Eu configurei uma interface eno2 por engano no Debian Stretch, agora eu deletei de /etc/network/interfaces e agora é assim:
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
allow-hotplug eno1
iface eno1 inet dhcp
# IPv6 interface
iface eno1 inet6 static
address ****:****:****::1
netmask 48
Então, o comando ifconfig mostra essas interfaces:
docker0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
inet 172.17.0.1 netmask 255.255.0.0 broadcast 172.17.255.255

Mas o ip link show também mostra a interface eno2 se ainda não existir:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
link/ether **:**:**:**:**:** brd ff:ff:ff:ff:ff:ff
3: eno2: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
link/ether **:**:**:**:**:** brd ff:ff:ff:ff:ff:ff
4: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN mode DEFAULT group default
link/ether **:**:**:**:**:** brd ff:ff:ff:ff:ff:ff
Eu tentei excluir a interface não configurada com o ip link delete eno2 , mas ele retorna o erro RTNETLINK answers: Operation not supported
Como posso remover a interface eno2 de ip link show ?
ATUALIZAÇÃO: o comando ispconfig -a na verdade mostra a interface eno2, mas esse nic não existe fisicamente no sistema e é por isso que eu quero deletá-lo.
