手机/平板到NAS的速率测试

问题及解决

根据如下拓扑,用iphone和ipad查看nas的高清资源总是卡,低于5mbps码率的资源没问题,当网线连接时,50mbps码率的视频也没问题,所以严重怀疑wifi出了问题,但又不好查哪里的问题,我在AppStore上找了一圈,也没有一个像样的wifi 分析软件,即使收费也能接受呀。。。

Iphone/Ipad — <wifi 5g> — wrt1200ac —<GE>—918+

问题现在已经解决了,由于我的wrt1200ac刷的是OpenWRT,开源的wifi驱动不稳定,导致时不时的卡。我在918+上部署了docker版本的speedtest,从iphone/ipad上测试了下tcp性能,发现测不出问题,速率都挺正常(只给最终结果,无法显示平均还是最大),如下:

被恶意注入钓鱼网站链接

当游览blog时,发现网站左上角有奇怪的link,点进去后竟是黄网。。。想了想这几天没点什么不正常的网站呀,前几天还是好好的,啥情况。。。😓

我需要找到这个link在哪里,经过TS排查,发现link只会出现在我现有这个主题下,换主题就没问题了,所以我去blog管理台找,发现找不到。。。后来登录我的vps,用下面方式找到,注:网站名称已被我隐去:

[root@frank wordpress_data]# find . | xargs grep -ri "xxxx"
./wp-content/themes/page-shippou/header.php:<div id="1049"><a href="https://xxxx.com">xxx voglio</a></div>
./wp-content/themes/page-shippou/header.php:<div id="1049"><a href="https://xxxx.com">xxx voglio</a></div>
./wp-content/themes/page-shippou/header.php:<div id="1049"><a href="https://xxxx.com">xxx voglio</a></div>
./wp-content/themes/page-shippou/header.php:<div id="1049"><a href="https://xxxx.com">xxx voglio</a></div>
./wp-content/themes/page-shippou/header.php:<div id="1049"><a href="https://xxxx.com">xxx voglio</a></div>
grep: ./wp-content/plugins/backupwordpress/vendor/symfony/finder/Tests/Fixtures/with: No such file or directory
grep: space: No such file or directory
grep: ./wp-content/plugins/backupwordpress/vendor/symfony/finder/Tests/Fixtures/with: No such file or directory
grep: space/foo.txt: No such file or directory

现在才发现wordpress控制台下search不太好使呀。。。按照路径找到文件,找到下面内容删掉后恢复,然后赶紧改admin密码😅,先观察几天再说:
