讨厌的ipv6

之前有人问android的开发主机用什么系统
ubuntu 8.10, 9.04,9.10都有人用，我用的是debian testing.

之前ddms用了一段时间后来用不了了，用不了就算了，就用gdb，前段时间
做android CTS不用它不行了，不得不来解决这个问题。

debian这种技术性的社区就是爱先进。现在也没什么人用ipv6，
它非要放进去，结果java的net功能就问题了。

vax:/etc/sysctl.d# cat bindv6only.conf
# This sysctl sets the default value of the IPV6_V6ONLY socket option.
#
# When disabled, IPv6 sockets will also be able to send and receive IPv4
# traffic with addresses in the form ::ffff:192.0.2.1 and daemons listening
# on IPv6 sockets will also accept IPv4 connections.
#
# When IPV6_V6ONLY is enabled, daemons interested in both IPv4 and IPv6
# connections must open two listening sockets.
# This is the default behaviour of almost all modern operating systems.

net.ipv6.bindv6only = 1
vax:/etc/sysctl.d#


这里设置成0就可以了
net.ipv6.bindv6only = 0
最好还是reboot一下
vax:/proc/sys/net/ipv6# ls
bindv6only  icmp         ip6frag_low_thresh      ip6frag_time    neigh  xfrm6_gc_thresh
conf        ip6frag_high_thresh  ip6frag_secret_interval  mld_max_msf    route
vax:/proc/sys/net/ipv6# echo 0 >bindv6only


最近从事秘密项目，暂时不能写，可能几个月之后能披露出来:)
