Learning Log

Today I started open university, and in particular the unit NET11.

I completed the welcome materials and have read over the information in Module 1.

So far module 1 is straight forward, as I have covered these concepts before, but it is still good to revisit some of the more advanced concepts such as TCP/IP. I also didn't realize that you could TELnet straight from IE, which was quite interesting.

For the record I used good old MS-DOS to FTP rather than using a WSYWIG application.

Results from the required TraceRoute are as follows:

Trace complete


It looks a little scattered at the moment, I might want to work on the format.




Ping times for the webct site, vs the zdnet site actually came in at similar results, (around 200ms avg). Although that was webct.com, - both hosts are likely located in the USA and have similar hops between them. If I ping something local on the other hand, such as www.bigpond.com, the ping drops significantly - with a latency of only 23ms.
