Could you build this into a protocol?
Like an ssh setting that only allows incoming connections that can prove (well, suggest) their proximity by a series of latency tests?
- dataflow 5y agoI think DRM would be a much better use case than security (SSH).
- betaby 5y agoYou can set a TTL limit in the kernel. Close enough to a latency limit.
- MertsA 5y agoThat's actually used for neighbor discovery on IPv6 to unconditionally limit it to unrouted packets.
- fanf2 5y agoTTL checks are sometimes used by mobile providers to try to prevent tethering.
- convolvatron 5y agothat is so foul
- netflixandkill 5y agoThere's no reason you couldn't, but distance is not the only source of latency, so you're unlikely to find an existing case of someone doing that intentionally. Easy enough to whitelist geo-ip matches or large net block ranges for a similar result.
- rtkwe 5y agoYou could but it's much easier to get servers in a near-by area with AWS and other easy virtual hosting providers.
