Interface setting

Andi17 · January 2, 2022, 6:23am

Hello together,

I have an questtion to the Interface setting.

I reinstalled my PiHole, because the recommend setting wasn't possible to Set.

My question ist now why is the setting"responed only on interface eth0" set AS Default after Installation and not the "recommend - allow only local requests" setting?

Thanks in advance

I think you are right. We changed the web interface but not the installer script.
We do export the listening interface to setupVars.conf

github.com/pi-hole/pi-hole

automated%20install/basic-install.sh

1b809e4e8


      
              fi
          fi
          
          # If the setup variable file exists,
          if [[ -e "${setupVars}" ]]; then
              # update the variables in the file
              sed -i.update.bak '/PIHOLE_INTERFACE/d;/IPV4_ADDRESS/d;/IPV6_ADDRESS/d;/PIHOLE_DNS_1\b/d;/PIHOLE_DNS_2\b/d;/QUERY_LOGGING/d;/INSTALL_WEB_SERVER/d;/INSTALL_WEB_INTERFACE/d;/LIGHTTPD_ENABLED/d;/CACHE_SIZE/d;/DNS_FQDN_REQUIRED/d;/DNS_BOGUS_PRIV/d;' "${setupVars}"
          fi
          # echo the information to the user
          {
              echo "PIHOLE_INTERFACE=${PIHOLE_INTERFACE}"
              echo "IPV4_ADDRESS=${IPV4_ADDRESS}"
              echo "IPV6_ADDRESS=${IPV6_ADDRESS}"
              echo "PIHOLE_DNS_1=${PIHOLE_DNS_1}"
              echo "PIHOLE_DNS_2=${PIHOLE_DNS_2}"
              echo "QUERY_LOGGING=${QUERY_LOGGING}"
              echo "INSTALL_WEB_SERVER=${INSTALL_WEB_SERVER}"
              echo "INSTALL_WEB_INTERFACE=${INSTALL_WEB_INTERFACE}"
              echo "LIGHTTPD_ENABLED=${LIGHTTPD_ENABLED}"
              echo "CACHE_SIZE=${CACHE_SIZE}"
              echo "DNS_FQDN_REQUIRED=${DNS_FQDN_REQUIRED:-true}"

And then call the webscript

github.com/pi-hole/pi-hole

automated%20install/basic-install.sh

1b809e4e8


      
          # Look for DNS server settings which would have to be reapplied
          ProcessDNSSettings

But do not set/export DNSMASQ_LISTENING
required

github.com/pi-hole/pi-hole

advanced/Scripts/webpage.sh

1b809e4e8


      
          
          # Setup interface listening behavior of dnsmasq
          delete_dnsmasq_setting "interface"
          delete_dnsmasq_setting "local-service"
          delete_dnsmasq_setting "except-interface"
          delete_dnsmasq_setting "bind-interfaces"
          
          if [[ "${DNSMASQ_LISTENING}" == "all" ]]; then
              # Listen on all interfaces, permit all origins
              add_dnsmasq_setting "except-interface" "nonexisting"
          elif [[ "${DNSMASQ_LISTENING}" == "local" ]]; then
              # Listen only on all interfaces, but only local subnets
              add_dnsmasq_setting "local-service"
          else
              # Options "bind" and "single"
              # Listen only on one interface
              # Use eth0 as fallback interface if interface is missing in setupVars.conf
              if [ -z "${PIHOLE_INTERFACE}" ]; then
                  PIHOLE_INTERFACE="eth0"
              fi

Thanks for your fast reply, But i'm not so good in Reading Scripts

This means that the Installer script need to be updated?

Thanks in advance
