can-hub

CAN bus over the network, done right. Devices behind NAT export their SocketCAN interfaces to a central hub over QUIC with mutual TLS; clients anywhere consume them with the tools they already use.

• Works through NAT and firewalls — agents and clients dial out; the hub rendezvous in the middle.
• Zero-config security — identities generated on first start, pinned on first use, mutual TLS, per-interface read/write ACLs.
• The right transport for CAN — control on reliable streams, frames on latest-wins datagrams.
• Your tools, unmodified — mirror a remote bus into a local vcan, or keep using socketcand clients through the bridge.
