SNMP Object Types

I am reading from a file of VARBINDS such as

procCrash,6,1,1.3.6.1.4.1.17163.1.1.2.5.1.2,OCTET_STRING,sport

I know I must be having brain freeze.. But why doesn't the below excerpt work ?

$oid = '1.3.6.1.4.1.17163.1.1.2.5.1.2'; $objtype = 'OCTET_STRING'; $process = 'sport'; .... -varbindlist => [$oid, $objtype, $process]

but this

-varbindlist => [$oid, OCTET_STRING, $process]

does.

Re: SNMP Object Types

The ASN.1 type "names" are exported as functions, not strings, by the Net::SNMP module. The functions return a numeric value representing the type. In your example you are passing a string to the "-varbindlist" when it expects a numeric value. What you need to do is execute the function named "OCTET_STRING" by doing something like:

$type = 'OCTET_STRING'; $objtype = &{$type}();
