--- title: Reboot --- Dealing with issues related to power failures or network node reboots. # DNS ## Cannot resolve address of media node after power failure Symptom : Can't ping or lookup hostname (e.g. 'pixie') Further Symptoms : Airplay cannot connect. Usually to the battery powered devices like tablets. Cause : Node boots before [Perimeter Router][1] DNS service is ready. Further Causes : OpenWRT dnsmasq leases file is scrubbed by a reboot. Network nodes typically resume the lease they held before the power failure. Since dnsmasq has no record of the lease it cannot resolve the hostname. Fix : Create barebones `/etc/network/interfaces` and `ifup` it. [1]: PerimeterRouter <!-- vim: filetype=markdown -->
