DHCP enabled , disabled

Iznobe_D · November 5, 2019, 10:11pm

Hi ,

before installing pi-hole i had configured a basic DHCP server .

after installing pihole , i gone to the paramaters and i activated the DHCP server built-in .
this is not working with my bridged wifi <=> lan , so i decided to desactivate the built-in pi-hole DHCP server .

and at this point , the config file is empty ...

you should save file /etc/dnsmasq.conf before modifying it ... and restaure the saved file after user desactivate the DHCP server include on pihole ...

This is a good practice for any file you modify.

Edit - you shouldn't be changing this particular file - see comment below.

Changes are made to files in /etc/dnsmasq.d and not to the main /etc/dnsmasq.conf file.

Hello ,

the main file /etc/dnsmasq.conf is deleted and then it is set to a link to the dnsmasq.d directory …

so the /etc/dnsmasq.conf file is not as before install DHCP server …

why i tell this if it is not true . try and see please .

Regards.

here is the new content of /etc/dnsmasq.conf :

pi@rasphomfi:/ $ cat /etc/dnsmasq.conf
conf-dir=/etc/dnsmasq.d
pi@rasphomfi:/ $

before install and / or activate pi-hole DHCP server built-in the content was :

 pi@rasphomfi:/ $ cat /etc/dnsmasq.conf
interface=br0
except-interface=wlan0
dhcp-range=192.168.1.12,192.168.1.254,255.255.255.0,24h
server=9.9.9.9
domain-needed

/etc/dnsmasq.conf is checked prior to installation. If it is ours then it is backed up, if it is not then it is left alone.

To verify, run the installer as sudo bash -x and you can see the steps taken, you should see the text

Existing dnsmasq.conf found... it is not a Pi-hole file, leaving alone!
