标题: 网络抓包APP开发，报错:eth0: You don't have permission to perform this capture on that device (socket: Operation not permitted)
[md]### 【问题描述】

1. 使用libpcap.so，编写native代码调用
2. ```
pcap_t *handle = pcap_open_live(device->name, BUFSIZ, 1, 1000, errbuf);
         if (handle == NULL) {
            OH_LOG_ERROR(LOG_APP, "Open - pcap_open_live failure %{public}s", errbuf);
            return -1;
         }

```
3. Open - pcap_open_live failure eth0: You don't have permission to perform this capture on that device (socket: Operation not permitted)
4. 把网络相关的权限都配置了

```

看看 selinux 和应用权限（是不是系统应用）
