ubuntu无法访问ipv6了

[hbxtght]

miredo已经安装，/etc/default/ufw中ipv6=yes
ipv6.google.com可以打开
就是访问不了其他的ipv6站
比如晨光BT，我校的PT
ping googleipv6如下

ght@ght-Inspiron-N5010:~$ ping6 ipv6.google.com
PING ipv6.google.com(2404:6800:8005::63) 56 data bytes

ping我们学校的PT如下
ght@ght-Inspiron-N5010:~$ ping6 pt.nwsuaf6.edu.cn
PING pt.nwsuaf6.edu.cn(2001:250:1002::7) 56 data bytes

修改hosts

修改hosts

具体一点，改什么东西？谢谢！

[月下叹逍遥]

修改/etc/hosts文件，将学校的IP和网址添加进去。

[hbxtght]

127.0.0.1 ght-Inspiron-N5010 localhost.localdomain localhost
::1 ght-Inspiron-N5010 localhost6.localdomain6 localhost6
127.0.1.1 ght-Inspiron-N5010

# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
这是我的hosts文件，好像没有v6格式的地址，格式是什么阿？

[月下叹逍遥]

fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

这些都是IP6的IP

问题已经解决，网络连接中auto eth0链接上之后就可以了
