Hi,

I have an embedded target (musl) that I need to mdns resolution. I built avahi2mdns and deployed it successfully. I added a nameserver 127.0.0.1 entry to resolve.conf but when I attempt to ping a .local address from the embedded target ping fails. Interestingly, avahi2dns seems to do its job correctly however. Any idea what could be causing this? Log below.

Thanks!

Hi @mattwood-microchip,

Weird, everything seems to be working...

What's the output of dig in that scenario?
