      on my Dell machine with an internal Ethernet chip this chip is found on eth0. However, it is changed later during the boot procedure to eth1.
      In /var/log/messages I found the lines

      Apr  1 19:20:01 dell kernel: [    6.849098] input: HDA Intel PCH Front Headphone as /devices/pci0000:00/0000:00:1b.0/sound/card0/input12
      Apr  1 19:20:01 dell kernel: [    6.894285] e1000e 0000:00:19.0 eth1: renamed from eth0
      Apr  1 19:20:01 dell kernel: [    7.454245] fb: switching to nouveaufb from simple
      

      Later on I get an error message by the DHCP client that eth0 could not be found.
      I had to set the LAN port to eth1 in wicd and this way I get internet access.
      So it’s not really I problem for me, but the error message from the DHCP client is irritating.

      I searched the web for a solution and I thought it is a udev issue.
      However, my /etc/udev/rules.de/70-persistent-net.rules contains

      # This file was automatically generated by the /lib/udev/write_net_rules
      # program, run by the persistent-net-generator.rules rules file.
      #
      # You can modify it, as long as you keep each rule on a single
      # line, and change only the value of the NAME= key.
      
      # PCI device 0x10de:0x0269 (forcedeth)
      SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:19:99:15:b9:07", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
      

      My question : is it save to remove the KERNEL=="eth*"
      entry and is it indeed the solution for the issue ?

      Note : I moved the hard disk with already installed antiX17 from another PC to the Dell. Is this the reason for the renaming ?

        Yes.

        That’s exactly what I tried to explain here:

          delix02, here’s a snippet found via websearch which explicitly answers
          is it save to remove the KERNEL==”eth*” entry and is it indeed the solution for the issue ?

          it’s best to remove the KERNEL=”eth*” part of your rules otherwise they will not apply in cases where, during boot, the kernel gives a name that is not like eth* to an interface (in my case it was p9p1. I removed the KERNEL constraint and the rules got applied as expected).

            thx for the answers !
            I’ll give it a trial.

            is the discussion I found, but I guess it is a bit of a “unfinished business”

              (in my case) the removing of the “KERNEL==eth0” entry didn’t help. No changes.

              I had to remove the whole rule file. The next boot process created a new one with the correct ID for the Dells’ eth interface.
