Hello i know this problem has been asked a lot here and there, i tried multiples solution without any success :'c so i’m heading here praying for help :pray:

to explain my projet, i’m currently making a end year projet for my IT school, and i must provide an cloud for tiny companies .

with my lack of fund and support (just an ESXi and some competences in windows server) i decided to run nextcloud with a windows file server, like that you can access your file (on the windows file server) with vpn + UNC connection in windows file explorer, but you can also use an https connection to nextcloud to manage your file,
nextcloud is just connected with SMB/CIFS connection on the windows file server.

so here’s the problem, i can’t upload a file on those SMB shared folder, i can on the local disk of nextcloud, but not on the share of the file server.

so it’s maybe a right permissions problem ? Between the nextcloud server and the windows fileserver ?

but i shearched everywhere i could, without any success .

thanks for your response and help.

Bye !

Hi, this looks like Files on SMB-share corrupted while up- and downloading · Issue #26457 · nextcloud/server · GitHub to mee…

Hello ! Thanks for your response.

I don’t think so, i don’t have any corrupted file problem, i can still navigate in my share even create folder and text file inside those share, but i still can’t upload anything :confused:

Any other suggestions ?

No, unfortunately :confused:

Ok thank you ^^

Anyone else ?

Hey man, hope your are doing well…

Can you please attach your smb.conf here?

Please hide any fragile information.

#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which 
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
#  - When such options are commented with ";", the proposed setting
#    differs from the default Samba behaviour
#  - When commented with "#", the proposed setting is the default
#    behaviour of Samba but the option is considered important
#    enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic 
# errors. 

#======================= Global Settings =======================

[global]

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will part of
   workgroup = WORKGROUP

# server string is the equivalent of the NT Description field
   server string = %h server (Samba, Ubuntu)

#### Networking ####

# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
;   interfaces = 127.0.0.0/8 eth0

# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself.  However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
;   bind interfaces only = yes



#### Debugging/Accounting ####

# This tells Samba to use a separate log file for each machine
# that connects
   log file = /var/log/samba/log.%m

# Cap the size of the individual log files (in KiB).
   max log size = 1000

# We want Samba to only log to /var/log/samba/log.{smbd,nmbd}.
# Append syslog@1 if you want important messages to be sent to syslog too.
   logging = file

# Do something sensible when Samba crashes: mail the admin a backtrace
   panic action = /usr/share/samba/panic-action %d


####### Authentication #######

# Server role. Defines in which mode Samba will operate. Possible
# values are "standalone server", "member server", "classic primary
# domain controller", "classic backup domain controller", "active
# directory domain controller". 
#
# Most people will want "standalone server" or "member server".
# Running as "active directory domain controller" will require first
# running "samba-tool domain provision" to wipe databases and create a
# new domain.
   server role = standalone server

   obey pam restrictions = yes

# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.
   unix password sync = yes

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<kahan@informatik.tu-muenchen.de> for
# sending the correct chat script for the passwd program in Debian Sarge).
   passwd program = /usr/bin/passwd %u

Okay, thank you.

But where’s your shares?

You should have at least one to share with your nextcloud’s server.

Add the following lines at the end of that file:

[MyShare]
path = /path/to/your/shared/folder
browsable = yes
writable = yes
guest ok = yes
read only = no
sync always = yes

This is an example to test only, if it works we can configure a proper share.

PS.: Make sure you have php-smbclient and smbclient installed in your nextcloud server.

I suppoe @Chankopek is using a Windows server or comparable as SMB-server…

10

I was supposing that too, but if he is using the MSSMB how he had the smb.conf file?

11

Well the shares (the host of the shares is a windows server indeed) have been added with the “external storage” app in the GUI of nextcloud

I don’t remember configuring this smb.conf file,

Smbclient is installed, and the php-smbclient i never found the package with apt install, i must check (i’m not at home for the next couples hours) don’t remember if i did found another way to install php-smbclient or not.

12

Well, so where did you pick the smb.conf file from? :laughing:

Okay man, make sure you have the php-smbclient installed, otherwise it will not connect.

In my case, this was the packages that I had to install to work with:

php-smbclient.x86_64 php74-php-smbclient.x86_64 libsmbclient.x86_64 php-icewind-smb.noarch

13

From etc/samba ? ^^ guess it come from smbclient package not the php-smbclient one

Thanks for the packages names, gonna try to install ASAP :wink:

14

Well, that’s strange.

Are you sure you did not install all the samba package?

The smbclient does not have the /etc/samba dir as a dependency.

But this should not cause any other erros, when you can, try installing those packages mentioned above and tell me if it works.

Good luck mate, all the best!

Regards.
