Are you sure that snmp agent listens on address that is accessible for snmp monitor? I.e., PC 1 (agent) address is 192.168.1.1 and PC 2 (monitor) address is 192.168.1.2. Snmp agent should listen on 192.168.1.1:161, while snmp monitor should send notifications to 192.168.1.1:161 (using its 192.168.1.2 interface).
If this is ok - check network connection between these two PCs, maybe there is a firewall on PC 1 that is blocking 161 port? If you work on linux, you can also use tcpdump to see what is going on network. -----Original Message----- From: Ver Allan N.

Cc: [email protected] Subject: RE: [SNMP4J] Trap Messages using SampleAgent from the network not working The thing is the traps and informs are received locally meaning on 127.0.0.1. When I use another machine to receive the traps, I cannot receive them. Let me elaborate further: Case 1: PC 1 - has snmp agent (SampleAgent from snmp4j source), has snmp monitor ----------------------- result: traps are received by PC 1. Case 2: PC 1 - has snmp agent (snmp4j agent) PC 2 - has snmp monitor ----------------------- Result: no traps received by PC 2 Btw, I didn't change anything in the SampleAgent source to make it run. -----Original Message----- From: Kazantsev, Andrey V.

Sumabat Sent: Friday, July 23, 2010 16:09 To: [email protected] Subject: [SNMP4J] Trap Messages using SampleAgent from the network not working Hi List, I'm having a problem trying to get trap messages over the network using the SampleAgent class. I tried starting it with the following argument: udp:127.0.0.1/161 Using the iReasoning MIBBrowser personal edition, I can receive trap messages locally. When I use another pc as snmp monitor, I could no longer receive those trap messages. I tried changing the program argument to udp:192.168.x.x/161 which is the ip address of the pc running the agent but still same result. Any ideas?
