Ping 127.0.0.1

January 21, 2010

Ping 127.0.0.1 – The system internal-loopback adapter, confirms the TCP/IP-stack is loaded.

Fix / Text ADSL Connectivity ~ Use TCP/IP utilities

#1: ipconfig /all ~ “interrogates network adapters” – This will tell you about the network-adapters installed, and protocols information. – Help determine details about your ISP connection. And, the first-error to look for = ‘Media-disconnected!’ – No Physical connection to the outside world.

SOLUTION: Check the phone line, cable or Ethernet cable is plugged in, .. (Unplug and and ‘reconnect’ etc)

#2: If there is no IP address listed, .. Determine if TCP/IP is working, this is completed by pinging the systems internal loop-back address / adapter with ‘ping 127.0.0.1’. Receiving a reply, confirms the TCP/IP stack is loaded, but a destination host unreachable error means TCP/IP has gone AWOL.

#3: Once you know TCP/IP is working, ensure your own adapter is talking to it. Ping your own IP address.


no valid boot disk

PCI primarily a 32-bit bus system – found this comment interesting in context of 64-Bit systems.

[From section 2.1 QUOTE - "Note that eventhough there is a 64-bit PCI bus, it's not natively supported, since PCI uses a dual address cycle to implement it. So, we can say that PCI primarily a 32-bit bus system."]

DOMAIN NAMES – CONCEPTS AND FACILITIES

November 7, 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   |         |

Bits per second

November 7, 2009

Units of Measurement
bit= smallest unit of digital information, i.e. ones & zeros
byte= a set of bits
bps= bits per second
Kbps= kilobits per second =1000 bits per second
Mbps = Million bits per second =1,000,000 bits per second
Gbps = Gigabits per second = 1,000,000,000 (one billion) bits per second
Tbps = Terabits per second = 1,000,000,000,000 (one trillion) bits per second

The Internet's three virtues

November 2, 2009

POINT – 8. The Internet’s three virtues

http://www.worldofends.com/

Taken from; ‘World of Ends’ – What the Internet Is
by Doc Searls and David Weinberger

In a Nutshell – The Nutshell -

1. The Internet isn’t complicated
2. The Internet isn’t a thing. It’s an agreement.
3. The Internet is stupid.
4. Adding value to the Internet lowers its value.
5. All the Internet’s value grows on its edges.
6. Money moves to the suburbs.
7. The end of the world? Nah, the world of ends.
8. The Internet’s three virtues:
a. No one owns it
b. Everyone can use it
c. Anyone can improve it
9. If the Internet is so simple, why have so many been so boneheaded about it?
10. Some mistakes we can stop making already

For those without the TIME – READ; Scroll-Down and Read (Especially Point 8, 8a, 8b, 8c)

INTERESTING POINTS:
“The Internet interprets censorship as damage and routes around it,”

POINT – 8. The Internet’s three virtues
(I have ‘Re-Worded’ this just a little for my own interpretation)

8.a Nobody owns it
It can’t be owned, even by the companies whose “pipes” it passes through, because it is an agreement, not a thing. The Internet not only is in the public domain, it is a public domain.

8.b Everyone can use it
The Internet was built to include everyone on the planet.
You don’t need a system administrator to let you participate. The Internet purposefully leaves permissions out of the system.

8.c Anybody can improve it
Anyone can make the Internet a better place to live, work and raise up kids. It takes a real blockhead with a will of iron to make it worse.
In the same way the agreement about how to encode images on paper enabled fax machines to use telephone lines without requiring any changes to the phone system itself.
The creators of these services (email and newsgroups) didn’t simply come up with end-based applications, and they sure didn’t tinker with the Internet protocol itself.


net-neutrality

November 2, 2009

net-neutrality; TAGED under ‘GNU License’ (My perspective – nobody owns the Internet -and nobody should own it – especially big business that already make HUGE profits) – OBVIOUSLY; It is more complicated than that, .. (As usual, – the more I dig around, the more complicated this gets, and the fuzzy-bits intrude) – [MORE fuzzy-bits]

THIS EXPLIANS (In part) >>> Best video yet on Net Neutrality <<<

THE FCC (and what role they play?)
The Second Computer Inquiry is the second proceeding in the FCC trilogy The Computer Inquiries, which created the FCC’s policy of regulating the way in which telecommunications carriers’ networks are opened up and made available to enhanced services (aka computer networks).

Some background information on this topic; As I have often questioned, (As an interested observer) ‘Is the Internet already tiered?’ – Meaning; Should carriers be able to sell multi-tiered access to heavy users? OR; They are already doing this!

From the laymans point of view – It already IS multi-tiered, for those prepared to PAY-MORE, they get a FASTER connection.

THIS-DEBATE; ‘Net Neutrality’ – is MORE about the users ability to upload their own content, and THAT RIGHT is under threat from the like of big telco companies (AT&T verizon, and Cablevision) wanting to take away that ability, and turn the Internet into a ‘One-directional-medium’, more LIKE radio and TV.

PASTED BELOW; Is an outline from opposingviews.com – which points to ‘summer-2005′, as being [QUOTE] “The separation of the physical communications layer from the content and applications layers was a cornerstone of telecommunications law–putting control of the Internet in the hands of the users at the edges

[THE IMPORTANT BIT - QUOTE Cont'd] , .. “but in the summer of 2005 — under intense pressure from phone and cable lobbyists — the FCC removed this cornerstone.”

ARTICLE; Net Neutrality is the Internet’s First Amendment
Save the Internet (Most of it pasted below – but not all)

Almost 40 years ago, the Federal Communications Commission was confronted with the question of how to handle the transmission of data over telecommunications networks. When a federal court broke up Ma Bell in 1982, it required the Baby Bells to provide nondiscriminatory interconnection and access to their networks. These decisions to require the communications network to treat information service in a nondiscriminatory manner was the key building block of the Internet — it’s First Amendment.

Under these protections, the physical wires over which data and information flow were treated differently than the data and information themselves. When network owners can’t mess with the content, the content market remains free and vigorously competitive. This separation of the physical communications layer from the content and applications layers was a cornerstone of telecommunications law–putting control of the Internet in the hands of the users at the edges but in the summer of 2005 — under intense pressure from phone and cable lobbyists — the FCC removed this cornerstone.

In the years since then, these network owners have openly declared that they intend to build business models based on discrimination, extorting money from online content and applications providers and favoring the Web sites and services that they own or with whom they strike special deals. This plan violates the fundamental principle of nondiscrimination that has been law for generations, and which gave us a free-flowing Internet that allows the best ideas to emerge on their own merits.

From a technical prepective; http://www.worldofends.com/  (A nice simple approach to the Internet)

Advocates of Net Neutrality are not promoting new regulations. We are attempting to restore tried and tested consumer protections and network operating principles that made the Internet a great engine for free speech and innovation. By passing Net Neutrality legislation we’re restoring under law the open Internet’s most fundamental principle.


Internet – 40 years old

November 1, 2009

ARTICLE – Happy 40th Birthday, Internet! – By Jared Newman

On October 29, 1969, the Internet came in not with a bang, but with a “lo.”

The Internet was born with the first data message sent between two networked computers.

RE – DISCOVERED: (URL; pcworld.com) – AND; Found a recent update to a favourite topic of mine (One that spells it out in simple terms for the average user) The article – the ongoing  debate on, .. >>>  ‘Net Neutrality FAQ: What’s in it for You’ <<<

This topic/debate is VERY-linked into the Mis-Guided filter systems, that various governments continue to impose on Interlinked-Networks
