How to find the port number on which my snmp is listening

[Naganarasimha]

I have a suse linux 9.0 with net snmp 5.1 I am able to enable the snmp in that machine and get the mib values thru snmp walk in the same machine   But if I try to see the mib values thru mib browser from some other PC I am not able too. I presume snmp is listening on some other port rather than in the default port 161.   Can some one give me some inputs to find in which port snmp is listening?   Thanks in advance, Naga
