Eu tenho uma placa / cabo Ethernet com fio para o meu hub. Eu inicio o Fedora 23 mas não há rede , por quê? Então, verifiquei se o cartão existe: -
[root@localhost ~]# lspci | grep Ether
00:0b.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8100/8101L/8139 PCI Fast Ethernet Adapter (rev 10)
[root@localhost ~]# lspci -vm -s 00:0b.0
Device: 00:0b.0
Class: Ethernet controller
Vendor: Realtek Semiconductor Co., Ltd.
Device: RTL-8100/8101L/8139 PCI Fast Ethernet Adapter
SVendor: Packard Bell B.V.
SDevice: Device e012
Rev: 10
Então eu tento iniciar a rede (fyi systemctl restart network.service tem a mesma saída) ...
[root@localhost ~]# service network start
Starting network (via systemctl): Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details.
[FAILED]
O resultado do comando sugerido ( systemctl status network.service acima) é ...
[root@localhost ~]# systemctl status network.service

Então me deparei com algumas sugestões aqui que eu verifiquei o conteúdo de scipts de rede e ifcfg-enp0s11 , o que falhou acima parece ser o que eu estou procurando, o MAC endereço é o mesmo que o listado em ifconfig -a para esse dispositivo nomeado
[root@localhost ~]# more /etc/sysconfig/network-scripts/ifcfg-enp0s11
HWADDR=00:13:D4:86:EB:18
TYPE=Ethernet
BOOTPROTO=dhcp
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=enp0s11
UUID=b7fce5e7-b3aa-4e95-a014-8661889e9cce
ONBOOT=yes
Minhas outras opções em scripts de rede foram
ifcfg-enp0s11 ifdown-ippp ifdown-routes ifup ifup-ipv6 ifup-ppp ifup-tunnel
ifcfg-lo ifdown-ipv6 ifdown-sit ifup-aliases ifup-isdn ifup-routes ifup-wireless
ifdown ifdown-isdn ifdown-Team ifup-bnep ifup-plip ifup-sit init.ipv6-global
ifdown-bnep ifdown-post ifdown-TeamPort ifup-eth ifup-plusb ifup-Team network-functions
ifdown-eth ifdown-ppp ifdown-tunnel ifup-ippp ifup-post ifup-TeamPort network-functions-ipv6
Mas ifup eth , ifup eth1 , ifup eth2 , ifup enp0s11 e ifup lo todos dizem que não foi encontrada nenhuma configuração ?!
[root@localhost ~]# ifup eth
/usr/sbin/ifup: configuration for eth not found.
Usage: ifup <device name>
Entendo parcialmente que os comandos ifup não são mais usados por causa do NetworkManager, que está sendo executado ...
[root@localhost ~]# systemctl status NetworkManager.service

Alguma idéia de por que não tenho rede?
