Well, it depends...

"Network Unreachable" can also mean that you have the right route and
some gateway host or network interface in the route is down.

"Time out" means some one in the path (either you or a gateway or the
remote host) is ignorant of the routing or it is down, and the down
state is not detectable.

If all you want is a program to test various routes for debug purposes
we have one for 4.2 BSD.  Perhaps if you mentioned the hosts involved,
someone may realize what your problem is.
