Go library to handle tens of thousands SSH connections and execute the command(s) with higher-level API for building network device / server automation. Documentation and examples are available via godoc.
- Connect to multiple remote machines concurrently
- Persistent SSH connection
- DSL query based on the labels
- Manage number of sessions per SSH connection
- Limit amount of stdout and stderr data in bytes
- Higher-level API for building automation
