Hi there, I have a strange issue with DNSMasq: it looks like it saves dns cached query and keep them after a restart. Here is the problem: the host opaplnx13 didn't reverse lookup and I saw this in DNSMasq logs. I fixed the problem in "master DNS servers" and they actually reverse lookup opaplnx13 correctly but DNSMasq actually does not. It doesn't even after a restart.
10.145.3.71 and 10.145.3.72 are DNSMasq servers 10.145.1.121 is a master server [root@opaplnx23 etc]# nslookup > server 10.145.3.71 Default server: 10.145.3.71 Address: 10.145.3.71#53 > 10.145.3.41 Server: 10.145.3.71 Address: 10.145.3.71#53 ** server can't find 41.3.145.10.in-addr.arpa: NXDOMAIN > server 10.145.3.72 Default server: 10.145.3.72 Address: 10.145.3.72#53 > 10.145.3.41 Server: 10.145.3.72 Address: 10.145.3.72#53 ** server can't find 41.3.145.10.in-addr.arpa: NXDOMAIN > server 10.145.1.121 Default server: 10.145.1.121 Address: 10.145.1.121#53 > 10.145.3.41 Server: 10.145.1.121 Address: 10.145.1.121#53 41.3.145.10.in-addr.arpa name = opaplnx13.intra.azosp.vr.it. In DNSMasq log I can see: Aug 25 16:21:06 dnsmasq[6373]: query[PTR] 41.3.145.10.in-addr.arpa from 10.145.3.69 Aug 25 16:21:06 dnsmasq[6373]: config 10.145.3.41 is NXDOMAIN-IPv4 How is it possible? Is there a cache file somewhere? Many thanks Piero -- Stupid is as stupid does. Forrest Gump
