TRASHIE  X11 thing is a bit of a pain for OSX as X11 never works as nice on OSX as Linux. Can't tunnel some X11 stuff on OSX at all. Of course X11 has it's benefits even on OSX and I can see why they keep it this way.

This is more for people trying to check network security and administrate networks than anything else so I can't see it being that popular mainstream anyway X11 or not.

Most of us who use it know about X11 and Linux/Unix anyway and probably should/do have it on a Linux box anyway but we love OSX so we try to put it here too. The lack of comments for this tells you mostly it is run on Linux and Win not OSX.

I can't find an app as good native to OSX but maybe there is one? But it is a wonderful project and application that really helps secure/admin networks.

ALCIMEDES  I downloaded WireShark today and must say that after the initial run through I'm very impressed.

Obviously a Win/Unix port based on appearance, but it can do what I've had a hard time finding any other free Mac app. capable of doing.

It's keeps detailed logs of all network traffic and displays them in a handy GUI interface.

If anyone is interested in where their traffic is going you should give this app. a shot.

I only took off points because the appearance is obviously not Mac standard which some people won't like, and quitting the app. required a force quit.

Considering what it brings to the table they are minor complaints though.
