用route命令测试,全是空的

~ # route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface

 

原来是文件系统问题

手动命令

~ # ifconfig eth0 up
nuc970-emac0 nuc970-emac0: eth0 is OPENED

~ # ifconfig eth0 192.168.0.4 netmask 255.255.255.0

~ # route add default gw 192.168.0.1
