Well with thanks to mcummings for providing ebuilds for some nasty old perl modules, and ka0ttic pointing me in the right direction with some ebuild questions, I have got a working set of ebuilds for some network monitoring. In summary the network monitoring is done with flows sent to a central box that can then process them and present near real time graphs broken down in a variety of ways. I won’t bore you all with more, but I have written a HOWTO about this and if you are interested you can read it here. Suggestions / patches are welcome, either for the ebuilds or the HOWTO. The ebuilds are in my overlay but you are better off reading the HOWTO on how to install and use them.
Now some of my distractions are past I will see if I can get some real progress on the kolab ebuilds.
thanks!
