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

[–] Mr_Dr_Oink 3 points 18 hours ago

omg! A rollercoaster tycoon reference in the wild!

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

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

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

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"

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

[–] [email protected] 7 points 1 day ago

That would be a great way to piss off the school

Is this what they call the loopback interface?

[–] [email protected] 10 points 1 day ago

Yeah pretty much

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

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

Please leave some internet for the rest of us!

Squeezing the last bit of internet out of the cloud

[–] [email protected] 32 points 1 day 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!

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 19 points 1 day ago* (last edited 1 day 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.

[–] [email protected] 19 points 1 day ago (1 children)

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

[–] [email protected] 36 points 1 day 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 10 points 1 day ago

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

[–] takeda 6 points 1 day 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.

[–] [email protected] 2 points 1 day ago (1 children)

You just connect your laptop and run a broadcast ping

Problem solved

[–] takeda 1 points 22 hours ago

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

[–] [email protected] 14 points 1 day ago (2 children)

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

[–] [email protected] 4 points 1 day 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.

This is how Scotty survived being trapped in that Dyson Sphere for all that time..

Ah broadcast storms. The best kind of storms.

[–] WIPocket 15 points 1 day ago (1 children)

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

[–] mvirts 4 points 1 day ago

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

[–] [email protected] 4 points 1 day ago

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

Yes I do have kids why do you ask?
