[ANN] Rubyipq v0.1.0: Bindings for Netfilter's libipq

[Leonardo Eloy]

Hi there!

Rubyipq are Ruby bindings for Netfilter's libipq (ip queue), making it
possible for developers to intercept the incoming IP traffic, deciding
whether to accept or drop it (issuing a verdict) according to the
iptables rule set.

Project Homepage: http://rubyipq.rubyforge.org
Downloads (Source, Gem): http://rubyforge.org/frs/?group_id=959

Version 0.1.0 features:
* Built-in IP, TCP and UDP headers implementation;
* Possibility to obtain packet data;
* Implemented the whole ipq_packet_msg_t structure;
* Added the whole bunch of protocol numbers;
* Dynamic buffer size setting.

Installation from sources:
# tar -xzvf rubyipq-0.1.0.tar.gz
# cd rubyipq-0.1.0
# make
# make install

It's also available via RubyGems:
# gem install rubyipq

if you try to run the sample file and it cannot find the library, try
using something like this:
# export RUBYLIB=$RUBYLIB:/usr/local/lib/ruby/gems/1.8/gems/rubyipq-0.10-i686-linux/

I'm currently writing the manual and RDoc for this extension, I hope
in a week or so I'll have something ready. If anything goes wrong,
drop me a line, though. I'm also looking for someone to make a new
site for Rubyipq!

I have problem with the gem:

[gus@comp tmp]$ sudo gem install rubyipq

I modified the extconf.rb as followed for it to work:

-find_header("rubyipq_proto.h", ".")

+have_header("rubyipq_proto.h")

create_makefile("Rubyipq")

After this it compiled with no problem. I hope to get you some more
feedback. I think this will be a useful library for me.

Thanks,
Guillaume.

Yup, this is a sign of the problem described here:

Thanks a lot Guillaume, I'm correcting this issue right now.

Thanks again! Please send me a mail if you have any trouble getting it
to work or suggestions... I'll be kinda busy this weekend but I'll try
to finish the "manual" ASAP.
