TCP

The Transmission Control Protocol (TCP) provides a bidirectional byte stream over IP. Tenzir provides operators for both sides of a TCP conversation: connecting to remote endpoints, accepting incoming connections, and serving data to connected clients.

Use the IP address 0.0.0.0 to listen on all available network interfaces.

URL support

The URL schemes tcp:// and tcps:// dispatch to load_tcp and save_tcp for seamless URL-style use via from and to.

Connecting to remote endpoints

Use from_tcp to connect to a remote TCP endpoint as a client and read data from it, or to_tcp to send data to a remote endpoint. Both operators reconnect automatically with exponential backoff on connection failure.

Accepting incoming connections

Use accept_tcp to listen on a local endpoint and accept incoming TCP connections. Each connection spawns a nested pipeline that processes the incoming byte stream independently.

Serving data to clients

Use serve_tcp to start a TCP server that broadcasts pipeline output to all connected clients. A nested pipeline serializes events into bytes before sending.

See Get data from the network for practical examples.

SSL/TLS

All TCP operators support TLS via the tls option. Pass an empty record (tls={}) for defaults, or provide specific options like certfile and keyfile. like certfile and keyfile.
