unable to add default route

English Network/Internet
1

Hi, i am new here

currently running leap on my lenovo T410, it runs well except sometimes i got blank screen follow by shutdown.
well not big issue for me…

I want to build home server using leap, no problem with installing.

i setup dhcp via YasT. i plugged on LAN cable then i got nothing from dhcp server.
i tried to reboot pc, re setup dhcp server on router, still pc didn’t receive IP from server.

at first i disable NM, use wickedd, then i switch to NM, still dont get Ip

i tried to add default route manual from konsole

route add default gw 192.168.2.1 eth0

and voila i got ip, default route and have internet access
but when pc reboot, the default route went missing, it went back to default with no ip and default gateway

btw i bought 1 new motherboard, i thought its hardware issue, now i think its not related to motherboard

here networkmanager status before i manual add default route

ruko:/etc/NetworkManager # systemctl status NetworkManager

This, as well as your journalctl output, seems to indicate that the
correct gateway IP is 192.168.2.1, and while that sounds fine, I also see
attempts to add 192.168.1.0 as your gateway address, which is definitely
wrong if you are using a /24 netmask as that is the network address.

The question is, “Why is anything trying to use 192.168.2.0?” To me, the
most-obvious answer is that your DHCP service is misconfigured and trying
to send out that address, though that is really odd since most home setup
(maybe this is not your home) have the router and DHCP service in one, and
they know how to advertise their one internal IPv4 address as a gateway
via DHCP, so unless you manually tweaked something, or you have a separate
DHCP service that you setup, this should not be the case. Perhaps you can
shed some light on that, though.

Another way to verify this may be to use tcpdump to show what the DHCP
service is offering:


sudo zypper in tcpdump
sudo /usr/sbin/tcpdump -n -s 0 -i any -v port 67 or port 68

Let it run for a bit as you restart Network Manager and hopefully we’ll
get some useful information. We are looking for a Reply, kind of like this:

From the systemd Journal, you have “Wicked” enabled – which is IMHO a correct decision for the case of a Desktop and/or Server system.

“Network Manager” on the other hand is, IMHO, the correct decision for Laptops and other mobile/portable machines.

Be aware that, “Wicked” and “Network Manager” are mutually exclusive – use one or the other but, not both . . .
For example, on this Desktop machine:


 > systemctl list-unit-files | grep -E 'Network|icked'
dbus-org.opensuse.Network.AUTO4.service enabled
dbus-org.opensuse.Network.DHCP4.service enabled
dbus-org.opensuse.Network.DHCP6.service enabled
dbus-org.opensuse.Network.Nanny.service enabled
NetworkManager-dispatcher.service       masked
NetworkManager-wait-online.service      masked
NetworkManager.service                  masked
wicked.service                          enabled
wickedd-auto4.service                   enabled
wickedd-dhcp4.service                   enabled
wickedd-dhcp6.service                   enabled
wickedd-nanny.service                   enabled
wickedd-pppd@.service                   static
wickedd.service                         indirect
 >

For Laptops the systemd enabled/disabled is the other way around: “Network Manager” is enabled and “Wicked” is disabled.

appreciate the reply ab
it turns out, i put wrong gateway ip like you said “why is anything trying to use 192.168.2.0?”
so i re-check closely on my router dhcp setup, i put 192.168.2.0 on gateway box, feel so stupid cause i have check this setup couples time, i did not see anything wrong with the setup.

so now dhcp is working, i change from static ip to dhcp at my desktop pc.
i am able to remote via ssh.

thanks again ab

i am aware with this condition, everyone suggest to use wickedd over NetworkManager…
thanks anyway.
