I use ubuntu in graphic mode but I am willing to move to text mode and let the PC serve media files.
I have a mount set i9nmy fstab file, so in text mode ubuntu will mount it, the question is…
I use to share a folder from the file manager, right click, and share
I though this would write the changes to /etc/samba/smb.conf but it does not, so I think that in text mode the share will not exist, how do I have to do to have the share enabled both, in text and graphic mode?
Like most files in /etc the Samba configuration is not writeable for a normal user. Unless something changed since I last used mainline Ubuntu, sharing a folder from the file manager does the equivalent of a net usershare add ... command. The configuration(s) for user shares are not stored in /usr/local/samba/lib/usershares/ as the manual page for ‘net’ states but in /var/lib/samba/usershares/. You can check whether the shares you create are usershares and are accessible by running net usershare list.
Not quite sure what you mean by ‘text mode’ ; do you mean running the system without a GUI (like a server …) or do you mean in a terminal ?
Anyway, I believe it should work in both.
