I have a question about the network and Centos 7 I am experimenting with two C7 installations: - On relatively new hardware, configured with fixed IP address in IPV4 only - on top of Windows, using VMWare, sharing my windows connection via Vmware's bridge with IPV4 only. On both configurations, I run a script every five minutes to test the network. The sequence is as follows: - Find the default interface using "ip route" - Find that interface's IP address by scanning the output of "ip route" for a match in interface. If the above tests fail to resolve, I issue "systemctl restart network", and post a mail message to myself. When this happens, the network does indeed come back correctly. I do the same sequence on Centos 6 installations, (using "system network restart"). I find that on Centos 6, I almost never get notified that the restart occurred (except when there's a real reason). On Centos 7, however, I find that about once a day or so, I get notified, even though there's nothing that has changed. On Centos 6, I left the avahi daemon running. On Centos 7, I disabled avahi (because with it enabled, I was getting this failure once every few hours). Are there any clues in the above? On C7, the "messages" log has nothing that I can associate with the failure. David
