I am new to Linux and tried to make a Samba share, to access files on an external hard drive (ext4), mounted on my Linux system, from a mac and a PC. I followed the steps on Ubuntu's website, and I can navigate in the share, but only in read-only. I would like all my shares to work with read-write permissions to the designated users.

Here is my smb.conf file:

#
# 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.

I upgraded from 11.3 to 12.0-U1 last weekend and mostly it was fine, except that now my SMB share is Read Only. I was before using root to access my server, which I realize has been disabled for security reasons, so I made a new user, new SMB share, and I've checked every single permission box I can see and I only have read access to the pool.

I do have write access to the new user's Home Directory, but that's kind of useless, all the media is in the rest of the pool.

For the SMB share I have it set to root of the pool as the path, and using Default share parameters. For it's Share ACL, I've given it SID S-1-1-0, Permission is FULL, Type=ALLOWED, Domain is blank, and Name=Everyone.

I'm at a bit of a loss how to get my new user to access the rest of my pool.

Simple Problem:

After updating to ios 18 i my smb nas is read only via Files App. Other tools can access my nas and write data.

So i waited for 18.2. Nothing fixed!

Anybody any Information about that? I will ask apple, but mostly they do not care.

I have a Raspberry Pi that is acting as a file server in my home and it has Samba installed.

Currently, Samba controls access to different hard drives/directories storing various media/data.

The pi account is the owner and is able to do anything with these folders when logged in. I am the only one with access to the pi account/password.

So far everything is working great.

However, I want to give other members of my family the ability to read anything in these folders, but not write. Also I do not wish to share the Pi login/password. For these reasons, I cannot simply give them the Pi login/password for them to access the Samba shares.

What I would like to do is the either have another account where they can login to use the Samba shares with read-only permissions, or better yet, access Samba without needing to log in at all (but with only read-only permissions). At the same time, I wish to allow Pi to continue to do anything including write to these folders, so I cannot simply change the directory permissions to disable write for instance. In other words, I want Pi to be able to write/delete/modify, everyone else just read.

I have a few questions:

1. Is it possible to access a Samba share without logging in to Linux? Right now, when I use \\raspberrypi\share_name to access a share from Windows, I am asked to log in first before being granted access. I believe that at this point I am actually logging in to Linux ,not Samba (correct me if I am wrong since both Linux and Samba have a Pi account with the same password, so I am not totally sure on this).

2. If I enable guest access to the Samba share, will other users still have to login to Linux to get access to the share? In other words, is Linux login required even if guest access is allowed in Samba?

3. A different question: does Linux, in particular Raspbian Linux, allow guest logins? This may not be entirely relevant to the Samba sharing question, but I am just simply curious as to whether guest access is permitted on Raspbian through the standard login (not Samba).

4. Either way, is there a way to allow my family members on the local network to simply map to the Samba shares without logging in, but only have read-only access? How can this be done?

5. And if not, as a second choice I can create an account for the family members which would be either an actual guest account (if Raspbian allows this) or a normal user account with the same intent as a guest account (everyone will just use it to login to access Samba shares). But if so, how would I allow them read-only access to the shares?

Thanks!

I can't get my smb share to not be read-only, I just installed it on a raspberry pi and I've been messing with /etc/samba/smb.conf for a few hours and I get the sense this is supposed to be really easy. My share is:

[share]

Browseable = yes
Writeable = yes
only guest = no
create mask = 0700
directory mask = 0700
;Public = yes
;Guest ok = yes
force user = pi

I just don't see why it's read-only on every device I've connected to it on

I can't write to my NAS from my iPhone using the same credentials that I use successfully for my Mac, Windows, and Linux. It is displayed as read-only

I have a client environment where their "server" is running MacOS 12.3.1 and is sharing out folders using SMB with permissions -

User - read/write
Staff (group) - read/write
Everyone - read/write

When a Mac client connects to smb:/IPADDRESS/Share it mounts as expected. They can modify their own files and create new folders and files. However when a different user or Mac client connects they show permissions -

User - read only
Everyone - read only

So the Everyone permission doesn't appear to be working. The catch here is this ONLY affects the Mac clients. Windows clients connecting to the same server and shares have the permissions -

User - read/write
Everyone - read/write

I've searched for this issue and found many SMB issues with MacOS 12 but nothing about this exact situation. They are all about settings SMB permissions or revoking them. I tried revoking permissions and setting up from scratch, same issue. Tried revoking permissions, creating NEW user on client so it forces login, same issue. I'm stumped.

I've followed Apple KB to enable SMB2/3, same issues.

It gets more odd, when you are on the Mac client and create a new file/folder and check the permissions on the server, it should be read/write for everything BUT, it's not!

User - read/write
Staff (group) - read only
Everyone - read only

This leads me to wonder if the issue is with the Mac clients and not the server but I don't know what logs to gather to confirm this since it is working on Windows clients. Any suggestions?

EDIT: Solved. cleared Samba cache and configs worked.

I've been running a share on a raspberry pi for a while, and moving it to a more modern machine with Mint 22.

I started by creating users and groups.

Any idea why I can't write?

I've just spun up a new proxmox box. It's a single node so I haven't gotten into any zfs stuff.

One of the things I need it to do is share three WD usb hdd to my windows network as read only devices. Seems simple, right? Just spin up a container that has samba and away you go. But the devil's in the details and there are so many options.

My first though is to make a VM with a light weight Linux distro so I can use hardware passthrough. But is that the best approach? I know I could do this on the host, but I'd prefer to avoid that just to keep configurations tidy.

So, VM or LXC? Simple hand config of samba or install something larger like turnkey fileserver or truenas? I don't need any of the extra features nor external access so these seem like overkill.

What's the conventional wisdom here? I'm sure I'm over thinking this.

Hi everyone, For the past 3 days I've been trying to setup a samba folder on a NAS server I've built that is running Ubuntu 24.04(LTS). Following different guides I'm never able to get the folder working but having a different problem each time. Would someone be able to coach me step by step? Any advice on common mistakes is also welcome.

Im trying to create a read only samba share for my transmission Download server .

$ ls -lah
total 20K
drwxrwxrwx  1 root  root                  24 Dec  2 13:47 .
drwxr-xr-x 15 root  root                4.0K Dec 28 05:28 ..
drwxrwx---  1 rocky debian-transmission   36 Dec  9 15:15 Transmission

This is my configuration for smb.conf . The transmission directory is inside the Share directory.

[PiraSee]
    comment = Share       
    path = /media/Share 
    read only = yes
    browsable = yes
    create mask = 0666
    force create mode = 0666
    directory mask = 0777
    force directory mode = 0777

I suspect that the issue is with the transmission directory, since It's 'owned' by the transmission daemon. How do I make it so that other users can read the contents?

EDIT: I'm able to CD into the directory just fine when SSHing in, but I cant access it over Samba.
