操作系统Linux，ping网关的IP地址，检查网络是否联通

可以通过在终端中运行以下命令来ping网关的IP地址，检查网络是否联通：

ping <网关IP地址>

例如，如果网关的IP地址是192.168.1.1，可以运行以下命令：

ping 192.168.1.1

如果网络畅通，你应该能够看到类似以下输出：

PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=1.23 ms
64 bytes from 192.168.1.1: icmp_seq=2 ttl=64 time=1.45 ms
64 bytes from 192.168.1.1: icmp_seq=3 ttl=64 time=1.47 ms

如果网络不通，你会看到类似以下输出：
