OpenSSH Keys and Putty

[Jon]

Thanks to everyone who replied.  I gave up on trying to use one key.  I
made a seperate key pair for putty and comercial SSH.  

Putty allows you to copy the key in OpenSSH format right from the puttygen
program.  For comercial SSH I had to do the following:

$ ssh-keygen -i -f rsa_putty.pub >> .ssh/authorized_keys 

Passwords are turned off and my firewall is happy now... thanks again.
