Hey.

I have a Freebsd server running freebsd-4.9-stable.
I cvsupped the ntop src last week for 3.1.1.

I then had no problems what so ever building ntop, except for the xml plugin saying it was not built, cause it cannot find
xmlversion.h, even though I have libxml installed, and specified the right paths to the .h. But that is not the problem.
Ntop runs and works fine on this box, not a single problem that I can see.

The problem is that, I have a few other servers, that I want to copy ntop too, but dont want to build it on all those boxes. I
created a tar with all the ntop binaries, as well as all the libraries that its linked too, as well as all the plugins that ntop
uses from both the /usr/local/lib directory as well as the plugins from the /usr/local/lib/ntop/plugins directory. I rebuilt all the
symbolic links for all the libraries and plugins and all the files that ntop was linked too. I have also checked all the permissions
on all the files and they are all the same.

One other thing, the boxes that I am copying ntop to, are almost exact duplicates of the first box that I built ntop on, and where
it works fine.

The problem is, when running ntop on the boxes that I copied it to, after checking all the permissions and links and everything, I
get these errors with regards to the plugins.

Tue Mar 1 05:37:16 2005 **WARNING** Unable to locate plugin '/usr/local/lib/ntop/plugins/icmpPlugin.so' entry function [Invalid

I have absolutely no idea how this has happened, and I have had this problem before, and not a single other person was able to help
me in any regards what so ever. I was hoping maybe someone would at least know what this error even means, so that I have some idea
of what I am meant to be doing to fix this.

If anyone has any idea, I would gladly apprecaite any suggestions.

Thanks
/Cole
