Repository

The repository function runs on each system and periodically checks for new

messages from the administrator. It checks at a scheduled time interval or at the

occurrence of several interesting events (for example, boot, resume from suspend

or hibernate, detection of a new network adapter, and assignment of a new IP

address). The repository function looks for messages in a set of directories, in a

Windows share location, such as \\machine\share\directory, at HTTP URLs, and

at FTP URLs . If more than one message is found, it processes them in “directory

sort by name” order. Only one message is processed at a time. A message is only

processed successfully once. If processing a message fails, by default, it is not

attempted again, but retrying on failure can be specified in the message itself.

A message must be packaged by an administrator before being placed in a

directory to be processed by the repository function. To create the package, the

administrator places all of the files that constitute the message into a directory (or

its subdirectories). One of the files must be named go.rrs the primary command

script. The administrator can optionally use a signature key for this message, but if

used the key must be available to all of the target systems. The repository function

checks the package for integrity, checks the signature if supplied and unpack all of

the files into a local directory before executing go.rrs.

The primary command script file (go.rrs) follows the syntax of a Windows

command file. It might contain legitimate Windows commands and any of the

commands listed in the following section. Also, a Python command interpreter is

installed as part of the Rescue and Recovery environment, so Python scripts might

also be called from the go.rrs script.

At the end of execution of the script, all files unpacked from the message is

deleted, so if files are required after the script exits (for example, installing a patch

on reboot) the files must be moved out of the message directory.

Each system has a configuration of repositories to check. It might be appropriate

for the IT administrator to divide the population of systems into groups and assign

different repositories (network shares) to each group. For example, systems might

be grouped geographically by proximity to a file server. Or, systems could be

grouped by function, such as engineering, sales, or support.

Antidote Delivery Manager and Windows commands

The Antidote Delivery Manager system provides several commands to facilitate the

operation of the system. In addition to the command to create messages and adjust

settings, there are commands to control networking, determine and control

operating system state, examine XML files from system inventories, and notify the

user of progress of the Antidote Delivery Manager script on the client machine.

The NETWK command enables or disables networking or restricts networking to a

limited group of network addresses. The INRR command can be used to determine

if the Windows 2000, Windows XP or Windows Vista is running or if the computer

is in the Rescue and Recovery environment. The REBOOT command can be used

to shut down the computer and specify that it should boot either to Windows 200,

Windows XP or Windows Vista or to Rescue and Recovery. The MSGBOX

application allows for communication with the user by displaying a message in a

pop-up box. The message box can optionally contain OK and Cancel buttons so the

message can act differently based on input from the user.
