Which is the version of your linux distro? Did you take a look at the man pages, to view the correct syntax in your case?: [code:1]man snmptrapd.conf

Could you try to run the command like:

[code:1]snmptrapd –authcommunity=”log public” -f -t -On -n -a -Lf logfile.txt -p pidfile -F “%02.2m/%02.2l/%y %02.2h:%02.2j:%02.2k %B %N %w %W %q %v n”

Probably if you use that command, you have to comment the [code:1]authCommunity log public line in the snmptrapd.conf file.

It is strange. By the way, which is your distro?

Looks like some dependence is missing.

Read the net:snmp manual: http://www.net-snmp.org/wiki/index.php/TUT:Configuring_snmptrapd

I’ve done a cpan install command but snmptrapd doesn’t work…

I think it’s a configuration problem. Could you help me to configure my snmp and snmptrap daemons.

I think this can be a problem with the version of Net-SNMP. Read http://linux.die.net/man/5/snmptrapd.conf

“Access Control

Starting with release 5.3, it is necessary to explicitly specify who is authorised to send traps and informs to the notification receiver (and what types of processing these are allowed to trigger). This uses an extension of the VACM model, used in the main SNMP agent.

There are currently three types of processing that can be specified:

log

log the details of the notification – either in a specified file, to standard output (or stderr), or via syslog (or similar).
execute

pass the details of the trap to a specified handler program, including embedded perl.

net

forward the trap to another notification receiver.
In the following directives, TYPES will be a (comma-separated) list of one or more of these tokens. Most commonly, this will typically be log,execute,net to cover any style of processing for a particular category of notification. But it is perfectly possible (even desirable) to limit certain notification sources to selected processing only.
authCommunity TYPES COMMUNITY [SOURCE [OID | -v VIEW ]]
authorises traps (and SNMPv2c INFORM requests) with the specified community to trigger the types of processing listed. By default, this will allow any notification using this community to be processed. The SOURCE field can be used to specify that the configuration should only apply to notifications received from particular sources – see snmpd.conf(5) for more details. ”

That is, looks like that authCommunity option si for Net-SNMP > 5.3

I don’t know if it’s possible to update the SNMP version (just to try).

Hi there !

I resolved my problem. The solution was in /etc/default/snmpd .
The variable “TRAPDRUN” must be “TRAPDRUN=yes” 😉

A Special Thanks to Raul
Thanks to manu 🙂

This afternoon I faced a similar problem, but it turned to be a bug in net-snmp in the 8.04 ubuntu server.
So I had to patch the sources and install net-snmp from the sources, a pain but it did work 🙂

Glad you fixed your problem
So long
