Security Considerations
Chapter 3 69
2. In the Scoping Pane, right-click the client(s) from which you want to
remove security and click Unsecure.
3. Click Yes to confirm that you allow access to the selected client(s).
If you want to remove security from all the clients in the cell, proceed as
follows:
1. In the Context List, click Clients.
2. In the Scoping Pane, right-click Clients and click Cell Unsecure.
3. Click Yes to confirm that you allow access to all client(s) in your cell.
The allow_hosts and deny_hosts Files
When you secure a client, the client names of the systems allowed to
access a client are written to the allow_hosts file. You can also explicitly
deny access to a client from certain computers by adding their names to
the deny_hosts file. These files are located in the
<AppRM_home>\Config\client directory.
Specify each client name in a separate line.
NOTE If you accidentally lock out a client, you can manually edit (or delete) the
allow_hosts file on this client.
The files are in double-byte format (Unicode).
Strict Hostname Checking
By default, the Cell Manager uses a relatively simple method for
validating users. It uses the hostname as known by the client where a
user interface or a ZDB Agent and VSSBAR are started. This method is
easier to configure and it provides a reasonable level of security in
environments where security is considered as “advisory” (i.e. malicious
attacks are not expected).
