Comments
jow-: Please provide your /etc/config/dhcp |
russell: Here you go:
config dnsmasq
option filterwin2k '0'
option rebind_localhost '1'
option local '/lan/'
option nonegcache '0'
option authoritative '1'
option readethers '1'
option leasefile '/tmp/dhcp.leases'
option resolvfile '/tmp/resolv.conf.auto'
option localservice '1'
option domainneeded '0'
option boguspriv '0'
option localise_queries '0'
option domain 'foo'
option expandhosts '0'
option nohosts '0'
option rebind_protection '0'
list notinterface 'pppoe-wan'
list server '/foo/111.222.33.44'
list server '/11.10.in-addr.arpa/111.222.33.44'
... plus a bunch of host and a few boot and mac sections, that don't look relevant. |
dedeckeh: Do you still observe the dnsmasq spam log with latest trunk ? |
Adminiuga: I can see the same messages from DNSmasq in the snapshot from 12/21/17 Only in my case the WAN interface was disabled deliberately, as I'm using it as an AP only.
DHCP -- pretty much default configuration. not using as a DHCP/DNS
DNSMasq query log |
Adminiuga: I can reproduce it with the snapshot from 12/21/17 |
rdslw: This still persists, even on 18.06.2 @hans, can you change status, as reporter provided all info. If you need anything more, let me know |
russell:
Supply the following if possible:

In my case, I have an upstream service provisioned with pppoe. Occasionally, the pppoe session dies as the ISP does some kind of unannounced maintenance. Since updating recently from a March 2016 build of OpenWrt, when this outage occurs, dnsmasq sends many messages, like this:
