@revk@toot.me.uk @Dragon@toast.dragon2611.net @neil@mastodon.neilzone.co.uk Back when I was at university, I fired up dhcpd on the computer society's firewall to serve their internal network and then went to my morning lectures. Turns out the dhcpd man page was a bit wrong and when I configured it to not hand out leases on the external NIC, it sent refusals instead. Turns out it sent refusals faster than the uni's real DHCP server could respond and took out the entire uni network. Back in those days it was a more-or-less flat /16 across the site.

@steve@mastodon.nexusuk.org @revk@toot.me.uk @Dragon@toast.dragon2611.net @neil@mastodon.neilzone.co.uk oh, are we doing DHCP/university network war stories? 😀😀

So, back before wifi was a thing, we'd have a few thousand freshers turn up each year with PCs with no NIC in them, wanting to connect to them to the halls of residence network.

The local bricks and mortar computer shop would happily sell them cheap chinese NE2000 clones. Except this one year they'd got
really cheap ones, that all had the same MAC address 😳😳😂😂
