traphandle does not work

Hi all!
 
Thank you so much Jeff for your prompt reply, it was very useful.
 
Now I have this other problem: I used traphandle to call a simple
program (of those that just say “Hello Worl”) called test and located at
/usr, compiled using gcc. It runs perfectly from the command line but
when I write traphandle  default /usr/test and a trap is caught by
snmptrad there in NO OUTPUT from my program. Previously I posted this
problem when running Perl scripts and I thought it was my installation
but now I’ve seen that it’s because my traphandler is not even being
called. Could somebody help?
 
Here is my previous post for reference:
 
 
=============================== One more question
=======================================
 
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.
 
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
