Hi everyone,
Sorry in advance for my English, this is not my mother tongue.
This is the first time I post, and I'm having this problem for a long time.
My question is : Is there a way to get back Opaque:Float values with
SNMP4J ?
I'm asking that because I did some test with NetSNMP and it gives me the
following result (I replaced critical data with ###):
$ snmpget -v 2c -c #### 192.168.0.###
1.3.6.1.4.1.####.33.1.1.49.109.100.117.49
SNMPv2-SMI::enterprises.####.33.1.1.49.109.100.117.49 = Opaque: Float:
29.299999
[version 2C is used in the SNMPGET request]
But with SNMP4J, I don't know how to receive Opaque:Float.
I tried with the following Java code and I get the following error :
"java.io.IOException: Wrong ASN.1 type. Not a string: -97 at position 1"
[PDU uses Version 1]
+---------------code-------------------
public String getAnswer(OID oid) throws SNMPException,
IOException {
pdu = new PDUv1();
pdu.add(new VariableBinding(oid));
pdu.setType(PDU.GET);
ResponseEvent response = null;
response = snmp.send(pdu, target);
Opaque op =
(Opaque)response.getResponse().get(0).getVariable();
byte[] opByte = op.toByteArray(); // the content
is 1.3.6.1.4.1.####.33.1.1.49.109.100.117.49 = 9f:78:04:41:eb:33:33
ByteBuffer opByteBuff = ByteBuffer.wrap(opByte);
BERInputStream opBis = new BERInputStream(opByteBuff);
op.decodeBER(opBis); // Here is where I get the error
}
Thank you in advance.
