Description David Stockdale 2020-05-03 12:17:01 UTC
Description of problem:

The packaged version Bind is currently built with XML support, but not JSON, limiting the functionality of statistics channels. We use the JSON interface to pull statistics into our monitoring platform.

Rebuilding the SRPM with "BuildRequires: json-c-devel" added to the SPEC file enables the desired functionality.


Version-Release number of selected component (if applicable): 9.11.4-26.P2


How reproducible: Readily


Steps to Reproduce:
1. Toggle SELinux boolean to permit Bind to listen on HTTP port:

setsebool named_tcp_bind_http_port on

2. Add statistics-channels configuration to named.conf:

statistics-channels {
        inet 127.0.0.1 port 80 allow { 127.0.0.1; };
};

3. Start/Restart Bind

4. Check version details and try to access JSON interface

Requires just json dependency on build time. Added already to Fedora by commit [1], then enabled later.

Comment 4 Petr Menšík 2021-01-05 13:56:29 UTC
Closing as duplicate, even it was filled sooner. More recent bug has acks and reference to customer, giving it a higher priority.
