Hi again, By modifying the Udp port, I’ve succeeded to get an answer from snmpget -v 2c -c MyComRO system.sysLocation.0
But when I’m sending a request linked to my MIB. I still have the timeout. In order to know what part is not working correctly I typed the tcpdump -vv -i lo and the requests are sent and received at snmpd level. What’s wrong ? Do I have to configure it wit a specific option? Do you have a tips in order to fix it or a clue linked to the problem ? Thanks by advance.
