之前刷的一个openwrt的路由，虽然能很方便的登陆google和百度，但是发现不少网站还是登陆不上去，连我自己的博客也无法登陆。
检查连一下，发现是我的博客的域名无法解析。

那就是一个域名解析的问题了，由于我是通过dnsmasq进行域名解析，在我的/etc/dnsmasq.d目录下，已经有连需要特别解析的配置，那么剩下的就是一般的域名走默认配置。
检查了一下，发现没有配置no-resolv和server。把/etc/dnsmasq.conf添加如下，就可以解决了（见第6行～12行）：
# for targets which are names from DHCP or /etc/hosts. Give host # "bert" another name, bertrand # The fields are <cname>,<target> #cname=bertand,bert conf-dir=/etc/dnsmasq.d #Add by Jimmy BEGIN HERE no-poll no-resolv all-servers cache-size=5000 server=114.114.114.114 #Add by Jimmy END HERE
