Spawn snmptrap from python

Hi
I am trying to spawn an snmptrap from python but i keep getting the following error

Invalid version specified after -v flag: 2c -c public 192.168.2.162 SNMPv2-SMI::enterprises.3.1.1

here is the python code i am using

Code:

from subprocess import Popen
Popen(['snmptrap', '-v 2c -c public 192.168.2.162 SNMPv2-SMI::enterprises.3.1.1'])

When i test the same command from the shell like this it works
snmptrap -v 2c -c public 192.168.2.162 SNMPv2-SMI::enterprises.3.1.1

I tried to close the space between v and 2c so its like this -v2c but i still get the error.

I will appreciate it very much if you can help me correct this or point out to me what i am doing wrong.

Thanks
Kaf

I got this to work and this is the code i used

Code:

import subprocess
from subprocess import Popen, PIPE

path = "-v 2c -c public 192.168.2.162 '' SNMPv2-SMI::enterprises.3.1.1"
Popen(['/opt/csw/bin/snmptrap', '%s' % path], shell=True, stdout=PIPE, stderr=subprocess.STDOUT)

If anyone else has a better way of doing this i will appreciate if you can share with me

Thanks

snmpinform

SNMPTRAP(1)							     Net-SNMP							       SNMPTRAP(1)

NAME

       snmptrap, snmpinform - sends an SNMP notification to a manager

SYNOPSIS

       snmptrap -v 1 [COMMON OPTIONS] [-Ci] enterprise-oid agent generic-trap specific-trap uptime [OID TYPE VALUE]...

       snmptrap -v [2c|3] [COMMON OPTIONS] [-Ci] uptime trap-oid [OID TYPE VALUE]...

       snmpinform -v [2c|3] [COMMON OPTIONS] uptime trap-oid [OID TYPE VALUE]...

DESCRIPTION

       snmptrap is an SNMP application that uses the SNMP TRAP operation to send information to a network manager.  One or more object identifiers
       (OIDs) can be given as arguments on the command line.  A type and a value must accompany each object identifier.   Each	variable  name	is
       given in the format specified in variables(5).

       When  invoked  as snmpinform, or when -Ci is added to the command line flags of snmptrap, it sends an INFORM-PDU, expecting a response from
       the trap receiver, retransmitting if required.  Otherwise it sends an TRAP-PDU or TRAP2-PDU.

       If any of the required version 1 parameters, enterprise-oid, agent, and uptime are specified as empty,  it  defaults  to  1.3.6.1.4.1.3.1.1
       (enterprises.cmu.1.1), hostname, and host-uptime respectively.

       The TYPE is a single character, one of:
	      i  INTEGER
	      u  UNSIGNED
	      c  COUNTER32
	      s  STRING
	      x  HEX STRING
	      d  DECIMAL STRING
	      n  NULLOBJ
	      o  OBJID
	      t  TIMETICKS
	      a  IPADDRESS
	      b  BITS
       which are handled in the same way as the snmpset command.

       For example:

       snmptrap -v 1 -c public manager enterprises.spider test-hub 3 0 '' interfaces.iftable.ifentry.ifindex.1 i 1

       will send a generic linkUp trap to manager, for interface 1.

OPTIONS

       snmptrap takes the common options described in the snmpcmd(1) manual page in addition to the -Ci option described above.
