Hi

 

I have configured this share:

 

 

When I try to access it from a Kubuntu VM running on Unraid I can only read. As soon as I try to create/move/delete folders/files Dolphin complains with "Access denied". I get the same result using smbclient.

I also get the same result when changing the share to secure and then connect with the same username that has read/write rights and Dolphin also never asks for credentials.

 

However as soon as I mount the share within the VM with

mount -t cifs -o credentials=/home/tom/credentials/samba.txt,uid=tom,gid=tom,_netdev //tower.home/downloads /home/tom/downloads/

I have full access.

 

What am I doing wrong?

I don't want to mount all my shares across all the different VMs.

What is going on here? If I check with Dolphin I see this:

 

How is this possible if the share is set to public?

SMB perms are one thing, but then the smb user also needs to have write perms to the actual folder/files at the filesystem level. Usually those need to be owned by a user in the "users" group and have group write permissions.

All the files and folders on Unraid have these permissions. My understanding is that this should work.

However, after running this:

 

Permissions look like this now:

 

Dolphin is reporting this:

 

So it's working now.

 

I just don't understand why. The only difference is the execute flag and still the read/write behavior has changed. Can someone please explain?

Directory permissions in Linux are often misunderstood as most the time folks are usually more concerned about file permissions.  Try reading this and see if that helps:

One of the things which I tend to dislike about many of the file managers is that they tend to ignore the 'group'.  Unraid, in any type of a secured environment, tends to  use the 'group' and its permissions to access things. 

 

I do use File Managers (mostly, the built-in  Dynamix one) for file Unraid management but I use the standard Linux/Unix ls command for diagnosing  problems using these switches:

ls -al {/path-from-root-to-resource}

 

This will show everything you need to know...

@Frank1940 Thank you very much. I'm still a Linux Noob (started ~4 weeks ago) so I still stumble quite often and have to read up a lot of stuff. Sometimes I can't find the obvious answer and then people like you providing help in forums save my day ❤️

Click on SHARES

Then look under User Shares for the share in which you wan to change the permissions on. Next click on the icon to the left of the share name. These steps are basically indicated on this screenshot:
