# 16.7. Ssh2 Per-User Configuration

1. Create your private & public keys of local, by executing:

                [root@deep] /#su admin
                [admin@deep /]$ ssh-keygen2

                Generating 1024-bit dsa key pair
                6 Oo..oOo.oOo.
                Key generated.
                1024-bit dsa, admin@deep.openna.com, Sun Feb 13 2000 05:33:38 -0500
                Passphrase :
                Again      :
                Private key saved to /home/admin/.ssh2/id_dsa_1024_a
                Public key saved to /home/admin/.ssh2/id_dsa_1024_a.pub

2. Create an `identification` file in your `~/.ssh2` home directory on local:

                [admin@deep]$cd ~/.ssh2
                [admin@deep ]/.ssh2$echo "IdKey id_dsa_1024_a" > identification

   > : It's optional to create an identification file on Remote. The identification file contains the name of the private key that is to be used in authentication.

3. Copy your public key of Local id_dsa_1024_a.pub to `~/.ssh2` home directory of remote under the name, say, `Local.pub`.

4. Create an `authorization file` in your `~/.ssh2` home directory on remote:

                [admin@remote ]/.ssh2$touch authorization

   > : The `~/` means the user home directory.

5. Add the following one line to the `authorization` file on the remote host:

                [admin@remote ]/.ssh2$vi authorization

                key                     Local.pub
