|
# PURPOSE: This script automatically removes the /etc/resolv.conf entries previously
|
|
# set by the companion script "client.up".
|
|
|
|
# INSTALL NOTES:
|
|
# Place this in /etc/openvpn/client.down
|
|
# Then, add the following to your /etc/openvpn/<clientconfig>.conf:
|
|
# client
|
|
# up /etc/openvpn/client.up
|
|
# down /etc/openvpn/client.down
|
|
# Next, "chmod a+x /etc/openvpn/client.down"
|
|
|
|
# USAGE NOTES:
|
|
# Note that this script is best served with the companion "client.up"
|
|
# script.
|
|
|
|
# Tested under Debian lenny with OpenVPN 2.1_rc11
|
|
# It should work with any UNIX with a POSIX sh, /etc/resolv.conf or resolvconf
|
|
|
|
# This runs with the context of the OpenVPN UID/GID
|
|
# at the time of execution. This generally means that
|
|
# the client "up" script will run fine, but the "down" script
|
|
# will require the use of the OpenVPN "down-root" plugin
|
|
# which is in the plugins/ directory of the OpenVPN source tree
|
|
|
|
# A horrid work around, from a security perspective,
|
|
# is to run OpenVPN as root. THIS IS NOT RECOMMENDED. You have
|
|
# been WARNED.
