TELNET:
I had some trouble with this originally, as I understood from the lesson notes that we had to download a program, which didn't work, and threw me way off track. Then on the forum someone mentioned that windows has it's own function so tried the following .. Start:Run:Telnet, which opens the windows telnet function. Once I took this approach the rest was easy.
... Type: 'o' for open, http://www.library.deakin.edu.au/ ,'v' for VT100, 'y' confirm, 'a' for author, 'Bennahum' etc....
The email response I received was:

I must be lucky then. Mine only took a couple of minutes to reach
my oasis email, and only slightly longer to reach yahoo.
FTP:
This was relatively easy. Pretty much just a case of following your nose through the links etc. to find the document and then the wording to for the answer, (CAPITALIZATION).
INTERNET TOOLS - Traceroute:
This exercise I found easier. I have used this once or twice (a long time ago though).
Below is the 'cut n paste' of the entire list of 'hops':

Trace complete
How many ‘hops’ are there? Therefore there are 23 hops
What is the average time in milliseconds from the tools site to the curtin server? Approximately 245 rtt (not real sure what rtt is, I've emailed the support/help desk asking but haven't rec'd a response yet).
The ip address is slightly different to that in the self test answer, but that is explaind best by Cynthia's comment below:

Hi Dew,
I think that task may need updating as terminals for functions change -
we have many terminals on campus and have also expanded terminals and
uses so you may find that addresses change a lot. Don't worry about the
self test in that respect also- its a bit old.
cheers

After reading this I redid the ‘self test’ links and got 3/3. (Previously I got 2/3 due to the different ip address).
Further Exploration: Ping and, Traceroute
Is ping quicker or slower? I completed the following:
Start>run>cmd ... tracert curtin.edu.au - this was quicker taking 85ms! I also used: ping curtin.edu.au - this taking 86ms
Therefore ping appears to be quicker than the original traceroute exercise.
Why?
Ping sends out a request and measures the time it takes for the response to return (like drawing a circle. Traceroute uses TTL 'Time To Live' to solicit a response and measures this time at each hhop. (Like counting the time while it waits at a base (baseball) before it is allowed to run to the next base/hop).
More information can be found at http://www.capnet.state.tx.us/traceroute.html
Actually this exercise has been useful in the sense that shortly afterwards I had to set up a LAN (local area network), where using ping was quite useful for troubleshooting the connections! It’s always nice to be able to put ‘theory’ into real life practice!!
REFLECTIONS:
During the Telnet exercise I did suffer Concept 23 ‘Human-computer interfaces’ because I experienced the impersonal aspect of dealing with a machine (1). I hope that other communication on the internet quite as bad! I don’t believe it is. Despite I communicated with other humans at a distance of the forum, I found this much less impersonal, and much more helpful. Therefore, in this case I don’t think this concept is accurate – to assume they are the same (or similar) experience.
As Concept 24 ‘Client-server two-way interactions indicates, FTP is a great example of two-way interactions (1). Conversely, HTML is closed for example, (well it doesn’t remain open like a telephone line waiting for an ‘answer’ – once it’s done its job it closes the connection); it requires human intervention (a response) to keep the ‘communication’ flowing).
I can see some sense in Concept 25 ‘Identity and location’ which explains and understanding of these tools/exercises, goes some way toward explaining why sometimes one’s online experience seems slow (1). I still think it is odd though – I still see my ‘identity’ as ‘here’ where I am sitting at my desk, with the pc plugged into the wall in front of me, and so have trouble considering that my ISP is not even local! Location and identity are interesting concepts to consider within the realm of WWW…
