Hi,
I think you are trying to sent an IPv6 address as IpAddress BER encoded
on the wire. This is not possible, because the SNMP standard defines
IpAddress as IPv4 address and nothing else.
If this worked with 1.0 then this was an error in 1.0.
Best regards,
Frank

Hi,
I'm using the following code to create the target address.
Address targetAddress =
GenericAddress.parse("udp:<HostName>:<TrapReceiverPort>/162");
This goes through fine when I use the snmp4j1.0.jar. However, this
particular version seems does not support the IPv6 addresses. For IPv6
requests it throws the java.nio.BufferOverFlowException.
java.nio.BufferOverflowException

To fix the above issue, I picked up the latest jars snmp4j2.1.0.jar,
snmp4j1.11.3.jar, and snmp4j1.10.jar. All of these throw the unknown host
exception. What I notice is that snm4j sends hostname as
"hostname:trapreceiverport" to underneath java api to resolve the address,
hence the issue unknownhostexception. The same code works with 1.0 version
of jar. Are there any difference from now and then? Any help is very much
appreciated.
Thanks,
Parash
