R: R: Problem installing nagios-plugins (1.4.1.1): Perl (Net::SNMP) not found but installed!

[GENTILUCCI Riccardo]

Ralph you're right..the encryption is useful for a snmpv3 environment (not mine)!!

I'll follow the way you've briefly described and start from an atomic environment to create the molecola NAGIOS!!

I really appreciate the kindness and courtesy of the members of this forum..

i hope I'll be able to be useful too sooner

Riccardo,

sorry, I wan't following your thread.

But I guess I know what you mean.

The problem seems to be that you followed two different
installation routes
that don't seem to care much about the other's standards.

I suspect that the perl-net-snmp rpm package doesn't really care
about your Perl installation
but only consults its rpm database to see if any of the rpm
prerequisite packages
(those that an "rpm -qpR
/some/path/perl-net-snmp.some_release.rpm" would list)
is already installed, and would reject installation (unless given
the --nodeps) altogether.

But I cannot say for sure because I install all the Perl modules
I would ever require
the Perl way (i.e. either via CPAN.pm or manually) instead of
using any rpms.

This way however, would probably also force you to build the
Nagios or any Nagios Exchange software
from the sources as well.
But it's more likely to work that way than depending on any
pre-built packages for any Linux
packaging system.

You could, if you required a consistent rpm database that also
comprises the Nagios SNMP plug-in stuff,
try to get so-called srpm package which really contain the source
tarball together with a spec file.
Install those like usual rpm files and change to /usr/src/redhat 
(I hope the path is correct, I only have few Linux boxes to
monitor and thus am seldomly exposed to RH)
I suggest you read "man rpmbuild" for how to build an RH rpm with
an adapted spec file from there.

Btw, do you really require Crypt::DES for your SNMP management in
your shielded LAN?
I may be wrong, but I thought encryption was only an option in
SNMPv3?
