~ # ping 192.168.0.199 PING 192.168.0.199 (192.168.0.199): 56 data bytes ping: sendto: Network is unreachable
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
