Sorry for late answer,
I just watch diald's debug message and found that when bind start, it
always send 45 byte request to root server. I blocked that package and
it just work. (Well, I stop using diald in auto-dial mode for a long
time.)
I think someone ever told me that the length of tcp's header is 40 byte.
Now the 45 byte package (40 bytes header + 5 bytes bind data) shouldn't
be able to contain much information. I think it's simply null request.
When bind send real query, the package's size should be longer than 45
byte.
Regards,
Joke.
