Tech:Online?

19 Mar 2020, by from Tech

Da ble TG avlyst i disse COVID-19-tider. Nok er sagt om det, men mye var alt satt i bevegelse. Mange arbeidsdager er lagt ned i det.

Og vi (TG-crewet) prøver å stable på bena et alternativt arrangement i hurten og sturten, TG:Online. Hva dette vil være vet vi ikke helt enda, men det er uansett klart at Tech sin rolle vil være svært begrenset når vi ikke lenger skal levere nettverk og internett til 5000 mennesker.

Så jeg begynte å lure litt på hva vi kan gjøre?

En av tankene jeg har hatt er at vi har en masse nettverksutstyr vi ikke får brukt til noe. Jeg hadde selv behov for å labbe, så tok med meg litt stash hjem og så hva jeg fikk til.

Stue-lab, med “kant”, “distro” og “core”.

Så jeg leker litt med tanken på om vi klarer å levere noe sånt for flere? Vi har jo et tredvetalls konsoll-kabler og masse skjermer og NUCer på lager.

Man kan labbe virtuelt, men det har bare ikke den samme “feelingen” som fysisk utstyr har.

Hva om vi setter opp noe ala riggen på bildet, smeller konsoll-kabler på alt og lager en slags “capture the flag”-konkurranse der folk får mulighet til å konfe utstyret så pc’er kommer på nett? For å gjøre det litt gøy smeller vi på noe skjermer som “pinger” internett og litt sånt, med et webcam man kan følge med på? Gudene vet, men det høres gøy ut å prøve.

Aner ikke om det lar seg gjøre, men i mellomtiden labber jeg videre. Bli gjerne med i diskusjonen på TG sin Discord (#tech-kanalen) om dette er interessant!

We’re here!

Just wanted to let you all know that The Gathering Tech crew is actually here working.

Tech is thinking
After working for almost two full days, some tasks require more thought than others.

Fun facts

Some fun facts from us…

Link up/down

Our D-Link access switches have logged 133,184 link up-events and 128,996 link down-events.

Some switches have more events than others Some switches have more link up-events than others (x-axis is switches, y-axis is count)

This may be reboots, cables unplugged and plugged back in, eventual power outages and other things.

Access lists

Our access lists have protected the D-Link access switches against 25,670 connection attempts. This is probably random port scans.

nocgw-temp

There is an obvious glitch Wednesday night…
This shows temperature from both inlets and outlets as well as some chips!

Lowest temperature reported from nocgw is 15 degrees Celsius. No wonder we were freezing 🙂

Spanning tree

Spanning tree on the D-Link switches have blocked 11 loops.

Wireless

We have a wireless network in addition to the wired.
There are access points through the ship, so coverage should be good. Due to a large amount of devices, “rogue” networks and normal interference we recommend using 802.11a for best performance!

The network is not encrypted and the SSID is broadcasting as “TG12-WLAN”.

By the way, if you see one of these blinking – think of us. (One of our crewmembers wrote disco.pl to make them blink – and we might use it when we’re bored!)

Network design

Some of you have asked for a look at this years network design…

I’ve just updated our drawings: This is the current (and working) design for our main network.

TG12-design

All participants are connected to either CoreNGW or CoreSGW via D-Link DGS-3100-48 switches.

(Update: I forgot some changes earlier 🙂
