<p dir="ltr">Matlab license required eth0. What a pain. Had to create a virtual device with a fixed MAC so Matlab would install even though it just used standard system network to contact Mathworks to register and get authorization key. Matlab 2016a fixed that (and broke a bunch of other stuff).</p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">The device naming for physical location in the system is separate from Network Manager itself and it requires the hardware to report the information. Personally
I like seeing the em# or p<slot#>p<port#> names because it helps me locate the NIC without having to run “ethtool –p”. One can use classic eth# names if preferred or if specific apps require it but so far I’ve not run across any that require the classic
names. In my view it is poorly written apps that insist on a specific naming convention that they don’t control rather than simply allowing one to specify the device name whatever it is. (In fact most apps shouldn’t even need the device name as they should
be relying on the IP or hostname setup rather than the device.) <u></u><u></u></span></p>

<p>Bunch of different ways. NetworkManager can now handle all the magic script-fu to handle everything from simple dhcp through redundant teaming with failover.<u></u><u></u></p>
<p>But the output is still ifcfg-fu scripts in /etc/sysconfig/network-scripts<u></u><u></u></p>
<p>The article doesn't mention that 7 uses pci bus name stuff like enp0s0f1 instead of eth0.<u></u><u></u></p>
