On openSUSE 13.1 , dhclient eth0 works well, it re-request an IP address from DHCP server, which cost 1~2 seconds to finish.



dhclient on opensuse 13.1 works well



However, with openSUSE 42.3, dhclient always fails instantly. I don't know what is going on.



dhclient on opensuse 42.3 fails



It says sth like:



/sbin/dhclient-script: unable to pre-init requested interface eth0
/sbin/dhclient-script: unable to pre-init requested interfaces -- see log messages


And I don't know where to find that log messages.

  • and you should verify the interface name with ip link. It's perhaps not named eth0 anymore
