My Environment:
I downloaded and installed net-snmp5.4.2.1-1.win32.exe from sourceforge (needed a binary for windows that would work on Perl v5.8.9). I followed the README instruction to install the Perl modules:
ppm remove NETSNMP
cd (install folder)\Perl
ppm install NetSNMP.ppd
Test the install:
net-snmp-perl-test.pl
Result:
Testing translateObj
********************
Test passed. Result: .1.3.6.1.2.1.1.1
I test that my perl module is installed correctly:
perl -MSNMP -e 1

Issue:
Right now I am just writing some basic code to get the number of interfaces, and then print that number. I am getting nothing returned when I call $session->get. Here is my code. I am passing in the ip and the community string.

     use SNMP;
     $ENV{'MIBS'} = 'ALL';
     &SNMP::initMib();

     $session = new SNMP::Session(DestHost => $ARGV[0], Community =>$A
+RGV[1]);
     $numInts = $session->get('1.3.6.1.2.1.2.1.0');
     print "Number of Interfaces: $numInts\n";

When I run my code, I get:
Number of Interfaces:

I have tried a bunch of other things, but can't get it to return any values. If I just go to my commandline and type:
snmpget -v1 -c <community string> <ip> 1.3.6.1.2.1.2.1.0
I get results back as expected.....
