sleep in asyncore

[billie]

Hi all.
I'm writing an authentication server by using asyncore / asynchat
modules.
I'd like to implement a basic brute-force protection by "freezing /
sleeping" the current client session for a period of time (e.g. 2
seconds) when the user sends a wrong password.
Does someone knows a "trick" to do that with asyncore?


Thanks in advance for your helping.

this could work:

add a timeout variable to your dispatcher instance, and have your "readable"
method returns False if timeout is set and the current time is before the given
value. then set the timeout value to time.time() + 2 when you see a bad pass-
word.
