Does anyone know the details of the flood timeout on battle.net?

Is there a set time that sends must be separated by?  Or is that set time determined by other variables, such as message size?

Thanks.

VB anti-flood.

Peering at the code:


   Const PerPacket = 200
   Const PerByte = 10


Self-explanatory IMHO.

The required amount of delay is calculated by both the size of the message(s) and the time in between the sending of the message(s).
Although there is no 100% accurate flood protection method, you should be a able to develop a rather decent one in an hour or so of experimentation.

Incorrect. To get 100% flood protection, don't send packets that count toward the server-side flood protection algorithm. Of course, this is quite limiting, but it works.

Somewhat obvious, don't send packets which are backed by flood control and you can't flood, but in that case flood protection would not be needed or even not existant.

Eh. I'll post it again.

61 or less in length (x<62)
4 seconds or more apart (4100ms)

Simple huh?
It works for me.
If you find something better let me know

Myndfyre,
Thanks for that implementation.  I will try that initially and see how it works out.

LoRd[nK],
I would love to experiment with this but from my experience, I'd get IP banned for 30 minutes if I flood even once.

The reason I asked for this is I intend on implementing a friend's list as a function on the bot which is analogous to the friends list hosted on bnet.  As you can see, !f m and !f l, could require quite a large number of packet sends/receives.

4 Seconds apart, this seems a bit high...
The amount of delay should be calculated based on last send time and the size of the last message, which is what the RequiredDelay algorithm does....

That is how it works..
I tested this a few months ago.
I don't know if new rules have been set.
If you want..
I could setup a bot to test my theories again.

Warcraft III has built in fool-proof flood protection. Works 100%. It's really fucking annoying, though.

Any idea how it works?  Is it a static or dynamic delay?

3150ms apart works fine to. I use it in my bot....

ah yes, I had forgotten about that.

You can send a message
over 200_TIMES spaced 3150ms apart?
Did you test it thoroughly?

If I had war3 I would test this myself.
