*brctl showstp br0: I am using busybox version of brctl and it doesn't
support the showstp parameter.
Besides, the wireless connection is dead before I create any bridge.
*ebtables-save: No perl in this tiny system to run this script.
However:
# ./ebtables -L
Bridge table: filter
Bridge chain: INPUT, entries: 0, policy: ACCEPT
Bridge chain: FORWARD, entries: 0, policy: ACCEPT
Bridge chain: OUTPUT, entries: 0, policy: ACCEPT
# ./ebtables -t nat -L
Bridge table: nat
Bridge chain: PREROUTING, entries: 0, policy: ACCEPT
Bridge chain: OUTPUT, entries: 0, policy: ACCEPT
Bridge chain: POSTROUTING, entries: 0, policy: ACCEPT
# ./ebtables -t broute -L
Bridge table: broute
Bridge chain: BROUTING, entries: 0, policy: ACCEPT
*ip addr:
# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
2: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000
link/ether 00:20:4a:9d:00:8b brd ff:ff:ff:ff:ff:ff
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast
qlen 1000
link/ether 00:20:4a:9d:00:94 brd ff:ff:ff:ff:ff:ff
*ip route show table all:
# ip route show table all
broadcast 127.255.255.255 dev lo src 127.0.0.1
broadcast 127.0.0.0 dev lo src 127.0.0.1
local 127.0.0.1 dev lo src 127.0.0.1
local 127.0.0.0/8 dev lo src 127.0.0.1
127.0.0.0/8 dev lo
So the wireless is unable to get DHCP before any bridging is done.
iwconfig shows proper association with the AP.
Manually assigning IP address doesn't help: cannot ping or send/receive
any data.
This pathology is triggered by enabling CONFIG_BRIDGE_NETFILTER.
Thanks.
