Hello everyone!
In the past I've been working with odoo and I got some problems so I asked for help from somebody who is officialy from odoo. My odoo knowledge now is much bigger than when I started.
When this guy was helping me, I've seen that he was using Ubuntu and he was having an localhost with my Odoo on it. My odoo is actually on premise so he was not working on live server, he was working on his localhost. His localhost was looking something like 0.0.0.0:8069, something like that.
Please, teach me how to do that because I want to make some changes and I don't want to broke my live environment.
