SSH with RAS key enforcement

[Richard Horton]

I have setup a redhat 7.1 with only ssh v1.99 and I have a windows client using PUTTY and I can connect.

However, I need assistance in generating keys and issuing them to the clients. I want a passphrase and key and a password required for connections.

I dont know how to generate the key that the client needs in order to have the RSA authentication force a key check. I only want valid keys to be allowed access. I would also like a passphrase and a user password requirement as well.

Can someone tell me the valid sshd_config setting I need and how to generate the clients keys and where I need to put them on the linux server. I know where to put them in PUTTY for the client/windows machine. I just dont know where to generate them on the linux box.

Also, I do not want to use any rhosts information. Since I have read about the holes in this form of security.

Any help would be greatly appreciated.
