Hello,
I was really nerved when I noticed that rtadvd is exiting
without any notice if the host is not an ipv6 gateway.
Since it took me a lot of time to find this problem
I wrote a patch for rtadvd to show a message and
noticed something strange:
rtadvd won't exit even if ipv6 forwarding is not
enabled, take a look at this patch. (attachement)
Watch out for the changed if-condition.
Is that really a bug ?
The patch works fine for on freebsd 4.5-stable
using kame version 20010528/FreeBSD.
