GOOGLED: net neutrality (AND; Some of the links pasted below)

Friday 12, 2010 – The group, Anonymous, blocked the main government website www.australia.gov.au and www.aph.gov.au, the Australian parliament’s homepage, for a second day running in protest over controversial plans to filter the internet.

Codenamed “Operation: Titstorm”, the hacking campaign involves hundreds of people from around the world and used a technique called Distributed Denial of Service (DDoS) to jam web traffic, one of the protesters said.

The main-stream media (TV) – is not reporting on this much (Or, I have stopped watching), and so, ..  ANY good ‘Internet-Search’ reveals a wealth of information on these topics).  – I hope to follow up soon on this topic, from the technical angle, without the political-hype, lies, and deception provided by bias reporters, and hence provide my-own biased opinion.

TED – 4chan’s moot takes pro-anonymity to TED 2010

In the closing minutes, moot’s purpose for speaking became clear: he insisted that anonymity is a good thing, yet we’re all giving it up voluntarily. He wasn’t talking about the NSA or tech policy or anything like that. Rather, he said sites like 4chan may go the way of the dinosaur because people are choosing to join social networking sites and persistent identity services. One of the ‘Net’s greatest strengths is disappearing as a result, but moot claimed that sites like 4chan show that a lot of good can come of anonymity, too. He seemed puzzled as to why everyone wants their identity tied to so much of what they say and do online. Do people hold back? Do they censor themselves? The power of being able to say or post whatever you want is undeniably strong, but moot didn’t speak to the dangers of anonymity.

FINALLY; – (I found these two comments – to be accurate and insightful ~ From URL; http://www.news.com.au/technology/anonymous-hackers-threaten-to-shut-down-australian-government-websites-for-months/story-e6frfro0-1225829536342

Why do people keep saying it’s a child porn filter?? Conroy wants to censor sites like youtube for goodness sakes. it’s about banning anything and everything he doesn’t like not just child porn.

This just demonstrates how underprepared the government is to make sweeping changes to internet access. I predicted cyber attacks in response to the filter months ago, I can’t believe the government are so naive, and to now see them flailing around helpless against simple DDOS attacks is pathetic. This internet filter issue is waking a sleeping giant, DDOS is surely just the tip of the iceberg. The underground community have more resources and are more organised than what people give them credit for. How can they seriously complain about these attacks not being a legitimate form of political protest, when they are pushing this filter ahead without any public consultation in the first place? What goes around comes around.

GOOGLE – dns tools – and find lots more

THIS ARTICLE; (By Cricket Liu (Infoblox) [A Trusted Info Source]

Many Internet services count on DNS to return those “No such domain name” responses.  For example, mail servers often check to see whether the domain name used in an email address really exists to help decide whether the email is spam or not.  But NXDOMAIN redirection makes every domain name look like it exists.

It seems that google gears – (Or some other _wp-service is working now, as this link was ‘Automattically’ added,  as I pasted the paragraph above into this post) – is doing what it is supposed to do, .. (But – I dont like it because, I want to open in a new tabbed page – THIS belongs in the web-development section, with all the other rubbish)

Root Nameserver

Sunday, November 29th, 2009

FROM – URL: http://en.wikipedia.org/wiki/Root_nameserver

A root name server is a name server for the Domain Name System’s root zone. It directly answers requests for records in the root zone and answers other requests returning a list of the designated authoritative name servers for the appropriate top-level domain (TLD). The root name servers are a critical part of the Internet because they are the first step in translating (resolving) human readable host names into IP addresses that are used in communication between Internet hosts.

#2.2 http://www.isoc.org/briefings/020/

Q: Does all Internet traffic pass through the root name servers?
A: No Internet traffic passes through the root name servers at all. They have nothing to do with routing, note the difference in spelling. Name servers just answer queries from other parts of the DNS.

As described by OpenDNS Founder – David Ulevitch, on Jun 28th, 2006 – TOPIC – “Why he started OpenDNS” – (Pasted below)

DNS in two (or three) sentences
DNS is what allows you to type in a web address and end up at a website; DNS is transparent and yet fundamental to the operation of the Internet. There are two sides to DNS, the authoritative side which give out answers and the recursive side that ask questions on your behalf and holds onto them in case you ask again. OpenDNS provides the latter, the world’s first highly-available, high-performance recursive DNS service customized with features to make the Internet safer, faster and smarter for you.

The Micro$oft way – Home Premium, can NOT join a domain

Friday, November 13th, 2009

UPDATE; [Tuesday 26th January 2010] ~ Vista-Business WILL join a private-domain-based-LAN, .. IF you give it permission to update itself (IE, The Micro$oft-OS requires more-code from its maker)

You cannot join a Windows Vista Home Premium-based computer to a domain
This behavior is by design. (Thanks Mr Micro$oft) Vista-Business – Is NOT joining my domain – *WITHOUT* an ongoing stuggle (Much GOOGLING ~ and nashing of teeth)

Visit the Windows XP Solution Center

SYMPTOMS
If a computer is running Windows Vista Home Premium, you cannot join the computer to a domain.

CAUSE
This behavior occurs because Windows Vista Home Premium does not support a scenario where you join a computer to a domain.

Windows Vista Home Premium is designed as the foundation for a home entertainment system.

STATUS
This behavior is by design.

AND – (They politely tell me stuff like this [Below] – Must be hard being hugely successful like Micro$oft)

This article applies to a different version of Windows than the one you are using. Content in this article may not be relevant to you.

REFERENCE; [Installing Vista-Biz - Service-Packs 1 and 2 completed - AND; Vista-Biz still canNOT join a private domain - the ongoing mystery of Micro$oft securty continues]

DOMAIN NAMES – CONCEPTS AND FACILITIES

Saturday, November 7th, 2009

These two rfc written November 1987 – Obsoletes: RFCs 882, 883, 973 – QUESTION – Have these been updated – OR are they still the current rfc on the topic of ‘Domain Names‘ ?

http://tools.ietf.org/html/rfc1034

http://tools.ietf.org/html/rfc1035

A host can participate in the domain name system in a number of ways,

depending on whether the host runs programs that retrieve information from the domain system, name servers that answer queries from other hosts, or various combinations of both functions. The simplest, and perhaps most typical, configuration is shown below:

                 Local Host                        |  Foreign
                                                   |
    +---------+               +----------+         |  +--------+
    |         | user queries  |          |queries  |  |        |
    |  User   |-------------->|          |---------|->|Foreign |
    | Program |               | Resolver |         |  |  Name  |
    |         |<--------------|          |<--------|--| Server |
    |         | user responses|          |responses|  |        |
    +---------+               +----------+         |  +--------+
                                |     A            |
                cache additions |     | references |
                                V     |            |
                              +----------+         |
                              |  cache   |         |
                              +----------+         |
