Re: kolev: nsd: error: can't bind udp socket

Greetings Kolev,

Take a look at that error message:

192.0.2.53@53: Can't assign requested address                                   

Check /var/nsd/etc/nsd.conf

Somewhere you're using 192.0.2.53 as your IP address, but you should be
using 104.167.242.174.
