also be reciprocated by users of your blog and could even promote long term relationships with users. However, the tip does not mean you can’t disagree or provide an alternate view with the comments posted, just be nice about it. I guess this comes under blogging etiquette.

5. Participate in the Blogosphere
Get to know more about blogging and posting comments on other blog sites. Get used to updating posts on your blog on a regular basis. Experiencing other blogs can provide ideas for your own blog site if endeavouring to improve the experience for both yourself and the users.

Finally found time
Finally, I have found some time to add to my newly created Netstudies Blog. Time to dump all the findings from the readings and tasks onto the site. A bit of research on blogging was required also, as I have never done this before. It is interesting to see other peoples views are on this communication network. Particularly when providing tips for beginners.
Course readings have been interesting and simply a revisit to my days when I worked in IT Operations. Telnet, FTP and networking commands have all be revisited.
