最近發生一件怪事, VM suspend 當掉之後, networkmanager 顯示 inactive
用 nmcli 看系統, 所有的 interface 都是 unmanaged
$ nmcli
ens33: unmanaged
"Intel 82545EM Gigabit Ethernet Controller (Copper) (PRO/1000 MT Single Port Adapter)"
ethernet (e1000), 00:0C:29:29:D4:AC, hw, mtu 1500
ens38: unmanaged
"Intel 82545EM Gigabit Ethernet Controller (Copper) (PRO/1000 MT Single Port Adapter)"
ethernet (e1000), 00:0C:29:29:D4:B6, hw, mtu 1500
ens39: unmanaged
"Intel 82545EM Gigabit Ethernet Controller (Copper) (PRO/1000 MT Single Port Adapter)"
ethernet (e1000), 00:0C:29:29:D4:C0, hw, mtu 1500
ens40: unmanaged
"Intel 82545EM Gigabit Ethernet Controller (Copper) (PRO/1000 MT Single Port Adapter)"
ethernet (e1000), 00:0C:29:29:D4:CA, hw, mtu 1500
lo: unmanaged
loopback (unknown), 00:00:00:00:00:00, sw, mtu 65536 |
nmcli 看 general, 狀況是 asleep, 找了許多網路上的方法都沒有用
# nmcli g STATE CONNECTIVITY WIFI-HW WIFI WWAN-HW WWAN asleep none enabled enabled enabled enabled |
最後自己亂試指令, 果然回來了
$ nmcli networking on |
