使用SSH使用dulwich进行克隆-获取dulwich以了解公钥(挂起异常)

Question

我设法使用带有HTTP url的dulwich进行克隆，但是当我尝试使用SSH进行克隆时，我得到了一个"HangupException“。有没有可能dulwich无法访问~/.ssh文件夹中的公钥，因此无法进行SSH连接？是否需要在dulwich配置中添加此功能？下面是我得到的错误：

    error: Application connect timed-out.
fatal: Host key verification failed.

Answer 1

从堆栈中，我可以看到它仍然尝试使用http客户端。您应该检查您向porcelain.clone提供了什么source。你可以尝试在client.get_transport_and_path函数中使用哪种客户端。

Answer 2

我最终通过使用这里提到的方法解决了这个问题：http://poquitopicante.blogspot.co.uk/2012/09/dulwich-porcelain.html

dulwich.client中的ssh供应商应该由具有ssh密钥对的地址的供应商继承，以启用连接。
