A lightweight, ergonomic SSH library.

EZSSH

An Ergonomic and Lightweight SSH Library.

Installation

pip install ezssh

Quick Start

from ezssh import SSHRunner, Command, BatchPolicy

# As of v0.0.9, SSHRunner will auto-add on new host. Disable for added security.
with SSHRunner(
    host="10.0.0.5",
    username="ubuntu",
    password="secret", # password as null will attempt pubkey
    missing_host_key_policy='autoadd'
) as runner:

    result = runner.run("uname -a")
    print(result.stdout)

    batch = runner.run_batch(
        [
            "whoami",
            Command("systemctl is-active ssh", sudo=True, name="ssh_status"),
        ],
        policy=BatchPolicy(stop_on_failure=False),
    )

    for r in batch.results:
        print(r.command.name, r.exit_status)

Batch Operations

batch processing of cli commands is also available. To execute a chain of prepared commands:

batch = runner.run_batch(
    [
        Command("mkdir -p /tmp/example"),
        Command("touch /tmp/example/file.txt"),
        Command("false", name="intentional_failure"),
        Command("echo still runs"),
    ],
    policy=BatchPolicy(stop_on_failure=False),
)
# Each returns an exit status, stdout/stderror, start/end and duration.

Authentication Behavior

Password auth uses password only, agent and key discovery are opt-in.

SSHRunner(
    host="example.com",
    username="user",
    password="secret",
    allow_agent=False,
    look_for_keys=False,
)

When to Use ezssh

Use ezssh if you need:

• Programmatic SSH execution embedded in a Python application
• Deterministic batch execution with structured results
• Explicit authentication behavior
• Lightweight automation without orchestration frameworks

Do not use ezssh if you need:

• Configuration management
• Long-lived agents
• Inventory management
• Declarative state convergence
