无法使用IPv6通过SSH推/拉到bitbucket

标签： git ssh bitbucket vpn ipv6

当我可以推/拉到bitbucket时：

  • 从我的工作电脑通过ssh键id_rsa_bitbucket_work
  • 从我的笔记本电脑上，但仅在通过ssh密钥id_rsa_bitbucket登录VPN（Cisco AnyConnect）时。我的VPN有一个静态IP。
  • 始终使用https。

当我无法推/拉到bitbucket时：

  • 通过ssh密钥ida_rsa_bitbucket
    • 随时从我的笔记本电脑连接VPN
  • 当我的工作网络网络上的笔记本电脑不在VPN上时，即使我名义上在同一个网络上，我也会使用VPN。

~/.ssh/config中的相应条目为： 

Host bitbucket
     HostName bitbucket.org
     User git
     IdentityFile ~/.ssh/id_rsa_bitbucket

无论我正在经历什么样的网络/ VPN，都可以通过SSH连接到github存储库。

我已经检查过以确保：

  • 我的SSH代理正在运行并且已加载正确的密钥。
  • 无论VPN设置如何，我的SSH代理都会分发相同的密钥。

未登录VPN时ssh -Tv bitbucket的输出为：

You can use git or hg to connect to Bitbucket. Shell access is disabled.

它似乎连接和验证（通过IPv4？），一切都很好。

更新 在bitbucket网站上找到this issue后，我尝试将104.192.143.2 bitbucket.org添加到我的/etc/hosts文件中。这并没有解决问题。

答案 0 :(得分：7)

在Bitbucket支持的大量帮助后更新：

经过更多研究后，问题似乎出现在我的路由器端（Linksys E3200），并且与IPv6有某种关系。我可以轻松访问仅支持IPv6的站点，并且github的一切正常（这是因为github只是IPv4）。但是，有些东西被过滤掉了，SSH需要正常工作。如果我直接插入调制解调器并运行ssh -Tvv bitbucket，它将通过IPv6正确验证。

为了解决这个问题（当我购买新的路由器时），我强制连接到bitbucket只使用AddressFamily inet添加~/.ssh/config file（感谢：{{ 3}}）。所以bitbucket的更新条目现在为：

Host bitbucket
     HostName bitbucket.org
     User git
     IdentityFile ~/.ssh/id_rsa_bitbucket
     AddressFamily inet
