Hello and welcome to my first ever Blog.
Well...week one of unit net 11 is over and I've read the orientation info and introduced myself to my tutor and classmates on the discussion boards, noticing that there's quite few people (my face racked with fear) with much more advanced IT skills than me.
Week 1 was interesting as I tried things that I'd never attempted before, probably because I've never needed too. But I persisted and eventually, after a couple of attempts just to make sure I did them right, successfully completed the module 1 tasks (more on that soon).
Next came the setting up of a web space for my learning log, assignments etc. in the presentation area, after some quick begging emails to classmates I managed to get it up and running. But there are still a few things needed to be tweaked.

Telnet: I've never used Telnet before, but I have heard the name mentioned never really knowing what it was, so I was interested to try it out for the first time. I used the Windows Telnet client for this exercise, at first I didn't know the commands, but after checking out the help files I quickly got a grasp of the Telnet commands. (Help files are very helpfull :-) )
I followed the module instructions and successfully completed the task by finding the author and emailing the info to my student email account at Curtin. The answer to the self test is 'Managed care, Finacial, Legal and Ethnic Issues' I also searched the web for more infomation about telnet and found this summery.
What is telnet?
Telnet is a protocol that allows you to connect to remote computers (called hosts) over a TCP/IP network (such as the Internet). You use software called a telnet client on your computer to make a connection to a telnet server (i.e., the remote host). Once your telnet client establishes a connection to the remote host, your client becomes a virtual terminal, allowing you to communicate with the remote host from your computer. In most cases, you'll need to log into the remote host, which requires that you have an account on that system. Occasionally, you can log in as a guest or pblic without having an account.Telnet clients are available from all major operating systems.

File tranfer Protocol: Again I've never found it necessary to use a FTP client, but once I had installed the recommended WS- FTP software I was surprised how simple it was to use. I used an anonymous login and tranfered the necessary readme file and answered the missing word in the self test question 'Capitilaztion'. I found additional infomation about FTP at the following link. http://wwwftpplanet.com/ftpresouresbasic.htm
Also after reading Melissa's blog I downloaded Filezilla to give it a try (more on that later)
Internet Tools: Traceroute & Ping
The Traceroute utility checks how many "hops" (transfers through other computers on a network it takes for your computer to contact another computer). You can use traceroute if you know the other computer's IP, web site address, or name.
For this task I used the following link http://centralops.net/co/ and used the traceroute utility found there.

Trace complete
In this trace route it states that the IP number is 134.7.134.47 But the self test states it as being 134.7.134.101. the last few digits are different , I'll have to make some investigations to why?( read the discussion boards or ask classmates ) It also took 23 'hops' to reach Curtin.
It's interesting to see where in the world the hops are and what route it takes.
Ping ?
Ping is a program that sends a series of packets over a network or the Internet to a specific computer in order to generate a response from that computer. The other computer responds with an acknowledgment that it received the packets. Ping was created to verify whether a specific computer on a network or the Internet exists, and is connected.
Some have claimed that the word "ping" is actually an acronym for "Packet Internet (or Inter-Network) Groper", deliberately contrived to play on the fact that pinging with a computer is similar to what submariners do with sonar. Both the computer and the submarine's sonar send out a "ping", in the form of either a series of packets or a brief burst of sound. The ping "bounces" off the target and then returns to let you know the target is there.Ping is both a noun and a verb, e.g., "Ping that computer", or "the router didn't return a ping".
Ping is built into almost every network-capable operating system. To ping a computer, go to a command prompt and enter ping , a space, and then the network or Internet address you wish to contact.
