Python Telnet Utility: asyncio-powered

The asyncio-telnet library designed for convenient interaction with Telnet devices in both synchronous and asynchronous modes, making the process straightforward and flexible in various usage scenarios.

• Support for Asynchrony and Synchrony: Harness the power of asyncio for efficient and non-blocking communication with Telnet servers. With this library, you have the option to choose between asynchronous and synchronous modes, depending on the requirements of your project.
• Ease of Use: The library provides a user-friendly interface for both synchronous and asynchronous cases, making it adaptable to different project needs.
• Telnet Protocol Handling: Transparently handles the intricacies of the Telnet protocol, allowing you to focus on the logic of your application.
• Flexible Integration: Easily integrate Telnet functionality into your Python applications with a simple API.

Installation

You can install the library using pip. Make sure you have Python 3.6 or later installed.

pip install asyncio-telnet

Usage

Example: Asynchronous Telnet Connection with Default Timeout

import asyncio
from asyncio_telnet import Telnet

async def main():
    tn = Telnet()
    await tn.open('example.com')
    await tn.write(b'Vladimir\r\n')
    response = await tn.read_until_eof()
    await tn.close()
    return response

if __name__ == '__main__':
    result = asyncio.run(main())
    print(result)


# Example of successful execution:
# b'\n***************** User Access Login ********************\r\n\r\nUser:'

Example: Synchronous Telnet Connection

from asyncio_telnet import Telnet

def main():
    tn = Telnet(sync_mode=True)
    tn.open('example.com')
    response = tn.read_until_eof()
    tn.close()
    return response

if __name__ == '__main__':
    result = main()
    print(result)


# Example of successful execution:
# b'\n***************** User Access Login ********************\r\n\r\nUser:'

Example: Asynchronous Telnet Connection with Custom Timeout.

By default, the timeout is set to 30 seconds.

import asyncio
from asyncio_telnet import Telnet

async def main():
    tn = Telnet(timeout=5)
    try:
        await tn.open('example.com')
        response = await tn.read_until_eof()
        await tn.close()
        return response
    except ValueError as e:
        print(f"Example of a timeout occurrence: {e}")

if __name__ == '__main__':
    asyncio.run(main())


# Example response:
# Example of a timeout occurrence: Timeout connecting to example.com:23

Example: Asynchronous Telnet Connection with Write Operation

import asyncio
from asyncio_telnet import Telnet

async def main():
    tn = Telnet()
    await tn.open('example.com')
    await tn.write(b'Vladimir\r\n')
    response = await tn.read_until_eof()
    await tn.close()
    return response

if __name__ == '__main__':
    result = asyncio.run(main())
    print(result)


# Example of successful execution:
# b'\n***************** User Access Login ********************\r\n\r\nUser:Vladimir\r\nPassword:'
