Technical Details

what runs on :3301

Tarantool's native binary protocol, commonly called iproto, runs over TCP and uses MessagePack-encoded request and response headers and bodies. A connection begins with a server greeting, after which clients exchange framed requests identified by synchronization IDs; authentication can use a challenge-response exchange. TLS is supported in suitable deployments but is not enabled by default, so ordinary port 3301 traffic is typically cleartext.

security overview

An exposed Tarantool listener may provide database reads and writes, administrative operations, or application-specific functionality depending on configuration and credentials. It should generally be restricted to trusted application and cluster networks, especially because authentication and TLS are deployment-dependent; IANA also reports unauthorized use of this assignment.
