Python SMB Connection

@DavinE this should be ok if you know the ip but not the smb name
print(smb_name)

This is: ELEKTROTECHNIK
i think that's correct!

smb_files = my_smb.getRemoteDir('', '*')
print(smb_files)

Here i get None

I you used my last post, that would say the ip is not correct.
The first my_smb is used to get the smb_name from the ip and the second uses the smb_name.

I print the smb_name, do you see it?

cvp

Now, this should work if you know the ip

from SMB_client import SMB_client

ip = 'xxx.xxx.xxx.xxx'
user = 'xxxxxx'
pwd = 'xxxxx'
my_smb = SMB_client()
smb_name = my_smb.getBIOSName(ip)
print('smb_name=',smb_name)
my_smb = SMB_client(username=user,password=pwd, smb_name=smb_name, print_errors=False)
my_smb.connect()
smb_files = my_smb.getRemoteDir('', '*')
for smb_file in smb_files:
	smb_filename = smb_file.filename
	print(smb_file.filename)

smb_files = my_smb.getRemoteDir('', '*')
for smb_file in smb_files:
	smb_filename = smb_file.filename
	print(smb_file.filename)

so i tried it with my Raspberry Pi2....
here is my output:

pi@RaspberryPi2:~/TEST/smb $ python smb_de.py 
('smb_name=', 'ELEKTROTECHNIK')
.
..
Drive

on my iPad pro 12.9" i get only:

smb_name=, ELEKTROTECHNIK

with the same user and pwd....
this is a iPad problem or ?

print('smb_name=',smb_name)

These lines do not use user nor pwd, it is only to get the smb_name that you need to use in tHe second. Note that if you know this smb_name, the ip is not necessary

my_smb = SMB_client(username=user,password=pwd, smb_name=smb_name, print_errors=False)
my_smb.connect()
smb_files = my_smb.getRemoteDir('', '*')
for smb_file in smb_files:
	smb_filename = smb_file.filename
	print(smb_file.filename)

pi@RaspberryPi2:~/TEST/smb $ python smb_de.py

This line is printed by the smb client, and it is not the same on iPad, it does not print anything, it is normal.

But is the connection ok?

DavinE

@cvp ,

this is my test code for my connection:

import smb, socket
from smb.SMBConnection import SMBConnection
from nmb.NetBIOS import NetBIOS

netbios = NetBIOS()

user = 'xxx'
pwd = 'xxx'

share_name          = "ELEKTROTECHNIK"
user_name           = user
password            = pwd
server_IP           = "xxx.xxx.178.251"
local_machine_name  = socket.gethostname()
server_machine_name = netbios.queryIPForName(server_IP)

print(server_machine_name[0])

# create and establish connection
conn = SMBConnection(user_name, password, local_machine_name, server_machine_name[0], domain="WORKGROUP", use_ntlm_v2=True)
# 139
# 445
print(conn.connect(server_IP, 139))

on my iPad i get here False

on my Raspi2 i get True.....

or need i to "translate" my Pwd on my iPad in Base64 ?

No.

Did you retry with the other port? 445

DavinE

@cvp
yes, its the same False

cvp

@DavinE you cold also remove ,use_ntlm_v2 = True) in the source code of SmB_client.py

Just to check

DavinE

@cvp
Its the same...

DavinE

@cvp

Do you know what protocol Pythonista use ?
SMB1; SMB2; SMB3 ?

cvp

@DavinE no idea.
Your code works on my NAS

DavinE

@cvp
Which on do you have ? WD or ?

and do you mean on your iPad ?

cvp

@DavinE my NAS is a WD
I work on an iPad. WitH your code.
It also works with a flash drive connected in usb slot of my router, drive that I always reach in smb.

cvp

Obviously, the smb module in Pythonista is old and is not identical as on your Radpberry.

When i use my Raspi with the data i get this:

it looks so but it sucks.... :(

cvp

@DavinE smb is not a standard module of Pythonista, in site-packages, thus you could try to install there the same as on your Raspberry.

DavinE

@cvp
smb is in the module of pysmb or ?
on my iPad an my Pi the version is the same.... 1.2.6
and i installed both with pip install pysmb
