Oh worthy monks, I need help with this script. I have used the base code from the Net::SNMP description from CPAN and have modified it to take an interface index number and via an snmp get, get the interface description.
The script works good if I hard code the node and the interface, but if I try to pull the variables from another source and use the array the script bombs saying "Result ERROR:: No response from remote host 'MyNode'."

#! c:/perl/bin/perl -w
use strict;
use Net::SNMP;

    my $now = localtime(); # Time in a readable format
    my $logfile = "D:/perl_logs/IfIndex2IfDesc.out";  # For Troublesho

+ log file: $!";
    print logfile "\n";
    print logfile "************  Start of script :$now  **************

 #Create an array with the data passed through. Seperate & count indiv

        my $count = 0;
        foreach $element (@ARGV) {
        print logfile "$count,$element\n";
        $count += 1;
    }
  
   my $community = "public";
   $node = "MyNode";
   $interface = "25"; 
#     $node = ("$ARGV[1]");
#     $interface = ("$ARGV[3]");
     chomp ($node);
     chomp ($interface);
     
      my ($session, $error) = Net::SNMP->session(
      -hostname  => shift || $node,
      -community => shift || $community
   );

        print logfile "node:'$node'\n";
        print logfile "IF:'$interface'\n";
        
   if (!defined($session)) {
      printf("Session ERROR: %s.\n", $error);
      exit 1;
   }


   my $IfDescr = '.1.3.6.1.2.1.2.2.1.2.'.$interface;
  

   my $result = $session->get_request(
      -varbindlist => [$IfDescr]
       );
   
   if (!defined($result)) {
      printf("Result ERROR:: %s.\n", $session->error);
      $session->close;
      exit 1;
   }

   printf("Interface Description / Alias for host '%s' is '%s'\n",
         $session->hostname, $result->{$IfDescr}
   );
   print logfile ("Interface Description / Alias for host '$node' is '
+$result->{$IfDescr}'\n",
      );
   print logfile "\n";

     
   $session->close;
   
close logfile;
   exit 0;

Still a newbie at this and would appreciate the help.
