Hi all,
I'm fairly new to perl and cgi scripts, I can find most of it on the web, but I've been unable to solve this riddle. Is it possible to query the unbound statistics from a cgi script? I can't seem to figure out how to do this without cron-ing a bash script and reading its output, I want them on-demand when a page is requested.
I think it's a permission issue, as far as I've been able to assess the webpages run under 'nobody' and unbound-control needs elevated rights to execute a peek at the statistics. I'm using the following command to do so: "unbound-control stats_noreset". That way I can query all the DNS info I want (for reporting purposes), because I don't think unbound was compiled with dnstap enabled. At least I haven't found anything to back that up, that would eliminate the need for peeking at stats, because an up-to-date database can be built (async). I will further investigate dnstap in a later stage.
Can someone point me in the right direction for peeking unbound statistics from perl/cgi scripts? I've tried sudo-ing (I'd rather not, for security reasons), separate bash scripts and qx/backticks, they all seem to fail with exit code 256 which seems to be a permission problem. Running anything from an SSH session obviously succeeds, because then I have all the rights I need.
Thanks in advance.
Cheers,
Rachid
