Well that didn't work!

Testing this with an ssh $(hostname) id so I don't think I need to mkdir. Did this command anyway...

$ ssh remotehost.com tee -a .ssh/authorizedkeys < ~/.ssh/id_rsa.pub
2>>/dev/null

OK...

$ chmod go-rwX ~/. ~/.ssh

OK...

$ ssh remotehost.com chmod go-rwX . .ssh

OK...

Now for the test:

ssh $(hostname) id
adefaria@adefaria's password:

Darn! Still need to enter my password!

Any other ideas?

Hi,

CYGWIN does not allow a password to be passed. I have tried to use a

Is it possible to do this with CYGWIN?

Umm, why not use "ssh"?

When I use ssh I get prompted for a password.
