Hello!
I'm trying to execute the example code:

>>> from ftplibtls import FTP_TLS
>>> ftp = FTP_TLS('servername')  # default port 21
>>> ftp.login('username', 'password')
>>> ftp.prot_p()
>>> ftp.retrlines('LIST')

But I'm getting this error:

Traceback (most recent call last):
File "boot.py", line 71, in
File "modules/ftplib.py", line 510, in retrlines
File "modules/ftplibtls.py", line 110, in ntransfercmd

OSError: [Errno 12] ENOMEM
MicroPython v1.22.1 on 2024-01-05; Generic ESP32 module with ESP32

The connection is successful, I don't have problems with the other functions, only with dir(), in addition to this one.

Hi,

I've got the same problem as previous person... (#2)
I can't connect to any server, debugging gives the same answer. I've tried pinging the server from my ESP32 and it works fine.

Hello! I'm using the libraries inside the folder esp.
I want to download a file from a server with the following code:

fileToWrite = open("comoEstan.txt", "wb")
def handleDownload(block):
    fileToWrite.write(block)

result = ftp.retrbinary('RETR comoEstan.txt', handleDownload)
print('ftp download comoEstan.txt return code=', result)

But I'm getting the following error:

Traceback (most recent call last):
File "", line 53, in
File "ftplib.py", line 553, in retrbinary
File "ftplib.py", line 89, in getattr
AttributeError: 'SSLSocket' object has no attribute 'recv'

Hy!

I'll try to test " ftplib.py" in my Rasp Pico W using Thonny IDE.

When I run "ftp_example.py" as is, the follow error msn appears

Testing
Traceback (most recent call last):
  File "<stdin>", line 4, in <module>

Can I use it on ESP32 directly? I succesfully imported it on my board, but couldn't connect to FTP server.

Hi , I don't know if I am doing something wrong .
I have an esp-32 :
https://www.az-delivery.de/it/products/esp32-developmentboard
With micropython installed , and I am using Thonny .
I loaded on the esp32 , theftplib.pyfile .
And then in the boot.py file I added the line :

from ftplib import FTP

In main.py , after I connect to the wifi network , I try to access an ftp server local on the ip 192.168.1.1

the part of code dedicated to ftp in main.py is :

ftp= FTP('192.168.1.1',21,'user','password')
print('done')

When I try to run the code an error message comes up :

Could not connect to('192.168.1.1',21)
I confirm that the server is working ( i login in it with my computer) , and that the esp32 is able to ping the ip 192.168.1.1

EDIT:
Maybe i was wrong , i realized thay maybe i was using the wrong library , i have to use the library inside the esp folder right?

Hello
Here is my code :

import network
from ftplibtls import FTP_TLS

status_reseau = connect_wifi_local("NETWORK", "123456789")[1]

if status_reseau == 3:

    try:
        
        ftp_tls = FTP_TLS()
        print("1")
        ftp_tls.connect(adresse_serveur, port)
        print("2")
        ftp_tls.login(utilisateur_1, mot_de_passe_1)
        print("3")
        ftp_tls.prot_p()
        print("4")
        files = ftp_tls.nlst()
        print(files)
        
    except Exception as e:
        erreur = str(e)
        print("Erreur FTPS : " + str(e))

But I have the following error on the login line :

Erreur FTPS : extra keyword arguments given

Someone can help me?

Thx

Are you going to implement the FTPS or SFTP protocols?

I test the download and upload function, upload func works,but the download func have same problem, can not find the download file.

code:

result = ftp.retrbinary('RETR aaaaaa.dxf', progress)
print('ftp download aaaaaa.dxf return code=', result)

with open('README.pdf', 'rb') as fp:
    result = ftp.storbinary('STOR README.pdf', fp)
    print('ftp upload README.pdf return code=', result)`

serial print:

ftp download aaaaaa.dxf return code= 226 Transfer complete.
ftp upload README.pdf return code= 226 Transfer complete.

MicroPython v1.13 on 2020-09-02; ESP32 module with ESP32
Type "help()" for more information.

>>> import os
>>> os.listdir()
['README.pdf', 'esp', 'ftp.py', 'ftp_pycom.py', 'ftp_thread.py', 'ftpadvanced.py', 'ftplib.py', 'ftplibtls.py', 'main.py', 'uftpd.py']

where is the download file aaaaaa.dxf?

It seems that the parsing in test_ftplib_cmdline.py uses the same split character for password and port.
This causes specifying a user:pass to fail.

Suggest using another delimiter perhaps + between user and password

Thank you

When uploading a file larger than ~5kb, my ESP32 freezes. I tried collecting garbage to reduce memory usage, but this did not help. smaller files usually upload fine.

P.S.: If someone would sponsor me by sending me a Pico W board, I could "officially" support the Pico W port 😀

It would be slightly impractical for me to ship one to you from Canada, so what level of one-off sponsorship would you need to buy one from the BerryBase link you referenced?

Thanks for making this port of ftplib available. I am having issues importing it on esp8266 though.

If I import the esp8266 port compiled to mpy, I get the error:

>>> import ftplib

ValueError: incompatible .mpy file

If I import the esp8266 port as a py file, I get the error:

>>> import ftplib

MemoryError: memory allocation failed, allocating %u bytes 

Is there any simple fix you can think of?

I ran into 2 issues which i "fixed?" I'm new to Python so these fixes are not authoritative.
In ftplib in "def connect(self, addr):"
the code reads: self._sock.connect(_resolve_addr(addr))
but this gives an error deep in \micropython-1.19.1\py\obj.c "requested length 2 but object has length 1"
_resolve_addr(addr) returns an array with 1 element, but connect wants 2 - IP and port
the addr is already resolved.
I "fixed" by changing to: self._sock.connect(addr)

Then i encountered a python error in getmultiline at "line = line + (b'\n' + nextline)"
but line and nextline are both str, Python moans about concat a byte with a string
I "fixed" by: line = line + "\n" + nextline)

With those two changes i was able to log onto a server, list files, change dir, upload a file, quit, and close.

What is your opinion of my fixes?

thank for your project, I can download files , but I can not get file sizes, can your help me.

code:

from ftpadvanced import AdvancedFTP

ftp.login()
files = ftp.nlst()
print(files)
print('sizes=', ftp.size('aaaaaa.dxf'))#error

Hi there,

I'm getting the error mentioned in #2 and #4

This is my code:

from ftplib import FTP
ftp = FTP()
ftp.set_debuglevel(2)
ftp.connect('ftp1.at.proftpd.org')

I also added print('addrinfos: ', addrinfos) before line 227 in ftplib.py as suggested in #2 (comment)

This is what I'm getting:

addrinfos:  [(2, 1, 0, '', ('86.59.114.198', 21))]
requested length 2 but object has length 1

Traceback (most recent call last):
  File "<stdin>", line 44, in <module>

  File "ftplib.py", line 243, in _create_connection
Error: Could not connect to ('86.59.114.198', 21)

I was able to create a raw socket connection with this code #4 (comment), it works just fine

import usocket

IP_ADDRESS = 'ftp1.at.proftpd.org'

sock = usocket.socket()
sockaddr = usocket.getaddrinfo(IP_ADDRESS, 21)[0][-1]
sock.connect(sockaddr)

This is what I get with the code above (there's no error):

I got this error while trying to establish an ftp connection between esp32 and the server

When I run setup.py on a new pico 2 W it gives an "ImportError: no module names 'setuptools'". I get stuck here. I am unable to find setuptools for micropython. Any assistance is appreciated.
