Re: Re: Send SNMP trap

The session is using SNMPv1. I tried changing OCTET_STRING to 0x01 and it ended in the same result.

Unknown ASN.1 type [0x01]

I am including the full code so anyone can take a look at what is going on:

use strict;
use Net::SNMP qw(:snmp);
my ($session, $error) = Net::SNMP->session(
                                           -hostname    => shift || '$
+host',
                                           -community   => 'public',
                                           -version     => 'snmpv1',
                                           -port        => shift || 16
+2
);

if (!defined($session)) {
    printf("ERROR: %s.\n", $error);
    exit 1;
}

my $svSvcName = '1.3.6.1.4.1.77.1.2.3.1.1';
my $message = "THIS IS AN SNMP TEST";
my @oids = ($svSvcName, "OCTET_STRING", $message);
#my @oids;

my $result = $session->trap(
                            -agentaddr    => '$monitor',
                            -varbindlist  => \@oids
                            #-varbindlist  => [$svSvcName, OCTET_STRIN
+G, "$message"]
);

if (!defined($result)) {

    printf("ERROR: %s.\n", $session->error);

    $session->close;

    exit 1;

}

$session->close;

Also I don't know if this is of importance but the script is running on a Windows 2000 machine with perl 5.8

That worked perfectly. I don't remember when I added the quotes to OCTET_STRING but that ridded me of the error. However what fixed the true proble was changing THIS: use Net::SNMP qw(:snmp); TO: use Net::SNMP qw(:asn1); Thanks for your help.	[reply]
