I feel like you have to be brave messing with a plane's network. People tend to get really touchy when airplanes are involved.

I was going to say this too. I once merely mentioned the words “Heart Attack” on a plane and was kicked off by the flight attendants. No context, they just heard the words and forced me off. There are things that trigger them because of laws and regulations like mentioning “bomb” (even if you’re describing something fantastic). So messing with the gogo flight entertainment is up there with flirting with terrorism cha…

I do not buy this.

I was on airplane with large aggressive dog, that was harassing other passengers. I was worried it would ampute my limb mid flight.

I voluntary left before take off, dog stayed!

If you move to an empty seat to prevent WiFi signal strength triangulation, and assuming the cabin has no cameras, you didn't auth to the network with identifiable information, actually encrypt your Xray proxy connection (which OP didn't), and you have MAC randomization on, there's next to no way the airliner would be able (or even care) to identify that you did what was described in the article. Sure, they could use DPI and behavioral analysis to detect you were misusing the network, but if they're doing that, they would just block this sort of "backdoor" from the get-go.

I'll echo the article's disclaimer: This reply is intended solely for educational and research purposes. I affirm the strict adherence to all relevant regulations and service terms.

I agree, this sounds a bit too stretched. Or maybe they were looking for any excuse under the sun to get someone off what could have been an overbooked flight. But just saying the two words "heart attack" would not be enough

If a ping to a specific IP times out, I wouldn't say the IP is blocked. It could be that ICMP specifically is blocked, following some network rules on the firewall. This is pretty common in entreprise networks to not allow endpoint discovery. I could be missing something and happy to be corrected here, but I was surprised to read that.

I find it's important to remember, too, that a failed PING tells you nothing other than your echo request did not receive a response. If the remote host received your request, and if it responded, are both things a failed PING can't tell you, because both of those things could be true but you still end up with a failed PING. I've seen technicians get tripped up in troubleshooting thinking that a failed PING tells the…

And that can be a lot more subtle than you might think. I've had a persistent very hard to debug false alarm triggered on pings sometimes not making it and most of the time they did. But very rarely that would happen three times in a row and that was the threshold for raising an alarm. We spent days on this. Finally, the root cause was tracked down to a BNC 'T' connector at the back of a media adapter that filtered out the header of some percentage of ICMP packets. It is one of the weirdest IT problems I've ever encountered and it makes me wonder how much of what we rely on is actually marginal.

Could y'all point at instructions for how to imitate this limited internet situation ?

I ask because, two years ago, I was able to circumvent the Windows-11-requires-internet-and-a-microsoft-account part of the set up for a new laptop computer by doing this on a flight. Apparently, connecting to the airplane wifi (without yet logging in) was enough to satisfy the OS set-up, but limited enough that my laptop didn't require a microsoft account. With windows 10 now end of life, I will probably get a new desktop computer and would like to repeat the feat at home. Thanks

Set up a wifi network with no internet? If you have a separate router/modem, just unplug your modem from your router. If your mode/router is combined unplug the coax/fiber/phone line.

Yeah I am a bit confused about posts like this. It’s bragging about breaking the law. There was a particularly bad one a few months ago where a kid had hacked Monster’s employee training site, and was sharing all this internal media in the post. I don’t understand how they don’t end up getting in some seriously annoying trouble with law enforcement. Well I looked it up just now and the post was deleted, I guess maybe…

> breaking the law Not law per se. More like contractual obligations taken upon by connecting to the flight's WiFi.

Isn't this pretty straightforwardly "theft of service", like "stealing" cable TV service?

I highly doubt any airline staff are on your flight (or even remotely) counter-hacking one in a billion passengers messing around with the in-flight WiFi. That $30.75 they're not getting doesn't justify anyone looking into it.

Why does Air Canada charges $30 for internet, that's brutal. Especially on 12hr flight where it should be provided for free imo.

>Especially on 12hr flight where it should be provided for free imo.

"Should" in the sense that "everyone should get free food, housing, and healthcare" or that other airlines actually provide it for free? I don't know of any airline that provides it for free, the most is some Asian/Gulf airlines providing "free for 1 hour" or similar. Compared to that, "free texting, unlimited" doesn't seem too bad, considering there are also trans-continental flights with no internet access at all.
