Simple example

Server side

from sftp import sFTP 
ip = '127.0.0.1'
port = 8080 
file = r'C:\Users\Mohamed\Desktop\Phi\phi.py'
ftp = sFTP(ip, port)
resp = ftp.send(file)
if resp == 0:
    print('File sent')
else:
    print('Failed to send file')

Client side

from sftp import sFTP 
ftp = sFTP('127.0.0.1', 8080)
resp = ftp.recv()
if resp == 0:
    print('File received')
else:
    print('Failed to receive file')

Timeout

by default max time is set to 10 seconds, after 10 seconds without a connection the server closes.

Server side

from sftp import sFTP 
ip = '127.0.0.1'
port = 8080 
file = r'C:\Users\Mohamed\Desktop\Phi\phi.py'
ftp = sFTP(ip, port, max_time=15)
resp = ftp.send(file)
if resp == 0:
    print('File sent')
else:
    print('Failed to send file')

Client side

from sftp import sFTP 
ftp = sFTP('127.0.0.1', 8080)
resp = ftp.recv()
if resp == 0:
    print('File received')
else:
    print('Failed to receive file')

Verbose

verbose option is used for displaying messages, by default is set to False.

Server side

from sftp import sFTP 
ip = '127.0.0.1'
port = 8080 
file = r'C:\Users\Mohamed\Desktop\Phi\phi.py'
ftp = sFTP(ip, port, verbose=True)
resp = ftp.send(file)
if resp == 0:
    print('File sent')
else:
    print('Failed to send file')

Client side

from sftp import sFTP 
ftp = sFTP('127.0.0.1', 8080, verbose=True)
resp = ftp.recv()
if resp == 0:
    print('File received')
else:
    print('Failed to receive file')

Warning: Just like SSL/TLS, this FTP server is also not safe against MITM attacks
