scp module for paramiko

Pure python scp module

The scp.py module uses a paramiko transport to send and recieve files via the scp1 protocol. This is the protocol as referenced from the openssh scp program, and has only been tested with this implementation.

Example

from paramiko import SSHClient
from scp import SCPClient

ssh = SSHClient()
ssh.load_system_host_keys()
ssh.connect('example.com')

# SCPCLient takes a paramiko transport as its only argument
scp = SCPClient(ssh.get_transport())

scp.put('test.txt', 'test2.txt')
scp.get('test2.txt')

scp.close()

$ md5sum test.txt test2.txt
fc264c65fb17b7db5237cf7ce1780769 test.txt
fc264c65fb17b7db5237cf7ce1780769 test2.txt

Using 'with' keyword

from paramiko import SSHClient
from scp import SCPClient

ssh = SSHClient()
ssh.load_system_host_keys()
ssh.connect('example.com')

with SCPClient(ssh.get_transport()) as scp:
    scp.put('test.txt', 'test2.txt')
    scp.get('test2.txt')

$ md5sum test.txt test2.txt
fc264c65fb17b7db5237cf7ce1780769 test.txt
fc264c65fb17b7db5237cf7ce1780769 test2.txt

Uploading file-like objects

The putfo method can be used to upload file-like objects:

import io
from paramiko import SSHClient
from scp import SCPClient

ssh = SSHClient()
ssh.load_system_host_keys()
ssh.connect('example.com')

# SCPCLient takes a paramiko transport as its only argument
scp = SCPClient(ssh.get_transport())

# generate in-memory file-like object
fl = io.BytesIO()
fl.write(b'test')
fl.seek(0)
# upload it directly from memory
scp.putfo(fl, '/tmp/test.txt')
# close connection
scp.close()
# close file handler
fl.close()
