Hmm, no sure what is going on or missing from this, does anyone have a suggestion on how to resolve this??

That seems like an upstream issue with the source code itself, you may want to rerun make prefixed with LC_ALL=C so you get english error messages and then google for it, maybe you can find a patch for this problem, like here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=614439 or here: http://www.spinics.net/lists/netfilter- ... 19649.html

Related, if you want an easy way to generate packages from Perl modules from CPAN, try this: https://wiki.mageia.org/en/Perl_policy#Tools or this http://jquelin.blogspot.de/2011/06/cpan ... ageia.html

That type of error most commonly occurs due to a versioning problem among the various packages in the system.

Starting with a "make clean" might improve the situation, but more than likely there are some conditional compile statements someplace in the code that are not being properly satisfied due to version differences. I commonly encounter this type of situation when code developed on 32 bit is compiled on 64 bit, or vice-versa; the include files for the two architectures are NOT the same.

@Jim: Well, in this specific case i'd say this perl module is just totally outdated and broken, check http://search.cpan.org/~dpates/IPTables-IPv4-0.98/

Interesting question from my side would be, what do you need this particular module for, and what do you want to achive?

Yeah, that looks pretty outdated. Hence, versioning problems indeed.

Looks like some dev work will be required to use that package - if it is still needed. Given the age and how IPTables has grown, I don't think that I, personally, would want to bother with it.

Patches are also linked above

Yep, even more so when nftables will probably soon be the replacement for iptables when it receives wider adoption.

I will open an eLance project to get this to work in the morning. For anyone interested in getting paid for support, let me know, and I will gladly post the Project information on this case.

Thank you.

*shrug* I live in arizona and I make my living consulting. Where are you?

JIm,

I live in Pittsburgh, PA, however I am traveling on Business now in Aruba.

I think that this is really a small project, but I use consultants from time to time to accomplish specific goals.

Nice to meet you.

If anyone is interested in assuming this project (getting it to install on Mageia), I am interested in paying someone for their efforts. I have created a project on eLance, or I can work with you directly.

Maybe it's better to find a more recent drop-in replacement for this module?

If there would be a cost-effective drop in replacement, that would be fantastic.

I am using the IPTables::IPV4 module to provide support for the following functions:

$table = IPTables::IPv4::init('filter');

That's it! Is there another function which will provide a view of the IPTables filter?

I'm not into perl, but a quick search shows list function for at least: http://search.cpan.org/~jfried/Rex-0.43 ... ptables.pm

Thank you, but I think that the tools I am using that talks to the perl Modules needs more functions than this, But I always appreciate input and conversations.

Have a great day, I am working to get these issues closed ASAP.

On a related note, there are some patches in the bugreports against this module: https://rt.cpan.org/Public/Dist/Display ... ables-IPv4

That's it! Is there another function which will provide a view of the IPTables filter?

Well, you could use the perl system() function to directly access iptables via the shell functions.

For example:

Code: Select all

system("iptables -t nat -L");

which would list the ruleset that applies to the nat table.

As i examine the code that requires the IPTables function, There is much more than just the review of the existing IPTables functions.

Thank you very much for the response.
