多VNIC为非主要VNIC分配IPv4

下载 https://docs.oracle.com/en-us/iaas/Content/Resources/Assets/secondary_vnic_all_configure.sh
执行bash secondary_vnic_all_configure.sh -c为所有在控制台已附加的VNIC在机器内分配到IPv4（内网）

重启网络问题

请在选择系统开机后重装系统以避免, 本人已两次因为原系统在重启与磁盘调整上跌跟头, 第二次使用一个sh解决但没有治根

无法连接至服务器

没有设置好防火墙或未在Ubuntu22.04上使用ECDSA密钥对, 以及IP被GFW封禁的可能

不能root登录

编辑/root/.ssh/authorized_keys, 删除 no-port-forwarding,no-agent-forwarding,no-X11-forwarding,command="echo 'Please login as the user \"ubuntu\" rather than the user \"root\".';echo;sleep 10;exit 142" 即可
