Hi all,
I am having a major problem on one of my systems with a network controller.
The system has the Intel DQ77MK motherboard. This board has dual NICs. The first NIC, an Intel 82574LM works fine and is called eno1 The second NIC, an intel 82574L is the problem.
The second NIC is called rename3, or sometimes rename2 / rename6 or rename7 etc.. It keeps changing.
Whenever I try to apply any configuration to this NIC it changes name again, therefore I have no network connection. So I change the name in the config and the NIC changes name again.
I have never seen a NIC called rename before. What is this trickery?!?!?
This is Debian specific patch. Number is kernel interface index. "rename%u" is supposed to be temporary until interface got renamed to final name.
The system is running ubuntu 18.04. Now I have probably confused you by posting on the OpenSUSE list, but the fact is I have posted on the Ubuntu forum and it has been 4 days and I have had no reply what so ever. It is still Linux after all, so hopefully one of you might be able to assist?
Streetlight effect ...
Ubuntu 18.04 uses netplan to manage the network configuration. I intend to set up an bond in balance-rr mode as I have done on another system without issue.
How can I go about diagnosing this?
I usually start with checking logs. udev fails to rename interface; logs should contain error message with error number (or error string) which may give some starting point. Booting with "debug" on kernel command line (or enabling it specifically for udevd) could be helpful too.
This is the first time I have every had a NIC not work in any linux distro (apart from broadcom wifi drives cough cough..) so I have literally no in-depth knowledge of networking in linux.
so basically... HELP! lol
First things I checked:
