They followed the instructions at Installation Overview.They were able to download and install the files. They then remotely logged in to test traceroute.pl file using http://202.12.103.71/cgi-bin/traceroute.pl which gives a webpage. This page looks correct, just tap yes to get it to make the traceroute. It also works if I VPN into SLAC from my home in the Bay Area. After pressing Yes I get:
It appears that though the request is being made to 202.12.103.71 when traceroute.pl at Amity tries to get the IP address of the traceroute server at Amity it gets 127.0.1.1. I suggest adding some debugging statements to traceroute.pl around line 84 (or you can use the perl -dT option (see the lines following line 2 in traceroute.pl)) which reads:
use Net::Domain qw(hostname hostfqdn hostdomain); my $hostname = hostfqdn(); my $ipv="4";#set default used by gethostbyname6 to decide if to force IPv6 my $ipaddr=gethostbyname6($hostname);
to trace what is happening and see if it is fixable (possibly hardcode the $ipaddr).
I would sort this out before going onto ping_data.pl.
