ifconfig 및 ip link show는 다른 인터페이스를 표시합니다.

나는 eno2 데비안 스트레치에서 실수로 인터페이스를 삭제했습니다. /etc/network/interfaces 이제는 이렇게됩니다. 

# 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

그래서 ifconfig 명령은 다음 인터페이스를 표시합니다. 

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

하지만 ip link show 보여 주다 eno2 인터페이스가 더 이상 존재하지 않는 경우 : 

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

비 구성 인터페이스를 삭제하려고했습니다. ip link delete eno2, 오류를 반환합니다. RTNETLINK answers: Operation not supported

어떻게 제거 할 수 있습니까? eno2 인터페이스는 ip link show?

최신 정보: 그만큼 ispconfig -a 명령은 실제로 eno2 인터페이스를 보여 주지만이 NIC는 물리적으로 존재하지 않으므로 삭제하려는 이유가 있습니다.

뒤로 : 하드웨어 네트워크 인터페이스가 아닙니다. 한정된 ...에서 /etc/network/interfaces. 커널에 의해 감지되어 사용 가능합니다. 당신이 그들 안에 있지 않으면 /etc/network/interfaces사용하지 않고 "다운"상태로 유지됩니다.

ifconfig 기본적으로 "up"인 인터페이스 만 표시합니다. 모든 인터페이스를 보려면, 다음을 사용하십시오. ifconfig -a. 그러면 너는 볼 것이다. eno2, 현재 다운됩니다.

제거 eno2, 시스템에서 실제로 제거해야합니다.

전용 서버에는 이중 포트 NIC가 함께 제공됩니다. 이것은 lspci. 듀얼 포트 NIC이기 때문에 두 번째 포트를 제거 할 수 없습니다.

"Avoton"(C2000) 제품군의 모든 Atom 프로세서에는 최소 2 개의 내장 이더넷 MAC가 있습니다.

하지만 내 시스템에는 실제로 인터페이스가 없습니다. 온라인 네트워크의 전용 서버이며 NIC가 1 개뿐입니다. eno2 인터페이스 구성이 실수로 추가되었으므로 물리적으로 존재해서는 안됩니다.

출력을 확인하십시오. dmesg 네트워크 장치에 대한 정보를 확인하십시오. 검사 이 대답 어떤 드라이버가 "고장 났는지"를 결정하는 방법에 대해 설명합니다. 또한 인터페이스를 무시하지 않는 이유는 무엇입니까? 가장 큰 피해는 없습니다. // 또한, 다시 명확히하기 위해 : 특별한 옵션을 사용하지 않는 한 interfaces, 네트워크 인터페이스 ~하지 않을 것이다 만들 수 있습니다. 실수로 이러한 옵션을 사용하지 않을 것입니다.
