 |

After I did a system update I notice the following:
There is a delay in startup with an error message as follows:
successfully initialized wpa_supplicant
**delay occurs**
starting DHCP client daemon
caching netowrok module dependencies
need dbus
ERROR; interface eth0 does not exist
ensure that you have loaded the correct kernal module for your hardware
ERROR; net:eth0 fiaied to start
ERROR cannot start netmount as net.eth0 would not start
startup finally occurs and everything works normally including wifi
here is ifconfig -a

I am gentoo noob but I believe my network is based on emp0s25 and not eth0
I also do not think I am using wpa_supplicant for network access
So why am I getting this error message that is slowing startup and how do I make it go away? |

I had a similar issue to this but in reverse. My system lost all of its enp0s25 and enp6s0 network device names. They changed to eth0 and eth1 for some reason. I had been running for years using enp0s25 and enp6s0 but now have to refer to them as eth0 and eth1.
I switched the names in /etc/conf.d/net and created new runtime scripts for net.eth0 and net.eth1, added the to the default run level and then things were finally working well again.
Any ideas why I might have lost the use of enp0s25 and enp6s0? I update world and the kernel weekly and I didn't see anything mentioned in "eselect news list".
Thanks,
Perdignus |

Perdignus,
Is udev (or eudev) running?
The ethX names are generated by the kernel on a first come, first served basis.
During boot, your device manager renames ethX interfaces to something else.
This behaviour can be disabled but you would know if you had done that.

eklebanow,
You have Perdignus problem in reverse. :)
Something is trying to start eth0 but it doesn't exist. Its been renamed to enp0s25.
nick_gentoo is pointing the way.

NeddySeagoon,
Yup, looks like udevd is running:
ps aux |grep udev
root 3281 0.0 0.0 18344 7576 ? Ss 17:48 0:00 /sbin/udevd
equery b /sbin/udevd
* Searching for /sbin/udevd ...
sys-fs/eudev-3.2.9 (/sbin/udevd)
It was a bit of a pain and a nice panic to get networking working again but honestly I like eth0 and eth1 better than enp0s25 and enp6s0. It was fun to learn why they got names like enp0s25 and enp6s0 at first but always dificult for me to remember which was which on my system. eth0 and eth1 seem easier for me. Still a bit of a mystery to me why they would have changed though.
/etc/udev/rules.d/80-net-name-slot.rules does exist on my system too and I didn't do anything with "net.ifnames=0" to my kernel boot line.
Thanks,
Perdignus |
