#ARPANET

2026-03-02

Il 14 gennaio qualcuno ha staccato la spina a Telnet. Il traffico globale è crollato del 65% in un'ora, sei giorni prima che il mondo sapesse perché. Taiwan ha filtrato il 77%, l'India il 70%, il Giappone il 65%.

Un protocollo nato nel 1969, una vulnerabilità nascosta per 11 anni, 52 IP da 16 paesi che hanno tentato l'exploit, e un mistero che sembra un thriller. La storia completa nel nuovo episodio del buongiornirondirondello.

I'd previously been under the impression that the details of the #ARPANET IMP-to-IMP protocol (as opposed to the well documented #1822protocol for Host-to-IMP communications) had been lost, but it turns out that's not the case. In fact, it appears that in the last 15 years copies of multiple versions of the full source code for the #IMP software have been recovered by using OCR on hard copies. Much more information at walden-family.com/impcode/. I don't know the extent that the protocol itself has been reverse engineered from the code.

I love that this was written using #Midas, a programming language which was developed by a hospital. I think I did actually already know that, maybe from katiehafner.com/books-new/wher - presumably #BBN just used code they already had from an earlier consulting project.

Anyway - preserve your software projects. I'm sure many of the people doing this in the 60s and 70s didn't realise that what they were doing would be historically significant at the time.

TIL: #Dobrindt und Konsorten sind gar nicht so bekloppt, wie ihre Äußerungen zum Thema #kritis / #hackback vermuten lassen. Ihre EDV-Kenntnisse sind einfach nur auf dem Stand der frühen 70er, siehe de.wikipedia.org/wiki/Creeper_ – frei nach dem Motto
„Dieses #arpanet ist für uns alle Neuland“

You may have seen a "today in history"-type toot going around that talked about ARPAnet switching to the IP protocol, effectively being the birth of the internet. It was a long time ago.

And it made me realize that the internet per se was only 3 years old when I first experienced it.

Vor 43 Jahren: Wie TCP/IP aus ARPANET das Internet machte
Am 1. Januar 1983 startete ein Protokollwechsel, der das Fundament für das heutige Internet legte. ARPANET stellte schrittweise vom Network Control Program (NCP) auf TCP/IP um.

Happy birthday to the Internet!

On this day in 1983, the ARPANET network officially switched to using the TCP/IP protocol, effectively creating the Internet. usg.edu/galileo/skills/unit07/

CENI - La Chine vient de mettre en service l'héritier d'ARPANET

fed.brid.gy/r/https://korben.i

<p>Vous vous souvenez d'<strong>ARPANET</strong>, ce réseau militaire américain des années 60-70 qui a donné naissance à Internet ? En 2006, les États-Unis ont remis le couvert avec GENI, un autre réseau de recherche afin de tester les technologies futures du web et qui a fonctionné durant plus d'une décennie avant de s'éteindre progressivement jusqu'en 2023.</p>
<p>Et aujourd'hui, devinez qui vient de prendre le relais ?</p>
<p>La Chine, évidemment !</p>
<p>Le pays vient en effet d'annoncer la mise en service officielle de <strong>CENI</strong>, pour China Environment for Network Innovation, qui est ni plus ni moins que la première infrastructure nationale chinoise dédiée à l'innovation dans les technologies réseau. Et les specs font un peu peur je dois dire...</p>

</p>
<p>Il s'agit d'un réseau qui relie 40 villes chinoises via plus de 55 000 km de fibre optique et qui a nécessité plus de 10 ans de construction. Le truc est capable de supporter 128 réseaux hétérogènes simultanément et de mener 4 096 tests de services en parallèle... Niveau chiffres, c'est assez costaud.</p>
<p>Pour vous donner une idée de ce que ça peut faire, ils ont effectué un test de transfert avec le radiotélescope FAST dans la province du Guizhou. Résultat, 72 téraoctets de données transférées vers la province du Hubei en

@theonion Not the Pluribus I had in mind. #BBN #ARPANET

Das #ARPANet, der Vorgänger des #Internet, wurde mal entwickelt, um im Kriegsfalle einen kompletten #Systemausfall durch Ausfall von Teilsystemen zu verhindern. Das Routing setzt dann dynamisch andere Wege um, so dass das verbleibende Netz ungestört weiter machen kann.

Gestern musste ich sehr dringend noch einen
#Kickstarter, an dem ich teilgenommen habe, mit einem Eintrag im #Bakerkit finalisieren.

Auf beide Services konnte ich nicht zugreifen, weil eine kryptische Meldung des Services
#Cloudflare mir dies verweigerte.

"Das Internet" ist irgendwann total falsch abgebogen, als Services auf einmal alle zentralisiert wurden..
🙄

There's a mantra about the importance of redundancy that originated a long time ago in the military but applies in many contexts, including system and network administration.

"Two is one, and one is none." 🖥️ 🖥️

It's the design concept of the Internet itself—when it was still called "ARPANET". The idea was that in the event of a nuclear strike where a large part of the country was wiped off the face of the Earth, surviving systems and 'inter-networks' in other geographical regions would still be able to communicate with each other with little or no manual reconfiguration.

Resilience in the wake of failure was the goal, communication was to be ensured at all costs.

RAID, failover WAN, BGP (and TCP/IP routing in general), server clustering all mitigate downtime in the event of failure of a single component (or even scheduled maintenance where pieces must be taken offline).

It's a practice that I won't say I'm *obsessed* over, but I absolutely enjoy employing it wherever I can, even if it seems overkill. ✅ 💙 😎 Call it my inner-prepper, I dunno 😂

On in 1969, , a US military project and the precursor the , established the first successful host-to-host link between computers. A pioneer in packet switching networks, ARPANET made possible the interconnected world we all now share.

The actual first message that was sent that day was just "LO", first two letters of the word "LOGIN", when the system crashed.

A portion of an interview from the linked website:

Did you realise this could be a historic moment?

Kline: No, I certainly didn't at that time.

Duvall: Not really. It was another step forward in the larger context of the work we were doing at SRI which we did believe would have a large impact.

When Samuel Morse sent the first telegraph message in 1844, he had an eye for drama, tapping out "What hath God wrought" on a line from Washington, DC to Baltimore, Maryland, US. If you could go back, would you have typed something more memorable?

Kline: Of course, if I had realised its importance. But we were just trying to get it to work.

On this day, 56 years ago:

"At 10:30 p.m., 29 October 1969, the first ARPANET message was sent from this UCLA site to the Stanford Research Institute."

A black commemorative plaque with gold frame, inscribed with gold letters. It reads:

"At 10:30 p.m., 29 October 1969, the first ARPANET message was sent from this UCLA site to the Stanford Research Institute. Based on packet switching and dynamic resource allocation, the sharing of information digitally from this first node of ARPANET launched the Internet revolution."
