I've configured a VPN connection and it created
foo interface listed with
ifconfig. Its IP is assigned via
From time to time, my connection drops. When I list the available interfaces with
ifconfig, there is
foo without an IP and
foo:avahi with a random IP.
If I request an IP with
dhclient foo, an IP (generally same IP) is immediately fetched, my internet connection is fixed and the
foo:avahi interface is disappeared.
What is this
...:avahi interface and how can I prevent this connection drops from happening?
