Nabto Client Wrapper for Python

python-nabto-client

Python Wrapper for the Linux and macOS native Nabto Client SDKs.

Requirements

• Python 3.6+
• python3-dev package for Debian distributions
• Linux or macOS (Windows is not supported - let us know if you need this!)

Installation

Install using pip...

pip install -i https://test.pypi.org/simple/ nabto-client

Example

Let's take a look at a quick example of using nabto_client to open a session and a tunnel.

import nabto_client

NABTO_HOME_DIRECTORY = "/home/nabto/example"

USER = "user"
PASSWORD = "password"

LOCAL_PORT = 7000
NABTO_HOST = "example.appmyproduct.com"
REMOTE_HOST = "localhost"
REMOTE_PORT = 8000

# Initializes the Nabto client API
nabto_client.startup(NABTO_HOME_DIRECTORY)

# Creates a Nabto self signed profile
nabto_client.createSelfSignedProfile(USER, PASSWORD)

with nabto_client.NabtoSession(USER, PASSWORD) as session:
    with nabto_client.NabtoTunnel(session, LOCAL_PORT, NABTO_HOST, REMOTE_HOST, REMOTE_PORT) as port:
        print(f'Opened tunnel on port {port}')
        ...

# Releases any resources held by the Nabto client API
nabto_client.shutdown()

Tunnel status

The example above doesn't allow to query the current status of the tunnel because the context manager returns the port not the tunnel object.

If you want to query the tunnel status, don't use the context manager, instead create and open a tunnel like this:

tunnel = nabto_client.NabtoTunnel(session, LOCAL_PORT, NABTO_HOST, REMOTE_HOST, REMOTE_PORT)
print(f'Tunnel status is {tunnel.status()}') # -1 or TunnelStatus.CLOSED
port = tunnel.openTcp()
print(f'Opened tunnel on port {port}')
print(f'Tunnel status is {tunnel.status()}') # 3 or TunnelStatus.LOCAL
# ... do something with the tunnel
tunnel.close()
if nabto_client.TunnelStatus.CLOSED == tunnel.status():
    print(f'Tunnel is closed')

You can also run example/cli.py for an interactive example.

python example/cli.py --device example.appmyproduct.com
