# Manage Client Connections

You can control several aspects relating to clients connecting to the DIH. Use the following configuration parameters, which you set in the `[Server]` section of the DIH configuration file.

`RecvTimeout` | How long the DIH attempts to read an client index action before it times out. The default value is 60 seconds. A small value can improve the indexing speed, but might drop more actions.
`RecvDuration` | How long a communication between the DIH and a client can last (in either direction). The default value is 600 seconds. A large value allows you to index more data with each action.

You can also control the users that can perform index operations by using the `[AuthorizationRoles]` section of the configuration file. In particular, you might want to restrict the users that can use the `Index` standard role. For more information, refer to the DIH Reference.
