Greetings;
My home network is all hosts based, but has a gateway and uses the router
as a relay to my ISP's nameservers for addresses not in the hosts file.
But I'll be switched if I can make it work that way on a pi-3b running
stretch.
When it needs to use a dns lookup, it sends the dns request from
picnc.local, which is of course the ahahi address, 169.254.etc.etc
Somehow, I need to convince this thing it only has one address!!!
My current /e/n/i.d/eth0 file:
-------------
auto eth0
iface eth0 inet static
address 192.168.71.12/24
gatewasy 192.168.71.1
dns-nameserver 192.168.71.1
search hosts dns-nameserver
hwadress 192.168.71.12
--------------
adding the hwaddress just now, and restarting networking did get rid of
the ahahi supplied lines in an ip a report so it looks like this but now
a second request shows they are back.
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast
state UP group default qlen 1000

And I have those 2 lines in /e/sysctl.conf that are supposed to shut off
the ipv6 stuff since I'm at least 100 miles from ANY ipv6 service.
/e/resolv.conf
nameserver 192.168.71.1
search hosts nameserver
But if I ping yahoo.com, this is what I get so of course it fails:
pi@picnc:/etc $ ping yahoo.com
PING yahoo.com (72.30.35.9) 56(84) bytes of data.

I has as much of avahi killed as systemd will let me but I can't kill it
all. That dns resolution for yahoo.com is correct, so that working fine
but it being sent from a wrong address the rest of this system knows
nothing about.
There is still an avahi (chroot helper) running. So how do I get rid of
the from hostname.local bs?
I can plug a raspian jessie u-sd card back into that pi, and it works
perfectly.
Thanks all.
i have always disabled avahi
never had a use for it
double check
systemctl status avahi-daemon.service
systemctl status avahi-daemon.socket
i have 6 pi's running various things around the house
