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 附：常用命令列表： Any
