> Table 14 Netlet Service Attributes

> Attribute | Default Value | Description
> --- | --- | ---
> Netlet Rules |  | Choose to add or delete a rule.
> If you add a rule, the following nine attributes are necessary:
> --Rule Name |  | Specifies a unique name for the rule.
> --Encryption Ciphers |  | Specifies the required ciphers.
> --URL |  | Specifies the URL to the application to be invoked.
> --Download Applet |  | Specifies if an applet needs to be downloaded. If an applet is used, the syntax in the associated edit box is: client port:server host:server port
> --Extend Session |  | Ensures that the Portal Server session time is extended while the Netlet session corresponding to this rule is running.
> --Local Port to Destination Port |  | Specifies client port, target host and target ports. After entering those values (in the next three rows of this table), click add to make them appear in the list.
> --Client Port |  | Specifies the client port on which the Netlet listens. For an FTP rule, the client port value must be 30021.
> --Target Host(s) |  | Static rules contain the host name of the target machine for the Netlet connection. Dynamic rules contain the word "TARGET".
> --Target Port(s) |  | Specifies the port on the target host.
> Default Native VM Cipher |  | Specifies the default cipher for the Netlet rules. This is useful when using existing rules that did not include the cipher as a part of the rule.
> Default Java Plugin Cipher |  | Specifies the default cipher for the Netlet rules. This is useful when using existing rules that did not include the cipher as a part of the rule.
> Default Loopback Port | 58000 | Specifies the port to be used on the client when applets are downloaded through the Netlet. The default value can be overridden in the Netlet rules.
> Reauthenticate for Connections |  | Ensures that users enter the Netlet password each time a Netlet connection needs to be established.

> Display Checkbox in Port Warning Dialog | Checked | Allows the user to suppress the warning popup.
> Keep Alive Interval (minutes) | 0 | Sets the time interval for which a Netlet connection is kept alive even if there is no operation. If you do not specify a value for this attribute, the idle Netlet connection times out with all other Portal Server idle connections per the "Max idle time (minutes)" value specified in the Session Attributes section of the Identity Server Configuration.
> Terminate Netlet at Portal Logout | Checked | Ensures that all connections are terminated when a user logs out of the Portal Server.
