**Script and Website for live NS0 data driven Smokeping configuration file generation**

== Smokeping / Monitorung URL ==
[[http://frontline.paketsequenz.de/smokeping/smokeping.cgi | Smokeping for OpenNIC on Paketsequenz]]

== Script ==
This script generates the Targets file for /etc/smokeping/config.d on a Debian squeeze box. The shown smokeping Installation on the URL above is generated. This is still development Quality software/website!

# This script assumes the following hostname format for Tier 2 Servers
# Servername(nsX).State(NRW).Country(DE).DontCare
#
# And outputs a Targets file for smokeping

# Whats the IPv4 address of NS0?
NS0="75.127.96.89"

# Where can we store some tmpfiles?
TMPDIR="/tmp/"
