There is an update to the plugin - tested to generate
        SNMPv2 traps and
        SNMPv3 informs
    for the following platforms -
         Solaris 8
         Linux (RedHat 7.1)
         FreeBSD 4-stable
         NetBSD-1.5


Cheers

Gotta love open source response time.... That's about one day elapsed
time between request and implementation for a major new feature.
(Ok so they were probably working on it before.... ;-)

Can SNMP trapping be configured for Snort?  I would like to forward
alerts
to a central NMS console (HP Openview) via SNMP in leiu of the syslog
service.

Why yes, yes it can!   A newly checked into feature into CVS (through
the work of  Glenn Mansfield Keeni and K. Jayanthi allows one to use
either TRAPS or INFORMS.

Logging via SNMP isn't something I have done so this documentation
might be wrong.  i would appreciate any feedback.

Clip from the new ( 1.8.1 ) writing snort rules ( basically yanked from
the
source )

------------

The SNMP trap output module allows Snort to direct alerts to a network
management station (NMS). The MIB format is listed in the MIBS
directory of the Snort distribution. SNMP allows Snort to integrate
with many third party tools in a standard manner.

Glenn Mansfield Keeni contributed this plugin and established an SNMP
enterprise id for Snort (10234). This plugin is contains code licensed
under a BSD license and its copyright notice is listed in Appendix A

Format

trap_snmp: : alert, <sensorID>, {trap | inform}, \

             [SnmpOptions] , <snmptrapdAddress>, <community>

 alert specifies what type of events to relay to the NMS

 sensorID sensor name to differentiate multiple sensors

 trap use SNMP v2 traps

 inform use SNMP v2 informs ( the difference being that informs use
 acknowledgement from the NMS )

 SnmpOptions

 -v 2c SNMPv2 c community

 -p remote port number for trap recipient

 snmptrapdAddress Network address of SNMP reciever

 community SNMP community string

Example:
trap_snmp: alert, internal, trap, 192.168.1.10, private


Using generic trapping is fine, I haven't quick figured out how to do
it
yet.
