[Olsr-users] Not getting any in packets (tables update) with two PC olsr demon setup
(spam-protected)
(spam-protected)
Fri Aug 21 08:46:42 CEST 2009
Hi,
Thanks for previous help.
I am getting the problems in two PC connection running the OLSR demon on
both.
PC1(10.105.12.201)<-------->PC2 (10.105.12.202)
I captured the packets using wireshark and at both machine we are able
to see the OLSR v1 packets of 20 length from each other. But we are not
getting any output in neigbor and link list OR any proff that both side
OLSR is running fine (If you know any other method to know that both
side olsr is fine, reply me.
When I am running the command ./olsrd -dispout, I can see the outgoing
packet display at screen but when I am running the ./olsrd -dispin
command then no packet is displayed.
I am attaching the log of the ./olsrd -dispin command at both PC1 and
PC2 and olsr.conf as below
Thanks in advance for any help/clue of the problem
How can we test that both side olsr is fine OR how can we get rid from
the problem of no display of pkt of -dispin command.
If you tell me then I can test your suggestion as well...
