Enable_Control

Enable_Control_Msgs


Used for:	RTclient, RTserver, RTmon, and RTgms processes
Type:	String List
Default Value:	`echo`, `quit`
Valid Values:	Any valid command name or names, separated by commas (,) `_all` `UNKNOWN`

The Enable_Control_Msgs option is a string list specifying the commands allowed in a CONTROL message. The default allows the inclusion of the echo and quit commands in a CONTROL message. When this option is set to UNKNOWN, all commands (including echo and quit) are disabled. Setting this option to _all allows the inclusion of all valid commands in a CONTROL message.


	If an item in the list is prefixed with '!', then the behavior is negated. For example, the value "!setopt,_all" would allow all control messages except setopt.

Security-conscious sites should set this option carefully, as inadvertent or malicious misuse can cause damage to the system, the data, or the application. There are several commands that may be dangerous when executed. Specifically, the alias, connect, disconnect, retrieve, setopt, sh, source, subscribe, unalias, unsetopt, and unsubscribe commands should only be specified with extreme caution.


	The value `UNKNOWN` is a keyword. Do not enclose it in double quotations characters (")

A warning is emitted upon rejecting a control message.
