Hello all!
A couple of days ago I switched from an Asus AC66u to a Fujitsu S930 thin client running OPNsense 20.1 and it is working perfectly!
I am wondering about something I noticed in the logs.
Under System - Log Files - General I see the following:
2020-03-31T16:23:36 dhclient: Creating resolv.conf
2020-03-31T15:53:36 dhclient: Creating resolv.conf
2020-03-31T15:23:36 dhclient: Creating resolv.conf
2020-03-31T14:53:36 dhclient: Creating resolv.conf
2020-03-31T14:23:36 dhclient: Creating resolv.conf
2020-03-31T13:53:35 dhclient: Creating resolv.conf
Every 30 minutes it seems to recreate resolv.conf
resolv.conf contains the following:
domain lan
nameserver 127.0.0.1
nameserver 1.1.1.1
Is this normal behaviour or is something wrong?
I never noticed this in the Asus logs.
My connection is a T-Mobile FTTH connection and I use a TP-Link MC220L to convert fiber to ethernet.
In System - Settings - General I have set the DNS to 1.1.1.1
'Allow DNS server list to be overridden by DHCP/PPP on WAN' is unchecked (same result when this option is checked).
All clients use my pi-Hole for DNS resolving.
I'm still a noob, so please be gentle :)
did u ever reach any conclusions on this?
Does your WAN connection use DHCP? If so, you probably have a 30min lease time, which causes resolv.conf to be recreated on each lease renewal.
