logging traps - traphandle calling Perl scripts

Hi all,
 
My name is Irving Barría, a panamanian student of electronics
engineering, in charge of a project regarding net-snmp. I have installed
net-SNMP 5.1.4 on a RHEL AS 3 system with kernel version 2.4.24 and I
can generate traps and also receive them in the same machine through the
loopback interface. As you can see, I’m just testing but there is a plan
to use net-snmp in a production system. First of all, I would like to
know how to log the traps that my machine receives. In my test I open a
terminal and type the following:
 
      # snmptrapd -f –Lo
 
After this, I open another terminal and type:
 
            # snmptrap -v 1 -c public localhost "" "" 0 0  ""
 
As long as I understand, the first command starts the trap receiver
while the later generates a ColdStart trap. In the terminal where
snmptrapd is running I can see the receipt of the trap but I can’t
figure out how to log them in some file of my preference.
 
=============================== One more question
=======================================
 
Previously, I successfully tested traptoemail in a Windows machine. I
just had to install ActiveState’s ActivePERL and everything worked fine.
Now that I’m testing on Linux I’ve found some problems. What I would
like to know is how to install Perl correctly. Here is what I typed
during the installation:
 
# ./configure --with-perl-modules --enable-embedded-perl --enable-shared
# make
# make install
# cd perl
# perl Makefile.PL
# make
# make install
 
I don’t know why traptoemail (neither any other Perl script) does not
work!  For testing, I wrote a very simple Perl program like this:
 
#!/usr/local/bin/perl
print "This is a test";
 
And modified my snmptrapd.conf (located at /usr/local/etc/snmp) as
follows:
 
traphandle default usr/bin/perl /usr/local/bin/Hello
 
And ran my test again (forcing snmptrapd to use the recently created
configuration file):
 
# snmptrapd -f –Lo –c /usr/local/etc/snmp/snmptrad.conf
 
And I can see the trap in the Terminal but no output from my Perl
script.
I have to mention that I after a long time testing I ended up installing
ActivePERL for Linux but nothing got better.
Could somebody help?
 
Thanks in advance for your time and attention.
 
Regards,
IB
