    Default Network connection Problems (Hardware/Driver ? ) Opensuse Leap 15

    Hello,
    i have Problems to connect my Opensuse Leap 15 Installation to a company network. I dont get a IP Adress via DHCP , when i assign a IP Adress manually, i get no connection. Other distributions (Ubuntu, Windows7) get a connection with the same configuration.
    Code:

    I tried to install a different driver for the intel e1000e, but it failed because of missing kernel headers.

    Can you please help?

    Obscuring your private IP address is unnecessary. If you assign a static IP address, you also need to manually assign a default route to gain internet connectivity, and configure a valid name server as well for name resolution (via DNS) to work.

    Don't do that. The existing kernel driver is all that is required.

    You should post the output of the following....
    Code:
    ip a
    Code:
    ip r
    You mention that DHCP didn't work as expected. Are you using wicked (configured via YaST) or NetworkManager (configured with connection editor, but a DHCP ethernet connection should work out of the box)?

    Hi,
    my problem is not the internet connection. Even when i assign manual ip-adresses i can not ping the computers in the same subnet (10.49.120.177).



    Still static ip config:
    Code:
    1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
        link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
        inet 127.0.0.1/8 scope host lo
           valid_lft forever preferred_lft forever
    2: em1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
        link/ether 98:90:96:b2:91:d5 brd ff:ff:ff:ff:ff:ff
        inet 10.49.120.169/24 brd 10.49.120.255 scope global em1
           valid_lft forever preferred_lft forever
    ip r

    The not working dhcp seems not to be my problem as i can not ping or reach anything in my network with manual ip adress.
    I tried both Network Manager and wicked , with dhcp as well as with static ip.

    When i boot ubuntu and windows 7 on the same machine with same configuration, i am able to ping other computers or get a dhcp adress.

    does anyone know what "drv probe link" means ?

    I can only suggest that you have assigned an IP address (10.49.120.169/24) in the wrong subnet for your LAN then.

    To check DHCP process manually...

    Watch the journal (assuming /var/log/journal/ directory exists)...
    Code:
    sudo journalctl -f
    or if using rsyslog/syslog-ng
    Code:
    tail -f /var/log/messages
    then in another terminal run
    Code:
    sudo dhclient em1
    and watch/capture the output generated.

    What happens after the above? I feel like it's not showing the whole picture.

    It might be useful to watch the wicked logging for a longer period, or perhaps examine the wicked.service logging with
    Code:
    sudo systemctl -u wicked
    Clearly though the static IP address gets assigned. What you haven't demonstrated/verified is that it's the correct subnet for the network you're trying to connect to. Is it really /24 net for example?

    With a DHCP configuration, open a terminal and do
    Code:
    # journalctl -f
    In another terminal do
    Code:
    # ifdown em1;ifup em1

    as i told u before, i have on the exact same maschine ubuntu (18.04)running.
    With the exact same configuration i get a valid adress via dhcp, can assign my adress with the same subnet manually and ping other maschines.

    I note from reading the openSUSE 15 release notes, there was some mention of changes relating to DHCP...
    https://doc.opensuse.org/release-not...wicked-rfc4361
    ...but I'm not sure of the significance of this and whether you're impacted by these changes perhaps...
