Disable IPv6 on ssh client

问题起于我要经ssh 连git.dn42.us, 比较特别的是我的机器(vps)上启用了IPv6
OpenSSH_7.2p2 Ubuntu-4ubuntu2.2, OpenSSL 1.0.2g  1 Mar 2016
debug1: Reading configuration data /home/seven/.ssh/config
debug1: /home/seven/.ssh/config line 1: Applying options for *
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 19: Applying options for *
debug1: Connecting to git.dn42.us [2607:5300:60:3d95::1] port 22.
以上是ssh的输出。 可以看到是通过IPv6连接的,死活不通。
于是禁用IPv6
~/.ssh/config
Host *
    AddressFamily inet
It works fine.
