What makes ens33 more absurd than eth0?

Sometimes tradition is wrong for modern things.

Eth0 is easily recognizable by all familiar with traditional networking, without eidedic memory, and without requiring a lookup table. Maximum predictability here means every installation under the same roof uses the same name for the first (and only) *E*T*H*ernet port for it's reserved IP address.

By default systemd now names interfaces using firmware/BIOS provided index numbers (e.g. eno1), but if that info is not available (possibly because you're inside vmplayer) it falls back to naming after firmware/BIOS provided PCI-E hotplug slot index numbers -- which is what you're seeing here.

It's in order to ensure *predictable* NIC names across reboots.

My computers have been reliably using eth0 for decades. This computer has two nics, and eth0 has always been eth0, and eth1 has always been eth1. For instance, now a script that used eth0 would have to be edited for each computer.

How would one make reference to the third Ethernet interface in a box that has five? You have to call it something, and changing the name without good reason sounds like something for-profit operating systems would do. Or, are you saying that we should never need to refer to a network interface by name? That referring to it by IP address should be enough? But what about interfaces without IP addresses, such as /dev/rst0? Wouldn't it be possible to make the "ethX" names predictable across reboots? Or am I missing something?

The point is that any name (network interfaces or device nodes) could already be a name that the user has statically assigned overruling any default system decisions.
But what about interfaces without IP addresses, such as /dev/rst0?
Since no single identifier works for all people in all cases, that is why there is the possibility to pick them out in multiple ways. Serial number, Make&Model, PCI/USB "path", ...

Yes, define some static user-endorsed rule like those the systems has so far (in openSUSE) created for us in 70-persistent-net.rules. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

No, I am not. what I'm trying to say is that there must be a simple way to determine the needed interface name dynamically.

Thanks, that does make sense. I still remember the SunOS 3.3 days where SCSI disks and tapes were named according to their SCSI bus addresses, which were hardware switch selectable. At some point after that the notion (from the Pea Sea world I think) that hardware addressing should be randomized at boot was introduced. Boy, did THAT ever suck!

Further on this. The computer with 3 NICs is my firewall. It has a built in NIC and I added 2 more NICs. As originally configured with the 3 NICs., the plug in NICs were eth 0 & 1 and the built in one eth2. I later removed eth1, because it was failing. But doing that did not cause the other NIC IDs to change. I now have eth0 and eth2, with no eth1 in the computer at all. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

The other 2 boxes still had /etc/udev/rules.d/70-persistent.net present. Yes, on an update you should definitely be able to retain the existing naming. I suggest you open a bugreport.
I shall leave as is for now as I created /etc/udev/rules.d/70-persistent.net on the one box where it was missing, subsequent updates have not changed it. Regards Sid. -- Sid Boyce ...

Where is eth0? Why the change? How do I revert that change?

Somwhat tangential to Carlos' question here, but any chance that anyone would want to take a look at https://bugzilla.novell.com/show_bug.cgi?id=842450 The networking naming isn't exactly consistent. Sometimes something is renamed, sometimes not. -- Per Jessen, Zürich (16.1°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
