yum install libpcap
yum install libpcap-devel
2 测试 vi test.c
#include <pcap.h>
#include <stdio.h>
int main()
{
char errBuf[PCAP_ERRBUF_SIZE], * device;
device = pcap_lookupdev(errBuf);
if(device)
{
printf("success: device: %s\n", device);
}
else
{
printf("error: %s\n", errBuf);
}
return 0;
}
3 编译
gcc test.c -o test -lpcap
4 运行
