First off, sorry to the list maintainer. I send this email
a few days
ago from the wrong email address, and it got that "this
list is
moderated email"
Ok, I've been tasked with setting up a number of embedded
devices to
broadcast a wireless network, with a fibre backbone and a
redundant
wireless link between nodes for redundancy.
Each "node" has two atheros cards in it, so unless
I'm mistaken, each
card will simply connect to the most powerful card it can
find, which
will be its mate in the same enclosure. Even if it does
connect to an
external "node", I can't have them connecting to
any node as this may
cause a loss
To get around this, I'll need to specify which MAC address
to connect to
I guess. I'm open to other ideas, but I can't think of any
other way
around this.
Is this something that can be set up using wpa_supplicant?
I'm assuming
that I cannot just "iwconfig ath1 ap
aa:bb:cc:dd:ee:ff" as
wpa_supplicant will change what I set.

In the config file use "BSSID=aa:bb:cc:dd:ee:ff"
Check the following link for complete information and
different network
configurations.

You can distinguish
connections by either bssid or ssid, in your case you only need the bssid.
Just configure the networks in the wpa_supplicant configuration file. ; If
you change the file on the file you can send a reconfigure to the supplicant via
wpa_cli. If you want even more dynamic access, build your own program to
communicate over the control socket and establish networks on the fly without
the config file. ; Either way works, I prefer using the control channel if
there are lots of dynamic changes.
Seems like you might need to get the scan results and pick
the one you want to associate so you can exclude the mac of your local
AP. I'm assuming all your SSIDs are the same. ;
One other method that might work. ; If you stick your local AP
information in the configuration file with bssid of your local AP in one
network config and another network config with just the SSID but with
higher priority, it shouldn't select your local one unless there are no APs in
range.
Cheers,
Bruce
