in reply to Net::SNMP Query Returns Error: No response from remote host

Try adding debugging. For example:
#!/usr/bin/perl use strict; use warnings; use Data::Dump::Streamer; use Net::SNMP qw(DEBUG_ALL SNMP_TRAP_PORT); my $OID = '1.3.6.1.4.1.9.9.513.1.1.1.1.2.0.23.223.167.189.192'; my ( $session, $error ) = Net::SNMP->session( -hostname => shift || 'localhost', -community => shift || 'private', -version => 'snmpv2c', -port => SNMP_TRAP_PORT, -nonblocking => 1, -debug => DEBUG_ALL, ); if ( !defined $session ) { printf "ERROR: %s.\n", $error; exit 1; } my $result = $session->get_request( -varbindlist => [$OID], ); if ( !defined $result ) { printf "ERROR: %s.\n", $session->error(); $session->close(); exit 1; } $session->close(); exit 0;
