Traceroute.pl problems

Tests

• Does the form come up?
• Can one execute traceroute from the command line?
• Can one execute traceroute -I from the command line , it needs sudo?
• Can one execute traceroiute -m 30 -q 3 from the command line (see below)?. The option m gives the maximum number of hops, the option q gives the number of probes/hop.
• Is the server for traceroute.pl on a local address, for example does traceroute.pl?target=www.cern.ch gives:

  10.60.112.55 is a private address
  See The Naming System for information on host.domain and Addresses for information on Internet addresses.
  

• Does the pingserver work (see below)?
• Is there anything interesting in the web server log?
• The best thing to try next is to test traceroute.pl from the command line 
• In traceroute.pl try replacing exec($Tr, @Tr, $addr) with system($Tr, @Tr, $addr) == 0 or die "system($Tr, @Tr, $addr) failed: $?\n"; and test traceroute.pl from the command line as above.
• Create a simlpe perl script and execute from the command line and execute:

  #!/usr/bin/perl
  system('traceroute, -m 30 -q 1 -w 3, 134.79.197.200, 140') == 0 or die "system(' traceroute, -m 30 -q 1 -w 3, 134.79.197.200, 140') failed: $?\n"; exit;
  

Traceroute.pl  stops after 4 hops

Below is an example:
