NAME

        AG_RFC3416_Trap - Trap Test

Purpose

        Verify that NUT playing the SNMPv2C agent can properly generate the
SNMPv2C-Trap PDU and sent it to the manager.

TARGET

        SNMPv2-Agent

SYNOPSIS

        * Setup


          Set the SNMP Agent1's (NUT) address as above mentioned Network
Topology.

TEST PROCEDURE

        This test sequence is following.

    SNMP Manager1 (TN)                       SNMP Agent1 (NUT)
        |                                      |
        |<-------------------------------------|
     OP1|   1. Send SNMPv2C Trap-PDU           |
        |                                      |
        |                                      |
        |                                      |
        v                                      v

        1. TN sends SNMPv2C Get scalar object to NUT by issuing SNMPv2C Get to
get sysDescr 1.3.6.1.2.1.1.1 in system group in MIB II.
        2. NUT replies SNMPv2C GetResponse with correct values to TN.

JUDGMENT

        OP1 TN received SNMPv2C response from NUT responding to SNMPv2C Get
scalar object request correctly.

        Received packet with
        1. SNMP version = 1,
           Community=same as NUT's SNMPv2C community 
           PDU type = A2
        2. Request-id is the same as the request id in the previously received
SNMPv2C GetRequest.
        3. Error-status must be equal to zero and error-index must be equal
zero.
        4. Value field is the system descriptor in system group of NUT with
correct syntax type and value within the defined range field.

TERMINATION

        None

# Sample configuration to make net-snmpd RFC 1213.

# opening up the default config is not an option from a security point.

# WARNING: If you uncomment the following lines you allow write access to your
# snmpd daemon from any source! To avoid this use different names for your
# community or split out the write access to a different community and 
# restrict it to your local network.
# Also remember to comment the syslocation and syscontact parameters later as

# System contact information
#

# It is also possible to set the sysContact and sysLocation system
# variables through the snmpd.conf file:

syslocation raycom office (edit /etc/snmp/snmpd.conf)
syscontact jiabwang (configure /etc/snmp/snmp.local.conf)
sysservices  72
#sysUpTime      Timeticks:(595637548) 68 days, 22:32:55

# Example output of snmpwalk:
#   % snmpwalk -v 1 localhost -c public system
#   system.sysDescr.0 = "SunOS name sun4c"
#   system.sysObjectID.0 = OID: enterprises.ucdavis.ucdSnmpAgent.sunos4
#   system.sysUpTime.0 = Timeticks: (595637548) 68 days, 22:32:55
#   system.sysContact.0 = "Me <me>"
#   system.sysName.0 = "name"

#   system.sysServices.0 = 72

# Process checks.
#
#  The following are examples of how to use the agent to check for
#  processes running on the host.  The syntax looks something like:
#
#  proc NAME [MAX=0] [MIN=0]
#
#  NAME:  the name of the process to check for.  It must match
#         exactly (ie, http will not find httpd processes).
#  MAX:   the maximum number allowed to be running.  Defaults to 0.
#  MIN:   the minimum number to be running.  Defaults to 0.

#
#  Examples (commented out by default):
#

#  Make sure mountd is running
#proc mountd

#  Make sure there are no more than 4 ntalkds running, but 0 is ok too.
#proc ntalkd 4

#  Make sure at least one sendmail, but less than or equal to 10 are running.
#proc sendmail 10 1

#  A snmpwalk of the process mib tree would look something like this:
# 
# % snmpwalk -v 1 localhost -c public .1.3.6.1.4.1.2021.2
# enterprises.ucdavis.procTable.prEntry.prIndex.1 = 1
# enterprises.ucdavis.procTable.prEntry.prIndex.2 = 2
# enterprises.ucdavis.procTable.prEntry.prIndex.3 = 3
# enterprises.ucdavis.procTable.prEntry.prNames.1 = "mountd"
# enterprises.ucdavis.procTable.prEntry.prNames.2 = "ntalkd"
# enterprises.ucdavis.procTable.prEntry.prNames.3 = "sendmail"
# enterprises.ucdavis.procTable.prEntry.prMin.1 = 0
# enterprises.ucdavis.procTable.prEntry.prMin.2 = 0
# enterprises.ucdavis.procTable.prEntry.prMin.3 = 1
# enterprises.ucdavis.procTable.prEntry.prMax.1 = 0
# enterprises.ucdavis.procTable.prEntry.prMax.2 = 4
# enterprises.ucdavis.procTable.prEntry.prMax.3 = 10
# enterprises.ucdavis.procTable.prEntry.prCount.1 = 0
# enterprises.ucdavis.procTable.prEntry.prCount.2 = 0
# enterprises.ucdavis.procTable.prEntry.prCount.3 = 1
# enterprises.ucdavis.procTable.prEntry.prErrorFlag.1 = 1
# enterprises.ucdavis.procTable.prEntry.prErrorFlag.2 = 0
# enterprises.ucdavis.procTable.prEntry.prErrorFlag.3 = 0
# enterprises.ucdavis.procTable.prEntry.prErrMessage.1 = "No mountd process
running."
# enterprises.ucdavis.procTable.prEntry.prErrMessage.2 = ""
# enterprises.ucdavis.procTable.prEntry.prErrMessage.3 = ""
# enterprises.ucdavis.procTable.prEntry.prErrFix.1 = 0
# enterprises.ucdavis.procTable.prEntry.prErrFix.2 = 0
# enterprises.ucdavis.procTable.prEntry.prErrFix.3 = 0
#
#  Note that the errorFlag for mountd is set to 1 because one is not
#  running (in this case an rpc.mountd is, but thats not good enough),
#  and the ErrMessage tells you what's wrong.  The configuration
#  imposed in the snmpd.conf file is also shown.  
# 
#  Special Case:  When the min and max numbers are both 0, it assumes
#  you want a max of infinity and a min of 1.

Comment 1 Jan Safranek 2009-01-20 14:03:40 UTC 
I am not sure I understand the report correctly. In the TEST PROCEDURE chapter, there is a simple call-flow, where NUT (i.e. RHEL 5.3/snmpd) sends trap to the test suite running somewhere. So far so good.

But just one line below the description says "1. TN sends SNMPv2C Get scalar object to NUT by issuing SNMPv2C Get ...". This PDU is not in the call flow. And why it should be sent???? IMHO the description does not fit to the call flow above. From the test output I guess that the test suite does not send any packet and it just waits for (any?) incoming trap.

I miss some indication what stimulates snmpd to send a trap - trap is notification, that 'something' happened. And the 'something' should be explicitly configured in snmpd.conf, together with trap target. E.g. if you add 'trap2sink udp6:[::1]:162 public' to your snmpd.conf, snmpd will send all traps as SNMPv2 traps to [::1]:162. 

You can configure various events, which shall be reported by traps, e.g. you can send a trap when amount of free disk space becomes lower than 100MB. See man snmpd.conf, section "DisMan Event MIB".

By default, snmpd sends SNMPv2-MIB::coldStart trap on startup, maybe it's enough for your tests. All you need to do is to set it's destination using trapsink, trap2sink or trapsess statement in snmpd.conf (depending if you want SNMPv1,v2 or v3 trap) - see appropriate man page.
Comment 2 Jan Safranek 2009-03-05 09:41:44 UTC 
guys, is here any progress on this test case? Did you manage to get a trap out of snmpd? Do you need any assistance?
Comment 3 wang jiabo 2009-03-19 04:58:20 UTC 
yes.the test suite did not send any packet and just waits for incoming trap.
I add trap2sink udp6:[::1]:162 public to snmpd.conf,
and run snmptrap -v 2c -c public udp6:[::1]:162 "" SNMPv2-MIB::coldStart
but the case still failed.

strange... could you please attach snmpd.conf, which generated such error?
Comment 6 Jan Safranek 2009-03-23 13:53:01 UTC 
looking into the code... I'd appreciate also output of "snmpd -f -Lo -Ddump,trap -d" (note the new '-d' parameter).
