Linux下两台笔记本电脑adhoc模式搭建局域网跟adhoc无线自组织网络.doc

一课资料网/Linux下两台笔记本电脑adhoc模式搭建局域网跟adhoc无线自组织网络1,准备工作两台电脑无线网卡均配置成adhoc模式,选择信道6,ESSID为long. (信道6是我电脑旁边无线路由器所在的信道,不清楚它是否会对无线路由信号产生干扰,当然目前我把无线路由器电源拔了。A主机网卡配置为:IP=4,NETMASK=,GA TEWAY=B主机网卡配置为:IP=1,NETMASK=,GA TEWAY=此时在A主机上ping 1能ping通.当然如果用无线路由器连接的话,跟有线一样的,很简单,实际上无线路由器会把连接它的有线还是无线的都分配到一个子网。2,改变下B主机的网卡设置B主机网卡配置为:IP=1,NETMASK=,GA TEWAY=此时在A主机上ping 1 ping不通2,分别在两台主机上运行aodv无线路由协议,B主机终端显示如下:19:51:20.754 main: In wait on reboot for 15000 milliseconds.
