Turris Omnia（结解析器）：t.co 无法解析。twitter.com 确实如此

  • 772

我的 Turris Omnia 无法解析 t.co，但与其他域（例如 twitter.com 或 x.co）没有问题。本地名称 (hpdisk.lan) 也可以使用：

root@turris:~# ping t.co
ping: t.co: Name does not resolve

root@turris:~# ping twitter.com
PING twitter.com (104.244.42.193) 56(84) bytes of data.
64 bytes from 104.244.42.193 (104.244.42.193): icmp_seq=1 ttl=58 time=11.5 ms

tange@turris:~$ ping x.co
PING x.co (148.72.51.157) 56(84) bytes of data.
64 bytes from 157.51.72.148.host.secureserver.net (148.72.51.157): icmp_seq=1 ttl=42 time=139 ms

tange@turris:~$ ping hpdisk.lan
PING hpdisk.lan (192.168.1.30) 56(84) bytes of data.
64 bytes from 192.168.1.30 (192.168.1.30): icmp_seq=1 ttl=64 time=0.374 ms

路由器查询身份验证名称服务器没有问题，因此不是由某些网络过滤或路由问题引起的：

root@turris:/tmp/log# dig @a.r06.twtrdns.net. t.co

; <<>> DiG 9.18.24 <<>> @a.r06.twtrdns.net. t.co

查找 u.co 会导致此流量（与 [as,uz].co 非常相似）：

查找 t.co 不会导致任何流量。闻起来好像 Knot Resolver 认为它是 t.co 的授权

我已尝试重新启动路由器。这并没有解决问题。

    修复者：

    root@turris:~# /etc/init.d/adblock disable
root@turris:~# reboot

    t.co 似乎位于广告拦截列表中，并且 Turris Omnia 上默认启用广告拦截。
