15.1.7 Running Custom Scripts when a Conﬁgurator is Invoked

A conﬁgurator is responsible for reading the values in /etc/conﬁg/conﬁg.xml and making the appropriate changes live. Some

changes made by the conﬁgurators are part of the Linux conﬁguration, such as user passwords or ipconﬁg.

There are currently nineteen conﬁgurators, with each responsible for a speciﬁc conﬁg group (e.g., the “users” conﬁgurator

makes the user conﬁgurations in the conﬁg.xml ﬁle live). To see all the available conﬁgurators, type the following in a

command line prompt:

# conﬁg

When a change is made using the management console web GUI, the appropriate conﬁgurator is automatically run. This can

be problematic; if another user/administrator makes a change using the management console, the conﬁgurator could possibly

overwrite any custom CLI/linux conﬁgurations you may have set.

The solution to such a situation is to create a custom script that runs after each conﬁgurator has run. After each conﬁgurator

runs, it will check whether that appropriate custom script exists. You can then add any commands to the custom script that

will be invoked after the conﬁgurator runs.

The custom scripts must be in the correct location:

/etc/conﬁg/scripts/conﬁg-post-

To create an alerts custom script:

# cd /etc/conﬁg/scripts

# touch conﬁg-post-alerts

# vi conﬁg-post-alerts

This script could be used to recover a speciﬁc backup conﬁg, overwrite a conﬁg, make copies of conﬁg ﬁles, etc.

15.1.8 Backing-Up the Conﬁguration and Restoring Using a Local USB Drive

The /etc/scripts/backup-usb script has been written to save and load custom conﬁguration using a USB ﬂash drive. Before

saving the conﬁguration locally, you must prepare the USB storage device for use. To do this, disconnect all USB storage

devices, except for the storage device you wish to use.

Usage: /etc/scripts/backup-usb COMMAND [FILE]

COMMAND:

check-magic -- check volume label

set-magic -- set volume label

save [FILE] -- save conﬁguration to USB

delete [FILE] -- delete a conﬁguration tarbal from USB

list -- list available conﬁg backups on USB

load [FILE] -- load a speciﬁc conﬁg from USB

load-default -- load the default conﬁguration

set-default [FILE] -- set which ﬁle becomes the default
