from man ssh
-----
The file $HOME/.ssh/authorized_keys lists the public keys that are per-
mitted for logging in.ssh implements the RSA authentication protocol automatically. The user
creates his/her RSA key pair by running ssh-keygen(1). This stores the
private key in $HOME/.ssh/identity and stores the public key in
$HOME/.ssh/identity.pub in the user's home directory. The user should
then copy the identity.pub to $HOME/.ssh/authorized_keys in his/her home
directory on the remote machine (the authorized_keys file corresponds to
the conventional $HOME/.rhosts file, and has one key per line, though the
lines can be very long). After this, the user can log in without giving
the password. -----
My personal opinion is that the last line causes a bit of confusion for some users,
as giving a non-null passphrase when the specified key is generated causes the user
to have to enter the passphrase (which can be interpreted as a request for
the password).

Hello,
I am attempting to replace an automated ftp process with sftp. This ftp process , which runs on a Windows 2000 server, grabs EDI files from our HPUX 11.0 server every 10 minutes and places then on the EDI Server. I would like to modify this process to use sftp and use the SSH keys for password less connections ..i.e. public key authentication.
So far I have installed and tested SSH on the HPUX 11.0 server. I have also installed cygwin on the Windows 2000 server and preformed a successful test using sftp. The next step is to setup the public key authentication so that I can use sftp in the automated ftp process.
I have Google'd the net and searched the archives of this list but have not been able to find any good documentation that shows me exactly what needs to be done in order to get the authentication working in my environment (mix of Windows and UNIX). So far I have been able to generate the private and public keys for both servers as show below:
HPUX 11.0 - ssh-keygen -t dsa -f hp_sftp_user This command create the following files hp_sftp_user & hp_sftp_user.pub
Windows / CYGWIN - ssh -keygen -t dsa -P "" This was an interactive session and I was asked for the file names. win2k_sftp and win2k_sftp.pub were generated.
** Please let me know if there are better ways to generate the above keys ..including any additional options I may need.
If the above mentioned keys are workable ... I now need a solution that will allow me to put these files to use on both the HPUX and Windows servers so I will be able to use password less connections .. which is especially need for the scheduled ftp process running on Windows.
Thanks in advance for you help, Chris Shehan
