I'm running the soekris with a custom kernel, basically derived from a
Red Hat 9 distro (2.4.22).
I copied the relevant glibc files (from the i386.rpm ) and compiled busybox.
I'm using the "vanilla" ip from the iproute rpm as well as bridge tools.
I compiled the kernel with basically evecrything modularized. (mostly
the netfilter stuff)
For the radio I'm using senao 200mW cards (NL-2511CD plus ext2) and 24dB
semiparabolic antennas from hyperlink.
Instead of the usual init startup debauchery I just put in busybox as
init running a simple /etc/rcS script which loads modules, starts syslog
(in circular buffer mode) and configures ip and bridge.
On some links I bridge with wds, on other I do it with proxyarp and on
some i route.
One trick is mounting everything read-only, basically means having a
directory with what you want read-write and mounting a tempfs somewhere,
copying the dir there and symlinks to it.
The longest link we've set up rums somewhere over 12 miles, with others
running 8, 10 miles.
In the co. where I work we're about to release (gpl) a distro for this
nice device (i mean, the soekris) which is a lfs distro, (we're
experimenting with linux 2.6.x) and the most "innovative" part is that
we've disposed of the whole init stuff instead we boot staight into perl
:) and there's a nice web configurator about to be ready. I'll send the
link as soon as it's posted.
oh!, and we're using hostap as the radio driver.
2 interesting facts:
1- just testing (not for production) we've established a 20 mile link.
2- it seems that the antennas far exceed the beam angle spec, we've
succesfully set up a link to a previously set up link far off the line
of sight (like 20 degrees, some 5 miles from the AP)

>I saw your post on the Soekris list. Unfortunately, I can't really offer much help on your question to the list regarding a host AP extension. I am trying to implement a point-to-point wireless link and was curious about what sort of configuration that you found successful for your point-to-point links and what transmission distance you achieved. Were you bridging from the wired to wireless links? Did you use Pebble? Have you publicly posted your network configuration files anywhere?
