开发板：荔枝派Zero
环境：linux主线5.11
问题：能ping通www.baidu.com，电脑也能ping通板子，板子却ping不通电脑，localhost、127.0.0.1都ping不通。
附：解决这个主要是用ffmpeg和ffserver推流出现http://127.0.0.1:8090/feed1.ffm: Connection timed out的问题，现在在电脑浏览器能打开ffserver的stat网页，但推出来的视频流一直是0kb，播放器也一直在转圈圈加载，所以感觉是这方面的问题。万分感谢。

试一试这个
谢谢谢谢，可以了，ffmpeg也可以推流了。
抱歉哈，没系统学过linux，刚查了下才知道lo是环回，有点傻了。再次感谢。
