[Olsr-users] OLSR setup on XP/CE with iPhone, Vista and 802.11n thrown in

[Jeremy King]

Hello,

I've been trying to get OLSR to work on a number of machines, but I cannot
get packets forwarded. I've a number of questions.

Problem #1.
Here's my setup. All are on the same ad-hoc network, running WEP.
A. XP Laptop. Running Switch 0.5.5. IP address 192.168.0.2
B. XP Laptop. Running Switch 0.5.5. IP address 192.168.0.1
C. Win CE.    Running olsrd.exe 0.5.4.  IP address 192.168.0.3

In this setup, I have A <--> B <--> C. Devices C and A cannot see each other
directly, but see the other as a second off B Neither A nor C can ping each
other. Both can ping B, and B can ping them. Neither route table for A or C
include the other. How can I get A to talk to C? This is the route table for
A:

===========================================================================
Persistent Routes:
  None

I tried to use my iPhone (192.168.2.4) as a node in this network, as well,
but I removed it to remove another variable.

Problem #2.
Machine B, listed above, has a Ethernet connection to my intranet (with IP
192.168.0.38). How can I route default traffic from my mesh sub-net
(192.168.2.x) to my Internet gateway (192.168.0.1) on my Ethernet network.
Will having "HNA4 {0.0.0.0   0.0.0.0}" give me this route? and will adding
"192.168.0.0   255.255.255.0" in the brackets give me access to the
912.168.0.x subnet from the mesh subnet?

Problem #3.
I've tried to include two Vista machines, each running 802.11n. They can see
the other nodes, but the other nodes can't see them, and they can't ping
anyone. Is this a problem with mixing N and G? Or is it due to the problem
I've read with N not working in ad-hoc mode?

Other questions:
I've looked at the conf file that Switch can generate. It has the following
entry:
   # FIBMetric ("flat", "correct", or "approx")
   FIBMetric  "flat"
What does this do?

Whenever the Vista and CE machines start OSLR, I get "ERROR -
EnableRouter():" right after the interfaces detail output. When I stop OLSR,
I get "ERROR - UnenableRouter():". The XP builds do not have the message
showing up. I'm not sure what's not working, but I can't help but wonder if
it's causing/resulting some of my connection problems.

One of the things that I see when watching the debug output from the Vista
machines is comments about receiving TC/HNA from NON SYM neighbors. What
does it take to be a SYM or NON SYM node?

The Vista machines have "--- SPF-stats for 1 nodes, 0 routes
(total/init/run/route/kern): 7000, 0, 7000, 0, 0" in the DIJKSTRA area of
the debug output, while I never see anything on the other machines in this
area.

Sorry for all the questions. :-\
