Custom hostnames on /etc/hosts not resolved

Question

I've added a few hostnames in /etc/hosts to resolve to my LXD container:

$ less /etc/hosts
127.0.0.1       localhost
127.0.1.1       HOST
lemh            10.0.3.219
pma.lemh        10.0.3.219
wp.lemh         10.0.3.219

But ping, getent ahosts or Firefox cannot resolve them. I don't want to restart right now.

I've tried systemctl restart networking.service to no avail. Is there a way to resolve them without restarting my system?

Answer 1

in /etc/hosts you have to write:

ip alias

so the correct form is:

127.0.0.1       localhost
127.0.1.1       HOST
10.0.3.219 lemh pma.lemh wp.lemh
