Yes, double checked.

> 2. Try unsetting "HOME" before running ssh.
C:\>set HOME=
C:\>ssh -v fleet
OpenSSH_5.8p1, OpenSSL 0.9.8r 8 Feb 2011
debug1: Connecting to fleet [192.168.1.30] port 22.
debug1: Connection established.
debug1: permanently_set_uid: 0/0
debug1: identity file /.ssh/id_rsa type -1
...
ssh goes on to create /.ssh off of c:\cygwin and fails since no id_rsa 
files.

Copying .ssh/ into c:\cygwin results in this working.

Try:

c:\>set HOME=/home/tda
c:\>ssh -v fleet
OpenSSH_5.8p1, OpenSSL 0.9.8r 8 Feb 2011
debug1: Connecting to fleet [192.168.1.30] port 22.
debug1: Connection established.
debug1: permanently_set_uid: 0/0
debug1: identity file /home/tda/.ssh/id_rsa type 1
...
(succeeds, but I need HOME to be "correct" for other apps)

Try returning to Windows default:

c:\>set HOME=c:\Users\tda.DCA
c:\>ssh -v fleet
OpenSSH_5.8p1, OpenSSL 0.9.8r 8 Feb 2011
debug1: Connecting to fleet [192.168.1.30] port 22.
debug1: Connection established.
debug1: permanently_set_uid: 0/0
Could not create directory 'c/.ssh'.
debug1: identity file c/.ssh/id_rsa type -1


It looks as if ssh isn't going straight to /etc/passwd for home (unless 
another cygwin app is running in another command prompt), and then HOME 
is getting parsed in some strange way.

No change in behaviour.

Not sure what you mean here.

Thanks for your help.
