给 Debian 增加了 ipv6 之后，service networking restart 失败，网卡丢失。
nano /etc/network/interfaces iface ens18 inet6 static address 2a10:cc40:233:136::1 netmask 64 gateway 2a10:cc40:233::1 # gateway fe80::1
重启网卡后网卡丢失
root@vps-2299:/etc/network# service networking restart Job for networking.service failed because the control brocess exited with error code. See "systemctl status networking.service" and "journalctl -xer for details root@vps- 2299:/etc/network#
根据提示 执行 systemctl status networking.service
root@vps-2299:/etc/network# systemctl status networking.service
networking. service - Raise network interfaces
Loaded: loaded (/lib/systemd/system/networking.service; enabled; vendor pr>

Main PID: 303864 (code=exited, status=1/FAILURE)

lines 1-7/7 (END)
然后 查看 nano /lib/systemd/system/networking.service ，发现这纯属浪费时间
将 TimeoutStartSec=5min 改为 TimeoutStartSec=5s
systemctl daemon-reload systemctl enable networking.service
最后 ifup -a ，才发现是 /etc/iptables.up.rules 丢失，导致网络无法重启
root@vps-2299:/etc/network# ifup -a /etc/network/if-pre-up.d/iptables: line 2: /etc/iptables.up.rules: No such file or directory run-parts: /etc/network/if-pre-up.d/iptables exited with retuan code 1 ifup: pre-up script failed root@vps-2299:/etc/network#
touch /etc/iptables.up.rules
之后，重启网卡成功
