    This article was helpful. I’m still adjusting to all the changes in v7 — the missing “setup” command to configure/modify basic network settings, the ifcfg-eth0 network configuration file was renamed to something else, and my trusty “service” command was replaced with “systemctl”.

    Not complaining, BTW. Having survived through several releases of AIX, Solaris, Redhat/CentOS, and spent time with Debian, Slackware, Caldera, heck even Xandros at one point, plus the always interesting *BSD flavors — largely I’m indifferent.

    I have installed CentOS 7.0 but “nmcli d” only gives me my lo lookback device, no Ethernet. I have installed Fedora 21 which uses basically the same interface and it finds my network card.

    For some reason it does not activate the network card so that it can be worked on.

    Any ideas?

    My network uses DHCP and when i try to resart or stop and start network.service it says:
    “Job for network.service failed. See ‘sytemctl status bla bla bla”
