RE: help - SNMP Trap manager registration and deregistrationdynamically...

Hi,

I had tried the below explained method, in a slightly different way, i.e:-

1. For adding/creating a new trap session, used api - create_trap_session(..),  instead of netsnmp_config(  "trapsink  localhost"  );. 
 2.And Removing the Notification receivers using snmpd_free_trapsinks(), as replied in the below mail.

But the problem here is snmpd_free_trapsinks(), is not removing the Recievers, but create_trap_session(..),  works properly.

Could you pls me know, if  these two api - netsnmp_config(), create_trap_session(..),behaviours are different, which makes snmpd_free_trapsinks(), works or not.
 
Thanks in advance.

Regards,
Kishore

The simplest way to add a trap receiver is probably to mimic the processing
of the config file entries, by calling

    netsnmp_config(  "trapsink  localhost"  );

with an appropriate config directive.

To remove *all* notification receivers, call

    snmpd_free_trapsinks();

Removing an individual trap receiver is going to be harder, since the
config processing routines aren't designed with that in mind.


And remember this will only work from the main SNMP agent.
It's not possible to manipulate the list of notification receivers
from an AgentX subagent (except by using the Target MIB)
