Installing ping_data.pl and traceroute.pl for PingER2

Install ping_data.pl

Ping_data.pl is a script that allows the collecting site to get the data from your site. ping_data.pl does not have to be installed on the same machine as pinger.pl (the script that makes the ping probe measurements), but the data file generated by pinger.pl must be visible on the machine running ping_data.pl, possibly via NFS or AFS.

• Get ping_data.pl and put it in the CGI directory for your HTTP server (often /usr/local/cgi-bin)
• You may already have cgi-lib.pl in your CGI directory. If not, put it there now.
• In ping_data.pl edit the line:
  require "/afs/slac/g/www/cgi-lib/cgi-lib.pl";
  to read:
  require "<cgi-path>/cgi-lib.pl";
  where <cgi-path> is the fully qualified path to your cgi-bin directory.
• Edit the line:
  $stats_dir = "/nfs/slac/g/net/pinger/pinger_mon_data";
  to read:
  $stats_dir = "<dir>/data"; where <dir> is the directory where your PingER data is stored.
• Edit the line:
  $sites_fn = "/afs/slac/www/comp/net/mon/offsite.nodes";
  to read:
  $sites_fn = "<dir>/beacons.txt
  The default for <dir> for PingER2 is /usr/local/share/pinger/beacons.txt.
• Make ping_data.pl and cgi-lib.pl executable with the command
• chmod a+x ping_data.pl cgi-lib.pl
• Test the script by visiting the URL http://yourwebserver/cgi-bin/ping_data.pl. A form should be shown allowing you to retrieve the raw data.

Install a Traceroute Server

While not strictly required for network monitoring, we are requesting that all collecting sites install a traceroute server.

• Put traceroute.pl in your CGI directory.
• Make it executable with the command
• chmod a+x traceroute.pl
• Test it by loading the URL http://yourwebserver/cgi-bin/traceroute.pl.
