A tentativa de concessão de IP do DHCP falhou na Ethernet e no DHCP com o netctl

3

Minha Ethernet DHCP funciona bem no Windows, mas não no Arch Linux com netctl e dhcpcd . O que estou fazendo errado?

Saída de ip link

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: wlp2s0: [...]
3:  eno1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether [my mac adress] brd ff:ff:ff:ff:ff:ff

Meu netctl profile

$ cat /etc/netctl/dhcp
Description='ethernet dhcp'
Interface=eno1
Connection=ethernet
IP=dhcp
#IP6=dhcp
#IP6=stateless

Mensagem de erro após sudo netctl start dhcp

$ sudo journalctl -xn
-- Logs begin at Fr 2013-12-27 13:25:36 CET, end at Mo 2014-01-13 12:45:22 CET. --

OK, então, tem problemas para organizar a rede, fazer isso sozinho ...

$ sudo ip link set eno1 up
$ sudo netctl start dhcp
Job for [email protected] failed. See 'systemctl status [email protected]' and 'journalctl -xn' for details.
$ sudo journalctl -xn

Jan 13 12:47:20 laptop2 systemd[1]: Failed to start Networking for netctl profile dhcp.

Isso também não ajuda, definindo-o novamente.

$ sudo ip link set eno1 down

Tentando com dhcpcd ...

$ sudo systemctl start dhcpcd
$ ping www.google.de
connect: Network is unreachable
$ ip link
[...]
3: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000

$ sudo systemctl stop dhcpcd

$ sudo netctl start dhcp

Depois de excluir a concessão em /var/lib/dhcpcd/dhcpcd-eno1.lease6 e tentar novamente, recebo a mesma mensagem de erro. Escrever TimeoutDHCP=40 para /etc/netctl/hooks/timeout e torná-lo executável também não muda nada.

Solved

The network cable was defective.  I switched it out and it works again.
