用Linode爬梯子上Google近段时间整天会被提示说 We're sorry…… but your computer or network may be sending automated queries. To protect our users, we can't process your request right now.See Google Help for more information. 百度查了下(这种情况只能百度了!!!!!)原来是Google把linode的ipv6给屏蔽了,到你的VPS中把ipv6禁用就可以了 我用的是CentOS 7 root权限下 echo '1' > /proc/sys/net/ipv6/conf/lo/disable_ipv6echo '1' > /proc/sys/net/ipv6/conf/all/disable_ipv6echo '1' > /proc/sys/net/ipv6/conf/default/disable_ipv6 再用SSH试访问一下,发现再也没有讨厌的提示了! 参考:http://codelife.me/blog/2013/11/16/google-block-linode-traffic-over-ipv6/
