Strict route doesn't work

Hi everyone, I'm interested in making a program, be it a batch/C/VB or what not, which receives a list of IPs and a destination and sees if it is possible to send a ping through that route.
I haven't had success using strict route with the windows/DOS ping command, eg:

ping -k 10.0.0.254 ... www.yahoo.com
where the IP's i've supplied are actually the resulting IPs of "tracert www.yahoo.com"

could someone explain how the -k should be used or how a program like this can be made without having to learn a new programming language etc.?

Thanks alot in advance Smile
Michael

Many internet routers are set to silently ignore ping requests. When I tried it with the 4 addresses needed to reach my ISP's home page, I got "destination unreachable" for the whole host list and each one separately.

Anyway, pinging www.yahoo.com from my location takes 11 jumps, and the maximum number of ip addresses that Windows ping can accept is 9.

Microsoft Windows XP ping:-

-k HostList : Specifies that the Echo Request messages use the Strict Source Route option in the IP header with the set of intermediate destinations specified in HostList. With strict source routing, the next intermediate destination must be directly reachable (it must be a neighbor on an interface of the router). The maximum number of addresses or names in the host list is 9. The host list is a series of IP addresses (in dotted decimal notation) separated by spaces.

aye, but i also tried a strict route to a place that is 3 hops away from me and i could ping each of the routers en route (no pun intended)
i've been told lately that the strict and loose route bits have been deprecated in past years (over a decade supposedly) so it may not be an option to do what i want through the -k and -j switches, question is can i proxy ping from one router to a remote router according to a list of IPs (routers) so i can test a static path in a router network? The network is composed of Cisco equipment
