 |
|
Hi,
I just set up a new gentoo box.
Unfortunately I don't have an internet connection with my fresh installation after booting the system.
/etc/systemd/network/50-dhcp.network
| Code: | [Match]
Name=enp3s0
[Network]
DHCP=yes
|
output of "ifconfig -a" looks like this:
| Code: | enp3s0: flags=4098<BROADCAST,MULTICAST> mtu 1500
ether xx:xx:xx:xx:xx:xx txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
device memory 0xa1b00000-a1bfffff
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
loop txqueuelen 1000 (Local Loopback)
RX packets 4 bytes 416 (416.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 4 bytes 416 (416.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
|
But the interface on enp3s0 doesn't work.
"journalctl -b -u systemd-networkd.service" shows this:
| Code: | -- Journal begins at Tue 2021-10-12 21:16:55 CEST, ends at Mon 2021-11-08 22:09:47 CET. --

Nov 08 22:08:10 pcgrz-gentoo2 systemd-networkd[1345]: enp3s0: Failed
|
Obviously I'm missing something, but even after reading the installation guide multiple times I can't figure out what it is.
Especially this confuses me:
| Code: | | Nov 08 22:08:10 pcgrz-gentoo2 systemd-networkd[1345]: enp3s0: DHCP4 CLIENT: Failed to set IAID+DUID: No such file or directory |
What file or directory is missing?
Thanks for any hint!

The error refers to values found in
/etc/systemd/networkd.conf
Does
| Code: |
systemd-machine-id-setup
|
help?
If you are stuck you might wish to give it a static ip,which is preferable if you are using your machine in your home LAN
| Code: |
[Match]
Name=enp3s0
[Network]
Address=192.168.1.11/24
Gateway=192.168.1.1
DNS=1.1.1.1
|
for example
Remember to enable it.

ahlx,
In your messages it seems to me it missing enp3s0: link is up. So is your ethernet cable plug in? may be change a different cable to try? |

Hi pingtoo, thanks for your hint.
Of course I checked physical connection from my PC to the router.
Booting with the installation disk an internet connection was available.
It was only missing in my fresh installation

Hi alamahant,
yeah, that's it.
After "systemd-machine-id-setup" the network started up and I got internet connection.
Thanks a lot
