Hi Brian,

I'll try starting the switch with the arguments today.

I've always been using ngrep for tracing (sip) traffic, but somehow,  
it won't show ipv6 traffic :-/

Now, while typing this mail, I discover scripts/trace/sipgrep that  
comes with fs :-)

But it seems to also use ngrep, so it doesn't work..

Ah well, I'll try getting the trace from fs and play with this later.
