Automated PerfSONAR Landmark finding

psonar_auto.pl

This script automates the whole process of finding new PerfSonar landmarks. It works as follows:

1. Fetch the list of all PerfSONAR sites from http://132.160.6.186/toolkit/gui/perfAdmin/directory.cgi
2. Find the sites that have working traceroute server.
3. Then find the sites that also have location information at http://ipaddress/toolkit
4. Compare the final list of working nodes to the ones in TULIP database to list the new sites.

The script is located at : /afs/slac.stanford.edu/package/pinger/tulip/psonar_auto.pl

Multiple text files are generated in the /tmp directory

• perfsonar_list.txt -> complete list of PerfSONAR sites
• perfsonar_list_working.txt -> sites with working traceroute server
• perfsonar_list_working_wl.txt -> sites with working traceroute server and location information
• perfsonar_list_new.txt -> working Perfsonar sites that are not in TULIP DB. This file is generated in /afs/slac.stanford.edu/package/pinger/tulip/ .The format is: ipaddr | city | state | country | lat | long

Since it requires access to TULIP DB, it must be run from pinger@pinger.
