I have opted to go for Ubuntu in order to try to get this working.
 
I am at the same stage as before though, i can snmpwalk the firewall using 
version 1 but with version 3 i still get -
"snmpwalk: No securityName specified"
 
This is dispite me following the snmpconf command line tutorial and going 
through the "http://net-snmp.sourceforge.net/docs/README.snmpv3.html"; readme.
 
Something has gone wrong somewhere.
 
My snmpd.conf file within /usr/local/share/snmp contains the following: (Spam 
warning)
 
###########################################################################

# snmpd.conf

##########################################################################
# SECTION: Access Control Setup
#
#   This section defines who is allowed to talk to your running

# SECTION: System Information Setup
#
#   This section defines some of the information reported in
#   the "system" mib group in the mibII tree.
 
# syslocation: The [typically physical] location of the system.
#   Note that setting this value here means that when trying to
#   perform an snmp SET operation to the sysLocation.0 variable will make
#   the agent return the "notWritable" error code.  IE, including
#   this token in the snmpd.conf file will disable write access to
#   the variable.
#   arguments:  location_string
 
syslocation  home
 
# syscontact: The contact information for the administrator
#   Note that setting this value here means that when trying to
#   perform an snmp SET operation to the sysContact.0 variable will make
#   the agent return the "notWritable" error code.  IE, including
#   this token in the snmpd.conf file will disable write access to
#   the variable.
#   arguments:  contact_string
 
syscontact  1337
 
 
 
###########################################################################
# SECTION: Trap Destinations
#
#   Here we define who the agent will send traps to.
 
# informsink: A SNMPv2c inform (acknowledged trap) receiver
#   arguments: host [community] [portnum]
 
informsink  PIX  
 
# trapcommunity: Default trap sink community to use
#   arguments: community-string
 
trapcommunity  .1.3.6.1.4.1.8072
 
# authtrapenable: Should we send traps when authentication failures occur
#   arguments: 1 | 2   (1 = yes, 2 = no)
 
authtrapenable  1

Any help on this problem is appreciated - Was up all night trying to send an 
SNMPv3 packet.
 
Thanks in advance.
