㈣ 如何用C语言获取网卡的mac地址

为什么一定要用C语言呢？这个用C语言比较麻烦，需要的知识比较多，完全可以用更简单的办法啊。命令行上这样的命令“ipconfig -all | find "物理地址"”，可以很简单的就得到了。
如果是英文系统， 将“物理地址”换成“Physical Address”即可。
如果非的要用C语言，则可以先调用system函数， system("ipconfig -all | find \"物理地址\" > temp.txt" ); 将mac地址信息存入临时文件temp.txt；然后再从中提取。

㈤ linux c 怎么获得服务器mac 地址

获取服务器mac 复制代码 代码如下: <?php /** 获取网卡的MAC地址原码；目前支持WIN/LINUX系统 获取机器网卡的物理（MAC）地址 **/ class GetmacAddr{ var $result = array(); // 返回带有MAC地址的字串数组 var $macAddr; /*构造*/ function __construct($osType){ switch ( strtolower($osType) ){ case "unix": break; case "solaris": break; case "aix": break; case "linux": { $this->for_linux_os(); }break; default: { $this->for_windows_os(); }break; } $temp_array = array(); foreach($this->result as $value){ if(preg_match("/[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f]/i",$value, $temp_array ) ){ $this->macAddr = $temp_array[0]; break; } } unset($temp_array); return $this->macAddr; } /*linux系统中获取方法*/ function for_linux_os(){ @exec("ifconfig -a", $this->result); return $this->result; } /*win系统中的获取方法*/ function for_windows_os(){ @exec("ipconfig /all", $this->result); if ( $this->result ) { return $this->result; } else { $ipconfig = $_SERVER["WINDIR"]."\system32\ipconfig.exe"; if(is_file($ipconfig)) { @exec($ipconfig." /all", $this->result); } else { @exec($_SERVER["WINDIR"]."\system\ipconfig.exe /all", $this->result); return $this->result; } } } } ?> 获取客户端mac地址： 复制代码 代码如下: @exec("arp -a",$array); //执行arp -a命令，结果放到数组$array中 foreach($array as $value){ //匹配结果放到数组$mac_array if(strpos($value,$_SERVER["REMOTE_ADDR"]) && preg_match("/(:?[0-9A-F]{2}[:-]){5}[0-9A-F]{2}/i",$value,$mac_array)){ $mac = $mac_array[0]; break; } } echo $mac; 注：客户端获取的mac不能在本机测试，只能用别的电脑访问才能输出

㈥ c语言，获取本机mac地址，那位大神解答下。

有个简单的方法，提供给你个思路
system("ipconfig /all > tmp.txt");
然后打开tmp.txt
查找本地连接 再找之后的Physical Address字符串，然后找冒号，
取这个冒号后面的值就是mac了
