Introduction
There are many things that may influence the quality of a BF2 server. One of them is the ping of the players. Playing against a lot of players with very high ping is straight out frustrating. Therefore a lot of server-operators choose to kick players with high ping, and the best way to do it is of course to do it automatically.
With that in mind, we at Battlefield.no have developed a ping kick script that solves this problem on our servers. And hopefully it can be of use to the rest of the community as well.
Current version is 1.2, added 2005-07-03.
Features
What the the ping kick script can offer is to
- kick people with high ping based on
- a configurable pinglimit
- after a configurable number of warnings (that only appear in the debug log on the server, if enabled)
- with a configurable interval between ping checks
- wait until a player has started playing before checking his/her ping, to avoid kicks on mapchange etc
Getting Started
To get started with the ping kick script you need to:
- Download the script here, and rename it to pingkick.py.
- Place it in the admin/standard_admin directory in your BF2 directory.
- Place the following code in the admin/standard_admin/__init__.py file in your BF2 directory:
import pingkick pingkick.init()
For these changes to take effect you will need to restart your BF2 server.
The Ping Kick Script
This is the ping script as we use it at Battlefield.no. Feel free to copy it, and since this is a wiki, feel free to modify it. But we would be very grateful of you appended a note to the updates section if you do.
Configuration
The ping kick script comes with four settings you can change:
autokick = 1 # Enables/disables autockicking pinglimit = 150 # The ping limit, obviously ;-p warnings = 3 # The number of warnings a player get before being kicked interval = 30 # The interval between ping checks
You can either change these settings directly in the script, or you can make sure there exists a dictionary in the bf2 object, called adminoptions, with the following keys:
pk.pingAutoKick pk.pingLimit pk.warnings pk.interval
If they exist, they will override the defaults set in the ping kick script. If you use our modified admin script, the adminoptions dictionary is made available, and populated with the values in the adminsettings.con file. So remember to add the above keys with appropriate values to the file. See here for more details on that.
Output
There ping kick script prints a variety of messages, but to actually view them you will need to enable debug-logging. This is done by
- setting g_debug to 1 in <bf2>/python/bf2/__init__.py
- enabling a writer, like we've done in modified admin script
When a player is cought by the ping kick script with a ping that is too high, a message like the following is logged:
[2005-07-03 04:44:28] PINGKICK: Player Panic[bf2.no] has exceeded the ping limit 2 time(s)
And when a player has been issued the maximum number of warnings, and is being kicked, a message like the following is logged:
[2005-07-03 04:44:43] PINGKICK: Kicking player Panic[bf2.no] for high ping ([120, 118, 118] > 100)
The numbers inside the braces are ping values that has been detected and that are in violation of the ping limit. And the number to the right of the greater than sign is the ping limit.
And five seconds before a player in violation of the ping limit is being kicked, a message like the following is printed in-game:
BF2.NO PING KICKER: Kicking player Panic[bf2.no] for high ping. (Limit is 100, player caught with [120, 118, 118].)
Again the numbers inside the braces are ping values that has been detected and that are in violation of the ping limit, and the first one is the ping limit.
The Code
# ------------------------------------------------------------------------
# Module: pingkick.py
# Authors: Kybber and Panic, Battlefield.no
# Version 1.2
# Description:
# This script kicks players with high ping, based on three different
# settings in the file 'adminsettings.con', loaded by the modified admin
# script (sv.adminScript = bfno_v1.1.py). See requirements for details.
# Requirements:
# None.
# Installation:
# Save this script as 'pingkick.py' in your <bf2>/admin/standard_admin directory,
# and add the lines 'import pingkick' and 'pingkick.init()' to the file
# '<bf2>/admin/standard_admin/__init__.py'.
#
# Changes from 1.0 to 1.1:
# - Added support for stand-alone operation. (Will use bf2.adminoptions if available)
# - The script now only checks ping while game status is 'Playing'
# - Switched from 'bfno' to prefix 'pk' for ping kick settings in 'bf2.adminoptions'.
# - Other, minor updates.
#
# Changes from 1.1. to 1.2:
# - Added methods to deactivate checking while players are not really playing.
# - Added safeguard against kicking a player that has gotten a disconnected "ping violater's" index.
# - Made the logging more verbose and ingame messaging less verbose.

# NB: These settings will be overridden by their counter-parts in
