[stork-users] Stork agent cannot connect through rndc

[Mik J]

Hello Slawek,

I did
# named-checkconf
open: /etc/named.conf: file not found

So I made a symbolic link
# ln -s /var/named/etc/named.conf /etc/named.conf
And ran again the command
# named-checkconf

However no improvement.

Which option is used along with named-checkconf because when I run it I don't see anything, it's silent.


At the moment I launch the stork agent as root so there shouldn't be file permission problems.

# ls -l /etc/rndc.key
-rw-r--r--  1 root  _bind  100 May 11 00:29 /etc/rndc.key
The permissions are not so good but I'll change them

I don't have any file specified in my named.conf except:
- Log files: for example
channel queries_errors_file {
        file "/var/log/query-errors.log" versions 3 size 5m;

- or zone files
zone "127.in-addr.arpa" {
    type master;
    file "/master/reverse/loopback";
    allow-transfer { localhost; };
};

I'm not sure my configuration is involved in this issue, maybe that's because I'm using Openbsd 7.5 and it has something specific.

Regards

Hello Mik!

Please check if your Stork agent user has rights to read the 
"named.conf" and "rndc.key" files and any other files referenced in 
"named.conf".

Stork uses "named-checkconf" to read the BIND 9 configuration and 
extracts the RNDC address and port from it.

I'm waiting for your feedback.
