I'm thinking loudly if a tool to test the network configuration exists, I mean that experimented system administrator won't need it, but I see here people who are not really at ease when you speak to open a terminal, and after that they don't know what you need to write in it
In a lot of router we have a network diagnostic tool, why not here.
My concern is that it cannot be an additional module, because when you need it, you cannot install an optional module if you face some misconfigured network settings. Therefore the module should be installed with the base.
I could see a tab panels module where each additional module could put there a test of the services they brings, but at least I would see
of course we will have the choice to change the host as wanted.
@dev_team what do you think ?
