Your question is not very clear to me. Are you asking if it is
possible to set the TTL of an IP packet?
If so, and you are using Mac OS X, you should be able to do that with a
socket option, viz:
optval = Your_desired_initial_TTL;
retval = setsockopt(skt, PF_INET, IP_TTL, &optval, sizeof optval);
...
When you do this, the value Your_desired_initial_TTL is used as the TTL
in each packet that is transmitted via this socket.
Intermediate routers only decrement the TTL by 1 (these days); they
don't reset the value.
If that is not your question, perhaps you can rephrase it.
Regards,
Justin

I feel setting hop count doesnt works as it is dependent on the
immediate
router.
i.e. ur request will be forwarded to next router on by the router. This
cannot be set at application layer.
Can any body help me out ?
