[Olsr-users] Hop Count of data packets

[Bhat, Ishwara]

Hi,

 

I need to know how many hops a data has traversed over mesh. I know OLSR
control packets have hop count field. But what about data packets routed
on mesh?

 

I thought I could modify any data packet in the forwarding node (so as
to update the hop count). But application level does not have access to
packets destined for some other node.

 

Should this be done only by iptables and netfilter chains ? Or is there
any other way to do this?

 

Thanks,

Ishwar
