sftpretty

A pretty quick and simple interface to paramiko SFTP. Provides multi-threaded routines with progress notifications for reliable, asynchronous transfers. This is a Python3 optimized fork of pysftp with additional features & improvements.

• Built-in retry decorator
• Hash function for integrity checking
• Improved local & remote directory mapping
• Improved logging mechanism
• More tests
• Multi-threaded directory transfers
• Progress notifications
• Support for ciphers, digests, disabled algorithms, kex & key type connection options
• Support for ED25519 & ECDSA keys
• Support for private key passwords
• Thread-safe connection manager

Example

from sftpretty import Connection


# Basic

with Connection('hostname', username='me', password='secret') as sftp:
    # Temporarily chdir to public/.
    with sftp.cd('public'):
        # Upload file to public/ on remote.
        sftp.put('/my/local/filename')
        # Download a remote file from public/.
        sftp.get('remote_file')


with Connection('hostname', private_key='~/.ssh/id_ed25519',
                            private_key_pass='secret') as sftp:
    # Upload local directory to remote_directory.
    sftp.put_d('/my/local', '/remote_directory')

    # Recursively download a remote_directory and save it to /tmp locally.
    sftp.get_r('remote_directory', '/tmp')


# Advanced

with Connection('hostname', username='me', password='secret') as sftp:
    # Upload local directory to remote_directory. On occurance of any
    # exception or child of, passed in the tuple, retry the operation.
    # Between each attempt increment a pause equal to backoff * delay.
    # Run a total of tries (six) times including the first attempt.
    sftp.put_d('/my/local', '/remote_directory',
               exceptions=(NoValidConnectionsError,
                           socket.timeout,
                           SSHException),
               tries=6, backoff=2, delay=1)


with Connection('hostname', private_key='~/.ssh/id_ed25519',
                            private_key_pass='secret') as sftp:
    # Recursively download a remote_directory and save it to /tmp locally.
    # Don't confirm files, useful in a scenario where the server removes
    # the remote file immediately after download. Preserve remote mtime on
    # local copy
    sftp.get_r('remote_directory', '/tmp', confirm=False,
               preserve_mtime=True)
