change.

Finally, I do an ifdown, followed by an ifup, and everything's wonderful.

My manager thinks that the NM daemon thinks everything's fine, and
there've been no changes, so it does nothing. He suggests that it might
have to be stopped, then started, rather than restarted.

This is completely unacceptable behavior, since it leave the system with
no network connection. Pre-systemd, as we all know, restart *RESTARTED*
the damn thing.

Is there some Magic (#insert "pixie-dust-sparkles") incantation, either
restarting NetworkManager, or using nm-cli, to force it to perform the
expected actions?

Btw, if this is supposed to be part of the "hide stuff, desktop Linux
users don't need to know this stuff", this is a *much* worse result.

there's a really good solution to this.

yum remove NetworkManager*

chkconfig network on

service network start

and yes thats all under fedora 25, and centos 7.

works like a charm.

sometimes removing NM leaves resolv.conf pointing to the networkmanager directory, and its best to check this, and replace your resolv.conf link with a file with the correct settings.

sorry if this upsets the people who maintain network mangler, but its inappropriate on a server.
