[Olsr-users] Olsrd cann't ping two-hops node - Nexus7

[Abubakr Ali]

Thanks Henning Rogge for your reply ..

Regards the route from node3 to node1, and at the beginning where all the
three tablets are close to, and in-range of, each others, I see the
following in the */proc/net/route* :

Destination==node1
Gateway==node1,
and ...
Destination==node2
Gateway==node2,

when changing the location of the tablets, then the routes change as follow:

Destination==node1
Gateway==node2,
and ...
Destination==node2
Gateway==node2,

accordingly, this mean that the HELLO and TC msgs are exchanged (i.e.: the
number-of-hops was calculated and that node1 is reachable through node2),
right ?

you sounded like if the default-values in the .conf file do not do me any
favor and that I have to hard-coded all the default-values myself, is that
true ?

Thanks,
Abubakr
