ssh issue on windows 7 (gitbash vs. windows cmd)
提问by Asad Iqbal
I am able to use ssh (i.e., for 'git' with heroku or github etc.) through GitBash, but I cannot do the same from Windows cmd prompt on the same machine. What can be the problem? If I recall correctly, it used to work from cmd prompt.
我可以通过 GitBash 使用 ssh（即，对于带有 heroku 或 github 等的“git”），但我无法在同一台机器上从 Windows cmd 提示符执行相同操作。可能是什么问题？如果我没记错的话，它曾经在 cmd 提示符下工作。
The error I'm getting is:
我得到的错误是：
Permission denied (publickey). fatal: The remote end hung up unexpectedly
I got both logs: here is last four lines from cmd which are different from 'git bash':
我得到了两个日志：这里是来自 cmd 的最后四行，与“git bash”不同：
debug1: Trying private key: /.ssh/identity
debug1: Trying private key: /.ssh/id_rsa
debug1: Trying private key: /.ssh/id_dsa
debug1: No more authentication methods to try.
Permission denied (publickey).
in case of Git bash: the respective lines are:
在 Git bash 的情况下：相应的行是：
debug1: Trying private key: /c/Users/user1/.ssh/identity
debug1: Offering public key: /c/Users/user1/.ssh/id_rsa
debug1: Remote: Forced command: gerve user1
debug1: Remote: Port forwarding disabled.
debug1: Remote: X11 forwarding disabled.

As hinted by @snemarch, setting following env var solved my problem:
正如@snemarch 所暗示的，设置以下 env var 解决了我的问题：
set HOME=C:\Users\user1

Since you are using GitHub, from cmd try
由于您使用的是 GitHub，因此从 cmd 尝试
ssh -v -T [email protected]
See the keys that it is presenting. Maybe try from Git Bash also and compare the output.
查看它显示的键。也许也尝试使用 Git Bash 并比较输出。
This could be because %HOME% is not correctly set. Set it to the directory that contains your .sshdirectory ( and hence the keys)
这可能是因为 %HOME% 设置不正确。将其设置为包含您的.ssh目录（以及密钥）的目录

Look at the file paths - "/.ssh/identity", in the case of cmd.exe, is probably not where you've got your SSH keys :). Probably a case of homedir expansion being done when you're on the git-bash, but not on native cmd.exe .
查看文件路径 - 在 cmd.exe 的情况下，“/.ssh/identity”可能不是您获得 SSH 密钥的地方:)。当您使用 git-bash 时，可能会进行 homedir 扩展，而不是本机 cmd.exe 。
Instead of using cygwin ssh and the regular ssh key files, consider using PuTTY's plink for SSH program and pageant for ssh-agent.
不使用 cygwin ssh 和常规的 ssh 密钥文件，考虑使用 PuTTY 的 plink 进行 SSH 程序和选美的 ssh-agent。

I'd double check your system path includes a reference to your git/bin location
我会仔细检查您的系统路径是否包含对您的 git/bin 位置的引用
