Hi all,
My network was ok once.
But after emerging the world recently, the network can't be used.

After check my dmesg, I find the suspicious message for my issue:
[ 28.020703] systemd-udevd[16767]: renamed network interface eth0 to enp2s1

Does the udev cause this problem?
Please help me to resolved it.

Hope these info are helpful to find the reason.

eth0 is a kernel name, and udev renamed it based on PCI geographical location to enp2s1. You forgot to rename the /etc/init.d/net.eth0 symlink to /etc/init.d/net.enp2s1 and perhaps you have put eth0 elsewhere too, like iptables?

Thank you very much!
It works.
Maybe I should study something about udev later.
