Disable IPv6 on Ssh Client

发表于 2017-12-10 分类于随笔

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.
