[luci] Luci richtig Konfigurieren

[Jo-Philipp Wich]

Hola,

I switch to english here, so that others have the chance to know what's going on in this
thread ;)

Okay, we just got a bunch of NanoStation2 devices and begun to deploy them in our mesh.
We experienced strange connection problems too and I debugged it a bit. Turned out that
madwifi and fragmentation settings for wireless don't play well together.

Before I removed the frag option from the wireless config, I was unable to exchange
packets larger then around 500 bytes. A typical symptom that occured when I tried to
access the web interface via wireless, was that the initial LuCI splash page appeared and
the connection then stalled forever after the redirect. Also it was impossible to
establish ssh connections from the wireless side.

The following shell commands fixed the issue for us:
root at 104-61-234-42:~# uci delete wireless. at wifi-iface[0].frag
root at 104-61-234-42:~# uci commit wireless
root at 104-61-234-42:~# wifi

Or if you prefer the web interface:
Netzwerk -> Drahtlos -> wifi0 (Network -> Wireless -> wifi0)
Remove the value of the "Fragmentierungsschwelle" (Fragmentation Threshold) option and hit
Save & Apply . This solved the connection problems.

Also keep in mind, that older Freifunk snapshots still had firewall issues with
masquerading. In recent builds we extended the Kamikaze firewall to handle masquerading
for outgoing zone traffic properly.

I'll commit the fragmentation fixes in a minute, it would be cool if you can try again
with recent snapshots from http://dev.luci.freifunk-halle.net/freifunk-snapshots/ .
