The packets: "I want to get off Mr Bones' wild ride"

[–] Mr_Dr_Oink@lemmy.world 3 points 2 days ago

omg! A rollercoaster tycoon reference in the wild!

You have to first capture the internet in the loop, and then it just travels around in the router forever.

[–] rbn@sopuli.xyz 21 points 2 days ago (1 children)

Please leave some internet for the rest of us!

Squeezing the last bit of internet out of the cloud

Would the switch do anything here? Wouldn't there need to be something else plugged in? Like a laptop or pc?

[–] qprimed@lemmy.ml 32 points 2 days ago (1 children)

you (yes, you in particular) are the reason why STP was invented.

I would normally suggest that this is more "networking porn", but its just way too fetishistic for regular consumption. you animal!

Would be a shame if someone plugged this into a school network :)

[–] possiblylinux127@lemmy.zip 7 points 2 days ago

That would be a great way to piss off the school

[–] problembasedperson@lemmy.dbzer0.com 13 points 2 days ago (1 children)

Is this what they call the loopback interface?

[–] possiblylinux127@lemmy.zip 10 points 2 days ago

Yeah pretty much

127.0.0.1->127.0.0.2....... 127.0.0.254-> 127.0.0.1

I love that you can plug a switch into itself that essentially causes a data short circuit of the switch talking to itself without realising it.

[–] friend_of_satan@lemmy.world 19 points 2 days ago* (last edited 2 days ago)

Unless the switch has STP enabled.

The Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Ethernet networks.

[–] 0ops@lemm.ee 19 points 2 days ago (1 children)

Why is the switch talking to itself? Is it stupid??

[–] possiblylinux127@lemmy.zip 36 points 2 days ago (2 children)

Switches are kind of stupid from a hardware perspective. A basic switch just has a lookup table that has all the connected devices and if it can't find the destination address in the switch sends it out on all ports. There are protocols to handle this but they add overhead and are only available on higher end devices.

You can imagine what kind of chaos this could cause

[–] SpaceNoodle@lemmy.world 10 points 2 days ago

No need to imagine, I've done it myself!

[–] takeda@lemmy.world 6 points 2 days ago (1 children)

I'm still puzzled though. Is switch initiative the ARP request? I though that since nothing (that can communicate) is connected to it except itself, it would be just quiet.

[–] possiblylinux127@lemmy.zip 2 points 2 days ago (1 children)

You just connect your laptop and run a broadcast ping

Problem solved

[–] takeda@lemmy.world 1 points 2 days ago

I see, so that's how you bootstrapped it?

[–] bearded_zero@lemmy.world 5 points 2 days ago* (last edited 2 days ago)

This is knot funny. Someone needs to ping the mods!

[–] HK65@sopuli.xyz 14 points 2 days ago (2 children)

Wouldn't something like spanning-tree just down all ports on this?

[–] Sailing7@lemmy.ml 7 points 2 days ago
[–] TechGuy@discuss.online 4 points 2 days ago

If it’s present, and loop guard is enabled, it would block the ports. This looks like an unmanaged switch so probably doesn’t have that feature.

Most of Netgear’s managed switch range have a loop guard function, even if they don’t do full STP.

It’s a Euthanasia Coaster where the cars are 802.3 frames.

[–] possiblylinux127@lemmy.zip 3 points 1 day ago

John Allen, who served as president of the Philadelphia Toboggan Company, inspired Urbonas with his description of the "ultimate" roller coaster as one that "sends out 24 people and they all come back dead"

[–] slazer2au@lemmy.world 5 points 2 days ago

Ah broadcast storms. The best kind of storms.

[–] mvirts@lemmy.world 5 points 2 days ago (1 children)
[–] WIPocket@lemmy.world 15 points 2 days ago (1 children)

It doesnt even matter, TTL is only decreased when routing. Ethernet frames have no such concept.

[–] mvirts@lemmy.world 4 points 2 days ago

Til. I thought switches would decrement ttl but that makes perfect sense.

The post title adds so much I laughed mostly because of it.

Yes I do have kids why do you ask?
