I don't claim that the packets are not being sent, but rather that the
system does not work as expected out of the box when it did in a
previous LTR. I don't really care what package is the cause except to
help get the problem fixed. I have done as much debugging of this as I
am capable since
I have checked iptables and there are no rules.
# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt
Before I get a chance to look into this later today, I'd like to note
that the network device is not firewalling those packets since a few
days ago before I installed 18.04 on this machine it was behaving as
expected and the 16.04 machine mentioned in the OP is not being blocked
(it is on a
The most likely cause for this is that you have packets outbound on port
5353 firewalled either locally or on your network device. When another
host pings the address, the responses are sent via multicast and Avahi
caches that response, and so can then use it without having to transmit
a packet.
