From: deicher@sandia.gov Operating system: OpenBSD 2.6 -currrent PHP version: 3.0.14 PHP Bug Type: Misbehaving function Bug description: Invalid object identifier Using the snmpget function this will fail immediately with Invalid object identifier and nothing goes out the wire, BUT if you use the snmpwalk function the same error occurs but there is actually an snmpget function seen on the wire. (See net capture at end of entry, this is only a subset of the capture) PHP SCRIPT-------------------------------------------------------------------------- <?PHP /* ** Print SNMP Query */ debugger_on( "127.0.0.1"); $snmpdata = snmpwalk( "$hostname", "$read-string", "$oid"); for($x = 0; $x < count($snmpdata); $x++) { echo $snmpdata[$x].
