Hi,
If anyone is interested in testing out wireless mesh networking under
FreeBSD, the project has now reached a point where you can transfer

Always a good point to celebrate :)

I try to keep the branch in sync with head (sometimes more than)

$ svn co http://svn.freebsd.org/viewvc/base/projects/mesh11s/

weekly. The branch is located at the FreeBSD svn repo and everyone can

look at the code, mostly to try figuring out the scope of what layers

of svn (and if it matters, on a 5.5-S box):

sola% svn co http://svn.freebsd.org/viewvc/base/projects/mesh11s/
svn: PROPFIND request failed on '/viewvc/base/projects/mesh11s'

Not that I could run it now or even soon, but I'm interested in having a this is working at, and noting that this is my first ever attempted use svn: PROPFIND of '/viewvc/base/projects/mesh11s': 301 Moved (http://svn.freebsd.org )

Where to from here?  Might there be an old-fashioned tarball?

Sorry, what Brooks said.

To actually try out mesh networking you need ath(4) because ral(4) has

problems right now.


# ifconfig wlan0 inet w.x.y.z/q up

Channel discovery for mesh networks is not yet implemented, hence you

nodes must be on the same channel and same meshid, just like regular
AP operation).

After building and installing a new world and kernel, you need to do this: # ifconfig wlan0 create wlandev ath0 wlanmode mesh channel 1 meshid mymesh need to manually specify the channel on which the mesh is running (all

Not more like regular ad-hoc operation?

Yes, it's more like ad-hoc, but I was just illustrating a point for those that are more familiar with hostap networks having several nodes.

Pardon my ignorance. I've followed your later wikipedia links and many

others from there, but still haven't got much of an overview.  I'm a
little familiar with how OLSR works, and got some meaty clues reading
about the OLPC XO-1 use of their subset of 11s, but that's it so far.

Well, you can try google for more information. The links I emailed were accessible to almost everyone. If you have a PowerPoint file reader, you will find much more information related to 802.11s on the web.
