DNSSEC doesn't work

My DNS servers aren't generating keys. I noticed in the source code of ISPConfig (bind_plugin.inc.php) the following:

Code:

        if (file_get_contents('/proc/sys/kernel/random/entropy_avail') < 400) {
            $app->log('DNSSEC ERROR: We are low on entropy. Not generating new Keys for '.$domain.'. Please consider installing package haveged.', LOGLEVEL_WARN);
            echo "DNSSEC ERROR: We are low on entropy. Not generating new Keys for $domain. Please consider installing package haveged.\n";
            return false;
        }

Checking the contents of the file "/proc/sys/kernel/random/entropy_avail", the value is 134. I have no idea what this is. Can I just change the value of the file and done? any suggestion?

 

I've followed these steps:

I suggest to include the following commands:

Code:

systemctl start haveged
systemctl enable haveged

Thank you!

 

If a server has a mirror server, is DNSSEC turned off?

 

Hi,
I want to implement DNSSEC.
I am currently using ISPConfig 3.1 mirror setup.
Kindly let me know does this version(3.1) is having DNSSEC support for mirror setup.
Kindly note we are the service provider.We are having our own DNS.So it is compulsory for us to implement DNSSEC.
