The PTR record enumeration trick is often fun to try on hotel and other public networks.

The problem here is that many places segment their guest network away from the internal one, but they use the same DNS server for both, so guests can still resolve internal hostnames and perform rev DNS queries.

I usually like to run a traceroute or two (to some arbitrary external IP like 1.1.1.1 or 8.8.8.8) whenever I connect to a new network. As traceroute does rev dns by default, if you see the internal hostname for your default gateway (and possibly other hosts inbetween you and the wider internet), those IPs are likely good starting points for your rev DNS shenanigans.

Wow. No police, no handcuffs, no lawyers... Just a polite request.

This must be happening in some alternate universe.

I've did plenty of shit stuff in school, always got polite requests to stop rather than getting the police called on me, except one time.

I think "kid did a hacking, adults called the cops" is less common than people think, it just doesn't usually make the news when that happens, only when the cops get involved the media get involved, so essentially survivor bias.

Exactly, if it wasn't extraordinary it wouldn't make the news. The problem is when people think what's reported as news is normal rather than exceptional.

Even running a port scanner is enough to face disciplinary action at many US colleges. Taking down the network for the entire school for 15 minutes surely deserved more consequences than were doled out here. I'd encourage the author to focus their efforts and talents on something more constructive.

Happened to me too. Back in the early 2000s, my college had two outbound Internet connections. One was shared with all students and one was shared with all labs/classrooms/etc. Connecting from dorms to labs was quick, and labs to internet quick, but dorms to internet was slow as molasses especially at certain times of day when a ton of students were on the Internet.

So I found some always on lab machine and ran squid on it, so I could get on the Internet through the labs from my dorm.

Turns out some tech found it after a few months, and tried to kill it but ended up fork bombing the system. And it fork bombed again whenever they rebooted it. That system apparently was the one used for scheduling anything at the college and they weren't happy with it going down.

At like 8am one day 3 techies knocked on my door and were like "uhhh..please don't run squid any more" and that was that.

It was a glorious 3 months though when I was getting 1mb/s downloads and everyone else around me was getting 75kb/s

At colleges that I've worked at it really seems to depend on intent. If you fuck up the network trying to increase your own speeds, warning. If you maliciously try to access protected information, cops.
