Snmptrapd is not receiving generated traps in centos 5.7

Hi,

I tried to run snmptrapd from my customized service in centos 5.7 machine... the command used to start snmptrapd is ....

/opt/snmpdemo/bin/snmptrapd -Le -c /opt/snmpdemo/etc/snmp/snmptrapd.conf -n -C -t -m ""

And tried to trigger a trap... Trap got triggered but snmptrapd didn't receive it.... All the libraries are linked correctly....

is my command correct ? is snmptrapd got started ? or is there any other issue ?

Regards,
Sharath.
