Hi Tomas,

As far as I know, any UDP access needs root access.
(anybody, correct me if I'm wrong)
But you have a few options.
You can build a tool, which is installed with root privileges, like the
ping tool.
If you write a GUI application, you should have a look at AuthSample,
which brings up a dialogbox asking for an administrator name and password.
I do not know if there are any high-level services, which sends "known"
UDP packets.
You should think of it like this:
Is it possible for your application/tool to do any damage or behave in a
bad manner, such as pumping data out on the network, which uses a lot of
bandwidth, *then* you need to ask the administrator for permission.
-So if the owner of the computer can be accused for anything, he has to
"sign a paper", which in this case is a dialogbox. ;)
Love,
Jens
