Net::Traceroute

[Wookie]

Quick question...

I was working on a program for quick testing of Network connectivity for a list of servers, so I wrote a forking monster that ran 20 chiildren at once, attempting connections with Net::Telnet and Net::FTP.

This was fine - until someone suggested adding Net::Traceroute to run a traceroute for each server. This was duly added, but unfortuantely once it was - the logging fron the job seemed to go nuts, and the only explanation that was offered was that Net::Traceroute somehow interferes with other versions of itself running if it's threaded?

Has anyone else experienced a problem like this - or could suggest what the problem is?

Sub used to run Traceroute:

---

# Subroutine check_tr
#
# Check Traceroute to host
sub check_tr {
   my ($server,$timeout)=@_;
   die("Insufficent Arguments passed to check_tr\n") unless (defined $
+timeout);
   my ($conn,$log);
   $log="Server $server - Traceroute - ";
   $conn=Net::Traceroute->new(host => $server,timeout => $timeout);
   if ($conn->found) {
      # Managed to trace
      my $hops = $conn->hops;
      $log.="Hops $hops\n";
   } else {
      $log.="*** FAILED TO TRACE ***\n";
   }
   return($log);
}

See eval with timeout, threaded perl.

As you use a timeouts there must be a alarm+sighandler somewhere in the code...
(Doesn't work fine with threads)
