About Linux Process
The Linux Process action can verify that one or more particular processes are or are not running on a client system.
The Linux Process action provides these configuration elements and options:
- Continuously check the result and end the session if it changes
- SpecifiesEnabledorDisabled.WhenEnabled, if the client does not respond for five minutes, the server ends the session.
- Specifies a Boolean expression to use to check for a process. The expression can include these wildcards: * and ?, and parentheses ( ) to combine values, and the logical operators AND, OR, and NOT. This is the syntax for a process check expression:"process name" | (EXPRESSION) | NOT EXPRESSION | EXPRESSION AND EXPRESSION | EXPRESSION OR EXPRESSIONDouble quotes (" ") are required around each process name.
Here is an example expression:
"httpd" AND NOT "smtpd". Using this expression, the Linux Process action verifies that the HTTP daemon (httpd) is running on the system, and that the SMTP daemon (smtpd) is not running. Using another example expression,
("process1" OR "process2") AND "process3*", the action verifies the presence of either process1 or process2, and a process with a name that is process3 or starts with process3.
