Chilkat2-Python

Disconnect from an SFTP Server

Demonstrates the Chilkat SFtp.Disconnect method, which closes the current SSH/SFTP connection. It takes no arguments. All remote file and directory handles from the session become invalid and must not be reused.

Background: Disconnecting releases the SSH transport and every SFTP handle opened on it. The object itself stays reusable, but a later session must repeat the full setup — Connect, authenticate, then InitializeSftp — because the SFTP subsystem does not survive a disconnect.
