I'm trying to make a server for all the sensors on my boat.
To do this I installed armbian on a solar powered bananapi m2 zero. And installed mosquito with the following commands:
wget (I'm not allowed to use links because I'm a new user) link to mosquito-repo. Gpg. Key
sudo apt-key add mosquitto-repo.gpg.key
cd /etc/apt/sources.list.d/
sudo wget (I'm not allowed to use links because I'm a new user), repo.mosquitto.org/debian/mosquitto-bookworm.list
apt-get update
sudo apt install mosquitto mosquitto-clients
It gave a warning about apt.key being depreciated but installed ok.
Once this was done, I tested it and it worked.
then I tried to secure my mosquitto broker following information on a digitalOcean site (Suggested by google)
I executed the following commands:
sudo mosquitto_passwd -c /etc/mosquitto/passwd bert
And made a default.conf file with:
sudo nano /etc/mosquitto/conf.d/default.conf
containing the following:
allow_anonymous false
password_file /etc/mosquitto/passwd
With a trailing newline, (which I think is a enter after the last command?)
Following this, I attempted to restart the broker using:
sudo systemctl restart mosquitto
Witch didn't work and gave the following error:
Job for mosquitto.service failed because the control process exited with error code.
See "systemctl status mosquitto.service" and "journalctl -xeu mosquitto.service" for details.
I tried "systemctl status mosquitto.service":

I feel like it's something simple, but I'm not sure what it is.
Can somebody please help me so I can move on to enable SSL encryption, install nodejs and node-red and start playing around with the sensors I have.
Help would be greatly appreciated

Small update
I found out how to find the owner of a process in Linux, which was 'mosquitto' and changed the ownership of the password file to that.
Restarted mosquito and all went well.
'Systemctl status mosquito. Service' said that all was running nicely, and 'journalist -Xe mosquito. Service' that it loaded '/etc./mosquito/conf.d/default. conf' as far as I can see without problems.
So I started testing it with:
mosquitto_pub -h localhost -t "test" -m "hello world"
And it gave no errors, which I found strange because I thought that the line
in default.conf would disable all non-authenticated connections.
then i tested it with
mosquitto_sub -h localhost -t test -u "bert" -P "password"
(where password is substituted with the real password) and it worked also
so I'm a step further than I was, but I'm still not there, I want mosquitto to refuse connections without user and password.
If someone can lend me a hand in getting this done, I would appreciate it
