'Connect to Explicit FTPS (FTPES) with Python (error) [duplicate]
I'm uploading a file ftp and keep getting a "ssl.SSLEOFError: EOF occurred in violation of protocol (_ssl.c:2756)" error.
class MyFTP_TLS(ftplib.FTP_TLS):
"""Explicit FTPS, with shared TLS session"""
def ntransfercmd(self, cmd, rest=None):
conn, size = ftplib.FTP.ntransfercmd(self, cmd, rest)
if self._prot_p:
session = self.sock.session
if isinstance(self.sock, ssl.SSLSocket):
session = self.sock.session
conn = self.context.wrap_socket(conn,
server_hostname=self.host,
session=session) # this is the fix
return conn, size
tp = MyFTP_TLS()
ftp.ssl_version = ssl.PROTOCOL_TLSv1_2
ftp.connect(server, 21)
ftp.set_pasv(True)
ftp.auth()
ftp.prot_p()
ftp.login(user, passwd)
print("Success connection")
ftp.set_debuglevel(2)
ftp.encoding = "utf-8"
#ftp.getwelcome()
with open(dest_filename,"rb") as file:
try:
ftp.storbinary(f"STOR {dest_filename}", file)
except:
ftp.quit()
os.remove(dest_filename)
ftp.quit()
os.remove(dest_filename)
Why is this throwing an error? Ideas?
Solution 1:[1]
This is the code I ended up using. It extends the ftp python class. Basically, do a ftp = MyFTP_TLS() and then do all the calls you want, like ftp.login(user,passwd) etc like normal.
`class MyFTP_TLS(ftplib.FTP_TLS):
#Explicit FTPS, with shared TLS session
def ntransfercmd(self, cmd, rest=None):
conn, size = ftplib.FTP.ntransfercmd(self, cmd, rest)
if self._prot_p:
conn = self.context.wrap_socket(conn,
server_hostname=self.host,
session=self.sock.session) # reuses TLS session
conn.__class__ = ReusedSslSocket # we should not close reused ssl socket when file transfers finish
return conn, size`
