Hello, I'm running Confluent com a cluster and it seems that dnsmasq does not work as expected: [root@mmgt01 etc]# !nslookup nslookup cn003 Server: 127.0.0.1 Address: 127.0.0.1#53 Name: cn003.cluster.domain.com Address: 172.28.0.3 ** server can't find cn003.cluster.domain.com: REFUSED Any ideia why it get's refused but resolves? This issue many times slows down name resolution. Here's /var/log/messages: Oct 22 00:29:02 mmgt01 dnsmasq[400928]: reading /etc/resolv.conf Oct 22 00:29:02 mmgt01 dnsmasq[400928]: ignoring nameserver 172.28.253.1 - local interface Oct 22 00:29:02 mmgt01 dnsmasq[400928]: read /etc/hosts - 181 addresses Oct 22 00:32:14 mmgt01 dnsmasq[400928]: reading /etc/resolv.conf Oct 22 00:32:14 mmgt01 dnsmasq[400928]: ignoring nameserver 172.28.253.1 - local interface Oct 22 00:32:15 mmgt01 dnsmasq[400928]: reading /etc/resolv.conf Oct 22 00:32:15 mmgt01 dnsmasq[400928]: ignoring nameserver 172.28.253.1 - local interface Oct 22 00:32:53 mmgt01 dnsmasq[400928]: reading /etc/resolv.conf Oct 22 00:32:53 mmgt01 dnsmasq[400928]: ignoring nameserver 172.28.253.1 - local interface Oct 22 00:32:53 mmgt01 dnsmasq[400928]: reading /etc/resolv.conf Oct 22 00:32:53 mmgt01 dnsmasq[400928]: ignoring nameserver 172.28.253.1 - local interface Oct 22 00:34:32 mmgt01 dnsmasq[400928]: reading /etc/resolv.conf Oct 22 00:34:32 mmgt01 dnsmasq[400928]: ignoring nameserver 127.0.0.1 - local interface Oct 22 00:34:32 mmgt01 dnsmasq[400928]: reading /etc/resolv.conf Oct 22 00:34:32 mmgt01 dnsmasq[400928]: ignoring nameserver 127.0.0.1 - local interface Oct 22 00:34:38 mmgt01 dnsmasq[400928]: exiting on receipt of SIGTERM Oct 22 00:34:38 mmgt01 systemd[1]: dnsmasq.service: Succeeded.
