Unbound notice: sendto failed: Permission denied
« on: January 12, 2018, 09:38:18 am »
I'm running 2.4.2-RELEASE-p1 (amd64)
I get ton of messages below in my resolver log if I enable Register DHCP leases in the DNS Resolver and Register DHCP static mappings in the DNS Resolver.

Jan 12 10:22:34   unbound   63108:3   notice: remote address is xxx.xx.xx.xx port 53
Jan 12 10:22:52   unbound   63108:3   notice: sendto failed: Permission denied

Name resolution seems to be working fine, although I could swear it's a bit slower now. I'm sure this is nothing to worry about, but I would like to understand what it's about. Also, having these constantly in the log hide actual events I would like to see. Should I just lower the verbosity? Would that make any difference?

EDIT: I cleared my proxy cache because I was getting a cache related error from squid for a specific site. After that, name resolution completely failed. I unchecked both Register DHCP and static options until that proves to be stable. I had to reboot pfsense because resolver didn't seem to even respond to an attempt at stopping the service, so restarting resolver alone was not an option.

I have same log entries in logs, but all seems works fine, I can't say clearly about performance because I have Windows DNS that actually give DNS to client and take it from pfSense and have many cache entries.
