This is a collection of some commands to diagnose the DNS resolution problems, from OSX in a local network having linux and mac machines.

On linux, edit: /etc/avahi/avahi-daemon.conf to set 'use-ipv6' to 'no', so avahi resolves the hostname to ipv4 address. Not sure if this affects the DNS resolution from a mac, but I set it to ipv4 anyway.

use-ipv6=no

Restart avahi-daemon on linux:

sudo systemctl restart avahi-daemon.service

Resolve mDNS/DNS hostname to IP address and vice-versa:

avahi-resolve-host-name onizu-asus.local
avahi-resolve-address 192.168.0.110

Scan for mDNS/DNS-SD services published on the local network:

mdns-scan

on OSX, run the DNS Service Discovery tool:

dns-sd -E

The domain should be listed in the output of the above command. But for me it doesn't list anything..

A system reboot works for me. The local hostname starts resolving on the mac. Not able to figure out why it stops working after a while..
