SSH is looking in the wrong place for the public/private key pair on Windows

I'm trying to configure GIT on my Windows XP machine, but SSH keeps creating and looking for the public/private key pair in non-sensical places, e.g. /.ssh/id_rsa

Is there a configuration file in the GIT Installation for Windows where I can switch this to my home directory, or another user defined place? By default, it of开发者_运维知识库fers to create new key pairs at //.ssh/id_rsa but that gives me the error "Could not create directory '//.ssh'." And when I'm able to find a directory I can create it in, GIT won't look there.

Figured out how to manually set my home directory in Windows XP:

1. Right click "My Computer"
2. Choose the "Advanced" tab
3. Click the "Environmental Variables" button
4. Under the "System variables" section, click "New"
5. In the "Variable name" enter in "home".
6. In the "Variable value" enter in the path to your profile.

To do the same via command prompt do :

setx HOME "your\path\to\home"

( Please note the suffix x - This is used to persist the change )

Recommended method from MSYS2 is to set db_home in /etc/nsswitch.conf to your home directory.

Credit to @VarunAgw for pointing in the right direction.

Git-for-Windows includes env in db_home, which should read your HOME bash variable, however, it is unreliable.

I was having a similar problem on Windows 7. The HOME environment variable seemed to be set correctly:

$ echo $HOME
C:\Users\craibuc

However, attempts to connect to test github's ssh access failed:

For some reason, ssh was attempting to access C/.ssh.

When I set the variable using setx HOME /c/users/craibuc and restarted the shell, I was able to connect:

$ ssh -T git@github.com
Warning: Permanently added the RSA host key for IP address '192.30.252.130' to the list of known hosts.
Hi craibuc! You've successfully authenticated, but GitHub does not provide shell access.

Check which ssh to see if you are using /usr/bin/ssh or something else, that might have installed by accident.

In my case my ssh was replaced by Chocolatey after installing rsync. After running choco uninstall rsync, my SSH was working again.

I had the same kind of problem when using a machine with domain policy setting the user profile to a network drive (in this case mapped to Z:).

When trying to do anything from Powershell I'd get messages like this. Setting home PATH variable didn't help.

git clone ssh://myusername@mydomain.com:1234/myproject
Cloning into 'myproject'...
Could not create directory '/z/.ssh'.

Are you sure you want to continue connecting (yes/no)? yes

Please make sure you have the correct access rights
and the repository exists.

When I cloned from git bash it was fine, as /z/.ssh etc is a valid way to point to Z:\.ssh from a shell.

ln -s /c/Users/rofrol/.ssh /home/rofrol/ worked for me.

This did not:

$ echo $HOME
/c/Users/rofrol

$ cat ~/nsswitch.conf
db_home: /c/Users/rofrol

$ cat /home/rofrol/nsswitch.conf
db_home: /c/Users/rofrol

$ cat /etc/nsswitch.conf
# Begin /etc/nsswitch.conf

passwd: files db
group: files db

db_enum: cache builtin

#db_home: cygwin desc
db_home: /c/Users/rofrol
db_shell: cygwin desc
db_gecos: cygwin desc

# End /etc/nsswitch.conf

Probably because of this:

SSH will require /home/$USER

On Windows 7 Just Place your Private Key ( id_rsa ) inside C:\Users\.ssh FOLDER If .ssh Folder doesnt exist just create it. Download GIT for Windows, cd into your Project Directory and do git clone ssh://@/.git
