Get file’s creation timestamp using Paramiko SFTP

by

What You Will Learn

In this tutorial, you will master the technique of retrieving a file’s creation timestamp using Paramiko SFTP in Python. This skill is essential for managing and analyzing file metadata efficiently.

Introduction to the Problem and Solution

Imagine having the task of fetching the creation timestamp of a specific file through Paramiko’s SFTP module. To achieve this, we need to establish an SFTP connection to the server where the target file resides. Subsequently, we can access and showcase its creation timestamp accurately.

To tackle this challenge effectively, we will proceed with the following steps: 1. Connect to the remote server utilizing Paramiko. 2. Retrieve the attributes associated with the designated file. 3. Extract and present the creation timestamp of the file elegantly.

Code

import paramiko

# Establish SSH transport session with host
transport = paramiko.Transport(('hostname', 22))
transport.connect(username='username', password='password')

# Create SFTP client from transport session
sftp = paramiko.SFTPClient.from_transport(transport)

# Specify path of target file on remote server
filepath = '/path/to/file.txt'

# Get attributes of specified file and extract creation time
file_attributes = sftp.stat(filepath)
creation_time = file_attributes.st_ctime

print(f"Creation Time: {creation_time}")

# Close SFTP session and transport connection
sftp.close()
transport.close()

Explanation

The provided code snippet initiates an SSH transport session with a remote host using Paramiko, followed by creating an SFTP client from this established transport session. By specifying the filepath of our target file on the server, we can retrieve its attributes, specifically focusing on extracting its creation time for display purposes.

This solution leverages Paramiko’s Transport for connectivity establishment, SFTPClient for seamless interaction with files over SFTP, and accessing specific attributes like st_ctime to fetch a file’s creation time accurately.

    How do I install Paramiko in Python?
    • You can effortlessly install Paramiko via pip by executing pip install paramik.

    Can I securely connect to servers using Paramiko?

    • Absolutely! With Paramiko, you can securely establish connections to servers via SSH.

    What does st_ctime attribute represent in Python?

    • In Python, the st_ctime attribute signifies the inode change time in Unix systems; it denotes when metadata related to a particular inode was modified.

    Is it possible to transfer files over SFTP with Paramiko?

    • Certainly! Utilizing Paramiko allows you to securely transfer files over SSH File Transfer Protocol (SFTP).

    How can I handle authentication while connecting via Paramiko?

    • When establishing connections through methods like .connect(username=…, password=…), you can conveniently provide credentials such as username/password for authentication purposes.

    Can I automate tasks on remote servers with Python and Paramiko?

    • Undoubtedly! By leveraging methods offered by the Paramiko module, you can automate tasks effectively on remote servers in Python.

    Are there any alternative libraries for working with SSH/SFTP in Python?

    • While Paramiko stands out as an excellent choice for SSH/SFTP operations, other alternative libraries like PxSSH or Fabric also provide comparable functionalities.

    How do I handle exceptions and errors while working with SFTPinPython?

    • It is crucial to implement adequate error handling mechanisms while working on networking tasks in Python. Ensure inclusion of a finally block to properly close connections and clean up resources within your code.

    Conclusion

    In conclusion, you have acquired valuable insights into fetching a creation timestamp of a file using Paraki’s SFT module in Pyton. This knowledge equips you not only to handle such tasks proficiently but also serves as a foundation for tackling more intricate file manipulation activities on remote servers effectively.
