[SOLVED]Wired network works from Installer-USB-Stick, but not from HDD

Hello,

I've installed Archlinux on my MacBookPro11,3 and the wired network connection worked without any problems directly from the Installer-USB-Stick as described in the MacBookPro11,3 Wiki-entry. After rebooting the wired connection does not work any more and I can't find an error message because the screen is cleared after the boot process. Is there a difference between the Stick and the actual install (I followed the guides in the wiki). Can I check somehow what does not work correctly? Is there a command to show network error messages not only at booting?

Thanks for your help
Jens

Have you tried:

# systemctl start dhcpcd
# systemctl enable dhcpcd

If that doesn't work, post the output of:

ls -l /etc/systemd/system/multi-user.target.wants

EDIT: For error messages, see: https://wiki.archlinux.org/index.php/Systemd#Journal

Should be

# systemctl start dhpcd@interface.service

Enabling dhcpcd for all interfaces will cause a race condition with udev.

Re: [SOLVED]Wired network works from Installer-USB-Stick, but not from HDD

Hello,

ok I have done the following from my Installer-USB-Stick and from my HDD-Install. Both produce the same output:

#ip link
1: lo <LOOPBACK,UP,LOWER_UP> ...
2: ens9: <BROADCAST,MULTICAST> ...

On my Installer-USB-Stick the wired connection directly works. So I tried to enter your commands when I boot from HDD:

#systemctl start dhcpd
Failed to start dhcpd.service: Unit dhcpd.service failed to load: No such file or directory.

#systemctl start dhcpd@ens9.service
Failed to start dhcpd@ens9.service: Unit dhcpd@ens9.service failed to load: No such file or directory.

So I tried the second command you gave me:

#ls -l /etc/systemd/system/multi-user.target.wants
insgesamt 0
lrwxrwxrwx 1 root root 40 30. Aug. 19:22 remote-fs.target -> /usr/lib/systemd/system/remote-fs.target

what means a total of 0 in english.

So do you have any idea what's wrong with this?

Thanks a lot for your help
Jens

#systemctl start dhcpd@ens9.service

You have entered the wrong .service name -- it should be "dhcpcd"
