I tried to test it, steps as below:
(1) add a zone "x.test.com", and assign an A record into it:
ns.x.test.com. 60 IN A 192.168.1.246
(2) to reload bind every 1 second, using a shell script:
#!/bin/sh
while [ 1 ];do
/usr/local/bind/sbin/rndc reload
sleep 1
done
(3) to make DNS query to this named every 1/10 second, using a perl script:
use strict;
while(1) {
my @x = `dig ns.x.test.com \...@localhost +short`;
my $x = shift @x;
chomp $x;
print "wrong: $x\n" if ($x ne '192.168.1.246');
select(undef, undef, undef, 0.1);
}
(4) run both shell and perl scripts, and watch the results output of perl
script.
After tested for some time (ie, 10 minutes), I got nothing from perl script's
output.
So I assume that when named is reloading, it doesn't affect user's query.
Am I right? thanks for any helps.
