Hi,
        Basic questions about how SSH works.

Say I have a windows 2000 machine which has the SSHD(OpenSSH Server)
running. And I have 3 users U1 U2 and U3 on the server. I created the
key pair for U1 using the ssh-keygen.exe of type DSA.

        Question No. 1 How do i create public-private keys for each of the
users? When I login as U2 to the machine and run the ssh-keygen it
asks me whether i wnat to rewrite the existing id_dsa file. This is
the file as I created for User U1. What should be done to create the
key pairs for all the users on the server.?

Say I have to access this server from 3 different machines.
        Question No. 2 Do I Copy the public key of each of the user in the
Server to these client machines? Where do I copy them. Say for each
session I might be logging in as a different user. My ssh client would
be a perl program trying to communicate with the the server. The user
name would be known only at the run time. So inorder to use the public
key authentication method do I copy the public keys to the client
machine?? If so to which file?? Which directory??

Thanks a lot in advance.
