Usage: oifcfg iflist [-p [-n]] oifcfg setif {-node <nodename> | -global} {<if_name>/<subnet>:<if_type>}... subnet计算命令： 这是按照子网掩码252计算的网络配置，一会打算使用这个值模拟错误： [root@lunar ~]# ipcalc -bnm 10.10.10.100 255.255.252.0 NETMASK=255.255.252.0 BROADCAST=10.10.11.255 NETWORK=10.10.8.0 IP地址 192.168.0.1 子网掩码 255.255.255.0 AND运算(AND运算法则：1 与1 = 1 ,1 与0 = 0 ,0 与1 = 0 ,0 与0 = 0 ,即当对应位均为1时结果为1，其余为0。) 转化为二进制进行运算： I P 地址 11000000.10101000.00000000.00000001 子网掩码 11111111.11111111.11111111.00000000 AND运算 11000000.10101000.00000000.00000000 转化为十进制后为： 192.168.0.0 <==========该地址为oifcfg需要的地址。
