ssh (open)

[jbk]

I have enabled openssh and have created my dsa private and public keys 
in $home/.ssh/ on my rh7.2server. I have also copied the public key to 
authorized_keys2 in the same directory. I can login to my server now 
from my msbox via cygwin using ssh. The following is an edited excerpt 
of the login sequence.

bash<johndat>$ ssh -l johndoe bagend

What I would like to know is, is it possible to set up the login process 
so I don't have to enter my password each time? My username is different 
between machines.
