Hi all!
=20
Thank you so much Jeff for your prompt reply, it was very useful.
=20
Now I have this other problem: I used traphandle to call a simple
program (of those that just say =93Hello Worl=94) 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=92ve seen that it=92s because my traphandler is not even being
called. Could somebody help?
=20
Here is my previous post for reference:

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.
=20
Previously, I successfully tested traptoemail in a Windows machine. I
just had to install ActiveState=92s ActivePERL and everything worked =
fine.
Now that I=92m testing on Linux I=92ve found some problems. What I would
like to know is how to install Perl correctly. Here is what I typed
during the installation:
=20
# ./configure --with-perl-modules --enable-embedded-perl --enable-shared
# make
# make install
# cd perl
# perl Makefile.PL
# make
# make install
=20
I don=92t know why traptoemail (neither any other Perl script) does not
work! For testing, I wrote a very simple Perl program like this:
=20
#!/usr/local/bin/perl
print "This is a test";
=20
And modified my snmptrapd.conf (located at /usr/local/etc/snmp) as
follows:
=20
traphandle default usr/bin/perl /usr/local/bin/Hello
=20
And ran my test again (forcing snmptrapd to use the recently created
configuration file):
=20
# snmptrapd -f =96Lo =96c /usr/local/etc/snmp/snmptrad.conf
=20
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?
=20
Thanks in advance for your time and attention.

IB
