#!/bin/sh
#
# This is a sample /etc/dhcpc/dhcpcd.exe script.
# /etc/dhcpc/dhcpcd.exe script is executed by dhcpcd daemon
# any time it configures or shuts down interface.
# The following parameters are passed to dhcpcd.exe script:
# $1 = HostInfoFilePath, e.g "/var/lib/dhcpc/dhcpcd-eth0.info"
# $2 = "up" if interface has been configured with the same
# IP address as before reboot;
# $2 = "down" if interface has been shut down;
# $2 = "new" if interface has been configured with new IP address;
# $3 (optional) = "-d" debug flag passed if dhcpcd daemon has been
# invoked with "-d" flag
#
# This script sources /var/lib/dhcpc/dhcpcd-<interface>.info which defines
# a set of variables.
# NOTE THAT THE DATA IN SOME OF THESE VARIABLES COME FROM
# UNTRUSTED SOURCES AND ARE UNCHECKED.
# The variables in question are HOSTNAME, DOMAIN, NISDOMAIN,
# ROOTPATH DNSSEARCH and DHCPSNAME. Enough quoting is done to ensure that
# execution of this script is safe, but beware if you pass the value of any of
# these variables to another shell or perl script - there is nothing to
# stop an attacker putting dangerous characters in these variables.
#
# This is important: if noglob not set a filename expansion metachar may be
# included in one of the variables set in the info file and executed
# if that variable is used.
# Try this to see the effect:
# TEST='*'; echo $TEST
set -o noglob
