Dnsmasq troubleshooting

Steps in troubleshooting the new dnsmasq setup in Amahi 7.

1. Check what is in /etc/resolv.conf.
   • There should be three lines, something like search YOURHOMEDOMAIN and two with nameserver IP (where IP is the internal IP of your HDA)
   • If that is not right, then try restarting hda-ctl, as root and check again: systemctl restart hda-ctl.service
2. See if dnsmasq is running with ps guax | grep dnsmasq
   • You should see a line like this: nobody ..... /usr/bin/dnsmasq (where instead of dots you see numbers and a time/date)
   • If it's not running for some reason, try restarting it as root with: systemctl restart dnsmasq.service
3. Check the dnsmasq configuration files in /etc/dnsmasq.d
   • There should be at least three files there: amahi-common.conf, amahi-dhcp.conf and amahi-dns.conf
4. There should be some settings in them and they should not mentioned that a service (DNS or DHCP) is not enabled
5. In the DNS file, there should be two server lines, with an IP, like this: server=208.67.222.222
   • Make sure you can ping those two IP addresses. If not, you have an issue with your routing ... perhaps you cannot reach your router from your HDA?
6. Your router address should be in the amahi-dhcp.conf file, in a line like this: dhcp-option=option:router,192.168.1.1
   • Make sure the address of your router is proper there

If these configuration parameters are not right, please access your HDA dashboard and access Setup > Network and change accordingly.
