I had a samba shared drive that use to work fine for my ubuntu workstation but wasn't available on Windows computers. The setup allowed for anonymous users to access it and this is not permitted on Windows (unless some settings are changed) To enable access to Windows running computers, I created users and passwords for all who wanted to connect to it.
Now, Windows users can read and write on it but I can't write on my ubuntu station. I also have problems mounting it at startup, the fstab file is no longer working.
The drive fs is NTFS and I think this is the main culprit. I tried to chmod and chown the folder but nothing changed: all files and folder are 755.
But I must admit that I am very confused as to what is really happening here.
My fstab file is copied here:
//192.168.1.2/ext4tb /mnt/ext4tb cifs ,credentials=/home/frepie/.smbcredentials,iocharset=utf8,vers=3.0,file_mode=0777,dir_mode=0777 0 0
Seems problem in samba configuration. Try to create share like this:
