Sooner or later, we will need to edit files from the shell command line. In many Debian systems, the default text editor is vi. If you're not comfortable with it, you probably could use a friendlier alternative. In Ubuntu systems, the default text editor is nano. You might prefer it since it's easier to use. In case it's not available in your server, it can be installed with:

$ sudo apt-get install nano

In the following sections, we will assume nano as the preferred editor. If you prefer any other editor, feel free to adapt the commands accordingly.

The Samba service helps make Linux file-sharing services compatible with Microsoft Windows systems. We can install it on our Debian/Ubuntu server with this command:

$ sudo apt-get install samba samba-common-bin

The samba package installs the file-sharing services, and the samba-common-bin package is needed for the smbpasswd tool. By default, users allowed to access shared files need to be registered with it. We need to register our user, odoo for example, and set a password for its file share access:

$ sudo smbpasswd -a odoo

After this, we will be asked for a password to use to access the shared directory, and the odoo user will be able to access shared files for its home directory, although it will be read only. We want to have write access, so we need to edit the Samba configuration file to change it as follows:

$ sudo nano /etc/samba/smb.conf

In the configuration file, look for the [homes] section. Edit its configuration lines so that they match the settings as follows:

[homes] 
    comment = Home Directories 
    browseable = yes 
    read only = no 
    create mask = 0640 
    directory mask = 0750 

For the configuration changes to take effect, restart the service:

$ sudo /etc/init.d/smbd restart

To access the files from Windows, we can map a network drive for the path \\<my-server-name>\odoo using the specific username and password defined with smbpasswd. When trying to log in with the odoo user, you might encounter trouble with Windows adding the computer's domain to the username (for example, MYPC\odoo). To avoid this, use an empty domain by prepending a \ character to the login (for example, \odoo):

If we now open the mapped drive with Windows Explorer, we will be able to access and edit the contents of the odoo user's home directory:

Odoo includes a couple of tools that are very helpful for developers, and we will make use of them throughout the book. They are technical features and the developer mode. These are disabled by default, so this is a good moment to learn how to enable them.

The developer tools provide advanced server configuration and features. These include a debug menu in the top menu bar along with additional menu options in the Settings menu, in particular the Technical menu.

These tools come disabled by default, and to enable them, we need to log in as admin. In the top menu bar, select the Settings menu. At the bottom-right, below the Odoo version, you will find two options to enable the developer mode; any of them will enable the Debug and Technical menus. The second option, Activate the developer mode (with assets), also disables the minification of JavaScript and CSS used by the web client, making it easier to debug client-side behavior:

After that, the page is reloaded and you should see a bug icon in the top menu bar, just before the session user avatar and name providing the debug mode options. And in the Settings option in the top menu, we should see a new Technical menu section giving access to many Odoo instance internals:
