一、结构体 struct sockaddr_in, struct sockaddr, struct in_addr struct sockaddr_in, struct sockaddr,struct in_addr,这是网络编程中常用的结构体,每次都记不住它们各自的成员是啥,需要临时查,为方便以后的查看,在这里总结下。 struct sockaddr { unsigned short sa_family; /* 地址族, AF_xxx */ char s...

简单的办法是在/etc/rc.d/rc.sysinit文件中加入那些命令: ifconfig eth0 down ifconfig eth0 hw ether xx:xx:xx:xx:xx:xx ifconfig eth0 up 因为这个脚本运行在network之前,所以,MAC跟IP就是对应的 方法4: Linux下的MAC地址更改 首先用命令关闭网卡设备。 /sbin/ifconfig eth0 down 然后就可以修改MAC地...
