IIRC, a bad WEP key will show up as "associated" but no data will be exchanged. Compile up wlanstats from /usr/src/tools/tools/net80211/wlanstats/ and run it - post the output here.

AFAIK WEP128 is different name for 104-bits key and that might be supported without need of wpa_supplicant. man ifconfig might shed some light. Although wpa_supplicant message states that it connected successfully to the network. Can you try to set the address by hand(taking some earlier info from windows machine)? Additionally you may try to use dhcpcd instead of dhclient(I suspect it's in ports). I remember some strange networks where dhclient had problems but dhcpcd worked fine.

I assumed you were, and had assumed your configuration may have been wrong. However, given your response, I assume you're using an "off the shelf" AP. There are several things that come to mind as to why you wouldn't get a DHCP lease, like MAC filtering as an example. You'll have to check the logs of the DHCP server to see if your requests are even making it to the daemon. tcpdump will come in handy if you have shell capabilities on your AP. > > For username/password prompt upon browser launch, you'll need to configure > > a reverse proxy to get a cookie upon successful auth to pass through the > > proxy. > > Could you please explain me how to do this? As for the proxy, you'll need to look at squid. I've personally never done what you need, but a buddy of mine has using squid. I can't give you any further details as the configuration/administrator of squid I know nothing about. I do know though that it has the capabilities you seek. ~Paul This message may contain confidential or privileged information.

Re: kern/162558: [dummynet] [panic] seldom dummynet panics
The following reply was made to PR kern/162558; it has been noted by GNATS. From: Eugene Grosbein To: bug-follo...@freebsd.org Cc: Subject: Re: kern/162558: [dummynet] [panic] seldom dummynet panics Date: Wed, 15 Feb 2012 19:25:43 +0700 Hi! The source of this problem seems to be famous 'dangling pointer' problem: - mbufs with packets from PPPoE users sometimes stall within dummynet queues, - then user disconnects, its ngX interface get destroyed, - then dummynet attempts to dereference its ifp pointer and panic occurs. There is workaround consisting of several tunnables eliminating races: - net.isr.bindthreads=1 in /boot/loader.conf; - net.isr.direct=1 and net.isr.direct_force=1 in /etc/sysctl.conf (default) Plus, use recent 8.2-STABLE as it contains some netgraph fixes for bugs that lead to panics in 8.2-RELEASE and early 8.2-STABLE versions. With these precautions I run my routers rock stable for months.

Very bad distribution of packets between multiple listening threads
Hi, I'm using FreeBSD 9-STABLE on a four core machine with bce to run multi-threaded unbound with libev (using kqueue). Here's the first message (not a long thread so far) about the problem: http://unbound.net/pipermail/unbound-users/2012-February/002237.html To summarize: whether I run unbound in multi-threaded or multi-process mode, I get very bad DNS query distribution between threads/processes. There is sometimes a 10-fold difference in the queries served (QPS) between threads (for example thread X gets 300, thread Y gets 3000). What could be done to make this distribution more balanced between threads? And where does this happens exactly?
