Question

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.

The error I’m getting is:

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’:

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:

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.

Resolved

As hinted by @snemarch, setting following env var solved my problem:

set HOME=C:\Users\user1

Since you are using GitHub, from cmd try

ssh -v -T [e-mail]

See the keys that it is presenting. Maybe try from Git Bash also and compare the output.

This could be because %HOME% is not correctly set. Set it to the directory that contains your .ssh directory ( and hence the keys)
