One Athena networking requirement is to set the DNS search domains to include .local. This is typically done by the DNS server. Where this is not possible, the search domains may also be added locally to each system.
1.Edit the /etc/systemd/resolved.conf file
sudo nano /etc/systemd/resolved.conf
2.Change the Domains line to read
3.Restart the systemd-resolved daemon
sudo systemctl restart systemd-resolved
