Systemd no internet
I have a systemd intallation and i have followed the systemd net setup guide so i created the file in the networkd directory for a dhcp connection and i have enabled the service. I have also created the symlink for dns and i also enabled that. I still do not have internet. Ip a shows my lan state is UP but still nothing. If i remember correctly i also installed dhcpcd. I have also created a symlink in init.d for the net interfaces since at first i didnt realise that that is for openrc only. How can i delete those symlinks? Will it break anything if i do? Do i need to do something else for the network to work? |

Hi i hope you have a file like
/etc/systemd/network/eth0.network
| Code: |
### for dhcp
[Match]
Name=eth0
[Network]
DHCP=yes
###for static
[Match]
Name=eth0
[Network]
Address=10.1.10.9/24
Gateway=10.1.10.1
DNS=10.1.10.1
|
Either use dhcp or static.
And comment out the other.
What is the name of your iface?
Please Do NOT manually create any symlinks.
| Code: |
emerge -av dhcpcd
rm /etc/resolv.conf
echo "nameserver 8.8.8.8" > /etc/resolv.conf
systemctl enable --now dhcpcd
systemctl enable --now systemd-networkd
|
If it doesnt work with dhcp use static.
Can you bring up your iface?
| Code: |
ip link set <iface> up
ip a
|
If not you miss kernel .config
I am not sure if Gentoo implementation of systemd has also systemd-resolved or no.

i created the file in the networkd directory

The directory should be
| Code: |
/etc/systemd/network
|
NOT "networkd"

| Well ip a has my ethernet interface named ens60u1 or something like that but i use a usb to rj45 adapter. The interface gets renamed to eth0 so im not sure which one to put there. Yes i have that file although only the dhcp part. One more question, about the *nameserver*; is that literal or what should that name be? |

Please get rid of the obnoxious enp0hhuhhuhu naming.
I know its very confusing
In
/etc/default/grub
please
| Code: |
GRUB_CMDLINE_LINUX="................ net.ifnames=0 biosdevname=0"
grub-mkconfig -o /boot/grub/grub.cfg
reboot
|
You will now have eth0 and eth1
If you need both create two files in
/etc/systemd.network
one et0.network and another eth1.network
NOT BOTH DHCP
Keep eth1 static WITHOUT assigning any "Gateway="
Have i understood correctly?
You have 2 ethernet ifaces no?
