Zero-Netcat

Netcat style utility using ZeroMQ sockets

• Free software: MIT license

Features

• Simple command line ZeroMQ sockets for use in shell scripts and other CLI stuff

Installation

python setup.py install

Usage

Usage

zeronc [-h] [--io-threads IO_THREADS] [--ipv6] [--send-hwm SEND_HWM]
           [--receive-hwm RECEIVE_HWM] [--subscribe SUBSCRIBE]
           [--topic TOPIC] [--buffer-size BUFFER_SIZE] [--output OUTPUT]
           address [address ...]

• io-threads refers to the number of IO threads to allocate to ZeroMQ
• ipv6 enables ipv6 addressing in addition to ipv4
• send-hwm is the number of bytes to be queued before discarding or blocking outgoing messages
• receive-hwm is the number of bytes to be queued before discarding or blocking incoming messages
• subscribe (for SUB sockets) subscribes to a given topic - default is to subscribe to all messages, can be used multiple times
• topic (for PUB sockets) the topic to send messages on (default is default_topic)
• buffer-size is the buffer size to use for incoming reads
• output specifies the file name to write output, default is standard out

address refers to a triple in the format <bind | connect> <socket type> <address>

multiple address of the same direction can be provided (reading or writing)

When multiple addresses are provided, incoming data will be fair queued between address (PUSH-PULL) and outgoing data will be broadcast to all addresses (PUB-SUB)

For example: bind sub tcp://127.1:5001 binds a SUB socket to port 5001

Available socket types are PUB / PUSH in writing mode, and SUB / PULL for read

TODO

This was a quick weekend project. Could use some more thorough testing and some friendliness with slow stdout consumers.
