网络不通怎么办?
1) 用 lanscan 看系统网卡状态
如果某个网卡硬件状态(HdwState)是DOWN,首先检查网线和网卡指示灯,如果指示灯不亮,说明该网卡有可能存在硬件问题,请立刻拨打惠普热线电话:800-810-7000 或010-65643800
1) 用 ping 命令检查网络通讯是否建立。例如:
# ping -i 15.85.114.14 15.85.114.13
PING 15.85.114.13: 64 byte packets
64 bytes from 15.85.114.13: icmp_seq=3. time=1. ms
64 bytes from 15.85.114.13: icmp_seq=4. time=0. ms
64 bytes from 15.85.114.13: icmp_seq=5. time=0. ms
64 bytes from 15.85.114.13: icmp_seq=6. time=0. ms
64 bytes from 15.85.114.13: icmp_seq=7. time=0. ms
