# This script is called by bro.rc at various points during the starting
|
|
# and stopping of Bro. This is presented as an interface into the start
|
|
# and stop process so that customizations can be made. Some simple
|
|
# examples are given as defaults.
|
|
|
|
# As these functions are within the same scope as bro.rc it is possible
|
|
# to alter variables that bro.rc needs to run properly. It is HIGHLY
|
|
# recommended that this not be done. If you do it don't ask why it broke
|
|
# because you were already warned.
|
|
|
|
# These functions should always return true so that bro.rc can complete
|
|
# and exit normally. If these fail to always return unexpected results
|
|
# may occur.
