SNMP trap listening on multiple ports in RHEL

[Haridas, Rijeshk (NSN - IN/Bangalore)]

Hello all,

Usecase:
A SNMP Network element send a trap to the standard port 162 in the RHEL
machine.Only one trap handler can bind to this 162 port at a time.
I want to forward/copy this trap to multiple ports like port1,port2,etc
besides the port 162 so that I can have multiple trap handlers in my
machine each independenly listening to its assigned port.All these ports
are in the same machine.
(ie,duplicate the trap in multiple ports for my applications to listen
).

Redirect using iptables only forwards trap from 162 to any one port we
configure.Also this listen only on the forwarded port and not on 162. 

Any ways of achieving this.



Warm Regards
