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.
If you are using fixed IP addresses, how is this check supposed to detect network failures? Actually I'm surprised that it's failing sometimes, as it should be pretty static.
If that test is really that way, I would recommend saving those outputs for post analysis because the shouldn't be changing like that. Like, instead of ip route | grep, save it to a file using a known timestamp, grep on it and leave it there/mail it to you if it fails.

Of course, now that I stare at my environment, have 'avahi' and 'network manager' turned off, the failure does not show up. So, I withdraw the problem.
