Hi all,

A couple of questions on Loose source routing...

1. Has anyone played with loose source routing on windows 2000?.. If so,
how do I specify a valid host-list in any of the tcp/ip commands like
tracert, ping, pathping.. etc...? (e.g. ping -j host-list destination). I
tried a comma or space delimited list and it didn't work, nor did a file
with the ips listed work.
2. Has anyone successfully probed a private network behind a gateway,
firewall or router appliance using loose or strict source routing? If so,
what tools / methodology has worked best?

I have been able to send packets to a host behind a Linux firewall with
source routing enabled (who would do that??) using the "sing" tool, but
the host on the other side was not able to communicate back to me... any
ideas?

Thanks
