Netty UDP and SNMP

[Tyler Durvik <ph...@gmail.com>]

I am trying to develop a program that receives SNMP messages over UDP port
161.  I have set up a Netty endpoint listening on port 161:

from("netty:udp://127.0.0.1:161?sync=false")
.log("NETTY")

When I run this, I never receive any data even though wireshark shows
packets coming in.  I have tried the same approach with mina2 with no
success. However, when I set up a snmp endpoint, data will be received by
Netty:

from("snmp://
127.0.0.1:161?protocol=udp&snmpVersion=1&delay=5&snmpCommunity=public&type=POLL&oids=x.y.z
")
.log("SNMP")

I verify this with the log messages.  I will receive "NETTY" log entries
but never see any "SNMP" messages in the logs.

Could someone explain why this is happening.

Can you try with 2.12 SNAPSHOT and use the networkInterface to specify
the network interface to join the existing multicast group.

See the page about the option.
