Man ...
Write these rows to your server.cfg (and forget this bad password thing):
Code:
sv_rcon_minfailures 2
sv_rcon_maxfailures 3
sv_rcon_minfailuretime 30
sv_rcon_banpenalty 360
sv_rcon_log 1
sv_max_queries_sec 3.0
sv_max_queries_window 20
sv_max_queries_sec_global 2500
sv_max_connects_sec 2.0
sv_max_connects_window 4
sv_max_connects_sec_global 150
And ofcorse use strong rcon password, like this:
Thats all. The strong password never not be cracked if you protect your server with this extension:
