To configure authorized keys
1. Click SSH Authorized Keys under Configuration > Security and Access > Secure Shell
(SSH) in the tree view.
Note
If you previously configured authorized keys for user accounts, the information appears
in the View/Delete Per-User Authorized Keys table. To delete the authorized key for
each user click the Delete check box.
2. Select the user name from the Username drop-down list.
3. Complete the following, depending on the authorized key you are adding.
4. Click Apply.
5. Click Save to make your changes permanent.

Changing Secure Shell Key Pairs

The following procedure describes how to generate new RSA and DSA keys. When you
generate new keys, you might need to change configurations of each client, or the client might
return errors. For more information, see your SSH client documentation.
To configure key pairs
1. Click SSH Key Pairs under Configuration > Security and Access > Secure Shell (SSH) in
the tree view.
2. (Optional) To generate an RSA host key (to use with SSHv1), select the key size, listed in
bits, from the Generate New RSA v1 Host Key drop-down list.
Note
The most secure value is 1024 bits. Values over 1024 bits cause problems for some
clients, including those based on RSAREF.
3. Click Apply.

and an optional comment in the Add a New Authorized Key (RSA, for protocol version
1) table.
To add a RSA authorized key to use in SSHv2—enter the RSA key, in either OpenSSH
format or SSHv2 format, depending on your client, and optional comment in the (RSA,
for protocol version 2) table.
To add a DSA authorized key to use in SSHv2—enter the DSA key, in either OpenSSH
format or SSHv2 format, depending on your client, and optional comment in the Add a
