/// \file
/// \ingroup tutorial_net
/// This macro should be run together with authserv.C to test
/// authentication between two remote ROOT sessions.
/// Run first the authserv.C within a ROOT session on the server
/// machine, eg. "srv.machi.ne":
///
///          root[] .x authserv.C(3000)
///
/// authserv accepts as argument the port where it starts listening
/// (default 3000).
/// You can then run authclient.c in a ROOT session on the client
/// machine:
///          root[] .x authclient.C("srv.machi.ne:3000")
///
/// and you should get prompted for the credentials, if the case.
/// To start a parallel socket of size, for example, 5, enter the
/// size as second argument, ie
///
///          root[] .x authclient.C("srv.machi.ne:3000",5)
