Default Crawler Ping Question

There was a question of crawler pings on another thread but it did'nt seem to answer the question (maybe I just did'nt get it.)

If I recieve a ping w/ TTL = 2 and Hops = 0

A, If firewalled, what do I do?
B, If not firewalled, do I send a pong of TTL = 7 and Hops = 0
and and braodcast this ping with TTL = ? & Hops = ? to all
other connected servants?

I guess the root of my question is: If I dec TTL & inc hops and broadcast this ping, how do the servents receiving my broadcasted (crawler)ping know its a crawler if TTL = 1 & hops = 1?

A) If you are firewalled you dont send a pong for your host but you still forward the message to all clients who are connected to you.

B) I have the same question

Actually I found the answer shortly after posting this Msg.

to quote a portion of:
http://cvs.sourceforge.net/cgi-bin/v...ella/Draft.txt

***************
* An incoming Ping message with TTL = 2 and Hops = 0 is a
"Crawler Ping" used to scan the network. It and SHOULD be
replied to with pongs containing information about the host
receiving the ping and all other hosts it is connected to. The
information about neighbour nodes can be provided either by
creating pongs on their behalf, or by forwarding the ping to
them, and forward the pongs returned to the crawler.
***************

I read this to say 'if you get a ping w/ ttl = 2 & hops = 0 then respond with pongs conataining data about servants connected to you.'

At least thats how I see it. AND, I personally don't forward these pings. they stop w/ me (if i got one,it was meant for me, I respond & drop the ping).

Or am I wrong?
