Who misses the old Linux Ethernet names? Remember when your network interfaces were just eth0 and eth1? Now we have long names like enp0s25. Let's see where you stand.

@nixCraft@mastodon.social I always start looking for eth0, then remember it‘s gone for whatever reasons and fuck around to find the new name which my brain then instantly forgets again.

@nixCraft@mastodon.social I'm a multi-decade user of Unix, BSD, and Linux which means I'm nostalgic for ethX naming, but at the same time I understand the need for deterministic naming of interfaces (Checkpoint firewall admins know /exactly/ what I'm talking about - there's a kb that talks you through pinning this MAC to that interface name).

So I'm conflicted. I prefer the old naming standard, but appreciate the new way means that interfaces don't "move around".

Not a fan of Linux distributions getting rid of ifconfig/arp/netstat though.

@nixCraft@mastodon.social There's a boot parameter you can put in your bootloader that replaces those long names with the older names. I use this boot parameter.

The parameter in question is "net.ifnames=0". If you're using GRUB, put it under "GRUB_CMDLINE_LINUX".

@nixCraft@mastodon.social My question is, why do we have those overcomplicated names for ethernet interfaces?

@nixCraft@mastodon.social I miss it, but the new names are better.

@odysseywestra@linuxrocks.online @nixCraft@mastodon.social I believe it was so they were deterministic based on bus/slot location . Plugging in a new device could have reordered eth0,eth1. But the new naming “fixed” that.
