Server session policies

You can configure the following session policies on the BigFix® Remote Control Server to determine what actions and features are available during a remote control session. The policies can be configured initially when you create a user or target group. However, the permission links set up between the user and target groups determine what policies and permissions are finally derived for the session.

For more information about groups and policies, see the following sections.

Policy list definitions

Run post-session script

Determines whether a user-defined script is run after the remote control session finishes.

Set to Yes.

When a remote control session ends, the user-defined script is run. Complete the following steps to set up the scripts.

The script must be given the following name.

post_script. {ext}

Where {ext} is .cmd on a Windows™ system and .sh in UNIX™ or Linux™ systems.

The script must be placed in the following directory on the target.

Windows™ systems.: \%SYSTEMROOT%\scripts
Where SYSTEMROOT is the relevant Windows™ operating system directory.
UNIX™ or Linux™ systems.: /etc/scripts

Note: This directory must be owned by root and have the permissions 700 so that root can read, write, or execute. All other users must have no permissions. Otherwise, the script does not run and it fails. The success or failure of the execution of this script is logged in the audit log by the target.

Set to No.

No script is run after the session.

Run pre-session script

Determines whether a user-defined script is run before the remote control session starts. The script is run just after the session is allowed but before the controller user has access to the target. This policy is connected to Pre-script fail operation. The outcome of running the script and the continuation of the session is determined by the value that is set forPre-script fail operation.

Set to Yes.

When a Remote Control Session is requested, the defined script is run before the controller user has access to the target.

Defining Pre and Post scripts.

The script development is free from any constraint. Except for the need to allow them to run unattended and to use exit codes that can be correctly interpreted by Remote Control. Pre-scripts and post-scripts are supported on the following operating systems.

Windows® (XP, 2003, Vista, 7)
Linux® (SLES, RHLE)

When you develop scripts, you must adhere to the following rules:

Define the scripts as batch files on a Windows® system (with extension .cmd) and as shell files on a Linux® system (with extension .sh).
On Windows® systems, the scripts must be named pre_script.cmd and post_script.cmd. On Linux systems,™ they must be named pre_script.sh and post_script.sh.
Copy the scripts into a directory that is called scripts that is in the installation directory of the Remote Control target. Make sure that they are executable just by root to avoid security exposures in Linux®.
Note: This directory must be owned by root and have the permissions 700 so that root can read, write, or execute. All other users must have no permissions. Otherwise, the script does not run and it fails. The success or failure of the execution of this script is logged in the audit log by the target.
The pre-script and post-scripts are run with system privileges and without validation to protect them from unauthorized access.
Note: The installer creates the script directory with access just for administrators and localsystem on a Windows® system and for read/write/execute just for root on a Linux® system.
Ensure that the scripts end within 3 minutes. If they run for longer, they cannot return a valid execution code. The administrator at the controller is notified that the timeout elapsed and an error occurred. The execution code indicates whether the script did run.
Define a non-negative (greater than or equal to 0) exit code for the script to indicate that the script ran with success. Define a negative exit code to indicate that it ran with errors. Whenever an error occurs a message is reported to the controller. The exit code is shown and session fails to start.

Environment Variables

You can use the following environment variables in the pre-script and post-script.

RC_TIVOLI_ADMIN_NAME= Tivoli_administrator_name.

Where Tivoli_administrator_name specifies the Tivoli® administrator name on the controller as provided by the server.
