Why is a mount of a remote samba share read only?

Question

I have successfully mounted a samba share (from a Centos server) on my Raspberry Pi, but the share is read-only: sudo mount -t cifs //ip.address/sharename /mnt/test -o user=username,vers=1.0

I have also (with it unmounted) issued chmod 666 /mnt/test as I found reports that resolved the issue.

I can access the share read/write from Windows machines and linux machines. In fact, using the Raspberry Pi's File manager and putting smb://ip.adddress/sharename in the address bar, I can write to the folder without having it mounted.

I have tried shares on more than one machine and they all mount as read-only.

What have I missed in mounting the share that causes it to be read-only?

(most questions are about why a Raspberry Pi share is read-only. To be clear my issue is not with shares on the Raspberry Pi but accessing shares on other computers).

[Edit] This is the smb.conf on the server that I am trying to connect to:

[User]
        comment = User Files
        valid users = peter,powerpete,admin
        write list = peter,powerpete,admin
        path = /mnt/md0/shares/user/

Answer 1

maybe this will help you

cat /etc/samba/smbd.conf on my server:


[media]
path = /home/pi/shared/data/media
read only = no
public = yes
writable = yes
create mask = 0777
directory mask = 0777

then mounting script on my raspberry machine:

#!/bin/bash
sudo mount -t cifs -o uid=1000,gid=1000,user=pi,pass=`cat /home/pi/samba.cred` //server-IP-or-name/media /home/pi/shared/data/media

then the mounted share is fully read/write on raspberry on other machines - i.e. my Macbook - it works without even asking for user/password - just mount as Guest I have no Windows to check it
