I am currently doing a project regarding traps and would like to help me in this issue. I am knew to the trap world and thought that by posting this thread helps me move forward in this project.
First of all I will begin exactly from the very beginning, i.e. the net-snmp installation for monitoring.
Before setting up traps, I started in installing the SNMP agent on the machines I wanted to monitor. The machines consisted mainly of Solaris 9 and 10 machines. The installation was performed successfully and I managed to be able to monitor these machines via the cacti software (http://www.cacti.net/).
The configuration file for this daemon is the snmpd.conf file (attached). For traps the configuration file snmptrapd.conf was modified as per attached.
Now from here the headache starts…
I was able to know that traps were being sent since I was generating them (example, bring up the size of a harddisk, as set in the snmpd.conf) and viewing the traps in a WireShark trace. For your perusal I have also attached a trace when a trap was sent, after the size of the harddisk exceeded the size sent in the configuration file.
What I would like to understand is the amount of OID shown in the trace (HDD full.txt)
This leads me to the problem I have at the moment, I need that the trap receiver machine senses the trap received and sends an email. In the attached file, snmptrapd.conf I did the traphandle command that it is suppose to handle the selected OID, but if I put the above OID (1.3.6.1.4.1.2021.9.101.1 – HDD size) the trap does not work. It only worked as per below:
Do you have any ideas of how I can set up these default traps to be able to be sent to the trap receiver machine?
Is there any other way to configure the trap receiver daemon (snmptrapd.conf).
Hi,
I am writing a program in java to simulate a trap being sent from a device. I came to know that rawsocket cant be opened in java. Is there a provision to do in java?

Hi all,
I'm after a linux utility that can relay all incoming traffic on a certain port to another server. Can anyone recommend a good program?
I've taken a look at snmptrapd, but it's not obvious how this can be configured for my requirements.
Many thanks. (1 Reply)

NETSNMP_TRAP_API(3) Net-SNMP NETSNMP_TRAP_API(3)NAME
send_easy_trap, send_trap_vars, send_v2trap - send TRAPs or INFORMs from a Net-SNMP MIB module
SYNOPSIS
#include <net-snmp/agent/agent_trap.h>
void send_easy_trap(int trap, int specific);
void send_trap_vars(int trap, int specific, struct variable_list *vars);
void send_v2trap(struct variable_list *vars);
DESCRIPTION
These three routines may be used to send traps from a MIB module within the Net-SNMP agent (including an AgentX subagent).
send_easy_trap() sends an SNMPv1 trap (or the SNMPv2 equivalent) to the list of configured trap destinations (or "sinks"), using the pro-
vided values for the generic trap type, and specific trap value.
send_trap_vars() is similar, but appends the supplied list of variable bindings to the traps that are sent.
send_v2trap() uses the supplied list of variable bindings to form an SNMPv2 trap, which is sent to SNMPv2-capable sinks on the configured
list. An equivalent INFORM is sent to the configuredq list of inform sinks. Sinks that can only handle SNMPv1 traps are skipped.
The various "send_trap()" calls allow you to specify traps in different formats. And the various "trapsink" directives allow you to spec-
ify destinations to receive different formats. But *all* traps are sent to *all* destinations, regardless of how they were specified.
I.e. it's
___ trapsink
/
send_easy_trap ___ [ Trap ] ____ trap2sink
___ [ Generator ]
send_v2trap / [ ] ----- informsink
____
trapsess
*Not*
send_easy_trap -------------------> trapsink
send_v2trap -------------------> trap2sink
???? -------------------> informsink
???? -------------------> trapsess
WARNINGS
These routines are used to send the traps immediately they are called. Invoking them at the appropriate time is left to the MIB module
programmer.
