| Re: [mosquitto-dev] Unable to start mosquitto - problem with password file |
Shan
Thanks for this.
What issues do these commands actually fix? (My /etc/mosquitto/passwd
file, as generated by mosquitto_password, currently has owner read
& write access.)
Unclear about the form of the chown command. What is the "1883"
value? My reading of the man page is that these values should
either be UID and GID values, or user names as aliases for these.
My /etc/mosquitto/passwd file is currently owned by root, which
seems right to me for a file that will be accessed by a process
executed by systemd. Or maybe I am misunderstanding?
Some problem with file access rights (as opposed to existence)
seems a good call. But I cannot see anywhere in the docs what
these need to be.
Best,
P.
Hi Peter,
yes the forwards compatibility from 2.0.18 is not very intuitive. I suggest trying to do:
```sudo chmod 0400 -R /etc/mosquitto/ && sudo chown 1883:1883 -R /etc/mosquitto/```
I faced the same issue when setting up my mosquitto container.
regards,
shan

Having successfully used mosquitto a few years ago, I am trying to
install it on a couple of new machines. I have downloaded the latest
version from the PPA. All works fine on install.
My problems come when I try to modify the default conf file. Mosquitto
fails to (re)start with an exit code of 13, which I have run down to the
mosquitto log file entries of:
mosquitto version 2.0.18 starting
Config loaded from /etc/mosquitto/mosquitto.conf.
Error: Unable to open pwfile "/etc/mosquitto/passwd".
Error opening password file "/etc/mosquitto/passwd".
I am generating the password file using the mosquitto_password utility,
which exits with a zero error code; in fact, I am using the example in
the docs. The password file looks sensible with the contents of:
username + ":" + a hashed password. I have even checked the file has
root R/W access.
Convinced I have not made a dumb mistake in mistyping the pathname - I
have cut-and-pasted the results of "ls /etc/mosquitto/passwd" directly
into the conf file. Also run it past colleagues who can't seen any typos.
The actual conf file I am using is:
persistence true
persistence_location /var/lib/mosquitto/
log_dest file /var/log/mosquitto/mosquitto.log
connection_messages true
allow_anonymous false
password_file /etc/mosquitto/passwd
listener 1883 localhost
Using Mosquitto 2.0.18 on Linux Mint v21.2
Any ideas? This all worked beautifully for me a few years ago... 🙁
