Я настроил интерфейс eno2 по ошибке в Debian Stretch, теперь я удалил его из /etc/network/interfaces и теперь выглядит так:

# 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

Итак, команда ifconfig показывает эти интерфейсы:

docker0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 172.17.0.1  netmask 255.255.0.0  broadcast 172.17.255.255

Но ip link show показывает интерфейс eno2 также, если он еще не существует:

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

    link/ether **:**:**:**:**:** brd ff:ff:ff:ff:ff:ff

Я пытался удалить ненастроенный интерфейс с помощью ip link delete eno2 , но он возвращает ошибку RTNETLINK answers: Operation not supported

Как я могу удалить интерфейс eno2 из ip link show?

ОБНОВЛЕНИЕ: команда ispconfig -a фактически отображает интерфейс eno2, но этот ник не существует физически в системе, поэтому я хочу удалить его.

Вы получили это задом наперед: аппаратный сетевой интерфейс не определен в /etc/network/interfaces . Они обнаруживаются ядром и затем доступны. Если их нет в /etc/network/interfaces , они останутся неиспользованными и находятся в состоянии «выключено».

ifconfig , по умолчанию, будет отображать только те интерфейсы, которые работают. Если вы хотите увидеть все интерфейсы, используйте ifconfig -a . Затем вы увидите eno2 , который в настоящее время не работает.

Чтобы удалить eno2 , вам нужно физически удалить его из системы.

Ваш выделенный сервер поставляется с двухпортовой сетевой картой. Это очевидно в lspci . Поскольку это двухпортовая сетевая карта, вы не можете удалить второй порт.

Все процессоры Atom семейства Avoton (C2000) имеют как минимум 2 встроенных MAC-адреса Ethernet.
