Hi,
I ran a soekris box as AP, and recently upgraded it from a very old 4.2, to 5.0
-current. It was running the old 4.2 for such a long time, since I only had a
32MB CF card in it, and just recently bought a new 2GB card, to install a full
system on it.
I have a ral wireless device in the box, configured as hostap:
# cat /etc/hostname.ral0
inet 10.23.4.56 255.255.0.0
nwid brb.freifunk.net chan 1 mediaopt hostap
The clients are OpenBSD notebooks. Now after the upgrade it happens after some
time (don't know what the timeframe is, maybe a day maybe longer or shorter,
the wireless is not that much used), that the ral device is not responding,
when a client tries to connect to the WLAN. On the client I see the status on
the WLAN device as status: no network
on the access point, all seems to be fine:
# ifconfig ral0
ral0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
lladdr 00:11:09:9a:9a:7e
priority: 4
groups: wlan
media: IEEE802.11 autoselect hostap (autoselect mode 11b hostap)
status: active
ieee80211: nwid brb.freifunk.net chan 1 bssid 00:11:09:9a:9a:7e 100dBm
inet6 fe80::211:9ff:fe9a:9a7e%ral0 prefixlen 64 scopeid 0x4
inet 10.23.4.56 netmask 0xffff0000 broadcast 10.23.255.255
To get it to work again, I have to login to the AP, and issue a
sh /etc/netstart ral0
that's all, afterwards, the client can happily connect.
When I have the problem, I watched with tcpdump what happens when the client
tries to connect to the network:
tcpdump -n -i ral0 -y IEEE802_11_RADIO -vvv
See the tcpdump output and dmesg below.
Suggestion to debug this problem?
Sebastian
