Meanwhile, my Tor *relay* is DOSing its own router. If anybody from
the Raspberry Pi thread is reading (and I'll post it there later if
not when I've observed it more), on 0.2.4.x, the Pi can handle most
circuit storms without crashing (though it still does, quite rarely),
but somehow it's causing my NAT router to partially/completely fail
and I still haven't figured out exactly how. It starts happening
*before* the ip_conntrack table is full, and it's considerably smaller
than the point at which ip_conntrack entries can trigger the OOM
killer, so I don't know yet what's causing it. The router has also
handled plenty more simultaneous in/out bandwidth in the past.
Regardless, the router starts dropping packets, and killing Tor stops
it, and restarting Tor soon enough (so most connected clients are
still in their retry period before giving up) starts it again immediately.
In fact, I've just woken up - started my Tor node a few hours ago
before going to sleep - and it appears to be starting to beat my
router down now. Router load isn't high, it doesn't seem out of
memory - when you can hit the status page - but ping times start to
climb or time out, and the first canary to fall over is DNS resolution
(the router "does" DNS via DNSmasq).

They're DDOSing *you*? How so?
