[Olsr-users] Hop Count of data packets

[Bhat, Ishwara]

I thought if data packet comes by virtue of my system behavior, I could
check the TTL field of the received IP packet (without having to
initiate trace route)... 

If I need to check how "far" a specified IP address is, when the network
is "quiet" wrt my system data, then I could do explicit trace route and
check the TTL in the response...?

I guess Henning and me were actually talking about the same thing :)
traceroute (the tool) uses exactly the TTL hop count field in ICMP  
packets.

good luck! :))
