MSysGit and ssh config. missing

问题:

1) Run Git Bash (C:\Program Files (x86)\Git\bin\sh.exe --login)

$ ssh -v [e-mail]
OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007
debug1: Reading configuration data /c/Users/Alexander Fedorov/.ssh/config
debug1: Applying options for github.com
debug1: Connecting to github.com [207.97.227.239] port 22.
debug1: Connection established.
...
Hi xpoft! You've successfully authenticated, but GitHub does not provide shell access.
...

Okay! ssh config reading well.

2) Run from cmd.exe

C:\Users\Alexander Fedorov>ssh.exe -v [e-mail]
OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007
debug1: Connecting to github.com [207.97.227.239] port 22.
...
debug1: No more authentication methods to try.
Permission denied (publickey).

Nooo. ssh config file is missing...

How... how read config from ssh.exe?

回答1:

What is probably missing is the user environment variable HOME.

If you launch your DOS session from the git-cmd.bat script packaged with msysgit, it should be defined, and you should see %HOME%\.ssh\id_rsa(.pub)

But from any other DOS windows, HOME isn't defined by default (HOMEPATH or USERPROFILE are).
See also "Fix msysGit Portable $HOME location" as an illustration (but you shouldn't need that workaround with recent versions of msysgit and its git-cmd.bat script)
