Re: [Wing] How to use multi-radios

2011/5/6 Roberto Riggio <roberto.riggio@create-net.org>

The following is our deployment (case1):
A. With 1 NIC on channel 1, and is able to connect to Internet.
B. With 2 NICs on channel 1 and 6, respectively.
C. With 1 NIC on channel 6.

Links between PC A and B are work correctly,
all node information in lt.hosts, lt.links and lt.routes are found.

But the links between PC B and C are strange,
lt.hosts, lt.links are exist(both forward and backward are exist),
and metric on each link seems normal(around 1000~2000),
but we can not find any information about lt.routes.

Is there anything I may lost?

cound you send me the output of the following handlers:

read_handler lt.hosts
read_handler arp.table
read_handler lt.routes
read_handler lt.interfaces

read_handler wr/es/es_N.bcast_stats

where N=1,2

After experiment describe above, we try another scenrio.

The following is our deployment (case2):
A. With 1 NIC on channel 1, and is able to connect to Internet.
B. With 2 NICs on channel 1 and 6, respectively.
C. With "2 NICs" on channel "11 and 6", respectively.

In this case it work correctly,
we can use ping to access outside Internet (8.8.8.8).

what do you mean that it works? Is that, from node A you can
see routes to node C?

 Node C can see routes to node A, and can get ICMP reply from node A and Google DNS.

We guess:

If we want to use multi-channel, PC C's first NIC channel must match PC B's first NIC channel.
Even PC C's first NIC channel match PC B's "second" NIC channel, there is no connection between C and B.

This was a bug that should be solved since a few weeks. Are you using a recent build?

In any case could you provide me with the value of the aforementioned handlers
for your 3 scenarios?

Are you using openwrt or are you following the instruction for using wing over a pc?

In the latter case the script in the repository uses only one wireless interface. Could
you send me the file /tmp/clickd.click?

We use "git clone git://github.com/rriggio/click.git" to download the wing source code today,
and compile it on Fedora, then copy the necessary files to openwrt.
The others are following http://www.wing-project.org/software:notebook

We had modified the script clickd following
http://diana.create-net-ml.org/cgi-bin/mailman/private/wing/2011-March/000049.html

We have no those device now, can we send those files latter? (maybe on 5/9)

Thanks
