Linux에서 ip link set tap0 netns XX네임 스페이스 XX를 장치 tap0에 어트 리뷰 션 할 수 있다는 것을 알고 있습니다 . 하지만 그 후에 tap0공개 (이름없는) 네임 스페이스 로 되돌리려면 어떻게해야 합니까?
먼저 인터페이스를 나열합니다.
[root@host ~]# ip link list
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT qlen 1000
link/ether 52:54:00:4e:ca:5c brd ff:ff:ff:ff:ff:ff
3: veth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000
link/ether e6:da:05:95:2f:4e brd ff:ff:ff:ff:ff:ff
4: veth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000
link/ether 4a:73:df:f1:87:26 brd ff:ff:ff:ff:ff:ff
netns testns에 장치 veth1을 넣습니다.
[root@host ~]# ip link set veth1 netns testns
우리는 그것을 확인할 수 있습니다
[root@host ~]# ip link list
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT qlen 1000
link/ether 52:54:00:4e:ca:5c brd ff:ff:ff:ff:ff:ff
4: veth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000
link/ether 4a:73:df:f1:87:26 brd ff:ff:ff:ff:ff:ff
[root@host ~]# ip netns exec testns ip link list
1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN mode DEFAULT
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
3: veth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000
link/ether e6:da:05:95:2f:4e brd ff:ff:ff:ff:ff:ff
그런 다음 다시 기본 netns로 설정합니다.
[root@host ~]# ip netns exec testns ip link set veth1 netns 1
그리고 다시 들어 왔는지 확인합니다.
[root@host ~]# ip netns exec testns ip link list
1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN mode DEFAULT
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
[root@host ~]# ip link list
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT qlen 1000
link/ether 52:54:00:4e:ca:5c brd ff:ff:ff:ff:ff:ff
3: veth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000
link/ether e6:da:05:95:2f:4e brd ff:ff:ff:ff:ff:ff
4: veth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000
link/ether 4a:73:df:f1:87:26 brd ff:ff:ff:ff:ff:ff
귀하의 경우에는 veth1을 tap0으로 바꿔야합니다. 그래서 사실 :
[root@host ~]# ip netns exec testns ip link set tap0 netns 1
