Technical Details

what runs on :2433

Coda client/server filesystem RPC can use both TCP and UDP, with port 2433 assigned to the secure server endpoint. It is distinct from port 2432, the ordinary Coda server service; Coda's secure mode provides authenticated, protected protocol communication rather than a conventional TLS service.

security overview

This port should normally be reachable only by trusted Coda clients and infrastructure, not exposed to the public internet. Internet exposure can disclose or make a legacy distributed-filesystem service available for probing and implementation-specific attacks, although current deployments are uncommon.
