无法使用IPv6通过SSH推/拉到bitbucket

Question

当我可以推/拉到bitbucket:

• 从我的工作电脑通过ssh键 id_rsa_bitbucket_work
• 从我的笔记本电脑,但只有通过ssh键登录VPN(Cisco AnyConnect)id_rsa_bitbucket.我的VPN有一个静态IP.
• 始终使用https.

当我不能推/拉到bitbucket时:

• 从我的笔记本电脑随时通过ssh键连接VPN ida_rsa_bitbucket.
• 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.

我的适当条目~/.ssh/config是:

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,通过SSH连接到github存储库始终有效.

我检查过以确保:

• 我的SSH代理正在运行并且加载了正确的密钥.
• 无论VPN设置如何,我的SSH代理都会分发相同的密钥.

ssh -Tv bitbucket未登录VPN时的输出为:

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网站上发现此问题后,我尝试添加104.192.143.2 bitbucket.org到我的/etc/hosts文件中.这并没有解决问题.

Answer 1

在Bitbucket支持的大量帮助下更新:

经过更多的研究,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.如果我直接插入我的调制解调器并运行ssh -Tvv bitbucket它通过IPv6正确验证.

为了解决这个问题(当我购买新的路由器时),我强迫连接到bitbucket只使用IPv4加入AddressFamily inet我的~/.ssh/config file(感谢:https://stackoverflow.com/a/35113901/7735643).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
