八 网络故障定位方法
网络不通的诊断过程:
ifconfig 查看网卡是否启动 (up)
netstat –i 查看网卡状态
Ierrs/Ipkts 和 Oerrs/Opkts是否>1%
ping自己网卡地址 (ip 地址)
ping其它机器地址,如不通,在其机器上用diag检测网卡是否有问题。
在同一网中, subnetmask 应一致。
网络配置的基本方法:
(1) 如需修改网络地址、主机名等,一定要用 chdev 命令
# chdev –l inet0 –a hostname=myhost
# chdev -l en0 -a netaddr='9.3.240.58' -a netmask=255.255.255.0’
(2) 查看网卡状态:# lsdev –Cc if
(3) 确认网络地址:# ifconfig en0
(4) 启动网卡:# ifconfig en0 up
(5) 配置路由
有两种方式加入路由:
永久路由
# chdev -l inet0 -a route=’10.47.0.0’,’9.3.240.59’
临时路由
# route add 10.47.1.2 9.3.240.59
用命令 netstat -rn 查看路由表
