我有点迷失方向，无法解决这个问题。
这是一台在 Google Compute Engine 上即将推出的机器。
当我尝试访问网络时，它显示“网络无法访问”。
网络似乎正常运行，因为 eth0 具有从 Google DHCP 服务器获取的网络地址。以下是“ifconfig”和“route”的输出
Google 表示这台机器所在的网络是 10.240.0.0/16，网关是 10.240.0.1
route -n 的输出

ifconfig -a 的输出

答案1
以下有效：
sleep 10 (not sure if this line matters but it seems the system needs a few seconds for something to complete?)
sudo udhcpc
sudo route add -net 10.240.0.0 netmask 255.255.0.0 dev eth0
sudo route add default gw 10.240.0.1 eth0
